This study describes students' learning obstacles in solving early algebra problems requiring functional thinking ability. To reach this aim, qualitative research was conducted in this study. Participants of this study were 39 ninth graders and a mathematics teacher at one of the lower secondary schools in Bandung, Indonesia. The data were…

Chemistry topics are ubiquitous in healthcare diagnostics as well as health professions undergraduate curricula. However, there are limited correlations between chemistry and healthcare made in textbooks or template lecture materials. For undergraduate nursing students (BSN) enrolled in a Chemistry for Health Professions course, the author (and…

Enhancing the mathematical problem solving and conceptual understanding of Year 6 students was the goal for a team of primary teachers. For this purpose, they investigated a teaching approach involving Challenging Tasks as a Professional Learning Community. The process followed by the team is outlined, and the impact on teaching and learning is…

In this paper we analyze common solutions that students often produce to isomorphic tasks involving proportional situations. We highlight some key distinctions across the tasks and between the different equations students write within each task to help elaborate the different interpretations of equivalence at play: numerical, transformational, and…

The current study examines the progress of 8th-grade student drawings and written explanations of chemical phenomenon, subsequent to being involved in an instructional strategy that explicitly involves drawing as a supportive toll to construct scientific explanations. Additionally, the study examines the association between the representation of…

In the age of change, rapid changes occur in the education and teaching process as in every field. The changes have brought new insights and practices to the mathematics teaching process, just like any other lesson. One of these changes is teaching with storytelling method. Learning with this method can be envisaged to warrant a more permanent,…

The purpose of the present research is defining the direction and level of the relationship between 8th grade students' translating among multiple representations skills and their algebraic reasoning and revealing the predictive power on algebraic reasoning. The research was conducted in accordance with relational survey model, which is a…

Understanding and constructing domain-specific external representations, such as kinematic diagrams, is an important goal of engineering education. International standards (ISO 3952-1) prescribe their format in terms of graphical elements in black and white and two dimensions. However, during training, the canonical format is often modified under…

Physical education contributes greatly to the physical, psychological and intellectual development of individuals. The awareness of the students of the coaching department about the concept of physical education should basically be revealed. The aim of this study is to reveal the perceptions of students studying in the coaching department about…

Constructing causal mechanistic explanations of observable phenomena is a key science practice that is often challenging for students as most mechanisms involve interactions of unobservable entities and activities. In this study, we examined how gesturing with a computer simulation that depicts the molecular mechanism of thermal conduction…

In this laboratory experiment, the synthesis and characterization of H[subscript 5]PV[subscript 2]Mo[subscript 10]O[subscript 40]@Cu[subscript 3](BTC)[subscript 2] (denoted as NENU[subscript -9], H[subscript 3]BTC = 1,3,5-benzenetricarboxylic acid) and its application in fuel desulfurization were performed. This experiment is designed for advanced…

The bicycle is one of the greatest locomotive machines ever invented. It is also a perfect vehicle for you to teach some of the ideas that are taught in forces topics to 11- to 16-year-olds. In this article we look at some of the ways in which you can use the bicycle and cycling to provide an alternative and engaging context for teaching some of…

A quantitative experiment where we measure the acceleration of spheres of radius "R" rolling on an inclined U-shaped profile of width "2D" is presented. For a given inclination, we examine the behaviour of four solid spheres having different diameters; in contrast to what is usually assumed to be the case, the experimental…

Widely recognized lately, interactional competence (IC) has been of growing research interest. However, there are still some questions and gaps in conceptualizing, operationalization, and assessment. The present article examines the evolution of the combination of concept-based instruction (CBI) elements and conversation analysis (CA) findings…

Problems teaching probability in Tonga (in the South Pacific) led to the question on how language and culture affect the understanding of probability and uncertainty. The research uses a discursive approach to identify the endorsed narratives which underlie Tongans' reasoning in situations of uncertainty. I aim to justify the claim that the Tongan…
