A variation of the Mantel Haenszel procedure is proposed that improves detection rates of nonuniform differential item functioning (DIF) without increasing the Type I error rate. The procedure, which is illustrated with simulated examinee responses, involves splitting the sample into low- and high-performing groups. (SLD)

This study examined how five normally developing two-year-old children manage the relationship between phonetic production and production of word combinations in their spontaneous speech. Results revealed tradeoffs between complexity of word combinations and both accuracy of consonant production and phonetic complexity of individual lexical items.…

Fifty-two subjects competed on a task against themselves, a difficult competitor, and an easy competitor. Certainty, ability attribution, and task satisfaction for those with low self-esteem were affected by perceived goal difficulty but not for those with high self-esteem. Low self-esteem groups had lower goals, certainty, and task performance.…

Analyzed the growth of a theoretical-research program in information needs and seeking studies by reconstructing the logical structure of the theories and by comparing conceptual and factual similarities. Found the program to be progressive in terms of empirical support and precision of theories, and elaborative in its growth pattern. Presents…

Examined the assumption that matching difficulty levels of test items with an examinee's ability makes a test more efficient and challenged this assumption through a class of one-parameter item response theory models. Found the validity of the fundamental assumption to be closely related to the van Zwet tail ordering of symmetric distributions (W.…

This study examined the influence of argument-MA-structure complexity on the omission of auxiliary "be" verbs in 30 children with specific language impairment (SLI). Results indicated that the children with SLI and controls matched for mean length of utterance were more likely to omit the auxiliary forms when attempting sentences with greater…

Although much has been discovered about relations between self-efficacy and academic achievement, questions remain about links between achievement, the structure of learning tasks, and changes in students' self-efficacy as students engage with a single, complex authentic task. Students' self-efficacy for learning (SEL) and for performance (SEP)…

It is shown that in the context of the Model with Internal Restrictions on the Item Difficulties (MIRID), different componential theories about an item set may lead to equivalent models. Furthermore, we provide conditions for the identifiability of the MIRID model parameters, and it will be shown how the MIRID model relates to the Linear Logistic…

Designing developmentally appropriate learning experiences requires an understanding of an instructional strategy known as simplification. Simplification, as the term implies, reduces the level of difficulty of a task, or some aspect of a task, for the learner. This article presents ideas regarding implementation of this strategy to accommodate a…

Learning of a procedural motor-skill task is known to progress through a series of unique memory stages. Performance initially improves during training, and continues to improve, without further rehearsal, across subsequent periods of sleep. Here, we investigate how this delayed sleep-dependent learning is affected when the task characteristics…

No published studies have sufficiently focused on essay topic writability from the perspective of college writers of the new millennium including native English speakers and ESL speakers. In this study, 500 college writers in Metro Toronto in Canada were interviewed to uncover if they found some essay topics easier than other topics. The results…

Advances in technology have caused a major shift in how students spend their time and challenged curriculum development to maintain interest and focus in the classroom. Implications are most profound in issues related to literacy due to a lack of experience and interest in reading. This article explores this issue and how it relates to teaching…

Increased numbers of elementary and secondary students with learning and other disabilities are participating in inclusive science classrooms. Unfortunately, many of these students struggle to achieve at a level commensurate with their peers. As a result, few students with disabilities pursue advanced scientific coursework or enter science,…

Conventional testing systems usually give students a score as their test result, but do not show them how to improve their learning performance. Researchers have indicated that students would benefit more if individual learning guidance could be provided. However, most of the existing learning diagnosis models ignore the fact that one concept…

Evaluation is an unavoidable feature in any teaching or learning scenario. The evaluation strategy of students differs widely throughout the world. Further, most of the institutes do not use any objective technique to assess the teaching performance of a teacher. The present paper defines performance metrics both for student and teacher evaluation…
