The present study examined the direction and strength of the relation between three different areas academic achievement and working memory with adolescent students. The data analyzed included ratings for inattention, a diagnosis of ADHD (or not), and demographic information for race/ethnicity. Fifty children aged 11 to16 years of age participated in the study. Participants were recruited from several middle schools, homeschooling networks, and churches from a southeastern state of the United States. Each participant completed a standardized achievement test, a behavioral rating scale, and visual and verbal working memory tests. The research questions investigated: 1) the relation between visual and verbal working memory with each of three areas of academic achievement; 2) whether the relation between visual and verbal working memory was strengthened or moderated by inattention. Results found that verbal-auditory working memory (p=p=p=.01). There was a positive relation between the working memory scores and academic achievement, with higher working memory scores predicting higher academic achievement. Due to significant differences with the standardized testing scores between Caucasians and non-Caucasians, the analysis was controlled for ethnicity. The measure of inattention problems did not add significantly to or moderate the prediction of academic achievement by visual or verbal working memory after controlling for ethnicity. Future recommendations included research to support students with low working memory skills and to examine the cultural sensitivity of the working memory batteries.

This study concerns the relationship between student evaluation of instruction and student achievement in the field of management at the community college level. Purposes of the study were to determine the subjective student evaluation of instructor performance in introductory classes of management, student achievement in the class upon completion of the course, and the relationship between the student evaluation of instructor performance and student achievement in knowledge of the course. The population studied was all 10 sections of the Principles of Management course taught by 8 instructors at Del Mar College in Corpus Christi, Texas during the fall semester of 1988. A pretest-posttest design was used to determine student achievement scores. The College Board provided sufficient copies of two versions of the College Level Examination Program (CLEP) tests for Introduction to Management for the pretest and posttest. A special statistical technique using multiple regression was used to calculate an achievement score for each student that was adjusted for entry level knowledge. Student evaluations of instructor performance were paired with the achievement scores and grades students received from the instructor. Additional confidential demographic data was obtained about the students and the instructors. Major findings of the study concluded there is no significant relationship between the student achievement scores and student evaluation of instructor performance. There was a wide variance in correlation of student grades and student achievement scores when individual sections or individual instructors were examined. The overall correlation of grades and achievement scores was statistically significant and was the highest of any of the factors studied. The study recommends using more objective measures of student achievement in evaluating faculty performance.

The purpose of this quantitative study was to investigate factors that contribute to the academic success of African American males in the Blount County Area. More specifically, the study was focused on the perception of the participants concerning noncognitive, demographic, and institutional variables associated with the academic success of African-American males. The participants for this study were attendees of four local churches: Mount Pleasant A.M.E. Zion, Rest Haven Missionary Baptist Church, St. John Missionary Baptist Church, and St. Paul A.M.E. Zion Church. Each of the four churches is located in Blount County, Tennessee. Participants were male and female adults of varied ages and ethnic classifications but were all familiar with the focus area. Research supported the suggestion that both cognitive and noncognitive variables contribute to the academic success of African American males in the Blount County Area. The data were collected and analyzed using a 27-question survey measured on a 5 point Likert scale. The last section of the survey instrument was composed of 3 open-ended questions. Seven research questions served as the bases for this study and the data were analyzed using a series of single-sample t tests. Results indicated that participants agreed that noncognitive, demographic, and institutional factors are contributors to the academic success of African American males in Blount County, Tennessee.

Over the past 2 decades, the number of adult learners seeking an online education has dramatically increased, but student retention and degree completion rates for adult students are lower than those of other student populations. Research has shown that adult learners working full time achieve at higher levels than adult learners who are not working full time and that intrinsic motivation is positively correlated with academic achievement. However, whether the relationship between intrinsic motivation and academic achievement is moderated by level of work commitment has not been previously investigated. For this study, in which the composite persistence model served as the foundation, 137 online adult learners were recruited. A sequential multiple regression was used to investigate whether the relationship between intrinsic motivation, as measured by the Motivation Strategies for Learning Questionnaire (MSLQ), and academic achievement, as measured by self-reported grade point average, was moderated by level of work commitment, as measured by self-reported hours of work per week, while statistically controlling for academic competencies, as measured by 4 subscales of the MSLQ. Intrinsic motivation and level of work commitment did not display a statistically significant correlation with academic achievement, and results showed that level of work commitment did not moderate the relationship between intrinsic motivation and academic achievement. The findings indicated the possibility that education is synergistically related to work commitment. Online programs may use the findings from the study to better support online adult learners and create positive social change by offering internships and mentorships locally that help to connect education to work commitment.

The purposes of the study were: to determine the relationship between class size and academic achievement among university students in first-semester calculus classes, and to compare opinions about the instructor, course, and classroom learning environment of university students in small first-semester calculus classes with those in large classes. The sample consisted of 225 university students distributed among two large and two small sections of first-semester calculus classes taught at the University of Texas at Arlington during the fall of 1987. Each of two tenured faculty members taught a large and small section of approximately 85 and 27 students, respectively. During the first week of the semester, scores from the Calculus Readiness Test (CR) were obtained from the sample and used as the covariate in each analysis of covariance of four periodic tests, a comprehensive final examination, and final grade average. The CR scores were also used in a logistic regression analysis of attrition rates between each pair of large and small sections of first-semester calculus. Three semantic differentials were used to test the hypotheses relating to student opinion of the instructor, course, and classroom learning environment. It was found that for both pairs of large and small first-semester calculus classes there was no significant difference in the adjusted means for each of the four periodic tests, the final examination scores, the final grade averages, and the attrition rates. It was also found that the means of the student evaluation of the course by students in small and large classes were not significantly different, and the results of the student evaluations of the instructor and classroom learning environment by students in small and large first—semester calculus classes were mixed.

The problem of this study was to determine the value of Scholastic Aptitude Test scores and high school percentile rank for predicting a student's achievement in American history at North Texas State University. The study also sought to determine what, if any, difference existed between male and female students, students of different ethnic backgrounds, and students of different semester classification with respect to learning achievement in American history.

Résumé La présente thèse doctorale vise à déterminer sous quelles conditions la garde non-maternelle est associée (positivement/négativement) au niveau de stress et au développement cognitif des enfants. Elle comporte une recension des écrits et trois articles empiriques. Le premier article présente une recension des écrits (de type méta-analytique) qui synthétise les études portant sur le stress des enfants en services de garde et ayant utilisé le niveau de cortisol comme indicateur. Les résultats montrent que la garde non-maternelle est associée au niveau de stress des enfants, se reflétant dans des concentrations de cortisol élevées. Les niveaux de stress élevés s’observent particulièrement chez les enfants qui au départ ont tendance à être retirés, anxieux ou qui sont gardés dans un milieu de faible qualité. Cependant, certains éléments indiquent que les élévations de cortisol à la garderie sont temporaires et qu’elles disparaissent au fur et à mesure que l’enfant s’adapte à son milieu. Le deuxième article de thèse, réalisé dans le contexte de l’Échantillon longitudinal national des enfants et des jeunes [ELNEJ] (n = 3093), vise à déterminer dans quelle mesure l’association entre la fréquentation des services de garde et l’acquisition du vocabulaire réceptif au préscolaire dépend du milieu familial de l’enfant. Les résultats indiquent qu’à l’intérieur du groupe d’enfants défavorisés, ceux ayant été gardés à temps plein dans la première année de vie obtiennent des scores supérieurs sur une mesure de vocabulaire réceptif administrée à 4 ½ ans, comparativement aux enfants restés à la maison avec la mère (d=0.58). Le troisième article, réalisé dans le contexte de l’Étude longitudinale des enfants du Québec [ELDEQ]; (n=2,120), vise à documenter les bénéfices à long terme de la fréquentation des services de garde par les enfants issus de milieux désavantagés sur la préparation scolaire et les compétences académiques. Les résultats révèlent que les enfants dont la mère n’a pas terminé ses études secondaires obtiennent de meilleurs résultats sur une mesure de préparation scolaire cognitive (d=0.56) et de vocabulaire réceptif (d=0.30) en maternelle, et de connaissance des nombres (d=0.43) en première année, s’ils ont fréquenté un service de garde sur une base régulière. Par ailleurs, la garde non-parentale n’est pas associée aux compétences cognitives des enfants de milieux sociaux favorisés. L’objectif du quatrième article est d’examiner les facteurs de sélection quant à l’utilisation des services de garde dans le contexte de l’ELDEQ. Les résultats montrent que l’absence d’emploi de la mère pendant la grossesse, le faible niveau d’éducation de la mère; le revenu insuffisant de la famille, avoir plus de 2 frères et sœurs, la surprotection maternelle, et le faible niveau de stimulation cognitive sont associés à une faible utilisation des services de garde (30.7% de l’échantillon québécois). En d’autres termes, les enfants qui sont les plus susceptibles de retirer des avantages des services de garde sur le plan du développement, en raison de la présence de facteurs de risque dans leur milieu familial, sont aussi ceux qui utilisent le moins les services de garde. / Abstract The present doctoral thesis aims at determining under which conditions child-care experiences may be associated (positively or negatively) with children’s stress levels and cognitive development. It comprises one literature review and three empirical studies. The first study is a literature review (meta-analysis type) which summarizes the studies on child-care experiences and children’s stress (as indexed by cortisol) in order to identify individual and environmental conditions under which child-care is associated with elevated cortisol concentrations. Findings suggest that child-care may be more stressful, as reflected in higher salivary cortisol concentrations, for children who are less socially competent or who received low quality child-care services. However, some pieces of evidence suggest that cortisol elevations in child-care are transient and fade out as children grow older The second study uses data from the National Longitudinal Survey of Children and Youth [NLSCY]; (n=3093). The goal is to determine whether the association between non-maternal care and receptive vocabulary skills depend upon children’s home environment. Results show that children from low socioeconomic status who received full-time (< 25 hours/week) child-care services in their first year of life obtain higher scores on a measure of receptive vocabulary at 4 ½ years than those who were cared for by their mothers (d=0.58). The goal of the third study is to document further the longer-term benefits of early child-care attendance on disadvantaged children’s school readiness and school achievement. This study uses data from the Quebec Longitudinal Study of Child Development [QLSCD]; (n=2120). Findings reveal that child-care services produce benefits over maternal care for children from low educated mothers on a measure of receptive vocabulary (d=0.30) and cognitive school readiness (d=0.56) in kindergarten, and number knowledge in first grade (d=0.43). Overall, child-care services produce no advantage or disadvantage for children who do not experience risks in their home. The objective of the fourth study is to identify key family factors associated with low child-care services utilization, using the QLSCD sample. Results show that maternal unemployment during pregnancy, low levels of maternal education; insufficient household income, having more than two siblings, high levels of maternal overprotection, and low levels of cognitive stimulation are associated with lower child-care services use (30.7% of the Quebec sample). In sum, children who are the most likely to benefit from child-care services in terms of their development are also those who are less likely to receive it.

The computer-based testing mode has received limited research as a task condition for elementary students as it relates to comprehension for both narrative and expository text. The majority of schools now use computer-based testing to measure students' progress for end of the year exams. Additionally, schools are also delivering state-wide assessments like the Florida Comprehension Assessment Test through computer-based testing instead of paper-pencil testing. There is little research to indicate whether computer-based assessments are an effective way to measure student progress. This study investigated the effects of an interactive computer-based reading strategy on student comprehension for both expository and narrative passages. The intervention evaluated students' percentage of learned strategy use and comprehension accuracy for expository computer-based passages. Additionally, the intervention measured whether students generalized the learned strategy when given a paper-pencil narrative passage and whether generalization of strategy use improved comprehension vi accuracy. This study used an A-B-A-B design across participants, with a follow-up phase. The results from the data showed that all students made significant increases in strategy use from baseline to follow-up. Additionally, all the students had an increase in comprehension accuracy from baseline to follow-up for both computer and paper-based passages. All students were able to generalize successfully the strategy use to narrative passages, and improved their comprehension accuracy of narrative passages. The effects of the study suggest the value of teaching students the interactive computer-based reading strategy for students who struggle with passage comprehension. / by Jamie L.
