Abstract:
The purposes of this research were aimed to : 1) develop science process skills of
students in Pratomsuksa IV using the constructivist teaching approach, and 2) compare the
science process skills of these students before and after the experiment using the constructivist
teaching approach. The sample of this study selected through simple random sampling consisted
of 28 students in Pratomsuksa IV, or grade 4, at Wat Nongwan School under Chanthaburi
Educational Service Area I. The research instruments used in this study included : (1) 26 lesson
plans designed for the constructivist teaching approach, and (2) a science-process-skills test.
Statistical analysis was employed using mean score, percentage, standard deviation, and t-test for
dependent sample.
The following results were shown. 1) Individual science process sub-skill of students in
Pratomsuksa IV were developed after the experiment studying through the constructivist teaching
approach. The Inferring and Calculating sub-skills were the highest and lowest respectively
for the students development on their science process skills. 2) After the students in Pratomsuksa
IV had learned their lessons through the constructivist approach, their mean scores of the science
process skills became significantly higher than those before the experiment at the 0.05 level.
