Technology rich learning environments provide the potential for engaging, relevant, and personalized curricula that prepare students for 21st century careers. However, a lack of strategic planning by educators results in available technology not being used to its fullest potential. Several educational organizations have published guidelines for…

Discussions of the barriers to completion in community colleges have largely focused on student success in introductory college-level math and English courses, and rightfully so, since these courses are typically required for degrees. However, there is a much broader range of courses that also serve as "gatekeepers" in the sense that they are…

This study investigated how task complexity affected native and non-native speakers' speaking performance in terms of a measure of communicative success (functional adequacy), three types of fluency (breakdown fluency, speed fluency, and repair fluency), and lexical diversity. Participants (208 non-native and 59 native speakers of Dutch) carried…

Despite a large increase in the number of students enrolled in online courses, published research on student experiences in these environments is minimal. This article reports the narrative analysis of a series of interviews conducted with a female student at a brick-and-mortar school enrolled in a single virtual school course. Her narratives…

This qualitative content analysis was conducted to determine how Mexico and Mexican people are portrayed in contemporary U.S. elementary social studies textbooks. Three textbooks from each of three major publishers were analyzed. Findings are presented in five sections: images and photographs, holidays, Mexican people and heroes, contested…

In operational equating, frequency estimation (FE) equipercentile equating is often excluded from consideration when the old and new groups have a large ability difference. This convention may, in some instances, cause the exclusion of one competitive equating method from the set of methods under consideration. In this report, we study the…

In this paper, we present a study of a large corpus of student logic exercises in which we explore the relationship between two distinct measures of difficulty: the proportion of students whose initial attempt at a given natural language to first-order logic translation is incorrect, and the average number of attempts that are required in order to…

While autism is one of the most intensively researched psychiatric disorders, little is known about reasoning skills of people with autism. The focus of this study was on defeasible inferences, that is inferences that can be revised in the light of new information. We used a behavioral task to investigate (a) conditional reasoning and (b) the…

Despite the fact that rigor is generally advocated for gifted learners, how it should be measured is not well defined. This lack of specificity in defining academic rigor often makes it difficult to determine if curriculum for gifted learners met their learning needs. With this need in mind and in response to the challenge of the North Carolina…

Biological rhythms play a prominent role in the modulation of human physiology and behavior. [Smith, K., Valentino, D., & Arruda, J. (2003). "Rhythmic oscillations in the performance of a sustained attention task." "Journal of Clinical and Experimental Neuropsychology," 25, 561-570] suggested that sustained human performance may systematically…

History teachers are faced with an impossible dilemma. Voices from every corner urge them to use primary sources. Sources, teachers are told, are to history what the laboratory is to science: the place where the subject becomes most vital. At the same time, any teacher who has used sources knows the many obstacles. Using sources to make history…

A computer programming class for students of mechanical engineering was redesigned and assessed: Cognitive Load Theory was used to redesign the content; online technologies were used to redesign the delivery. Student learning improved and the dropout rate was reduced. This article reports on both attitudinal and objective assessment: comparing…

The authors clarify the source of a conflict between previous findings related to metacognitive control over the distribution of practice. In a study by L. Son (2004), learners were initially presented pairs of Graduate Record Examination (GRE) vocabulary words and their common synonyms for 1 s, after which they chose to study the pair again…

Expectations about self-competence and difficulty of a task to be undertaken can foster motivation and hence affect engagement, giving rise to individual differences in performance. This effect was examined in a memory task. An increase in recall performance following instructions about high competence was hypothesised; in addition, a modulating…

It is known that the Rasch model is a special two-level hierarchical generalized linear model (HGLM). This article demonstrates that the many-faceted Rasch model (MFRM) is also a special case of the two-level HGLM, with a random intercept representing examinee ability on a test, and fixed effects for the test items, judges, and possibly other…
