This investigation compared achievement of boys and girls in second grade who were seven years old in June, July, and August of 1983 to the boys and girls in second grade who were eight years old in September, October, and November of 1983. The students were tested using the Iowa Test of Basic Skills using the following areas: reading, total math, and composite scores. The study also looked at the correlation of sex and age of students who had been retained in first grade. A comparison of teacher grades to standardized test scores and ability grouping was also presented. One way analysis of variance was applied to the test results. A chi square test of independence was conducted on students retained in the first grade to determine if interaction between sex and age was indicated. Older children scored higher in all three areas measured, while girls scored higher in reading. This may seem contradictory, but is not. Age was significant beyond the .05 level, while sex was significant beyond the .001 level. This difference is explained by the extremes in means for younger boys and older girls. Since first grade curriculum emphasizes reading, this gave girls a definite advantage over …

The purposes of this study were to determine if a kindergartener's developmental stage correlates with subsequent scholastic achievement, to determine whether developmentally younger children who repeat kindergarten attain higher academic achievement than developmental 1y younger children who do not repeat kindergarten, and to investigate the relationship between head circumference, developmental age, and achievement. Ninety-seven kindergartners of various ethnicity and socio-economic status were administered the Gesell School Readiness Screening Test to determine developmental age and were followed academically for three years. Head circumference was noted periodically to measure brain growth. The hypotheses predicted significant positive correlations between developmental age in kindergarten and scores on later achievement tests. Further, it was predicted that children below 5.3 years in developmental age who delayed entrance to first grade would score significantly higher on first grade achievement tests than match-paired promoted students. It was hypothesized that there would be significant correlations between head circumference growth and (a) gains in achievement test scores and (b) developmental age at kindergarten. The first hypothesis, tested by Pearson Product Moment Correlations, established the existence of significant correlations between developmental ages of test subjects and their scores on four academic achievement tests. The results indicated that developmental age was a …

The purpose of this study was to determine the effectiveness of a transitional first grade program. A comparison of reading and math achievement and school attitude was the focus of the study. The study utilized a pretest/posttest design. The group of regular first grade students who qualified for the transitional program but attended regular first grade was the control group. The group of transitional first grade students was the experimental group. The regular first grade students received formal instruction in all academic areas. The experimental group received no formal instruction. All students were pretested and posttested using the Iowa Test of Basic Skills and the Minnesota School Attitude Survey. Testing was administered to small groups of five or less by the researcher. Scoring was done also by the researcher. An analysis of covariance was used to determine if a significant difference existed between the groups. The analysis of covariance did not produce a significant F at the .05 level when applied to the Iowa Test of Basic Skills except for reading for boys in both groups. The numbers in each cell were low and no further comparisons were made. Due to a testing date that was approved late in the …

The purposes of this study were to determine whether brain growth spurts occur in normal pupils and to determine whether there was a uniform difference in head circumference between boys and girls. Subjects were 3,062 normal elementary pupils, grades one through six, from one suburban school district. Fiberglass measuring tapes were used to measure pupils' head circumference. The hypotheses of the study predicted that the relationship between head circumference and age would be linear. Further, it was predicted that the differences in head circumference between boys and girls would be uniform over seven specified ages. The first hypothesis was tested using a test for linear trend and deviation from linear trend using the General Linear Models procedure. The results indicated that there was a significant linear trend between head circumference and age. The test for deviation from the linear trend was not significant. This would suggest that any deviation from a straight line observed in the data can be attributed to chance. It was concluded that since there was no significant deviation from linear trend, it would suggest a continuous growth of the brain for the ages included in this study. A two-way analysis of variance was used to test …
