The biology laboratory at State Senior High School (SSHS) 1 of Rasau Jaya has not been fully utilized, necessitating evaluation and improvement. This study aimed to determine the suitability of laboratory facilities and infrastructure at SSHS 1 of Rasau Jaya in relation to the existing standards set by the national regulations. This is a…

Significant figures in a measurement are all the digits known plus one more digit that is uncertain or estimated. The problem addressed by this study is inconsistencies in the instruction of significant figures in high school chemistry. This study examined teacher experience as related to the teaching of significant figures. The individuals…

This research paper aims to propose a novel didactic sequence inspired by an historical/epistemological study of the evolution of spectroscopy and in particular of colorimetry. The working principles of the historical color comparators and the visual color matching method, first proposed by Duboscq, stimulated us in the development of a five-step…

There are conflicting reports not only on the effect of scientific inquiry on academic achievement but also insufficient evidence on the relationship between understanding the nature of scientific inquiry and academic achievement; more generalizable studies are needed. The purpose of this large sampled study was to investigate the middle school…

Studies of both professional science practice and children's science learning show that care is not merely ancillary to disciplinary work but a core and generative constituent of science practice. In science education research, however, students' care is often overlooked. In this paper, we describe the expression of care across two STEM classrooms…

High school students and students in the first years of college have difficulties in understanding the topic of stoichiometry and, in particular, the concept of limiting reactant. Proposals aimed at overcoming these learning obstacles tend to focus on analogies, and there are few sequences that approach teaching from an experimental perspective.…

Understanding the photosynthesis concepts is challenging due to its abstract nature, often leading to student misconceptions. This study aims to identify and analyze misconceptions among science and social studies students using the image analysis method. A total of 78 students (32 science, 46 social studies) participated, selected through a…

This study analyses the effectiveness of directed vs. minimally directed inquiry-based instructional approaches in improving students' attitudes toward physics. It specifically compares the impacts of cognitively guided instructional strategy (CGIS) and Cubing instructional strategy (CIS) on student attitudes. Using a pretest--post-test…

Holism evolution states that although energy, matter, life, consciousness and the human personality are independent and different substances/levels of evolution, they are holistically and intimately related. This paper presents the findings from teaching chemistry to high school science students and post-graduate university science-education…

The purpose of this study was to explore instructional designs for promoting inquiry practices in secondary school textbooks. Three criteria were employed to select the textbooks: (1) approved by the Ministry of Education in Singapore and the Ministry of Education and Culture in Indonesia, (2) used in secondary schools, and (3) included content…

Drawing upon the model for science teacher assessment literacy developed by [Abell, S. K., & Siegel, M. A. (2011). Assessment literacy: What science teachers need to know and be able to do. In "The professional knowledge base of science teaching" (pp. 205-221). Springer. https://doi.org/10.1007/978-90-481-3927-9_12], this study…

Science should provide students an accurate and contemporary education on genetic influence, particularly how it impacts trait variability and developmental norms. Stories involving familial, racial, and sexual differences routinely appear in the popular media and sales of over-the-counter genetic tests are mounting. Unfortunately, research…

The activity proposed in this study aims to investigate the equilibrium between the liquid and vapor phases in a mixture of water and acetic acid, both of which are volatile substances. High school students can easily determine the composition of the liquid phase and its corresponding vapor phase at equilibrium using a simple and conceptually…

The aim of this study is to define epigenetic literacy and describe how it can be included in school biology. Epigenetics is a new field of research in biology with abundant societal consequences and conceptual implications on how genetics is understood. Epigenetics explains how genes are regulated, thereby clarifying cell differentiation, and…

This study focuses on undergraduates' preparation for college level courses. In recent international PISA results United States students fall behind seventeen countries on the computer-based reading proficiency test. They have scored low for over a decade, in spite of spending more than one hundred-thousand dollars per student on education. This…
