This study aimed to explain the effectiveness of Introduction to Nuclear Physics E-Module as a teaching material during Covid-19 Pandemic descriptively. The e-module was made by using Flip PDF Professional application. This study aimed to: (1) describe students’ learning outcomes before and after the implementation of e-module, (2) analyze the effectiveness of e-module descriptively through normalized Gain <g>; (3) describe the practicality of the e-module according to students as the users. The research instruments consisted of students’ test results and practicality questionnaire in the use of nuclear physics e-module. The results obtained showed that: (1) There was a difference of the pretest-posttest mean score descriptively; (2) The e-module was effective descriptively to boost students’ learning outcomes through normalized Gain analysis <g>; (3) The practicality of the e-module was in the ‘very practical’ category based on students as the users. Therefore, The nuclear physics e-module can be applied as the effort to provide teaching material in physics lecture during Covid-19 pandemic.

This study aims to produce interactive physics learning media based on macromedia flash 8 straight motion material for Class VII Students of SMP / MTs. This type of research uses the Research and Depelopment (R&D) approach by adopting the ADDIE (Analyze, Design, Depelopment, Implementation, and Evaluation) development model. Design a learning media trial using the Post-Test Only Control Group Design. Data collection instruments in the form of material expert evaluation questionnaire, media expert evaluation questionnaire, natural science teacher evaluation questionnaire, student response questionnaire, multiple choice tests and student learning activity questionnaire, data collection techniques namely test techniques and observation techniques. Data analysis techniques are media feasibility test, normality test, variance homogeneity test and hypothesis test. The results of the study of the feasibility aspects of instructional media, media experts declared worthy of an actual score of 75, material experts declared worthy of an actual score of 73, the subjects of Natural Sciences stated worthy of an actual score of 66, and the average score of actual responses of 4 students was 58.25 . While the results of research on the aspect of learning media testing shows that interactive physics learning media based on macromedia flash 8 is effective on student learning outcomes with an average experimental class score of 70.38 and classical learning completeness of 71.42%. The percentage of active students in the good category with a percentage of 69.09%. When compared with the control class with an average value of 50.37 and classical learning completeness 22.22%. The percentage of active students in the category is sufficient with a percentage of 41.82%..

This study aimed at detemining the effect of Problem Based Learning Model on the ability of students’ critical thinking through lesson on the topic of effort and energy. The method of research was an experimental research by using post-test-one control group design. Experimental class was treated by problem based learning, while the control class was taught by conventional learning through lesson study. Population of this research was the high school at Al Hamzar, Tembeng Putik of the X grade which consisted of two classes. Those were X Mathematics and natural science 1 and X Mathematics and Natural Science 2 with the total number or students was 58. The sampling thechnique applied was saturated sampling technique. Then, the instrument used in the present research was essay test which contained 6 items. The test arrangement followed the indicators of critical thinking with a variety of possible answers. Having implemented both in the experimental and in the control class, there were improvements in learning process in tems of managing the time, the students and doing aperception. Testing hyphoteshis result by uisng t-test showed t-test = 1. 25 and t-table in signifance level was 5% was 0. 07, so t-test> t-table which meant the alternative hyphothesis (Ha) was accepted and null hyphothesis (Ho) was rejected , it could be concluded that problem based learning thorugh lesson study was significantly effective in students’ critical ability on the topic of effort and energy for the tenth garade students at Al Hamzar high school.

This study aims to determine 1) Effect of the Problem Based Learning (PBL) based local wisdom model towards students’ learning achievement 2) Effect of the critical thinking towards students learning achievement 3) Interaction between the use of learning models and critical thinking skills towards student learning achievement. This study was experimental study. The population of this study were all students of class X IPA at SMA AL-Hamzar Tembeng Putik in academic year 2019/2020. The sample of this study was selected by saturated sampling technique which was Class X IPA 1 as an experimental class while class X IPA 2 was as a control class. The research design of this study was 2 x 2 factorial design. the data collection techniques of this study used critical thinking questionnaires and achievement tests. The data were analyzed by using two ways Anova. The results showed that; 1) there was an effect of problem based learning (PBL) based local wisdom on student learning achievement, it proved by the result of FA count> Ftable was 11.29> 4.00, which meant H0A was rejected, 2) There was an effect of critical thinking skill towards student learning achievement, it proved by the result of FB> Ftable was 5.51> 4.00 which meant that H0B is rejected. 3) There was no interaction between the use of learning models with the Critical thinking skill towards student achievement, it is because FABcount <Ftable was 0.98 <0.04 which meant H0AB is accepted.

This PkM program aims to improve: (1) teacher skills in designing and developing KIT of Natural Sciences practicum tools, Practical tools, laboratory management SOP as well as integrated science materials with the potential of the surrounding environment. The method used in achieving these objectives is the implementation of inservice in the form of training and assistance. The training carried out is a training to develop the skills and creativity of science teachers in the production / design of an integrated natural science practicum device based on the environment and training to design learning using a scientific approach that utilizes the KIT of science that has been produced. Assistance is also carried out related to improving the ability of teachers to explore, elaborate and reflect on integrated science teaching materials. The output of this activity is in the form of KIT of integrated environment-based practicum tools equipped with SOP for the management of practicum with environmental conditions; Integrated practicum tools in integrated science learning (RPP, LKS, teacher's guide) to support scientific approach learning; Integrated science laboratory management SOP; Refresher teaching materials integrated science materials; Scientific article (national publication). The results of the activities that have been achieved include, increased understanding and skills of natural science teachers in the Jerowaru SMPN 1 Natural Science teacher group on integrated science material, increasing teachers' understanding of learning with an inquiry approach, increasing the skills of science teachers designing / making KIT Simple science made from raw materials from the surrounding environment to support science learning using the inquiry discovery approach (scientific approach), increasing the ability of science teachers to design learning tools with the inquiry inquiry approach (scientific approach), training the skills and abilities of science teachers in partner schools in implementing science learning with inquiry discovery (scientific approach) approach.
