This paper reports on an exploration of preservice teachers' understanding of the quadratic function concept in Zimbabwe. These concepts were taught to preservice teachers studying for a diploma in Education wishing to specialize in the teaching of Ordinary level mathematics. Concerns about high Mathematics failure rate in Zimbabwean Secondary…

This article uses action-process-object-schema theory to study the mental constructions about the limit of series during a Calculus 1 course at a university. The researchers also used the theory's teaching methodology to teach the topic. A plethora of research on the limit concept is available and suggests that the concept is on record as being…

The literature highlights differing views on the efficacy of modelling lessons for teacher professional learning. In this study we draw on dissonance theory to discuss lesson modelling that seeks to transcend 'do as I do' imitation and provoke teachers' attention to intended teaching practices: a necessary pre-cursor for changes to practice. A…

This is a conceptual paper based on existing literature aiming to provide practical information on designing and implementing activities to promote children's computational thinking. Computational thinking is a relatively new term in early childhood education that refers to a specific problem-solving thinking process involving various logical and…

Although teachers need to assess computational thinking (CT) for computer science education in K-12, it is not easy for them to evaluate students' programs based on the perspective. The purpose of this study was to investigate students' CT skills reflected in their Scratch programs. The context of the study was a middle school coding club where…

In this study we analysed what computational thinking skills pupils used when programming a small robot to solve a given problem, a simple programming task in which pupils had to select codes and put them in the correct place. Computational thinking is the process of (re)formulating a problem so that it becomes possible to use computer technology…

This study aims to investigate students' computational thinking (CT) through mathematical tasks integrated with programming in Scratch. Participants completed four tasks that required students to solve coding problems, which were focused on prime numbers and the prime factorization algorithm. The study was designed as a case study and the unit of…

Our study documents how a Spanish-English bilingual elementary teacher learned computational thinking while working to incorporate it into mathematics and language arts lessons in a bilingual classroom. We classified the elements of the teacher's process into two practices: intentional and unintentional use of computational thinking. Intentional…

Serious games (SGs) offer an engaging format for teaching industrial engineering (IE) methodologies. IE methodologies involve people following a process in a set of conditions to design, improve and install systems, which are easily scripted into gameplay. The scholarship has proposed co-design approaches for teachers and SG designers. However,…

While child development is well-recognized as a complex process which could hardly be decomposed into separate lines or domains in contemporary psychological theories, the decomposition approach is widely used in empirical studies. Based on the cultural-historical theory, this study argues for adopting the unit of analysis as a way to bridge this…

Describes activities in which students explore composting. Enables students to learn that all organic material returns naturally to the earth through a process of decomposition that involves many living organisms. (JRH)

One of the subjects that undergraduate students learning Object Oriented (OO) design find hard to apply is the construction of class hierarchies in general, and the use of interface classes in particular. The design process requires decomposition and reconstruction of problems in order to model software classes. The common attributes and behaviors…

Literacy requires reading comprehension, and fostering reading skills is an essential prerequisite to and a synergistic enabler of the development of writing skills. Reading comprehension in the chemical sciences not only consists of the understanding of text but also includes the reading and processing of data tables, schemes, and graphs. Thus,…

In order to teach Computational Thinking (CT) skills to young students, Block-Based Programming Environments (BBPEs) are integrated into secondary school computer science (CS) education curricula. As a CT skill, abstraction is one of the prominent skills, which is difficult to enhance and measure. Researchers developed some scales for measuring…

In computer science, students could benefit from exposure to critical programming concepts from multiple perspectives. Peer review is one method to allow students to experience authentic uses of the concepts in an activity that is not itself programming. In this work, we examine how to implement the peer review process in early, object-oriented…
