| Abstract (EN) |
Mathematics is fundamental knowledge that students can adopt on a regular basis
as well as in future careers. It also allows students to think systematically and
rationally, enhancing problem-solving skills (OECD., 2023). The current research
aimed to 1) analyze multilevel mediating effects of teacher training and extension
courses on the relationships among teacher support, motivation, and self-efficacy
in mathematics. 2) study instruction to enhance motivation and self-efficacy in
mathematics. Secondary data were adopted from PISA 2022, in the study of 6,196
students in Thailand who studied in 280 schools of all types. The data were then
analyzed using MSEM by the Mplus program. The results revealed that the
structural equation model of multilevel mediating effects of teacher training and
extension courses on the relationships among teacher support, motivation, and
self-efficacy in mathematics had a good fit with the empirical data. The statistical
values were (χ2(1, N=6196)=3.48, p=0.062, CFI=0.997, TLI=0.980,
RMSEA=0.020). The student-level model had full mediation in which teacher
support had an indirect effect via motivation with a statistical significance of .05
and motivation had a direct effect on self-efficacy with a statistical significance of
.05. In the school-level model, it was discovered that teacher training and
extension courses had a direct effect on self-efficacy and motivation with no
statistical significance of .05 and the participants of all instructions had higher
averages for motivation and self-efficacy than those of non-participants. |
