In this dissertation I set out to solve a series of puzzles related to the notion of a DP periphery, defined as an area around the edge of a given domain targeted by operations such as movement and agreement. In solving these puzzles, I argue for a peripheral area in the nominal domain. Early arguments for a peripheral boundary in the nominal…

Background: Research on the relationships between parental factors and children's executive function (EF) has been conducted mainly in Western cultures. Aim: This study provides the first empirical test, in a non-Western context, of how maternal EF and parenting behaviours relate to child EF. Sample South Korean mothers and their preschool…

The Tower of Hanoi is an old, popular, and engaging puzzle. It is an exceptional puzzle too considering how effective it can be in engendering multiple valuable outcomes when used as a tool for learning. One of the fundamental goals of mathematics teacher preparation is to enable the prospective teacher to develop mathematical habits of mind and…

This work presents the assessment of the development and evolution of an active methodology (Project-Based Learning--PBL) implemented on the course "Unit Operations in Environmental Engineering", within the bachelor's degree in Environmental Engineering, with the purpose of decreasing the dropout rate in this course. After the initial…

Emerging technologies have been widely used in applications designed to increase potential for learning enhancement. This study develops a mobile application to integrate augmented reality (AR) functionality into physical puzzle-type games. In the application, learners see visualizations of three-dimensional (3D) dinosaurs and interact with…

The aim of this study is to investigate whether maternal spatial support during two types of joint manipulative toy play tasks with 2-year-old children was longitudinally associated with math screening test scores in second grade. The interaction between spatial support and maternal education was explored as well. We also investigated predictions…

This study explores the differences between face-to-face (FTF) interaction and text-synchronous computer-mediated communication (SCMC) regarding corrective feedback (CF). Eight native speakers (NSs) and eight second language learners were paired up and divided into two groups: instructed and uninstructed. Native speakers in the instructed group…

Participation in synchronous online learning is an increasing need for students' learning outcomes. Teachers generally cannot be sure about the fact that students who are seen in the participation lists are really following the online tasks. Recent studies have shown that gamification can be an effective way to support learners' participation in…

Background: Teaching English as home language (EHL) could be a complicated process in a country like South Africa, where there are eleven official languages operating in a multicultural society. This requires capacitating teachers with appropriate and relevant strategies to strengthen their teaching, especially in the foundation phase. Aim: This…

A science video blog, which has gone viral, shows a wooden block shot by a vertically aimed rifle. The video shows that the block hit dead center goes exactly as high as the one shot off-center. (Fig. 1). The puzzle is that the block shot off-center carries rotational kinetic energy in addition to the gravitational potential energy. This leads a…

Longitudinal spatial language intervention studies have shown that greater exposure to spatial language improves children's performance on spatial tasks. Can short naturalistic, spatial language interactions also evoke improved spatial performance? In this study, parents were asked to interact with their child at a block wall exhibit in a…

Math is increasingly recognized as a critical part of what young children are exposed to and learn in early childhood programs. Geometry is one of three focal areas emphasized for early childhood, and opportunities for geometry learning are present in many manipulatives present in early childhood classrooms. Yet geometry remains an understudied…

Efficacy of games as learning medium is of interest to researchers and the gaming industry. A critical metric for learning is knowledge retention and very few studies have conducted in-depth comparisons of: a) game versus no-game learning, b) collaborative versus individual learning. Towards this, the study reported in this article will present…

We present in this work a demonstration of the maze-solving problem with electricity. Electric current flowing in a maze as a printed circuit produces Joule heating and the right way is instantaneously revealed with infrared thermal imaging. The basic properties of electric current can be discussed in this context, with this challenging question:…

The use of current and emerging tools in education is becoming a blistering topic among educators and educational institutions. Gaming in education may be viewed as an interference to learning but its role in education is to increase students' motivation and engagement, to enhance visual skills, to improve students' interaction and collaboration…
