Development of Electronic Student Worksheet Using Problem-Based Learning Model with the Wizer.me Platform on Momentum and Impulse Materials

– This research departs from the problem of limited tools and practicum materials in the laboratory, and students need help understanding the concept of momentum and impulse material. An effort to overcome these problems is to develop an electronic student worksheet using a problem-based learning model with the Wizer.me platform. This study aims to describe the development process, validity level, and practicality of electronic student worksheets using the problem-based learning model with the Wizer.me platform on momentum and impulse material. The research method used is research and development (R&D) with the ADDIE development model. The population of this research is all class X MIPA SMA Negeri 13 Garut, consisting of seven classes with 252 students. The research sample was taken by using the cluster random sampling technique for classes X MIPA 1 and X MIPA 2, with 36 students in each class. The data analysis technique used in processing the validation results was Aiken's V index. The results showed that the Aiken index of material, media, and learning experts were respectively 0.91, 0.94, and 0.96 with excellent categories, and the average practicality percentage is 89% with efficient criteria. Therefore, it can be concluded that the electronic student worksheets developed using a problem-based learning model with the Wizer.me platform on the momentum and impulse material meets valid and practical criteria for use in the learning process.


I. INTRODUCTION
Student Worksheets (SW) is a learning media that educators can use to increase the involvement or activity of students in the teaching and learning process (Diana & Makiyah, 2021;Ika & Doa, 2021;Warnida et al., 2023). SW serves to provide more understanding regarding the material provided by educators because it contains essential and interactive elements that are useful for attracting or motivating students (Ragilia et al., 2018;Sa'diah et al., 2022). The SW contains several questions, preparations, and activities that students must carry out. SW can develop S. Septiana, R. Rizal, Y. S. Makiyah | JPF | Volume 11 | Number 2 | 2023 | 202 -214 203 students' process skills which are expected to be able to build their knowledge structure from the data they obtain through direct involvement in observation (Safitri et al., 2022). According to Isnaini et al. (2019) Developing worksheets that use technological models will further motivate students and make it easier to facilitate the learning process.
In addition, another advantage of having SW using technology models is that it can be inserted videos, images, audio, and practicum simulations, has an attractive appearance, can be accessed anywhere and anytime, and can provide feedback, corrections, and grades automatically (Pabri et al., 2022).

Based on the results of interviews with
Physics educators and an analysis of the needs of students at SMAN 13 Garut.  (Diana & Makiyah, 2021;Nurazmi & Bancong, 2021). The implementation of the PBL model consists of 5 process stages: student orientation to problems, organizing students, conducting investigations, presenting data, and analyzing and evaluating (Lespita et al., 2023;Pratiwi et al., 2019;Zhou, 2018).
Electronic Student Worksheets (ESW) using the PBL model has the potential to help create fun learning and improve problem-solving abilities that occur in students' daily lives (Muslem et al., 2019;Nasar & Kurniati, 2020 Table 1, and qualitative data is in the form of input, suggestions, and comments. (1) Information: = Respondent's agreement index regarding item validity = The score set by the respondent minus the lowest score ( = − 1) = Choice category score on the respondent = Number of respondents = The number of categories filled by respondents Information: Y= Score given by students X= Maximum score To find the percentage of the overall score obtained using the formula: Information: Y= Score given by students X= Maximum score N= Many Students The calculation results were then interpreted based on the product practicality criteria table in Table 3. shows the intro and contents of the ESW presented in Figures 2 and 3.    These results indicate that the developed ESW is good in terms of format, appearance, and interactivity. According to Pratiwi & Margunayasa (2022), In making ESW and compiling content, it is also necessary to pay attention to interactivity, layout, and appearance design to make it attractive. The specialty of ESW using the PBL model has the potential to help create fun learning and improve problem-solving abilities that occur in students' daily lives (Fitriyani et al., 2019;Zulfawati et al., 2022).
