Abstract [en]

In this study, we investigated why Laotian students had a low score, when they were tested by the Force Concept Inventory (FCI). About 400 first year university students answered the FCI or a Lao version of the FCI (LFCI) with the contexts of some questions changed. The students answered a questionnaire and 34 of the students were interviewed. The students found the FCI/LFCI questions difficult and the phenomena in some of the questions unfamiliar, for example questions about ice hockey. The results show that the low score cannot be explained by specific alternative conceptions and only to a very small part by unfamiliar context. The explanation seems to be that the students relied on everyday life experiences when they answered the questions.

Abstract [en]

This thesis reports about Laotian students’ understanding of the concepts of mechanics, and students’ activities when solving physics problems in groups. Totally, more than 1,000 first year university students from three universities in Laos have been tested using two versions of the Force Concept Inventory (FCI) over a period of three years. The Force Concept Inventory was developed in the USA to test students’ understanding of mechanics concepts. The contexts of some questions were unfamiliar for Laotian students and therefore another Laotian version was constructed. We found that Lao students obtained a low score on the FCI. The average scores of the post-test ranged from 21% to 26% over the three years. The introduction of the Laotian version resulted in just a small improvement of the score but it helped the students to read and understand the questions more quickly. It was difficult to perceive from the answers to the FCI if the students used alternative conceptions however, in video recordings it could be seen that some students did use well-known alternative conceptions. In many cases, students seemed to use their everyday life experiences to find the answers to the FCI questions instead of referring to physics concepts.

Group discussions were introduced in tutorial sessions for first year students. There were two types of group discussions. In the first type 29 groups solved end-of-chapter problems and three groups were recorded. One group described the physics theory of the problem before they selected equations and successfully solved the problem. Students in this group were not afraid to raise disagreements; they asked questions and took turns answering them which resulted in a fruitful discussion. The other two groups made the major mistake of not considering that the object moved with constant speed. Students suggested equations to use without giving any arguments based on physics theory. Both groups got stuck and needed help from the teacher. It was found that the problem solving strategy in the physics textbook did not include the important step of describing the physics theory and could actually encourage students to start looking for equations without first describing the physics.

In the second type of group discussions 52 groups discussed qualitative multiple-choice questions. Seven groups were recorded and 14 students and three teachers were interviewed. In the group discussions most students co-constructed an answer. However, the students in general did not seem to come to an understanding of the physics concepts and the follow-up discussion in class was essential for a better understanding. To improve the discussions, the students need more time and should also be taught about working in groups.

The thesis is concluded with a section on the implications for education in physics in Lao PDR.
