Abstract:

This research and development aimed to study, develop, and implement the constructivism learning object to enhance knowledge and critical thinking of undergraduate students.

The independent variable was the constructivism learning object and dependent variables were knowledge construction and critical thinking skill of the undergraduate students. The sample was 163 third year medical students of Suranaree University of Technology, derived from simple random sampling using Taro Yamane formula.

This research contained 4 phrases:
1) studied and analyzed basic knowledge and surveyed the opinion of 19 experts by DELPHI technique,
2) developed the constructivism learning object,
3) implemented the constructivism learning object with 163 undergraduates students of Suranaree University of Technology,
4) presented the constructivism learning object.

The research instruments were learning object media, survey form of opinion to learning object, knowledge construction test, critical thinking test, interview recording form. The data was statistically analyzed by percentage, mode, I.R., mean, standard deviation, inter-quartile range, and t-test of dependent group.

The research findings were as follow:
1. All of the experts agreed coincidently with the constructivism learning object (Median = 5, I.R. = 0.67) and agreed with the constructivism learning object in all components at the level of “most” (mean = 4.83). The constructivism learning object was composed of 6 steps; 1) state the problem, 2) study the problem, 3) solve the problem, 4) construct knowledge, 5) implementation, 6) evaluation.
2. The critical thinking skill of the students after studying with constructivism learning object was significantly higher than before studying at the level of .05.,
3. The level of elaboration was high at 28.57%.

Keywords:
