This is a qualitative case study framed by a sociosemiotic theoretical framework to explore science and language instruction with three Emergent Bilinguals (EBs) in sixth grade. The study details the modeling and explanatory processes used by EBs to mediate science learning through evidence-based argumentation. A thematic analysis of students'…

The 21st-century mathematics classrooms should equip learners with well-grounded knowledge and thinking skills pertaining to geometry. However, Euclidean geometry remains one of the challenging, if not the most difficult topic for many learners. As a result, the purpose of this article is to interpret Grade 12 learners' learning difficulties in…

This study examined the effect of a professional development training programme on 20 second-year preservice mathematics teachers' knowledge in foundational mathematical concepts at a rural university in South Africa. The training programme aimed to enhance preservice teachers' mathematical knowledge for teaching. An embedded mixed-methods case…

Equivalence is a concept that comes up across the entire K-12 grade span and in many different areas of mathematics. Students who are bureaucratically designated as "English Learners" can explore equivalence across their K-12 academic careers while developing language to connect ideas. Drawing on what is known generally from theory and…

The topic of keeping livestock is very well suited to addressing the ecological, social, and economic aspects of the sustainable production of our food in school lessons. However, the production of animal-based foods is mainly outside the personal experience of children and young people. To derive relevant implications for teaching, this paper…

Kingdom Plantae is a topic taught in Grade Tenth in Indonesia high school. The previous researchers have found misconceptions and difficulties in understanding the classification and the nomenclature system of Kingdom Plantae. Understanding basic concepts of Kingdom Plantae is important to study the more complex system of Plantae. This research…

Children's concept of biological phenomena differs from scientific thought in many aspects. The revelation of wrong concepts contributes to better education, especially when that information is described in a specific field of science. Not only children, but also adults often use anthropomorphic and theological explanations to express their ideas,…

In recent years, smartphone sensors have been frequently used in educational demonstrations to improve students' understanding of certain physical kinematic topics. In particular, the sensors on modern smartphones enable students to use their phones as physics mini-laboratories, and they have been used to analyze objects' speeds and accelerations…

A "map" is presented to describe the different stereochemical relationships among carbohydrates, in both the hexose and pentose series. When implemented, it allows chemistry students, teachers, and researchers to readily identify different sugars' stereochemical interconnections. It may also help orient chemists toward retrosyntheses, in…

This is a response to two discussions of my article 'The Weakness of "Powerful Knowledge"' featuring in 2018 in the "London Review of Education" 16 (2), the first by Johan Muller and Michael Young and the second by Jim Hordern. It also makes brief comments on pieces on powerful knowledge in the "London Review of…

Children's creative imagination is tested through tasks involving narrative and drawing abilities for participants between the age of 8 and 12 years. The test determines the relative importance of 'narrative' against 'graphic' imagination in interpretive, problem-solving strategies, and also considers how such distinctive functions of the creative…

The efficiency and popularity of computer-aided design (CAD) packages have been continually improving over the past couple of decades. Most of the graduating engineers are proficient in their use and prefer using CAD models instead of simple freehand sketches to communicate their ideas. While these CAD models can enable better visualization of the…

Multiple chemistry education research studies at the secondary level have characterized students' difficulties regarding a conceptual understanding of the quantum model of the atom. This research explores undergraduate students' interpretations of multiple representations of the atom. Semistructured interviews were conducted with first-year…

The creativity of the brain is usually measured by one's creative behavior or activity. This study explores connections between an individual's creative behavior and his or her creative brain by asking each participant to design an open-ended virtual product in an integrated system consisting of virtual reality and brainwaves. The results show a…

Reforms taking place in the educational process of higher professional school impose new requirements on the quality of training students. Today, graduates of higher educational institutions are required to have new professional thinking, high mobility, competence, tolerance and focus on intra-group activities carried out in teams. With the team…
