Circle and disc are fundamental concepts introduced in middle school, forming the basis for many other mathematical ideas. Students often face challenges in comprehending circles, discs, and their basic elements. This research examines the processes of sixth-grade students in constructing circles, discs, and their essential components within a…

This paper reports the factors that three Year 11 mathematics students identified as influencing their choice to use a Computer Algebra System (CAS) for solving selected problems, some of which were expected to be outside their pen-and-paper (p&p) range. In individual interviews, the students were presented with eleven algebra problems and…

The prospective use of low fidelity simulation and gaming in aviation training is high, and may facilitate individual, personal training needs in usually asynchronous training setting. Without direct feedback from, or intervention by, an instructor, adaptivity of the training environment is in high demand to ensure training sessions maintain an…

The teaching of spoken Chinese in the context of post-primary education in Ireland faces several complexities. Learners of Mandarin Chinese as a Foreign Language (CFL), including both Irish and heritage learners, have demonstrated difficulty in learning spoken Chinese. This exploratory research is part of a larger project which aims to develop…

This paper introduces a new captioning tool, Partial and Synchronized Caption with Hints (PSCH), as a means to facilitate second language (L2) listening by providing cues for ambiguous and difficult words/phrases in the caption while filtering out the easy words. Each word in the caption is synchronized to the corresponding audio to enable…

Language teachers of the future, our current students, live in an increasingly technology-rich world. However, language students do not necessarily see their own digital practices as having relevance for guiding language learning. Research in the fields of CALL and language education more generally indicates that teaching practices change slowly…

Automatic Speech Recognition (ASR) technology has become a part of contemporary Computer-Assisted Language Learning (CALL) systems. ASR systems however are being criticized for their erroneous performance especially when utilized as a mean to develop skills in a Second Language (L2) where errors are not tolerated. Nevertheless, these errors can…

In our study we investigated second and foreign language (L2) sentence readability, an area little explored so far in the case of several languages, including Swedish. The outcome of our research consists of two methods for sentence selection from native language corpora based on Natural Language Processing (NLP) and machine learning (ML)…

Okazaki and Nitta (2005) developed an e-learning program called PLIMA (your Personal LIstening Manager) which focuses on improving poor phonological analysis such as the inability to hear liaison or unstressed sounds. However, the fact remains that there are certain types of liaison sounds that learners do not catch, and some types they do. This…

Why are some words harder to learn than others? In a long-term CASLR (computer-assisted second language research) study, a vocabulary flashcard program that employs spaced repetition for explicit vocabulary training was used in order to arrive at data on the difficulty of individual words. The vocabulary content of a beginner's Welsh course was…

This review of the literature on five learner control variables in computer-based instruction concludes that: (1) pacing left to learner control has been found ineffective because learners tend to procrastinate or to exit lessons prematurely; (2) sequence, or content flow, has been an ineffective variable left under learner control since…

Because of the lack of error-free, on-task performance by young children, cognitive modeling has not generally been considered an appropriate technique for characterizing computer use by young children. It is argued that cognitive modeling can be a useful strategy for organizing data on children's performance when the domain being studied is…

A research study was conducted to determine the effectiveness of using computer assisted instruction (CAI) to teach handwriting. Designed to take advantage of the computer's facility to rapidly transfer large amounts of precise data, the handwriting program used a computer-connected pen as the interface between learner and machine. Nine boys…

An application of the two-paramenter logistic (Rasch) model to tailored testing is presented. The model is discussed along with the maximum likelihood estimation of the ability parameters given the response pattern and easiness parameter estimates for the items. The technique has been programmed for use with an interactive computer terminal. Use…

This study investigated the characteristics of Computer-based Case Simulations (CCS) that may be associated with case difficulty. Difficulty was defined as the average rating by physicians of examinee performance on a nine-point scale or the passing rate on the cases. Two data sets were used, one from an administration of 18 cases to 201 medical…
