Abstract

This study aimed to investigate the impact of the Argument-Driven Inquiry instruction (ADI-Based Instruction) in thermochemistry on students' critical thinking skills. This study applied the one group pretest-posttest type of pre-experiment design. The subjects of this study were 71 eleven grade students of Public Senior High School of Ambulu Jember on academic year of 2022/2023. The instrument, namely the critical thinking ability test on thermochemistry, was developed by the researchers based on Ennis' critical thinking ability framework. This test consists of 10 valid items with a Cronbach's Alpha reliability of 0.782. The results showed that thermochemistry instruction carried out using ADI instructional model improve students' critical thinking skills with an N-gain of 0.731 (high category) and Cohen's d-effect size of 1.023 (large effect category) with an intermediate reliability of 0.619 (good categories). These results indicate that ADI-based instruction on thermochemistry can improve students' critical thinking skills. The implication of this study is that ADI-based instruction can be applied to other subjects who have the same characteristics of thermochemistry, namely having contextual, factual, conceptual, procedural, and metacognitive knowledge.

Abstract

Chemistry is a science that studies the composition, structure, and properties or changes of matter. In chemistry, there are three levels of representation namely macroscopic, submicroscopic, and symbolic. Chemistry is a branch of science that requires students to have an understanding of concepts and mathematical skills, one of which is colligative properties. The aim of this research is to analyze the concept of colligative properties so that students don’t have misconceptions and can enhance their understanding through a multi-representation approach. The method used is the scientific approach, based on a series of five main learning experiences: Observing, Questioning, Reasoning, Associating and Communicating. Information collection techniques include concept maps, concept analysis, and propositions. Colligative properties consist of vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure. The van't Hoff factor is present in most colligative properties where the solute is an electrolyte substance.

Abstract

Chemistry learning at SMA Negeri 1 Kalasan still uses conventional teaching materials. Teachers have never developed and used interactive LKPD. Molecular shape is one of the topics that is considered difficult, abstract, and challenging, so teaching materials are needed that can visualize the concept well, one of them through using Augmented Reality technology. This research aims to: (1) create product that fulfill the development feasibility criteria; and (2) find put the response of students to the product during trial. This study is Research and Development (R&D) that refers to the 3D development model, namely Define, Design, and Develop. The instruments used in this study were interview sheet, survey questionnaire, validation sheets, questions item in the product, and questionnaire for students' response to the product. A number of 10 students of X MIPA class were selected through purposive sampling technique as research sample. The research data obtained were analyzed descriptively. The results showed that: (1) product has fulfilled the criteria of being very feasible and very valid with average percentage of 87%, very effective with average score of 99 that also supported by the acquisition of average percentage of completeness of working on questions of 97%, very practical with average percentage of 93%; and (2) students' response to the product is very good. The average percentage of student’s responses per aspect item in the questionnaire was 92.81%. About 70% students stated that product is interesting and easy to understand.

Abstract

This research aims to create POGIL-based E-Worksheet learning media on Covalent Bond material to increase students' learning independence. This research uses R&D (Research and Development) research to produce and test the effectiveness of media by adapting the model developed by Plomp (2010). The subjects of this research were class XI students of SMAN 1 Menganti. The validity results based on assessments from experts were found to be 85.7% for content validity which was included in the very valid criteria and 90.7% for construct validity which was included in the very valid criteria. This E- Worksheet is also considered practical in terms of the student response questionnaire with a score of 77.3% or in the very practical category and the results of observations of student activities obtained a score of 88.9% or in the very practical category. Furthermore, the effectiveness results based on the learning independence questionnaire obtained an n-gain score of 0.71 or in the high category. Based on these results, this E- Worksheet can be used as a learning medium to increase students' learning independence.

Abstract

The periodic system of elements is one of the complex chemical materials. The results of previous research show that the learning achievement of boarding high school students has an understanding that is only limited to the macroscopic level. Visualization of chemical representation level requires high visual intelligence. Therefore, researchers developed a module of periodic system of elements as an independent learning media for high school boarding school students in improving visual intelligence. This study aims to analyze the validity, practicality, and effectiveness of the module. The type of research used is the ADDIE method with five stages, namely Analyze (analysis), Design (design), Develop (development), Implement (implementation), and Evaluate (evaluation). The module in terms of content and construction showed a very valid category. The results of observations of module implementation show a very practical category. The module is very effective to improve students' visual intelligence with an n-gain value of 0.753434. The results showed that the periodic system of elements module is feasible to use as a solution to improve students' visual intelligence.
