Abstract

The research aims to develop integrated teaching materials with a STEM approach to enhance students' scientific literacy, explicitly focusing on Basic Chemical Law Materials. The study utilized a Research and Development (R&D) approach employing the 4D (define-design-development-disseminate) research model. The research instruments included a test to measure students' scientific literacy and a non-test instrument to gather validation data from experts and assess student responses. The findings demonstrated high feasibility percentages, with 91.4% for content, 89% for presentation, 93.2% for language, 86.6% for scientific literacy, 93.2% for STEM, and 90% for media. Moreover, based on the scientific literacy test results, the N-gain pre-test and post-test indicated a substantial increase with a score of 0.74, classifying it as a high increase. Consequently, it can be concluded that developing integrated teaching materials with a STEM approach effectively enhances students' scientific literacy in basic laws of chemistry.

Abstract

This study aims to develop an initial ability test instrument based on science generic skills in the form of a scholastic test and develop a final chemistry evaluation test instrument in the topic of thermochemistry as well as find out the validity of the content and construction validity of the instrument. Research and development research, with a 4D development model consisting of 4 main stages, namely: Define, Design, Develop and Disseminate, due to time constraints this research was only up to develop. The results of the content validity test by experts obtained an average percentage of material aspects, namely 87.08%, construction aspects, namely 90.41%, language aspects, 92.5% and additional rules, 96.67%, so the question instrument is suitable for use. Based on the construction validation test data, it was found that of the 20 questions on the scholastic potential test tested, there were 19 questions that were valid and considered appropriate, while 1 other item was invalid, while of the 20 questions on the chemistry test tested, there were 17 questions that were valid and considered feasible, leaving 3 questions other invalid. For further research, it is hoped that this instrument can be implemented.

Abstract

This research aims to determine the analysis of the feasibility level and response of students to SAC (Smart Apps Creator) media integrated with project based learning on reaction rate material. The research method used is Research and Development with a 4D development model approach (define, design, development and disseminate). Research data collection is carried out by interviews and questionnaires or questionnaires that are distributed to teachers and students. This research was conducted at SMAS PAB 8 Saentis. The population and samples in this study are chemistry lecturers, teachers and students of grade XI 2 for the 2023/2024 academic year taken by purposive sampling of 30 people. Based on validity, it shows that the SAC learning media developed was declared valid by validators with the criteria of "Very Feasible" with an average validation score of 89.86%, then based on the results of student responses, it was obtained that the SAC learning media developed as a whole received an average percentage result of 83.81% with the criteria of "Strongly Agree". Therefore, SAC learning media integrated with the project-based learning model on the reaction rate material is suitable for use as a learning medium.

Abstract

The reading and writing habits of SMAN 2 Percut Sei Tuan students are relatively low. Therefore, students' literacy and high order thinking abilities are also relatively low. The implementation of scientific literacy-based learning strategies in the form of making summaries at the end of the learning process is expected to improve students' literacy and high order thinking skills. The instruments used are tests in the form of varied multiple choices and essays totaling 8 and 2 questions. The results of data analysis show that students' initial abilities on the 9 of HOTs-Literacy indicators are very low with an average value of 28.49. The summarizing treatment at the end of the learning process succeeded in improving the ability of HOTs-Literacy students in indicators (1) identifying information and data, (2) using information and data, (3) producing explanatory models, (4) distinguishing questions that can be researched scientifically, (5) formulating hypotheses, (6) making predictions, (7) analyzing data, (8) interpreting data, (9) drawing or presenting conclusions, respectively 63.7 ; 66.7; 68.4 ; 64.0 ; 70.9 ; 70.8; 79.2 ; 81.4 and 86.3 %.

Abstract

This research aims to find out whether the Guided Inquiry learning model is better than Discovery Learning in improving scientific literacy activities and student learning outcomes on reaction rate material. The research method used is quasi experimental. The sample from this research consisted of two classes, namely experimental class I which was taught using the guided inquiry learning model, totaling 29 students and experimental class II, which was taught using the Discovery Learning model, totaling 27 students. The results of data analysis show that the average learning outcomes of students using Guided Inquiry (80.69) are higher than the average learning outcomes of students taught using the Discovery Learning model (74.63) and the average scientific literacy activities of students using Guided Inquiry (79.15 ) higher than the average using the Discovery Learning model (73.72). Hypothesis results using the right-hand t-test and α = 0.05 obtained tcount > ttable (2.34 > 1.675) for students' scientific literacy activities and tcount > ttable (2.49 > 1.675) for student learning outcomes so that in this study the null hypothesis (Ho) is rejected and the alternative hypothesis (H₂) is accepted. Thus, it was found that the Guided Inquiry learning model was better than Discovery Learning in improving scientific literacy activities and student learning outcomes on reaction rate material.

Abstract

The aim of this research is to analyze students' needs for computational chemistry-based learning media on atomic structure and chemical bonding in the Basic Chemistry course. The population of this study were the first grade students of the Chemistry Department, FMIPA Unimed. The number of samples in this study was 93 students from three classes. The instruments used are multiple choice questions and questionnaires to determine mastery of atomic structure and chemical bonding. The research results show that the average score is 34.430 (poor category). The average score achieved in atomic structure material was 33.16 (very poor). The lowest score achieved in the atomic properties sub-material was 9.3. The average score achieved in chemical bonding material was 36.1 (very poor). The lowest score achieved in the properties of ionic compound sub-material was 17.5. The results of the questionnaire showed that the atomic structure material that students considered the most difficult was the wave mechanics atomic model at 72.233 (quite difficult), while for chemical bonding material it was the octet and duplet rule at 71.055 (quite difficult).

Abstract

This study aims to analyze the feasibility of using Lectora inspire learning media based on BSNP criteria; the effect of the discovery learning model on learning outcomes and learning outcomes; and the correlation between motivation and learning outcomes with the discovery learning model using the learning media Lectora inspire. This research is development research using adaptation measures in the ADDIE approach. The research in the implementation phase of using Lectora inspire learning media was carried out with Pre-Experiment Designs in the form of One-Group Pretest-Posttest Designs. The sample selection used a purposive sampling technique. The sample studied was 41 students from SMA Negeri 7 Medan. The instruments used were student learning outcomes tests, modified BSNP questionnaires, and student learning motivation questionnaires. The results of this study indicate that through the development of learning with Lectora inspire learning media using discovery learning models on chemical bonding materials: the average feasibility of using Lectora inspire learning media on all BNSP criteria is a very feasible category (content feasibility = 3.75; language eligibility = 3.79; and presentation feasibility = 3.70); its use has an effect on improving student learning outcomes (with an N-gain score of 0.80); learning achievement obtained with the discovery learning model using the learning media Lectora inspire is higher than the KKM with an average posttest score of 88.21; and students' learning motivation correlated significantly with their learning outcomes.
