This research is an ADDIE-based development research with analysis, design, development, implementation, and evaluation stages. Limited trials were conducted on students in basic chemistry classes. The validation results show that e-workbook is valid, practical, and effective. The results of limited trial showed that collaboration skills improved in the good category with average score is 75%, and critical thinking skills improved in the medium category with average score is 0.33. It shows that the interactive e-workbook based on the PLTL model can improve collaboration and critical thinking skills and can be used to solve problems in group discussions with the help of an expert leader.","PeriodicalId":33527,"journal":{"name":"JTK Jurnal Tadris Kimiya","volume":"641 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77528626","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}

Based on experts’ suggestion, intertextual-based learning activities involving three levels of chemical representation with POE learning steps to build the concept of the effect of the nature of the reactant and catalyst on reaction rates and develop students' science process skills. The strategy consists of five phenomena which are followed by three experiments and two videos as observation tools for the student. The explanation stages are guided by sets of guiding questions that involve multi-representation levels in that explanation.

The use of technology has become an efficient alternative in the implementation of learning. This research aims to implement the protein metabolism electronic modules (e-modules) as biochemistry teaching materials to improve students’ critical thinking (CT) skills. This research refers to comparative quantitative nonparametric methods by comparing measurements of CT skills before applying e-modules during the lesson with the height of CT skills after using the e-module. The e-modules include videos, images, animations, links to various primary sources, and formative tests that follow the learning outcomes. As the result, the advancement of CT skills from the final measurements illustrated a reduction in the number of students categorized as bad and poor and an increasing number of students categorized as good and excellent. Furthermore, the skill improvement can also be seen through the Two Tail T-Test, with a tcount of 4.7752, while the ttable value for the Two Tail T-Test of 2.0262. Since tcount > ttable suggests a significant difference between the initial and final measurement scores test, H0 is rejected, and H1 is accepted.

The data shows that only 10% of Indonesian children like to read a book, while most chemistry material is written in textbooks. This study aims to produce digital comics with chemical bonding material, determine comics' feasibility, and respond to readers. The research method develops the Borg and Gall model with seven stages of development without compromising the essence of the model. Meanwhile, data collection techniques are interviews, validation, and questionnaires using a Likert scale. The media and material validator has validated the product developed in this study. As a result, the media aspect has an overall score of 48 or 100%; the score belongs to the very decent criteria. The material aspect has got a score of 26 or 93% from the basic chemistry lecturers; Also, the chemistry teachers give 100%. In addition, the digital comic readers have an extensive test. Conversely, 48 respondents have been assessed with an overall score of 2753 or 90%. Hence, this percentage value relates to the very feasible category.

The experimental class sample was given treatment of the CTL learning model while the control class used conventional learning, respectively, were 31 and 30 students of 93 populations. Based on a questionnaire, students' creative thinking skills were obtained through observation during the learning process. The data analysis of the test instrument was carried out through a validity test using the product-moment correlation technique (significant level = 0.05), Lilliefors normality test, homogeneity of variance test and ttest. The CTL implementation questionnaire and instrument test data were converted into percentages and categorized. The results showed that the application of the CTL model had a positive effect on students' creative thinking abilities, evidenced by the average score of students in the experimental class before and after treatment increased from 14.55 to 74.84. Otherwise, in the control class, the scores were 30.59 to 33.56. The percentage of students' achievement in creative thinking aspects in the experimental class was good (61%-80%) while the control class was less good (21%-40%). The creative thinking abilities of both classes are very different, which is also reflected in the learning outcomes. The value of tcount (2.240) was greater than ttable (2.042) at the significant level = 0.05, and the hypothesis of H0 was rejected, or H1 was accepted.
