Student modeling can help guide the behavior of a cognitive tutor system and provide insight to researchers on understanding how students learn. In this context, Bayesian Knowledge Tracing (BKT) is one of the most popular knowledge inference models due to its predictive accuracy, interpretability and ability to infer student knowledge. However,…

Teaching is considered one of the most trusted professions, yet literature evaluating teachers' understanding of professional behaviour is scarce. Recently, technological advancements such as Social Networking Sites (SNS; e.g. Facebook) have created fresh debate about appropriate behaviour for teachers: in school and online. The "Professional…

The term "problem" has been poorly defined in the literature on the research process. The author has attempted to define the term more specifically than as an instance of indeterminacy. It can be determined as one of four instances of indeterminacy: anomaly, unverified facts, uncharted areas, or conflicting evidence. In each of these…

An investigation was undertaken into the possibility of automatically detecting how concepts exist in relation to each other in abstracts, a text-type commonly used in free-text retrieval. The end goal of this research is to capture these relationships in structured representations of abstracts' contents so that users can require not only that the…

The importance of validity and reliability in the componential analysis of human intelligence is discussed. The roles of construct, internal, external, convergent, discriminant, and ecological validity in componential analysis are outlined. Within-replication (internal-consistency) and between-replication (alternate-forms or test-retest)…

Six points of view regarding the future of intelligence testing are considered, and a "prototypical" point of view is presented. The past history and present status of intelligence testing and research are considered. Their future is discussed in terms of assessment of various kinds of components of intelligence. (Author/RD)

A two-year study that attempted to measure patterns of pupil attributions for success and failure in mathematics is reviewed. An attribution pattern variable (ATTPAT) was created to categorize individuals studied into three groups. The first group had an attribution pattern thought to lead to generalized low expectancies for success. Students…

This paper presents an ethnographic analysis of a controversial research project, the Putaney Study, as an argument for the involvement of anthropologists in research that is perceived to be potentially controversial. A research team from Putaney University initiated a research project to document the fertility attitudes and practices of 600…

A comparison of the application of two current theories of stress to a particular stress pattern found in the Salish language Sooke is presented. Hammond's (1986) grid-like tree structure representation of stress is compared with Halle and Vergnaud's (1986) tree-like grid structure. Examples in the Australian language Maranungku show that, in…

An investigation, analyzing the linking of skeleton and syntactical rules of Madurese, presents counterevidence to Marantz's claims about the nature of reduplication, and to Carrier-Duncan's claim that reduplication must precede all phonological rules. It is proposed that reduplication in Madurese is not affixation, as Marantz claims, and can be…

Lexical semantics and contrastive lexical semantics can serve as a background discipline to describe and, to some extent, to explain errors in interlanguage. Two developments in lexical semantics that are relevant in this area are the description of sense-relationships and componential analysis. Contrastive lexical semantics involves mapping the…

The 1899-1908 Lake Placid Conferences' definition of home economics as a professional field of study was compared to the 1979 meaning in Home Economics: A Definition, a paper by Brown and Paolucci, to provide clarity and future direction for the field. A componential analysis was conducted with the following domains: family, religion, politics,…

Two concerns labeled as fundamental to the field of curriculum are identified: (1) the identification of educational content, and (2) the development of ways to make it available to young people. These factors are reviewed from the perspective of their influence on the mathematics curriculum, with note that the critical integral relationship…

The specification in concrete behavioral terms of theoretical constructs is one difficulty associated with behavioral assessment. For example, the construct of heterosocial skill has not been successfully defined in operational terms. A linear modeling technique was used to identify valid behavioral referents of heterosocial skill ratings for both…

This paper examines the semantic structure of antonyms on the basis of some examples taken from Romanian. Both grammatical and lexical antonyms are considered with a view toward grasping the correspondence and differences between the two classes. Representative examples illustrate the following conclusions: (1) the distinction between lexical and…
