The End of Public Schools? Or a New Beginning?

Abstract

Public education is becoming increasingly privatized as private philanthropic organizations, such as the Bill & Melinda Gates Foundation, and corporations, such as Pearson, dominate the policy-making process, and more students enroll in publicly funded but privately administered charter schools. The privatization of education results from the dominance of neoliberal ideals promoting market competition, individualism, and standardized testing. In response, we call for replacing neoliberalism with social democratic policies emphasizing community, trust, and democratic deliberation.     

Making connections among multiple visual representations: how do sense-making skills and perceptual fluency relate to learning of chemistry knowledge?

To learn content knowledge in science, technology, engineering, and math domains, students need to make connections among visual representations. This article considers two kinds of connection-making skills: (1) sense-making skills that allow students to verbally explain mappings among representations and (2) perceptual fluency in connection making that allows students to fast and effortlessly use perceptual features to make connections among representations. These different connection-making skills are acquired via different types of learning processes. Therefore, they require different types of instructional support: sense-making activities and fluency-building activities. Because separate lines of research have focused either on sense-making skills or on perceptual fluency, we know little about how these connection-making skills interact when students learn domain knowledge. This article describes two experiments that address this question in the context of undergraduate chemistry learning. In Experiment 1, 95 students were randomly assigned to four conditions that varied whether or not students received sense-making activities and fluency-building activities. In Experiment 2, 101 students were randomly assigned to five conditions that varied whether or not and in which sequence students received sense-making and fluency-building activities. Results show advantages for sense-making and fluency-building activities compared to the control condition only for students with high prior chemistry knowledge. These findings provide new insights into potential boundary conditions for the effectiveness of different types of instructional activities that support students in making connections among multiple visual representations.     

The training of researchers in mathematics education — Results from an international survey

In this report we present the results of an international research study on the training of researchers in mathematics education. the study was carried out by some members of the international study group on theory of mathematics education. the research involved developing a questionnaire which was mailed to numerous institutions all over the world and the analysis of the answers which were received. the main objective of the study was to collect international data about the training of researchers in mathematics education and to establish an information network about graduate programs in the field. a total of about 150 questionnaires were sent out and 78 answers received. fifteen of these answers came from universities that wish to participate in the network although they do not have a program at present.Deceased.

Conditions for the Effectiveness of Multiple Visual Representations in Enhancing STEM Learning

Visual representations play a critical role in enhancing science, technology, engineering, and mathematics (STEM) learning. Educational psychology research shows that adding visual representations to text can enhance students’ learning of content knowledge, compared to text-only. But should students learn with a single type of visual representation or with multiple different types of visual representations? This article addresses this question from the perspective of the representation dilemma, namely that students often learn content they do not yet understand from representations they do not yet understand. To benefit from visual representations, students therefore need representational competencies, that is, knowledge about how visual representations depict information about the content. This article reviews literature on representational competencies involved in students’ learning of content knowledge. Building on this review, this article analyzes how the number of visual representations affects the role these representational competencies play during students’ learning of content knowledge. To this end, the article compares two common scenarios: text plus a single type of visual representations (T+SV) and text plus multiple types of visual representations (T+MV). The comparison yields seven hypotheses that describe under which conditions T+MV scenarios are more effective than T+SV scenarios. Finally, the article reviews empirical evidence for each hypothesis and discusses open questions about the representation dilemma.     

Transition to child care: associations with infant-mother attachment, infant negative emotion, and cortisol elevations

Seventy 15-month-old infants were studied at home before starting child care, during adaptation (mothers present) and separation (first 9 days without mothers) phases, and 5 months later. Security of infant-mother attachment was assessed before and 3 months after child care began. In the separation phase, salivary cortisol rose over the first 60 min following the mothers' departures to levels that were 75% to 100% higher than at home. Compared with insecure infants, secure infants had markedly lower cortisol levels during the adaptation phase and higher fuss and cry levels during the separation phase, and their fuss and cry levels were significantly correlated with their cortisol levels. Attachments remained secure or became secure if mothers spent more days adapting their children to child care.     

Is the Europe of Knowledge the talk of the town? Exploring how members of the European Parliament refer to higher education

While the European Parliament is increasingly involved in EU governance, its role in policy developments in domains of strategic importance for the EU has not been the focus of many studies. In this article, we analyse a new digital dataset containing more than 10,000 speeches delivered in the European Parliament plenary between 1999 and 2014 and identify patterns related to temporal increase or decrease in the Parliament's focus on higher education, the topics linked to higher education discussions and patterns concerning the country and party group affiliation of the European Parliament members who speak about higher education. Our findings suggest that the total number of speeches, either specifically dedicated to higher education, or mentioning higher education when addressing other issues, did increase over time and particularly during the adoption of action programmes and related budgetary decision. Furthermore, higher education was less referred to in the Parliament speeches as a stand‐alone issue than in relation to other policy areas in which the EU has strong jurisdiction. Finally, our findings indicate that the variance in whether a Member of the European Parliament speaks about higher education is more closely linked to country of origin than party affiliation, highlighting the persistent national dimension of higher education discussions at the European level. These findings attest to the increasing – yet largely overlooked – role of the European Parliament in higher education policy making.     

Health care, information needs, and outreach: reaching Ohio's rural citizens

As a rural state, Ohio has a vital interest in addressing rural health and information needs. NetWellness is a Web-based consumer health information service that focuses on the needs of the residents of Ohio. Health sciences faculty from the state's three Carnegie Research I universities--University of Cincinnati, Case Western Reserve University, and The Ohio State University--create and evaluate content and provide Ask an Expert service to all visitors. Through partnerships at the state and local levels, involving public, private, commercial, and noncommercial organizations, NetWellness has grown from a regional demonstration project in 1995 to a key statewide service. Collaboration with public libraries, complemented by alliances with kindergarten through twelfth grade agencies, makes NetWellness Ohio's essential health information resource.     

Acquisition,Preference and Follow-up Comparison Across Three AAC Modalities Taught to Two Children with Autism Spectrum Disorder

Identifying an augmentative and alternative communication (AAC) method for children with autism spectrum disorder (ASD) might be informed by comparing their performance with, and preference for, a range of communication modalities. Towards this end, the present study involved two children with ASD who were taught to request the continuation of toy play by: (a) signing MORE, (b) exchanging a picture card representing MORE, and (c) touching a MORE symbol from the screen of a speech-generating device. The children were also given opportunities to choose among the three modalities to identify their preferred method of communication. Both children performed better with picture exchange and the speech-generating device than with manual signing, but had variable performance during follow-up. Both children more often chose the speech-generating device, suggesting a preference for that modality. We conclude that concurrent intervention across several communication methods can generate data to inform the selection of an AAC modality.
