This study thoroughly explores the relationships between the challenges faced by students and the alternative problem-solving strategies employed. By analyzing these connections, the research aims to offer a comprehensive understanding of how students address difficulties in science learning and the adaptive strategies they apply. Through this…

DBL is a novel pedagogical approach intended to improve students' conditional knowledge and problem-solving skills by exposing them to a sequence of branching learning decisions. The DBL software provided students with ample opportunities to engage in the expert decision-making processes involved in complex problem-solving and to receive…

Every three years, the Organisation for European Cooperation and Development evaluates the scientific competence of European students. Recent results have demonstrated that scientific competence in Spain is somewhat underdeveloped, which underscores the need to apply educational methodologies that favour the development of said competence. This…

This research analyzed the state of metacognition in South African Physical Science classrooms, the extent to which South African Physical Science teachers possess metacognitive awareness, and how effective the teachers are in fostering metacognition. Assessment of the current state of metacognition in a sample of Physical Science classes at two…

Plant extracts and their components have been reported to have antimicrobial properties against phytopathogens. Although such properties could be harnessed for the development of new pathogen control strategies, there are no standardised methods for their assessment in different extracts. The laboratory exercise presented here involves the use of…

The urea cycle disorder drug glycerol phenylbutyrate (Ravicti) is presently one of the most expensive medications in the United States, with annual costs estimated at $800,000 as of 2023. An expedient synthesis of this orphan drug was successfully adapted for the undergraduate organic chemistry laboratory. Activation of 4-phenylbutyric acid with…

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…

Concepts and practices surrounding measurement uncertainty are vital knowledge for physicists and are often emphasized in undergraduate physics laboratory courses. We have previously developed a research-based assessment instrument--the Survey of Physics Reasoning on Uncertainty Concepts in Experiments (SPRUCE)--to examine student proficiency with…

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…

In response to the shifting modalities of laboratory-based education, particularly amidst the rise of virtual and at-home instruction, we introduce a novel hybrid laboratory module for undergraduate biochemistry and biology courses. Central to this innovative approach is the use of sourdough as a versatile and accessible model organism, enabling a…

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…

The flue gas from waste incineration power plants contains high-level zinc species that may deactivate the catalyst for selective catalytic reduction (SCR) of nitrogen oxides (NO[subscript x]) with NH[subscript 3]. A comparison experiment was designed to investigate the effect of different types and Zn/Ce molar ratios on the performance of…

Einstein's derivation of special relativity theory (SRT), based on hypothetical reasoning and thought experiments, is regarded as a prime example of physics theory development. In secondary education, the introduction of SRT could provide a great opportunity for students to engage in physics theorizing, but this opportunity is largely being missed…

The study examined the effectiveness of concept mapping in improving students' academic performance using an embedded mixed-methods design. It involved Srinka Secondary School's grade 10 biology teacher, students, and department head in the study and gathered data from them by using biology achievement tests, interviews, and focus group…

This study aimed to: 1) assess the impact of a STEAM education learning package on grade 10 students' science process skills, 2) evaluate its effect on their learning achievement concerning the physical properties of materials, and 3) gauge the students' satisfaction with the learning package. The participants were 13 grade 10 students from a…
