Science Teacher Education in Brazil: 1950–2000

This paper analyzes the most significant events occurring in Brazil’s educational, social and political areas over the last half century, viewed against a background of relevant worldwide events. The hypothesis presented here is that the relations between the country’s educational policies, the demands of the various segments of academia, and the public school system have always been strained. This strain has contributed positively to the evolution of academic knowledge and production, to the design of more modern curricular projects by institutional authorities, and to the initial recognition of the specific construction of school knowledge by the school system itself. However, the interaction of these major institutions lacks a crucial element—one that would lead to an effective change in the education of science teachers and produce a positive impact on Brazil’s schools—namely, the wholehearted participation of science teachers themselves. With this analysis, we intend to contribute by offering some perspectives and proposals for science teacher education in Brazil.     

Some controls control too much

Investigators of complex phenomena often seek to isolate variables of interest by statistical control. However, they run the risk of studying situations that do not exist in the real world, missing mediational links, and drawing incorrect policy conclusions. In the National Institute of Child Health and Human Development (NICHD) Early Child Care Research Network article in this issue, amount of time in child care was studied controlling for family income and maternal depression. However, use of child care is closely linked with maternal employment, which increases family income and decreases maternal depression, which in turn are linked to children's socioemotional adjustment. Hence, the negative effects of amount of time in child care reported in the article are likely overestimated relative to causal pathways in the lives of real families.     

Spanish and English Early Literacy Profiles of Preschool Latino English Language Learner Children

Research Findings: The purpose of this study was to examine within-group individual differences in the code-related and oral language abilities of an economically stressed Spanish-speaking English language learner (ELL) preschool sample and to evaluate the predictive relationship of these differences to later listening comprehension. Latent class analysis was used to identify similarities in both the latent and outcome variables to form classes of students with similar profiles on the measured variables. Our 1st finding confirmed the existence of 4 distinct psychometrically validated profiles: (a) Low English Language, Average Spanish Language, Mixed Spanish Code-Related (prevalence 19.4%); (b) Average English Language, Strengths in Spanish Language and Spanish Code-Related (24.2%); (c) Mixed English and Spanish Language, Low Spanish Code-Related (prevalence 34%); and (d) High English Language, Average Spanish Language, Mixed Spanish Code-Related (prevalence 22%). The resulting profiles demonstrated that English and Spanish code- and language-related domains of emergent literacy developed unevenly across the Spanish-speaking ELL preschoolers. Relative strengths and weaknesses in code- and language-related skills were also found to be meaningfully related to end-of-year listening comprehension—a precursor to reading comprehension. Finally, profiles yielded meaningful variability along sociodemographic variables. Practice or Policy: Implications, limitations, and directions for future research are discussed.     

Special Education: an overview of recent changes

Over the last two decades, there have been major changes in policy and practice in special education. Three theoretical models are outlined together with analysis of their underlying assumptions, effects on practice and implications for innovation and change. Finally, a brief discussion of new directions in the training of specialist teachers is presented.     

Myth and ceremony in financial decision making under stress: Case studies from Mexican universities

Based on case studies of a private and a public Mexican university, this research studied the economic strategies adopted by institutions of higher education to respond to financial stress. Rather than assuming that these strategies were selected primarily on the basis of their economic efficiency, the social processes that led to their adoption were explored.Economic development theory was employed to describe and conceptualize the universities' responses to financial difficulties. The concepts of institutional rules and rational myths in the environment and the processes that lead organizations to become similar to their environment were utilized to explore the role of the institutional environment on decision-making in times of fiscal uncertainty.Results indicate that financial stress was managed through economic measures, however the universities' institutional environment filtered and gave specific meaning to particular decision strategies. Institutional rules in the environment, acquiring the character of rationalized myths, pemeated and determined decision-making choices, and were evidenced in and sustained by mimetic, normative and coercive processes. In this light, the institutional environment pervaded and predicted rational decisions.     

Determinants of retention among Chicano college students: A structural model

This study tested a modified version of Tinto's student attrition model on a Chicano student population in two-year colleges. Structural equation modeling and LISREL VI were used to examine the parameter estimates of the structural and measurement models of the hypothesized causal model. Measures of goodness of fit were examined to provide indices for the overall fit of the causal model in the study. The measurement and structural models were found to represent a plausible causal model of student retention among Chicano students. Although the measures used in assessing the fit of the model reflected the overall strength of the hypothesized model, the present study was not entirely supportive of Tinto's model. The findings were only minimally supportive of the hypothesized relationship between measures of academic integration and retention. The results indicated that the hypothesized relationship between measures of social integration could not be substantiated. Moreover, measures of initial commitments were found to have a significantly large direct effect on the dependent variable, retention.     

Prevention of Targeted School Violence by Responding to Students' Psychosocial Crises: The NETWASS Program

The standardized, indicated school‐based prevention program “Networks Against School Shootings” combines a threat assessment approach with a general model of prevention of emergency situations in schools through early intervention in student psychosocial crises and training teachers to recognize warning signs of targeted school violence. An evaluation study in 98 German schools with 3,473 school staff participants (M_age = 46.2 years) used a quasi‐experimental comparison group design with three measurement points (pre, post, and 7 months followup) with schools randomly allocated to implementation conditions. The study found increases in teachers' expertise and evaluation skills, enhanced abilities to identify students experiencing a psychosocial crisis, and positive secondary effects (e.g., teacher–student interaction, feelings of safety).     

Legal implications of divorce and custody battles for day care administrators

The moment is tense ... and somewhat confusing. I am in my office with a small group of five-year-olds reading a story when Mrs. Wilson arrives. She is young, pretty, and looking very serious. “Billy says that his father visited here today!”     

The Competence Screening Questionnaire for Higher Education: Adaptable to the needs of a study programme

There is a lively discussion on how to evaluate competence-based higher education in both evaluation and competence research. The instruments used are often limited to course evaluation or specific competences, taking a rather narrow perspective. Furthermore, the instruments often comprise predetermined competences that cannot be adapted to higher education needs. The aim of this paper is to provide a flexible screening instrument into which practitioners/evaluators of study programmes can themselves insert the competences they are interested in, i.e. competences students ought to acquire through their study programme. The present study describes the development of the Competence Screening Questionnaire for Higher Education (CSQ-HE) in different domains of higher education. Results show that the CSQ-HE provides plausible screening information whilst fulfilling evaluation standards. It can be integrated into a higher education institution’s internal quality management system to demonstrate a programme’s legitimacy and enhance competence-based teaching and learning. Strengths, weaknesses and implications for practice are discussed.
