Objective: This study aimed to develop and apply the home connection program for promoting the mathematical interaction of parents of 3-year-olds. Methods: We surveyed questionnaires for 36 parents and interviewed 3 parents of 3-year-olds for the development of the program. Twenty-one 3-year-olds were selected as participants in the program. Quantitative data from a checklist for parent's mathematical interaction were analyzed using repeated measures ANOVA. Qualitative data from self-evaluation of teachers and parents were categorized and analyzed in terms of meaning. Results: Based on the home connection program, the session were provided in the following order [educare center activities ${\rightarrow}$ home-linked activities ${\rightarrow}$ home+educare integrated activities] and in each session, the three-step course [sharing of thinking ${\rightarrow}$ gathering of thinking ${\rightarrow}$ broadening of thinking] was applied. Implementation of this program led to promoting parental mathematical interaction. Conclusion/Implications: This study will lead to follow-up studies that reveal positive effects of our program.

This study aimed to develop and validate a scale which could be used to evaluate mathematical interactions of parents with their young children. The subjects comprised 408 mothers of 4-6-year-old children. Means, standard deviation, $x^2$, Cramer's V, exploratory factor analysis, confirmatory factor analysis, Pearson correlations, and Cronbach's ${\alpha}$ were calculated. First, 49 items were developed through a review of relevant research, parent interviews, confirmation of item adequacy and content validity. These items were then edited down to a final list of 24 items representing 4 factors identified by exploratory factor analysis. Second, this 24-item. 4-factor scale was shown to have adequate construct validity, norm validity, and reliability by confirmatory factor analysis, Pearson correlation analysis, Cronbach's ${\alpha}$. In conclusion, the final mathematical interaction scale for young children's parents was composed of 24 items with 4 factors: "interaction regarding numbers and operations, measurements, and patterns", "interaction regarding data collection and result presentation", "interaction with picture books", and "interaction regarding shapes and figures"

Objective: The purpose is to verify that whether there are significant correlation between parent-teacher cooperation, quality of home environment, and mathematical interaction of parents and cognitive development of 3-year-olds, and the quality of home environment and mathematical interaction mediate the relationship between the parent-teacher cooperation and the cognitive development. Methods: A test was performed on 110 3-year-olds enrolledin a daycare center located in city S, and a questionnaire survey was conducted on their parents. We analyzed our data using SPSS WIN 21.0 and pearson's correlation, tested the mediating effect using regression, and used the Sobel test to check significance of the mediating effect. Results: Cognitive development of 3-year-olds was correlated with the parent- teacher cooperation, the quality of home environment, and mathematical interaction of parents. The quality of home environment showed complete mediating effect on the relationship between the parent-teacher cooperation and the cognitive development, and the mathematical interaction showed complete mediating effect on the relationship between the parent-teacher cooperation and the cognitive development. Conclusion/Implications: The parent-teacher cooperation indirectly predicts the cognitive development through the quality of home environment and the mathematical interaction. This research can contribute to the development of the family- institution connection program to facilitate the parent-teacher cooperation.

The purpose of this study was to explore status of mathematical interactions between parent and child and use of mathematical materials at home. For this purpose, questionnaires were developed. The framework of the questionnaires consisted of mathematics education content domains. 276 parents(4-5 year old children) in J Province responded to the questionnaires, which were analyzed according to the level of home income, the mother's work conditions and the mother's level of education. The results were as follows: First, between parent and child mathematical interaction at home showed a 2.84 score in average and frequency of mathematical interaction expressed in the domains of 'Understanding of regularity', 'Measurement', 'Growing number sense', 'Space and shapes', 'Organizing data and showing results'. The domains of 'Growing number sense', 'space and shapes', and 'measurement' showed significant difference only by mother's level of education. The higher the mother's level of education, the more frequent the mathematical interaction between parent and child. Second, the use of mathematical materials showed an average score of 1.18, which means mathematical materials were practically not used at home. Also, the use of mathematical materials showed a slightly significant difference when measures against the levels of home income and the mother's level of education. The results showed a significant difference in parent-child mathematical interactions, and the possession and use of mathematical materials when measures against by level of home income and the mother's work conditions. Therefore, the results of this study suggest that the parent education program for mathematical interaction to apply at home and mathematics curriculum to be connected early in childhood education institution and home should be developed for parents.

Schools are expected to ultimately moderate the difference of inequality issues among social groups and reduce the achievement gaps. This study investigates this expectation, in particular, how students' mathematics achievements are influenced by their parents' education at the individual level and by collective responsibility for teaching at the school level as well as the interaction of the two. Using a two-level hierarchical linear model, this study indicates that a school collective responsibility has a larger positive effect on students' mathematics achievement when their parents' education level is high. This means that school's collective responsibility accelerates inequity in students' mathematics achievement. Knowing that collective responsibility has less of an effect on students whose parents' education is not high, researchers, schools, and school districts should continue to search for school effects that have more of a positive impact on the relationship between mathematics achievement for students whose parents' education is not high in order to have more equitable results for all students.

본 연구에서는 중학교 2학년의 수학 학업성취도에 대한 교사와 부모의 성취압력과 수학 내재적 동기의 영향력과 조절효과를 검증하였다. 연구 결과, 수학 내재적 동기의 수준에 따라, 수학 내재적 동기가 높은 집단에서 교사의 성취압력은 수학 학업성취도에 부적인 영향을 미치는 반면, 수학 내재적 동기 중 하집단에서는 교사의 성취압력이 수학 학업성취도에 정적인 영향을 미치는 것으로 나타났다. 부모의 성취압력은 수학 내재적 동기가 높은 집단과 낮은 집단 모두 수학 학업성취도에 정적인 영향을 미치고, 특히 수학 내재적 동기가 중 상인집단이 하집단에 비해 수학 학업성취도에 더 큰 효과를 나타냈다. 이러한 연구 결과를 바탕으로 교사와 부모의 성취압력을 통해 수학 학업성취도를 높일 수 있는 방안이 논의되었으며, 후속 연구를 위한 연구의 제한점을 제시하였다.

A study was conducted to establish the degree of genetic divergence between different hybrid forms and rearing conditions through estimation of the minimum number of genes (allelic pairs) differentiating parents in terms of specific quantitative traits. It was established that the minimum gene numbers differentiating parental lines in the inheritance of cocoon was 1, of cocoon shell weight- between 1 and 2, and of silk filament length- between 2 and 3. The variability in the specific genetic parameter could be explained by the reliability of the statistical-and-genetic method used and the expression of genes affecting the formation of each of the characters tested. Gene expression, in its turns is conditioned both by the gene interaction within the genotypes and the different genotype response to environmental change. To go deep in the problem, experiments should be conducted under strictly controlled conditions, reducing the mathematical-and-genetic analysis to a physiological levels and hence to analyse the genetic nature of the specific quantitative character formation and its genetic control.
