Abstract

The development of the cognitive conflict-based Student Worksheet (LKPD) plays a role in reducing students' misconceptions regarding hydrocarbons. In this study, the LKPD was created in print format to facilitate the completion of exercises. This LKPD contains information presentations, true statements, and ambiguous statements to create cognitive conflicts for students, as well as reflection questions for conceptual reconstruction. The aim of this research is to determine the validity of the cognitive conflict strategy LKPD. This study employs a Research and Development (R&D) approach based on the 4D development model, which includes Definition, Design, Development, and Dissemination. However, it only reaches the development stage. The research utilized a validation sheet instrument for the LKPD. The validation results indicate that the developed LKPD received a median score ranging from 4 to 5, indicating that the LKPD is valid based on content validity and construct validity. The conclusion of this study states that the developed cognitive conflict strategy LKPD is valid and can serve as an effective learning medium to reduce students' misconceptions about hydrocarbons based on validity aspects.

Abstract

This study aimed to determine the feasibility of student’s worksheet (LKM) for training students' argumentation skills in reaction rate material. The feasibility of LKM was reviewed in terms of validity, practicality, and effectiveness. The type of research used was Research and Development (R&D) with a 4D development model by Thiagarajan with three stages, namely definition, design, and development. A limited trial was conducted in class XI-5 at SMAN 1 Singgahan Tuban. The analysis of the feasibility of the LKM from the validity aspect, as seen from the content and construct, yielded a mode score of 5 in the highly valid category. The practicality aspect of the LKM was seen from the percentage of student response questionnaires of 98.07% and student activity observation sheets of 95.67%, which were classified as highly practical. The effectiveness aspect was analyzed based on the increase in pretest and posttest scores for argumentation skills and learning outcomes, reviewed through a paired sample t-test analysis. Both had a P-Value (1-tailed) of 0.000, so the P-Value (1-tailed) < 0.005, leading to the rejection of H0 and acceptance of H1. Therefore, it can be concluded that LKM is suitable for use as a learning medium to train students' argumentation skills in reaction rate material.
