This research is development research that uses the ADDIE development model. Data collection techniques in this study include interviews, validation sheets, observation sheets on the implementation of learning, tests, and student response questionnaires. The data obtained was then analyzed to determine the validity, practicality, and effectiveness of the e-module product. The results of the research are valid, practical, and effective product development so that the product in question is feasible to use. The results of product validation show that e-modules are included in the very valid category with a validation value of 92.5%, which means their assessment is seen from two aspects, namely content validity and construct validity. This product is included in the very practical category based on its practicality value of 93.56%. This product is also included in the effective criteria, which is seen based on the test results with an n-gain value of 0.60 and the results of the student response questionnaire of 88.97%, which is included in the very good criteria. Thus, the developed e-module product can be said to be feasible to improve the scientific explanation skills of junior high school students in science learning.</p> Muhammad Rojikin Ridlo Zainur Rasyid Supeno Supeno Copyright (c) 2022 Muhammad Rojikin, Ridlo Zainur Rasyid, Supeno Supeno https://creativecommons.org/licenses/by/4.0 2022-05-31 2022-05-31 6 1 1 21 10.21070/sej.v6i1.1618 Application of the Science Literacy Circles Method Based on Local Reality to Improve Students' Scientific Literacy https://sej.umsida.ac.id/index.php/sej/article/view/1619 <p class="root-block-node" data-paragraphid="20" data-from-init="true" data-changed="false">This study aims to determine the effectiveness of the Science Literacy Circles (SLC) method on students' scientific literacy skills. <span class="red-underline" data-startindex="133" data-endindex="163" data-paragraphid="20">Research subjects are students </span>of Biology education, FKIP UNSRI, who take an Introduction to Environmental Science course, Environmental Pollution material. This study uses a post-test-only control design. The students who were the samples in this study were taken using a purposive random sampling technique with the Indralaya class as the control class and the Palembang class as the experimental class, each with 1 class. The data analysis technique was carried out using an instrument sheet in the form of a test sheet. Based on the results of the study, it was shown that the experimental class had a higher achievement of scientific literacy skills than the control class in terms of several aspects of scientific literacy, namely aspects of competence, context, and attitudes towards science. The average percentage for the three aspects measured was obtained at an average of 69.03 for the control class and 82.88 for the experimental class.</p> Nike Anggraini Khoiron Nazip Copyright (c) 2022 Nike Anggraini, Khoiron Nazip https://creativecommons.org/licenses/by/4.0 2022-05-31 2022-05-31 6 1 23 33 10.21070/sej.v6i1.1619 The Effect Of Discovery Models With Blended Learning Strategies Assisted By Crossword Puzzle Media On Understanding Physics Concepts https://sej.umsida.ac.id/index.php/sej/article/view/1620 <p>This study aims to see the effect of the application of discovery learning models with blended learning strategies assisted by Crossword Puzzle media on the ability to understand students' physics concepts by choosing. This study used a pre-experimental method with a one-shot case study design consisting of 1 experimental class as a sample class which was carried out at SMP Negeri 1 Botupingge. The data obtained were in the form of understanding students' physics concepts on the material of vibration, waves, and sound which were netted using a multiple-choice test sheet as many as 20 items. The overall research results show that the application of discovery learning models with blended learning strategies assisted by Crossword Puzzle media has a significant effect on students' ability to understand physics concepts which is shown by proving the hypothesis test that the value of t table&gt; t count which states that the lowest student learning outcomes are 75, where from the total sample of 69 respondents, 82.61% or 57 respondents scored above 75.</p> Ois Bokingo Supartin Supartin Abdul Haris Odja Copyright (c) 2022 Ois Bokingo, Supartin Supartin, Abdul Haris Odja https://creativecommons.org/licenses/by/4.0 2022-05-31 2022-05-31 6 1 35 47 10.21070/sej.v6i1.1620 The Analysis of Pedagogical Content Knowledge (PCK) at Natural Science Teachers in SMP Negeri 4 Sidoarjo https://sej.umsida.ac.id/index.php/sej/article/view/1622 <p><em>This study aims to analyze (1) Pedagogical Content Knowledge (PCK) profile of IPA teachers in teaching science in terms of PCK component in pentagon model (2) constraint of PCK science teacher in teaching science. The PCK component consists of five components including: Component K1 (teaching orientation), K2 (knowledge of Curriculum), K3 (knowledge of students), K4 (knowledge of learning strategy) and K5 (knowledge of assessment). The research is a qualitative with phenomenology approach. The subject of the research was a science teacher at SMPN 4 Sidoarjo. Data collection techniques in this study using documentation, observation and interviews. Data analysis phase using Miles and Huberman model. Test the validity of the data used triangulation technique. Based on the research results revealed PCK teacher profile: K1 component is science learning oriented to develop the cognitive, psychomotor and affective aspects of students by applying constructivism learning theory, K2 component that is understanding the curriculum 2013 and apply it to learning but conducted development on objectives, content and learning materials, K3 component: identify that students do not experience misconception and in managing the classroom asking the students who have the advantage to help other students, K4 component is applying discovery learning model with scientific approach 5M (observing, asking, collecting data, associating and creating), K5 component</em> <em>is the assessment of the students covering 3 aspects (cognitive, affective and psychomotor) with assessment methods of quetion and observation, and teachers do not experience PCK constraints in teaching Water Pollution Material. In the next research is expected to reveal three other teacher competencies.</em></p> <p>&nbsp;</p> Mochamad Nashrullah Septi Budi Sartika Nur Efendi Copyright (c) 2022 Mochamad Nashrullah https://creativecommons.org/licenses/by/4.0 2022-05-31 2022-05-31 6 1 49 58 10.21070/sej.v6i1.1622 The Impact of Online Education System at Student's and Teacher's During Covid-19 Pandemic in Pakistan https://sej.umsida.ac.id/index.php/sej/article/view/1541 <p>This study aims to describe the impact of the online education system on students and teachers during the covid-19 pandemic in Pakistan. The research method uses qualitative research, namely literature studies by examining the results of previous research related to the implementation of the existing education system in Pakistan. There are several research results to be studied, which provide a description of policies in the implementation of education during the covid-19 pandemic in Pakistan. Data analysis techniques use descriptive qualitative analysis, with reference to Miles &amp; Hubberman's analysis, namely data reduction, data display, and conclusion drawing. The results showed that the online education system during the covid-19 pandemic in Pakistan, includes 1) learning that was temporarily interrupted due to the lack of technology actually provides challenges in solving problems faced by both teachers and students, 2) the readiness of online learning is expected to run effectively if there are clear guidelines / procedures,&nbsp; learning planning, self-efficacy and internal motivation, access services, especially online libraries, online communication, and significant online connectivity, 3) the Covid-19 pandemic is used as a challenge in the world of education to continue to provide maximum service in the midst of a crisis because education is closely related to the quality of human resources, and 4) Teachers can develop pedagogical innovations to fit the requirements of online learning where bringing conventional classes online. this study will help policymakers and the Ministry of Education in Pakistan to focus more on human resource development, interpersonal development, communication and technology management training, and support programs, especially for school teachers as the foundation of the next and future generations.</p> Hassan Karim Manahil Hafeez Copyright (c) 2022 Hassan Karim, Manahil Hafeez https://creativecommons.org/licenses/by/4.0 2022-05-31 2022-05-31 6 1 59 63 10.21070/sej.v6i1.1541
