The purpose of the present study is to examine the language characteristics of a few states' large-scale assessments of mathematics and science and investigate whether the language demands of the items are associated with the degree of differential item functioning (DIF) for English language learner (ELL) students. A total of 542 items from 11…

Purpose: The purpose of this paper is to consider how simulations are increasingly used in training programs for the development of skills such as leadership. However, the requirements of leadership development go beyond the development of task specific procedural knowledge or expertise that simulations have typically been used to develop.…

Training and investing teachers at all career levels in student-centered practices is widely recognized as a significant challenge. Various studies document the failure of student-centered teaching practices to take hold in K-12 mathematics classrooms in significant ways, including collaborative work; problems that are cognitively demanding or…

The present study examined two key aspects of young children's ability to explain human behaviour in a mentalistic way. First, we explored desires that are of a level of difficulty comparable with that of false beliefs. For this purpose, the so-called "alternative desires" were created. Second, we examined how children's psychological…

Boys identified as learning-disabled gifted or twice exceptional, at two different grade levels (5th or 6th grades, and 11th or 12th grades), were asked to read a history text with unknown vocabulary words, internal inconsistencies, and prior knowledge violations inserted to make immediate comprehension difficult. The students were asked to read…

We have designed, developed, and validated a 25-question Genetics Concept Assessment (GCA) to test achievement of nine broad learning goals in majors and nonmajors undergraduate genetics courses. Written in everyday language with minimal jargon, the GCA is intended for use as a pre- and posttest to measure student learning gains. The assessment…

This paper summarizes difficulties that chemistry students at all levels commonly exhibit when translating, manipulating, and interpreting mathematical expressions that contain logarithms, and offers approaches that the authors have found useful to help students overcome such difficulties. The online supplement provides problem sets created by the…

This case study involves investigation of freshman students' abilities to engage in the pursuit and appreciation of complex thinking through their study of comedy and laughter in a Freshman Seminar at the University of Wisconsin-Milwaukee. We offer an analysis of students' reflections on their confrontation with complexity as they attempt to…

Growing recognition of the central importance of fostering an in-depth understanding of natural selection has, surprisingly, failed to stimulate work on the development and rigorous evaluation of instruments that measure knowledge of it. We used three different methodological tools, the Conceptual Inventory of Natural Selection (CINS), a modified…

Each year, thousands of American students enter postsecondary institutions unprepared for college-level work and are subsequently placed in remedial or developmental courses. Several recent studies have examined the impact of these courses on student outcomes, but such studies focus exclusively on students who need just one or two classes; the…

Understanding the user and customizing the interface to augment cognition and usability are goals of human computer interaction research and design. Yet, little is known about the influence of individual visual-verbal information presentation preferences on visual navigation and screen element usage. If consistent differences in visual navigation…

After years of debate, the nation is now taking a bold step toward ensuring that all students graduate ready for college and careers. Under the leadership of the Council of Chief State School Officers and the National Governors Association Center for Best Practices, a panel has drafted a set of Common Core State Standards for college and career…

The purpose of the study is to present research focused on validating the four algebra cognitive models in Gierl, Wang, et al., using student response data collected with protocol analysis methods to evaluate the knowledge structures and processing skills used by a sample of SAT test takers.

We live in a climate ripe for noise: Media outlets and 24-hour news cycles mean that everyone with access to a computer has access to a megaphone to broadcast their views. Never before in human history has an opinion had the opportunity to reach so many so quickly regardless of its accuracy or appropriateness. Of course, it's difficult to hear…

To foster medical students' diagnostic knowledge a case-based worked example approach was implemented in the context of a computer-based learning environment. Thirty medical students were randomly assigned to the condition "with erroneous examples", and 31 students learned with correct examples. Diagnostic knowledge was operationalised…
