This paper has two purposes: (1) to describe the general characteristics of a research project on which this is one part; and (2) to report an experimental attempt at improving academi c performance of low achieving ninth grade students through self concept enhancement (Experiment B). Briefly discussed are the experiments and the research design…

Using 40 male and 40 female part time learners with an average age of 36.6, this program planning study explored relationships between selected learner characteristics and behaviorally stated cognitive instructional objectives (IOs). Variables included age, sex, socioeconomic status, verbal ability, and a measure of learners' goals or learning…

Instructional cross-media experiments are difficult to design because they involve complex instructional systems which include variables that are hard to control. Strict controls can be approached in the laboratory setting, but as the experimenter moves from the laboratory to the field study, especially in developing countries, concessions to…

The purpose of this paper is twofold: (1) to indicate some of the major weaknesses in the design and approaches to compensatory education programs, and (2) to recommend a more appropriate evaluational design. The second purpose deals specifically with a recommended evaluational procedure; i.e., the discussion centers around an account of what…

A Bayesian prediction strategy is outlined in which antecedent measures are divided into two subgroups. One subgroup is used to discriminate among criterion groups, the second to provide normal linear predictions for each group. Individualized regression constants are subsequently obtained by computing probabilities of group membership from the…

This progress report on the Family Development Research Program for 108 low-income families, conducted at Syracuse University Children's Center, provides information on a longitudinal comparison instituted when the program children reached 36 months of age. The families of the children were matched to control families on a number of variables.…

A study was conducted to examine two methods of presentation of social studies questions used in teaching selected concepts to second-grade children and to determine which method was more effective as reflected in the achievement demonstrated by the subjects. The procedure used was a 3x2x2 (Treatment by Sex by School Location) fixed-effects…

Investigations designed to eliminate ambiguities in the Andre and Kulhavy procedure and to investigate the effects of noun modifications and sentence voice in the category clustering of sentences were conducted. Two experiments were carried out; both employed a mixed factorial design and were prepared in dittoed booklets. The Ss were run in…

Infants judged to be at risk for subnormal intellectual growth were randomly assigned to experimental and control groups which varied as to educational curriculum activities. Two types of evidence, group differences and parent-child IQ correlations, demonstrate the importance of early environments in intellectual development. (Author/RD)

Investigates the interaction between the presence or absence of explicit instruction and the variables complexity and morphology/syntax in the acquisition of four second language (L2) structures. Results from computer-controlled posttests confirm the hypothesis that explicit instruction facilitates the acquisition of L2 grammar. (66 references)…

Indicates that utilizing calculators to introduce algebraic concepts in a prealgebra course provides students with a solid foundation for the study of college mathematics. Pedagogical criteria emphasized the difference between exact and approximate results, appropriate use of the calculator in problem solving, the role of estimation in…

In two studies, children's memory of venipuncture or inoculations were compared with memory of less stressful events. In another study, natural variations in children's stress and the effect of short delays were examined. In yet another study, a delay interval of one year was examined. (BB)

To examine the influence of friends on school achievement motivation, each of 118 eighth graders was paired with a close friend to discuss dilemmas concerning achievement motivation or an unrelated topic. Friends' decisions on motivational dilemmas were more similar after discussion than before. Discussions did not cause more extreme decisions.…

The role of elaborative interrogation in children's learning of facts was investigated in 2 experiments involving 211 female and 185 male Canadian fourth through eighth graders. When compared to the facts alone, precise elaborations given by the experimenter, or learner-constructed imagery, elaborative interrogation produced better learning in…

This commentary on EC 605 442, which indicated long-term gains for children with autism who experienced intensive behavioral intervention as preschoolers, questions the magnitude of the student changes and their significance, because of concerns about the representativeness and comparability of the sample group and the failure to measure skills…
