A detailed analysis and computer-based solution to a puzzle addressing the arrangement of dominoes on a grid is presented. The problem is one used in a college-level data structures or algorithms course. The solution uses backtracking to generate all possible answers. Details of the use of backtracking and techniques for mapping abstract problems…

Examines the use of tasks with backward false belief explanation as an effective technique in gaining a complete picture of the development of understanding of the representational mind. Argues that traditional prediction tests of false belief cannot tell whether children's wrong answers show misunderstanding about false belief or seduction by the…

An optimal unbiased classification rule is proposed based on a longitudinal model for the measurement of change in ability. In general, the rule predicts future level of knowledge by using information about level of knowledge at entrance, its rate of growth, and the amount of within-individual variation. (SLD)

Investigated rates of birth, divorce, marriage, and unemployment for subgroups in Canada and the United States and their effects on suicide rates. In Canada, domestic integration and the economy predicted youth suicide rates more accurately than they did adult rates. The United States had less variation in predictors for age groups. (RJM)

This commentary on a paper by Douglas Detterman and others (EC 604 995), which tested a model assessing basic cognitive abilities in young adults with and without mental retardation, criticizes the paper for drawing conclusions not justified by the empirical results. (JDD)

A modified Conflict Tactics Scale and the Child Abuse Potential (CAP) Inventory were administered to three groups. The CAP abuse scores distinguished among physically abusive mothers with a childhood history of abuse and nonabusive mothers with and without a childhood history of abuse. Intergroup differences were exhibited in rigidity and…

Use of 11 kinds of visual aids by 458 clients of an Israel low vision clinic was evaluated by age, sex, work status, participation in a rehabilitation program, academic status, number of visual aids in use, and number of diagnosed eye diseases. Usage prediction was found to be complex and highly differentiated. (Author/JDD)

The relationship between early otitis media with effusion (OME) and later language development was examined in a prospective cohort of 30 children from middle class families and 33 children from low income families. Findings suggested no reliable relationship between early OME experience and later language development. (Author/DB)

In three task settings differing in difficulty and turnover rate in a truck assembly plant, structured on-the-job training (OJT) provided twice the financial benefits as unstructured OJT and required one-fifth the mastery time. Turnover rate had a greater effect on benefit size than did task difficulty. (SK)

The authors describe a simple forecasting strategy that focuses on environmental and global topics. Students choose their own topics, collect and analyze data, make predictions, and present findings to the class. Authors claim the following advantages of forecasting: students become motivated; work in cooperative groups; increase skills in…

Examines previous studies of the effects of prediction activities, prior knowledge, and text type upon reading comprehension. Finds the three elements unimportant to ordinary reading. Observes that many schema theory concepts arose from analysis of difficult reading. Suggests that the schema theory variables may arise only in atypical reading…

The residential independence of students with disabilities who had exited high school was assessed, using data from 2,686 interviewees in the National Longitudinal Transition Study. Individual characteristics, such as intelligence, living skills, and bad conduct records, were better predictors of postschool living arrangement status than were…

This study examined whether stress, family resources, and social support are correlates of the child abuse potential of mothers. Stress in family functioning appeared to be an important predictor of child abuse potential. Mothers of children with disabilities may be more inclined than other mothers to have elevated child abuse potential.…

Improvements are made on previous estimates for the conditional standard error of measurement in prediction, the conditional standard error of estimation (CSEE), and the conditional standard error of prediction (CSEP). Better estimates of how test length affects CSEE and CSEP are derived. (SLD)

The general structure of the human resource planning function in organizations and the responsibilities at each level of management are discussed. A framework for constructing and implementing a human resource planning system is outlined, and several approaches for human resource forecasting are examined. (MSE)
