Using centrality of concept maps as a measure of problem space states in computer-supported collaborative problem solving

Problem solving likely involves at least two broad stages, problem space representation and then problem solution (Newell and Simon, Human problem solving, 1972). The metric centrality that Freeman (Social Networks 1:215–239, 1978) implemented in social network analysis is offered here as a potential measure of both. This development research study applied centrality measures to reanalyze existing concept maps from a recent investigation (Engelmann and Hesse, Computer-Supported Collaborative Learning 5:299–319, 2010). Participants (N = 120) were randomly assigned to interdependent (i.e. hidden profiles) or non-interdependent conditions to work online in triads using CmapTools software to create a concept map in order to solve a problem scenario. The centrality values of these group-created concept maps agreed with the common relations count analysis used in that investigation and allowed for additional comparisons as well as analysis by multidimensional scaling. Specifically, the interdependent triad maps resembled the fully explicated problem space, while the non-interdependent triad maps mainly resembled the problem solution. The results demonstrate that centrality is a useful measure of knowledge structure contained in these team concept map artifacts that allows researchers to infer problem representation start and goal state transitions during problem solving.     

Blinded to science: gender differences in the effects of race,ethnicity, and socioeconomic status on academic and science attitudes among sixth graders

Little research has examined whether the effects of race or socioeconomic status (SES) on educational attitudes differ by gender, limiting knowledge of unique vulnerabilities occurring at the intersection of multiple social statuses. Using data from 182 sixth-graders, interactions between gender, race/ethnicity, and SES in predicting educational aspirations, persistence, views of science, and educational self-efficacy are examined. African American and Latino boys express more negative attitudes relative to (1) higher-SES boys, (2) White boys, and (3) girls of any race/ethnicity or level of SES. The intersection of multiple inequalities in education across the early life course is discussed.     

Evoking Knowledge and Information Awareness for Enhancing Computer-Supported Collaborative Problem Solving

Computer-supported collaboration by spatially distributed group members still involves interaction problems within the group. This article presents an empirical study investigating the question of whether computer-supported collaborative problem solving by spatially distributed group members can be fostered by evoking knowledge and information awareness, i.e., awareness of a group member with regard to both their fellow collaborators’ domain knowledge and information underlying this knowledge. The study (N = 30 triads) confirmed the efficiency of this approach by comparing (a) an experimental condition in which an environment for fostering knowledge and information awareness was provided and (b) a control condition without such an environment, with regard to communication and cooperation aspects, the quality of the group maps (needed for solving the problems), and the problem-solving performance.     

‘Now I am free’—education and human resource development in Eritrea: contradictions in the lives of Eritrean women in higher education

Human resource development as an objective of education policy in developing countries is increasingly narrowed down to its human capital component. In Eritrea, the objective of a highly centralized human resource development strategy is to produce human capital for the advancement of the nation. This instrumentalist view ignores the fact that education is not only related to one's position in a given society, but equally to the development of personal identity and new forms of agency on an individual level—thus potentially encompassing contradictions between the individual and the common good. This paper—based on the personal histories of a sample of female students at Asmara University—discusses these contradictions in terms of these women's acceptance of and resistance to the government's plan for them. It further argues that an education system geared predominantly towards the creation of human capital is bound to do so at the expense of social solidarity.     

Boys’ and girls’ educational choices in secondary education. The role of gender ideology

This study aims to explain why boys and girls in secondary education choose different educational tracks. We argue that adolescents internalise gender expectations as to what is “appropriate” male and female behaviour in their gender ideology. Gender ideology can affect educational choices by influencing (1) how adolescents evaluate their competence in certain subjects (competence beliefs), (2) what they find important in a future occupation (occupational values) and (3) what school subject they prefer right now (subject preferences). Longitudinal data collected among adolescents at age 15 and 16 (N = 1062) are used. Multinomial path models show that gender ideology shapes boys’ occupational values and subject preferences, whereas for girls it shapes their competence beliefs. Only for boys this leads to gender-stereotypical educational choices, however. Our results support the idea that gender expectations are stricter for boys than for girls and may prevent men from entering more feminine career tracks.

College students' willingness to terminate a pregnancy

403 male and 420 female Michigan State University undergraduate students responded to survey questions on their willingness to terminate a pregnancy. The number of students willing to terminate a pregnancy changed according to situational scenarios and general questions presented. While 96% opted to terminate a life-threatening tubal pregnancy, only 3% would do so in the case of a fetus of unwanted gender. Except for cases of incest and rape, respondents were 2.3 times more likely to terminate for biomedical than for psychosocial reasons. 89% were willing to terminate for incest and 82% for rape. The 75% who considered the fetus to be a child were less inclined to terminate than those who perceived otherwise. These findings paralleled those of other studies which found that attitudes toward abortion are not strongly linked to gender. Most respondents were able to weigh moral convictions against taxing situations when considering pregnancy termination.     

Cash incentives and turnover in center-based child care staff

The current study evaluates the Workforce INcentive Project (WIN), a programmatic effort to increase child care workforce stability in center- and home-based child care providers via the provision of bi-annual cash incentives based on educational attainment. Five hundred and thirteen center-based teaching staff (304 WIN and 209 comparison) and 167 center directors (93 WIN and 74 comparison) from 179 state-licensed child care centers (99 WIN and 80 comparison) participated in the study reported. Survival analyses were conducted to compare turnover rates between the WIN group and the comparison group over a 20-month period. All analyses controlled for participant satisfaction with employment, location (i.e., urban, suburban, and rural), and, where appropriate, hourly wages. Although WIN participation was generally associated with lower rates of turnover in center-based staff, when position type, educational attainment, experience in the field, and hourly wages were considered (separately and together), WIN's relationship with turnover varied widely for directors and teaching staff. Findings are discussed in terms of past research and future cash incentive programs.     

Moving Fiercely Linear Preservice Teachers into the Joys of Integrating Art in the Classroom: An Artist Residency in a University Early Childhood and Special Education Program

How can artist residencies for preservice teachers plant seeds for future classrooms? Teacher educators and a teaching artist describe a two-tiered residency in an early childhood and special education program that transformed preservice teachers' attitudes toward visual art and arts integration. Findings are based on teaching artist and instructor reflections as well as a qualitative analysis of student journal entries. Preservice teachers who had no prior art training and were resistant toward abstract painting began to enjoy it and appreciate the value of art for children's learning. They came to recognize visual art as a tool to support social development and children with special needs, understood the importance of process in children's art experiences, and considered ways to integrate art throughout the curriculum. We urge teacher educators and teaching artists to incorporate artist residencies into teacher education programs to prepare future teachers to integrate the arts into the classrooms of tomorrow.
