This study assessed the ability of fourth, fifth, and sixth graders and college students to logically include and exclude variables when making inferences about a multivariate "natural experiment" situation. (Author/SB)

Children, ages 6, 8, and 10, were exposed to three types of training procedures aimed at increasing their use of constraint-seeking questions and enhancing their problem-solving efficiency. Effects of the different procedures on each age group were examined. (JMB)

Explores the role of premature cognitive closure in the development of inferential reasoning among 62 children aged 7, 9, and 12 years through two studies. Results indicate that despite a strong tendency to close on single alternatives, most children correctly assigned nonzero probabilities to each of the possible alternatives. (RJC)

First-, third-, fifth-, and sixth-grade children were administered 20 relational reasoning problems in which they had to deduce the possible sizes of one item relative to two others on the basis of a visual comparison and a written clue. Dramatic differences were observed between fifth- and sixth-grade children. Corrective feedback improved…

Three experiments investigated effects of attentional factors on children's learning set performance. Younger children's learning was differentially affected by two or more irrelevant dimensions. Practice improved performance for all ages. Results confirmed that irrelevant dimensions and within-problems exposure interact with age and amount of…

The ordering of difficulty of logic principles and the age of acquisition for each were examined with 160 gifted children (20 each from ages 4 to 11). Five principles of class logic were explored: three orders of enthymemes, i.e., missing conclusion, missing minor premise, and missing major premise; and two additional third order enthymemes, i.e.,…

A significant multivariate difference was found between the oral language performance of 44 children labeled reading disabled in the second, fourth, and sixth grades and 59 normally reading children in the same grade. (Author/PHR)

Two studies involving five- and nine-year-old children examined the effects of planning with a partner as well as the relation of collaborative planning to subsequent solo planning. Results suggest that cognitive gains resulting from joint problem solving between children and adults or peers may be more likely with shared task responsibility. (RH)

Thirty-six children from grades 1, 3 and 6 observed and rewarded a peer who played an experimental game. Children experienced a developmental shift in the criteria they used to reward a peer's performance. References to intention-act matches increased with grade and with children's understanding of controllable and noncontrollable tasks and causal…

"Education at a Glance: OECD Indicators" is the authoritative source for accurate information on the state of education around the world. It provides data on the output of educational institutions; the impact of learning across countries; the financial and human resources invested in education; access, participation and progression in…

Deductive reasoning problems were presented to 72 public elementary school students, half of whom were identified as gifted (mean age of 9.6 years) and half of whom were regular education students (mean age of 9.3 years). They were used to test an hypothesis that gifted children who score significantly higher than average on standardized…

Two studies were conducted with 8- and 10-year-old children to examine sources of age and skill differences in verbal analogical reasoning. Discussion focuses on the child's "problem space" for the analogy task and possible differences in task understanding that lead to strategy and process differences in older versus younger and skilled versus…

Studied structures and relationships in one-step additive and multiplicative problems solved by 450 students in grades 2, 3, and 4. Results show that the facility ratio of the problems differs by structure, situation, and the sequence of data. The ability to solve one-step problems increases with age, but relative problem difficulty is grade…

Korean children's knowledge of appropriate self-regulated behaviors related to the solving of school-based or nonschool-based programs was studied. An attempt was made to determine the grade level (kindergarten, first, third, and fifth) differences in perceptions of appropriate problem-solving behaviors from the perspective of self-regulation…

This research investigated developmental shifts in the character of children's tool using activity in the domain of scale drawing. Fifty-five children from three grade levels (grades 3, 5, and 7) were individually interviewed as they participated in both enlarging and reducing a one-dimensional object, the letter "F," to a scale of four.…
