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…

A key part of the practice of chemistry is the analysis of chemical composition, including through gravimetric analysis and spectrophotometry. However, the complexity of doing multiple calculations to obtain analytical evidence, such as that required to determine an empirical formula, presents a challenge if such analytical methods are to be…

Intellectual demands of learning outcomes in the intended curriculum have always been a concern across the field of science education. In particular, the representation of those learning outcomes stipulated by the intended curriculum in science textbooks has become a big issue for both science curriculum studies and science teaching practice. To…

This research will analyze the issues encountered by two science teachers implementing Arduino-based robotic coding projects. This research employed a case study design. This research has used a criterion sampling group. This study used semi-structured observation, interviews, and video observations as data collection tools. The teachers conducted…

Computational and atmospheric chemistry are two important branches of contemporary chemistry. With the present topical nature of climate change and global warming, it is more crucial than ever that students are aware of and exposed to atmospheric chemistry, with an emphasis on how modeling may aid in understanding how atmospherically relevant…

Course-based undergraduate research experiences (CUREs) are being increasingly implemented to broaden the opportunities for undergraduate students to engage in authentic research across STEM disciplines including chemistry. The present review synthesizes the literature on chemistry CUREs, encompassing 68 articles published between 2016 and 2022…

This paper aimed to examine the changes in the representations of nature of science (NOS) in Chinese senior high school chemistry textbooks under the influence of the new curriculum ideas. The study was conducted based on an analytical framework in which the aspects of NOS, the approaches to address NOS, and the content relation of NOS aspects…

Developing students' understanding of the nature of science (NOS) is seen as critical for educating scientifically literate citizens, and has emerged as an important curricular goal internationally. In Norway, a new curriculum reform has recently been implemented, intended to improve the Norwegian education in several ways. The reform aims to…

An undergraduate-level Computational Chemistry project was incorporated initially into a Physical Chemistry course and then into the laboratory curriculum in the subsequent application. Before the introduction of the project, the lectures covered quantum chemistry, spectroscopy, and kinetics while simultaneously including computational chemistry…

It is generally accepted that if a course or curricular transformation is to be implemented with fidelity, the users must understand how and why the transformation is different from their current practices and which aspects of the transformation are essential to achieving comparable student learning outcomes. In this article, we provide a detailed…

Level 3 characteristics are increasingly important for fingerprint identification, particularly when the fingerprints are problematic and lack level 2 details. In practice, no reliable visualization methods for level 3 features are transferred into a course for the general public, forensic students, or investigators. Our group has reported the…

Professional development courses help teachers integrate new content knowledge into the high-school curriculum. Designing practical online courses for this purpose is challenging, particularly in emerging fields such as nanotechnology. In this study, we evaluated such a course in three complementary dimensions: (1) knowledge, (2) the complexity of…

The redesign of the first year basic chemistry course is described at the Rotterdam University of Applied Sciences Chemical Engineer educational course. This was done with the aim to reduce student drop-out during the first year of the educational program. On one hand, it was chosen to teach the basic chemistry course in the laboratory where…

This paper describes the design, implementation, and evaluation of an inquiry-based laboratory for sophomore-level organic chemistry into a mostly cookbook, existing laboratory curriculum. For the laboratory, students were required to generate their own procedures and use their own recorded data from prior laboratory assignments to identify an…

This study aimed to uncover common difficulties and possible areas for improvement by focusing on the approaches and errors made by 3rd-year undergraduate chemistry students in solving organic synthesis problems. The study employed a purposive sampling technique to select 112 undergraduate chemistry major students to participate in this study.…
