Abstract

During the Covid-19 pandemic, SMA Negeri 1 Cangkringan was one of the schools that implemented online learning methods. However, in practice, there are many obstacles experienced by students such as students feeling heavy and difficulty understanding the material, piling up assignments received by students, the emergence of fear in students about their academic progress, a sense of failure in achieving the expected targets, pressure to be able to learn independently, demands high concentration in paying attention to the teacher's explanation during the learning process which is often constrained by signals so that the teacher's voice is not heard by students, tired and worried about piling up assignments, pressure from parents, and students are not used to the assignment deadline. This condition makes students stressed with their academic life. Therefore, the Gotalty application was developed as a medium for educators to identify problems in online learning faced by students and assist students in maintaining a balance between psychological conditions and academic conditions during the learning process. The program implementation method is carried out by applying the PDCA method (Plan, Do, Check, and Action). The results obtained based on the program that has been carried out, namely the Gotalty application can help relieve anxiety about the problems experienced by students during online learning, and increase students' knowledge of mental health which shows that the psychoeducation process has been successfully carried out, and increases awareness of mental health. Very helpful features for program partners are motivational videos and psychology articles. This is evidenced by the results of the pretest and post-test. In addition, this program also produces outputs in the form of program implementation guidebooks, partner pocketbooks, and program implementation videos.

Abstract

Chemistry is studied by students at the high school level. However, due to the abstract concept of chemistry, chemistry becomes difficult for some students to learn. One problem with studying chemistry is the petroleum material in online and offline learning systems. This study aimed to determine the feasibility and practicality of interactive learning media based on the 3D augmented reality of petroleum topics. This study aims to describe the making of applications with augmented reality technology as a medium for learning chemistry. The research type was development research that adopted a 4D model (define, design, develop, disseminate) but was limited to the development stage. The population in this study was 192 students of public high school SMAN 7 Mataram, Indonesia. This study's sampling was carried out using a random sampling technique measured through an expert validation sheet with three assessment aspects assessed by three validators.

Abstract

Science subjects, or specifically biology, contain many concepts and terminologies that require extensive effort in memorizing. As a result, students are employing their own learning styles to learn things in the best possible way. Thus, this study aimed to investigate the possible relationship between the students’ retention level in biology and learning styles in the course. A descriptive-correlational research design was utilized to determine the relationship between the retention level and learning styles of Grade 10 students in biology. A retention test was conducted that seeks to evaluate the retention level of the respondents in their biology subjects. Respondents were asked to select the best way on how they are learning biology effectively, as part of the retention test. Each of the ways indicated corresponds to a specific learning style category following the Visual, Auditory, Read, and Kinesthetic (VARK) Learning styles Model. Findings revealed that the majority of the respondents were Visual Learners comprised of 51.61% of the population and a portion of 38.71% of the respondents have an Outstanding Level of Retention in basic biology concepts and terminologies. In addition, the overall retention level category of the population is with Satisfactory Level of Retention, which was based on their mean percentage score. Furthermore, it has been proven that there is none to very weak relationship between the retention level and learning styles of the respondents where it gained a correlation level of 0.151, on which correlation is significant at 0.01 level, which strength of the linear relationship is categorized under none to the extremely weak relationship. It has been concluded that many factors, aside from learning styles, may affect the students’ retention of learning biology.
