Paal--Knorr reactions are a classical method for synthesizing pyrroles, using 1,4-dicarbonyl compound and amine as reactants. It has the characteristics of green chemistry, as only two molecules of water are lost. In this teaching and learning experiment, 2,5-hexanedione and 4-"tert"-butylaniline were used to synthesize…

The purpose of this study is to examine how and in what ways the dimensions of the nature of science are included in the 6th, 7th, and 8th grade science textbooks taught between 1926 and 2018 and to determine how these dimensions are represented in textbooks based on curricula shifts. In this study, a total of 24 textbooks allowed by the Ministry…

This study employed a mixed-methods design to investigate the impact of activities developed by the Ministry of National Education (MoNE) on the scientific creativity and scientist perceptions of gifted 5th-grade students. The research used a one-group pretest-posttest design with a sample of 22 students from a Science and Art Education Centre in…

Ojhung is one of the indigenous Indonesian cultures from Sumenep Regency which contains relevant science concepts to be applied in science learning. Therefore, this research aimed to identify and explore the concepts of science contained in the Ojhung tradition while evaluating their relevance to the "Merdeka" or national curriculum.…

Artificial intelligence (AI) is now a major driver of societal acceleration making a significant impact on science and science education. AI is used by scientists to generate hypotheses, design experiments, collect and interpret data in ways that were not previously possible with traditional methods alone. Science education research is…

[This paper is part of the Focused Collection in Investigating and Improving Quantum Education through Research.] Instructors teaching upper-division quantum mechanics have had two primary options when it comes to textbook choice and thus curriculum sequence: starting with wave functions and the Schrödinger equation, referred to as "wave…

We review the literature, from 2006 to 2020, focused on the teaching and learning of chemical bonding. The studies included in our review (48 studies set in 19 different countries overall) involved secondary and postsecondary students as well as K-12 teachers and university faculty. We synthesize these studies' findings to provide implications for…

Chemical bonding is central to explaining many phenomena. Research in chemical education and the Framework for K-12 Science Education (the "Framework") argue for new approaches to learning chemical bonding grounded in (1) using ideas of the balance of electric forces and energy minimization to explain bond formation, (2) using learning…

This study aims to make a thematic classification of possible misconceptions about solid friction by reviewing papers in the literature which include conceptual difficulties about friction; in this way, the study contributes to the literature. The study's scope was limited to the dry friction that occurs with the interaction of two solid objects,…

While scientific vocabulary is important, it can often become problematic for students. Sometimes, those words can become a barrier to participation or act as a gatekeeper to success in the science classroom. Under the Next Generation Science Standards, middle school students are expected to model Earth-Moon-Sun motions to explain Moon phases,…

This document presents the changes belonging to the published article. The study aimed to examine the opinions of the instructors who work at GUHEM (Gökmen Space and Aviation Training Center) on the exhibition's content, how the exhibition spaces contribute to science education, especially astronomy and aviation, and the types of visitors who…

Much research attention has been focused on learning through game playing. However, very little has been focused on student learning through game making, especially in science. Moreover, none of the studies on learning through making games has presented an account of how students engage in the process of game design in real time. The present study…

This study investigated evidence of how students' mental models of fundamental kinematic relations evolved (i.e., developed cognitively over time) as observed during an introductory course in calculus-based classical mechanics. The core of the curriculum is based on a claim known as Galileo's principle of relativity. The course material comprised…

The central pedagogical principle on which the "Next Generation Science Standards" (NGSS) are built is that of three-dimensional learning. This principle posits that it is through meaningful integration of the disciplinary core ideas (DCIs), science and engineering practices (SEPs), and crosscutting concepts (CCCs) that students will…

It is 157 years since Mendel presented his results on hybridisation in peas to the Brünn Society for Natural Science. The discipline of genetics has dramatically changed since then, with technological advancements revealing multifactorial causation and trait variability. Whilst none of this complexity featured in the discovery of classical…
