Abstract

This study aims to determine the effect of discovery learning models on student learning outcomes in class VII heat material at SMP Negeri 2 Manduamas with quasi-experimental research methods and the population in the study, namely class VII SMP students with a total sample of 82 students. The sampling technique is Cluster Sampling. The instrument used was the test of learning outcomes in the form of multiple choice as many as 20. Before being given treatment to the two classes, the results obtained - the average pretest score for the experimental class was 49.63 and the average score for the control class was 49.44. After being given different treatments, the average posttest score for the experimental class was 74.26 and the average posttest score for the control class was 64.26. The results of the posttest data prerequisite test stated that the sample was normally distributed and homogeneous. Then, a one-sided t-test (a = 0.05) was performed with the condition that t count > t table or 4.13 > 1.67. So it can be said that there is a significant effect of discovery learning model on student learning outcomes in heat material for class VII SMP.

Abstract

This study investigates the scientific reasoning profiles of physics education students using Lawson’s Classroom Test of Scientific Reasoning (LCTSR). A descriptive quantitative design was employed with 50 undergraduate students from the Physics Education Study Program at Universitas HKBP Nommensen, Indonesia. The LCTSR instrument consists of 30 paired multiple-choice items assessing six dimensions of scientific reasoning: conservation reasoning, proportional reasoning, control of variables, probabilistic reasoning, correlational reasoning, and hypothetico-deductive reasoning. The results show that the mean LCTSR score was 12.4 out of 30, indicating that most students were at the transitional reasoning level. Specifically, 30% of students were classified as concrete reasoners, 56% as transitional reasoners, and only 14% as formal reasoners. Among the six reasoning aspects, conservation reasoning demonstrated the highest achievement (77.5%), whereas hypothetico-deductive reasoning was the weakest (16.7%). The findings indicate substantial difficulties in abstract reasoning processes. These results highlight the need for explicit instructional strategies to promote higher-order scientific reasoning in physics education programs.
