Abstract [en]

This paper presents the situation of physics teaching and learning at the Science Foundation Studies program at National University of Laos. The study has focused on the students' understanding of concepts in mechanics, and the situation of the laboratory work activities. The research tools used in this study were the Force Concept Inventory test, interviews and questionnaires. The results show that in an international comparison the Lao students reveal a low level of conceptual understanding in mechanics. They also show no improvement in their conceptual understanding after teaching. The students have little experience of laboratory work. They had expectations that laboratory work would be an interesting part of Physics Foundation Studies Course. However, few of the students do get involved in the actual measurements and handling of equipment during the practical activities. So, many of them do not feel that they learn much physics through laboratory work. This corresponds to their teachers' understandings as well. Some strategies for improving the above mentioned aspects of physics teaching based on physics education research will be suggested.

Abstract [en]

The aim of this thesis is to get a better understanding of the role of practical work in physics education in the Lao People’s Democratic Republic (Lao PDR). The Lao PDR is one of least developed countries in the world with a weak base for science, and poor market opportunities for science graduates. The rapidly expanding educational system has many problems concerning quality of the infrastructure and staff competence.

A combination of qualitative and quantitative methods was used in the study in order to assure reliability of the results. Data was collected through questionnaires, interviews, video-recordings, and my own ethnographic experiences of working in the Lao educational system for more than thirty years. The study was informed and results analysed with help of curriculum perspective and Cultural-Historical Activity Theory (CHAT).

The findings show that Lao physics education curriculum at all levels is dominated by very traditional forms of teaching with an almost total absence of practical. Official curricular documents have statements prescribing teachers to do practical work in high school and university courses. However, few institutions have functioning equipment and skilled teachers for organising practical activities. Therefore, the majority of Lao students come to university and even can finish university without experience of practical work in physics. This shows the gap that exists between intended and implemented curricula. The majority of the students understand the importance of having practical activities in physics. However, after being exposed to laboratory experiments in an introductory physics course, they expressed criticism about the quality of instruction and the process of the practical work organisation. The laboratory group work analysis showed that discussions were mainly focused on understanding the experimental procedures, manipulating equipment, and collecting data for the report rather than on the physics content (object of activity, in CHAT terms).

Based on the research results, it is possible to suggest that a systemic approach is needed to stimulate the development of a new practical work culture in schools and universities. This approach should include training and incentives for science teachers, development of assessment strategies including practical work, maintenance structures for physics equipment, and technical support for the organisation of demonstrations and laboratory exercises.

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.
