The typical trigonometry, precalculus, or calculus student might not agree that logarithms are hot stuff, but we drew motivation from chili peppers to help students get a better taste for logarithms. The Scoville scale, which ranges from 0 to 16,000,000, has been the sole quantitative metric to measure the pungency (spiciness) of peppers since its…

Commonly used in research settings, noncontingent reinforcement (NCR) is a function-based intervention for decreasing challenging behaviors (Carr, Severtson, & Lepper, 2009). Function-based interventions effectively change behavior through detailed analysis of why the behavior occurs (Lane, Kalberg, & Shepcaro, 2009). Practitioners…

Multiple-stimulus without replacement preference assessment is a research-based method for identifying appropriate rewards for students with emotional and behavioral disorders. This article presents a brief history of how this technology evolved and describes a step-by-step approach for conducting the procedure. A discussion of necessary materials…

Selective mutism is a relatively uncommon, yet significantly impairing anxiety disorder that causes difficulties in young children when communicating in social situations (such as school) even though they speak normally when they are comfortable (such as at home). Early childhood educators play a unique role in helping to identify selective…

Designers try to "enlist" whatever they can to help themselves arrive at high quality, novel and original designs. When stimuli are used for this purpose, usually provided at the onset of the design process, these stimuli, or sources, may have one of two effects: they may enhance the design search and contribute to a high-quality, creative design,…

Clinical behavior analysis often targets the shaping of clients' functional interpretations of/or rules about his own behavior. These are referred to as clinically relevant behavior 3 (CRB3) in functional analytic psychotherapy (FAP). We suggest that CRB3s should be seen as contingency-specifying stimuli (CSS), due to the their ability to change…

This paper argues that design fixation, in part, entails fixation at the level of meta-representation, the representation of the relation between a representation and its reference. In this paper, we present a mathematical model that mimics the idea of how fixation can occur at the meta-representation level. In this model, new abstract concepts…

A very common cause of children's behavior disorder disturbance is an entity described as the hyperkinetic impulse disorder. This is characterized by hyperactivity, short attention span and poor powers of concentration, irritability, impulsiveness, variability, and poor schoolwork. The existence of this complexity may lead to many psychological…

A case is described of the development of a lesson plan for 10th grade (age range 15-16) chemistry classes on the chemistry of shower gels. The lesson plan follows a socio-critical and problem-oriented approach to chemistry teaching. This means that, aside from learning about the basic chemistry of the components making up modern shower gels in…

This article describes techniques that can be used to enhance mathematics instruction for English language learners. Using the strategies suggested in this article, such as scaffolding instruction and accommodating their linguistic needs, mathematics teachers can help ELLs both succeed and increase their mathematics achievement. (Contains 3…

Early and intensive behavioral intervention (EIBI) has been established as an effective treatment for autism. However, the complexity and intensity of EIBI programs make it difficult to fully report all critical aspects of the independent variable. Consequently, scientific reports of EIBI outcomes have been criticized for providing less than…

Two young boys with autism who used the picture exchange communication system were taught to solve problems (improvise) by using descriptors (functions, colors, and shapes) to request desired items for which specific pictures were unavailable. The results of a multiple baseline across descriptors showed that training increased the number of…

Ratcliff (1985) simulated data from three letter-matching experiments with his diffusion model. The necessity of including a comparison criterion is consistent with the conclusion of Proctor, Rao, and Hurst (1984) that bias of response criteria, alone, is insufficient to generate the fast-same phenomenon.

A model of information processing has been developed that combines concepts from the study of attention and the study of problem solving. The model has been realized as a computer program and used to simulate a variety of phenomena from the attention and performance literature. (Author/LMO)

In this article, the authors describe a varied day of stimulating mathematics with key stage 2 learners--all revolving around chocolate. They used a variety of stimuli organized around the chocolate theme. A whole day was spent on using and applying mathematics, and the exercise proved to be enjoyable for both staff and pupils. The children…
