Some students could not learn organic chemistry because of the difficulty of its submicroscopic nature. In this study, it was aimed to determine the effect of argumentation-based organic chemistry teaching on high school students' argument construction skills so on their meaningful concept learning. The study was conducted on 14 high school…

Student-centered teaching has become increasingly common in higher education as researchers have demonstrated its efficacy in recent decades. Herein, we hope to establish an efficient problem-based learning (PBL) method, which can help upper-division students learn organic chemistry content by combining teaching materials, experimental literature,…

There is an assumption that graduate teaching assistants (GTAs) have mastery of the chemistry content they are teaching and preparation to instruct students. However, in reformed classrooms, GTAs may need more support and resources. We designed chemistry rehearsal modules for use in a mixed-reality teaching simulator to help prepare GTAs for…

Techniques from the branch of artificial intelligence known as machine learning (ML) have been applied to a wide range of problems in chemistry. Nonetheless, there are very few examples of pedagogical activities to introduce ML to chemistry students in the chemistry education literature. Here we report a computational activity that introduces…

An experiment in teaching students to use the literature to devise and defend a plan for novel research is presented as part of a graduate-level course in heterocyclic chemistry. Students in three successive iterations of the course completed an assignment during which they were assigned novel heterocyclic cores that were selected by varying or…

Interest within the chemistry education community in incorporating sustainability into chemistry education has converged on a systems thinking approach, and efforts to implement this are ongoing. One challenge to implementation is the different amenability to systems thinking approaches of topics that are important in chemistry at the…

Adaptive learning is an educational method that uses computer algorithms and artificial intelligence (AI) to customize learning materials and activities based on each user's model. Adaptive learning has been used for more than 20 years. However, it is still unique, and no other system could bring more or even similar capabilities than the ones…

The forced move to online learning in the arrival and persistence of the COVID-19 pandemic underscored the present lack of models for fully online general chemistry laboratory courses. While there exist a fair number of simulation platforms, video libraries, and one-off virtual experiments, a lack of complete general chemistry lab online courses…

Acid-base titration laboratories are perennially offered to general chemistry students in preparation for summative assessments of their hands-on and quantitative skills in the field. Here, we present a guided inquiry-based activity focused on total titratable acidity (TTA) as alternative to standard "cookbook" titration laboratory work.…

The main aim of this study was to investigate the effect of inquiry-based laboratory instruction on ninth grade students' scientific inquiry views. In this study an argument driven inquiry approach to laboratory instruction was used to teach a Chemistry lesson where the nature of the aspects of scientific inquiry was explicitly taught. This…

An instructional approach is presented for teaching the mole concept to high school introductory-level chemistry classes. Extensions to the strategy are presented for more advanced classes. The strength of the approach is based upon discovery. Students discover the Avogadro number and the mole concept. The discovery is based upon calculations that…

At the core of an effective model-based inquiry (MBI) unit is a scientifically rich, complex phenomenon that serves as the reason for engagement and drives student sensemaking and investigations throughout the unit. Engaging in iterative attempts to explain phenomena over the course of an MBI unit allows the opportunity for students to construct…

This study aims to develop and validate a new instrument for measuring chemistry teachers' perceptions of Pedagogical Content Knowledge for teaching Chemistry Core Competencies (PCK_CCC) in the context of new Chinese chemistry curriculum reform. The five constructs and the initial 17 items in the new instrument were contextualized by the PCK…

Chemistry is essential to individual and societal well-being, yet publics tend to express less interest in chemistry compared to other science fields, and many scholars have highlighted the need for more research on effective chemistry communication and informal learning outcomes. Here, we describe one strand of a collaborative, multiyear study,…

How do different components of a learning environment contribute to learning in science? The study examines the contribution of laboratory experiments and computer model explorations to the learning of chemistry through a complex-systems approach. Specifically, junior high-school students' learning of chemistry via four different methods were…
