Abstract

Lack of a variety of learning media was one of the issues contributing to poor student learning results in chemistry. One of the subjects that students found challenging was redox material since it involves complicated and abstract concepts that call for a thorough knowledge in order to grasp them. The goal of this study was to create educational materials on redox reactions with the help of Lectora Inspire. Up to 30 people participated in this study at SMA Negeri 1 Batang Kuis in class X, IPA 5. Research and development (R&D) was the approach employed, and the ADDIE paradigm, which has five parts (analysis, design, development, implementation, and evaluation), was used. At the analysis stage, needs and idea analysis were completed. The collection of analytical data was carried out using interview sheet and questionnaire. Furthermore, the learning media helped by lectora inspire was conceived and developed. The developed media was validated by media expert validators who were also material expert validators as many as 3 Unimed chemistry lecturers by providing questionnaires based on criteria following the National Education Standards Agency (BNSP), namely the feasibility of content, language, presentation, and graphics. In addition, to measure student learning outcomes utilizing pre-test and post-test questions. The results of the research at the analysis stage achieved in the chemistry learning process in students still tend to find it difficult to understand concepts and calculations in chemistry learning and students consider chemistry a boring topic. In addition, the findings of the material expert assessment were achieved with an average percentage of 92% with a very feasible category, media expert evaluation with an average percentage of 90% with a very feasible category. While the learning results were acquired from the average of N-gain value, which was 0.7 with the medium category, where the averages of pre test and post test were determined to be 35.33 and 80.33, respectively. Therefore, those had met the minimal completeness condition ≥75. Thus, the learning media helped by lectora inspire on redox reaction content has met the BSNP standard criteria and was suitable for use as a learning media and students learning outcomes might be improved.

Abstract

The purpose of this study is to analyze the perspectives of a university or college-level classroom learning instrument, the college and university classroom environment inventory (CUCEI), and then use it to compare students' actual and preferred perceptions of their classroom learning environments at the upper secondary and higher education levels. This study also examined differences in perceptions according to faculty and student expectations. A sample of 30 students participated in this study. The reliability of the modified CUCEI scale ranged from 0,28 to 0.88 for actual form and 0,65 to 0.94 for preffered form. When the two forms of instruments were compared, students in the first year of higher education had a perception of an actual learning environment that was less good than ideal in the cooperation dimension. Therefore, there is a need to improve the learning environment on the cooperation aspect.

Abstract

The Covid-19 pandemic has changed various community activities including in the world of education, where students and teachers are required to be able to adapt in life and be able to master essential material in every subject. Electrochemistry is a branch of chemistry that studies the relationship between chemical reactions and electrical energy, namely the transfer of electrons that occur. The material about electroplating is part of electrochemistry, namely about electrolytic cells, where students must know the reactions that occur at the negative electrode (cathode) and positive electrode (anode) as well as the solution used for gilding and the object to be plated. The complexity of the material in electrochemistry makes the teacher think hard how to make learning activities in class fun and memorable so that the learning material is remembered by students. One way to make learning activities in class come alive is to do practicum. In this study the authors carried out a different practicum from the previous year, namely gilding(electroplating)the metalbrought by the students and presenting the results in video form. The research subjects were 36 students of class XII IPA1 at MAN 10 Jakarta. Before practicum activities, the teacher gives Student Activity Sheets (SAS) so that students understand the steps of practicum activities to be carried out. In the implementation of practicum activities, it begins with the Pretest, practicum electroplating and making Chemistry wallmagazines and ends with the Posttest. At the end of the assignment, students make a video presentation of the results of the metal plating they have done by showing chemistry wall magazines andpractical explanations alsoanswers thequestions from the SAS. The final result obtained is that students enjoy learning activities and get increased results from pre to pot test from the average score 65 becomes 93,06, and have directed communication skills in video presentation based on the wall magazines they have made related to the concept of electrolytic cells.
