Abstract

This research aims to determine the effect of implementing E-LKPD based on Integrated Problem Based Learning (PBL) Micro Scale Lab on learning outcomes and attitudes towards chemistry in class XI colloid materials at SMAN 6 Mataram. The method used is a quasi-experimental method with a non-equivalent control group design. The sampling technique used is purposive sampling, where the researcher deliberately selects samples for certain reasons. The total population in class XI MIPA is 99 people. The number of samples in this study was 68 students in class XI MIPA 1 consisting of 34 students as the experimental class and class XI MIPA 2 consisting of 34 students as the control class. This research used a quantitative research approach. Data analysis was carried out using the normality test, homogeneity test, and hypothesis test (t-test) at a significance level of 0.05 or 5%. The results of the t-test obtained a value of rcount < rtable, namely 0.012 < 0.05, so it can be concluded that the application of the problem based learning model integrated with micro scale lab has a positive effect on student learning outcomes and attitudes towards chemistry at SMAN 6 Mataram in class XI colloid material.

Abstract

This research aims to develop an electronic Student Worksheet (e-LKPD) based on Google Sites that integrates the local culture "Njeleng" into the subject matter of the nature and introduction of chemistry. The development of this learning media is expected to increase students' interest and understanding of chemistry through a contextual and cultural approach. The research method employed is the four-D (4D) model consisting of the stages of needs analysis, design, development, and product evaluation. The developed e-LKPD product was tested on students and validated by experts to determine its validity and practicality. The results indicated that the Google Sites-based e-LKPD with the integration of "Njeleng" culture achieved an average validity score of 0.78, demonstrating that the media is valid as a teaching resource. Additionally, practicality tests showed an average score of 80%, indicating ease of use by both teachers and students during the learning process. The incorporation of local culture as a learning context adds value in cultural preservation while enriching students' learning experiences. Therefore, this e-LKPD is recommended as an innovative and relevant alternative learning media tailored to student characteristics, capable of enhancing enthusiasm and comprehension of basic chemistry concepts.

Abstract

This research is the quasi-experimental research that aimed to know the influence of collaborative learning model assisted by flash card media on student numeracy skills on the material of basic laws of chemistry at SMAN 7 Mataram. The population in this study were all students of class X SMAN 7 Mataram as many as 11 classes totaling 396 people, while the sample of this study were class X-K as an experimental class totaling 34 people and class X-I as a control class totaling 36 people with the selection of samples by purposive sampling. The results of the analysis of the improvement of student numeracy skills obtained the average score of N-Gain in the experimental class 0.75 classified as high category and the control class 0.60 classified as moderate category. Based on the results of the t-test analysis, the Sig. (2-tailed) value is 0.000 < 0.05, then H0 is rejected and Ha is accepted. The results of this study can be concluded that the use of collaborative learning models assisted by flash card media has an effect on improving student numeracy skills on the material of basic laws of chemistry at SMAN 7 Mataram.
