An elementary survey of item characteristic curve theory, centered around the problems of individualized (tailored) testing, is presented. Following the introduction, discussions are provided of the following: Test Theory for Itemized Tests; The Guttman Scale; Item Characteristic Curve Theory; An Alternative Model; Specialization, Application, and…

Under Part C of the Individuals with Disabilities Education Act (IDEA), participating states and jurisdictions must provide services to children who are either experiencing developmental delays, or who have a diagnosed mental or physical condition that has a high probability of resulting in developmental delay. Additionally, states may choose to…

Presents activities taken from the National Council of Teachers of Mathematics Addendum Series, grades 5-8, involving data collection and chance. Students determine whether a game is fair based on the data collected and examine rule changes to ensure fairness. (MDH)

Development of an inexpensive but powerful computer program to teach clinical periodontal diagnosis using epidemiological principles is described. Using probabilistic thinking, the student is guided from application of raw research data to derivation of likelihood ratios and how they affect clinical decision making. Student response was found to…

Presents four primary objectives for written assignments. Describes the use of writing assignments in a college probability and statistics course. Maintains that this approach requires students to show statistical and writing skills rarely elicited elsewhere in their coursework. (CFR)

Effects of altering test difficulty on examinee ability measures and test length in a computer adaptive test were studied for 225 medical technology students in 3 test difficulty conditions. Results suggest that, with an item pool of sufficient depth and breadth, acceptable targeting to test difficulty is possible. (SLD)

Discusses area models that can be used in grades three through nine, showing how the model generalizes from discrete situations involving the arithmetic of whole numbers to continuous situations involving decimals, fractions, percents, probability, algebra, and more advanced mathematics. (14 references) (MDH)

This study examines the characteristics and quality of simplification in graded readers as compared to those of "normal" authentic English. Two passages from graded readers are compared with the original passages. The comparison uses a computer programme, RANGE (Nation and Heatley, 2003) to analyse the distribution of high and low frequency words…

This article reports on a study of obstacles to employment among mothers with children in foster care. The study relies on standardized measures, has a cross-sectional design, and includes a sample of 158 mothers. The analysis shows a high prevalence of obstacles; identifies three co-occurring obstacles, each involving substance abuse, that are…

In this study, the authors investigated the role of overconfidence on students' performance on multiple-choice examinations. The authors examined the difference between students' self-assessed probability of selecting each correct answer and the proportion of correct answers that they actually selected. Results show that high-performing students…

The sport of Ultimate has grown from parking lot fun to international competition in its 35 year existence. As in many sports, the team that scores is subsequently on defense. Thus the probability that a team will score next is dependent on which team has scored most recently. Unlike in many other sports, teams switch ends after each score. Thus…

This paper presents findings from a study of the experiences and outcomes of older and younger community college students. We developed a discrete-time hazard model using longitudinal transcript data on a cohort of first-time community college students in Florida to compare the impact of enrollment pathways (such as remediation) and enrollment…

Recent research indicates that college students who transfer from community colleges are significantly less likely to complete a 4-year college degree than students who begin at 4-year institutions. This paper estimates models of college completion for both types of students. Based on these results, an Oaxaca decomposition indicates that students…

This document compiles an "honest list" of what is needed for adult numeracy. The first section consolidates the four posited Massachusetts Adult Basic Education (ABE) Math Standards into three adult numeracy themes: relevance/connections, problem solving/reasoning/decision making, and communication. A discussion of each theme is followed by some…

The Probability Inquiry Environment (PIE) is being designed as a computer-mediated collaborative inquiry environment to aid middle school students in learning elementary probability. This paper reports on a study in which seventh grade students engaged in probabilistic reasoning while interacting with a preliminary version of PIE. By analyzing the…
