The role of absenteeism in the prediction of math achievement on the basis of self-concept and motivation: TIMSS 2015 in Serbia

This study examines how students? absenteeism moderates the relationship of math self-concept and motivation to learn math on one side and the achievement in the TIMSS 2015 math test on the other. The stratified random sample consists of 4036 fourth grade pupils from 160 primary schools in Serbia. Separate regression models were made for four levels of frequency of students? absenteeism. The results show that self-concept makes a positive contribution to the prediction of achievement, and motivation a negative one. Additionally, with the increase of absenteeism the importance of self-concept drops and that of motivation grows. The analysis of variance confirmed that along with the increase of absenteeism, students express lower levels of self-concept, while the level of motivation does not change. The most important conclusion is that regular class attendance contributes to the students? math self-concept and consequential achievement by developing their experiences of success in math. The usefulness of the motivation scale for predicting math test performance is discussed.

Genetic and Environmental Influences on Self-Concept in Female Preadolescent Twins: Comparison of Minnesota and Seoul Data

AbstractIt has been argued that culture significantly influences the developmental basis of self-concept. The goal of the present study is to compare the relative importance of genetic and environmental factors to explain individual differences in various dimensions of self-concept in female preadoles- cents of Minnesota in the United States and Seoul in South Korea. Two hundred and eighteen monozygotic (MZ) and 137 dizygotic (DZ) twin pairs from the Minnesota Twin Family Study (MTFS) and 74 MZ and 42 DZ twin pairs from the Seoul Twin Family Study (STFS) completed the 6 cluster scales of the Piers–Harris Children's Self-Concept Scale (P–H). The 6 cluster scales of the P-H include Popularity, Physical Appearance and Attributes, Behavior, Intellectual Competence and School Status, Anxiety, and Happiness and Satisfaction. Univariate model- fitting analyses were performed. In both samples, a model incorporating shared and nonshared environmental influences fitted the data best for Popularity, Anxiety, and Intellectual Competence and School Status, whereas a model including additive genetic and nonshared environmental factors provided the best fit for Physical Appearance and Attributes, and Behavior. The univariate model did not yield an adequate fit for Happiness and Satisfaction. For Physical Appearance and Attributes, and Intellectual Competence and School Status, estimates of additive genetic and environmental factors were significantly different between the MTFS and the STFS samples. For Popularity, Anxiety, and Behavior, however, the genetic and environmental estimates were comparable between the two samples.

Comparing the Self-Concepts of Persons With and Without Physical Disabilities

Tam and Watkins (1995b) explored the basis of self-concepts of physically disabled and nondisabled Hong Kong Chinese adults and developed the hierarchical multidimensional self-concept models. Two questionnaires that measure self-concept were developed and validated for those groups. The questionnaires share 41 common items in 6 self-concept areas. In the present study, the 2 groups' responses were compared via univariate analysis of variance. The nondisabled participants (n % 200) were found to have statistically significantly higher means than their disabled counterparts (n % 214) in total self-concept, material self-concepts, and physical self-concepts. There were no significant differences in their family, social, and work self-concepts. The nondisabled participants reported greater openness (indicated by higher self-criticism scores).
