Pragmatism and Developmentalism in Brazilian Educational Thought in the 1950s/1960

This article proposes to analyse some aspects of the appropriation of New School thinking in Brazil, particularly Deweyan pragmatism, in the 1950s and 1960s. The analysis is based on the assumption that the developmentalist ideology that punctuated the debate on the economic, political and social restructuring of the country in these two decades constituted fertile ground for the return and expansion of pragmatist thinking amongst Brazilian educators, articulating itself, sometimes in contradictory ways, with this ideology. The focus of the analysis will be on the writings of the group of educators which circulated around the figure of Anísio Teixeira, at the time director of the National Institute for Pedagogic Studies (INEP), an organ linked to the Ministry of Education and Culture (MEC), which set itself the task of producing research that would support public policy in the field of education, as well as constituting itself as a center for teacher education and the stimulus and development of innovative experiences in the public school system. The appropriation of Deweyan pragmatism, in this context, had a triple perspective: pragmatism as scientific method, implying a specific conception of science, particularly the social sciences, with emphasis on the application of scientific knowledge in the solution of practical problems; as a way of democratic life; and as a synonym for experimentalism, in the sphere of schooling.     

Relational factors of vulnerability and protection for adolescent pregnancy: a cross-sectional comparative study of Portuguese pregnant and nonpregnant adolescents of low socioeconomic status

This study explores multiple relational contexts that promote vulnerability and protection against early pregnancy in a potential risk group of Portuguese adolescents. A comparative analysis was made between two groups of female adolescents of low socioeconomic status: pregnant adolescents (n=57) and adolescents without a history of pregnancy (n=81). Results suggest that several variables belonging to different contexts-family and school and peer relations--are important in the characterization of the two groups. Lower levels of mother's overprotection and father's emotional support, presence of early pregnancy in adolescent's mother, lower level of emotional proximity to peer relations, and higher number of school failures are significantly associated with adolescent pregnancy.     

Reducing bias in frequency judgment by improving source monitoring

A common finding in judgment and decision making is that people's frequency judgments often fail to map onto objective frequencies. The present research examined the possibility that one source of bias in frequency judgment is attributable to people's inability to screen out irrelevant memory traces. We used a two-list source-monitoring paradigm to investigate whether frequency judgments are influenced by "extra-experimental" experiences and whether enhancing source monitoring improves judgment accuracy. Across four experiments we found: (1) frequency judgments regarding one list were biased by the second, (2) manipulating encoding between lists improved source monitoring and resulted in more accurate judgments, (3) manipulating item context between lists improved source monitoring and resulted in more accurate judgments, but only when the context was item specific, and (4) manipulating simple-background context between lists was ineffective at improving source monitoring.     

Substance Use and Psychological Adjustment in Homeless Adolescents: A Test of Three Models

Three models of adolescent substance use, the deviance-prone, affect-regulation, and normative development models, were assessed regarding their ability to predict the substance use of a high-risk homeless adolescent sample with high rates of deviance, depression, and substance use. Hierarchical multiple regression analyses that included tests for curvilinear and gender interaction effects were performed. Results supported the deviance-prone model most strongly, with delinquency but not aggressive behavior predicting substance use. The affect-regulation model received support for females but not for males. With respect to the normative development model, results did not indicate that moderate substance users were better off than abstainers in terms of negative affect or interpersonal relationships.     

Parental Perceptions of Child Development Among Low-Income Mexican American Families

Parents' perceptions of child development are influenced by complex interactions among cultural, social, and economic factors. Insights into how parents from culturally diverse societies perceive the development of their children might explain why different cultural groups foster or value the development of different skills in their children. In this study, we explored the perceptions of child development among low income Mexican American parents. A series of ethnographic interviews were conducted with eight Mexican American families who had preschool children. Qualitative data analyses yielded three main themes that were important to these parents: family attitudes and values, changes, and adaptations. For these parents, the development of social attributes in children, that will enable them to function within their own cultural group, was as important as the development of cognitive or motor skills. Service providers, such as school and mental health personnel, should take into account cultural differences in parents' perceptions of the importance of various developmental milestones for their children when suggesting interventions typically used by parents in the dominant culture.     

The impact of school transitions: A focus for preventive efforts

The relationship between cumulative or single school transfers and a student's academic adjustment was explored. The school records of 250 high school students were examined and school transfers due to either residential mobility or the normative school change from eighth to ninth grade were identified. Correlations between the cumulative number of school transfers in a student's history and their ninth-grade academic performance and attendance record were computed for both ethnic and sex subgroups. Analyses of variance for repeated measures were performed to assess the impact of any single school transition occurring at different points in the child's development. Correlational analyses indicated that high rates of school mobility were significantly related to poor academic performance, particularly for black and Hispanic students. Analyses of variance revealed that while no single school transition due to residential mobility in Grades 1 through 8 had a significant impact on the student's posttransfer adjustment, the normative transition to high school was significantly related to lowered school performance and increased absences, particularly for students with a history of repeated school transfers and for black students.     

The Effects of Names on Perception of Intelligence, Popularity, and Competence

Three experiments were conducted to explore the effects of first names on judgments of intelligence, popularity, and competence. In Experiment 1, first names that were used more often in the past than they are now (called Older Generation names) were rated by a sample of college-aged judges as less popular and less intelligent than were first names that are used more often now than in the past (called Younger Generation names). In addition, male first names tended to have higher ratings of these same qualities than did female first names. In Experiments 2 and 3, either resumes or personal ads were used to provide additional information to the raters. Results similar to those found in Experiment 1 were obtained. In general the present experiment used groups of names rather than individual names so as to control for possible irrelevant and idiosyncratic differences that might be found among individual names. Relevance to research in which men and women are compared was discussed.     

Sentence comprehension and production in children with cochlear implants: Errorless procedures and equivalence-based instruction

Research supports equivalence-based instruction (EBI) and matrix training for increased listening and speaking skills in children with cochlear implants (CI). We incorporated errorless procedures to optimize the EBI and evaluated the effects on the auditory comprehension and verbal responding at-sentences level in six CI children who were readers and showed inaccurate tacting. Subject-verb-object sentences were arranged in two matrices; diagonal combinations were trained and evaluated non-diagonal combinations. EBI included stimulus fading and exclusion to directly teach the dictated sentence-picture matching; written-sentences construction upon dictation also was taught. Probes assessed the derived stimulus-stimulus and stimulus-response relations. All participants learned the auditory-visual discriminations and the exclusion resulted in fewer errors than on a stimulus fading procedure. Five participants formed equivalence classes and increased verbal responding to equivalent stimuli, especially pictures tacting. They also showed recombinative generalization for both matrices. Professionals can incorporate errorless procedures to EBI for improving sentence comprehension, tacting, and productivity in CI children.
