Using 45 undergraduate evaluations of videotaped lectures, this study examined the effects of the purposes of rating on measures of accuracy in observing teacher behavior and in evaluating teacher performance. Results suggest that the purpose affects the way raters process behavioral information without necessarily affecting the general level of…

Using a microcomputer "dart" game, this study of 61 primary school students investigated how children of different ages used counting to make numerical estimates. Results showed developmental differences in accuracy of estimation, fluency in counting and sophistication of self-reported strategy use. (BS)

The effects of four major types of expository text on the comprehension performance of 69 third and 69 sixth graders were investigated. Results suggest that knowledge of discourse types underlies effective expository comprehension and that this ability increases as children reach the upper elementary grades. (BS)

A standardized open-ended interview was used to study how children, four to eight years of age, judge their own and their classmates' abilities. Self-ratings declined with grade, but peer ratings did not. Evaluation differences are discussed in terms of cognitive development and changes in the educational environment. (BS)

Meta analysis was used on 18 studies of elementary students that tested the effects of teacher expectation on pupil IQ. Data supported the view that the better teachers know their pupils at the time of expectancy induction, the smaller the treatment effect. Additional findings and implications for further research are discussed. (BS)

In this study on the interactive effects of advance organizers and reasoning skills, 112 undergraduates read a literature text preceded by either a comparative advance organizer or a placebo introduction. Results suggest that instructional organizers produce neither serious loss nor substantial benefits for many purposes of communication. (BS)

Using 198 college students, this study investigated the effects on performance of four variables in a concept-learning task. The variables were (1) passive and active learning; (2) contextual specificity and variability; (3) rule-examples sequences; and (4) near and far transfers as critical outcomes. Results are discussed in terms of the…

Forty-six junior high students were administered six tests after a variety of instructional units using PLATO and classroom instruction. Twenty-seven procedural errors in signed-number arithmetic problems were classified into two groups to facilitate investigating error changes at different times and designing remedial instruction. (BS)

Using 146 high school students, this research assessed the effects of aptitude, strategy training, and item characteristics on the strategic processes employed in the performance of spatial visualization tasks. Treatment effects were shown to depend on the subject's aptitude profile and on the characteristics of items. (BS)

Six studies were reported questioning the conclusions of Covington and Omelich that pride in success, shame in failure, and positive self-esteem are more closely linked with ability ascriptions than with effort. The research demonstrated that affective intensity is in part determined by the perceived importance of the task. (BS)

This rejoinder to Brown and Weiner (TM 509 074) attempts to resolve areas of apparent conflict and to offer a broad synthesis around the self-worth theory of achievement motivation. The different yet compatible aspects of attribution and self-worth theories in regards to achievement effort are discussed. (BS)

In response to Covington and Omelich (TM 509 075) four main empirical points of agreement regarding achievement strivings are summarized. Four issues concerning the interrelationship of effort and ability attributions and self-worth that need theoretical and empirical resolution are discussed. (BS)

The results of synthesizing 40 studies regarding the effects of gender characteristics of instructional materials on students indicate that sex-equitable materials can improve both male and female students' learning experiences and assist in developing gender-balanced associations and more flexible sex role attitudes. Effects on preference and…

Using data from the Survey of Basic Skills administered to approximately 300,000 California sixth graders, this study examines sex differences on two types of mathematics items. Probability for success is greater for girls in solving computations and for boys in solving story problems. Relationships to other influential factors are examined.

This study added extraneous information and increased syntactical complexity to determine the relative importance of computational and reading abilities in solving arithmetic word problems. Analyzing tests of 200 sixth graders indicated the combined abilities accounted for 54 percent of the variance in solution accuracy. (BS)
