This study aims to develop a structured scaffolding-guided inquiry (SSGI) learning model that is oriented toward nurturing argumentation skills to solve complex problems. Test the effectiveness of the SSGI model in improving students' argumentation skills to solve complex problems. This research is development research that refers to Dick and…

It is seen that many opportunities are offered to both students and teachers thanks to the integration of technology into teaching environments. It can be thought that using instructional technologies in the teaching process can enable students to be active in this process, make learning enjoyable, concretize the information, and thus ensure that…

Taking on an agentic perspective, this study employed a digital ethnographic approach to examine a science teacher's emotional experiences in an online graduate science education course during the COVID-19 pandemic. Veronika, the teacher, revealed her feelings of grievance and loss to the graduate course cohort at the advent of large-scale school…

We present our work on a hybridized undergraduate research model that blends the apprenticeship model with that of a course-based undergraduate research experience (CURE) to produce the course apprenticeship-based model (CAB). The purpose of CAB was to incentivize students' interest in undergraduate research at an urban associate granting…

Climate change has the potential to push humans across the limits at which we can exist. Chemistry is essential in understanding the complexities of climate change, as many of the processes involve chemical relationships. Textbooks influence the development of course curricula and support instructors' decision making, which can impact student…

This paper describes an interdisciplinary collaboration of faculty and students from chemistry and mathematics to develop and implement an activity showcasing the relevance of calculus in chemistry to first-semester calculus students. The activity focuses on using calculus optimization methods to maximize the ground-state radial probability…

Titration is an important experimental skill that every chemistry educator and learner must master. Titration is often the method of choice in the science laboratory courses in secondary and postsecondary schools. During acid-base titration, chemistry learners are always told about salt formation. However, a practical visualization of the salt…

A collection of four activities for science outreach events was developed to teach middle school students about the temperature dependence of scientific phenomena. Procedures are described for four interactive demonstrations on phase changes, fluorescence, viscosity effects on diffusion, and conductivity. Each hands-on activity helps students…

Argumentation plays a central role in the development and justification of scientific knowledge. Learners could attain a more scientifically acceptable conceptual understanding by attending argumentation-based discussions. During argumentation-based discussions, students need to activate some metacognitive processes related to concept learning,…

During COVID-19 remote instruction, instructors were tasked with providing students with authentic laboratory experiences in an out-of-classroom environment. One solution developed for our introductory general chemistry laboratory involved students critiquing readily available technique videos to distinguish between correct and incorrect…

This research aimed to examine the impact of argumentation-based chemistry instruction on the argumentation self-efficacy of pre-service teachers' (PSTs') and their perceptions regarding the effectiveness of this instruction on their argumentation self-efficacy. This exploratory study involved a cohort of PSTs who actively participated in a series…

This mixed methods study explored how elementary teachers reported using a commercially published instructional unit to plan and deliver science instruction in their elementary classrooms. Of particular focus is what elements of the program teachers eliminated during planning and instruction, what outside materials teachers added to instruction,…

The field of geometrical optics features a broad knowledge base concerning conceptual learning difficulties and student conceptions. However, in contrast to other areas of physics, no widely used standard test instrument exists to assess middle school students' conceptual knowledge of geometrical optics. This is even more true for other areas of…

This study used a cluster randomized controlled trial to investigate the effectiveness of two approaches to increasing middle school students' science learning when using an inquiry-based science curriculum. Eighty-nine schools, with 253 teachers and 20,591 students, were randomly assigned into one of three conditions: (a) a treatment condition in…

In the context of academic and professional training, effectively constructing arguments is a fundamental skill for chemists. In this way, educational practices that promote this skill are a constant target of attention, as is the analysis of the quality of arguments produced by students. Models capable of supporting this analysis gain importance,…
