This dissertation presents a new tool for exploratory text analysis that attempts to improve the experience of navigating and exploring text and its metadata. The design of the tool was motivated by the unmet need for text analysis tools in the humanities and social sciences. In these fields, it is common for scholars to have hundreds or thousands…

The effects of a socially interactive robot on the conversational turns between four young children with autism and their mothers were investigated as part of the intervention study described in this research report. The interventions with each child were conducted over 4 or 5 days in the children's homes where a practitioner facilitated…

The e-Textbook and e-Schoolbag initiatives have received wide attention and have been seen as the trend towards future education. This paper describes the framework of e-Textbook and e-Schoolbag including its conceptual model and system model. It further discusses the five interconnected categories that form the main parts of this Ecosystem…

This large-scale effectiveness trial found a significant positive effect for high schools using Cognitive Tutor Algebra I (CTAI) in their second year of implementation, relative to similar schools that continued to use existing textbook-based algebra curricula. This positive result is important for educators and policymakers seeking ways to…

The expertise reversal effect occurs when learner's expertise moderates design principles derived from cognitive load theory. Although this effect is supported by numerous empirical studies, indicating an overall large effect size, the effect was never tested by inducing expertise experimentally and using instructional explanations in a…

Repositories with educational resources can support the formation of online learning communities by providing a platform for collaboration. Users (e.g. teachers, tutors and learners) access repositories, search for interesting resources to access and use, and in many cases, also exchange experiences and opinions. A particular class of online…

This article will discuss two teacher training functions: One function is to give the teacher candidates practice in evaluating currently available mathematics websites used in grades K-8 for mathematics instruction. The second function is the evaluation of data by teaching candidates of 13 commonly used math sites by middle and elementary…

The aim of the study was to find out a method designated to improve the learning of computer courses by adding Screencast technology. The intention was to measure the influence of high-quality clips produced by Screencast technology, on the learning process of computer courses. It was required to find out the characteristics (pedagogical and…

This pilot study evaluated users' perceptions of the effectiveness of the VineUp platform to match mentors from a large United States manufacturing firm and mechanical engineering students in an honors program at a small private university. Four mentor/mentee pairs were surveyed and interviewed at the end of the nine-month program. Although the…

This exploratory study introduces the systemic approach and the explicit teaching of a meta-language to provide conceptual tools for students for the analysis and interpretation of multimodal texts. Equipping students with a set of specialised vocabulary with conventionalised meanings associated with specific choices in multimodal texts empowers…

Evaluating promisingness of ideas is an important but underdeveloped aspect of knowledge building. The goal of this research was to examine the extent to which Grade 3 students could make promisingness judgments to facilitate knowledge-building discourse. A Promising Ideas Tool was added to Knowledge Forum software to better support…

Teachers are not typically involved as participatory designers in the design of technology-enhanced learning environments. As they have unique and valuable perspectives on the role of technology in education, it is of utmost importance to engage them in a participatory design process. Adopting a case study methodology, we aim to reveal in what…

The purpose of this study was to determine the effects of dynamic mathematics software on the achievement of pre-service mathematics teachers in the topic of polar coordinates and to solicit their opinions about computer-assisted instruction. The study was conducted for 11 weeks with 33 pre-service teachers in the Department of Mathematics…

This paper presents the dataset collected from student interactions with INQPRO, a computer-based scientific inquiry learning environment. The dataset contains records of 100 students and is divided into two portions. The first portion comprises (1) "raw log data", capturing the student's name, interfaces visited, the interface…

Science education can build a bridge between research carried out by scientists and relevant learning opportunities for students. The Broader Impact requirements for scientists by funding agencies facilitate this connection. We propose and test a model curriculum development process in which scientists, curriculum developers, and classroom…
