Coalescence of drops in stirred dispersion. A white noise model for coalescence

Coalescence between two droplets in a turbulent liquid-liquid dispersion is generally viewed as a consequence of forces exerted on the drop-pair squeezing out the intervening continuous phase to a critical thickness. A new synthesis is proposed herein which models the film drainage as a stochastic process driven by a suitably idealized random process for the fluctuating force. While the true test of the model lies in detailed parameter estimations with measurement of drop-size distributions in coalescing dispersions, experimental measurements on average coalescence frequencies lend preliminary support to the model.

The purpose of this research was to examine teacher’s pedagogical thinking based on beliefs. It aimed to investigate and identify beliefs from teachers’ speech when they were reflecting their own teaching. Placement of beliefs in levels of pedagogical thinking was also examined. The second starting point for a study was the Instrumental Enrichment -intervention, which aims to enhance learning potential and cognitive functioning of students. The goal of this research was to investigate how five main principles of the intervention come forward in teachers’ thinking. Specifying research question was: how similar teachers’ beliefs are to the main principles of intervention. The teacher-thinking paradigm provided the framework for this study. The essential concepts of this study are determined exactly in the theoretical framework. Model of pedagogical thinking was important in the examination of teachers’ thinking. Beliefs were approached through the referencing of varied different theories. Feuerstein theory of Structural cognitive modifiability and Mediated learning experience completed the theory of teacher thinking. The research material was gathered in two parts. In the first part two mathematics lessons of three class teachers were videotaped. In second part the teachers were interviewed by using a stimulated recall method. Interviews were recorded and analysed by qualitative content analysis. Teachers’ beliefs were divided in themes and contents of these themes were described. This part of analysis was inductive. Second part was deductive and it was based on theories of pedagogical thinking levels and Instrumental Enrichment -intervention. According to the research results, three subcategories of teachers’ beliefs were found: beliefs about learning, beliefs about teaching and beliefs about students. When the teachers discussed learning, they emphasized the importance of understanding. In teaching related beliefs student-centrality was highlighted. The teachers also brought out some demands for good education. They were: clarity, diversity and planning. Beliefs about students were divided into two groups. The teachers believed that there are learning differences between students and that students have improved over the years. Because most of the beliefs were close to practice and related to concrete classroom situation, they were situated in Action level of pedagogical thinking. Some teaching and learning related beliefs of individual teachers were situated in Object theory level. Metatheory level beliefs were not found. Occurrence of main principles of intervention differed between teachers. They were much more consistent and transparent in the beliefs of one teacher than of the other two teachers. Differences also occurred between principles. For example reciprocity came up in every teacher’s beliefs, but modifiability was only found in the beliefs of one teacher. Results of this research were consistent with other research made in the field. Teachers’ beliefs about teaching were individual. Even though shared themes were found, the teachers emphasized different aspects of their work. Occurrence of beliefs that were in accordance with the intervention were teacher-specific. Inconsistencies were also found within teachers and their individual beliefs.

The starting point for this study was university teaching and teachers and specifically their changing role when confronting the Finnish University Reform and the student-focused theories of learning. Teachers’ pedagogical thinking and pedagogical content knowledge were also part of the theoretical framework. In the research of conceptions of and approaches to learning and teaching, the qualitative classifications of Säljö and Marton (1976; 1997), Ramsden (1992), Kember (1997) and Trigwell and Prosser (1999) were utilised. Two study questions were raised (1) What kind of conceptions of and approaches to learning do engineering science teachers have? and (2) What kind of conceptions of and approaches to teaching do engineering science teachers have? The relationship between teachers’ conceptions and teaching was also examined. The research material was collected in autumn 2008 by interviewing teachers and by observing teaching in the Department of Energy Technology at Helsinki University of Technology. Altogether two tutorials and ten lectures were observed. Each teacher of the observed lectures was interviewed once. The interviews were carried out as semi-structured theme interviews. In the analysis of the research material phenomenographical approach was adapted. The study revealed many kinds of conceptions of and approaches to learning and teaching in the teachers’ speech. On the basis of the research material, the conceptions and approaches that the teachers declare do not always reflect their actions in the teaching situation. The surface approaches to learning and teacher-focused approaches to teaching and conceptions of receiving and transmission of knowledge were parallel. Instead the teachers’ declarations of the deep approaches to learning and student-focused approaches to teaching were partly in conflict with how the teacher taught. When striving towards student-centered teaching culture attention should be paid to the development of teachers’ pedagogical thinking and pedagogical content knowledge. The culture and the structures of the educational institution should also be considered.

Structuring of the Curriculum Design: Content and Pedagogy Constructing the Whole The object of this qualitative study is to structure curriculum design by drawing from the characteristics of subject content and pedagogy. The aim is to first outline the forms of content and pedagogy within the National Core Curriculum for Basic Education. By analysing these forms I then aim to construct a general view of the curriculum’s structure and its developmental potential as it relates to both current and future pedagogical and intellectual interests. The written curriculum is examined as part of the educational guidance system, which means that it is an administrative and juridical document that governs teacher action and has a pedagogical and intellectual character. Didactical schools, curriculum ideologies and curriculum-determinants are all discussed as means of approaching the curriculum model. Curriculum content itself is defined by the different forms and conceptions of knowledge. The representation of curriculum content can be defined to be either specific or integrated. Curriculum pedagogy is in turn defined on the basis of the prevailing conception of learning and teaching. The pedagogy within the curriculum can be open or closed depending on the extent of pedagogical freedom allowed. An examination of the pedagogical dimension also covers the subject of the interfaces between formal education and informal learning, which must be taken into consideration when developing school pedagogy and therefore also in the curriculum. The data of the study consists of two curriculum documents: The Finnish National Core Curriculum for Basic Education issued in 1994 and the present National core curriculum for basic education issued in 2004. The primary method used in the study is theory-based content analysis. On the one hand the aim of the analysis is to determine if the structure, i.e., model, of the curricula is built from unconnected, self-contained elements, or whether the separate parts make a coherent whole. On the other hand, the aim is also to examine the pedagogical features the two curricula contain. The basis of the study is not the systematic comparison of the curriculum documents, yet an analysis of two very distinct documents must also be based on an examination of their inherent differences. The results of the study show that the content in the analysed documents is not integrated. The boundaries between divisions are clearly defined and the curricula are subject-oriented and based on theoretical propositional knowledge. The pedagogy is mainly closed and based on strong guidance of content, structured student evaluation and measurable learning experiences. However, curriculum documents do have representations of integrated content: the themes covered early on in the core curriculum guidelines of 1994 permeate systematically the different divisions of the curriculum. The core curriculum guidelines of 2004 in turn reveal skills which create connections between subjects. The guidelines’ utilise out-of-school environments and accommodate learner experiences, and focus on flexible studying and emphasize individual learner needs. These characteristics reveal an open form of pedagogy. In light of these results, it is possible to reach an understanding of the content and pedagogical development possibilities of the curriculum. The essential viewpoints are then the setting of thematically-oriented aims as a basis for content development, the curriculum’s pedagogical structuring on the basis of the learning process and the enhancement of connections between curricular content and pedagogy in a purposeful way. Keywords: curriculum, curriculum theory, curriculum design, core curriculum guidelines, teaching content, pedagogy

Opettajan ja vanhemman vuorovaikutus ja keskustelun kehykset koululaisen kehityskeskusteluissa

The aim of the study is to describe the consultation discussions between the teacher, parents and the student. The structure and the interaction of the conversation is in the focus of the study. The study explicates the organization of the interaction and orientation of the participants in the conversation. The study approaches conversation as a dynamic activity and studies it from the point of view of the participants. Assessment is one of the themes involved in the teacher-parent-student consultation discussions. Assessment as a duty of the school brings an institutional aspect in the conversation, but the ways it is implemented and expressed varies in the conversational situations. Participants communication and interaction in the situation influences the ways the consultation discussions are carried out. The framework of the study is based on the ethno methodological approach where a social situation and its meaning is seen negotiated by the participants. The interest of the study is to find out how the participants implement mutual understanding and how it can be observed in their interaction. Quantitatively, the interaction of the participants is described in the framework of the interaction analysis and linked to the socio-emotional and rational aspects of the interaction. The empirical part of the study consists of data collected with questionnaires and videotaped conversations. The main research problems of the study are, how the teachers and parents described the consultation discussions and how the interaction of the teacher, the parent and the student is organized during the conversation. The background of the study is linked to the previous studies concerning co-operation between the teacher and the parent and home-school relationship. This part of the study aims to enlighten how the consultation discussions are part of the co-operation in the school context. The questionnaires link the consultation discussions to the every day co-operation between the teacher and the family. Expectations and results described by the parents and teachers are analysed. Videotaped data is both analysed quantitatively based on interaction analysis and approached with the ethno methodological interpretation. The interest of my study is, how people participate in the situation of consultation discussion, how they orientate in it and influence the conversation. The analyses of the consultation discussions are based on the both quantitative interaction analysis and ethno methodological frame analysis. With the theoretical approach of my study I want to describe and enlighten the organization of the interaction and ways of orientation of the participants in consultation discussions. Keywords: consultation discussion, interaction, evaluation, orientation in the conversation, home-school cooperation, quantitative interaction analysis, frame analysis

Emotional intelligence development in student radiation therapists: A longitudinal pilot study

Emotional intelligence (EI) is defined as “the ability to recognise, understand and manage emotions in ourselves and others” [1]. Initially identified as a concept applied to leadership and management, EI is now recognised as an important skill in a number of areas, including healthcare [2]. Empathy (the ability to see the world through someone else’s eyes) is known to play an important role in the therapeutic relationship with patients [3]. As EI has been shown to improve empathy [4], it is clear that developing the EI of student health professionals should benefit patients in the long term. It is not surprising, then, that a number of studies have investigated the role of EI in medical, dental and nursing students, however there is little reported evidence relating to EI development in pre-registration radiation therapy (RT) students.

From a "Student" to a Lifelong "Consumer" : Constructions of Educability in Adult Students' Narrative Life Histories

The focus of this study was to examine the constructions of the educable subject of the lifelong learning (LLL) narrative in the narrative life histories of adult students at general upper secondary school for adults (GUSSA). In this study lifelong learning has been defined as a cultural narrative on education, “a system of political thinking” that is not internally consistent, but has contradictory themes embedded within it (Billig et al., 1988). As earlier research has shown and this study also confirms, the LLL narrative creates differences between those who are included and those who fall behind and are excluded from the learning society ideal. Educability expresses socially constructed interpretations on who benefit from education and who should be educated and how. The presupposition in this study has been that contradictions between the LLL narrative and the so-called traditional constructions of educability are likely to be constructed as the former relies on the all-inclusive interpretation of educability and the latter on the meritocratic model of educating individuals based on their innate abilities. The school system continues to uphold the institutionalized ethos of educability that ranks students into the categories “bright”, “mediocre”, and “poor” (Räty & Snellman, 1998) on the basis of their abilities, including gender-related differences as well as differences based on social class. Traditional age-related norms also persist, for example general upper secondary education is normatively completed in youth and not in adulthood, and the formal learning context continues to outweigh both non-formal and informal learning. Moreover, in this study the construction of social differences in relation to educability and, thereafter unequal access to education has been examined in relation to age, social class, and gender. The biographical work of the research participants forms a peephole that permits the examination of the dilemmatic nature of the constructions of educability in this study. Formal general upper secondary education in adulthood is situated on the border between the traditional and the LLL narratives on educability: participation in GUSSA inevitably means that one’s ability and competence as a student and learner becomes reassessed through the assessment criteria maintained by schools, whereas according to the principles of LLL everyone is educable; everyone is encouraged to learn throughout their lives regardless of age, social class, or gender. This study is situated in the field of adult education, sociology of education, and social psychological research on educability, having also been informed by feminist studies. Moreover, this study contributes to narrative life history research combining the structural analysis of narratives (Labov & Waletzky, 1997), i.e. mini-stories within life history, with the analysis of the life histories as structural and thematic wholes and the creation of coherence in them; thus, permitting both micro and macro analyses. On accounting for the discontinuity created by participation in general upper secondary school study in adulthood and not normatively in youth, the GUSSA students construct coherence in relation to their ability and competence as students and learners. The seven case studies illuminate the social differences constructed in relation to educability, i.e. social class, gender, age, and the “new category of student and learner”. In the data of this study, i.e. 20 general upper secondary school adult graduates’ narrative life histories primarily generated through interviews, two main coherence patterns of the adult educable subject emerge. The first performance-oriented pattern displays qualities that are closely related to the principles of LLL. Contrary to the principles of lifewide learning, however, the documentation of one’s competence through formal qualifications outweighs non-formal and informal learning in preparation for future change and the competition for further education, professional careers, and higher social positions. The second flexible learning pattern calls into question the status of formal, especially theoretical and academically oriented education; inner development is seen as more important than such external signs of development — grades and certificates. Studying and learning is constructed as a hobby and as a means to a more satisfactory life as opposed to a socially and culturally valued serious occupation leading to further education and career development. Consequently, as a curious, active, and independent learner, this educable but not readily employable subject is pushed into the periphery of lifelong learning. These two coherence patterns of the adult educable subject illuminate who is to be educated and how. The educable and readily employable LLL subject is to participate in formal education in order to achieve qualifications for working life, whereas the educable but not employable subject may utilize lifewide learning for her/his own pleasure. Key words: adult education, general upper secondary school for adults, educability, lifelong learning, narrative life history

The influence of a novel simulated learning environment upon student clinical subjective refraction performance: A pilot study

Background: Optometry students are taught the process of subjective refraction through lectures and laboratory based practicals before progressing to supervised clinical practice. Simulated learning environments (SLEs) are an emerging technology that are used in a range of health disciplines, however, there is limited evidence regarding the effectiveness of clinical simulators as an educational tool. Methods: Forty optometry students (20 fourth year and 20 fifth year) were assessed twice by a qualified optometrist (two examinations separated by 4-8 weeks) while completing a monocular non-cycloplegic subjective refraction on the same patient with an unknown refractive error simulated using contact lenses. Half of the students were granted access to an online SLE, The Brien Holden Vision Institute (BHVI®) Virtual Refractor, and the remaining students formed a control group. The primary outcome measures at each visit were; accuracy of the clinical refraction compared to a qualified optometrist and relative to the Optometry Council of Australia and New Zealand (OCANZ) subjective refraction examination criteria. Secondary measures of interest included descriptors of student SLE engagement, student self-reported confidence levels and correlations between performance in the simulated and real world clinical environment. Results: Eighty percent of students in the intervention group interacted with the SLE (for an average of 100 minutes); however, there was no correlation between measures of student engagement with the BHVI® Virtual Refractor and speed or accuracy of clinical subjective refractions. Fifth year students were typically more confident and refracted more accurately and quickly than fourth year students. A year group by experimental group interaction (p = 0.03) was observed for accuracy of the spherical component of refraction, and post hoc analysis revealed that less experienced students exhibited greater gains in clinical accuracy following exposure to the SLE intervention. Conclusions: Short-term exposure to a SLE can positively influence clinical subjective refraction outcomes for less experienced optometry students and may be of benefit in increasing the skills of novice refractionists to levels appropriate for commencing supervised clinical interactions.

This is a case-study of students well-being studying in Sibelius Upper Secondary School which has got a special educational task in dance and music. The first purpose of this study is to analyse the students well-being, motivation, studying satisfaction and try to find out what kind of problems the students meet when studying in Upper Secondary School. The second purpose of this study is to try find means in counselling to help students in their Upper Secondary School Studies. The data were gathered in three parts. The first questioning was based on Allardt s (1976; 1998) well-being theory. In this questioning (N = 187) the students described their satisfaction in having (material things), loving (social relationships) and being (free time). The second data was collected by interviews (N = 19). The third data is a follow-up questioning (N = 10) for graduated students. The whole data was analysed with qualitative methods. The gathered qualitative data were compared with the quantitative data gathered by the National Institute for Health and Welfare. Results of this study indicate that the students in this case-study are mainly satisfied with their well-being, social and material things in their studying environment including counselling and teaching. The research results show that some of the students are exhausted due too muchtime spent in studying. This was verified also in the quantitative data gathered by the National Institute for Health and Welfare. These students suffer for the lack of free time and rest. Students who are motivated and have reached the autonomous way of studying do better in their Upper Secondary School Studies than those who study in unautonomous way.A quite wide range of students tend to make individual studying programmes and spend four or more years in Upper Secondary School instead of the three year programme. The individual programme gives them more time for practicing their special skills in the field of the school s special educational task and to give themselves more time for studying the basic subjects of the Upper Secondary School. Some of the students who tend to take extra years in Upper Secondary School have difficulties in their studying skills and are unsure of their studying motivation. The competition among students in Upper Secondary School with the special educational task causes stress and exhaustion for some of the studied students. These students have difficulties with integrating themselves into the social environment. For the other students the school s social environment works as a motivator for their studies and increases their well-being in their studies. According to the results of the follow-up questioning in this study the students value most the network with the other students they made while studying at the Sibelius Upper Secondary School. According to this study the students would need more counselling in all stages of their Upper Secondary School Studies. The autonomous students do quite well in their studies despite of the small amount of given counselling. They would also need more counselling in planning their further studies after Upper Secondary School. The biggest challenges to student counselling in Sibelius Upper Secondary School are helping the students to find their individual ways of studying and helping them to learn the ways of autonomous studying skills.

Matkalla suomalaiseksi ja hoiva-alan ammattilaiseksi? : Venäläis- ja virolaistaustaisten naisten ja suomalaisuuden kohtaamiset kuulumista rakentamassa

The research examines the process by which a sense of belonging to Finnish society is constructed among women of Russian and Estonian background who are multiply marginalised in Finnish society. It does so by analysing the encounters between their nationality and 'being Finnis'. Attention is focused on the question of what kind of "journey" they take after moving to Finland, how a sense of belonging is constructed especially along the paths followed in education and at work, and what kind of agency is available to them. The thesis is connected with post-colonial research and also draws from studies on citizenship and nationality as well as the social structures of interaction, when analysing careers. As the educational system forms the most central context of the research, the work is also focused on educational sociology. The research methodology includes life history and a narrative approach. The raw data is from thematic interviews concerning the life experiences of women of immigrant backgrounds. They were studying in Finland to be practical nurses or to complete Bachelor of Social Service degree. According to the study, the women had been encountered as alien, strange, and carrying a shade of "otherness". The experience of inclusion in Finnish communities and society turned out to be conditional, an inclusion based on the notion of a citizen worker, which is defined by national needs. The person from abroad is placed in the position of someone who fills gaps in the services of the welfare state. The choice of education in the care sector and the overall necessity of obtaining Finnish education turned out to be socially directed. Gendered structures of education and working life were found to act as a frame in which the decisions of the immigrant women were made. Although national education policy emphasis as an orientation to global labour markets, the immigrant student is placed above all in the position of an object to be made suitable for the Finnish labour market. Citizenship, a goal of education, requires consent to being "socialised" into Finnish society as well as learning to be Finnish. One s only option to negotiate appearing suitable as a member is to construct oneself into someone who adopts Finnish and Western cultural values, values which favour individuality. However, Finnish education is a resource to Finnishness. Finnish education enables a sense of being Finnish, and empowers the job applicant for example, and in addition to providing cultural, human and social capital strengthen inclusion as well. The study confirms the view that the encounter of an immigrant is still characterised by its colonial nature. It shows that encounters with Finns and Finnish society place the person of immigrant background, even one receiving a Finnish education, in the position of "the other". The journey as an immigrant continues. The immigrant has access only to certain predefined subject positions, which limits agency. When categorised as an immigrant, one becomes a per-son who is different and "other", while the sense of belonging as a member of Finnish society without conditions appears to be somewhat unreachable. Yet, new arrivals are capable of acting change. An immigrant woman can challenge the positions offered to her and present herself as strong. Her life story has often included struggle, and she has the fortitude strength to change her circumstances. Key words: life story, post-colonial encounter, nationality, citizenship, the career of immi-grant, position, agency

Why are students choosing STEM and when do they make their choice?

BACKGROUND OR CONTEXT The higher education sector plays an important role in encouraging students into the STEM pipeline through fostering partnerships with schools, building on universities long tradition in engagement and outreach to secondary schools. Numerous activities focus on integrated STEM learning experiences aimed at developing conceptual scientific and mathematical knowledge with opportunities for students to show and develop skills in working with each other and actively engaging in discussion, decision making and collaborative problem solving. (NAS, 2013; AIG, 2015; OCS, 2014). This highlights the importance of the development and delivery of engaging integrated STEM activities connected to the curriculum to inspire the next generation of scientists and engineers and generally preparing students for post-secondary success. The broad research objective is to gain insight into which engagement activities and to what level they influence secondary school students’ selection of STEM-related career choices at universities. PURPOSE OR GOAL To evaluate and determine the effectiveness of STEM engagement activities impacting student decision making in choosing a STEM-related degree choice at university. APPROACH A survey was conducted with first-year domestic students studying STEM-related fieldswithin the Science and Engineering Faculty at Queensland University of Technology. Of the domestic students commencing in 2015, 29% responded to the survey. The survey was conducted using Survey Monkey and included a variety of questions ranging from academic performance at school to inspiration for choosing a STEM degree. Responses were analysed on a range of factors to evaluate the influence on students’ decisions to study STEM and whether STEM high school engagement activities impacted these decisions. To achieve this the timing of decision making for students choice in study area, degree, and university is compared with the timing of STEM engagement activities. DISCUSSION Statistical analysis using SPSS was carried out on survey data looking at reasons for choosing STEM degrees in terms of gender, academic performance and major influencers in their decision making. It was found that students choose their university courses based on what subjects they enjoyed and exceled at in school. These results found a high correlation between enjoyment of a school subject and their interest in pursuing this subject at university and beyond. Survey results indicated students are heavily influenced by their subject teachers and parents in their choice of STEM-related disciplines. In terms of career choice and when students make their decision, 60% have decided on a broad area of study by year 10, whilst only 15% had decided on a specific course and 10% had decided on which university. The timing of secondary STEM engagement activities is seen as a critical influence on choosing STEM disciplines or selection of senior school subjects with 80% deciding on specific degree between year 11 and 12 and 73% making a decision on which university in year 12. RECOMMENDATIONS/IMPLICATIONS/CONCLUSION Although the data does not support that STEM engagement activities increase the likelihood of STEM-related degree choice, the evidence suggests the students who have participated in STEM activities associate their experiences with their choice to pursue a STEM-related course. It is important for universities to continue to provide quality engaging and inspirational learning experiences in STEM, to identify and build on students’ early interest and engagement, increase STEM knowledge and awareness, engage them in interdisciplinary project-based STEM practices, and provide them with real-world application experiences to sustain their interest.

Kivaa ja hyödyllistä, mutta jo se riittää : Yläasteen kielikylpyoppilaiden käsityksiä ruotsinkielisestä kielikylpyopetuksesta Helsingissä

The aim of this study was to find out how immersion students experience immersion education, how they feel about the implementation of immersion education methods and what role immersion plays in immersion students’ lives outside the school context. In addition, the influence of sex, grade level, school and type of immersion education on students’ perceptions was studied. The population included all students at the lower secondary level in Helsinki who participated in Swedish immersion education during 2002–2003. The sample consisted of 128 students who represented two different forms of immersion: 47% of the students had previously participated in early total immersion while 53 % of the students had taken part in early partial immersion. The data were gathered through a questionnaire and interviews. All 128 students answered the questionnaire, and 10 students were chosen to focus interviews through purposive sampling. In addition, students’ parents were invited to fill in a questionnaire where students’ background information was requested. The data were collected during the spring of 2003. Principal Component Analysis and one-way variance analysis were used as statistical analysis methods. Also frequencies, average, correlations and cross tabs were studied. In the PCA a right-angled varimax-rotation was performed separately to every thematic entity that arose from the theoretical background. Sum variables were formed from the Principal Components by summing up all the items that received over .400 charges for the specific Principal Component. Significance testing of the mean was performed with F and t-tests. Results indicate that immersion students in lower secondary school experience immersion quite diversely as a whole. Students are satisfied with the fact that they are in the immersion class but not with the amount of teaching in Swedish. Students feel it is very important and useful to learn Swedish bearing in mind their future studies and working life. The students estimate their language skills to be very high. Yet they prefer using Finnish during classes. The fact that teachers use Swedish does not considerably affect how well the students learn the factual content in various subjects, especially if the student knows Swedish well. Theoretical subjects seemed to cause most problems. Swedish played only a very small part in students’ lives outside the school context and it was used merely when travelling abroad and in different kinds of guiding situations. Unless the students were talked to in Swedish, they kept on speaking Finnish. When asked about students’ experiences no statistically significant differences between sexes were found in this study. On the contrary, in some cases their grade level but especially their school and form of immersion had clear statistically significant differences on students’ perceptions.

Käsityökohtaamisia muinaisuuden kanssa : Neulalla neulominen eli kinnasneulatekniikka ...muutakin kuin neulakinnas?

The aim of this study was to find out how the technique of knotless netting is perceived by the craftsperson of the twenty first century. In this study the craftspeople are represented by the researcher herself, seven craftspeople and teachers (3) teaching knotless netting as well as their students (21). The main interests of this study are the mental pictures and relationship to knotless netting that craftspeople have in the twenty first century. Points of focus are also the specific characteristics of knotless netting, as well as experimenting with new and different materials. The aim of these experiments has been to find new and unusual uses for knotless netting. Preserving knotless netting as a craft and technique are also questions dealt with in this study. The methodology of this study is a qualitative and phenomenographic study of several cases. The data collected are interviews of the teachers, observations in two knotless netting courses, questionnaires answered by the students in these courses and experimental samples made by the author and evaluated by other craftspeople. These samples were made during the years 2005-2008. The interviews, questionnaires and evaluations were conducted under winter and spring 2008. The reference literature is comprised from publications in several different fields. In this study ethnography is the most dominant field of reference due to the fact that knotless netting is so strongly linked to history and antiquity. In the past the technique of knotless netting has been passed down from generation to generation in whatever form the teacher has known. There are many different ways of stitching and binding in knotless netting. This technique is closely connected to traditional knotless netting mittens even today. Nowadays knotless knitting is taught in craft schools, evening classes and in other recreational courses. The concrete understanding of knotless netting by means of two-dimensional instructions is challenging. Craftspeople often require somebody to actually demonstrate the correct way to make the stitches and hold the work before they can proceed with the technique. The way knotless netting is perceived by craftspeople is linked to their backgrounds and preconstructed mental images concerning the technique. An etnographer approaches knotless netting in a different way from a crafts-scientist or a person in an evening class wishing to master the technique. The attitude of the teacher is passed on to students and also affects the way the student perceives knotless netting and its possibilities as a technique. A craftsperson has mixed feelings toward knotted netting. On the other hand the surfaces produced by this rare technique are intriguing but the costs due to the slow manufacturing process are seen as an encumbrance.

Oikein, nurin - miten Suomessa kudin : Tutkimus neulonnan työotteista.

The aim of this work was to study what kind of working grips people use to knit in Finland and decide if one grip is superior to others. I investigated how knitters have adopted their grips and how they experience their knitting. I also explored whether it is possible to change one's grip. To provide a theoretical basis for the research I observed knitting in terms of culture, skill and ergonomics. The first part of the study material comprised video recordings of the grips of 95 knitters together with background information collected via a questionnaire during the education of craft teachers at the University of Helsinki in spring 2004, 2005 and 2006. Using the data obtained I focused on three knitters, whose grip of the knitting needles clearly differed from the ergonomically good grip. In addition to them I interviewed one student, who had changed over to more ergonomic way of knitting after participating in the first part of this study. In this respect my study is a several events' case study. In order to analyse my data I used both qualitative and quantitative content analysis methods to complement each other. Most of my research participants had learned to knit in first years of elementary school or comprehensive school. Almost everyone had adopted the basics of knitting by imitating, and many of them had corrected "incorrect" positions from verbal instructions. Through practice the imitated position had gradually become the style unique to each knitter. The findings showed that students' background in knitting is quite varied due to the diverse level of craft teaching. This is reflected in their knitting grips and their interest in knitting. Students do not think that there is one right working grip. The most important thing is that working seems as fluent and relaxed as possible, at which point knitting is easy and flows freely. They often consider their own style so pleasing and well-functioning that they do not think there could be any room for improvement. This study pointed out that, while it is possible to change a knitter's working grip, there is a bigger challenge in acknowledging weaknesses in one's know how. According to the results of my research, the most common working grip among Finnish knitters' corresponds with the grip that has been described as ergonomically good. Over one third of all participants knitted this way. Hands keep the knitting firmly but without tension. The forefinger that guides the yarn from the ball rests gently against the knitting needle, and the yarn goes in front of the first joint of the forefinger. The position of the hands and loops is the same as in the ergonomically good grip, i.e. the fingertips of both hands and the loops are near the tips of the knitting needles, so that the fingers only have to move small distances. When knitters purl and plain, they commonly pick up the yarn from the back of the knitting needle in the same way as when knitting. While researching the common features of working grips I have learned what abnormal grips are like. Although I recognized many different ways to knit, all the peculiar grips were modifications of the continental way of knitting. The results of this study give a clear picture of those points knitters should focus their attention on in order to gain a good hold of the needles.
