Explaining sex-related differences in mathematics: Theoretical models

This set of papers synthesizes contemporary psychological research to identify and operationally specify major influences on abilities, interests, and skills in mathematics. Three models are then presented which hypothesize causation of the sex-related differences in mathematics that exist: (1) a four-factor model which explores mediating factors of autonomous learning behaviors which exist between socialization influences and learning; (2) a detailed socialization model of election of mathematics courses; and (3) a model of internal barriers which prevent females from fully developing mathematical skills. The models all suggest that causation of sex-related differences in mathematics are complex and multivariate. Social conditions affect the educational environment of a female as well as the personal belief system of each learner. Directions for research built on these models are indicated.     

A comparison of sentence-learning errors in children of different achievement levels

Theoretical analyses of the multiple-choice test format suggest that a test constructor should give serious consideration to the form in which correct and incorrect alternatives are presented. In this experiment, third and fourth graders were tested for previously exposed information by multiple-choice items in which: (a) correct alternatives were stated in either verbatim or synonym form; and (b) incorrect alternatives consisted of plausible responses that were either familiar or new. Comparisons of errors and error patterns were made between high and low achieving students who had been given one of two different information-processing strategies. Based on a dual test function argument, it was concluded that synonym correct alternatives combined with plausible new responses are the most desirable of the four multiple-choice variations studied here. In particular, such items were sensitive to achievement level and strategy differences without systematically increasing students' likelihood of retaining misinformation.     

“Look,a [picture]!”: Visuality,race, and what we do not see

This article argues that understanding vision and visuality as associated but distinct terms has significant implications for the ways in which we engage with racial constructions of identity. Expanding the ways in which we visualize race beyond simply the visual offers us a more comprehensive approach to understanding the construction of and response to race in the twenty-first-century United States. This article moves from theoretical implications of non-visual visualizations like tactile visuality and audial visuality through photographs taken by blind photographers to ask how race and racial identity are implicated in conversations about both vision and visuality.     

Relative effectiveness of reading practice or word-level instruction in supplemental tutoring: how text matters

In this quasi-experimental study, which is part of a series of investigations on supplemental reading tutoring variations, the relative effectiveness of more intense decoding instruction or text reading practice was examined. Fifty-seven first-grade students scoring in the lowest quartile for reading skills received either classroom reading instruction or one of two treatments: tutoring in word study with text reading practice, or word study tutoring alone. Individual instruction was provided by trained paraprofessional tutors. At the end of first grade, treatment students significantly outperformed their nontutored peers on measures of reading accuracy, reading comprehension, reading efficiency, passage reading fluency, and spelling. Differential treatment effects on passage reading fluency are examined, taking into consideration pretest skill levels and text reading practice characteristics.     

The effects of strong irrelevant thirst on food-rewarded instrumental performance

In Experiment I, rats received one food rewarded trial per day in a runway. One group received all its trials under hunger (Group H); the second group received a random half of its trials under hunger and the other half of its trials under hunger plus thirst (Group H-HT). Group H-HT ultimately ran slower on HT trials than on H trials. In Experiment II, the effects of shifting from H to HT and vice versa were examined in a five-phase design. In general, rats run under H ran faster than rats run under HT, and shifts from H to HT produced rapid decreases in speed, while shifts from HT to H produced extremely slow increases in speed. The results of both experiments were interpreted as indicating that the reward value of food is greater under H than under HT and that the manipulation H vs. HT may be viewed as theoretically similar to manipulation of reward magnitude.
