The journal focuses on research papers, literature studies, analysis, and problem-solving in the natural sciences (Physics, Chemistry, and Biology). It also covers the field of natural science education. The journal applies the "publish-as-you-go" procedure to first publish the title of the manuscript that has been reviewed and declared accepted in this journal.</p> <p style="text-align: justify;"><strong><span class="label">DOI: </span><span class="value"><a title="JaMES" href="https://doi.org/10.32665/jansed" target="_blank" rel="noopener">https://doi.org/10.32665/jansed</a></span><br /></strong></p> Universitas Nahdlatul Ulama Sunan Giri Bojonegoro en-US Journal of Natural Sciences and Education <p>Authors who publish with this journal agree to the following terms:</p> <ol> <li>Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a <a href="https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode" target="_blank" rel="noopener">Creative Commons Attribution License</a> that allows others to share the work with an acknowledgment of the work's authorship and initial publication in this journal.</li> <li>Authors can enter into separate, additional contractual arrangements for the non-exclusive distribution of the journal's published version of the work (e.g., post it to an institutional repository or publish it in a book), with an acknowledgment of its initial publication in this journal.</li> <li>Authors are permitted and encouraged to post their work online (e.g., in institutional repositories or on their website) before and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work</li> </ol> https://journal.unugiri.ac.id/index.php/JaNSED/article/view/1422 <p><em>This research aims to develop the physics learning instrumentation equipment with the guided inquiry model and use multi-representation to increase students’ learning, especially in temperature and heat sub-lessons. The advantage of this model is guiding the student through every step of the guided inquiry model. The type of this research is developing research to develop the learning instrumentation by using The Dick and Carey models, with one group pretest-posttest design. This research was conducted in the first level of junior high school of Sumberrejo) at second semester in 2021/2022. The collecting data technique of this research used observation and pretest-posttest. The data analyzing technique was analyzed by using quantitative and qualitative descriptive models. The results of this experiment were the effectiveness of learning equipment included an increase in student outcomes from Tryout II in every class test; the average score was 3.79, categorized as good, based on the student’s activities observation result, which showed that students have been performing activities that should be done during the learning process; also, students’ responses were positive. Based on the results, it can be concluded that physics learning with a guided inquiry model using multi-representation to increase students’ learning outcome on materials temperature and heat was suitable to use so that it can be applied in learning.</em></p> Aprillia Dwi Ardianti Heny Ekawati Haryono Copyright (c) 2023 Journal of Natural Sciences and Education https://creativecommons.org/licenses/by-nc-sa/4.0 2023-02-28 2023-02-28 1 1 1 6
