A Study of the Effects of a LSC Project on Scientists’ Teaching Practices and Beliefs

The purpose of this study was to examine the influence of a local systemic change (LSC) project on scientists’ practices and beliefs about teaching and learning. A mixed-method design was implemented that consisted of a series of interviews and the administration of the Classroom Learning Environment Survey (paper presented at the annual meeting of the National Association for Research in Science Teaching, Anaheim, CA, 1994). Results from this study suggest that collaborative opportunities afforded by this model program have positively influenced scientists’ beliefs about teaching elementary science and may be impacting some of the scientists’ pedagogical and curricular practices in their general education courses. Many scientists have developed new collaborative projects, all intended to improve science education at the graduate and undergraduate level, and are beginning to understand the complexity of science education reform.     

Fehlende Werte in sportwissenschaftlichen Untersuchungen

Missing values are a serious statistical problem in empirical studies which tends not to be considered in sport scientific studies. The methods usually applied such as listwise and pairwise deletion, mean and regression imputation do not constitute satisfactory solutions. New methods such as Maximum Likelihood Estimation (ML) and Multiple Imputation (MI) have not yet been widely implemented. The aim of this article is to change this situation. For this purpose, this article provides an overview of the missing data theory stated by Rubin (1976). Based on this approach, different methods for dealing with the problem of missing data will be presented and discussed. Special emphasis is put on new methods, in particular MI. In the past, the application of MI required special software. Since the implementation of MI in SPSS 17 (SPSS 2009) there is no obstacle for a routine usage of this method to handle missing data problems. The implementation of MI will be illustrated with an empirical study with a missing data mechanism typical for sport scientific studies. Using this example, advantages of MI as well as current limitations and practical difficulties will be discussed.     

A cross-cultural study of parents' perceptions of early childhood programs

Cross-cultural studies in early childhood education assist in expanding perspectives and gaining increased understanding and appreciation of programs in other countries. Because both Sweden and the United States are interested in parent involvement in early childhood programs, a survey was conducted to assess parent's perceptions of these programs. Following a review of family life and early childhood education in Sweden and the United States are the specific components of the cross-cultural study. A stratified random sample of parents whose children were involved in early childhood programs was done in St. Louis County, MN, United States, and Kronobergs Lan, Småland, Sweden. In the first section of the five-part survey, parents indicated the degree to which they agreed or disagreed with statements about such areas as governmental support of children and families. Parents in Sweden felt more support of the government, whereas parents in the United States used early childhood programs as a support mechanism to increase their confidence. In the other four sections of the survey, parents rated the importance of various types of parental involvement and the importance of various materials, activities, and caregiver actions in their children's programs. In general, parents in Sweden valued informal contact and inner-directed creative materials and activities. Parents in the United States valued more confining activities such as rote counting, community-based experiences, and compliance with adult expectations. The influence of the macro-society on parents' perceptions as well as microsystem interactions and environments is evident in this study. As early childhood educators learn about and adapt new ideas to their own programs, the potential of cross-cultural studies becomes realized in improved opportunities for young children and their families.     

Acknowledging Spanish and English resources during mathematical reasoning

As English-only efforts continue in the US schooling system, dual-language programs have served as attempts to preserve students’ home language. An after-school, dual-language, Spanish–English, mathematics program, Los Rayos was developed in a predominantly Mexican/Mexican–American neighborhood in Chicago. As participant observers with a sociocultural perspective, we explored the linguistic and personal resources used by participating 4th grade bilingual Latina/o students. We found that students used imaginative, playful, and hybrid linguistic resources to make sense of and solve probability tasks when engaged within a zone of mathematical practice. Results challenge narrow perspectives on bilingual students’ linguistic resources. Language implications are discussed.
