Abstract

The implementation of HOTS in the learning process is considered capable of improving the quality of education in Indonesia. However, in online learning conditions, there are many obstacles and limitations to training HOTS in Biology lesson. This study aims to describe biology teachers' knowledge, preparation, and implementation of HOTS training during online learning. This study uses a qualitative approach to the type of phenomenology. This study involved 12 Biology teachers at SMA and SMK in West Java. The data collection technique is carried out through interviews via WhatsApp Call. The data analysis technique used is through reduction, data review, and conclusions drawing. Based on the results of data analysis, it was found that the teacher’s understanding of HOTS learning is still weak, and the implementation of HOTS training during online learning is still not optimal. The most widely used learning model is Problem based Learning. The constraint implementation of online HOTS training is inseparable from the online learning barriers, but teachers also continue to try to handle these barriers with various solutions.

Abstract

Assessment of science process skills can be conducted through tests or non-tests. However, observations, as one non-test technique, often face challenges related to space, time, and evaluator resources. A polytomous-type paper-and-pencil test was developed to address these issues. Item characteristic analysis is an essential aspect of instrument development; thus, this study reports the instrument analysis within the development of this assessment, using the item response theory approach. A total of 415 high school students in Sumedang completed 30 items depeloved. They came from four high schools selected based on the 2022 Asessmen Kompetensi Minimum (AKM) criteria. The test of 30 items had previously undergone successful content validity, construct validity, and reliability tests. Based on the item response theory assumptions, all items were eligible for analysis using this approach. Item fit testing revealed that the instrument suited the Generalized Partial Credit Model (GPCM). The analysis was performed using the R Program application. Results showed that all items (100%) were medium difficulty; 21 items (70%) had good discrimination and items (30%) exhibited high discrimination. 14 items were suggested for category reduction due to minimal delta differences or exceedingly low delta values. These findings emphasize item analysis to achieve high-quality instruments.

Abstract

This study aims to develop an assessment instrument for measuring science process skills among 10th-grade high school students in Biology. The research adopts a quantitative approach, involving a sample of 415 high school students from Sumedang Regency. Participants were selected from four high schools based on the 2022 Minimum Competency Assessment (AKM) evaluation criteria. Data analysis included content validity using Aiken’s V and construct validity through Confirmatory Factor Analysis (CFA). A total of 36 items were validated by six experts, including measurement specialists, subject matter experts, and high school Biology teachers. Based on the validators’ feedback, several items were revised, and one item was removed, resulting in 35 items being tested. The Aiken’s V validity index was >0.78. trial data were used to establish construct validity, with CFA tested against Goodness of Fit criteria, including GFI, RMSR/RMR, TLF/NNFI, CFI, IFI, AGFI, and RMSEA. After model modification, all items met the fit criteria of 30 items, proven valid for assessing science process skills among 10th-grade high school students in Biology.
