This article describes the implementation of an activity with a Predict-Observe-Explain (POE) learning cycle to teach the concepts of velocity and acceleration to physics students aged 17-19. The study indicates how the instructor enacted the activity and provides sample student responses and group discussions. The description includes an example…

Although empirical studies have consistently indicated that students commonly struggle to learn and understand the concepts related to reflex actions, few teaching strategies have been developed that specifically address these learning difficulties. This article introduces simple teaching models that simulate the nervous pathways related to the…

As children develop an understanding of their place in the universe, their mental model of the solar system should really go beyond a list of planet names and attributes to become a dynamic concept of bodies in motion and interaction. Montessori educators can help build a Sensorial impression of the cosmos by physically modeling the nature of…

Teachers face challenges when building the concept of substance with students because tensions of meanings emerge from students' daily life and canonical ideas developed in classrooms. A powerful tool to address learning, pedagogical, and research challenges is the conceptual profile theory. According to this theory, people employ various ways of…

Through analysis of a classroom lesson led by a decorated teacher, we illustrate how instructional practices favor students seeking empirical patterns at the expense of using mechanistic reasoning. In the lesson, when students spontaneously come up with hypothetical mechanisms to explain why a light bulb in an electric circuit does or does not…

This study aimed at investigating the effectiveness of using Radioactivity Remote Laboratory Activities (RRLAs) in enhancing Form Four (equivalent to Grade 10) students' understanding of radioactivity and motivation to learn science. For this purpose, in this study, a repeated measures one-way ANOVA design was utilized in which 54 Form Four…

The definition of biodiversity stated by the Convention on Biological Diversity (CBD) in 1992 was conceived as occurring on three different organizational levels: genetic, species, and ecosystems. However, current understanding of biodiversity includes other components, such as the number, abundance, composition, and spatial distribution of…

The Hofmeister series is a recurring trend that ranks ions' abilities to influence various aqueous processes in solution. Herein, a set of project-based experiments was developed for students in an upper-level physical chemistry laboratory to investigate the specific ion effects on the thermodynamics of caffeine partitioning between aqueous and…

Geometry is one of the topics that students must comprehend in mathematics. However, in reality, the students' ability concerning geometry is relatively low due to their low spatial reasoning ability. The ELPSA framework is one of the solutions to develop students' spatial reasoning abilities. This study aimed to describe students' spatial…

This research is motivated by the importance of mathematical reasoning abilities for primary school students. This research aims at looking at the effect of the Concrete-Pictorial-Abstract (CPA) approach on the enhancement of mathematical reasoning abilities of primary school students. This research method is a quasi-experiment with pre-test and…

Marsh et al.'s tests of appropriate spatial relationship concepts were administered to groups of college students to determine whether learning GIS enhances students' overall ability to generate and recognize fundamental spatial relationship concepts. 119 undergraduate students enrolled in various GIS courses and in non-GIS courses participated in…

Background: Educational robotics (ER) is increasingly used in classrooms to implement activities aimed at fostering the development of students' computational thinking (CT) skills. Though previous works have proposed different models and frameworks to describe the underlying concepts of CT, very few have discussed how ER activities should be…

We conducted a study with introductory and upper-division level physics students in a Mexican and a Spanish university to learn how students recognize the main characteristics of the electric field in three of its more widely used representations, namely, algebraic notation, vector field plot, and electric field lines, and how the students do…

In Spain, curricular guidelines as well as the university-entrance tests for social-science high-school students (17-18 years old) include sampling distributions. To analyse the understanding of this concept we investigated a sample of 234 students. We administered a questionnaire to them and ask half for justifications of their answers. The…

Much like one's experiences with the wonders of the world, concrete and multiperspective representations of mathematical concepts are key to understanding. Ideally, "learning environments should give students the opportunity to get to know different representations of a mathematical object in order for them to develop an appropriate…
