Presents a problem for students in grades 1-6 concerning the concept of probability. Discusses the student problem-solving process, and provides some responses to the problem published in the January 1998 issue of this journal. (ASK)

Illustrates how the Academy Awards can provide an excellent motivational tool in teaching probability and statistics and presents related activities. (ASK)

Describes ways of thinking about probability and some common student misconceptions. Suggests ways of addressing students' misconceptions and illustrates these ideas with an example. (ASK)

Proves price index (proportion of references within the last five years of literature) is not a pure function of the mean or median reference age, but a well-defined relation in the form of a typical cloud of points. Compares models for analyzing price index (decreasing exponential and lognormal aging) and explains cloud using results from…

Creates graphs to see how the relative frequency of an event tends to approach the probability of that event as the number of trials increases. Uses a simulation of a poker machine to provide context for this subject. (ASK)

Describes and analyzes a learning episode in which two children in year 4 interact with each other and their teacher while playing a probability game involving chocolate M&Ms. Children developed key ideas in probability from a game that was designed to produce cognitive conflict. (ASK)

Presents a problem that has been well received by students in undergraduate mathematical statistics courses. The problem is presented as a game in which students are asked to choose between two alternatives, as if they were betting. (ASK)

Presents an activity in which students develop a handy strategy for exploring probability as applied in the life sciences by learning to use the Punnett square, an effective tool that helps students visualize sample spaces and determine the likelihood of events. (ASK)

Observes the application of probability theory to a game between two players. Shows how basic techniques such as tree diagrams can be used to demonstrate optimum strategies, how the art of bluffing can be quantified, and how this might be applied to a game of poker. (Author/ASK)

Investigates whether state course graduation requirements affect high-school dropout decisions, using aggregate data on dropout rates, individual data from two time periods, and aggregate data on high-school completion rates over 15 years. Results strongly suggest that state-mandated minimum course requirements cause students to drop out.…

Objective: According to mandatory reporting laws for professionals, the relationship between initial recognition that a child may have been abused and the subsequent reporting of that suspected case of child abuse to the responsible agency would, at first glance, appear to be clear. However, this relationship has developed into one of the major…

We conducted functional analyses and identified reinforcers for problem behavior for three individuals with developmental disabilities. Based on results of the functional analysis, we evaluated the rate, probability, delay, and duration of reinforcement for problem and appropriate behavior during descriptive parent-child observations. Results…

The authors examine the relationship between students' locus of control and their evaluation of teaching in a traditional principles of economics course. Locus of control is a psychological construct that identifies an individual's beliefs about the degree of personal control that can be exercised over his or her environment. Students with an…

This study attempts to improve our understanding of the prevalence and determinants of violent death in rural Bangladesh. Data came from a demographic surveillance system covering a population of nearly 62,000 in 10 districts of the country. Findings reveal that drowning and homicide were the leading causes of death followed by traffic accident…

Using American Citizen Participation Survey data (Verba et al. 1995a), we perform logistic regression analyses to adjudicate between three core explanations for individual protest: biographical availability, political engagement and structural availability. We calculate estimated probabilities to weigh the relative effects of these factors on the…
