The purpose of this article is to address the issue that children's natural singing voices and pitch perception are in a treble range, and a male elementary general music teacher's natural singing voice is an octave below. There are many strategies to overcome this significant but manageable obstacle in daily teaching, including monitoring of…

With the increasing attention and surge of empirical research in providing academic instruction for students with autism spectrum disorder (ASD) comes the need to provide teachers with research-supported strategies. Using one evidence-based strategy for teaching mathematics to students with high incidence disabilities, and another for teaching…

According to Question-Under-Discussion (QUD) models of discourse interpretation, clauses cohere with the preceding context by virtue of providing answers to (usually implicit) questions that are situated within a speaker's goal-driven strategy of inquiry. In this article we present four experiments that examine the predictions of a QUD model of…

The purpose of this article was to describe a Finnish research project concerning communicative spontaneity in pupils with autism spectrum disorder (ASD). ASD is a behavioural syndrome which is neurobiological in origin and which involves atypical developmental dysfunctions in the brain. The essential features are persistent impairment in…

Voluntary shifts of attention are often motivated in experimental contexts by using well-known symbols that accurately predict the direction of targets. The authors report 3 experiments, which showed that the presentation of predictive spatial information does not provide sufficient incentive to elicit voluntary shifts of attention. For instance,…

In a contextual cuing paradigm, we examined how memory for the spatial structure of a natural scene guides visual search. Participants searched through arrays of objects that were embedded within depictions of real-world scenes. If a repeated search array was associated with a single scene during study, then array repetition produced significant…

Is object-based attention mandatory or under strategic control? In an adapted spatial cuing paradigm, participants focused initially on a central arrow cue that was part of a perceptual group (Experiment 1) or a uniformly connected object (Experiment 2), encompassing one of the potential target locations. The cue always pointed to an opposite,…

The Hint Factory is an implementation of our novel method to automatically generate hints using past student data for a logic tutor. One disadvantage of the Hint Factory is the time needed to gather enough data on new problems in order to provide hints. In this paper we describe the use of expert sample solutions to "seed" the hint generation…

Human skilled behavior requires preparatory processes that selectively make sensory and motor systems more efficient for perceiving the upcoming stimulus and performing the correct action. We review the literature concerning these preparatory processes as studied by response-cuing paradigm, and propose a model that accounts for the major findings.…

In this paper, we present a synchronous text-based communication tool, referred to as Adaptive Communication Tool (ACT), which provides capabilities for adaptation and personalization. ACT supports both the free and the structured form of dialogue. The structured dialogue is implemented by two types of Scaffolding Sentence Templates (SST); i.e.…

In 5 experiments, the authors tested whether the processing of nonconscious spatial stimulus information depends on a prior intention. This test was conducted with the metacontrast dissociation paradigm. Experiment 1 demonstrated that masked primes that could not be discriminated above chance level affected responses to the visible stimuli that…

This paper explores the possibility of integrating cognitive theory into an established instructional development model, i.e., Gagne's nine events of instruction. Based on the third edition of Gagne's book, this paper describes the most up-to-date notions of how cognitive theory impacts on this development framework. Each of the nine events is…

This study compared three models of adult prompting to promote communication acts of three toddlers. The responsive interaction model avoids the use of explicit prompts, whereas the milieu and didactic approaches encourage explicit prompts. Higher rates of intentional communication were found for the explicit prompt condition, although the minimal…
