Abstract

This study was a quasi-experimental research. The aims of this research were to compare: 1) scientific problem solving ability of lower secondary school students between Teaching science by case-based learning with inquiry questions and Teaching science by using a traditional method. 2) Attitude towards science of lower secondary school students before and after science learning by case-based learning with inquiry questions. 3) Attitude towards science of lower secondary school students between Teaching science by case-based learning with inquiry questions and Teaching science by using a traditional method. The samples were Mathayom Suksa 3 students in Academic Year 2016. These samples were separates in two groups: the experimental group was learned science by case-based learning with inquiry questions and the comparative group was learned science by using traditional instruction. This research has two instruments for collecting data. First, the scientific problem solving writing test and the attitude towards science evaluation test. The collected data were analyzed by means of arithmetic mean, percentage, standard deviation and t-test. The research findings were summarized as follows: 1) The experimental group’s posttest mean scores of scientific problem solving score were higher than the comparative group at the significance level of .05; 2) The experimental group’s posttest mean scores of attitude towards science scores were higher than pretest mean scores at the significance level of .05; 3) The experimental group’s posttest mean scores of attitude towards science scores were not difference from the comparative group at the significance level of .05
