Using Decision Tree Analysis to Understand Foundation Science Student Performance. Insight Gained at One South African University

The Foundation Programme of the Centre for Science Access at the University of KwaZulu-Natal, South Africa provides access to tertiary science studies to educationally disadvantaged students who do not meet formal faculty entrance requirements. The low number of students proceeding from the programme into mainstream is of concern, particularly given the national imperative to increase participation and levels of performance in tertiary-level science. An attempt was made to understand foundation student performance in a campus of this university, with the view to identifying challenges and opportunities for remediation in the curriculum and processes of selection into the programme. A classification and regression tree analysis was used to identify which variables best described student performance. The explanatory variables included biographical and school-history data, performance in selection tests, and socio-economic data pertaining to their year in the programme. The results illustrate the prognostic reliability of the model used to select students, raise concerns about the inefficiency of school performance indicators as a measure of students' academic potential in the Foundation Programme, and highlight the importance of accommodation arrangements and financial support for student success in their access year.

Comparación entre dos modelos de educación bilingüe

Resumen

La presente investigación es una comparación entre dos modelos de educación bilingüe introducidos hace algunos años en el Colegio Alemán de Estocolmo: por un lado, estudiantes con el sueco como primera lengua de instrucción en el primer curso, con tres horas semanales de instrucción en alemán, que se iba incrementando progresivamente en los años posteriores, de manera que en el cuarto curso, el idioma en las clases era en un 50 por 100 alemán y en un 50 por 100 sueco. Por otro lado, estudiantes con tres horas semanales de instrucción en sueco en el primer curso, que aumentaban a cinco horas en los siguientes cursos.

Sólo se encontró un bilingüismo balanceado en los estudiantes que siguieron el currículum en alemán. Los estudiantes que siguieron el currículum sueco, mantuvieron el sueco como su idioma claramente dominante y obtuvieron una alta competencia en el alemán como segundo idioma.

Estas diferencias se explicaron por el bagaje lingüístico de los alumnos. Puesto que los alumnos que tenían el alemán como primera lengua adquirían sus dos lenguajes tanto en los entornos informales como en el formal, conseguían más input de los entornos naturales. Los estudiantes de idioma sueco en cambio, recibían el input del alemán únicamente en la instrucción formal de la escuela, que no podía compensar la fuerte influencia del idioma del hogar y del país.

Además, la presente investigación ha contribuido a corroborar la hipótesis de la edad óptima para el aprendizaje de la segunda lengua.     

Associations Between First‐Time Expectant Women's Representations of Attachment and Their Physiological Reactivity to Infant Cry

Associations among 53 primiparous women's Adult Attachment Interview classifications (secure–autonomous vs. insecure–dismissing) and physiological and self‐reported responses to infant crying were explored. Heart rate, skin conductance levels, and respiratory sinus arrhythmia (RSA) were recorded continuously. In response to the cry, secure–autonomous women demonstrated RSA declines, consistent with approach‐oriented responses. Insecure–dismissing women displayed RSA and electrodermal increases, consistent with behavioral inhibition. Furthermore, insecure–dismissing women rated the cries as more aversive than secure–autonomous women. Nine months postpartum, secure–autonomous women, who prenatally manifested an approach‐oriented response to the unfamiliar cry stimulus, were observed as more sensitive when responding to their own distressed infant, whereas women classified prenatally as insecure–dismissing were observed as less sensitive with their own infants.     

An evaluation of local teacher support strategies for the implementation of inquiry-based science education in French primary schools

This article presents the results of an evaluation of local teacher support strategies for implementing inquiry-based science education (IBSE) in French primary schools. The research objective was to determine which aspects of the French model of IBSE are implemented in class, and the efficiency of each teacher support strategy. Data were recovered through class observations. Findings confirm the need for long and continuous forms of teacher support, and expose the advantages and disadvantages of support delivered by pedagogues and support delivered by university science students. Writing in science class, which isa fundamental aspect of the French IBSE programme, is far from being implemented according to advocated practices.     

University of Cincinnati Medical Center: integrating information

The University of Cincinnati Medical Center has combined five existing units into a new organization responsible for initiating an Integrated Academic Information Management System (IAIMS). This new organization, Medical Center Information and Communications, was reorganized into nine departments, which now provide a variety of information services. Ultimate goals for IAIMS include a patient-centered database, a decision-support system, and a knowledge network. The IAIMS prototype, currently under development for the University of Cincinnati Hospital's Internal Medicine Service, consists of components representative of the IAIMS model's ultimate goals. A major premise of this IAIMS effort is that it is patient-centered.
