Abstract

Higher Order Thinking Skills (HOTS) are necessary skills to deal with the 21st century. This research aimed to develop a HOTS-based assessment instrument on acid-base for class XI that meets the aspects of validity, reliability, difficulty level and distinguishing power. This research is a Research and Development (R&D) study with a 4D model. The quality of the product was assessed by one material expert lecturer, one media expert lecturer, and four chemistry teachers of high school and tested on 30 science students in eleventh grade. The assessment of product quality obtained from material experts is 97.67% with the Very Good (VG) category; from media expert, it was 97.44% with the Very Good (VG) category; according to chemistry teachers, all items are feasible to be used as a field trial. After conducting the field trial, the product contained 18 valid items and 2 invalid items with the very reliable category, which was 0.899. At the difficulty level, the product had 11 easy items and 9 medium items. At the level of distinguishing power, the product had 1 very bad item, 2 sufficient items, 9 good items, and 8 very good items. Therefore, the resulting assessment questions instrument can be used to measure students' HOTS knowledge

Abstract

Website-based online learning media are needed by students to make it easier to understand multilevel representations of chemistry during the COVID-19 pandemic. This study aims to develop learning media based on google sites on chemical bonding material containing multilevel chemical representations and determine product quality. This media development adapts the 4-D development model, consisting of four stages: define, design, development, and disseminate. Quality assessment was carried out by material experts, media experts, chemistry teachers, and students responded. The research instrument was a product quality assessment sheet and student response sheets. The results showed that the quality of the media developed based on the assessment by the media obtained an ideal percentage of 97.5% in the excellent category, material experts obtained an ideal percentage of 85% in the excellent category, and chemistry teachers obtained an ideal percentage of 97% in the excellent category. Learning media based on google sites on chemical bonding material containing multilevel chemical representations also responded positively with a percentage of 93.75%. It can be concluded that the developed media is suitable for use in the learning process to improve students' multi-representation abilities on chemical bonding material.

Abstract

The competence to make synthetic indicators is terribly required by chemistry teachers in high school in order that the implementation of practicum can run more effectively and efficiently. This study aimed to develop a practicum video on how to make synthetic indicators and find out the quality of the developed video. This study was a Research and Development (R&D) study with 4D development model (Define, Design, Develop, and Disseminate). The product was a practicum video on how to make synthetic indicators, in the form of MP4, containing the creation of phenolphthalein, starch, Tollens, and Fehling indicators. The product was assessed by one material expert, one media expert, and four reviewers (high school chemistry teachers). The results of product assessments based on quality, from media expert, it got a percentage of 96% in the very good category; from material expert, it got a percentage of 95% in the very good category; and from reviewers, it got a percentage of 98.33% in the very good category. Furthermore, the video was also responded very well by prospective chemistry teachers with an ideal percentage of 98%. Based on the results, it can be concluded that the developed product is feasible to be used in the learning process to improve the ability of prospective chemistry teachers to make synthetic indicators in the laboratory
