The use of red cabbage ("Brassica oleracea var. capitata F. rubra") extract as a pH indicator is a versatile and popular demonstration that is employed by educators in many schools and universities. Previous variations of this demonstration have used red cabbage extracts to prepare paper that changes color when solutions of acid or base…

This paper aimed to examine the changes in the representations of nature of science (NOS) in Chinese senior high school chemistry textbooks under the influence of the new curriculum ideas. The study was conducted based on an analytical framework in which the aspects of NOS, the approaches to address NOS, and the content relation of NOS aspects…

Scientists have always been fascinated by transient far-from-equilibrium systems. Since the (early) 1970s, there have been literature reports on the implementation of didactic experiments as a tool for attracting and stimulating students' and general public interest. In this work, a group of 12 high school students, supported by their chemistry…

Justice-centred science pedagogy has been suggested as an effective framework for supporting teachers in bringing in culturally relevant pedagogy to their science classrooms; however, limited instructional tools exist that introduce social dimensions of science in ways teachers feel confident navigating. In this article, we add to the…

This case study used a design-based research approach to examine the development and evaluation of an online homework system to support learning and problem-solving in a high school physics course. Emergent themes included challenges of building the system, strengths and weaknesses of it, and the benefits to students. While the system largely met…

This study uses high school transcript data from the National Assessment of Educational Progress (NAEP) High School Transcript Study (HSTS) to determine the validity of student-reported high school courses on the NAEP twelfth-grade student questionnaire. Given that the HSTS is not administered as part of every NAEP twelfth-grade assessment,…

The aim of this study is to examine whether reading habits have any effects on the academic achievement of the biology course of high school students in Turkey. In the research, the relational screening model was preferred from the quantitative research models and the phenomenological approach was preferred from the qualitative research models, so…

The COVID-19 pandemic stimulated education system worldwide to employ online learning to support learning despite difficult times. To respond to this challenge and to promote Sustainable Development Goal (SDG) 4, advocating quality education, a virtual learning material (VLM) for Biology was articulated in Google Classroom. Accordingly, this study…

Last month we highlighted our Quadrennial Survey of High School Physics Teachers. Using data from the survey, we have looked at the availability of high school physics. We report that about 95% of high school seniors attend a high school where physics is offered regularly--either every year or every other year. A U.S. Department of Education…

Through STEAM education, this action research aims to improve senior high school students' ability to think critically and learn effectively. The target group for this study consisted of 36 senior high school students from one school in Thailand. A STEAM education lesson plan, a test of productive thinking, and a test of learning achievement were…

In this study with high school students, a descriptive scanning model, one of the qualitative research methods, was used to determine the extent to which the achievements of the hybridization occurred. The study was conducted with 12th grade students studying in a public high school in Bursa in 2017-2018 academic year. According to the findings…

Research has highlighted difficulties experienced by students when studying quantum physics in introductory courses. In this paper, we present a teaching and learning sequence (TLS) aiming at introducing a quantum model of emission and absorption of radiation and we assess its impact on the students' learning about atomic spectra. The TLS has been…

Background: A multimedia software designed as a Computer-Assisted Scaffolding system was used to teach gas behavior on the submicroscopic level using Physics Education Technology Project (PhET) simulation. PhET is a set of interactive, research-based science and mathematics online simulations (https://phet. colorado.edu/). Purpose: The purpose was…

The High School Summer Research Program (HSSRP) is a rigorous eight-week research experience that challenges high school students to a novel scientific question in an engineering laboratory at the Henry Samueli School of Engineering and Applied Science (HSSEAS) at the University of California, Los Angeles (UCLA). The program collates highly…

The paper reports a study that focussed on investigating the effectiveness of Toulmin's argument pattern (TAP) within Think-Read-Group-Share-Reflect (TRGSR) scientific argumentation strategy on higher secondary students' critical thinking. A quasi-experimental, pretest-posttest-control group design was deployed. The subjects were 50 twelfth grade…
