student involvement in class activities. In this study, involvement in class activities
significantly affects the problem-solving efficacy of students at two universities,
namely, University of Technology and University of Science. The research of
Bossert showed that student involvement in class activities promoted student
performances ( Bossert 1988 ). Specifically, recent meta-analyses suggested that
student involvement in class activities benefited students at all age levels, of all
subject areas, and for a wide range of tasks, such as those involving problem-solving
efficacy ( Johnson et al. 1983 ; Slavin 1983 ). In each university, in order to make a
policy for the instructional program and to select a teaching method or to evaluate
the studying result of the student, the experts or the program makers of VNU-HCM
should be notably concerned about this factor.

4 Conclusion

This study explored how learning experiences affect problem-solving efficacy of
Vietnamese college students' in technical and scientific areas. Results of this study
found that these contribute to fill in the literature gap of Vietnamese college stu-
dents' problem-solving efficacy development. The study also found that Vietnamese
college students' problem-solving efficacy was below high. Thus, the information
