The association of faculty's teaching philosophy and teaching behaviour, and critical thinking and self- direction in learning

The intent in this study was to investigate in what ways teachers· beliefs about education and teaching are expressed in the specific teaching behaviours they employ, and whether teaching behaviours, as perceived by their students, are correlated with students· critical thinking and self-directed learning. To this end the relationships studied were: among faCUlty members· philosophy of teaching, locus of control orientation, psychological type, and observed teaching behaviour; and among students· psychological type, perceptions of teaching behaviour, self-directed learning readiness, and critical thinking. The overall purpose of the study was to investigate whether the implicit goals of higher education, critical thinking and self-direction, were actually accounted for in the university classroom. The research was set within the context of path-goal theory, adapted from the leadership literature. Within this framework, Mezirow·s work on transformative learning, including the influences of Habermas· writings, was integrated to develop a theoretical perspective upon which to base the research methodology. Both qualitative and quantitative methodologies were incorporated. Four faCUlty and a total of 142 students participated in the study. Philosophy of teaching was described through faCUlty interviews and completion of a repertory grid. Faculty completed a descriptive locus of control scale, and a psychological type test. Observations of their teaching behaviour were conducted. Students completed a Teaching Behaviour Assessment Scale, the Self-Directed Learning Readiness Scale, a psychological type test, and the Watson-Glaser Critical Thinking Appraisal. A small sample of students were interviewed. Follow-up discussions with faculty were used to validate the interview, observation, teaching behaviour, and repertory grid data. Results indicated that some discrepancies existed between faculty's espoused philosophy of teaching and their observed teaching behaviour. Instructors' teaching behaviour, however, was a function of their personal theory of practice. Relationships were found between perceived teaching behaviour and students· self-directed learning and critical thinking, but these varied across situations, as would be predicted from path-goal theory. Psychological type of students and instructor also accounted for some of the variability in the relationships studied. Student psychological type could be shown as a partial predictor of self-directed learning readiness. The results were discussed in terms of theory development and implications for further research and practice.

Sobre cómo los docentes podrían incentivar la comprensión crítica de los estudiantes de primaria

Una preocupación por el valor formativo de las imágenes que nos circundan y la laguna al respecto que muestra la educación formal española nos puso en marcha para realizar una investigación doctoral. Así que nos propusimos: 1. Estudiar la relación entre dos ámbitos que se ocupan del estudio y la producción de imágenes: la Educación Artística y la Educación Mediática. Mediante un análisis pormenorizado de las investigaciones y experiencias más relevantes que nos permitieron evidenciar el papel que los medios juegan en la Educación Artística y el que las artes juegan en la Educación Mediática. Indagar en el modo en el que la Educación Artística (en adelante E.A.) pudiera incidir en la Mediática (en adelante E.M.) mediante una prueba experimental, en un entorno educativo eal, con el fin de desarrollar la comprensión crítica de los estudiantes

Crear un material audio-visual. Mejorar la calidad de la enseñanza. Estudiar la aplicación de programas audio-visuales en el aula. Buscar una metodología adecuada a la utilización didáctica de los medios audio-visuales. Comprobar las diferencias que pueden existir entre diferentes medios audio-visuales, diapositivas-vídeo. La muestra está formada por los niños de tres aulas de segundo de BUP del Colegio Escoles Pies de Sarrià (Barcelona). En total 102 sujetos que han estudiado primero de BUP en el mismo centro. Se expone el marco teórico. Se describen las variables (medios audio-visuales, rendimiento escolar, rendimiento escolar anterior, metodología, inteligencia, clase social, profesor y edad). Se describe la muestra. División de la muestra en tres clases (sin medio audio-visual, con vídeo, con diapositivas). Realización del material audio-visual. Se realizan las sesiones pertinentes en cada clase. Aplicación de la prueba objetiva. Se analizan los datos. Se ofrecen conclusiones y alternativas. Prueba objetiva de rendimiento. Test d'aptituds diferencials. Baremo de puntuaciones anteriores. Diferencia de medias, estadística descriptiva, análisis de varianza, prueba de Scheffe, para establecer si hay diferencias entre el grupo que ha trabajado con medio audio-visual, visual y sin medio audiovisual. La metodología experimental aplicada no ha producido los resultados esperados, hay razones para afirmar que han intervenido factores no controlados, ajenos a la experimentación. Se constata un gran interés de los alumnos por el uso del vídeo como elemento de motivación. Se señala la importancia de incidir en este campo creando metodologías activas adecuadas y series de programas válidos. Hace falta una intensa investigación en las posibilidades y efectos de dichas metodologías.

Filmljudets funktioner i krigsfilm : En audio-visuell analys av Apocalypse Now och Saving Private Ryan

I denna uppsats har filmljudet i krigsfilmerna Apocalypse Now och Saving Private Ryan undersökts. Detta har gjorts för att försöka bidra med ökad förståelse för filmljudets användningsområde och funktioner, främst för filmerna i fråga, men även för krigsfilm rent generellt. Filmljud i denna kontext omfattar allt det ljud som finns i film, men utesluter dock all ickediegetisk musik. Båda filmerna har undersökts genom en audio-visuell analys. En sådan analys görs genom att detaljgranska båda filmernas ljud- och bildinnehåll var för sig, för att slutligen undersöka samma filmsekvens som helhet då ljudet och bilden satts ihop igen. Den audio-visuella analysmetod som nyttjats i uppsatsen är Michel Chions metod, Masking. De 30 minuter film som analyserades placerades sedan i olika filmljudzoner, där respektive filmljudzons ljudinnehåll bland annat visade vilka främsta huvudfunktioner somfilmljudet hade i dessa filmer. Dessa funktioner är till för att bibehålla åskådarens fokus och intresse, att skapa närhet till rollkaraktärerna, samt att tillföra en hög känsla av realism och närvaro. Intentionerna med filmljudet verkade vara att flytta åskådaren in i filmens verklighet, att låta åskådaren bli ett med filmen. Att återspegla denna känsla av realism, närvaro, fokus samt intresse, visade sig också vara de intentioner som funnits redan i de båda filmernas förproduktionsstadier. Detta bevisar att de lyckats åstadkomma det de eftersträvat. Men om filmljudet använts på samma sätt eller innehar samma funktioner i krigsfilm rent genrellt går inte att säga.I have for this bachelor’s thesis examined the movie sound of the classic warfare movies Apocalypse Now and Saving Private Ryan. This is an attempt to contribute to a more profound comprehension of the appliance and importance of movie sound. In this context movie sound implies all kinds of sounds within the movies, accept from non-diegetic music. These two movies have been examined by an audio-visual analysis. It's done by auditing the sound and picture content separately, and then combined to audit the same sequence as a whole. Michel Chion, which is the founder of this analysis, calls this method Masking. The sound in this 30 minute sequence was then divided into different zones, where every zone represented a certain main function. These functions are provided to create a stronger connection to the characters, sustain the viewers interest and bring a sense of realism and presence. It seems though the intention with the movies sound is to bring the viewers to the scene in hand, and let it become their reality. To mirror this sense of realism, presence, focus and interest, proves to be the intention from an early stage of the production. This bachelor’s thesis demonstrates a success in their endeavours. Although it can’t confirm whether the movie sound have been utilized in the same manner or if they posess the same functions to warefare movies in general.

Audiovisuella loopar och kollektiv live-looping

 Loop-teknik i solistiska sammanhang är en idag väletablerad musicerande form dock är möjligheterna att använda tekniken i ensembleform ett mer eller mindre oprövat fält. I projektet “Audiovisuella loopar” som genomförts vid Högskolan Dalarna presenteras ett system för kollektiv livelooping där upp till fyra personer loop-musicerar tillsammans och där loopandet samtidigt kan spelas in och spelas upp som videoklipp. Tekniken har visat sig ha en stark kreativ potential. Med enbart en kort instruktion så startar en kollektiv process där den omedelbara feedbacken ger ett “fl ow” som lockar fram skaparglädjen hos musikanterna. Dessa erfarenheter pekar på spännande möjligheter att använda tekniken i musikundervisning och musikterapi.

Action research in higher education : the advancement of university learning and teaching

This thesis aims to contribute to the improvement and advancement of university learning, teaching, and staff development; to integrate educational theory and the practice of university teaching; and to contribute to the establishment of a new, emerging paradigm in higher education. The strategy towards achieving these aims comprises (1) an alternative research methodology in the interpretive, non-positivist paradigm; (2) an integrated framework drawing on a variety of previously unrelated theories to form an alternative model of university education; and (3) reference to the dialectical relationship between educational theory and teaching practice and their integration through action research in higher education. The thesis is not so much a critique of the traditional paradigm and of existing functionalist-structuralist approaches to higher education, but more a development and clarification of an alternative, dialectical, human action approach to higher education. The original contribution of this thesis to the theory and practice of higher education lies in the development (1) of an alternative model of university education based on an integration of previously unrelated domains of theory; (2) of a theoretical model of professional development as action research (the CRASP Model: Critical attitude, Research into teaching, Accountability, Self-evaluation, Professionalism); and (3) of action research projects in higher education. Action research is research by the university teachers themselves into their teaching practice, i.e. into problems of the curriculum and student learning. The case studies included in and appended to this thesis show that in one educational setting at least it was possible to improve and advance university learning and teaching through action research. The evidence for this advancement is provided in a number of previously published case studies compiled in the Appendix.

User-centered design and evaluation of an interactive visual-haptic-auditory interface : a user study on assembly

Utilizing user-centred system design and evaluation method has become an increasingly important tool to foster better usability in the field of virtual environments (VEs). In recent years, although it is still the norm that designers and developers are concerning the technological advancement and striving for designing impressive multimodal multisensory interfaces, more and more awareness are aroused among the development team that in order to produce usable and useful interfaces, it is essential to have users in mind during design and validate a new design from users' perspective. In this paper, we describe a user study carried out to validate a newly developed haptically enabled virtual training system. By taking consideration of the complexity of individual differences on human performance, adoption and acceptance of haptic and audio-visual I/O devices, we address how well users learn, perform, adapt to and perceive object assembly training. We also explore user experience and interaction with the system, and discuss how multisensory feedback affects user performance, perception and acceptance. At last, we discuss how to better design VEs that enhance users perception, their interaction and motor activity.

Calibration of audio-video sensors for multi-modal event indexing

This paper addresses the coordinated use of video and audio cues to capture and index surveillance events with multimodal labels. The focus of this paper is the development of a joint-sensor calibration technique that uses audio-visual observations to improve the calibration process. One significant feature of this approach is the ability to continuously check and update the calibration status of the sensor suite, making it resilient to independent drift in the individual sensors. We present scenarios in which this system is used to enhance surveillance.

Supporting culturally and linguistically diverse students during clinical placement: strategies from both sides of the table

Background: Increasing proportions of Culturally and Linguistically Diverse (CALD) students within health professional courses at universities creates challenges in delivering inclusive training and education. Clinical placements are a core component of most health care degrees as they allow for applied learning opportunities. A research gap has been identified in regard to understanding challenges and strategies for CALD students in health professional placements.

Methods: A key stakeholder approach was used to examine barriers and enablers experienced by CALD students in clinical placement. Semi-structured focus groups with healthcare students (n = 13) and clinical placement supervisors (n = 12) were employed. The focus groups were analysed using open coding and thematic analysis.

Results: Three main barrier areas were identified: placement planning and preparation; teaching, assessment and feedback; and cultural and language issues. Potential solutions included addressing placement planning and preparation barriers, appropriate student placement preparation, pre-placement identification of higher risk CALD students, and diversity training for supervisors. For the barrier of teaching, assessment & feedback, addressing strategies were to: adapt student caseloads, encourage regular casual supervisor-student conversations, develop supportive placement delivery modes and structures, set expectations early, model the constructive feedback process, use visual aids, and tailor the learning environment to individual student needs. The enablers for cultural & language issues were to: build language and practical approaches for communication, raise awareness of the healthcare system (how it interacts with healthcare professions and how patients access it), and initiate mentoring programs.

Conclusions: The findings suggest that teaching and learning strategies should be student-centred, aiming to promote awareness of difference and its impacts then develop appropriate responses by both student and teacher. Universities and partnering agencies, such as clinical training providers, need to provide an inclusive learning environment for students from multiple cultural backgrounds.

Crenças sobre compreensão oral em língua estrangeira de alunos concluintes de um curso de Licenciatura em Letras

In this article we present and discuss a number of beliefs about listening comprehension among students who were in their last year of a teachers’ certification Letters course in Italian and Portuguese. The data were collected by means of questionnaires answered by all the participating students, logs and interviews conducted with five of the participating students, classroom observation, lessons recorded on audio and video, and diaries. The study is supported by a rationale on beliefs and on definitions of listening comprehension as a skill. The analysis indicate that a number of students showed lack of motivation and low expectations about developing oral comprehension skills due to several drawbacks in foreign language learning during their teacher education course. However, other beliefs that emerged from the data, such as the importance of visual aids to help understanding an oral text, seem to have a positive effect towards a satisfactory proficiency level in oral comprehension.
