The general feeling is that no predictions can be made based on agent-based social simulations. The outcomes of social simulations are based on the behaviors of individuals and their interactions. Behavioral models are always incomplete and often, also incorrect with respect to real behavior and thus the outcomes of agent-based social simulations…

The Additive Factor Model (AFM) is a cognitive diagnostic model that can be used to predict student performance on items in a context that allows for student learning. Within AFM, "skills" have a learning rate, and student acquisition of a skill depends only on the number of opportunities a student has had to exercise that skill and the…

Students in the United States whose household income is less than 130% of the poverty line qualify for free lunch, and students whose household income is between 130% and 185% of the poverty line qualify for reduced-price lunch. Education researchers and policymakers often use free and reduced-price lunch (FRPL) status to measure socioeconomic…

Recently, Northwest Evaluation Association (NWEA) completed a study to connect the scale of the Minnesota Comprehensive Assessments (MCA) Testing Program used for Minnesota's mathematics and reading assessments with NWEA's RIT (Rasch Unit) scale. Information from the state assessments was used in a study to establish performance-level scores on…

Gargani and Strong claim to have developed and validated an observation system that requires only 4 hr of training, but one that can identify effective teachers using just 20 min of one video-taped lesson. They further contend that their six-item inventory requires little judgment from those who use it. They describe their instrument, the Rapid…

For years, colleges have used placement exams to determine whether to deem incoming students "college ready" or assign them to developmental education. Emerging information reveals the tests have little correlation to students' future success, casting doubt on their use even as the high stakes for students of taking remedial courses become clear.…

This report analyzes the psychometric properties of the revised school-level SEL implementation rubric and the SEL specialists' activity log.

Graduate studies, and in particular doctoral ones, pursue the development of scientific researchers able to make original contributions in a specific area of knowledge. However, attrition rates indicate that achieving this goal is not easy. The available evidence indicates that there are behavioral factors, positive and negative, that influence…

Community colleges are typically assumed to be nonselective, open-access institutions. Yet access to college-level courses at such institutions is far from guaranteed: the vast majority of two-year institutions administer high-stakes exams to entering students that determine their placement into either college-level or remedial education. Despite…

Recently, the Northwest Evaluation Association (NWEA) completed a study to connect the scale of the North Carolina State End of Grade (EOG) Testing Program used for North Carolina's mathematics and reading assessments with NWEA's Rausch Interval Unit (RIT) scale. Information from the state assessments was used in a study to establish…

This study reports on the validation of the language domain subtest of a developmental assessment scale for Cantonese Chinese preschool children. Three hundred and seventy eight multi-stage randomly selected children between 3;4 and 6;3 years of age were tested on the 104-item subtest. Fifty-four of these children, spreading across three age…

Seventeen state-sponsored residential math and science schools have been created across the country to direct talented teens toward STEM careers. Admission is selective, based on competitive grades, standardized test scores, and references. Most of the schools also require preadmission interviews. However, selection interviews may be challenged as…

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…

A valid and reliable instrument for measuring affect intensity does not exist for adolescents; such a measure may help to refine understanding of emotion among youths. The purpose of the current study was to evaluate the psychometric properties and clinical relevance of a measure of affect intensity adapted for youths. Two hundred five community…

Analysis of children's spoken narratives represents a potentially informative approach to language assessment within early childhood settings. Yet, narrative assessment is not readily amenable to at-scale use given the time needed to collect, transcribe, and analyze a child's narrative sample and the lack of consensus regarding what aspects of…
