The association between financial aid availability and the college dropout rates in Colombia

The main objective of this study is to estimate the association between financial aid and college dropout rates of postsecondary students in Colombia. We use a unique dataset from the Colombian Ministry of Education that includes all enrolled college students in the country between 1998 and 2008. Logistic regression is used to identify the correlation between receiving different forms of financial aid on the dropout rates of the students. The main results of the study suggest that the probability of dropping out decrease between 25 and 29% according to the type of financial aid received. There is also evidence that the financial aid is more effective in reducing dropout rates at the beginning of the student’s college careers. This result holds after controlling by type of postsecondary institution attended. These findings suggest that financial aid is an effective tool to reduce dropout rates, and therefore increase persistence and expand access in Colombia.     

Exclusory and transformative dimensions of adult environmental education in two Brazilian protected areas

This study addresses the limitations and potential for the development of an adult environmental education program in two protected areas in Brazil. The investigation was based on critical communicative methodology and involved 25 people variously related to puma conservation and environmental education. We found that the staff of protected areas had difficulties interacting with the local community. The main cited obstacle was the lack of infrastructure and staff, but partnerships with scientists and other institutions might help to overcome this limitation. As we identified a great diversity of potential audience, a dialogical process would be necessary to collectively identify community demands and seek solutions. Moreover, an adult environmental education program must consider the characteristics of adulthood and should promote diverse types of activities. In conclusion, we suggest that dialogical learning and critical communicative methodology can contribute to the development of the adult environmental education.     

From Hamburg to Belem: the limits of technocratic thinking in adult learning education

This article discusses some of the generalized analyses of adult learning education, mostly informed by technocratic thinking, highlighting perceived trends in adult learning education between CONFINTEA V and CONFITEA VI. Those trends could be understood as challenges. Employing a political sociology of adult learning education as a critique of instrumental reason is advanced.     

The influence of the family educational scenario on internet use of primary and secondary school children / La influencia del escenario educativo familiar en el uso de internet en los niños de primaria y secundaria

Abstract

With the aim of studying the impact of the internet in the home, this paper analyses how the physical component (where and with whom) and attitudinal component (who decides what the child is to see on the internet and motivations for internet use) of the family educational scenario influence the frequency of internet use and diversity of uses, as reported by parents. The participants included 711 parents of children in primary and secondary school. Results showed that being in secondary school, using the internet in privacy at home, without company, internet content under the child’s control, and parental motivations based on the internet being used as a means for the child to relax, predicted higher frequency of internet use. Some of these factors, as well as the presence of peers and new parental attitudes related to the use of the internet for social and learning purposes, predicted a greater variety of uses, suggesting a more appropriate family scenario. The practical implications for parental education on this matter are described.     

Teacher Satisfaction and Turnover in Charter Schools: Examining the Variations and Possibilities for Collective Bargaining in State Laws

Charter schools see as many as one in four teachers leave annually, and recent evidence attributes much of this turnover to provisions affected by collective bargaining processes and state laws such as salary, benefits, job security, and working hours. There have been many recent efforts to improve teacher voice in charter schools (Kahlenberg & Potter, 2014), including engaging in some form of collective bargaining, but we know little about the possibilities dictated by state laws. Therefore, this article describes the possibilities and variations for collective bargaining by state and for different charter types (e.g., conversion vs. newly created charters), as well as laws that have the potential to improve teacher satisfaction in charter schools. Ideally, state laws and the collective bargaining process should provide the appropriate balance between flexibility for charter school leaders, teacher voice, and protections for teachers.     

Browse and Search Patterns in a Digital Image Database

A prototype image retrieval system with browse and search capabilities was developed to investigate patterns of searching a collection of digital visual images, as well as factors, such as image size, resolution, and download speed, which affect browsing. The subject populations were art history specialists and non-specialists. Through focus group interviews, a controlled test, post-test interviews and an online survey, data was gathered to compare preferences and actual patterns of use in browsing and searching. While specialists preferred direct search to browsing, and generalists used browsing as their preferred mode, both user groups found each mode to play a role depending on information need, and found value in a system combining both browse and direct search. There were no significant differences in performance among the search modes of browse, search, and combined browse/search models when the quasi-controlled study tested the different modes.

An agentive focus may limit learning about complex causality and systems dynamics: A study of seventh graders' explanations of ecosystems

Agent-oriented pedagogies have been used in teaching concepts related to complex systems dynamics. However, little research has systematically explored the role of a strong agency-oriented focus on understanding of complex, dynamic ecological systems. This study analyzed seventh graders' (n = 216) explanations of a complex ecological scenario. The findings show that students were more likely to generate agentive than nonagentive explanations and students who adopted an agentive framing were least likely to understand the complex causal dynamics of two environmental scenarios, eutrophication in a pond and acid rain in a forest. Furthermore, students' initial inclination toward agency-oriented explanation on the assessment was predictive of their performance on a postassessment following an instructional opportunity to learn about ecosystems dynamics; a strong agency orientation corresponded to less complex interpretations of the dynamics of the ecosystems. The results suggest that a strongly agentive perspective may limit students' ability to learn complex systems dynamics and that the pedagogical advantages of agent-based approaches may not be without limitations.
