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…

Reformed science curricula provide opportunities for students to engage with authentic science practices. However, teacher implementation of such curricula requires teachers to consider their role in the classroom, including realigning instructional decisions with the epistemic aims of science. Guiding newcomers in science can take place in…

Curriculum reform worldwide has often reflected changing perspectives on the teaching and learning of science. Such perspectives underline the notion that not only the teaching of science content knowledge is relevant but also the aims and methods scientists use to further their knowledge and the social context in which science is applied. We call…

This study validated an instrument for measuring student engagement in the context of Chinese science curriculum reforms. We adapted existing items from well-designed instruments with the context of science learning and formed the initial instrument of the Student Engagement in Science Learning (SESL) consisting of 20 items in four subscales,…

Understanding randomness is essential for modern life, as it underpins decisions under uncertainty. It is also an essential part of both the mathematics and science curricula in schools. Yet, research has shown that many people consider randomness difficult to perceive and argue about, with a number of different and contradictory views on the…

As the 21st century progresses, we are increasingly reminded of the importance of and need for green chemistry, which also leads to the corresponding need for green chemistry education. The UC Berkeley Department of Chemistry developed a green chemistry laboratory curriculum-the "General Chemistry Green Curriculum" ("GC[superscript…

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 research reports on implementing the integrated laboratory work to achieve effective learning in the biochemistry course. The integrated laboratory work includes three stages: pre-laboratory, lab work, and post-laboratory. In other words, the three stages include planning, implementing, and evaluating investigation activities in the…

There is growing recognition in the education community that the problem-solving practices that comprise computational thinking (CT) are a fundamental component of both life and work in the twenty-first century. Historically, opportunities to learn CT have been confined to computer science (CS) and elective courses that lack racial, ethnic, and…

Background: Teaching and learning of nature of science (NOS) is an explicit goal in the core science curriculum in Norway. Yet there is little understanding of how the content of the current textbooks in certain educational pathways such as vocational training addresses NOS. Purpose: The aim of this study is to contribute to research on NOS in VET…

This study examines the role of Namibian secondary school science, technology, engineering and mathematics (STEM) teachers' interest in STEM education and self-efficacy in implementing STEM education in science education curricula. Furthermore, it aimed to distinguish male and female Namibian teachers' interests and self-efficacy regarding STEM…

While innovation commonly stems from the Entrepreneurial Mindset (EM), its integration within chemical engineering curricula has been notably limited. However, a shift is occurring as both private and public initiatives are now directing resources and attention toward equipping students for prosperous careers. This paper delineates the successful…

Climate change (CC) is the most significant global issue facing humanity, yet research addressing the perspectives of the key players influential in developing and implementing school-based CC curricula at a cross-country national level is scarce. This study examined the perceptions of policymakers, teacher professional development providers and…

This review summarizes the corpus of literature discussing the science identity of college students from various racial, ethnic, and cultural backgrounds. The purpose of this review is to understand what experiences afford or impede the development of college students' science identity and what strategies are effective for strengthening their…

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…
