Species TOPOS is a free software package for generating three-dimensional (3-D) topographic surfaces ("topos") for acid-base equilibrium studies. This upgrade adds 3-D species distribution topos to earlier surfaces that showed pH and buffer capacity behavior during titration and dilution procedures. It constructs topos by plotting…

The national focus on teacher accountability and the resulting emphasis on raising the bar for teacher evaluations challenge teachers of students with learning disabilities (LD) to rethink instructional design and delivery. In response to these challenges, this article introduces a two-part protocol for planning and teaching strategy instruction…

Our purpose is to provide an exploratory statistical representation of initial teacher education as a complex system comprised of dynamic influential elements. More precisely, we reveal what the system looks like for differently-positioned teacher education stakeholders based on our framework for gathering, statistically analyzing, and graphically…

Today smartphones and tablets do not merely pervade our daily life, but also play a major role in STEM education in general, and in experimental investigations in particular. Enabling teachers and students to make use of these new techniques in physics lessons requires supplying capable and affordable applications. Our article presents the…

The objective of this study is to investigate the effect of the Pecha Kucha presentation format on English as foreign language learners' public speaking anxiety. The participants were 49 students in the English Translation and Interpretation Department of a state university in Turkey. A pre- and post-test experimental research design was used in…

Taking risks and enjoying challenges are fundamental to the lives of young children from a developmental and evolutionary point of view. However, in modern societies, increasing concern about dangers and injuries has led to the escalation in regulation and provisions for the safety of young children. This intent to establish secure and risk-free…

With emerging new technologies being applied in teaching and learning, this study compares visual representations in three different high school biology textbook formats and analyses the senses engaged in viewing and understanding the science content represented through these visuals. The findings show that while a similar pattern is observed in…

This study explores first-year university students' reasoning as they learn to draw Lewis structures. We also present a theoretical account of the formal procedure commonly taught for drawing these structures. Students' discussions during problem-solving activities were video recorded and detailed analyses of the discussions were made through the…

In this work, we present a teaching proposal which emphasizes on visualization and physical applications in the study of eigenvectors and eigenvalues. These concepts are introduced using the notion of the moment of inertia of a rigid body and the GeoGebra software. The proposal was motivated after observing students' difficulties when treating…

The following study was framed around a simple question: when a group of people is engaged in video conferencing, "what sort of things can they do to improve their group dynamics?" This is an important question for current and future educational practice because web-based video conferencing has increasingly become an important tool for…

This dissertation targets young students' developing knowledge relevant to a fundamental practice in academic mathematics: the use of diagrams to represent idealized mathematical objects whose properties are established by definition (as in the use of drawn dots to represent zero-dimensional points and drawn lines to represent one-dimensional…

The aim of this research was to examine the chemical representations that are present in Turkish high school chemistry textbooks. Content analysis was the method of analysis. Four chemistry textbooks, which were commonly used in Turkey, for each grade (i.e., from 9th to 12th), were selected. When evaluating the representations, a rubric including…

Objective: To evaluate the health education infographics posted on Twitter accounts by major health care institutions in Saudi Arabia. Method: Cross-sectional review of health education infographics using a semi-structured evaluation form. The scoring rubric included 10 criteria grouped under 4 main headings: (1) usefulness, (2) legibility, (3)…

With the emergence of interventions shown to reduce school discipline disparities, it is important to explore what variables influence educators to implement these approaches. In-depth interviews were conducted with a purposeful sample of 21 educators asked to describe their experiences implementing an equity-focused Positive Behavioral…

This paper presents a phenomenological diagnosis of the implementation of ProDuct-based Instruction (PDI) in EFL's writing class in Thailand contexts. PDI is a new instructional method for teaching business English writing. Its key is in the products that are tangible and appeal to human senses; the product's tangibility serves as a scaffold to…
