Abstract

This research was carried out to determine the effect of implementing the crossword puzzle strategy on students learning motivation un theme 1 subtheme 1 learning 3 class V SDN 060927 Medan.the population in this study was 54 students consisting of class V students. The sample in the study used was simple random sampling which is a random sampling technique without playing attention to the similaritis in the population. Data was collected using a questionnaire and strenghened using the test questions provided, and the research was carried out using a quasi experimental design. The result obtained in this research show that the applicationof the crossword puzzle strategy has a significant influence on the learning motivation of students at SD 060927 Medan. The average obtained from the postest score in the experimental class and control class shows that the postest score in the experimental class is greater than the postest score in the control class, namely 88,33 > 73,56. Meanwhile, in the research hypothesis, the resulting t count value is greater than t table , namely 14,84 > 2.00. so that the application of the crossword puzzle strategy can have an influence on the learning motivation of students at SDN 060927 Medan.

Abstract

Salt hydrolysis instruction presents persistent challenges in promoting active participation and conceptual understanding among chemistry students. This study aimed to improve the learning activity and conceptual understanding of 26 Grade XI science students at SMA IT Al Fityah Pekanbaru through the ICARE learning model. A collaborative classroom action research design was implemented across two cycles, each comprising two meetings and the stages of planning, action, observation, and reflection. Data were collected through observation sheets assessing teacher and student activities, documentation, evaluations conducted after each meeting, and conceptual understanding tests administered at the end of each cycle. The data were analyzed descriptively using activity percentages, individual scores, class mastery rates, and achievement across seven indicators of conceptual understanding. The numbers of students who did not meet the mastery criterion and the lowest scores in each cycle were also examined to assess the distribution of learning outcomes. Instructional improvements emphasized participation, group discussion, reflection, and independent application of concepts. Student learning activity increased from 64.47% in Cycle I to 76.68% in Cycle II, representing an increase of 12.21 percentage points. The mean conceptual understanding score rose from 76.35 to 88.08, while the mean class score increased from 76.34 to 88.27. Class mastery improved from 69.22% to 88.46%. By Cycle II, all seven conceptual understanding indicators had reached at least 84.62%, with the ability to restate concepts reaching 100%. These findings demonstrate that ICARE can improve students’ engagement and conceptual understanding of salt hydrolysis. The model therefore offers a viable student-centered approach to chemistry instruction, provided that teachers ensure effective time management, reinforce prerequisite concepts, and distribute participation equitably.
