The development of learning achievement and critical thinking for biology 1 subject in chemistry of life of grade 10 students through context-based learning
Abstract:
The purpose of this research is to: 1) compare students learning achievement in Biology 1 between context-based learning and traditional learning, 2) compare students learning achievement in Biology 1 between pretest and posttest through context-based learning, 3) compare students learning achievement in Biology 1 through context-based learning with a 70 percent threshold, 4) compare students critical thinking in Biology 1 between context-based learning and traditional learning, 5) compare students critical thinking in Biology 1 between pretest and posttest through context-based learning, and 6) compare students critical thinking in Biology 1 through context-based learning with a 70 percent threshold. Cluster random sampling was conducted on two groups of grade 10 students from Suratthani School, consisting of 40 students in the experimental group and 38 students in the control group. The research instruments included lesson plans of the context-based learning approach, lesson plans for the traditional learning approach, a learning achievement test, and critical thinking abilities test. The data was statistically analyzed by mean, standard deviation and t-test for independent groups, dependent groups, and one-sample groups. The results indicate that: 1) the learning achievement in the posttest of grade 10 students for Biology 1 in the Chemistry of Life unit through context-based learning for the experimental group was higher than that of the control group using traditional learning, with statistical significance at the .05 level (p= .002); 2) the learning achievement in the posttest Biology 1 was higher than in the pretest, with statistical significance at the .05 level (p= .000); 3) the learning achievement in the posttest was higher than the 70 percent threshold, with statistical significance at the .05 level (p= .000); 4) the critical thinking in the posttest for Biology 1 in the Chemistry of Life unit through context-based learning for the experimental group was higher than that of the control group using the traditional learning, with statistical significance at the .05 level (p= .000); 5) the critical thinking in posttest for Biology 1 was higher than in the pretest, with statistical significance at the .05 level (p= .000) and 6) the critical thinking in the posttest was higher than the 70 percent threshold, with statistical significance at the .05 level.
