The development model used in the study refers to the 4D development model, which consists of the definition stage, the design stage, the development stage, and the dissemination stage. The acid-base e-module based on problem-based learning developed was validated by two experts. After being validated, the acid-base e-module based on problem-based learning was piloted on students at grade  X TKJ 1 at SMKN 5 Jeneponto of academic year 2020/2021 with 27 students. The results show that the acid-base e-module based on problem-based learning developed had conducted a validation process, measuring the level of practicality and effectiveness. The e-module is stated as valid based on the results of the e- module validation with an average value of 3.27 (valid). The e-module is stated as practical based on: (1) the implementation of the acid-base e-module based on problem-based learning at an average value of 1.9 (fully implemented), (2) the teacher's response with an average score of 97.12 (very practical), and (3) the students’ responses with an average score of 81.34 (very practical). E-module is stated as effective based on the results of the N-gain test of 0.76 (high) and classical completeness of 85.19%. Therefore, the results of the study indicate that the acid-base e-module based on problem-based learning has valid, practical, and effective qualities. An outline summary of the acid-base e-module based on problem-based learning through Google Classroom contains a glossary, basic competencies, competency achievement indicators, instructions for using e- modules, concept maps, learning activities 1, 2, and 3, evaluation and answer keys.","PeriodicalId":270408,"journal":{"name":"Chemistry Education Review (CER)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124422549","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}

The type of research used in this study is descriptive research. This research was conducted at SMAN 1 Mamuju to grade XI MIPA students. Data collection techniques employed diagnostic test in the form of multiple-choice stratified. The first level contained the students' answers, the second level was the reason for the answers, and the last level was the level of confidence. Data analysis was conducted by looking for the percentage of misconceptions from each concept in Acid-Base materials, namely the concept of acid-base theory, pH indicators of acid-base solutions, strength of acids and bases, and calculation of pH of acid and base solutions. The results show that the category of students' misconceptions on acid-base materials using the three-tier diagnostic test instrument is the M1 category. In this category, students answered incorrectly at the first and second levels but were sure that the answers at both levels were correct. The percentage obtained in the M1 category is 33.87% with moderate category. Students' misconceptions occur in the concept of acid-base theory according to Bronsted Lowry with a percentage of 70.33% in item 4 and 73.08% in item 18. The concept of pH indicator of acid-base solutions with a percentage of 73.08% in item number 9 while for the concept of the strength of acids and bases with a percentage of 76.36% in item 9. For the concept of calculating the pH of an acid-base solutions, 3 items are obtained that fall into the category of high misconceptions, namely item 14 with a percentage of 83.52%; item 16 with a percentage of 82.42%; and 20 items with a percentage of 78.02%.
