ChatGPT is largely acknowledged for its substantial capacity to enhance the teaching and learning process despite some concerns. Based on the available literature, no study compares groups of students using ChatGPT and those who did not, more so in programming. Therefore, the main goal of this study was to examine how ChatGPT affects SHS students'…

In the 2021 legislative session, the Tennessee General Assembly enacted Chapter 170 of the Public Acts of 2021 (PC170, now codified as T.C.A. § 49-6-1012), which requires all Tennessee local education agencies (LEAs) and public charter schools to adopt an academic acceleration policy for grades 7-12 and establish criteria for student enrollment in…

Students' worksheets, as learning material, is important to achieve learning outcomes. This study aimed to develop students' worksheet, based on STEAM (Science, Technology, Engineering, Art, and Mathematics), on ecosystem topics to empower students' science process skills. The Research and Development used 4D model by Thiagarajan. Students'…

Twenty-first century chemistry education researchers reported challenges in chemistry education pertaining to high school chemistry teaching-learning outcomes. Even though all studies intended to improve chemistry teaching-learning outcomes, unfortunately the impact of chemistry education research found not to be much encouraging. A few of these…

The Physics Laboratory of the Hellenic Open University has constructed a small scale and low cost air shower detector suitable for operation inside the classroom or school laboratory ([mu]Cosmics detector). In this work we present some of the educational activities foreseen with the [mu]Cosmics air shower detector, as well as the assessment of a…

A two-week summer camp for high school students focused on sustainable polymers was developed and implemented. Students took part in experiments and interactive lessons that demonstrate polymer chemistry fundamentals alongside associated sustainability challenges and opportunities. For example, polymer concepts related to chemical properties…

An easily constructed and inexpensive polarimeter with an optical rotation angle resolution of about 0.5° is presented. It is made from small pieces of polarizing film, 2 LEDs, a protractor, and a few wires, all held in place with plastic interlocking toy bricks, such as Lego bricks. The instrument was used to demonstrate the optical rotation of…

Secondary science education plays a key role in students' process to become scientifically literate citizens. However, teaching students to acquire the necessary skills and knowledge to deal with complex societal issues is challenging. This paper reports about a study in which Scrum -- a methodology to manage complex projects -- was implemented in…

Students often need to obtain, organize, clean, and analyze data in order to draw conclusions about a particular phenomenon (e.g., why tidal heights change). When conducting a science investigation in biology, chemistry, physics, or Earth science, data can be collected by the student or can be provided to them via secondary data sets. This article…

New notions of science teaching and learning provide challenges for designing and using classroom assessment. Existing assessments are not effective in assessing and supporting desired science learning because they are not designed to capture and aid such learning (NRC 2014; Pellegrino 2013). In addition, it is important to evaluate effectiveness…

Science explanation videos, especially online ones, have become popular. They cover nearly all topics from school science curricula. Teachers use them in a flipped classroom. Students watch them also in their leisure time. However, there is a lack of research on guidelines that effective science explanation videos should follow. The research on…

In order to investigate students' misunderstandings of potential wells and tunneling, a conceptual knowledge test was administered to Dutch secondary school students after they were taught about quantum mechanics. A frequency analysis of responses to the multiple choice questions (n = 98) and coding of the responses to the open-ended questions and…

Following on earlier examinations of biology high school textbooks' handling of race, this study examines eleven biology textbooks, intended for US high school use and published between 2014 and 2019. It offers a close reading of these textbooks' treatment of four topics that have been associated with race: genetic disorders, human origins, skin…

The present study ascertains the effectiveness of the Think-Pair-Share (TPS) Cooperative Learning Model over the lecture-based conventional teaching of Environmental-Science (EVS) on a sample of 78 students at the secondary level. Pre-test-Post-test Intact group design was adopted for this purpose. TPS Cooperative learning Instructions were…

The interdisciplinary subject of agricultural biochemistry can provide an abundance of didactic opportunities for educators teaching biochemistry and molecular biology in secondary-level science courses. This is especially true in present times when virtual-learning strategies supersede in-person instruction and contemporary approaches are needed…
