Effect of science teaching on the young child's concept of piagetian physical causality: Animism and dynamism

The purpose of this research was to determine whether the young child's understanding of physical causality is affected by school science instruction. Sixty-four subjects, four and one-half through seven years of age, received 300 min of instruction designed to affect the subject's conception of causality as reflected in animism and dynamism. Instruction took place for 30 min per day on ten successive school days. Pretesting was done to allow a stratified random sample to be based on vocabulary level and developmental stage as well as on age and gender. Post-testing consisted of testing of developmental level and level within the causal relations of animism and dynamism. Significant differences (1.05 level) were found between the experimental and control groups for animism. Within the experimental group, males differed significantly (1.001 level) from females. The elimination of animism appeared to have occurred. For dynamism, significant differences (0.05 level) were found only between concrete operational subjects in the experimental and control groups, indicating a concrete level of operations was necessary if dynamism was to be affected. However, a review of interview protocols indicated that subjects classified as nonanimistic had learned to apply a definition rather than to think in a nonanimistic manner.     

Response bias in college freshmen's responses to mail surveys

This study compared the attitudes and demographic characteristics of an intact group of college freshmen to those of a sample responding to a mail survey and a sample responding to a telephone follow-up. Contrary to expectation, the three samples did not differ significantly in mean attitude responses. The absence of significant mean differences indicated no significant bias in college freshmen's responses to a mail survey. However, a higher percentage of returns was received from females and higher achievers than from males and low achievers.     

Fearfulness in female and male cats

Cats were observed in four moderately frightening novel situations. One of 12 response measures indicated that females are more fearful than males, 1 indicated that males are more fearful than females, and the remaining 10 measures revealed no significant difference between males and females. The results thus yield no evidence of any large and consistent difference in fear between female and male cats. Gonadal hormones do not determine any single pattern of sex difference in fearfulness in different species of mammals. Species-specific patterns of social organization may predict sex differences in fear in studied species more accurately than endocrine factors.     

The performance of college students on piaget-type tasks dealing with distance,time, and speed

Research was done to probe and extend Piaget's theory of the conception of speed. Specifically tested was the hypothesis that there is no hierarchical relationship in performance on the following Piaget-type tasks: conservation of distance, asymmetric series of speeds, one-to-many (circular) speeds, symmetric speeds, time, and proportional reasoning. The research also tested the gender-related performance on these six tasks. One hundred freshman and sophomore college students were shown demonstrations of equipment individually for each of the six tasks. A set of open-ended questions based on the demonstrations was administered to each subject in a 45-minute interview. Subjects were scored as “pass” on a given task if they manipulated objects in certain ways and gave specific types of explanations. A scalogram analysis of the data yielded a z-score of — 3.7 which indicated that subjects passed the task in a certain sequence. The tasks were found to form a unidimensional scale and to be increasingly difficult in the order listed above. A chi-square test for two independent samples showed a significant difference (alpha = 0.05) in performance between males and females on all speed tasks. No significant differences in performance between males and females were found for the distance and time tasks.     

The effect of simulation games and worksheets on learning of varying ability groups in a high school biology classroom

High school biology students who were taught by the simulation game method had comparable achievement gains to the students who were taught using worksheets. The three simulation games used in this study were able to teach factual information as well as the worksheet activities. This effect was constant across ability and sex. There were no significant differences in the retention scores of high ability students utilizing gaming. Also, there was no significant difference in the scores of low ability students utilizing worksheets and low ability students using games. Students' sex was significantly related with retention in the three-way interaction of treatment by ability by sex. Low ability females using simulation games scored higher on retention than low ability females utilizing worksheets. Low ability males utilizing worksheets scored higher on retention than low ability males using simulation games.

Gender Gaps in Achievement and Participation in Multiple Introductory Biology Classrooms

Although gender gaps have been a major concern in male-dominated science, technology, engineering, and mathematics disciplines such as physics and engineering, the numerical dominance of female students in biology has supported the assumption that gender disparities do not exist at the undergraduate level in life sciences. Using data from 23 large introductory biology classes for majors, we examine two measures of gender disparity in biology: academic achievement and participation in whole-class discussions. We found that females consistently underperform on exams compared with males with similar overall college grade point averages. In addition, although females on average represent 60% of the students in these courses, their voices make up less than 40% of those heard responding to instructor-posed questions to the class, one of the most common ways of engaging students in large lectures. Based on these data, we propose that, despite numerical dominance of females, gender disparities remain an issue in introductory biology classrooms. For student retention and achievement in biology to be truly merit based, we need to develop strategies to equalize the opportunities for students of different genders to practice the skills they need to excel.     

THE VALIDITY OF ACADEMIC PREDICTORS FOR BLACK AND WHITE STUDENTS AT A PREDOMINANTLY WHITE UNIVERSITY1

High school grades and both the verbal and mathematical scales of the Scholastic Aptitude Test (SAT-V and SAT-M, respectively) were examined as predictors of college grade point average in groups divided by race and sex. Results indicated that high school grades were not correlated as highly with college grades for black males as for the other three groups, although there were no significant differences in the correlation of either SAT-V or SAT-M with college grades. Moreover, the multiple regression equation for the black male group differed from the equations for the other groups in that SAT-V is the predictor of primary importance rather than high school grades. Weights derived on a random sample of the student body caused substantial shrinkage of the multiple R only in the black male sample. Both black males and black females were significantly overpredicted by such weights. The importance of separate prediction equations for race-sex groupings was emphasized.

Student Participation in Nursing Programs: a Study of their Social Composition Since the Transfer to Colleges of Advanced Education in New South Wales

This paper compares the social origins of 400 nursing students in hospital‐based and 448 nursing students in college‐based programs in New South Wales. Using a specially constructed composite socioeconomic variable for comparison, the preliminary analysis suggests that a middle class bias, presumed to exist by some in the selection of recruits to hospital‐based programs, does not operate in the selection of college recruits. The soundly equitable college recruitment pattern is more marked for females than males. There is a greater proportion recruited to college programs from the group who have delayed entry for more than ten years after leaving school. For students entering directly from school, no significant difference was found in the composite socioeconomic variable in hospital and college programs. The findings also suggest that college programs are more attractive than hospital programs to males entering directly from school.     

Gender ratio and cognitive profiles in dyslexia: a cross-national study

The purpose of this study was to analyze possible gender-related differences in the prevalence of dyslexia. A cross-national comparison of Spain and Guatemala was conducted. Both countries speak the same language but have a different standard of living and educational level. A second purpose of this study was to analyze the cognitive profile of Guatemalan and Spanish males and females children with dyslexia. The log-linear analysis indicated that the number of dyslexics detected was different across the countries but there were no differences as a function of gender. Similarly, there were no significant or meaningful differences between dyslexic males and females in the cognitive processes involved in reading. Therefore, gender differences do not appear to be characteristic of developmental dyslexia.     

The MMPI-2 profile of adults with learning disabilities in university and rehabilitation settings.

The primary purpose of this study was to compare the personality profiles of adults with learning disabilities attending a large state university (8 females, 8 males) to those participating in training programs in a rehabilitation setting (8 females, 18 males), in an attempt to identify affective variables that should be considered in transitional and postsecondary program planning. A secondary purpose of the study was to compare the performance of two groups of adults with learning disabilities (i.e., university and rehabilitation) to a normative group of college students. The mean age for all subjects was between 20 and 23 years. Findings from the study indicated that the personality profiles of individuals with learning disabilities in either a rehabilitation setting or seeking a university degree are significantly different from those of the normative population of normally achieving college students. The rehabilitation group in this study demonstrated feelings of social isolation, poor self-concept, self-doubt, and extreme restlessness. Somewhat different profiles were seen with the university group as they indicated feelings of fear, obsessive thoughts, lack of self-confidence, self-doubt, and extreme self-criticism. Both groups demonstrated profiles of individuals under extreme short- and long-term stress leading to anxiety. The study also reviewed the relevance and appropriateness of using the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) that will have direct application for the assessment and intervention of adults with learning disabilities either in a rehabilitation setting or seeking a university degree.

Changes in self-concept and ideal self-concept after viewing a videotaped speech

Conclusions Several conclusions can be drawn from this study: 1) At midterm there was no difference in self-concept or ideal self-concept factors clearly attributable to the videotape experience. 2) At midterm there was a significant difference on the Pleasantness factor of self-concept between videotaped males and videotaped females. 3) Females videotaped during the first half of the semester significantly increased on the Strength factor of self-concept during the second half of the semester. 4) At the end of the semester there were no significant differences in self-concept or ideal self-concept scores attributable to the time in the semester of the videotape experience. But there was a sleeper effect for females on the Strength factor that began about seven weeks after self-viewing and led to enhancement of self-concept. 5) At the end of the semester females videotaped early in the term had significantly higher scores on the Pleasantness factor of self-concept than did either group of males. 6) The significant interaction of factor x time x sex X time of videotape on the factors of ideal self-concept could not be explained. In future studies of self-concept and ideal self-concept, as related of self-viewing, males and females should be in separate treatment groups. Further research might profitable explore the sleeper effect on the Strength factor for females, the tendency of Strength factor of self-concept scores of males and females to equalize during a speech communication course, and the possibility that the lapse of time between self-viewing and measurement may influence self-concept scores.     

Mathematics achievement and gender: A longitudinal study of selected cognitive and affective variables [grades 6–12]

This study examined the relationship of selected cognitive and affective variables to mathematics achievement for a random sample of 60 students as they progressed through 6th, 8th,10th and 12th grades. A consistent gender difference was found for stereotyping mathematics as a male domain. No consistent significant gender difference between means was found for spatial skills, verbal skill or mathematics achievement. Confidence, verbal skill and spatial visualization were each consistently positively correlated with mathematics achievement for both males and females. No gender difference was found for these correlations. However, spatial skills alone were found to be consistent significant predictors of mathematics achievement for females each year of the study, but not for males. Verbal skill was a consistent significant predictor of mathematics achievement for males, but not for females. The results of this study could lead to a reevaluation of the hypothesis that spatial skills help boys achieve in mathematics.

The comparison of performance by sex of deaf children on the WISC-R

The Performance Scale of the WISC-R was administered to 60 female and 65 male hearing-impaired subjects. The only significant sex difference found was on the Coding subtest, with females outperforming males by a mean scaled score difference of 1.77 points (t = −3.087, p<.01). Subtest intercorrelational results suggest that deaf females possessed significantly better visual-motor coordination and speed, while males demonstrated better spatial analysis and synthesis skills. A principal factor analysis procedure yielded only one factor for each sex. The high degree of factorial similarity between the female and male samples indicated that the underlying construct being measured by the WISC-R Performance subtests does not differ by gender.
