Development of Problem-Based-Learning (PBL)-Oriented Electronic Student Worksheets (e-Worksheet) to Improve Critical Thinking Skills of Class XI Senior High School Students on Factors that Influence Rate of Chemical Reactions Material

/in /by

Education system changes from time to time, and with these changes, the existing curriculum in Indonesia also continues to undergo several curriculum updates. The Merdeka Curriculum is the answer to the high level of competition that occurs in the 21st century. Factors that influence the rate of chemical reactions are one of the materials in chemistry phase F of the Merdeka curriculum, which has abstract characteristics and requires experimentation. Based on these characteristics, the problem-based-learning (PBL) learning model is suitable for use and can improve students’ critical thinking skills. This research aims to determine the feasibility of developing a PBL-oriented student e-worksheet to improve critical thinking skills on factors that influence reaction rates. The method used in this research is R&D with a 4D model. The results obtained are that the student e-worksheet developed is feasible because the content and construct validity results obtained in mode 5 with a very valid category, then the practicality results obtained a response questionnaire score of 98.44%, which was supported by the results of the student activity sheets, and the effectiveness was obtained. From the data from the pretest and posttest results, which were analyzed using the SPSS Paired Sample t-Test, the results showed that there was an increase in students’ critical thinking skills, namely with a significance value of 0.00.

The Importance of E-Worksheet Based on Problem Based Learning Activity to Improving Student’s System Thinking Skills: Science Teacher’s Perspective

This research aims to describe the importance of learning media in the form e-worksheet with a problem-based learning model to improve students’ systems thinking skills which focuses on Energy material. The research model used is the 4D development model (Define, Design, Develop, Disseminate). This article reports on the Define stage. Data collection was taken from literature studies and distributing questionnaires via Google Form, then descriptive analysis was carried out. The teacher respondents in this research were 25 science teachers in Lampung Province. The results of the research show that 60% of the problems experienced by teachers in the field are the lack of teaching materials and learning media that are able to stimulate 21st century skills. As many as 78.3% of teachers have not trained systems thinking skills which are part of 21st century skills. Literacy study results shows the importance of learning media with problem-based learning to improve systems thinking skills.

The Implementation of PBL-STEAM Equipped with JBatik Software as Learning Media to Enhance Students’ Creative Thinking Skills in Designing Batik Motifs of Indonesian Local Heritage

The aim of this research is to analyze the student’s creative thinking skills under the implementation of the Problem-Based Learning Model equipped with JBatik software. This study used a quantitative approach with a quasi-experimental design: pretest-posttest non-equivalent group design. The research respondents consisted of two classes: the control class with 31 students and the experimental class with 29 students. The research instruments used were interviews, questionnaires, observations, and creative thinking tests. Data analysis techniques used a one-way ANOVA test, LSD post hoc test, and independent sample t-test. The one-way ANOVA test results showed a sig value of 0.000 < 0.05, indicating a significant influence of applying the Problem-Based Learning Model Integrated with Information Technology on independence. The LSD post hoc test showed a mean difference between the experimental group of 9.600 and the control group of 5.067. The results showed that based on the independent sample t-test analysis on the post-test, there was a significant difference between the control class and the experimental class. It is due to the sig (2-tailed) score is 0.002 (p = <0.05). The qualitative analysis shows all the Pearson Correlation Coefficient values are less than 0.7. Based on this, there is no significant similarity between the interviews Thus, it can be concluded that the experimental group taught using the Problem-Based Learning Model Integrated with Information Technology has a better effect on independence compared to the control group taught using the Problem-Based Learning Model-STEM.

Development of E-Module Based on Problem Based Learning by Using Adobe Flash Professional CS6 on the Material of Human Respiratory and Excretory Systems for Students of Class VIII SMPN 25 Padang

Good results from education must be accompanied by effective learning. Effective learning one of which is influenced by the use of teaching materials. Preliminary investigation data at SMPN 25 Padang show that there is no teaching material in the form of an e-module that can visualize the subject matter as a whole. Based on the results of the questionnaire, it is known that 67.16% of students have difficulty understanding the concepts of the respiratory system and the excretory system. This causes the low learning outcomes for students, so teaching materials are needed that can assist in visualizing the subject matter as a whole. This study aims to produce an e-module based on problem based learning using adobe flash professional CS6 on the material of the human respiratory and excretory systems for students of class VIII that is valid, practical, and effective. This type of research is the Plomp model development research which consists of three phase, namely the initial preliminary research phase, the development or prototyping phase, and the assessment phase. The research subjects are students of class VIII SMPN 25 Padang Academic Year 2021-2022. The research data were obtained from validity, practicality, and effectiveness tests. The validity test data was obtained through a validation sheet by lecturers as validators. Practical test data was obtained from the results of the questionnaire response analysis of teachers and students. Effectiveness test data were obtained from multiple choice question sheets for assessing cognitive competence, observation sheets for assessing affective competence and psychomotor competence, and essay question sheets for assessing students creative thinking skills. The results of validation by validators on the e-module based on problem-based learning show an average value of 86.35% (very valid). The results of the practicality assessment by science teachers showed an average of 90.87% (very practical) and the results of the practicality assessment by students obtained an average value of 89.25% (very practical). The results of the effectiveness test from the cognitive, affective, and psychomotor aspects of students showed that the problem based learning based e-module was very effective and the value of creative thinking skills obtained an average of 74.24 (creative). Thus, it can be concluded that the problem based learning based e-module developed is very valid, very practical, very effective, and can train creative thinking skills.
