In a spiral galaxy, the stars move in a circular motion around the galactic center, and the relation between velocity and the orbital radius is referred to as the rotation curve. Previous astronomical observation data indicate that the rotation curve is flat at the periphery of the galaxy, which completely dissatisfies Keplerian decline. Assuming…

In this study, how prospective chemistry teachers (PCTs) perceive precipitation and conceptualize precipitation reactions at the symbolic level was explored. Further, it was of interest to identify PCTs' visualization of the sub-microscopic level of precipitation reactions. The sample was drawn from the Chemistry Education Department at the…

Purpose: The purpose of this paper is to describe examples of the application of learning analytics (LA), including the assessment of subject grades, identifying subjects that need revision, student satisfaction and cohort comparisons, to program curriculum review. Design/methodology/approach: Examples of analyses that address specific questions…

Past research has shown that children's mental rotation skills are malleable and can be improved through action experience--physically rotating objects--or gesture experience--showing how objects could rotate (e.g., Frick, Ferrara, & Newcombe, 2013; Goldin-Meadow et al., 2012; Levine, Goldin-Meadow, Carlson, & Hemani-Lopez, 2018). These…

The aim of this article is to provide a theoretical framework to strengthen design thinking and practice in the context of teaching through productive processes and using it to generate knowledge. The article explores three modes of inquiry inspired by Dewey and based on Schön, Barab & Squire and DiSalvo to investigate academic inquiry in…

As students learn physics, they are often required to reason about the behavior of macroscopic and microscopic phenomena, and to synthesize prior knowledge from several different areas of physics to construct understanding of new ideas. This can be a tremendously difficult cognitive task for novice students, especially when the unfamiliar…

Three experiments investigated the relationship between future thinking and false memories. In Experiment 1, participants remembered familiar events (e.g., a holiday) from their past, imagined planning the same events in the future, or took part in a control condition in which they visualized typical events. They then rated a series of…

The skill of spatial learning and orientation is fundamental in humans and differs widely among individuals. Despite its importance, however, the malleability of this skill through practice has scarcely been studied empirically, in contrast to psychometric spatial ability. Thus, this article examines the possibility of improving the accuracy of…

The geosciences consist of multiple disciplines including geology, oceanography, and atmospheric science. Significant work expended to understand spatial thinking skills important to teaching and learning geology has advanced our ability to support students in geology courses and to achieve increased student success, retention, and diversity in…

Citespace, a visualization-based analysis tool, has been used to analyze the literature data by visualizing the patterns and potential trends of a field. Previous studies show that when used for analyzing the literature in Chinese, Citespace could only conduct very basic analysis, different from its use in analyzing the literature data in English.…

This study aims to use problem solving techniques in solving problems at different stages step by step. The theoretical and experimental semiotic model was developed by using the semiotic model method, which can be established with the relation of priority-recency, and an analysis of the problem solving skills of the students was made. Given that…

Even though drawing, as a form of learning, has been confined to disciplines such as fine arts and graphics design, there is evidence that drawing can be an important heuristic device for teaching college students. However, the use of drawing as a pedagogy in teaching sociology is undeveloped. The article starts by discussing the theoretical…

Technological advances, artificial intelligence innovations, and widespread computing have all combined to necessitate a new generation of knowledge workers where data becomes a ubiquitous part of decision making (Sutton, 2006). Teaching today's students through the application of this "new" knowledge to long-established fields…

The work deals with the study of the roots of the characteristic polynomial derived from the Leonardo sequence, using the Newton fractal to perform a root search. Thus, Google Colab is used as a computational tool to facilitate this process. Initially, we conducted a study of the Leonardo sequence, addressing it fundamental recurrence,…

Augmented reality (AR) is a means of superimposing artificial 3D objects over the real world via a mobile device. An AR standard file format has been recently implemented on mobile devices that current students commonly own. Here we describe three relatively nontechnical methods to produce 3D AR objects for chemistry courses and demonstrate their…
