The Development Higher Order Thinking Skill (Hots) As Questions In Chemistry Study (Solubility And Solubility Product Constant)

The significance of critical thinking as one of the 21st century skills makes the Indonesian Ministry of Education and Culture integrate Higher Order Thinking Skill (HOTS) in the latest national curriculum. Students critical thinking skills to working on HOTS assessment are fundamental, especially in learning chemistry lessons. The research purpose is to analyze the quality of HOTS chemistry questions/ assessment and to observe the teachers and students responses to computer-based test instruments developed using Wondershare Quiz Maker Software (WQM). The research method used Research And Development (R & D) Borg & Gall model. The sample was determined by Random Sampling Technique in total 104 students from several high school in Banda Aceh, it is SMAN 4, SMAN 5, SMAN 8 and SMAN 11. The data analysis technique was through calculating the percentage score of the assessment quality and analyzing the question items quantitatively such as validity, reliability, difficulty level of the questions, differential question power tests and distracting question power using proanaltes. The results showed that the quality of HOTS in chemical questions tested (for the solubility subject and the solubility product constant in terms of qualitative analysis of the items) in the validation test gained average score, it is 98.1%, means the items are qualified categories. In terms of quantitative analysis question items, it reached 95% valid and 5% invalid and the reliability test score was 0.740, are in high category. The questions difficulty covers 95% medium and 5% are in difficult level. The questions differential power for each category is 65% good, 30% medium and 5% less. The teachers and students response to the development of the computer-based HOTS test instrument using WQM software was positive and show good result. The teacher response positively on score strongly agreed was 83.3% and agreed 16.7%, while the students response on score strongly agreed was 27.2% and 63.3% agreed. The research conclusion there is significant students critical thinking skills improved (in learning the solubility and the solubility product constant chapter) by using HOTS assessment using Wondershare Quiz Maker software.

The Correlation Analysis Between Critical Thinking Skills And Learning Outcomes Through Implementation Of Guided Inquiry Learning Models

The 21st-century learning process highlights the critical thinking skills concept. Critical thinking has the highest chance of impacting students' learning outcomes. One of the learning models to increase critical thinking skills was guided inquiry. This research aimed to analyze the correlation between critical thinking skills and learning outcomes on reaction rates topic using the Guided Inquiry learning model. This research used a correlational design. Subjects were students of SMA Negeri 1 Krian class XI MIPA 6 odd semester in the academic year 2020/2021 as many as 34 people. The data were obtained using the observation sheets instrument for the implementation of the guided inquiry learning model, the critical thinking skills test sheets, and the learning outcomes test sheets. Data were analyzed using Pearson correlation and linear regression analysis used (α) 0.05. The results indicated that there was a significant positive correlation between critical thinking and learning outcomes on reaction rates topic using the Guided Inquiry learning model. The correlation regression equation obtained between the two variables is Y = -16.575 + 1.170X with reliability value 76,3%. The N-gain score obtained for each indicator of critical thinking skills and learning outcomes ≥ 0.7 at high criteria.

Critical thinking ability of high school students in daily life acid-base concept

This study aimed to comprehend the quality of critical thinking questions and measure the critical thinking ability in the daily life acid-base topic of 2nd -students from six public high schools, six private high schools, and combination of them in Yogyakarta at the 2018/2019 academic year based on the answer patterns of students to the developed critical thinking questions. The method was an ex-post facto research designed with a one-sample design. The level of critical thinking ability was measured by 15 critical thinking question outlined from the seven critical thinking criteria referred to established commercial critical thinking test.

Needs Analysis of Problem Solving Based Learning Video Development to Train Students' Concept Understanding

Students' understanding of concepts is a very important factor in the success of learning. But in reality, Indonesian students' conceptual understanding is still low. The factor of low understanding of students' concepts is because students are not actively involved in problem solving activities. Student involvement can be trained by using one of the communication tools in the form of interesting learning videos to get students' attention in learning activities. This research is a survey research as a first step in developing problem solving learning videos. The benefit of this research is to find out what students currently need in science learning and how much students need to develop problem solving based learning videos. The subjects used in this study were junior high school students with a sample size of 48 students selected based on a region. This needs analysis includes 4 indicators, namely a) analysis of learning problems; b) analysis of learners; c) analysis of objectives; d) analysis of settings. Based on the results of this study, information was obtained that the development of problem solving based learning videos was feasible to be developed as a science learning media to train students' conceptual understanding in the city of Pekanbaru
