Abstract

This study aimed to assess high school student’s understanding of Banjarmasin by Rasch modeling, preci-sely the cognitive aspect. The research method was descriptive with a quantitative approach to assess the pattern of reactions and symptoms of Rasch data. According to the research findings, the person reliability (students) was +0.66 based on the Rasch modeling analysis, with the criterion satisfactory, indicating that the students knowledge was adequate. At the same time, Cronbachs’ alpha score had a value of +0.71 and met the criteria of excellent. In addition, the students with the highest level of understanding were coded 127P12B with a logit value (person measure) of 2.52 and average students with logit value of -0.77 or 0. In contrast, the students with low abilities were coded 030P10B and 059L11B (same logit value, -3.27 or 0). Other data were INFIT MNSQ and OUTFIT MNSQ (person) with average values of +0.99 and +1.14 (closer to 1, the better), while the INFIT and OUTFIT ZSTD values were -0.1 and 0.0 respectively (closer to 0, better). The most difficult question was Q16, which had a logit score of 1.96; students’ logit values carried this question. Students were regarded to have appropriate knowledge even though their ability excee-ded the problem ability. In conclusion, the Rasch model-based pre-learning evaluation was found to be useful in measuring students’ cognitive grasp of chemical bonding material. This study could serve as the primary reference for teachers in assessing students’ level of knowledge before they begin learning. In addi-tion to interpreting student knowledge through various Rasch data presentations, a study of the structure of questions with varying difficulty levels could be used to assess the full group of students’ understanding of chemistry.

Abstract

This study aims to analyze the effectiveness of e-learning media based on learning style in the form of e-posters, podcasts, and interactive videos on students' cognitive learning outcomes. This type of research is quantitative research. This study used a sample of 32 grade X PMIA 1 SMA Negeri 3 Banjarmasin students. This research uses Google Classroom as a platform for learning activities. Learning media in the form of e-posters, podcasts, interactive videos, and student learning outcomes can be downloaded and uploaded on Google Classroom. The research instrument used is a learning style questionnaire containing 30 statements. Data analysis in this study used a normality test, and Wilcoxon signed rank test. The cognitive learning outcomes of students with visual, auditory, and kinesthetic learning styles were 90.66%, 93.33%, and 87.33%, respectively, with ­N-gain  values of 0.75, 0.80, and 0.71. Based on data analysis, the results of this study show that e-learning media based on learning style is efficacious in improving the cognitive learning outcomes of students with visual, auditory, and kinesthetic learning styles. This learning style-based e-learning media can be applied to other chemical materials or subjects. The study employed-N-gain values to analyst the learning outcomes of the students. The - N gain values for students with visual, auditory and kinesthetic learning styles were 0.75, 0,80 and 0.71 respectively.  Overall, the data suggests that the learning outcomes of the students were quite positive and that the use of various learning media and Google Classroom as a platform can be effective in enhancing students learning outcomes.
