Impact of a computer-based intervention in Chilean children at risk of manifesting reading difficulties / Impacto de una intervención basada en ordenador en niños chilenos con riesgo de manifestar dificultades lectoras

Reading difficulties have reached a prevalence of 3–10% in school-age children. Those who present these difficulties avoid reading and benefit very little from school-based learning opportunities, resulting in maladjustments, dropping out of school and having to repeat grades. Presented here are the results of an intervention based on a computer game intended for explicit phonic training in first-grade school children at risk of possessing reading difficulties. Fifty-six children from a low socioeconomic status (SES) and 31 children from a high socioeconomic status, divided into two groups (control and experimental), participated in the study. After the intervention, participants from the low-SES experimental group had enhanced their skills regarding letter sound recognition, whereas the high-SES experimental group had improved their naming speed. The results are discussed in light of the impact of interventions based on computer games and of the importance of the development of sublexical skills in children at risk of manifesting reading difficulties in transparent orthographies.     

Analyzing teaching quality in Botswana and South Africa

This study focuses on quantifying the quality of mathematics teaching in 183 randomly selected sixth grade classrooms: 100 from the North West province of South Africa and 83 from South East Botswana. The teaching quality is measured by coding videotaped lessons for three different components: mathematical proficiency, level of cognitive demand, and observed teacher knowledge. Results suggest that the overall teaching quality is about the same in both regions. Some variation was observed at the level of each component. For example, in the South Africa sample the students engage more in tasks that just involve “memorization” and less in tasks that involve “procedures without connections” in comparison with the Botswana students. Teachers in Botswana implement the official curriculum more faithfully than do those in North West. In both countries most of the learners engaged only in low-level tasks (very little activity involved “procedures with connections”) and teachers demonstrated a lack of knowledge about how to integrate mathematical content with effective pedagogical techniques.     

Incompatibility between pregnancy and educational projects,from the perspective of socially vulnerable adolescent women and men in Mexico

Research focused on adolescent pregnancy reports that this event acquires significance and has different consequences according to the context and social subjects who experience it. In this study, by means of a sample formed by adolescent women and men who are socially vulnerable in Mexico, with and without a history of pregnancy, we can see how this reproductive event turns into a factor of educational vulnerability and how their possibilities and expectations with respect to continuing in school are determined in a differentiated manner, according to gender. The findings show that adolescent pregnancy in vulnerable sectors is scarcely compatible with educational projects and that possibilities and expectations to continue in or re-enter the school system are determined by gender differences; these usually lead to fewer opportunities for adolescent women to return to school during or after pregnancy.     

An Integrated Knowledge Framework to Characterize and Scaffold Size and Scale Cognition (FS2C)

Size and scale cognition is a critical ability associated with reasoning with concepts in different disciplines of science, technology, engineering, and mathematics. As such, researchers and educators have identified the need for young learners and their educators to become scale-literate. Informed by developmental psychology literature and recent findings in nanoscale science and engineering education, we propose an integrated knowledge framework for characterizing and scaffolding size and scale cognition called the FS2C framework. Five ad hoc assessment tasks were designed informed by the FS2C framework with the goal of identifying participants' understandings of size and scale. Findings identified participants' difficulties to discern different sizes of microscale and nanoscale objects and a low level of sophistication on identifying scale worlds among participants. Results also identified that as bigger the difference between the sizes of the objects is, the more difficult was for participants to identify how many times an object is bigger or smaller than another one. Similarly, participants showed difficulties to estimate approximate sizes of sub-macroscopic objects as well as a difficulty for participants to estimate the size of very large objects. Participants' accurate location of objects on a logarithmic scale was also challenging.     

Unstable and multiple child care arrangements and young children's behavior

Growing evidence suggests that child care instability is associated with child behavior problems, but existing studies confound different types of instability; use small, convenience samples; and/or control insufficiently for selection into child care arrangements. This study uses survey and calendar data from the Fragile Families and Child Well-Being Study to estimate the associations between three different types of child care instability—long-term instability, multiplicity, and the use of back-up arrangements—and children's internalizing, externalizing, and prosocial behaviors at age 3, controlling for a large number of child and family background characteristics. Long-term instability between birth and age 3, as measured in both the survey and calendar data, is associated with higher levels of externalizing behavior problems. Current multiplicity at age 3 (as measured by survey data) is associated with higher levels of both externalizing and internalizing behavior problems, but stable multiplicity over time (as measured using calendar data) is not. Finally, the use of back-up arrangements at age 3 is associated with higher levels of internalizing behaviors. We find no consistent differences in these results by the timing of instability, child gender, family income, or type of care.

A Survey of Scholarly Literature Describing the Field of Bioinformatics Education and Bioinformatics Educational Research

Bioinformatics education can be broadly defined as the teaching and learning of the use of computer and information technology, along with mathematical and statistical analysis for gathering, storing, analyzing, interpreting, and integrating data to solve biological problems. The recent surge of genomics, proteomics, and structural biology in the potential advancement of research and development in complex biomedical systems has created a need for an educated workforce in bioinformatics. However, effectively integrating bioinformatics education through formal and informal educational settings has been a challenge due in part to its cross-disciplinary nature. In this article, we seek to provide an overview of the state of bioinformatics education. This article identifies: 1) current approaches of bioinformatics education at the undergraduate and graduate levels; 2) the most common concepts and skills being taught in bioinformatics education; 3) pedagogical approaches and methods of delivery for conveying bioinformatics concepts and skills; and 4) assessment results on the impact of these programs, approaches, and methods in students’ attitudes or learning. Based on these findings, it is our goal to describe the landscape of scholarly work in this area and, as a result, identify opportunities and challenges in bioinformatics education.     

Navigating OER: The Library’s Role in Bringing OER to Campus

In 2014, three librarians at the University of San Diego came together to explore open educational resources (OER). Coming from both technical services and digital collections, we were well-versed in the economic challenges facing today’s libraries. In order to formulate the approach that would work best for our campus, we first had to educate ourselves on the past, present, and possible future of the Open Access movement. While traditionally Open Access has focused on serials, OER offer the opportunity to expand its benefits to other formats. This article examines opportunities and tensions surrounding OER, as well as highlighting major players on the OER landscape. Our efforts began with a focus group for faculty to assess their own knowledge of and opinions on OER. After establishing a stipend budget, we sent out a call for proposals to faculty who were interested in participating in the Copley OER Initiative.     

Towards a new cartography of curriculum reform: Reflections on educational decentralization in Argentina

Curriculum reforms have led to discursive and organizational changes in Argentina. These reforms have reshaped school knowledge and institutional patterns of school administration. We analyse the process of this 'curriculum reterritorialization', the contradictions and displacements it produces, and the hybrid products that result from it. Reterritorialization is traced through four interrelated movements: the hybridization of discourses; the design of new maps of relations between the centre and the periphery of the educational system; the new 'regime of truth' that emerges out of these changes; and the role of the intellectual in educational reform. Although they are different in scope and magnitude, these movements provide the tools required to analyse the many ways in which curriculum reform is transforming Argentina's educational experiences.
