Abstract

A study has been conducted on the influence of web-based learning media Wordwall on student learning outcomes in thermochemistry material at SMA Kosgoro Tomohon. The research method used is Pretest-Posttest Control Group Design, involving 15 students of class XI A as the experimental class and 15 students of class XI B as the control class, while the t-test is carried out. Wordwall media is applied in the learning process to improve student understanding and involvement interactively in the experimental class. Based on the results of the study and discussion, it shows that the use of Wordwall has an effect on student learning outcomes, as shown through the research data, namely the average value of the experimental class of 76.19 is higher than the control class with an average of 65.96 and continued with a t-test with the help of SPSS software, a significance level value of 0.012 <α (0.05) was obtained. Therefore, this study shows a significant influence between Wordwall web media on student learning outcomes in thermochemistry material at SMA Kosgoro Tomohon. Therefore, Wordwall learning media is recommended as an innovative alternative to support the learning of complex chemical materials such as thermochemistry.

Abstract

This study aims to determine the effect of applying Chemo-Entrepreneurship (CEP)-based chemistry learning on students' engagement and learning outcomes in the buffer solution material for Grade XI students at SMA Citra Kasih Manado. This research employed a Classroom Action Research (CAR) method conducted in two cycles, each consisting of planning, implementation, observation, and reflection stages. The research instruments included student activity observation sheets and learning outcome tests. The results showed that the application of CEP-based learning significantly increased students' engagement and learning outcomes. The average learning activity score increased from 42.5% (categorized as low) in the first cycle to 90% (categorized as very good) in the second cycle. The average learning outcome score also rose from 56 in the first cycle to 89 in the second cycle, achieving a 100% mastery level. The implementation of Chemo-Entrepreneurship through a research-based learning model proved effective in enhancing student engagement, creativity, and understanding of buffer solution concepts. Therefore, this approach is recommended for use in other chemistry learning topics to foster entrepreneurial potential and 21st-century skills among students.

Abstract

This research is a preliminary study of the development of blog-based reaction rate e-module media to increase student learning motivation and communication which was carried out by R&D. This study is a mixed-method of descriptive qualitative and quantitative methods. Data was collected through library research and questionnaires which were processed using the Rasch Model. The results of data collection were then processed in a qualitative descriptive manner. The purpose of this study is to find out, describe and explain the need for blog-based e-module development on the subject of reaction rates and the advantages and disadvantages of blog media. The literature study was carried out by reviewing journals relevant to the research (library research) and questionnaire data collection was carried out online using the Google form. Based on the results of the questionnaire analysis for the development of blog-based reaction rate e-modules to increase student learning motivation and communication using the Rasch Model, the results obtained from reviewing journals and distributing questionnaires can be concluded that blogger media is classified as effective for use as an alternative learning media for students because it is easy to use, inexpensive and interactive. The use of blog media is able to increase student learning motivation because of the in-depth presentation of material. The advantage of using blog media compared to print media is the sub-microscopic presentation. The blog-based module is able to describe abstract sub-microscopic materials on reaction rates in detail and is not boring because it is animated. Along with the development of learning motivation, students’ mathematical communication and communication in the learning process will increase.
