This type of research uses pre-experimental research with a one group pretest posttest design. The subjects of this study consisted of 30 students of class VIII-H at SMP Negeri 30 Surabaya in the academic year 2022/2023. The research instruments used were pretest-posttest test sheets and student response questionnaires. The data collection techniques used were tests and questionnaires, with data analysis techniques including data analysis techniques for improving learning outcomes using normalized gain (N-gain) and analyzing student response questionnaire data. The results of this study include, (1) the learning outcomes of students experienced a significant increase as evidenced by the average value of normalized gain (N-gain) obtained a high category, (2) the results of students' responses obtained an average percentage of 98.5% with a very good category. Based on the results of the research conducted, it can be concluded that the application of teaching materials assisted by Smart Apps Creator (SAC) can improve student learning outcomes on vibration and wave material.</p> Eva Lestari Siti Nurul Hidayati ##submission.copyrightStatement## 2023-07-31 2023-07-31 11 2 138 142 ANALISIS KEAKTIFAN BELAJAR SISWA DALAM MODEL PEMBELAJARAN KOOPERATIF TIPE TGT PADA MATERI KINEMATIKA GERAK LURUS <p>This study aims to analyse student learning activeness in the TGT type cooperative learning model on straight motion kinematics material. The research method used is quantitative descriptive research. This research was conducted at a junior high school in Surabaya in the 2022/2023 2<sup>nd</sup> semester academic year, with the class VIII-I class consisting of 25 students. The data collection technique in this study is the observation method. Learning using the TGT type cooperative learning model was carried out very well. Based on indicators of student learning activity, in the first meeting the average student activity was 52%, with good activeness criteria, in the second meeting, the average student activity was 79%, with very good activeness criteria. So, it can be concluded that the use of the TGT type of cooperative learning model in classroom learning can increase student learning activity.</p> Mochammad Danu Devasyah Erman Erman ##submission.copyrightStatement## 2023-07-31 2023-07-31 11 2 116 121 PENERAPAN TIPE PEMBELAJARAN TEAM GAMES TOURNAMENT DENGAN MEMANFAATKAN MEDIA QUIZIZZ UNTUK MENUMBUHKAN MOTIVASI BELAJAR SISWA <p>This study aims to determine the motivation level of students when TGT type cooperative learning is applied by using Quizizz digital games media. This study used a one group posttest only design.&nbsp; The data collection technique consists of a questionnaire method and an observation method to measure the level of student motivation and is supported by the interview method.&nbsp; The results of this study indicate that from the results of questionnaires and observations obtained a very high level of student learning motivation. However, the interview results show that this learning is more suitable if used as innovative learning in learning assessment. The conclusion of this research is that the TGT type of learning has an effect in fostering student learning motivation and it is recommended that supporting learning is needed before the tournament to support students to gain knowledge about the material to be tournamentized.</p> Chika Vindi Pramita Elok Sudibyo ##submission.copyrightStatement## 2023-07-31 2023-07-31 11 2 122 126 STRATEGI PENANAMAN SIKAP PEDULI LINGKUNGAN MELALUI PEMBELAJARAN IPA UNTUK SISWA SMP <p>The purpose of this research is to describe a strategy for instilling an attitude of caring for the environment through learning natural sciences for junior high school students. The type of research used was descriptive, with the targets being the principal, 1 science teacher, and 6 students. Data collection techniques included learning observation, document analysis, and interviews. The results showed that the habituation method, implemented through science learning, facilitated the instillation of an attitude of caring for the environment. The strategies employed by the teacher included: 1) accustoming students to cleaning the classroom before starting learning, 2) encouraging students to solve problems related to the environment in connection with the learning material, 3) familiarizing students with explanations regarding environmental management, and 4) fostering students' engagement in creating works related to the environment. These findings were supported by interview data, which indicated that science teachers applied a strategy of instilling an attitude of caring for the environment by encouraging students to act and think critically about environmental management.</p> Lucy Virarasari Erman Erman ##submission.copyrightStatement## 2023-07-31 2023-07-31 11 2 132 137 VALIDITAS INSTRUMEN PENILAIAN KEMAMPUAN BERPIKIR KRITIS PADA MATERI SISTEM PERNAPASAN <p>The purpose of this research is to make an evaluation tool for critical thinking skills related to the subject matter of the respiratory system. This study used a research and development approach using the Planning, Production, and Evaluation (PPE) framework. The research process consists of three fundamental stages, namely the planning stage, the production stage, and the evaluation stage. The assessment instrument has gone through a validation process involving three validators. Assessment of the validity of the material consists of five aspects that must be examined, one of which is related to the suitability of the questions with indicators of critical thinking. The material validity assessment shows a validity value of 100% which indicates the ability of the instrument to measure the material in question accurately. The assessment of the construction aspect consists of eight aspects that must be reviewed resulting in a validity value exceeding 75% for each item indicating that the developed instrument meets the validity criteria. The assessment of the language aspect which consists of five aspects that must be studied produces a validity value that exceeds 75% for each item so that it shows the validity of this instrument. This shows that the evaluation tool in the form of an assessment instrument for critical thinking skills that has been developed can be declared valid for evaluating critical thinking skills in the material on the respiratory system.</p> Ananda Ayu Kurniawati Wahyu Budi Sabtiawan ##submission.copyrightStatement## 2023-07-31 2023-07-31 11 2 127 131 MIND MAPPING : PERLUKAH DITERAPKAN UNTUK MENCAPAI PEMAHAMAN KONSEP? <p>Pre-research activities show low student’s learning outcomes on human respiratory system material. This is due to not achieving concept understanding according to predetermined learning indicators. The solution formulated is to train cognitive learning strategy in the form of mind mapping to help the learning process. The mind mapping strategy can facilitate the achievement of concept understanding indicators at the Bloom’s Taxonomy cognitive level, so it was chosen as a solution to overcome the problem. The purpose of this study was to determine the effectiveness of mind mapping strategy in improving students’ concept understanding. The type of research used is pre-experimental with a one-group pre-test and&nbsp;&nbsp;&nbsp;&nbsp; post-test design. The research subjects involved 32 students from VIII–F class at a SMP in Sidoarjo. The results showed that the mind mapping strategy was effectively used to improve students’ concept understanding as shown by the acquisition of the t<sub>statistics</sub> &gt; t<sub>table</sub> value, namely 12.440 &gt; 2.036 and the n-gain value of 0.70 with high criteria. Based on these results, it can be concluded that the implementation of mind mapping learning strategy can improve students’ concept understanding.</p> Amanda Salsabila Ilhami Dyah Astriani ##submission.copyrightStatement## 2023-07-31 2023-07-31 11 2 143 149 PENERAPAN MODEL INKUIRI TERBIMBING UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KRITIS PESERTA DIDIK <p>This research aims to compare the critical thinking skills of students on the application of guided inquiry learning model.
