The research and development of this test instrument used the ADDIE model which consists of 5 stages, namely analyze, design, develop, implement, and evaluate. The study was conducted at SMP Negeri 8 Medan through 2 stages of product trials, namely small group trials with 10 test participants from grades VIII-9, and large group trials with 30 test participants from grades VIII-8. The results of content validity based on the assessment of 5 validators, 25 questions were declared valid and suitable for use. Based on the small group trial, 20 questions (80%) were declared suitable for use and 5 questions (20%) were not suitable for use. In the large group trial, the results of the item validity of 20 questions (100%) were declared valid. The reliability value of the instrument was 0.735 with a high reliability interpretation. Based on the level of difficulty, 20 questions (100%) were obtained with moderate criteria, based on the discrimination power, 6 questions (30%) were obtained with good criteria and 14 questions (70%) with sufficient criteria, based on the effectiveness of distractor options, 20 questions (100%) were obtained with very effective criteria. The teacher's response to the developed test instrument obtained an average value of 89.90% with very good criteria. Based on the results of the data analysis, 20 questions on the developed science literacy test instrument were feasible to use and could measure students' science literacy levels.

THE NEEDS ANALYSIS OF DEVELOPING INTERACTIVE E-MODULE IN SCIENCE LEARNING FOR JUNIOR HIGH SCHOOL

2025-07-30T04:16:51+00:00

The 21st century learning is a learning transition in which the developed curriculum requires schools to be able to change the learning approach from teacher centered to student centered. This is supported by the principle of an Kurikulum Merdeka where to achieve learning outcomes it is necessary to use information and communication technology devices in the learning process. One effort that can be made to support educational goals in the 21st century is the development of interactive e-modules in science learning. The purpose of this study was to determine the need for the development of interactive e-modules in junior high school science learning. The method used in this study is qualitative using a descriptive approach. The instruments used in collecting data were observation sheets, interview questionnaires and student characteristics questionnaires. The results of this study are (1) Science learning in schools is still conducted by teacher centered approach; (2) student have low interest and motivation in learning science; (3) There are less innovative teaching materials used to support the science learning process. The conclusion from this study is the need to develop teaching materials in the form of Interactive E-Modules in science learning so that it is expected that science learning can be conducted by student centered approach and increase student interest and motivation which has an impact on improving learning outcomes.

THE EFFECT OF THE LEARNING START WITH A QUESTION (LSQ) LEARNING MODEL ON THE LEARNING OUTCOMES OF SCIENCE STUDENTS IN HUMAN DIGESTIVE SYSTEM

2025-07-30T05:11:41+00:00

Learning using a scientific approach is ideally accompanied by the activeness of students and students' interest in reading, with active and direct participation of students in learning is able to increase students' understanding of learning material, this will later be in line with the achievement of student learning outcomes, but in reality there are still many students who have scores below the Minimum Completeness Criteria (KKM). The purpose of this study was to find out whether there was an effect of the Learning Start With A Question learning model on digestive system material on the learning outcomes of Class VIII science students at SMP N 29 Padang. This type of research is using quasi-experimental design (Quasi Experimental Design). The research design was the Pretest-Posttest Nonequivalent Control Group Design. The sample selection technique in this study was a purposive sampling technique. The subjects in the study consisted of two sample classes, namely the control class and the experimental class which consisted of 32 people in each class. The results showed that there was an influence of the Learning Starts With a Question (LSQ) Learning Model at SMP N 29 Padang which had an effect on students' science learning outcomes in the cognitive domain, this can be seen from the results of the hypothesis test where tcount > ttable means tcount 2,19 > 1 .67 which indicates that H₀ is rejected and H₁ is accepted, and there is an influence that the Learning Starts With a Question (LSQ) Learning Model at SMP N 29 Padang has an effect on students' natural science learning outcomes in the cognitive domain, as well as affective assessment of the four aspects of class the experimental sample has an average score that is higher compared to the control class so that it can be concluded that the LSQ model affects the academic achievement of students in the affective domain.

The Effect Of Project Based Learning Model Based STEM On The Knowledge Competence Of Class VII Students Of SMPN 8 Payakumbuh

2025-07-30T05:18:14+00:00

The low competence of knowledge can arise due to factors that influence learning, namely the method factors used during the learning process in class, the use of learning models that are less varied, and the enthusiasm of students in learning is still low. One learning model that can be tried to be applied to overcome this problem is the STEM-based Project-based learning model. This research is a type of quasy experiment research that aims to determine the effect of the application of STEM-based project-based learning models on the knowledge competence of class VII students of SMPN 8 Payakumbuh. The research design used was a non equivalent control group design. In the experimental class, STEM-based Project Based Learning was applied, while in the control class, conventional learning was applied. The results of hypothesis testing based on the data obtained in the posttest data research, namely H1 is accepted and H0 is rejected, it can be interpreted that there is a significant average difference in the learning outcomes of students in the experimental class and the control class. So that there is an influence of the project based learning learning model on the knowledge competence of students
