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.…

[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…

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,…

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 paper presents a methodological approach based on the use of complex networks to analyze the structure and content of curricula. We analyze the concept network built from the final year of a particular high school physics curriculum, as well as that of mathematics. We examine the most central nodes in each case, the community structures…

The teaching and learning of chemistry can be challenging due to the complex and abstract nature of the subject matter. Traditional methods of instruction often struggle to engage students and facilitate an understanding of essential chemical concepts. To address this, an innovative card game, "Compound Chain", was developed and…

This paper re-validates middle school students' learning progression of the concept of buoyancy (Gao et al., 2020) by using two-time point data. The previous study developed a four-level learning progression based on data collected at a single time point using cross-sectional design. This single-time-point model of learning progression calls for a…

This action research case study explored the ability of three high school chemistry students to grow in their understanding of nature of science (NOS) during its explicit-reflective inclusion in two unit chapters on bonding (ionic compounds followed by covalent molecules). Students completed a pre, post and delayed Views of Nature of Science Form…

One reason for the widespread use of the energy concept across the sciences is that energy analysis can be used to interpret the behavior of systems even if one does not know the particular mechanisms that underlie the observed behavior. By providing an approach to interpreting unfamiliar phenomena, energy provides a lens on phenomena that can set…

The aim with this study was to analyse and explore how physical sciences, engineering science and technology subjects (technical electrical technology, technical civil technology, technical mechanical technology) can contribute to the alignment of the technical sciences curriculum. We used document analysis to collect data. An analysis of the…
