Recursion is one of the most difficult programming topics for students. In this paper, an instructional method is proposed to enhance students' understanding of recursion tracing. The proposal is based on the use of rules to translate linear recursion algorithms into equivalent, iterative ones. The paper has two main contributions: the…

Interactive alignment is a phenomenon whereby interlocutors adopt and re-use each other's language patterns in the course of authentic interaction. According to the interactive alignment model, originally proposed by Pickering & Garrod (2004), this linguistic coordination is one way in which interlocutors achieve understanding in dialogue,…

In a course on chemical applications of symmetry and group theory, students learn to use several useful tools (like character tables, projection operators, and correlation tables), but in the process of learning the mathematical details, they often miss the conceptual big picture about "why" and "how" symmetry leads to the…

The relationships between teacher and students are interdependent and rely on their mutual interaction. In the classroom, teaching involves daily face-to-face encounters between students and teachers and therefore could be considered a moral as well as an academic issue. A central question is how the teacher can establish and support a learning…

Using the simplest possible quantum system--the qubit--the fundamental concepts of quantum physics can be introduced. This highlights the common features of many different physical systems, and provides a unifying framework when teaching quantum physics at the high school or introductory level. In a previous "TPT" article and in a…

For millions of gamers and students alike, city building games (CBGs) like SimCity and the more recent Cities: Skylines present a compelling initial introduction to the world of urban planning and development. As such, these games have great potential to shape players' understanding and expectations of real urban patterns and processes. In this…

Much research has shown that a science teacher's beliefs are related to their teaching practice. This line of research has often defined "belief" epistemologically. That is, beliefs are often defined relative to other mental constructs, such as knowledge, dispositions, or attitudes. Left unspecified is the role beliefs play in cognition…

In the nonmajor science classroom, case studies--when used as learning tools--should help students build the necessary framework to understand the nature of science. For most students, the nonmajor science course (in this case, Astronomy 101) may be the last time that they interact with science in a formal learning setting. A National Science…

Collaborative problem solving (CPS) is a critical competency in a variety of contexts, including the workplace, school, and home. However, only recently have assessment and curriculum reformers begun to focus to a greater extent on the acquisition and development of CPS skill. One of the major challenges in psychometric modeling of CPS is…

A characterization of the modelling process in science is proposed for science education, based on Mario Bunge's ideas about the construction of models in science. Galileo's "Dialogues" are analysed as a potentially fruitful starting point to implement strategies aimed at modelling in the classroom in the light of that proposal. It is…

This is an analysis of how specialist music teachers sing and teach how to sing, based on data collected from six case studies carried out in Spanish primary schools. The study aimed at understanding classroom singing practices, and in particular the provision or absence of vocal instruction in relation with teachers' singing models. The findings…

This study was designed to investigate the Effect of Polya Problem-Solving Model on Senior School Students' Performance in Current Electricity. It was a quasi experimental study of non- randomized, non equivalent pre-test post-test control group design. Three research questions were answered and corresponding three research hypotheses were tested…

The paper draws on a series of Australian Research Council (ARC) projects aimed at understanding better the process of doctoral examination. The early phase focussed on the Australian doctorate, which functions without a Viva, while the later phase was concerned with comparing the earlier findings with analysis of the United Kingdom (UK) and New…

One of the requirements of building a learning city is working to ensure its sustainable development. In 2014, UNESCO developed a framework of the key features of learning cities, at the centre of which there are six pillars or "building blocks" which support sustainable development. This article focuses on the third of these pillars,…

Without the study of culture, second language acquisition is not complete (Kramsch, 1993). Teaching about culture raises the learners' awareness of the target culture and compares it with the home culture, providing an intercultural competence (Ibid). Due to the growing number of immigrants in Ireland (CSO Ireland, 2017), there is also an…
