Why some early college high school students do not transition to a 4‐year college: An exploration of perceived barriers and schooling experiences on students’ transition plans

This study examined why some seniors attending Early College High Schools did not plan to continue their education at a 4‐year college immediately after graduation despite attending schools designed to provide coordinated academic and social supports with the expectation that all students would continue their education. Most students in our study (75%) did plan to continue their education at a 4‐year college immediately after graduation. For the remaining students, we used cluster analysis to identify four distinct groups of noncollege bound students. These groups were evaluated based on background characteristics, perceived opportunities and barriers, and schooling experiences. Results indicate that noncollege bound students are diverse in their reasons for not continuing their education at a 4‐year program and that any reform efforts designed to personalize opportunities and supports for these students must take into account how combinations of perceived opportunities and barriers shape their postsecondary decisions.     

The influence of gender,ethnicity and rurality upon perceptions of science

This paper reports an investigation into gender, ethnicity and rurality on Fijian students’ perceptions of science. A questionnaire was administered to a large sample of Form 5 classes. All students had completed a four year integrated "Basic Science" course in the junior secondary school and were continuing their studies in the upper secondary school. The responses were analysed to determine the significance of gender, ethnicity and rurality on the students’ perceptions of science, attitudes to science in the world and to science in the school curriculum. Specializations: gender issues and affective aspects of science and technology education. Specializations: Constructivism in science education, development education and gender issues.     

The temporal dimension of gender inequality in academia

This paper examines gender inequality in academic careers by applying Merton's concept of socially expected durations (SEDs). Women's relatively slower advancement along the academic hierarchy has been traditionally attributed to their traits and constraints. The concept of SED shifts attention from the individual to the organizational level, and the actual and expected augmented durations between promotions for women are viewed as part of the structural arrangements of academic institutions and their culture. It is argued that because of the distinct characteristics of academic careers, time-in-rank is an important dimension distinguishing among otherwise very uniform occupational roles and career patterns. The implications of conceptualizing career discrepancies in terms of socially expected durations are discussed.     

The academic "hurdle race": A case study

This study analyzes the career patterns of a cohort of faculty members in a large Israeli university and shows that women constitute a small minority in that university, and that their rank advancements are fewer, slower, and lower than men's. We examine three possible explaining mechanisms: (a) "Thresholds" - according to which after women cross a certain barrier, differential career development on the basis of gender disappears or is, at least, greatly reduced. (b) "Ceilings" - according to which women's advancement is curbed before they reach the highest rank. (c) "Hurdles" - according to which women, as compared to men, are confronted by more obtrusive barriers at each step of the academic career. We found that no threshold could be detected after which gender differences are reduced and that the ceiling effect may be a by-product of women's extended career paths. Rather, the analysis of the case study suggests that women's career trajectories are characterized by "hurdles", i.e., at each rank they stay longer and their advancement probability is lower than men's even when their publication rates are taken into account.     

Improving quantitative volumetric analysis skills in first year university chemistry courses

This paper describes a project in the School of Chemistry at The University of Melbourne. During 1992 thirty hours of videotapes were taken of students doing quantitative volumetric work in first year laboratories. These were viewed to find out what problems students encountered and what interactions they had with other students and with demonstrators. The data were logged on a Hypercard stack and novel visual images were produced to map student activity, both qualitatively and quantitatively. These data contributed to the design of a multimedia learning package which students worked through at the beginning of 1993. Video data of their laboratory performance after this intervention provides evidence of improved performance.

Women at the top: Female full professors in higher education in Israel

The perceptions and attitudes of women who have reached the top of the academic hierarchy (female full professors) are examined in reference to the effects of gender on their scientific work and career. The analyses refer to a number of issues such as encapsulation and isolation, opportunities and achievement. In general, female full professors do not feel that they have been discriminated against in the course of their careers. They are nevertheless aware of the different career patterns of the sexes in academia, with women having to work harder and longer than men to establish their suitability and competence as academic scientists. They do not however attribute these differences to sex-based stereotypes and discrimination, but rather to objective conditions and women's own decisions.This study was supported by a grant from the Ford Foundation received through the Israel Foundations Trustees.     

The Development of Hierarchical Representation of Two-Dimensional Space

Adults represent the location of a point in a 2-dimensional space using 2 independent dimensions. They encode location along these dimensions both at a fine-grained level and categorically. In reporting location, they combine and weight the fine-grained and categorical information. In Experiment 1, we found that children as young as 5 years use the same 2 independent dimensions in fine-grained spatial coding of location in a circle as are used by adults—radius and angle. However, categorical coding and hierarchical combination are seen only for radius, at both 5 and 7 years. The adult pattern, where angle as well as radius is coded hierarchically, emerges by 9 years. Experiment 2 shows that there is nothing intrinsically difficult about the categorical coding of angular information; when angle is the only dimension to be encoded, younger children use hierarchical coding. Changes in 2-dimensional hierarchical coding may be due to cognitive load factors and to changes in ability to assign frames of reference.
