In this case study, we investigate three Chinese boys' self-efficacy beliefs learning English as a second language across English language learning tasks and home-based and school-based contexts. Participants reported higher self-efficacy to complete listening and speaking activities than during reading and writing activities. All participants…

Computer-assisted instruction systems have been broadly applied to help students solve math word problem. The majority of such systems, which are based on an instructor-initiating instruction strategy, provide pre-designed problems for the learners. When learners are asked to solve a word problem, the system will instruct the learners what to do.…

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…

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…

A simple technique, developed by A. Phillips (1987) is used to approximate the covariance between the Mantel-Haenszel log-odds-ratio estimator for a 2 x 2 x k table and the sample marginal proportions. These results are then applied to obtain an approximate variance estimate of an adjusted risk difference based on the Mantel-Haenszel odds-ratio…

The Mantel-Haenszel (MH) procedure has become one of the most popular procedures for detecting differential item functioning. Valid results with relatively small numbers of examinees represent one of the advantages typically attributed to this procedure. In this study, examinee item responses were simulated to contain differentially functioning…

The effects of test difficulty on the perception of examination difficulties and state anxiety are investigated. Thirty undergraduate students were administered the Educational Psychology Recognition Test and Test Perception Inventory to assess task difficulty and perception of exam difficultness. A modified version of the State-Trait Anxiety…

Difficulty levels of 168 randomly generated multiplication problems were obtained by testing 238 fifth-graders. Variables concerning the number of operations, digits carried, and magnitude of the digits were defined, and a least-squares procedure was used to construct structural models accounting for 60-70 per cent of observed problem difficulty…

Based on a PhD dissertation submitted to the University of Illinois.

One of a series of reports on the International Project for the Evaluation of Educational Achievement (in Mathematics).

The study investigated the effect of "item density" on item difficulty in passage-related language tests. Item density refers to the number and frequency of items in relation to clear text. The format used was a passage with underlinings to signal the language situations out of which the items were constructed. American College Testing…
