There has been a large amount of research about the impact of dynamic geometry software (DGS) on the learning of mathematics mainly related to different representations of mathematical concepts and functional dependences. This paper goes beyond these investigations by suggesting meaningful connection and integration of DGS with physical resources…

Purpose: Traveling Salesman Problem (TSP) that can be extended and modified in various ways, is a practical and realistic type of problem and forms the basis for the visual and spatial solution of many optimization problems. In this study, 15, 25 and 35 nodes Travelling Salesman Problems were solved by secondary school, high school and…

The inclusion of the practice of "developing and using models" in the "Framework for K-12 Science Education" and in the "Next Generation Science Standards" provides an opportunity for educators to examine the role this practice plays in science and how it can be leveraged in a science classroom. Drawing on conceptions…

In the study presented, as we report in this paper, we describe our theoretical and practical consideration to engage first-year pre-service teachers in proving activities in the context of a transition-to-proof course. We investigated how students argued to verify a claim of elementary number theory on entering university and compared the results…

Although research from a range of fields indicates the importance of innovation for progress in those fields, there is not yet a set of best practices for promoting insights that lead to scientific innovation. This article proposes and tests the hypothesis that function-construction maps based on prototype and heuristic theory lead to increased…

Ethical theories are key principles that determine right decisions and actions in morally problematic situations. Using phenomenological method of data collection, explication, and interpretative, the adolescent interviewees in this study revealed the essential nature, structure, content, and meaning of their personal moral beliefs and other…

Individual person fit analyses provide important information regarding the validity of test score inferences for an "individual" test taker. In this study, we use data from an undergraduate statistics test (N = 1135) to illustrate a two-step method that researchers and practitioners can use to examine individual person fit. First, person…

There are many decision-making theories that explain how people decide to buy, click, read, or skip something online. Studies integrating the eye tracking methodology with decision-making processes state many assumptions. Based on a group of assumptions, the current study aims to compare the two search contexts and find if the assumptions are…

This article proposes a heuristic that teachers and students can use together to create a vocabulary for discussing the aesthetic aspects of color and typography in document design work. By using this framework, teachers and students can generate a collection of shared "visual topoi" or commonplaces for describing the aesthetic value of…

Visual inspection of luggage using X-ray technology at airports is a time-sensitive task that is often supported by automated systems to increase performance and reduce workload. The present study evaluated how time pressure and automation support influence visual search behavior and performance in a simulated luggage screening task. Moreover, we…

The main aim of this research is to examine the effect of an instructional design based on the Algo-Heuristic Theory of Instruction (AHTI) on students' mathematics performance and logical thinking skills in the subject of 7th grade mathematics. The research is grounded in a mixed method. In the quantitative part of the research, a…

The purpose of this study was to investigate the development of pre-service chemistry teachers' (PCTs') argumentation skills in a laboratory course throughout a semester. A case study design was utilised. A total of six PCTs participated in the study. To investigate the development of PCTs' argumentation skills, the laboratory reports that were in…

NP-complete problems such as the traveling salesman problem (TSP) play a prominent role in most advanced undergrad/graduate courses in discrete optimization modeling. Teaching such an important topic from a purely mathematical perspective without discussing specific applications may result in reduced student interest and motivation. The DeLand…

The study evaluated usability of the "Opón-Ìmo" Technology Enhanced Learning System ("OTELS"), an educational software deployed for teaching and learning across state-owned senior secondary schools in Osun State, Nigeria. It employed a descriptive research design of the survey type. Eight teacher-educators in Educational…

We investigated whether Tagalog-speaking children incrementally interpret the first noun as the agent, even if verbal and nominal markers for assigning thematic roles are given early in Tagalog sentences. We asked five- and seven-year-old children and adult controls to select which of two pictures of reversible actions matched the sentence they…
