Abstract

This study aimed to determine the effectiveness of science worksheets with cognitive conflict strategies to reduce student heat misconceptions. This research was conducted at SMP Negeri 1 Lamongan by using one group pretest-posttest design. The data obtained in this study is quantitative data, and the number of students in VII grade is 50, students are called to complete the research if the proportion of correct answers is more significant than the standard achievement test. While the class is said to complete the study if 85% of students can reach the standard test criteria. The researcher obtained information about the level of mastery of students' concepts by using N-gain, one method in the descriptive qualitative analysis. It shows the different levels of student mastery before and after treatment given. The effectiveness of the Science Worksheet will be analyzed from the acquisition of learning outcomes. This yields 0.94 points which means that the value of N-Gain is in the sufficient category, it can be said that the application of the Science Worksheet with cognitive conflict strategies can reduce heat misconceptions of junior high school students.

Abstract

Teacher - center method more widely used in the learning process but knowledge gained students less than the maximum. Therefore, The researcher intended to carry out the process of learning that guides the students discover the concept through their own behavior so that the results are more meaningful and is expected to increase the achievement. This research aimed to describe the effect of the application of Guided Discovery model to the students’ achievement, both affective (scientific attitude), psychomotor, and cognitive, as well as to determine the linkages between these aspects. This research was designed using "True Experimental Design" conducted at SMP Negeri 1 Pucuk. The data obtained was the pre-test, post-test, and scores of psychomotor and affective abilities. Furthermore, the data were analyzed with statistical consisting of normality test, homogeneity, and hypothesis testing, and regression and correlation analysis. Post-test results were analyzed by t-test. T-test results obtained by the two parties –t­table t ttable shows the differences between control and experimental class. The t-test results obtained by the right parties  tcalculation≥ ttable (α= 0.05) showed that results for students in the experimental class is better than the control class. It can be concluded that the application of Guided Discovery model can improve the students’ achievement in the material of motion in SMP Negeri 1 Pucuk. The increase in value of the students’ psychomotor and affective effect on the increase in value of the students’ cognitive.
