Science process and critical thinking skills must be possessed by students as prospective professional teachers. Quality practicum activities with quality teaching materials can improve science process skills and low critical thinking. The practicum guide only asks students to carry out practical activities according to existing procedures, so students cannot build their skills. This study aims to develop an inquiry-based practicum guide that meets the valid, practical, and effective criteria for science process skills and critical thinking. This research is development research based on the Hannafin & Peck model with three stages, namely needs assessment, design, development, and implementation, piloted on a small scale, namely 20 students in basic chemistry courses. The results showed (1) Valid with a value of 3.5. Practical with a score of 3.81 on lecturer activities and 3.3 on student activities. Effective with 90.5% getting a positive response. (2) Science process skills are very good, with a score of 88.54%, and critical thinking skills with the results of hypothesis testing Sig (0.001) > 0.05, while the gain score test is 0.45 in the medium category. This guided inquiry-based practicum guide can be used because students design, formulate hypotheses, and conclude independently to improve their science process and critical thinking skills.

The use of teaching materials that support higher-order thinking skills (HOTS) on thermochemical materials still needs to be improved, which makes students' critical thinking skills (CBC) low. The goal of this study is to find out if HOTS-based chemistry learning modules on thermochemical materials and improving CBC are possible and what students think of them when they are used. This study is a type of development research called "ADDIE" research. Three experts on materials, three experts on the media, and three teachers took part in this study. As the control group, 35 people were used, and as the experimental group, 36 people were used. In this study, both non-test and test methods were used to collect data. The non-test method was done with the help of a product validity questionnaire sheet, which was a research tool. On the other hand, the instrument test looked at how well students could think critically. Descriptive qualitative analysis, quantitative statistics, and inferential statistics are used to look at the data (t-test). The average CBC of students was different before and after they used HOTS-based chemistry modules to study thermochemistry materials. The results show that using HOTS-based chemistry modules to improve students' CBC is better than using standard modules. It was decided that chemistry modules based on HOTS could help students learn how to think more critically.

Chemistry is a very important branch of science because it deals with phenomena that often occur in everyday life. In chemistry learning, students are invited to study the material and its changes. Chemistry learning is considered very abstract because it cannot be seen directly by the naked eye. It causes most high school students to think that chemistry is difficult—limitations of learning during the Covid-19 pandemic affected various abilities possessed by students. Students lack critical thinking skills, namely, the inability to analyze and provide solutions to simple problems. The purpose of this research is to develop students' critical thinking skills through the application of the STEM-PBL approach to online learning. This research uses a qualitative descriptive method with observation sheet instruments and test questions. STEM integrated into PBL is one of the solutions to improve students' critical thinking skills. The results of the application of STEM-PBL show an increase in students' critical thinking skills in solving everyday problems. Students can also design tools to solve problems and integrate various disciplines.

{"title":"Practical Guide for Determining the Reaction Rate and Reaction Order Based on the Colorimeter® Application","authors":"Azwa Fadilla Wafiq, Husna Amalya Melati, Erlina, Hairida, Masriani, Risya Sasri","doi":"10.23887/jpki.v6i2.50365","DOIUrl":"https://doi.org/10.23887/jpki.v6i2.50365","url":null,"abstract":"The practical activities needed in chemistry lessons. However, during the covid-19 pandemic, a suitable practical guide is needed. Therefore, a practical guide that can involve students directly in practical activities in online learning and blended learning is needed. The purpose of this study is to determine the feasibility of the Practical Guide for Determining Reaction Rate and Reaction Order Based on the Colorimeter® Application based on expert judgement and students’ response. This study employs a research and development (R&D) using 4D(Four-D) model, starting from define, design, develop, and dissemination stages. This research is limited to the develop stage due to the limited time and ability of the researcher. The subject of this study was a practical guide which was tested to 6 students in the initial trial and 20 students of Chemistry Education FKIP Untan in the main trial. Data collection tools used are the feasibility assessment sheets and students’ response questionnaires. The results of expert assessment using the Gregory test closeness model indicate a very feasible criteria with the validity value of 1.00 which in a very high level in terms of the feasibility of the content, language, and graphics. The result of the initial trial and main trial obtained an average percentage of 91% and 94% respectively with very good criteria. The results of this study imply that the practical guide developed is suitable for use in the practical activities. In addition, the practical guide has an attractive appearance and can be used in practical activities to support students’ understanding of reaction rates’ concepts.","PeriodicalId":296575,"journal":{"name":"Jurnal Pendidikan Kimia Indonesia","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130792600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
