Abstract

The purpose of this study is to determine the feasibility of the students’ worksheets that is developed to reduce misconceptions with the conceptual change text strategy on the material reaction rate factors. There are three aspects that review the feasibility of students’ worksheets, (1) Validity is to find out the validity of the developed students’ worksheets, (2) Practicality is to find out how practical the students’ worksheets which developed in learning process, (3) Effectiveness is to find out how effective students’ worksheets developed in reducing misconceptions. This research uses the Research and Development (RD) method which has 10 stages (1) Potentials and problems, (2) Data collection, (3) Product design, (4) Design validation, (5) Design revision, (6) Product testing, (7) product revision, (8) usage trial, (9) product revision, and (10) mass production. The subjects in this study are 12 students who detected misconceptions in the material reaction rate factors in class XII MIA 1, and MIA 2 SMA PLUS AR RAHMAT (High School) Bojonegoro. The results of this study indicate that the students’ worksheets developed are feasible to use to reduce misconceptions on the material reaction rate factors as evidenced by the acquisition of the results of the three aspects of feasibility as follow (1) Validity with the percentage of results 89.3% - 93.3% with Very valid category, (2) Practicality with a percentage of 90% - 93.75% with a very practical category, (3) Effectiveness with a percentage of 75% - 90.5% with an effective category.

Abstract

The study aims to describe the applicability of learning model implementation, student activities, learning outcomes, students' analytical skills, and student responses with guided inquiry learning models application. The method used is one group pretest-posttest design with 24 students of XI IPA class. Research shows that (1) quality guided inquiry learning percentage during two meetings is 94.44% and 95.75%, respectively. (2) relevant student activity has an average percentage of 94.64%. (3) student learning outcomes in the factor that affects reaction rate material increases with n-gain scores obtained 83.68% in the high category. (4) the results of student analytical skills on each component with a high category n-gain score are element analysis was 95.83%, relationship analysis was 58.33%, and analysis of organizational principles was 79.17%. (5) the student response had very good category results with a percentage of 98.61%.

Abstract

This research aimed to improve student's learning outcomes on chemical equilibrium material through the application of guided inquiry learning used blended learning to determine students’ activities and student responses for applied learning. This study uses observation and test methods to collect data and One Group Pretest-Posttest Design to determine an increase in student learning outcomes. The research was conducted at SMA Al-Islam Krian for the 2021/2022 academic year. The results showed that implementation of guided inquiry learning based on blended learning was 98.8%, with a very good category. The percentage of student activity is 96%. The learning outcomes obtained by the students showed an increase between the pretest and the posttest, with an average n-gain value of 0.8 in the high category, and from results of paired sample t-test was obtained by the Sig. (2-tailed) 0.000 < 0.005, which means that there is a significant difference. The results of student responses during learning are 96%. This research concludes that guided inquiry learning can improve students’ learning outcomes on chemical equilibrium materials.

Abstract

This study aims to produce the Practical KIT along with its devices that are effectively used as learning media to train students SPS on the sub material of the Reaction Rate Law. The method used in this study is Research and Development design. The research instrument used consisted of a sheet of pre-test and post-test. Data analysis was carried out in descriptive quantitative to determine the effectiveness of Practical KIT along with the devices developed. The media is said to be effective if it meets 2 requirements, namely the percentage of classical completeness <85% and N-gain value <0.3. The developed media has been declared effective as indicated by the increase in the value of cognitive learning outcomes in the "Medium" and "High" categories with 100% classical completeness, an increase in the value of science process skills of students after using the Practical KIT media. "With classical completeness reaching 91.67%.
