Background Improving scientific reasoning and argumentation are central aims of science education. Because of their complex nature, self-regulation is important for successful scientific reasoning. This study provides a first attempt to investigate how scientific reasoning and self-regulation processes conjointly impact argumentation quality.…

We developed and field-tested an active learning exercise designed to provide biology students with the opportunity to consider key aspects of the nature of science as a method of inquiry, particularly the roles of observation and inference in the development of scientific explanations and how scientists deal with uncertainty. In the activity…

Abstract Microbiome study requires both molecular techniques and bioinformatics skills, which are challenging for biologists to participate in this growing field. To introduce microbiome concepts and skills to students, a 6-week wet-lab and bioinformatics course for undergraduates was implemented through the project-based learning (PBL) approach.…

Understanding scientific phenomena requires learners to construct mental models of causal systems. Simulation-based discovery learning offers learners the opportunity to construct mental models and test them against the behavior of a simulation. The purpose of this study was to investigate sequential patterns of learner actions and utterances…

In this study, we developed machine learning algorithms to automatically score students' written arguments and then applied the cognitive diagnostic modeling (CDM) approach to examine students' cognitive patterns of scientific argumentation. We abstracted three types of skills (i.e., attributes) critical for successful argumentation practice:…

Background: STEM education and research are increasingly emphasized by governments worldwide to foster national development and productivity, economic competitiveness and societal wellbeing. There is no exception in Hong Kong, with its desire to promote STEM education and to strengthen Innovation and Technology development in the future. Purpose:…

Uncertainty is endemic to scientific research practices; therefore, it is also an important element in learning about science. Studies have shown that experiences and management of uncertainty regarding the epistemic practices of science can support learning. Whereas the common strategies of supporting students in handling uncertainty rely on the…

A laboratory experiment was developed for the continuous flow preparation of an aminal derived from the condensation of furfural with morpholine. The experiment introduces the students to concepts of green chemistry, heterogeneous catalysis, and continuous flow. A cheap and easy setup allows the heterogeneous catalyst reactor to be built in class.…

The independent curriculum is designed to be a better future solution for education in Indonesia. This curriculum is expected to reduce the learning losses that occurred after the COVID-19 pandemic. In the independent curriculum at the elementary school level, natural science subjects are changed to natural and social science subjects. Natural…

Modeling an inter-ring torsional profile of a simple2,2'-bithiophenemolecule has been used to illustrate the main concepts associated with basic molecular modeling within an introductory course in a master's degree on computational modeling. The methodology proposed in the activity has been used to guide and train the student along the classical…

The teaching of laboratory skills to undergraduate students is central to all experimental sciences. In this setting, students must understand the experimental procedures as well as the fundamental principle(s) being demonstrated, all while learning within a limited time. Other limiting factors include access to equipment and reagents, resulting…

In the sciences, energy is an important idea to get insight into phenomena, as energy can help to reveal hidden systems and processes. However, students commonly struggle to use energy ideas to interpret and explain phenomena. To support students in using energy ideas to interpret and explain phenomena, a range of different graphical…

Experiment is understood as a core activity in science education as well as science in general. Despite many efforts to improve science education in the laboratory, a cookbook style of verification experiments often dominate school science. In this study, we conducted an open laboratory activity that provided students with an opportunity to think…

Each year, an increasing number of science teachers integrate modeling into their instructional repertoires, and in the process, they see how this disciplinary practice helps students reason and revise their thinking about complex events in the natural world. The NGSS Science and Engineering Practice of developing and using models is intended to…

As students learn physics, they are often required to reason about the behavior of macroscopic and microscopic phenomena, and to synthesize prior knowledge from several different areas of physics to construct understanding of new ideas. This can be a tremendously difficult cognitive task for novice students, especially when the unfamiliar…
