The cognitive determinants of number series completion performance were studied by presenting a systematic set of problems to college adults and to average- and high-IQ elementary school children. In each group, a combination of process and content-knowledge variables accounted for more than 70 percent of the variance in solution difficulty.…

Parts 1 and 2 (SE 524 424 and 527 089) described Flesch readability for determining a text's reading level and results of applying the test to astronomy/physics textbooks. This part presents results for a new sample of texts, including calculus-level texts. A comparison with high school physics texts is provided. (JM)

The problems that educational philosophers face in communicating with: (1) school of education faculty; (2) specialists in other areas of philosophy; and (3) educators and laymen involved in the schools are discussed. Four levels of discourse are proposed; the importance of tailoring abstraction level to audience needs is stressed. (PP)

The hierarchical structure of the cognitive domain presented in Benjamin S. Bloom's taxonomy of educational objectives does not reflect the actual nature of the learning process. Attempts to apply the classification levels to student learning in mathematics and other subjects place the taxonomy's usefulness in question. (PP)

The present findings imply that a readability formula is not an effective writing production criterion, even when the writer does not deliberately write to the formula. Comprehensibility of text might be better controlled through the proper use of the transformer concept (MacDonald-Ross and Waller). (Author/PN)

The success of distance teaching depends largely on students' comprehension and appreciation of print communication. A communication gap exists, and many students are unable to recognize levels of complexity presented to them. Changes in course structure can help alleviate this learning problem. (MSE)

The effects of a modified mastery learning system on achievement in an individualized high school physical science course are examined. Results indicate that a medium performance standard was superior to both high and low standards for promoting achievement in both difficult and easily learned materials. (JN)

Designed to determine whether (1) children of middle socioeconomic status (SES) learn matrix completion rules more rapidly than lower-SES children; (2) feedback influences rate of rule acquisition; (3) rule shifting influences rate of rule acquisition; (4) SES is associated with transfer of training; and (5) effectiveness of rule acquisition and…

Using information contained in nine photographs, young children constructed a wooden pyramid. Control children were given the same task but no pictorial information. Children's performances were significantly better when pictorial information was available. Sex and age differences were noted regarding strategies used to complete the task.…

The item bank (Rasch model) has serious limitations for the national assessment of subject performance: it requires agreement about the scope and organization of each school subject and about the difficulty level of each test item; and items tend to focus on factual knowledge, ignoring other desirable learning outcomes. (SJL)

Faced with a problem in which the probability of obtaining the correct answer was 70 percent, 2 of 23 kindergartners and 18 of 19 second graders generated an appropriate strategy. When the probability of a chance correct response was reduced to .45, 23 of 35 kindergartners generated an appropriate strategy. (Author/GDC)

In the first drill, the branching type, subjects received problems matched to their ability. In the second drill, the fixed type, subjects received problems from all difficulty levels. Performance on both the pretest and posttest indicated that the fixed drill yielded the highest gains for more difficult problems. (Author/CP)

Two procedures are presented for detecting violations of the unidimensionality assumption made by latent trait models without requiring factor analysis of inter-item correlation matrices. Both procedures require that departures from unidimensionality be hypothesized beforehand. This is usually possible in achievement tests where several content…

Examines the relationship between syntactic complexity and quality ratings of narrative and argumentative writing of students in grades 6, 10, and 12. (HOD)

An attempt is made to establish a link between ordinary arithmetical situations and relevant mathematical concepts by the analyzing of complexity of concepts. (MP)
