Comparison of Children Learning in Science Model with Direct Instruction in Developing Critical Thinking Skills in Terms of Learning Motivation in Science Learning

Comparison of Children Learning in Science model with Direct Instruction in the development of critical thinking skills in learning science in elementary school. The purpose of this study was to determine the comparison of children Learning in Science with Direct Instruction in the development of critical thinking skills in terms of learning motivation in learning science in elementary school district Kedawung-Sragen, this study is a quasi-experimental research, using quantitative data analysis and sampling using cluster random sampling. Data collection is by test. The research Data were analyzed by stages: prerequisite analysis test, variance analysis test of two unequal cell paths, and further analysis of variance test. The results of the test calculation of variance analysis of two unequal cell paths obtained data that Fcount (75.61) > Ftable (3.89), and in further tests Anava, obtained data that the marginal mean of Children Learning in Science model is 89.78 greater than the Direct Instruction model which has an average of 77.66. The conclusion of the study is that the model of children Learning in Science is more effective than the model of Direct Instruction in the development of critical thinking skills.

Comparison of Problem-Based Learning Model with Direct Instruction in Mathematics Learning Towards the Development of Critical Thinking Skills

The selection and application of learning models to develop critical thinking skills is a problem in learning mathematics in elementary schools. The purpose of this study was to determine the difference between Problem Based Learning model and Direct Instruction model in mathematics learning on the development of critical thinking skills. This research is a quasi – experimental research, using quantitative data analysis and sampling using cluster random sampling. Data collection with tests. Data analysis of this research includes: prerequisite analysis test, two-way variance analysis test of unequal cells, and further analysis of variance test. The results of the calculation of the analysis of variance test of two-way unequal cells obtained data that Fcount (5.36) > Ftable (3.91), and in the Anava further test, obtained data that the marginal mean of the Problem Based Learning model is 88.58 greater than the Direct Instruction model which has a mean of 80.05. The conclusion of the research is that the effectiveness of the Problem Based Learning model is better than the Direct Instruction model in developing critical thinking.
