Age and Sex Differences in Motor Performance of 3 through 6 Year Old Children

Abstract

This study examined the relationship of age and sex to the performance of 3, 4, 5, and 6 year olds on seven motor performance test items. Although significant age and sex differences were found on most of the motor tests, it appears that age generally was related more to performance than was gender. Overall, change with age was fairly linear except perhaps for balancing and a general tapering in improvement in the 5 to 6 year old category. On the tests of throwing and balancing, gender was as important as age, or more so, in its relationship to performance. Boys were superior to girls at all ages on the throwing tests; girls were superior to boys at age 6 on the Balance test. Gender differences of a lesser magnitude were found on the Speed Run and Standing Long Jump tests with the performance of boys generally being superior to the performance of girls. Thus, it appears that gender differences in motor performance occur as early as the preschool years. Interestingly, except for the Balance test, on all the tests the 3 and 4 year old boys performed similarly and the 5 and 6 year old boys performed similarly. For the girls there were more significant differences from year to year in performance, with the data generally indicating at least three distinct skill groups for girls from age 3 to 6.     

PASS,an alternative method of teaching introductory psychology

A new teaching method based on positively reinforcing attempts at mastery was introduced and empirically tested to determine its validity. The program, labeled Programmed Achievement Study System (PASS), makes use of traditional learning principles by providing rewards (bonus points) contingent upon reaching specified mastery criteria. Specifically, college students enrolled in introductory psychology were awarded additional points if they demonstrated mastery of concept areas on retake quizzes administered during a given week. PASS students, as compared to a control condition, demonstrated higher performance on a final examination given at the end of the semester. These results suggest that the PASS contingencies are preferable to those contingencies operating in more traditional classrooms. A theoretical rationale based on the principles of operant conditioning is discussed.     

The Nonreciprocating Robot: Effects on Verbal Discourse, Social Play, and Social Referencing at Two Years of Age

2-year-old children interacted with a robot in a large playroom while their mother sat quietly in the corner. Identical vocalizations from the robot had very different effects on 3 dimensions of the children's behavior when the vocalizations were embedded in reciprocating and nonreciprocating social structures. The reciprocating robot produced (1) more topic-maintaining verbal dialogue, (2) less physical and more linguistically mediated social play, and (3) gender-specific effects on the children's tendency to visually reference their mother during the play session. The data are discussed with reference to the frequently encountered assumption that reciprocal social structures have an impact on children's behavior when the quantity and other qualitative dimensions of social stimulation are held constant, and with reference to the children's attributions about the robot as a social partner.     

The Essence of Education: Whitehead and the Spiritual Dimension

Whitehead's contention that the essence of education is that it be religious has been widely overlooked by many of his adherents who have found it a difficult, or even embarrassing, concept with which to deal. But what did Whitehead mean by religious? In Britain there is currently a deep interest in what is being termed the, "spiritual dimension of education" which is itself to be seen in the context of the postmodern rejection of positivistic modes of thought which have dominated educational discourse in recent decades. This article examines Whitehead's own concept of religion both in his explicit academic work and in his assessment of what we might term, indirect education. It goes on to suggest links with other key thinkers, in particular William James, Soren Kierkegaard, and Ludwig Wittgenstein.     

Cognitive Difficulties in Struggling Comprehenders and Their Relation to Reading Comprehension: A Comparison of Group Selection and Regression-Based Models

ABSTRACT

Difficulties suppressing previously encountered but currently irrelevant information from working memory characterize less skilled comprehenders in studies in which they are matched to skilled comprehenders on word decoding and nonverbal IQ. These “extreme” group designs are associated with several methodological issues. When sample size permits, regression approaches permit a more accurate estimation of effects. Using data for students in Grades 6 through 12 (n = 766), regression techniques assessed the significance and size of the relation of suppression to reading comprehension across the distribution of comprehension skill. After accounting for decoding efficiency and nonverbal IQ, suppression, measured by performance on a verbal proactive interference task, accounted for a small amount of significant unique variance in comprehension (less than 1%). A comparison of suppression in less skilled comprehenders matched to more skilled comprehenders (48 per group) on age, word reading efficiency, and nonverbal IQ did not show significant group differences in suppression. The implications of the findings for theories of reading comprehension and for informing comprehension assessment and intervention are discussed.     

The disadvantaged student at a liberal arts college

In the fall of 1969, a program to expand educational opportunities (EEO) for economically disadvantaged students was initiated at Macalester College. During the first three years of the program, the percentage of non-white students at the College rose from 3% to approximately 15%.Average grades for the EEO students were approximately one standard deviation below those of a random non-EEO sample, similar to the differences in high school grades between the two groups. However, the EEO students persisted at Macalester College at a slightly higher rate than non-EEO students. The EEO students also were more likely than non-EEO students to major in the behavioral/social sciences and less likely to major in the fine arts, humanities, and physical sciences.     

The impact of instructional practices in Grades 1 and 2 on reading and spelling achievement in high poverty schools

The objective of this investigation was to examine how instructional practices in 107 first- and second-grade classrooms in 17 high poverty schools moderate the impact on literacy outcomes of literacy-related skills students bring to the classroom. Ratings of teaching effectiveness and time allocation to literacy activities were obtained. Twenty time allocation variables were reduced into seven patterns of literacy activities that were examined as predictors of reading and spelling outcomes. Students’ initial reading ability and interactions of teaching effectiveness ratings by time allocation components predicted reading and spelling outcomes. Discussion centers on immutable versus flexible views of reading development and analytic approaches to examining instructional practices.     

Differences in achievement not in intelligence in the north and south of Italy: Comments on ,

Lynn (2010a, 2010b) argued that individuals from south Italy have a lower IQ than individuals from north Italy, and that these differences in IQ are at the basis of north–south gap in income, education, infant mortality, stature, and literacy. In the present paper, we discuss several theoretical and methodological aspects which we regard as flaws of Lynn's studies. Moreover, we report scores of southern Italian children on Raven's Progressive Matrices and a north–south comparison for the PASS theory of intelligence as measured by the Cognitive Assessment System (Taddei & Naglieri, 2006). Both results reveal similar levels of performance of northern and southern Italian children in fluid intelligence and PASS (Planning, Attention, Simultaneous, and Successive) cognitive abilities.     

Using the Cognitive Apprenticeship Web-based Argumentation System to Improve Argumentation Instruction

This study investigated how the instruction of argumentation skills could be promoted by using an online argumentation system. This system entitled ??Cognitive Apprenticeship Web-based Argumentation?? (CAWA) system was based on cognitive apprenticeship model. One hundred eighty-nine fifth grade students took part in this study. A quasi-experimental design was adopted and qualitative and quantitative analyses were used to evaluate the effectiveness of this online system in measuring students?? progress in learning argumentation. The results of this study showed that different teaching strategies had effects on students?? use of argumentation in the topics of daily life and the concept of ??vision.?? When the CAWA system was employed during the instruction and practice of argumentation on these two topics, the students?? argumentation performance improved. Suggestions on how the CAWA system could be used to enhance the instruction of argumentation skills in science education were also discussed.
