Millions of people do not have access to clean drinking water; thus, cost-efficient water treatment systems are vital. Chemists, environmentalists, technicians, and engineers will be the professionals making breakthroughs in this industry. This laboratory experiment aims to introduce undergraduate students to the removal of pollutants from water…

This paper introduces two theoretical constructs, open-loop covariation and closed-loop covariation, that combine covariational reasoning and causality to characterize the way that three preservice mathematics teachers conceptualize a feedback loop relationship in a mathematical task related to climate change. The study's results suggest that the…

Developing students' mathematical knowledge is the key focus of stakeholders involved in mathematics education. At the senior secondary level, for students' undertaking calculus-focused courses, teachers expect students to be fluent in applying procedures related to junior level content and understand the nature of mathematics as a web of…

Ultrafast laser spectroscopy is a valuable and increasingly accessible technique for studies of rapid chemical reactions. Critical to ultrafast spectroscopy is the concept of mode locking, a technique that enables a fixed phase relationship between laser modes, resulting in laser pulses with very short duration (in the fs or ps range). Despite the…

This research aims to investigate the construction of the area of rectangle with GeoGebra and how students can formulate it. It focuses on describing the cognitive process involved in constructing this concept and how technology mediates such a process. The research was conducted in a classroom with 5th grade students in a secondary school and was…

English Learners benefit from small group sorting activities with clear structures to participate. Early in a lesson, students can sort to surface prior knowledge and develop categories. Later, sorting helps English Learners coordinate and connect multiple representations. As they extend understanding, English Learners can make new connections and…

A research project on using comics for teaching mathematics was initiated in one Singapore primary school. One class of Grade 5 (students of age 11-12) students was exposed to comics for mathematics instruction. This paper reports a case study of seven students' perception of the features of the comics instructional package and how these features…

This article reflects on the author's experience of developing a standalone geographies of sport module that is taught using an active blended learning (ABL) approach. The article argues that an ABL pedagogy is an effective way of teaching meaningful sports geography to undergraduate students. It discusses how the approach allows a diverse range…

Current educational systems are making shifts from teacher-centered to learner-centered environments. This shift creates space for more involvement from students in their own instructional and assessment processes that sets them up for success in a method that allows them control of their achievement. Teachers have to assess and reflect on their…

This study aims to compare the efficacy of simultaneous prompting presented via tablets and visual cards in the instruction of spatial concepts to students with intellectual disabilities. A mobile learning software was developed within portable devices by using simultaneous prompting method to teach spatial concepts. The adapted alternating…

The study examined the effectiveness of BEEP Cards (BioEnergetics Enhancement Play Cards) on students' conceptual understanding of bioenergetics. The study involved one group of grade 11 students (n=29) from a public secondary school in the Philippines. The study employed a mixed-method research design, utilizing both quantitative and qualitative…

Multisensory environments rich in modal integration provide cues from various sensory modalities including visually, auditorily, and tactilely. Such modal integration plays a crucial role in cognitive processing, specifically in fostering creativity. Numerous studies highlight that emotional coherence through cross-modal affective integration…

Purpose: This study aims to explore children's cognitions about data flows online and their understandings of algorithms, often referred to as algorithmic literacy or algorithmic folk theories, in their everyday uses of social media and YouTube. The authors focused on children ages 8 to 11, as these are the ages when most youth acquire their own…

Engineering drawing is valuable in capturing geometric features, conveying engineering ideas, and creating a blueprint of the intended product. Engineering students usually perform orthographic projections, imagining a 3D situation and sketching its 2D representation. That requires imagination and mental visualization, determined by the learner's…

Literature suggests that "current characterizations of the terms procedural knowledge and conceptual knowledge are limiting and are, in fact, impediments to careful investigation of these constructs" (Star, 2005, p. 405). We examined secondary mathematics teachers' understanding of procedural and conceptual knowledge at superficial and…
