Spatial ability is an ability to visualize an object in space. In learning geometry, the spatial ability is required to solve geometric problems. One of the learning models that can be applied in the learning process to improve students' spatial ability is Van Hiele learning model. Van Hiele learning model is a learning model based on Van Hiele…

A set of web-based stereochemistry tools which help students use virtual 3D models to translate Newman projections and chair conformations and assign "R/S" labels to stereocenters from 2D dashed-wedged structures is described. These tools are unique in the way they link 2D dashed-wedged structures to 3D models to help students develop…

Computational thinking requires high cognitive load as students work to manage multiple tasks in their problem-solving environment. Through research in K-2 classrooms on computational thinking, we noticed that students lack the representational fluency needed to move from one form to another--such as moving from physical to more abstract…

With a rising aging population, it is important to develop behavioral tasks that assess and track cognitive decline, and to identify protective factors that promote healthy brain aging. Mnemonic discrimination tasks that rely on pattern separation mechanisms are a promising metric to detect subtle age-related memory impairments. Behavioral…

A pretest-training-posttest design assessed whether training to improve spatial skills also improved mathematics performance in elementary-aged children. First grade students (mean age = 7 years, n = 134) and sixth grade students (mean age = 12 years, n = 124) completed training in 1 of 2 spatial skills-spatial visualization or form…

Design research was conducted to investigate the development of dynamic conceptions of area. Students used simple physical instruments, squeegees, and paint, to generate rectangular areas continuously as a sweeping motion of one length through another. Then, they dissected the resulting swept space into discrete units of measure by coordinating…

In this paper, we examine the conceptual understanding and experiences that students in German secondary schools have of boundaries. For our research we conducted qualitative interviews and surveys (interviews n=20; surveys n=21) with children (aged 14-17) born both in Germany and with refugee backgrounds. We asked for the children's conceptual…

Despite the plethora of research in the field of mental rotation, researchers are still divided over a range of related issues, particularly the processes involved in coping with mental rotation tasks. This field of research, for the most part, is descriptive rather than interpretative, leading to the absence of a theoretical framework to enable…

Successful episodic memory requires binding of event details across spatial and temporal gaps. The neural processes underlying mnemonic binding, however, are not fully understood. Moreover, although acute stress is known to modulate memory, if and how stress changes mnemonic integration across time and space is unknown. To elucidate these issues,…

Drawing is one of children's modes of communication which has recently excited academic inquiry in non-Western cultures. It is the means through which children express their fears, desires, anxieties and conception of phenomena. This study investigated drawings by four- to ten-year-old Botswana children in response to the human figure as an…

The main purpose of this study was to assess children's skill in using a simple map. The study was conducted among 262 children (141 girls and 121 boys), aged between 61-78 months (average 71 months), attending to 4 public pre-schools in Istanbul, Turkey. The simple map skills (requiring mental rotation and understanding spatial relation) of the…

Decades-old research has demonstrated the effects of virtual space on perception mostly with adult samples. Little is known about children's ability to utilize spatial-temporal qualities from computerized settings. Past research with primary school children suggested that the ability to utilize spatial-temporal information is crucial for inferring…

Research has demonstrated strong relations between spatial skill and mathematics across ages and in both typical and atypical populations, suggesting that a significant proportion of variance in mathematics performance can be explained by variance in spatial skill. Why do these relations exist and how do they develop? Studies of dimensionality in…

This paper focuses on examining the effectiveness of three-dimensional (3D) computer models on student teachers' academic achievement, mental model construction, and spatial ability used in learning the "atomic models" topic in this study. The students were randomly assigned into two groups: the treatment group (TG) where 3D computer…

The main objective of this experimental study was to reveal the importance and effectiveness of the Geographic Information Systems (GIS) based materials in the course of the earthquake topic to high school 10th grade students. The selected topic of the study was "The relationship between faults, plate movements and earthquakes in…
