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…

This study used direct assessments of language arts, mathematics and independent functioning, as well as parent interviews and teacher and youth surveys to identify factors associated with the achievement and employment of students with and without disabilities. For students with disabilities, the significant achievement predictors were…

The purpose of this study is to examine the effects of a false assumption regarding the motivation of examinees on test construction. Simulated data were generated using two models of item responses (the three-parameter logistic item response model alone and in combination with Wise's examinee persistence model) and were calibrated using a…

Adopting a person-centered approach, we profiled 5th and 6th grade children's (152 boys and 161 girls) school-related beliefs about perceived task difficulty and agency beliefs in ability and effort. Five clusters were compared across key learning-related dimensions encompassing underlying worldviews (means--ends beliefs, normative difficulty,…

This article examined two item-writing guidelines: the format of the item stem and homogeneity of the answer set. Answering the call of Haladyna, Downing, and Rodriguez (2002) for empirical tests of item writing guidelines and extending the work of Smith and Smith (1988) on differential use of item characteristics, a mock multiple-choice driver's…

Active learning enhances engineering education. This paper presents rationale, curriculum supplements, and an approach to active learning that may be seamlessly incorporated into a traditional lecture-based engineering class. A framework of educational theory that structures the active learning experiences and includes consideration of learning…

This essay presents a case study of the modes used in training employees at a munitions plant in Ohio between 1940 and 1945. Theories of multimodal discourse and learning advanced by The New London Group (1996), Gunther Kress and Theo Van Leeuwen (2001) and Richard Mayer (2001) inform this analysis. With an unskilled labor force and many workers…

An assessment framework is like a blueprint, laying out the basic design of the assessment by describing the mathematics content that should be tested and the types of assessment questions that should be included. It also describes how the various design factors should be balanced across the assessment. This is an assessment framework, not a…

In a line of research employing a survey instrument, the "Critical Thinking Belief Appraisal", teachers supported critical-thinking (CT) activities more for high- than low-advantage learners, likely exacerbating a "rigor gap" implicated in persistent achievement gaps. Such beliefs were less likely to be espoused by expert teachers than randomly…

Animated models explicate the procedure to solve a problem, as well as the rationale behind this procedure. For abstract cognitive processes, animations might be beneficial, especially when a supportive pedagogical agent provides explanations. This article argues that animated models can be an effective instructional method, provided that they are…

This study examined the effects of task difficulty on on-task behavior for four students exhibiting low levels of math performance and on-task behavior. Curriculum-based assessments were conducted with each student to define the difficulty level of math tasks for each student based on the individual's rate of accurate performance on computational…

This study examined the cognitive levels of questions used by Iranian EFL teachers in advanced reading comprehension tests. Twenty teachers participated in this study and generated 215 questions which were then categorized according to Bloom's taxonomy. This taxonomy consists of six major categories which starts from the simplest behavior to the…

This paper reports on the findings from a quantitative research study into the use of a software tool that was built to support a part-complete solution method (PCSM) for the learning of computer programming. The use of part-complete solutions to programming problems is one of the methods that can be used to reduce the cognitive load that students…
