This research aimed to discover appropriate learning management to suit students' different learning styles within a multicultural society at state-run universities using mixed methods research of explanatory design. A survey was first conducted followed by focus group discussions. It was found that the students consisted of all four types of learning styles: reflector, activist, theorist and pragmatist, while, reflectors were the majority group. The results also showed that students from different disciplines and types of high schools used different learning styles. However, the participants in the focus groups, especially the Muslim students, stated that they employed the pragmatic style as well as their dominant style. It is suggested that a teaching style incorporating practiced-based learning, such as lab-work, field work or project-based learning would suit all students. Student-centered classes and active leaning are also recommended as being appropriate for all types of student learning styles.

The purpose of this study was to examine the items and the dimensionality of a scale to measure professional commitment of teachers in Thailand. Data were collected by in-depth interview and questionnaire. The content analysis was conducted with the qualitative data for the purpose of item writing. Differential item functioning (DIF), exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and bi-factor CFA model analysis were conducted to establish validity evidence. As a result of EFA and CFA, the study showed that a 3-dimensional scale can effectively measure professional commitment of teachers, which was achieved by the 18-item measure. A polytomuos item response theory model was also fitted to estimate item parameters and to examine the test information function.
