Development of High Order Thinking Skills (HOTS) Test Instruments on Thermochemistry Topics

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.

Reflections on Teaching and Learning Chemistry Through Youth Participatory Science

This chapter captures a panel discussion from the 2019 conference of Science Educators for Equity, Diversity, and Social Justice (SEEDS, http://seedsweb.org) in Norfolk, Virginia. The panel included two high school students, three high school chemistry teachers, a community organizer, an administrator for a large urban school district, and a university-based science educator. These panelists, the authors of this chapter, had been collaborating on an initiative to support youth participatory science (YPS) projects in high school chemistry classes. We share this lightly edited transcript of our conversation as a way to communicate perspectives about the opportunities and challenges of YPS from viewpoints across these constituency groups. Our conversation is organized around three questions for reflection: (1) What are some of the challenges and possibilities when it comes to engaging with YPS in science classes? (2) How has engaging in YPS exposed both insights and oversights of scientific ways of knowing? (3) In YPS, what are the relationships between learning science and engaging in political and community issues?

Anales de Química, la Revista de la Real Sociedad Española de Química – The Magazine of the Spanish Royal Society of Chemistry

: Anales de Química de la Real Sociedad Española de Química is the flagship journal of the Spanish Royal Society of Chemistry (RSEQ). Anales currently publishes different types of articles including essays, interviews, opinion, and review articles written for readers (scientists and teachers) who are not specialists in the field. The journal has a special focus in didactics and history of chemistry. A substantial part of its content is directed towards high school chemistry teachers. An overview of the history of the journal together with its current activities, as well as a brief history of the RSEQ are presented.

Teaching Design of "Properties of Sodium" based on the Core Literacy of Chemistry

The learning of sodium and its chemical compounds are the beginning of systematic learning of elemental compounds in senior high school, and have a vital influence on senior high school chemistry learning. This paper is about the teaching design of the first class --the properties of sodium. Based on the five core qualities of chemistry, it adopts the method of situational teaching, gives prominence to the connection and transition among knowledge points, and sets up multiple experiments and group discussions to guide students to construct and form their thinking pattern in chemistry and scientific thinking methods.

Learning Media Design based on Traditional Game of Tumbu-Tumbu Belanga (T2B) on Salt Hydrolysis Topic

This research aimed to test the validity of the feasibility of traditional game learning media on salt hydrolysis. This research was development research (R&D) with a qualitative descriptive approach. This research uses the ADDIE model development design, which consists of 5 (five) stages, namely (1) analysis, (2) design, (3) development, (4) implementation, and (5) evaluation. Data collection techniques in this study used a validation sheet for the assessment of the feasibility of tumbu-tumbu learning media. The tumbu-tumbu learning media validation wass assessed by 4 expert validators, namely 2 chemistry lecturers of State University of Gorontalo material experts, 1 media expert lecturer, and 1 high school chemistry teacher. The results of the validation of tumbu-tumbu learning media development obtained an average percentage 0f 89.40%, which was categorized in very feasible criteria. Therefore, the tumbu-tumbu learning media are highly usable in the learning process of salt hydrolysis.
