The article examines "task" as research construct as predominantly conceived in terms of task-as-workplan in the task-based learning/second language acquisition literature. It is suggested that "task" has weak construct validity and ontology in an overwhelmingly quantitative paradigm because the construct has a "split personality."…

Using grounded theory methodology, I establish family identity management as an important type of invisible work that connects women's household-based domestic activities with community members perceptions and treatment of them and their family members. Detailed observations of household routines and family interactions, as well as in-depth…

Awareness of optimal behaviour states of children with profound intellectual disability has been reported in the literature as a potentially useful tool for planning intervention within this population. Some arguments have been raised, however, which question the reliability and validity of previously published work on behaviour state analysis.…

In order to enable students who are blind and visually impaired to observe chemical changes in solutions, a hand-held device was designed to output light intensity as an audible tone. The submersible audible light sensor (SALS) creates an audio signal by which one can observe reactions in a solution in real time, using standard laboratory…

A multi-informant study investigated the association between deception capacities and subtypes of aggression in a young early childhood sample (M=44.65 months of age, SD=13.39, N=64). A newly developed teacher report of deception had appropriate psychometric properties (reliability, concurrent validity, and construct validity). Recently introduced…

This issue's scenario, To Participate or Not to Participate, describes an evaluator's shift in method from nonparticipant to participant observation. Although evaluation theorists differ on the extent to which methods decisions are ethical decisions (Morris, 1998), neither of the two commentators considers the methodological decision problematic;…

Recent studies have used pretreatment analyses, termed competing stimulus assessments, to identify items that most effectively displace the aberrant behavior of individuals with developmental disabilities. In most studies, there appeared to have been no systematic basis for selecting the sampling period (ranging from 30 s to 10 min) in which items…

Situation definition is the process and product of actors' interpretive activities toward a given situation. By reviewing a number of psychological studies conducted in experimental settings, we found that the studies have only explicated a part of the situation definition process and have neglected its dynamic aspects. We need to focus on the…

An attempt is made to put the notion of sample quartiles on a mathematical footing in the light of ranks of observations, and equisegmentation property that the quartiles divide ordered sample observations into four segments leaving the same number of observations in each if all the observations are distinct. Sample quartiles provided by the…

Rater bias has long been considered a source of error in observer ratings but has been ignored by process researchers using participant ratings. In particular, rater variance, or differences in generalized favorable or unfavorable perceptions of others, represents a neglected source of error in studies using participant ratings. The author…

We studied possible relations between seizures and problem behavior in 3 adults with developmental disabilities. Each person was observed for between 56 and 92 days to record occurrences of seizures and problem behavior. Results of our descriptive analysis indicated an association between seizures and problem behavior for each participant. For…

The National Council of Teachers of Mathematics (NCTM) asserts that a goal of mathematics education, in Prekindergarten through grade 12, is to develop mathematical power for "all" students, and that educational equity is the nucleus of this goal. Nevertheless, researchers have found that equity for all students in mathematics education has not…

One of the greatest challenges for those who study schools and their success in educating students is defining the characteristics of those organizations that are successful, and recognizing the variables that exist to support the actions of the members of the organization. In this era of assessment and accountability, school districts struggle to…

The objective of this paper is to explore the operation of magnet and professional development school (PDS) programs in a real life situation using an ethnographic study of Downtown Elementary School (DES--a pseudonym) that simultaneously operates as a PDS and a magnet school. The author spent almost three years at DES, located in the Southern…

Short stories are considered as good resources that can be used in language classrooms. Laine (1997) suggests that in foreign language classes where there are children who are not motivated and who are low achievers, a story, if it is well-chosen, can help change their attitudes to the language. And, the narrative (or storytelling) approach is…
