Reinforcement techniques for increasing the attention span of retarded students is investigated. (CD)

The premise that mental age is not a valid standard by itself for educational placement was explored. (CD)

The approach presented for teaching the mentally handicapped is an adaptation of Frank Hewett's engineered classroom concept. (CD)

The article discusses behavior modification techniques designed to prepare the child for integration into the regular class setting. (CD)

The performance of students from three intelligence levels at grades 4, 5, 6, and 7 on certain discovery tasks in arithmetics are examined. Results indicate that students should be given from 3 to 6 instances to make discoveries of the type tested and that students of lower intelligence levels can form generalizations. (FL)

A study designed to investigate a method examining some of the processes involved in students' forming of mathematical concepts in an experimental mathematics course. Results suggest that the card sorting task offers a useful tool for use in evaluation programs. (FL)

This study investigated the relationship between conservation of length and impulsive-reflectivity. Kindergarten and first-grade students were administered two conservation of length tasks and an impulsive-reflexive scale. No statistically significant relationship between the two concepts was found. (FL)

Examined were differential performances among categories of first graders when solving arithmetical workd problems of eight types under two distinct conditions. The categories were based on various types of quantitative comparisons which children are known to make. Several statistically significant results were obtained involving differences…
