The study determined the problem-solving performance and skills of prospective elementary teachers (PETs) in the Northern Philippines. Specifically, it defined the PETs' level of problem-solving performance in number sense, measurement, geometry, algebra, and probability; significant predictors of their problem-solving performance in terms of sex,…

Ontology and epistemology are two different basic disciplines of philosophy. In the course of philosophy history, the priority given to these two different disciplines varied between antique age and middle age and modern era. For sure, this central change was realized in the basis of the connection made by philosophers with metaphysics. The change…

The article analyzes the main problems and contradictions in the formation of legal regimes for the regulation of robotics, artificial intelligence and other innovative technologies of our time. The work content shows the unpreparedness of modern legal science and practice to conceptual and legal design, legal and technical development of the…

A simple forward approach for solving linear Diophantine equations is presented, which does not involve using backward substitutions. It is suitable for teaching undergraduate students as an alternative to the backward substitution method commonly described in mathematics textbooks.

Conversational fluency is important to form meaningful connections and relationships with the people around us but is understudied in children who are deaf or hard of hearing (D/HH). Communication breakdowns reduce conversational fluency. They occur when a speaker says something that interrupts the flow of conversation requiring a request for…

The ability of analysing and designing an algorithm is quite essential for computer science education. The students in the Analysis and Design of Algorithms (ADA) course are expected to be able to solve problems by choosing one of the proper design methods and to analyse the algorithm's performance in terms of various aspects. Instead of using…

This article addresses major lacunae in higher education from the standpoint of Anthropocenic survival. "Wicked problems" transcend national, cultural and disciplinary boundaries. Eco-survival, international migration, destabilized global markets, shifts in the balance of strategic power, population pressures, cultural imperialism,…

Mathematical models that are constructed through modeling activities should be appropriate for the situation at hand. In this study, we seek to monitor the modeling routes of different learners as well as their modeling sub-competencies in order to learn how these are related to the semiotic characteristics of the resulting mathematical models.…

This study examined the effects of presession attention on the acquisition of tacts (Experiment 1) and intraverbals (Experiment 2) in children diagnosed with autism. Each participant experienced 3 conditions. In the first 2 conditions, participants experienced a 15-min interval of either presession attention (PA) or no presession attention (NPA)…

Studies on the productive failure (PF) approach have demonstrated that attempting to solve a problem prepares students more effectively for later instruction compared to observing failed problem-solving attempts prior to instruction. However, the examples of failure used in these studies did not display the problem-solving-and-failing…

Much of the education research on implicit differentiation and related rates treats the topic of differentiating equations as an unproblematic application of the chain rule. This paper instead problematizes the legitimacy of this procedure. It develops a conceptual analysis aimed at exploring how a student might come to understand when and why one…

While research that is embedded in schools is reported widely in education and psychological research literature, studies that focus on how researchers might navigate school-based gatekeepers is minimal. This study addresses this gap. The research presented in this paper reports on the recruitment process that was employed in a study that involved…

A well known physics problem is to calculate the friction forces required to support a ladder against a wall. A more tractable problem is to calculate the friction forces needed to support an inclined beam on a ball or a cylinder. In the latter case there are three rather than two points of sliding support. Measurements and calculations are…

Recently, Lima lamented on the 'time-consuming and tiresome' pedagogical nature of repeated integration by parts, throwing down the challenge of providing a pencil-and-paper solution to a related problem in a few seconds. Lima put forth a simple formula as an alternative. In this work, I offer a response to Lima's challenge and his formula.…

In many discussions of the ways in which abstraction is applied in computer science (CS), researchers and advocates of CS education argue that CS students should be taught to consciously and explicitly move among levels of abstraction (Armoni "Journal of Computers in Mathematics and Science Teaching," 32(3), 265-284, 2013; Kramer…
