Here we demonstrate how data from the clinical pulmonary function lab can help students learn about the principle of airway-parenchymal interdependence. We examined the relationship between airway conductance (Gaw) and lung volume (thoracic gas volume, TGV) in 48 patients: 17 healthy; 20 with emphysema, expected to have reduced airway-parenchymal…

This study analyses the effectiveness of directed vs. minimally directed inquiry-based instructional approaches in improving students' attitudes toward physics. It specifically compares the impacts of cognitively guided instructional strategy (CGIS) and Cubing instructional strategy (CIS) on student attitudes. Using a pretest--post-test…

Atomic-level visualizations serve as pivotal instructional tools in chemistry education, providing insights into the particulate level of matter, a dimension fundamental, yet typically invisible, in the study of chemistry. This research investigates how students' engagement with these visualizations influences their conceptual understanding of…

Since the 2000s, the Joint Action framework in Didactics (JAD) has been developed in the context of the expansion of the French-speaking research in Comparative didactics. Studies carried out with this framework typically investigate how knowledge content develop in teacher-student classroom interactions. From a quite different perspective,…

A comparison of student performance in an introductory biology class that used a lecture-based approach (N = 15 classes; 462 students) with those that had a no-lecture approach (N = 9 classes; 238 students). All classes were taught by the principal researcher. In the no- lecture environment, shifts in student perceptions of science were…

Video instruction has been widely studied and is generally considered as effective as live instruction for teaching scientific concepts and procedures. However, there is limited research on the effectiveness of prerecorded videos for teaching more challenging content. This study conducted a controlled experiment on over 300 high school students to…

Developing students' scientific literacy is the most important educational goal and challenge of the 21st century. Many studies have confirmed that flipped learning has significantly impacted learning science. Researchers indicate that the lack of an appropriate learning guidance strategy in the pre-class stage for flipped learning will influence…

This article reports on the effect of textbook analysis as a tool of teacher professional development on nature of science (NOS) understanding of 10 science teachers in South Africa. The teacher professional development program (TPDP) was based on an explicit reflective methodology of textbook analysis and conducted online due to the Covid-induced…

The low level of students' scientific reasoning skills is caused by the low-quality learning process. Action is needed to improve the learning process by applying innovative learning models, the Reading, Identification, Constructing, Solving, Reviewing, and Extending (RICOSRE) learning model. This research aims to determine the effect of RICOSRE…

The preparation gap [Salehi et al., Phys. Rev. Phys. Educ. Res. 15, 020114 (2019)] refers to gaps in students' prior knowledge that can negatively affect their learning as they engage in introductory physics courses. To better characterize the gap, the current study distinguished the impact of various prior knowledge components on learning gains.…

Despite increased research interest in improving students' scientific inquiry abilities, how to conduct scientific inquiry using science textbooks that are easily accessible to primary school students remains understudied. This study developed and verified an inquiry activity model (IAM) to improve the performance of primary school students in…

As science educators seek innovative methods to engage students, the Culturo-Techno-Contextual Approach (CTCA) has emerged as a promising strategy, particularly for African students. CTCA is a culturally responsive teaching method that integrates culture, technology, and locational context, making science more relatable and meaningful. We assessed…

This study explored the effects of a novel intervention, binaural beats (BB), on anxiety levels of anatomy students during cadaveric dissections and its impact on the learning environment. The study was quasi-experimental, employing a purposive sampling strategy. State (SA) and trait (TA) anxiety levels were measured using the State-Trait Anxiety…

We investigate students' eye movements when they solve sequential and simultaneous synthesis physics problems. In sequential synthesis problems, multiple events occur chronologically, whereas in simultaneous synthesis problems, multiple events take place concurrently. We captured students' eye fixations on each problem diagram and recorded their…

The low scientific literacy in students is due to several factors such as lack of motivation, negative attitudes towards teachers, low self-esteem, and lack of confidence in self-ability. This study aims to analyze the effectiveness of the Numbered Head Together (NHT) learning model based on the Growth Mindset of scientific literacy and learning…
