Holistic physics education in upper secondary level based on the optional course of physics Keywords: physics education, education, holistic, curriculum, world view, values A physics teacher s task is to put into practice all goals of the curriculum. Holistic physics education means in this research teaching, in which the school s common educational goals and the goals particular to the physics curriculum are taken into account. These involve knowledge, skills and personal value and attitude goals. Research task was to clarify how the educational goals involving student s values and attitudes can be carried out through the subject content of physics. How does the physics teacher communicate the modern world view through the content of the physics class? The goal of this research was to improve teaching, to find new points of view and to widen the perspective on how physics is taught. The teacher, who acted also as a researcher, planned and delivered an optional course where she could study the possibilities of holistic physics education. In 2001-2002 ten girls and two boys of the grade 9th class participated in that elective course. According to principles of action research the teacher-researcher reflected also on her own teaching action. Research method was content analysis that involved both analyzing student feedback, and relevant features of the teacher s knowledge, which are needed for planning and giving the physics lessons. In this research that means taking into account the subject matter knowledge, curriculum, didactic and the pedagogical content knowledge of the teacher. The didactic includes the knowledge of the learning process, students motivation, specific features of the physics didactics and the research of physics education. Among other things, the researcher constructed the contents of the curriculum and abstracted sentences as keywords, from which she drew a concept map. The concept maps, for instance, the map of educational goals and the mapping of the physics essence, were tools for studying contents which are included in the holistic physics education. Moreover, conclusions were reached concerning the contents of physics domains by which these can be achieved. According to this research, the contents employing the holistic physics education is as follows: perception, the essence of science, the development of science, new research topics and interactions in physics. The starting point of teaching should be connected with the student s life experiences and the approach to teaching should be broadly relevant to those experiences. The teacher-researcher observed and analyzed the effects of the experimental physics course, through the lens of a holistic physics education. The students reported that the goals of holistic physics education were achieved in the course. The discourses of the students indicated that in the experimental course they could express their opinions and feelings and make proposals and evaluations. The students had experiences about chances to affect the content of the course, and they considered the philosophical physics course interesting, it awakened questions, increased their self-esteem and helped them to become more aware of their world views. The students analytic skills developed in the interactive learning environment. The physics teacher needs broad knowledge for planning his or her teaching, which is evaluated in this research from contents maps made for the tools of the teaching. In the holistic physics education the teacher needs an open and curious mind and skills for interaction in teaching. This research indicates the importance of teaching physics in developing attitudes and values beside substance of the physics in class environment. The different points of view concerning human beings life make it possible to construct the modern world view of the students and to develop analytic skills and the self-esteem and thus help them in learning. Overall and wide points of view also help to transfer knowledge to practice. Since such contents is not employed by teaching the physics included in the standard curriculum, supplement relevant teaching material that includes such topics are needed.

Enhancing Physics Education in the National Defence University : A design based research approach in the production of learning material

This research is connected with an education development project for the four-year-long officer education program at the National Defence University. In this curriculum physics was studied in two alternative course plans namely scientific and general. Observations connected to the later one e.g. student feedback and learning outcome gave indications that action was needed to support the course. The reform work was focused on the production of aligned course related instructional material. The learning material project produced a customized textbook set for the students of the general basic physics course. The research adapts phases that are typical in Design Based Research (DBR). The research analyses the feature requirements for physics textbook aimed at a specific sector and frames supporting instructional material development, and summarizes the experiences gained in the learning material project when the selected frames have been applied. The quality of instructional material is an essential part of qualified teaching. The goal of instructional material customization is to increase the product's customer centric nature and to enhance its function as a support media for the learning process. Textbooks are still one of the core elements in physics teaching. The idea of a textbook will remain but the form and appearance may change according to the prevailing technology. The work deals with substance connected frames (demands of a physics textbook according to the PER-viewpoint, quality thinking in educational material development), frames of university pedagogy and instructional material production processes. A wide knowledge and understanding of different frames are useful in development work, if they are to be utilized to aid inspiration without limiting new reasoning and new kinds of models. Applying customization even in the frame utilization supports creative and situation aware design and diminishes the gap between theory and practice. Generally, physics teachers produce their own supplementary instructional material. Even though customization thinking is not unknown the threshold to produce an entire textbook might be high. Even though the observations here are from the general physics course at the NDU, the research gives tools also for development in other discipline related educational contexts. This research is an example of an instructional material development work together the questions it uncovers, and presents thoughts when textbook customization is rewarding. At the same time, the research aims to further creative customization thinking in instruction and development.

Virtual versus classroom language teaching : A comparative study of the learning outcomes and student responses between two English reading comprehension groups

A 26-hour English reading comprehension course was taught to two groups of second year Finnish Pharmacy students: a virtual group (33 students) and a teacher-taught group (25 students). The aims of the teaching experiment were to find out: 1.What has to be taken into account when teaching English reading comprehension to students of pharmacy via the Internet and using TopClass? 2. How will the learning outcomes of the virtual group and the control group differ? 3. How will the students and the Department of Pharmacy respond to the different and new method, i.e. the virtual teaching method? 4. Will it be possible to test English reading comprehension learning material using the groupware tool TopClass? The virtual exercises were written within the Internet authoring environment, TopClass. The virtual group was given the reading material and grammar booklet on paper, but they did the reading comprehension tasks (written by the teacher), autonomously via the Internet. The control group was taught by the same teacher in 12 2-hour sessions, while the virtual group could work independently within the given six weeks. Both groups studied the same material: ten pharmaceutical articles with reading comprehension tasks as well as grammar and vocabulary exercises. Both groups took the same final test. Students in both groups were asked to evaluate the course using a 1 to 5 rating scale and they were also asked to assess their respective courses verbally. A detailed analysis of the different aspects of the student evaluation is given. Conclusions: 1.The virtual students learned pharmaceutical English relatively well but not significantly better than the classroom students 2. The overall student satisfaction in the virtual pharmacy English reading comprehension group was found to be higher than that in the teacher-taught control group. 3. Virtual learning is easier for linguistically more able students; less able students need more time with the teacher. 4. The sample in this study is rather small, but it is a pioneering study. 5. The Department of Pharmacy in the University of Helsinki wishes to incorporate virtual English reading comprehension teaching in its curriculum. 6. The sophisticated and versatile TopClass system is relatively easy for a traditional teacher and quite easy for the students to learn. It can be used e.g. for automatic checking of routine answers and document transfer, which both lighten the workloads of both parties. It is especially convenient for teaching reading comprehension.

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.

Levottomat Tuhkimot : Etnografinen tutkimus nuorten tyttöjen suhtautumisesta väkivaltaan Levottomat Tuhkimot -tyttöväkivaltaprojektin keskusteluryhmässä

In recent years girls’ increased violence has been a topical issue. Including the voices of the girls’ themselves engaged to violent offending is therefore essential. The goal for this research was to make sense of girls’ stance toward violence in the project Restless Cinderellas’ discussion group for violent girls. The methodological approach was ethnographic and the data was collected by using the method of participant observation. Girls’ stance toward violence was explored by asking the data following questions: 1. What is the purpose of violent behaviour? 2. Which issues motivate for violence? 3. What alternatives exist for violent behaviour? In a thick description of research material this study also aimed to chart if there was any change in girls’ attitudes due to participation on violence preventative discussion group. The ethnographic data was extensive and consisted of observations, start, - middle, - and end point group discussion records, fieldnotes, self report-questionnaires and feedback documentary. The four girls that participated on this study were 14 -15- years old by the time of research. They came from one elementary school in the capital region. They were chosen to the group based on NFG’s youth workers interview. The girls were allocated to the group by the school’s student welfare group because of their violent behaviour on school time. The analysis was qualitative and the concepts were created through theory triangulation. These concepts were exploited to exam girls’ violent attitudes. The study shows that violence was used to pitch for justice, lesson and respect. The factors that motivated on using violence were experienced insult, betrayal and concatenation of violence. Alternatives for violence were the circle of success and value consciousness. In the dialectics between the research documentaries some changes in girls’ attitudes heaved into sight. However, the study could not show reliable connection between the changes and participation on discussion group.

Stiffer Optical Tweezers through Real-Time Feedback Control

This thesis integrates real-time feedback control into an optical tweezers instrument. The goal is to reduce the variance in the trapped bead s position, -effectively increasing the trap stiffness of the optical tweezers. Trap steering is done with acousto-optic deflectors and control algorithms are implemented with a field-programmable gate array card. When position clamp feedback control is on, the effective trap stiffness increases 12.1-times compared to the stiffness without control. This allows improved spatial control over trapped particles without increasing the trapping laser power.

Evaluation of Vestibular Function with Visual Feedback Posturography and Motorized Head Impulse Test.

Objectives: To evaluate the applicability of visual feedback posturography (VFP) for quantification of postural control, and to characterize the horizontal angular vestibulo-ocular reflex (AVOR) by use of a novel motorized head impulse test (MHIT). Methods: In VFP, subjects standing on a platform were instructed to move their center of gravity to symmetrically placed peripheral targets as fast and accurately as possible. The active postural control movements were measured in healthy subjects (n = 23), and in patients with vestibular schwannoma (VS) before surgery (n = 49), one month (n = 17), and three months (n = 36) after surgery. In MHIT we recorded head and eye position during motorized head impulses (mean velocity of 170º/s and acceleration of 1 550º/s²) in healthy subjects (n = 22), in patients with VS before surgery (n = 38) and about four months afterwards (n = 27). The gain, asymmetry and latency in MHIT were calculated. Results: The intraclass correlation coefficient for VFP parameters during repeated tests was significant (r = 0.78-0.96; p < 0.01), although two of four VFP parameters improved slightly during five test sessions in controls. At least one VFP parameter was abnormal pre- and postoperatively in almost half the patients, and these abnormal preoperative VFP results correlated significantly with abnormal postoperative results. The mean accuracy in postural control in patients was reduced pre- and postoperatively. A significant side difference with VFP was evident in 10% of patients. In the MHIT, the normal gain was close to unity, the asymmetry in gain was within 10%, and the latency was a mean ± standard deviation 3.4 ± 6.3 milliseconds. Ipsilateral gain or asymmetry in gain was preoperatively abnormal in 71% of patients, whereas it was abnormal in every patient after surgery. Preoperative gain (mean ± 95% confidence interval) was significantly lowered to 0.83 ± 0.08 on the ipsilateral side compared to 0.98 ± 0.06 on the contralateral side. The ipsilateral postoperative mean gain of 0.53 ± 0.05 was significantly different from preoperative gain. Conclusion: The VFP is a repeatable, quantitative method to assess active postural control within individual subjects. The mean postural control in patients with VS was disturbed before and after surgery, although not severely. Side difference in postural control in the VFP was rare. The horizontal AVOR results in healthy subjects and in patients with VS, measured with MHIT, were in agreement with published data achieved using other techniques with head impulse stimuli. The MHIT is a non-invasive method which allows reliable clinical assessment of the horizontal AVOR.

Uusien opiskelijoiden integroituminen yliopistoon : Sosiaalipsykologinen näkökulma

The first year at the university is critical in shaping the student s future academic development. Student integration has been shown to affect learning, motivation, persistence, and ultimately, graduation. Most importantly, however, integration affects how students academic expertise develops. In this study a social-psychological assumption was made: one cannot grow into academic expertise in isolation, without interaction with teachers and peers. Integration happens via engagement. In this research, social and academic integration among Finnish freshmen was studied. How much did freshmen interact with their teachers and peers; how interested did they think their teachers were in students; how committed did they feel; and how did they assess their own academic development? In addition to integration, students were asked about their identification with the university and the frequency of actual contacts with teachers and peers. Lastly, students personal epistemologies were studied to see if they were related to integration or frequency of contacts. The data was collected at the University of Helsinki in the autumn of 2001 and spring of 2002 at three faculties: the faculty of Social Sciences, Humanities and Science. In the autumn, 270 freshmen, and in the spring, 400 freshmen, completed the questionnaire. In addition to the cross-sectional data a longitudinal data was formed from 77 of the respondents. The results showed differences in how students were integrated. Freshmen at the faculty of Science were the least integrated whereas freshmen at the faculty of Humanities were the most integrated. Identification to the university was positively related to integration. The frequency of contacts with faculty and peers was positively related to integration and identification. A more developed personal epistemology was also positively related to integration and frequency of contacts. Differences were also found between the sexes in frequency of peer interaction and level of epistemology. This study has both theoretical and practical implications. Positive correlations between integration, identification, frequency of contacts and personal epistemology were found. The guiding assumption of the significance of social interaction was thus supported. The practical relevance of the study is for how teaching is carried out. In this data, over 50% of new university students at the end of their first year said they had never received feedback from an exam, never had a discussion with their teacher about a scientific topic, and had never discussed with a teacher how their studies were going.

Working with Identities Promoting Student Teachers Professional Development

The starting point of the study was that good teaching requires a teacher to be aware of the sources of his or her pedagogical decisions; that is, personal values, beliefs and understandings. From this perspective, a teacher s professional development refers to a process of extending one s self-knowledge. The aim of this study was to promote student teachers' professional development with the help of identity work. Identity work refers to reflecting on both personal and professional experiences. Identity work consists of student teachers self-reflection on their life experiences (self-identity) and video diary-based reflection on their classroom practice (professional identity). The research questions of the study were 1) how is identity work manifested by the participants? and 2) what is the potential of identity work in promoting student teachers professional development? The research data was collected from four student teachers in the academic year 2007-2008; the research group had 24 meetings during the research process. Student teachers take part in a multimode teacher education programme, where students work as ordinary teachers in schools during their university studies. The data collection was conducted by using two methods: participants narratives based on autobiographical writings and video diaries based on participants lessons. Narrative research data was analysed by employing qualitative methods and strategies as they were needed in the research. The research results revealed four different ways of working with identities, each of them revealing different aspects of and approaches to identity work. The results also showed that identity work has the potential to promote professional development. As the research progressed, there were visible changes in the participants reflection. However, despite encouraging results, some issues should be critically questioned. Although reflection sounds attractive and fruitful as a tool for promoting professional development, there are also difficulties and obstacles. On the basis of the results, a proposal for promoting student teachers professional development is offered. Keywords: Teacher identity, identity work, reflection, teacher professional development

Oikeustieteen ensimmäisen vuoden opiskelijoiden haasteet opiskelussa

The aim of this dissertation was to explore factors which affect first-year law students study success. A modified Biggs s 3P model was used as the theoretical framework. The model includes both personal and contextual factors in student learning. The participants were first-year law students from the academic years 2005-2008, and the data were collected through interviews, open-ended question and electronic questionnaires. Study I explored first-year law students spontaneous descriptions of their learning activities at the beginning of their studies as well as fast study pace law students who had already finished their first year. Even though, law students are selected through a demanding entrance examination, some of the beginner students mentioned using only one or very few learning activities, which were mainly non-generative strategies. On the other hand, it was typical for the fast study pace students to mention generative strategies and elements of organised effort in studying. Study II analysed the relationship between approaches to learning and study success in terms of earned study credits and grade point average among first-year law students in three years. Organised students and students applying a deep approach earned the highest number of credits and the highest grades, whereas students applying a surface approach and unorganised students applying a deep approach received the lowest number of credits and the lowest grades. The study confirms previous findings that organised students constitute the largest cluster among first-year law students. Study III explored factors affecting the study pace of law students during their first academic year. The factors mentioned by the students were classified into four categories of self-regulation: motivation, behaviour, cognition and context. The group of fast study pace students turned out to have good skills in all areas of self-regulation. Respectively, the slow study pace group showed more individual variation, and had weaknesses in one or more areas of self-regulation. In addition, students experienced, that other activities such as working affected their study pace, this could be constitute a fifth category. However, the slow and fast study pace students felt differently about work. According to the slow study pace students, work impeded their studying because it took up too much time. For their part, the fast study pace students were able to allocate their time effectively and felt working to be useful and a counterbalanced to their studying, as well as an opportunity to apply knowledge in practice. Study IV analysed differences in law students perceptions of their teaching-learning environments after three learning periods. The students perceptions were compared with pharmacy and veterinary students perceptions of their teaching-learning environments. The results showed that the law students experienced their teaching-learning environment more negatively than the pharmacy and veterinary students. The law students experienced that alignment, teaching for understanding, staff enthusiasm and support, along with constructive feedback were areas that could be developed at the Faculty. Together the four studies indicate that both law students learning skills and the teaching-learning environment could be further developed. The results imply that managing in the demanding teaching-learning environment of law requires student to effectively employ qualitative learning activities: organised studying and a deep approach to learning and good self-regulation skills. In addition to student counselling, it is important for students study success to direct the teaching-learning environment towards a more learning-focused than content-focused approach to teaching.

Dimensions of University Student Learning in Medicine and Pharmacy

Study orientations in higher education consist of various dimensions, such as approaches to learning, conceptions of learning and knowledge (i.e. epistemologies), self-regulation, and motivation. They have also been measured in different ways. The main orientations typically reported are reproducing and meaning orientations. The present study explored dimensions of study orientations, focusing in particular on pharmacy and medicine. New versions of self-report instruments were developed and tested in various contexts and in two countries. Furthermore, the linkages between study orientations and students epistemological development were explored. The context of problem-based (PBL) small groups was investigated in order to better understand how collaboration contributes to the quality of learning. The participants of Study I (n=66) were pharmacy students, who were followed during a three-year professionally oriented program in terms of their study orientations and epistemologies. A reproducing orientation to studying diminished during studying, whereas only a few students maintained their original level of meaning orientation. Dualism was found to be associated with a reproducing orientation. In Study II practices associated with deep and surface approaches to learning were measured in two differing ways, in order to better distinguish between what students believed to be useful in studying, and the extent to which they applied their beliefs to practice when preparing for examinations. Differences between domains were investigated by including a sample of Finnish and Swedish medical students (n=956) and a Finnish non-medical sample of university students (n=865). Memorizing and rote learning appeared as differing components of a surface approach to learning, while understanding, relating, and critical evaluation of knowledge emerged as aspects of a deep approach to learning. A structural model confirmed these results in both student samples. Study III explored a wide variety of dimensions of learning in medical education. Swedish medical students (n=280) answered the questionnaire. The deep approach to learning was strongly related to collaboration and reflective learning, whereas the surface approach was associated with novice-like views of knowledge and the valuing of certain and directly applicable knowledge. PBL students aimed at understanding, but also valued the role of memorization. Study IV investigated 12 PBL tutorial groups of students (n=116) studying microbiology and pharmacology in a medical school. The educational application was expected to support a deep approach to learning: Group members course grades in a final examination were related to the perceived functioning of the PBL tutorial groups. Further, the quality of cases that had been used as triggers for learning, was associated with the quality of small group functioning. New dimensions of study orientations were discovered. In particular, novel, finer distinctions were found within the deep approach component. In medicine, critical evaluation of knowledge appeared to be less valued than understanding and relating. Further, collaboration appeared to be closely related to the deep approach, and it was also important in terms of successful PBL studying. The results of the studies confirmed the previously found associations between approaches to learning and study success, but showed interesting context- and subgroup-related differences in this respect. Students ideas about the nature of knowledge and their approaches to learning were shown to be closely related. The present study expanded our understanding of the dimensions of study orientations, of their development, and their contextual variability in pharmacy and medicine.
