The article compares three different methods to estimate effects of task characteristics and to use these estimates for model-based proficiency scaling: prediction of item difficulties from the Rasch model, the linear logistic test model (LLTM), and an LLTM including random item effects (LLTM+e). The methods are applied to empirical data from a…

Item Response Theory (IRT) models were applied to investigate the psychometric properties of the Arthur and Day's Advanced Progressive Matrices-Short Form (APM-SF; 1994) [Arthur and Day (1994). "Development of a short form for the Raven Advanced Progressive Matrices test." "Educational and Psychological Measurement, 54," 395-403] in order to test…

This article addresses an important, yet often underattended to, aspect of the strategy development process: fostering the use of strategic learning practices in the simultaneous practice of developing strategy and cultivating strategic mindset awareness. The need for addressing this aspect of the strategy development process is increasingly…

While many factors play into college student success, interaction with faculty has been identified as a key component. In highly challenging and anxiety-provoking courses, the student-faculty relationship may be all the more important. This study uses organic chemistry as a case example to investigate the role of the student-faculty relationship…

Text comprehension models in first and second language reading research posit that slow word recognition inhibits reading speed and decreases comprehension. To investigate the role of word recognition in reading, 2 experiments examined rereading benefits in participants' first and second languages using scrambled and normal versions of English and…

There is a large body of research indicating that L2 learners often have trouble with the word form. Learners often transfer their L1 processing routines over to the L2 in their attempt to process the L2 forms, whether those routines are appropriate to the L2 form system or not. This study explores the problems of learning L2 vocabulary word form…

In school, at least in the US, we were taught to multiply by hand according to a standard algorithm. Most people find that algorithm difficult to use, and many children fail to learn it. We propose a new way to make sense of this difficulty: to treat explicit computation as perceptually supported physical and mental action. Based on recent work in…

When using modern educational technology, some forms of instruction are inherently transient in that previous information usually disappears to be replaced by current information. Instructional animations and spoken text provide examples. The effects of transience due to the use of animation-based instructions (Experiment 1) and spoken information…

The focus of this paper is on the assessment of the two main processes that children must acquire at the single word reading level: word recognition (lexical) and decoding (nonlexical) skills. Guided by the framework of the dual route model, this study aimed to (1) investigate the impact of item characteristics on test performance, and (2)…

Texts are routinely simplified to make them more comprehensible for second language learners. However, the effects of simplification upon the linguistic features of texts remain largely unexplored. Here we examine the effects of one type of text simplification: intuitive text simplification. We use the computational tool, Coh-Metrix, to examine…

The Open Educational Resources (OER) movement was started roughly ten years old (Wiley & Gurell, 2009). Since that time thousands of resources have been produced. Though these resources have been used both for classroom development and for the autodidact, the development of OER was not without problems. Incompatibility between Creative Commons…

The authors investigated whether some advantages of tutoring over other instructional methods are due to microadaptation, or, tutors basing their actions on assessments of tutees they develop during tutoring. In a 2 × 2 between-subjects experiment, independent variables were shared experience (tutors either worked with the same or a different…

Background: Context-based learning approaches are used to enhance students' interest in, and knowledge about, science. According to different empirical studies, students' interest is improved by applying these more non-conventional approaches, while effects on learning outcomes are less coherent. Hence, further insights are needed into the…

Today's economy demands that "all" young people develop high-level literacy, quantitative reasoning, problem solving, communication and collaboration skills, all grounded in a rigorous, content-rich K-12 curriculum. Acquiring this knowledge and these skills ensures that high school graduates are academically prepared to pursue the…

A substantial literature documents the benefits of early childhood education and formal preschool experiences on children's school readiness, with low-income and otherwise disadvantaged children benefitting the most from these programs. However, these academic benefits often fade out as children age, and most disappear by the end of kindergarten…
