Adaptive learning technology solutions often use a learner model to trace learning and make pedagogical decisions. The present research introduces a formalized methodology for specifying learner models, logistic knowledge tracing (LKT), that consolidates many extant learner modeling methods. The strength of LKT is the specification of a symbolic…

From a psycholinguistic perspective of view, there are many cognitive differences that matter to individuals' second-language acquisition (SLA). Although many computer-assisted tools have been developed to capture and narrow the differences among learners, the use of these strategies may be highly risky because changing the environments or the…

Spaced repetition is among the most studied learning strategies in the cognitive science literature. It consists in temporally distributing exposure to an information so as to improve long-term memorization. Providing students with an adaptive and personalized distributed practice schedule would benefit more than just a generic scheduler. However,…

Because a large number of Chinese characters are commonly used in both Japanese and Chinese, Chinese-speaking learners of Japanese as a second language (JSL) find it more challenging to learn Japanese functional expressions than to learn other Japanese vocabulary. To address this challenge, we have developed "Jastudy," a…

Previous research has shown that there is a time cost (i.e., a resumption lag) associated with resuming a task following an interruption and that the longer the duration of the interruption, the greater the time cost (i.e., resumption lag increases as interruption duration increases). The memory-for-goals model (Altmann & Trafton, 2002)…

In the current document, an integrative CBT-TTF framework is created, which proposes: technologies that require large amounts of working memory are best at improving outcomes that require little working memory to develop, and vice versa. Then, a meta-analysis of virtual reality (VR) training programs (which require great amounts of working memory)…

The rapid advancement in the capabilities of computer technologies has made it easier to design and deploy dynamic visualizations in web-based learning environments; yet, the implementation of these dynamic visuals has been met with mixed results. While many guidelines exist to assist instructional designers in the design and application of…

This study examined how 2 kinds of help when learning from text and pictures (mapping support and instructional guidance through prompts) influence the coherence formation process of integrating information into a mental model. It also explored spatial abilities and working memory span as potential moderators. In a computer-based setting, 84…

This paper examines the cognitive processes associated with higher-order thinking strategies--i.e., cognitive processes directly associated with the employment of knowledge in the service of problem solving and creativity--in order to more clearly define a prescribed instructional method to improve problem-solving skills. The first section of the…

Empirical studies that focus on the impact of three-dimensional (3D) visualizations on learning are to date rare and inconsistent. According to the ability-as-enhancer hypothesis, high spatial ability learners should benefit particularly as they have enough cognitive capacity left for mental model construction. In contrast, the…

Researchers have regarded inductive reasoning as one of the seven primary mental abilities that account for human intelligent behaviours. Researchers have also shown that inductive reasoning ability is one of the best predictors for academic performance. Modelling of inductive reasoning is therefore an important issue for providing adaptivity in…

Presents the transcript of an interview with Roger Schank that focused on the use of goal-based scenarios (GBS) for business training. Highlights include traditional approaches to business training and education; human memory models; advantages of GBS; and the value of computers in a GBS learning environment.

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…

Presents model of instructional strategy planning that links specific cognitive learning and thinking processes with specific computer-based instructional strategies. Topics discussed include memory systems; types of knowledge; drill and practice; tutorials; task-oriented simulations; problem-oriented simulations; and self directed experiences.…
