This study investigated preservice secondary mathematics teachers' difficulties with and understanding of graphs of two-variable inequalities with the lens of the APOS theory. The analysis showed that most teachers understood inequality graphs as actions, at best, and used informal rules to construct graphs. They also had difficulty justifying…

Purpose: The purpose of this work is to illustrate the processes involved in managing teams in order to assist designers and developers to build software that support teamwork. A deeper investigation into the role of team analytics is discussed in this article. Design/methodology/approach: Many researchers over the past several decades studied the…

Considering the central role of identity in understanding teacher development, this paper addresses the ways in which pre-service language teachers envision their identities as future professionals. The paper is based on a qualitative study of 61 students' visualisations of their future work during their first semester in language teacher…

This article illustrates ways that dynamic software using some sophisticated techniques in Excel can be used to demonstrate fundamental ideas related to regression and correlation analysis to increase student understanding of the concepts and methods in elementary statistics courses and in courses at the college algebra/precalculus level that…

Visualization is an effective method for students to internalize concepts and to establish correlations between concepts. Visualization method is especially more important in mathematics which is perceived as the combination of abstract concepts. In this study, whether 6th grade students can solve questions about "Fractions" by using…

Previous studies revealed that many students cannot perform well when it comes to word problem-solving questions. There are various problem-solving strategies that can be applied to help students to overcome the problem. Visualisation techniques in learning have been used to help students enhance their conceptual understanding of the mathematical…

This study replicated a study conducted by Branch, Rezabek and Cochenour (1998) who contended that perception and interpretation can be influenced by the type of graphic elements used to compose a diagram. Because instructional design conditions resemble complex situations that require learning development systems sufficient to address the…

The purpose of this research was to compare mental and physical practice on acquisition of basketball free shot. Forty inexperienced boys were selected randomly by a revised questionnaire of motor imagery-making of Hall and Martin (1977). They were divided into 2 groups; an experimental group and a control one. Group one carried out the whole…

A teaching laboratory experiment is described where students prepare in vitro transcription reactions of a fluorescent RNA aptamer, named Broccoli, and observe the production of the aptamer in real-time on a fluorescence plate reader. Alternate visualization methods with minimal costs are also described for laboratories lacking this…

Research dispels the myth that teachers peak as professionals early in their careers, hitting a performance plateau after only a few years on the job. While most teachers keep honing and polishing their craft the longer they stay in the classroom, a fair number do not. Over the years, research on how experts in a variety of fields have continued…

"Creating the Visitor-Centered Museum" offers insight into why and how 10 case study museums have transformed to serve the needs of their public. Susan Spero interviews authors Peter Samis and Mimi Michaelson about the purpose of the book, their case study choices, the key characteristics of visitor-centered institutions and their…

This study utilizes an educational historical narrative research method to understand the unique viewpoint of Lowenfeld toward visualization as a holistic concept in progressive art education. Employing a social constructivist framework, it explores the problem that the emphasis in education on the surface elements of standardized subject-based…

Sports injuries are caused by physical activity that is done to spend leisure time or a more specialized purpose. The aim of this study was to investigate the role of psychological skills (basic, cognitive and psychosomatic) in reducing traumatic student injury at the University of Trabzon. The method of this research is descriptive and…

This study set out to assess the ability of year nine students to identify and classify the most likely natural and mixed risks, both on a national scale and within the Metropolitan Area of Porto (AMP). We also sought to assess the respective spatial perception of different risks at regional level. For this purpose, a questionnaire was applied and…

We present the analysis of the planetarium usage survey (PLUS), a two-part, mixed-methods initial study investigating planetarium use in the U.S. by undergraduate learners. Seventy-seven planetariums situated on college or university campuses within the U.S. completed an online survey during the fall of 2018 with 11 of those participating in…
