Fostering topic knowledge: essential for academic writing

Several researchers emphasize the role of the writer’s topic knowledge for writing. In academic writing topic knowledge is often constructed by studying source texts. One possibility to support that essential phase of the writing process is to provide interactive learning questions which facilitate the construction of an adequate situation model by initiating macro-strategies. In order to examine whether the provision of interactive learning questions during studying source texts leads to better results in academic writing both writing process and performance of a group supported by interactive learning questions was compared to a study-only group which read the source texts without learning questions. Results revealed that students provided with interactive learning questions wrote longer essays and spend significantly more time prewriting and writing/revising their essays than did the students of the study-only group. Studying source texts with learning questions resulted in text products of better readability and partly better accuracy and coverage of content. These findings suggest that engaging students in answering learning questions when reading source texts can positively affect both writing process and performance.     

The 2-MEV model: Constancy of adolescent environmental values within an 8-year time frame

The 2-MEV model is a widely used tool to monitor children's environmental perception by scoring individual values. Although the scale's validity has been confirmed repeatedly and independently as well as the scale is in usage within more than two dozen language units all over the world, longitudinal properties still need clarification. The purpose of the present study therefore was to validate the 2-MEV scale based on a large data basis of 10,676 children collected over an eight-year period. Cohorts of three different US states contributed to the sample by responding to a paper-and-pencil questionnaire within their pre-test initiatives in the context of field center programs. Since we used only the pre-program 2-MEV scale results (which is before participation in education programs), the data were clearly unspoiled by any follow-up interventions. The purpose of analysis was fourfold: First, to test and confirm the hypothesized factorized structure for the large data set and for the subsample of each of the three states. Second, to analyze the scoring pattern across the eight years’ time range for both preservation and utilitarian preferences. Third, to investigate any age effects in the extracted factors. Finally, to extract suitable recommendations for educational implementation efforts.     

Integrating educational institutions to produce intellectual capital for sustainability in Caguas,Puerto Rico

This research is part of a broader investigation to analyse the processes followed by the Caguas Municipality at the Commonwealth of Puerto Rico in an effort to develop the characteristics of a ‘Smart City’ as an example of sustainable development. We describe the integration of the educational institutions’ initiatives and the municipal government strategic plan to contribute to the knowledge and intellectual capital that brings sustainability to the city. An actor's model was designed to represent this integration. The conceptual framework was based on the concepts of knowledge production and sharing as applied to the collaboration between critical representative actors. Field research consisting of in-depth interviews was performed to ascertain the integration processes and their relationship with such processes of knowledge production and sharing. The results showed that the governance paradigm implemented is already empowering the citizens to contribute with intellectual capital that brings sustainability to Caguas.     

Explaining as Mediated Action

Explaining is one of the most important everyday practices in science education. In this article, we examine how scientific explanations could serve as cultural tools for members of a group of pre-service physics teachers. Specifically, we aim at their use of explanations about forces of inertia in non-inertial frames of reference. A basic assumption of our study is that explanatory tools (e.g., typical explanations learned) shape the ways we think and speak about the world. Drawing on the theory of mediated action, analysis illustrates three major claims on scientific explanations: (1) explaining is an act of actively responding to explanations presented by others (and not only to evidence itself); (2) the actual experience of explaining involves the enactment of power and authority; (3) resistance (not acknowledging an explanation as one’s own) might be a constitutive part of learning how to explain (hence, teachers could approach scientific explanation in a less dogmatic way). These assertions expand the possibilities of dialogue between studies of scientific explanations and the social sciences. Implications for science teaching and research in science education are presented.     

Supplementation of urban home visitation with a series of group meetings for parents and infants: results of a "real-world" randomized, controlled trial

OBJECTIVE: Home visitation has been shown to be effective in reducing rates of child maltreatment and in enhancing psychosocial outcomes in children and their parents. Even when available, however, it is underutilized by parents in some urban settings. We tested a supplemental 10-session group intervention for its ability to increase active participation in home visitation, enhance the quality of caregiving behavior of parents, and improve social developmental outcome in children. METHOD: A randomized controlled design was utilized, involving two separate cohorts of parents of 3- to 18-month old infants, totaling 148 parent-child dyads. The intervention focused on practical experience in promoting parent-infant attachment relationships. RESULTS: At 6 months follow-up, there was a substantial increase in the proportion of intervention group parents participating in home visitation, compared to parents in the control group (Fisher's exact p = .008). Parents in the intervention group exhibited a trend for improvement in their capacity to appropriately interpret infants' emotional cues (p = .08), independent of the effects of home visitation itself. Attrition in both the treatment and control groups was inversely associated with income and level of education. CONCLUSIONS: Group meetings may constitute an effective means of engaging stressed urban families in home visitation.     

Declining Gaze to Faces in Infants Developing Autism Spectrum Disorder: Evidence From Two Independent Cohorts

Two independent cohorts (N = 155, N = 126) of infants at high and low risk for autism spectrum disorder (ASD) were followed prospectively between 6 and 36 months of age, when n = 46 were diagnosed with ASD. Gaze to adult faces was coded—during a developmental assessment (Cohort 1) or a play interaction (Cohort 2). Across both cohorts, most children developing ASD showed sharp declines in gaze to faces over time, relative to children without ASD. These findings suggest that declining developmental trajectories may be more common than previously recognized by retrospective methods. Trajectory-based screening methods could potentially identify children in the early stages of symptom onset and allow for early intervention before the full disorder has developed.     

A study of students’ reasoning about probabilistic causality: Implications for understanding complex systems and for instructional design

Understanding complex systems requires reasoning about causal relationships that behave or appear to behave probabilistically. Features such as distributed agency, large spatial scales, and time delays obscure co-variation relationships and complex interactions can result in non-deterministic relationships between causes and effects that are best understood statistically. Causal Bayesian Research (e.g. Gopnik and Schulz in Causal learning: psychology, philosophy, and computation, Oxford University Press, New York, 2007) suggests that summing across probabilistic instances is inherent to human causal induction, yet other research (e.g. Schulz and Sommerville in Child Development 77(2):427–442, 2006) suggests a human tendency to assume deterministic relationships. Classroom science learning often stresses the replicability of outcomes, putting this learning in tension with understanding probabilistic patterns in complex systems. This investigation examined students’ reasoning patterns on tasks with probabilistic causal features. Microgenetic studies were conducted in multiple sessions over a school year with students in kindergarten, second, fourth and sixth grades (n = 16) to assess their assumptions when dealing with tasks from four domains: social; games; machines; and biology. Later sessions attempted to scaffold students’ understanding using connection making and analogical reasoning. This paper reports on the overall patterns and trends in the data. Most students held a deterministic stance at the outset; however, at least one student at each grade level reasoned probabilistically from the start. All students except one eventually revealed at least one topic for which they held a primarily probabilistic stance. The results have implications for how students reason about complex systems and for how patterns of co-variation and evidence in science are discussed.     

Social Work in Higher Education: Internships in Opportunity Programs

ABSTRACT

Field education is essential to the development of professional social workers. Despite the significant overlap in social work’s and higher education’s missions and values, there is a scarcity of social work internships specifically in higher education settings. The placement of social work interns in institutions of higher education provides a setting where they can develop new knowledge and skills and increase their capacity to support college students toward academic success. This conceptual article discusses the role of social work in higher education and provides a model social work internship in an opportunity program, including its creation, development, challenges, outcomes, and future direction.     

Perception and Use of YouTube by Music Lecturers and Librarians in Selected Tertiary Institutions in Kwara State,Nigeria

This study examined the music lecturers and librarians use and perception of YouTube in selected Kwara State tertiary institutions. Survey approach was adopted to conduct the study. The sample comprised 35 respondents (20 librarians and 15 music lecturers). Three research questions were answered while data were analyzed using percentage, frequency count, and cross tabulation. YouTube was used by the music lecturers mostly for teaching, research and learning, enhancing learning experience, and engaging students with the contents of music lessons. Librarians on the other hand use YouTube mostly as reference point for events and occurrences, teaching tool for library instruction; and for communicating other libraries.
