Abstract

This research aims to determine the effect of Evaluation of Prior Knowledge and Student Worksheets on Evaluation of Learning Outcomes and determine the difference in learning outcomes between high initial knowledge and low initial knowledge using the Project Based Learning model integrated with Generic Science Skills in Acid-Base material. This research has two independent variables, namely Initial Knowledge Evaluation and Learner Worksheet and one dependent variable, namely Evaluation of learning outcomes data. The population in this study were all class XI students of SMA Negeri 2 Kabanjahe consisting of 6 classes. The sample in this study was taken using a purposive sampling technique from 1 class, namely class. The instruments used are initial knowledge evaluation test instruments, learning outcome evaluation test instruments and Student Worksheets as well as non-test student observation sheets. Data were analyzed using multiple linear regression tests and Independent Sample T-Test. The results of data analysis show that there is a significant influence between the value of Prior Knowledge and Student Worksheets on learning outcomes and there is a significant difference in the value of learning outcomes between students whose initial abilities are classified as high and students whose initial abilities are classified as low.

Abstract

The FSLC (Formulate Share Listen Create) model is a cooperative learning approach. This study compares the FSLC model with crossword media to a conventional PowerPoint-based model and examines the correlation between students' learning outcomes and interest. The sample included 25 purposively selected students per class for experimental and control groups with similar backgrounds. Using a pretest-posttest control group design, the experimental class learned electrolyte and nonelectrolyte solutions via FSLC with crossword puzzles, while the control class used PowerPoint. Results showed higher average interest (86.60 vs. 80.40) and outcomes (83.30 vs. 79.70) in the experimental group, with F_calculated > F_table. A strong correlation was found between interest and outcomes in the experimental class (r = 0.931 > r_table = 0.396), with a determination index of 11%, indicating a positive relationship.
