Abstract

This study aims to determine the effect of inquiry learning model on student physics achievement in junior high school. The method used is experimental research. The sample used are; grade VII-D students as many as 27 people as control class, and level VII-G as many as 27 people as experimental class. The sample selection was done by purposive sampling technique. The data were collected by pre-test and post-test in both classes. The average pre-test in the experimental class is 28.04 and 30.11 for the control class. The average post-test score in the experimental class is 74.41 and 69.26 for the control class. The analysis result using t-test obtained t-test of 1.82 and t-table is 1.67. The value of t-test is greater than t-table at 5% and dk is 52. We conclude that there has been a significant influence of inquiry learning model on physics learning achievement.

Abstract

This research aimed to know there is or no effect of learning based phenomena model toward student’s conceptual understanding at SMAN 1 Kopang. The kind of this research was experimental research. Design of this research used Posttest Only Control Design with population was all of students at SMAN 1 Kopang. Sample of this research consist of two classes that is class X-1 asw control group and class X-2 as experimental group which used random sampling technique. Based on homogeneity and normality test showed that both of data was normal distribution. The data analysis used t-test. The result of t-test was 6,12 and t-table was 2,00, so Ha was accepted. The result of this research showed that there is effect of learning based phenomena model toward student’s conceptual understanding at SMAN 1 Kopang.

Abstract

The research is aimed to find out the influence of Problem Based Learning toward students’ learning motivation and concept understanding at the VIII grade students of SMPN 2 Tanjung. The type of this research is Quasi-Experiment in which the researcher uses pretest-postest control group design. The population of this research is the whole VIII Grade students of SMPN 2 Tanjung which consists of 124 students. Simple random sampling was used to take the sample from the number of population. Two classes of the VIII Grade students were taken as the sample of the research. The two classes are VIIIB and VIIIC classes that each class consists of 30 students. Collecting the data needed in the study, the researcher uses test as the main instrument to collect the data needed in this study. The collected data of the research in analyzed by using statistical analysis method, t-test in particular. The result of data analysis shows that the t-test for students’ learning motivation is 2.318 and the value of t-table is 2,002 meanwhile the result of t-test for students’ concept understanding is 4.152 and the value of t-table is 2.002 at the level of significance 5%. It means that the result of t-test is higher than the value of t-table. It can be interpreted that the alternative hypothesis ( ha ) is accepted and the null hypthesis (ho) is rejected. Finally, the study concluded that there is significant influence of Problem Based Learning towards students’ learning motivation and concept understanding at the VIII Grade students’ of SMPN 2 Tanjung.
