Electronic Student Worksheets based on guided inquiry and assisted by Augmented Reality (AR) and three-dimensional (3D) technology can facilitate the learning process that can be students centered in the era of rapid technological developments and the pandemic covid-19. The purpose of this research was to produce an electronic student worksheets based on guided inquiry assisted by AR and 3D on valid and practical human excretory system topic to be used in science learning at the VIII grade junior high school level. This study used research and development (R&D) methods with a 4D development model consisting of the stages defining, designing, developing, and disseminating, but in this study, there was no disseminate stage. The electronic student Wworksheets was tested on a limited basis to 32 students of class VIII G SMP Negeri 24 Malang. This study E- Student Worksheet Based on Guided Inquiry Assisted By Augmented Reality and Three Dimension on valid and practical human excretory system material used in science learning at the VIII grade junior high school level. The validity of the developed E- Student Worksheet obtained a percentage of 98.02% with a very valid category. The practicality of the E- Student Worksheet in terms of the assessment process, students obtained a percentage of 97% with a very practical category. Meanwhile, the practicality of E- Student Worksheet in terms of student responses obtained a percentage of 93.25% with a very practical category.","PeriodicalId":487442,"journal":{"name":"JCER (Journal of Chemistry Education Research)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138995175","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}

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.","PeriodicalId":487442,"journal":{"name":"JCER (Journal of Chemistry Education Research)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138994813","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}

This type of research was conducted using the Four-D model which was adapted from Thiagarajan which consisted of four stages: define, design, development, and disseminate. However, this research is limited only to the development stage. The LKPD eligibility criteria developed were reviewed from several aspects, namely the feasibility aspect of the content, the presentation feasibility aspect, the language aspect, the graphic aspect, the teacher and student responses. The product has been validated and continued with a limited trial phase was carried out on 16 high school/MA chemistry teachers in the Jabodetabek area and 36 students in class XII science at SMAN 4 Tangerang City. Data were collected using a validation questionnaire which was prepared using the Guttman scale and the teacher and student response sheets were compiled using a Likert scale. The results of the limited trial through the teacher's response questionnaire to the LKPD developed were 86%; and the results of the student questionnaire of 83.5% which are included in the very good category and are suitable for use in learning the colloid concept.","PeriodicalId":487442,"journal":{"name":"JCER (Journal of Chemistry Education Research)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136355798","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}
