Koppitz emotional indicators as predictors of kindergarten children's learning-related behavior

Koppitz Emotional Indicators (EIs) were used to predict the learning-related behavior of kindergarten children (N = 161, 82 males, 79 females) on the Lock Box and Guide to the Child's Learning Style (GCLS). Three criterion groups (well adjusted, adequately adjusted, possibly maladjusted) were designated by the number of EIs on the children's Human Figure Drawings (HFDs). Scores for the Lock Box and GCLS were subjected to principal components analyses with varimax rotation. The resultant three-factor solution on the Lock Box and four-factor solution on the GCLS were submitted to a direct multiple discriminant analysis. Findings indicated the three EI groups could be differentiated. Univariate F tests showed that EIs significantly predicted scores on the GCLS factors while Lock Box factors were not well predicted. Although findings support the use of EIs as general estimates of learning-related behavior, a classification analysis showed that the diagnostic utility of the EIs was only marginally above chance for kindergarten children who obtained pathological scores on the HFD.

The differentiated child behavior observational system

The Differentiated Child Behavior Observational System (DCB, Ross, 1971) which provides for systematic recording of children's interactions in ongoing classroom activities, was applied in 48 classrooms with children aged five to eight. Three groups were studied: the first, representing a nontraditional, open-classroom approach was drawn from the Bank Street School for Children (middle-income); the second, with a similar approach, from Bank Street Follow Through classes in public schools (low-income); and the third, from traditional classes in public schools (low-income).The groups showed striking differences in amount of children's interactions, with significantly greater amounts in the two nontraditional groups. Analysis of the content of the interactions revealed further important differences. The Bank Street School and Bank Street Follow Through groups totalled significantly more higher-order cognitive statements and questions, and more autonomous behavior. Results indicated that although in SES background, Follow Through classes were more like the traditional classes, the interactions of the Follow Through children were more like those of the (nontraditional) Bank Street School.1 This presentation is limited to the most salient points of definition. A comprehensive listing of examples for each subcategory component is presented in the Observer's Manual.2 The incidence of such behaviors is reflected by the following mean total frequencies for the three groups: Bank Street School = 1.9, Follow Through = 10, and Comparison = 10.More recent work with the DCB can be found in Sylvia Ross, Herbert Zimilies and David Gerstein, Children's Interaction in Traditional and Nontraditional Classrooms.

On the fracture resistance of adhesively jointing structures

INTRODUCTION Adhesive bonding technology has been widely applied in modern structures in industries such as automotive, aerospace and in microelectronic device. The core idea of this technology is to bond two similar or dissimilar structure members with a thin continuous interface layer which can provide far better stress transfer across the interface than those traditional point-wise joining technologies such as spot welding, riveting and bolting. Furthermore, the damage tolerance proper…     

Child maltreatment in the "children of the nineties": a cohort study of risk factors

AIM: To analyze the multiple factors affecting the risk of maltreatment in young children within a comprehensive theoretical framework. METHODS: The research is based on a large UK cohort study, the Avon Longitudinal Study of Parents and Children. Out of 14,256 children participating in the study, 293 were investigated by social services for suspected maltreatment and 115 were placed on local child protection registers prior to their 6th birthday. Data on the children have been obtained from obstetric data and from a series of parental questionnaires administered during pregnancy and the first 3 years of life. Risk factors have been analyzed using an hierarchical approach to logistic regression analysis. RESULTS: In the stepwise hierarchical analysis, young parents, those with low educational achievement, and those with a past psychiatric history or a history of childhood abuse were all more likely to be investigated for maltreatment, or to have a child placed on the child protection register, with odds ratios between 1.86 and 4.96 for registration. Examining strength of effect, the highest risks were found with indicators of deprivation (3.24 for investigation and 11.02 for registration, after adjusting for parental background factors). Poor social networks increased the risk of both investigation (adjusted OR 1.93) and registration (adjusted OR 1.90). Maternal employment seemed to reduce the risk of both outcomes but adjusted odds ratios were no longer significant for registration. After adjusting for higher order confounders, single parents and reordered families were both at higher risk of registration. Reported domestic violence increased the risk of investigation and registration but this was no longer significant after adjusting for higher order variables. Low birthweight children were at higher risk of registration as were those whose parents reported few positive attributes of their babies. CONCLUSIONS: This study supports previous research in the field demonstrating that a wide range of factors in the parental background, socio-economic and family environments affect the risk of child maltreatment. By combining factors within a comprehensive ecological framework, we have demonstrated that the strongest risks are from socio-economic deprivation and from factors in the parents' own background and that parental background factors are largely, but not entirely, mediated through their impact on socio-economic factors.     

Asian students in Australia: sources of the academic self

Students’ motivation is known to be influenced by both internally referenced and externally referenced factors. Internally referenced factors include self-processes (sense of competence and affect), whereas externally referenced factors include significant others (parents, peers and teachers). Using the Facilitating Conditions Questionnaire, the relations of the internal and external factors were examined. By comparing Anglo and Asian origin students in Australia, the study aims to reveal the most prominent external factors that contribute to shaping the self-processes of Asian students (88 male and 110 female) and Anglo students (384 male; 345 female). Confirmatory factor analysis identified seven factors (competence, affect, parent, peer positive, peer negative, teacher and motivation for high marks). The relations between internal and external factors were found to be similar between ethnic and gender subsamples. Parents and teachers were identified as having the strongest impact on self-processes and motivation for high marks. For this sample of students in an Australian education system, their sources of school-related self-processes are similar to those of their Anglo peers’, but their higher affect to learning may be an important cause for academic success.

Academic pressures and the black adolescent

This study examined the relationships among social class, race, and academic pressure in an inner city public high school. Previous research outside the inner city on U.S. and English high school students, who were predominantly white, has yielded four major factors: parental stress, peer stress, importance of school, and fear of failure. The primary purposes of this study are (1) to measure academic stress in an inner city setting, (2) to observe differences and similarities between blacks and whites and between middle- and lower-class adolescents, and (3) to determine if the four previously observed factors would be as pertinent for this sample as they were for previous samples. Race differences were observed on 4 of 10 factors with blacks indicating significantly more pressure than whites. A race by class interaction was observed on one factor and no significant differences were observed on the five remaining factors.

A Factor Analytic Study of the Infant-Toddler and Early Childhood Versions of the HOME Inventory Administered to White, Black, and Hispanic American Parents of Children Born Preterm

Factor analyses were performed on the Infant-Toddler and the Early Childhood versions of the HOME Inventory for 3 groups (blacks, whites, and Hispanics) of premature, low-birthweight children. Participants lived in 8 different U.S. cities. On the IT-HOME, 5 factors were originally retained for each group using the principal factors method of extraction. Factor structures for blacks and whites were similar, accounting for 85% and 75% of the variance, respectively. The structure for Hispanics was somewhat different; a 7-factor solution accounting for 65% of the variance was most interpretable. For the EC-HOME, 6 factors were retained for both black and white groups, accounting for 80% and 73% of the variance, respectively. For Hispanics, an 8-factor solution accounted for 59% of the variance. The factor structures for blacks and whites were largely in agreement with the current organization of items into subscales. The fit for Hispanics was not quite as good, but most factors also corresponded to current subscales.     

A comparison of visual and auditory processing tests on the Woodcock-Johnson Tests of Cognitive Ability,Revised and the Learning Efficiency Test-II

A comparison of the visual and auditory processing factors of the WJR Tests of Cognitive Ability and the visual and auditory memory factors of the Learning Efficiency Test, II were examined for 120 undergraduate college students. Repeated measures ANOVAs revealed two significant performance differences: between the WJR COG and LET-II visual processing factors and between the WJR Broad Cognitive Ability index and the LET Global Memory score. Although there was no significant performance difference on the WJR COG and LET-II auditory processing factors, the two measures were independent, accounting for less than 4% shared variance. Similarly, WJR COG and LET-II visual processing factors also were independent. It was hypothesized that differing levels of task complexity, such as order vs. unordered memory retrieval requirements, semantic meaningfulness of the material presented, and rehearsal and/or presence of verbal interference components, represent distinct performance outcome measures of visual and auditory processing by the WJR COG and LET-II. © 1997 John Wiley & Sons, Inc.     

Interrelationships between the Choice of College Major,the ACT and the Sixteen Personality Factor Questionnaire

Abstract

The usefulness of the ACT and 16 PF for discriminating between decided and undecided college students was investigated. Different discriminant functions were derived for males and females, indicating a need for different counseling procedures. A canonical correlation analysis of the ACT versus the 16 PF indicated a strong relationship between the two instruments, even though redundancies were low. Six factors emerged in a factor analysis of the ACT, 16 PF, sex, hours earned, GPA, and group: an academic potential factor, four personality factors, and a school achievement factor.

Creativity and the Solving of Social Problems

Abstract

From a national sample of secondary school teachers, raw problems perceived by teachers were collected. These problems served as the basis for a 105 problem checklist which was administered to a second teacher sample for verification. Of the problems contained on the checklist, teachers indicated that forty-two were bothersome, frequently occurring, or both. Teacher bothersomeness and frequency responses were factor analyzed resulting in seven salient factors for the bothersomeness data (Efficiency, Support, Invigoration, Control, Inclusion, Nurturance, Influencing) and seven factors for the frequency data (Security, Remediation, Invigoration, Control, Satisfaction, Support, Time). With respect to bothersomeness factors, Factor III (Invigoration) and Factor IV (Control) possess the greatest number of significantly bothersome specific problems. These findings suggest that particular human needs, especially Invigoration and Control, are exacerbated when the role of secondary teacher is assumed.
