A Modeling study about barriers which anatolian teacher training school physics teacher faced implementing micro-computer based laboratory

Alptekin, Funda
The aim of this study is fourfold: (a) to explore the barriers Anatolian Teacher Training High School (ATTHS) physics teachers face with implementing Microcomputer Based Laboratory (MBL), (b) to develop two structural equation models (SEM) and a hierarchical linear model (HLM) to determine relationships between these barriers, (c) to describe how MBL is being implemented in ATTHS physics courses and (d) Make suggestions for an effective in-service training course for MBL. A total of fifteen questionnaires were sent to 196 ATTHS with an accessible population of 196 principals, 239 physics teachers and 5880 students. With the aid of descriptive statistics the results of the needs assessment survey were examined. The result of the models, literature review and in-service training course needs assessment were connected. None of the teachers stated that they have negative attitude toward any of the attitudes. They stated that second order barriers have smaller effects than first order barriers. Many of the teachers stated that lack of resources is the main problem, and SEM showed that lack of resources is the problem which affects most. Institutional issues directly affect lack of resources and the direct effect of attitudes is small on MBL integration. Students' attitudes also have a small direct effect on MBL integration. Students' MBL proficiency has a high direct effect on MBL integration. When HLM results were examined, none of the teacher factors affected the desire of students to use MBL. Only two student factors affected the desire of students to use MBL; attitude toward use of technology and attitudes toward the physics course. Moreover need analysis showed that the teachers mainly prefer in-service courses in their home cities, and they prefer in-service courses for all topics. They do not prefer their colleagues at instructors on in-service courses.
