This dissertation conducted a science classroom intervention using two instructional approaches, computational modeling and paper-based pictorial modeling, in the context of food webs. A series of research papers were written on the impact of the intervention on students' attitudes and learning, and on teachers via professional development and…

Some low- and middle-income countries (LMICs) aim to designate the information and communication technology (ICT) sector as a central pillar to expedite their economic development, and a key element of ICT sector development is to nurture capable ICT workers. Scholars and policymakers concerned with those ICT workers tend to focus on nurturing…

This study investigates how second language (L2) fluency is influenced by two factors: Pre-task planning and content familiarity. Planning was adopted as a between-participant variable, combined with content familiarity as a within-participant variable, in a 2 × 2 split-plot factorial design. Nineteen measures of fluency phenomena, constituting…

Contribution: An approach is presented to provide contextualized feedback for students using a project management (PM) tool. This approach covers the ten PM knowledge areas, guiding students through the planning of software projects. Background: Because software PM is unfeasible without the support of a PM tool there is a growing demand that these…

This article explores the feasibility of employing cooperative program editing tools in teaching programming. A quasi-experimental study was conducted, in which the experimental group co-edited the programs with peers using the wiki. The control group co-edited the programs with peers using only the face-to-face approach. The findings show that…

A key insight from studies of gender segregation is that the allocation of different groups to different positions in the labour market is strongly related to ascribed status. Shared gendered cultural beliefs generally portray men as more competent and of a higher status than women, and position some workers as more suited than others to perform…

The new Advanced Placement (AP) Computer Science (CS) Principles course increases the need for quality CS teachers and thus the need for professional development (PD). This article presents the results of a 2-year study investigating how teachers teaching the AP CS Principles course for the first time used online PD material. Our results showed…

During the last few years, there has been a growing interest in students getting engaged in digital game-making activities so as to enhance their thinking skills. The findings of studies that have examined the impact of such initiatives are quite positive, especially concerning the promotion of 21st century skills; however, many students seem to…

Students nowadays are hard to be motivated to study lessons with traditional teaching methods. Computers, smartphones, tablets and other smart devices disturb students' attentions. Nevertheless, those smart devices can be used as auxiliary tools of modern teaching methods. In this article, the authors review two popular modern teaching methods:…

Linux Laptop Orchestra (L2Ork), founded in 2009 in the Virginia Tech Music Department's Digital and Interactive Sound & Intermedia Studio, "explores the power of gesture, communal interaction, and the multidimensionality of arts, as well as technology's potential to seamlessly integrate arts and sciences with particular focus on K-12…

A growing number of initiatives around the country are attempting to expose students to hands-on computer science (CS) curriculum and courses--and to address documented disparities in CS education. Answering the call for computer science expansion and equity, the New York City Department of Education (NYCDOE) launched the CS4All initiative in…

The purpose of this action research study was to measure the transactional distance of computer science students who participated in an online virtual community after completing a college preparation program. Using data and results generated from previous cycles of research I developed and moderated an online virtual community designed to lessen…

The increasing complexity of the new breed of distributed intelligent systems, such as the Internet of Things, which require a diversity of languages and protocols, can only be tamed with design and programming best practices. Interest is also growing for including the human factor, as advocated by the "ambient intelligence" (AmI)…

Current debates around the concept of boundary crossing stress the importance of boundary objects in bringing people together to share understandings. We argue that the boundary object is of secondary importance, and that what is important for the transformational potential of interdisciplinary understanding is opportunities for "boundary…
