This study explores the potential to enhance the performance of convolutional neural networks (CNNs) for automated scoring of kinematic graph answers through data augmentation using Deep Convolutional Generative Adversarial Networks (DCGANs). By developing and fine-tuning a DCGAN model to generate high-quality graph images, we explored its…

Difficulties in understanding physics concepts are often experienced by students such as in the material of regular uniform motion. This study aims to describe the mental models of first-year secondary school students on regular straight-line motion. This research utilized a case study method of 167 students at the secondary level with an average…

A commonplace sight is seeing other people walk. Our visual system specializes in processing such actions. Notably, we are not only quick to recognize actions, but also quick to judge how elegantly (or not) people walk. What movements appear appealing, and why do we have such aesthetic experiences? Do aesthetic preferences for body movements arise…

Because of the condition of limited gross motor learning, especially in basic movements based on the play method for children aged (5-6 years) is the main problem in this study. This study aims to develop a learning model for non-locomotor, locomotor and manipulative basic movements as an effort to improve basic movement skills in students and…

Recent studies have identified an incomplete student understanding of how elastic rebound causes earthquakes. We hypothesized that realistic imaging of spatial patterns in ground motions over the course of the earthquake cycle would improve student understanding. Incorporating spatial change information in the form of both motion vectors and…

One of the aspects of programming that novices often struggle with is the understanding of abstract concepts, such as variables, loops, expressions, and especially Boolean operations. This paper aims to explore the effects of programming tools with different degrees of embodiment on learning Boolean operations in elementary school. To this end, 67…

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…

Student-generated drawings are known to be effective in building and revealing students' conceptions of chemistry. Some chemistry concepts, moreover, include changes and processes that cannot be merely represented by static drawings. Computer-based animations are needed to represent the dynamics. In this study, 25 chemistry student teachers, who…

Background: The American Psychological Association reports that Generation Z are suffering mentally and physically more than any other group. Purpose: Measure the effects of a 16-week, online college-level "Complementary Therapies in Health Course" through the lens of the biopsychosocial-spiritual model on measures of health and aspects…

The research orientation of the Department of technics, Faculty of Education, University of Hradec Kralove focuses on finding new ways for development of polytechnic and science education. The research is motivated by the fact that children's interest in technical and science subjects is decreasing in recent years in the Czech Republic. The…

Models that are used to predict and explain phenomena related to molecular vibration and rotation are ubiquitous in physical chemistry, and are of importance in many related fields. Yet, little work has been done to characterize student use and application of these models. We describe the results of a multi-year, multi-institutional qualitative…

Theories of perceptual decision making have been dominated by the idea that evidence accumulates in favor of different alternatives until some fixed threshold amount is reached, which triggers a decision. Recent theories have suggested that these thresholds may not be fixed during each decision but change as time passes. These collapsing…

Within the discussion of the development of commonsense theories of motion, recent research has established that throughout middle childhood, reasoning about motion down inclines changes with increasing age. To investigate this shift in more detail, this study investigated 5- to 11-year-old children's understanding of motion down curved slopes,…

In this article we present and discuss some theoretical and methodological elements of a wider research that analyzes the teaching practice of two teachers novice and expert from a semiotic theoretical approach. The conceptual framework of this work allows for addressing the epistemological and didactic dimensions of the teaching practice. Three…

This study aims to analyze the students' understanding of motion in straight line concepts and their difficulties after the learning process. The research method is a mixed method with an embedded experimental design. The research was conducted in one of the public senior high schools in Malang City Indonesia with 34 students consisting of 20…
