This research aims to develop a Pictorial-based Two-Tier Multiple Choice Misconception Diagnostic Test on Buffer Solutions. This research uses the Development and Validation method. The development steps in this method consist of test development (design); validity and reliability test; development of determination key; use of tests, and analysis of results. Based on the content validity test using the Content Validity Ratio (CVR) method, there are 24 items meet the content validity criteria. Based on the reliability test obtained Cronbach's Alpha value of 0.827 which indicates that the developed test is included in the acceptable category. It can identify high school students' misconceptions about the buffer solutions because the presence of pictures can help students understand the problems about the buffer solutions, and can provide an overview of their mental representations so that misconceptions are revealed more deeply.

This research aims to develop Higher Order Thinking Skill (HOTS)-based test instruments on thermochemistry in the form of a valid and reliable multiple-choice question. This research applied Research and Development (R&D) design by using the development model of Borg & Gall. The respondents of this research were 55 high school students which came from nine different schools. The research objects were multiple-choice HOTS questions numbering 20 questions. The research data was obtained by validating the thermochemistry HOTS questions by material and media expert lecturers. High school chemistry teacher as a reviewer who assesses the questions and tested on students. The results showed that the product quality assessment by material expert 92.00%; product quality assessment by media expert 92.00%; and quality assessment by reviewers (high school chemistry teachers) 94.89 % in the Very Good category. The trial result data from the students were processed by using IBM SPSS Statistics 24 and it showed that nine questions were valid but not reliable.

The purpose of this research is to describe the stages of developing and validating a product which includes content validity and constructs validity. The method used is Research and Development (R&D) with define, design, develop, and disseminate (4D) model. The initial product was validated by material and learning evaluation expert lecturer. The suitability of the items evaluated by chemistry teacher based on indicators of competency achievement. The sample selection was determined by stratified random sampling of 170 students of 11th grade senior high school in Yogyakarta City. Content validity was analyzed using Aiken's V formula. The results of data analysis show that all components of the test instrument are valid with Aiken's V value greater than 0.80 with a significance of 0.05. Verification of construct validity was analyzed using exploratory factor analysis with the help of the SPSS version 21.0 program. The results prove that all components in the integrated assessment instrument are suitable to be used to measure the critical thinking skills and self-efficacy of students on acid-base concept.

Scientific literacy is an ability that must be had by pre-service teachers. This research aimed to find out the scientific literacy's ability of pre-service teachers in chemistry education. This research was descriptive with quantitative approach. Participants were taken by simple random sampling techniques, the participants are chemistry education students. The data source comes from scientific literacy tests with socio-scientific issues and open-ended question description tests. The validity of the data was tested using a data triangulation technique, in which researchers compare data obtained through test instruments and interview results. The results of the data analysis showed the scientific literacy of chemistry education students was dominant in the nominal and functional categories with a percentage of 33.2% and 24.2%, conceptual and multidimensional categories 13.7%; 4.4%; and 24.5% of students did not give answers the tests.

Secondary metabolites are part of the discussion of Natural Product Organic Chemistry which demands a practicum process in lectures. This research aims to determine process skills through the application of inquiry-based worksheets on secondary metabolite analysis of three types of Indonesian medicinal plants. In the worksheet, there were several expected goals, including developing students' abilities in designing experiments, conducting experiments, and communicating both orally and in writing. The method used in this research was a One-Shot Case Study with 18 students taking Natural Product Organic Chemistry courses. The instruments used were learning descriptions, inquiry-based worksheets, observation sheets, assessment sheets (psychomotor, presentations, and reports). The results of the worksheet application showed that the students' ability obtain an average value of 84.15 with a very good category. The ability to design experiments, conduct experiments, and communicate orally and in writing obtained results of 77.16 (good categories), 92.50 (very good), and 82.80 (very good), respectively. This inquiry-based worksheet can be used in the study of Natural Product Organic Chemistry, especially in secondary metabolites.

This research aims to development a REACT-based e-worksheet that is feasible to use to stimulate the critical thinking, creativity, collaboration, communication (4C) skills and determine student response. The challenges of a dynamic era require students to have a 4C skills set critical thinking and problem-solving skills; creativity and innovation; communication; and collaboration. One of the tools that can be used in online learning to achieve this goal is to use the electronic Student Worksheet (E-Worksheet) which includes the student's 4C skill values with REACT strategies: Relating, Experiencing, Applying, Cooperating, and Transferring. The research chooses one of the topics in chemistry, which is introduction to chemistry and laboratories. This REACT-based e-worksheet was developed using the ADDIE development model which consists of five stages those are analysis, design, development, implementation, and evaluation. In addition, the study used a sample of 10 students of mathematic and natural science 12th grade MAN 4 Tangerang. Based on the results of validation and student response questionnaires, REACT-based e-worksheet to stimulate students' 4C skills was declared valid and obtained an average percentage of 91.8% with very good criteria.

This study analyses students learning outcomes and internalization of Islamic values in buffer solutions through online learning during the Covid-19 pandemic. The study was conducted to find effective strategies in achieving students’ competence and Islamic values. This research is a quasi-experimental study conducted on 100 tenth-grade students using The One Group Pretest-Posttest model. The results showed students learning outcomes obtain an N-Gain value of 0.72 (high category). The internalization of Islamic values for three aspects: praying, blessing, and study hard determined the average above 3 (often do). Thus, the research concludes that online learning conducted on buffer materials is effective in mastering the content and internalization of Islamic values.
