Abstract

This study aims to describe the feasibility of POGIL-based student worksheets to remediate misconceptions in terms of validity, practicality, and effectiveness, with the object of research of 11th grade students of Al-Islam Krian High School. Validity was measured from the content and construct validation sheets. The responses and activities of students measure practicality. Effectiveness is measured by the percentage of misconceptions that turn toward understanding the concept. The development of this Student Worksheet refers to the development of Research and Development (R&D). The model used is the 4D model, which consists of 4 stages, namely define, design, development, and dissemination. The research that has been carried out is limited to the development stage in the trial step. The validation result data is ordinal data that can be analyzed by determining the mode of each assessment aspect. The validity of worksheet is reviewed from the validity of content and construct which obtained a mode score of 4 with a valid category. The practicality results show that the worksheet is efficient with the activity for each trial of 95.56%, 95.56%; and 97.22%. The practicality of worksheet based on the POGIL learning model in terms of student response questionnaires using a Guttman scale through positive and negative statements with the answers "Yes" or "No" with the results of positive student responses of 95.78%.The effectiveness of the worksheet in terms of the results of shifting misconceptions towards understanding concepts was 81.06% in the theory of acids and bases, 70.09% in the strength of acids and bases, and 69.86% in acid and base indicators, with a significance value of 0.000 in the Wilcoxon test. The results showed that the POGIL-based worksheet developed was feasible to be able to remediate students' misconceptions on acid and base materials.

Abstract

This research aimed to obtain the validity, practicality, and effectiveness of student worksheets oriented on guided inquiry to improve critical thinking skills in acid-base material. The type of research used was 4D model development research, but it was limited to the third stage, namely Develop. The research sample consisted of 34 students from class XI IPA 4 SMAN 14 Surabaya. The instruments used were validation sheets, student response questionnaires, and pretest and posttest question sheets. The validation results show that the student worksheets 1, 2, and 3 in the content criteria get mode 4 in the good category, and construct criteria get mode 5 in the very good category so that overall the teaching module gets mode ≥3 and is declared valid. The overall practicality results of the student worksheets obtained an average percentage of 90.09% with efficient criteria. The results of the overall effectiveness of student worksheets oriented on guided inquiry obtained an n-gain score of 0.71 which is included in the high category. In addition, the sig value. (2-tailed) obtained from the paired sample t-test of 0.000 which shows an increase in students' critical thinking skills and the student worksheets oriented on guided inquiry are effective for use in learning.

Abstract

This research aims to obtain problem-based learning-oriented e-worksheets that are feasible to improve students' critical thinking skills on salt hydrolysis material. This research uses Thiagarajan's 4D method, limited to the development stage. The feasibility of e-worksheets is reviewed from three aspects: validity, practicality, and effectiveness. The limited trial was conducted in class XI-12 State High School 1 Sidoarjo with 37 students. The research data showed that The e-worksheets are declared valid, indicated by the mode of content validity and construct validity of 5 with a very valid category. The e-worksheets are declared practical, indicated by the average results of student response questionnaires of 94% with a very practice category supported by the results of student activity observations. The e-worksheets are declared effective, indicated by the average posttest score higher than the pretest score with N-Gain Score of 0.76 in the high category. The paired sample t-test results showed a significance value of 0.000, indicating a significant difference between pretest and posttest scores. The research findings show that e-worksheets focusing on problem-based learning can be used to improve student's critical thinking skills in learning salt hydrolysis material.

Abstract

This study aims to develop a feasible problem-solving-based E-LKPD on salt hydrolysis material to improve students’ critical thinking skills. The indicators of critical thinking skills include interpretation, analysis, evaluation, and inference. The research employed a Research and Development (R&D) method using the 4D model. The research procedures consisted of the define, design, and were limited to the develop stage. The feasibility of the E-LKPD was reviewed based on validity, practicality, and effectiveness aspects. The validity of the E-LKPD, based on content and construct aspects, obtained a mode score of 5, categorized as valid. The practicality of the E-LKPD was reviewed from the response questionnaire, which obtained an average percentage of 97% categorized as very strong, and the observation results of students’ activities showed an average percentage of relevant activities of 97%, categorized as very strong, while irrelevant activities obtained 3%, categorized as very weak. The effectiveness of the E-LKPD was reviewed from the N-Gain Score results of the pretest and posttest on critical thinking skills, with an average score of 0.81 categorized as high, and the Paired Sample T-Test showed a significance value of ≤ 0.05, indicating that H1 was accepted. These results indicate that the implementation of the problem-solving-based E-LKPD is effective in improving students’ critical thinking skill.
