Abstract

This research aimed to (1) produce student worksheet based on discovery learning to improve students’ conceptual understanding, (2) analyze the practicality of student worksheet based on students’ responses, and (3) test the effectiveness of student worksheet to improve students’ conceptual understanding. The research used research and development (R and D) method with a 4D model. The trial design used a one-group pretest-posttest. The instruments were the eligibility validation sheet of student worksheets, student response questionnaires, observation sheets, and instrument tests. The data analysis techniques were a five-scale score conversion, implementation of the lesson plan, the percentage of the practicality of the student worksheet, Wilcoxon signed rank test, and n-Gain. The result showed that (1) student worksheet based on discovery learning was feasible to use with the result of the assessment from material and media experts in the very good category, (2) the practicality of the student worksheet was practical with a practicality percentage of 64% in a practical category, and (3) the student worksheet was effective to improve students’ conceptual understanding as seen by the result of the Wilcoxon signed rank test asymp. Sig (2-tailed) 0.001 less than 0.025. So, there were differences in understanding concepts before and after using the student worksheets. The result was strengthened by the n-Gain analysis of 0.4 with a medium category, and there is a significant increase in conceptual understanding.

Abstract

The study aimed to determine the validity, practicality, and effectiveness of electronic student worksheets (e-worksheets) based on problem based learning (PBL) to improve students' metacognitive abilities on stoichiometric material. The research was used a research and development (R and D). The sample of the study was 30 students from SMAN 19 Surabaya. The instruments were validation sheets, student observation sheets, cognitive test sheets, and MAI questionnaires. The metacognition ability was tested using MAI questionnaire on the aspects of planning, monitoring, and evaluating. Then, it was strengthened again with a cognitive test consisting of 6 cognitive questions. The results showed that the developed e-worksheet has 89.76%; 86.67%; 83.33%; and 86.67% of content; graphics; presentation; and language validities, respectively. All components were in the very high category. The results of the practicality of the e-worksheet were 94.64%; 99.29%; 95.24%; 97.62%; and 94.05% for the PBL strategy; metacognitive; graphics; presentation; and language components, respectively. All components were in the very practical category. Based on the t-test, the sig.2-tailed of the planning, monitoring, and evaluating aspects were less than 0.05 so Ha is accepted, which means that the e-worksheet can improve students' metacognitive abilities in those aspects. This is supported by the t-test of students' cognitive abilities where the sig.2-tailed is 0.000 so Ha is accepted, which means that the developed e-worksheet can improve students' cognitive abilities

Abstract

The study aimed to produce a feasible structured assignment sheet as a learning device. The structured assignment sheet was feasible to be used to train the ability to draft a frame of mind in solving chemical problems in reaction rate material. This developed learning device is named SAS-ADFM. The feasibility of SAS-ADFM included criteria of validity, practicality, and effectiveness. SAS-ADFM was developed using the Research and Development (R and D) method. SAS-ADFM was tested on 15 students of class XI who had obtained reaction rate material at SMAN 3 Surabaya. The instruments were the sheets of validation, student response questionnaire, and frame of mind drafting ability test. The validity of SAS-ADFM based on the assessment of three validators met the criteria of validity with a value of Mo ≥ 4 and R ≥ 75%. Meanwhile, the practicality of SAS-ADFM based on the analysis of the assessment of the student response questionnaire produced a very practical category with a percentage of 99%. Finally, the effectiveness of SAS-ADFM based on the analysis of the assessment of the ability to draft a frame of mind produced an N-gain score of 0.5 with a medium category. Hence, the developed SAS-ADFM was feasible to be used as a learning device.

Abstract

The study aimed to describe the critical thinking skills and sustainability consciousness of students of one junior high school in Bandung using an E-module of environmental pollution containing education for sustainability development (ESD). The research used descriptive qualitative and quantitative methods. This study involved 32 participants using a research instrument in the form of critical thinking skills essay questions that contained sustainability consciousness (ESD) with a total of 12 questions. The study indicated that critical thinking skills reach the highest score on the indicator of building basic skills of 78.1% and the lowest score on the concluding indicator of 64.8%. The average score of students' critical thinking skills was 74.4%, which showed the level of students' critical thinking skills in the adequate category. Meanwhile, the sustainability consciousness components showed that the sustainable knowledge, sustainable attitude, and sustainable behavior were constructed with percentages of 82.1%; 79.5%; and 77.8% indicating that the average students’ sustainability consciousness was 79.8% in the good category

Abstract

This study aims to determine the effect of using android-based interactive flipbook media in increasing the mastery of science concepts for junior high school students. The research was conducted in one experimental class and one control class at SMP Negeri 2 Genteng, Banyuwangi. The instruments used were 10 multiple choice questions and 3 essay question with cognitive levels of C1 – C6. The method used is a Quasy Experiment with a pretest posttest control group design. The experimental class and control class were taken by simple random sampling. The data analysis technique used is the analysis of the independent sample T test with the help of SPSS application and the standard gain value using the gain equation. Sig value. (2-tailed) independent sample T test is 0.000, this indicates that there is a significant didfference between the average concept matery of student in the experimental class and control class. Gain value shows that the average mastery of the concepts of experimental class student has increased from before and after treatment of 0.66 with moderate criteria. The average concept mastery of control class students increased from before and after treatment by 0.24 with low criteria.

Abstract

The study aimed to find out students’ science process skill profile in grade XII. The research was conducted at SMAN 1 Tanah Putih Tanjung Melawan, Riau. The study was conducted by providing tests to students consisting of 10 questions on the scope of conventional biotechnology materials. This test used to measure students' science process skills, namely the ability to observe, communicate, interpret, propose hypotheses, apply concepts, ask questions, predict, use tools/materials, plan experiments, and classify. The research sample consisted of 70 students. The reliability value of the instrument was 0.948 of high category. It was obtained that the science process skill of students was categorized as medium with a percentage of 39.3%. The percentage of observing, communicating, interpreting, formulating hypotheses, applying concepts, asking questions, predicting, using tools/materials, planning experiments, and classifying abilities were 43.2%, 35.4%, 39.3%, 28.2%, 26.8%, 36.8%, 46.4%, 49.6%, 37.1%, and 50%, respectively. Some of the science process skill aspects showed a low category, namely in the aspects of formulating hypotheses and applying concepts. Other aspects showed medium category and almost all aspects were below 50%. The teacher’s role was very decisive as the main actor in improving students’ science process skills.
