Problems in the planning of higher education

With the growing demand for places in German universities, the present system of allowing entrance to everyone who holds the Abitur has become unsatisfactory. This paper looks at ways of controlling the size of the higher education system and allocating resources from the viewpoint of economic theory.Three ideal type educational planning models are sketched, one of which - a market model - is argued to have the greatest advantages. It would involve a state credit scheme for students with repayments via a graduate tax; student fees would provide all or most of the universities' funds. It would remove the inequity of the present system which involves a transfer of income from today's (relatively poorer) earners to tomorrow's, and from those with lower earning potential to those with higher. Since students would be in a position to choose the most satisfying and/or cheapest courses of study and would find it easier to change courses if they wished, it would reward cost-saving and student-satisfying innovation. By providing more finely graded levels of qualification within subject areas, it would reduce the extent to which jobs are ordered hierarchically in an irrational and inefficient way; and the universities would respond more flexibly to changes in labour market demands.This is a translation, with minor amendments, of a paper published in Fundamental Problems of Infrastructure Planning for Growing Economies, Proceedings of the Conference of the Society for Social Policy, Innsbruck, 1970, Berlin: Verlag von Duncker und Humblot, 1971.

Text Comprehension and Oral Language as Predictors of Word-Problem Solving: Insights into Word-Problem Solving as a Form of Text Comprehension

This study was designed to deepen insights on whether word-problem (WP) solving is a form of text comprehension (TC) and on the role of language in WPs. A sample of 325 second graders, representing high, average, and low reading and math performance, was assessed on (a) start-of-year TC, WP skill, language, nonlinguistic reasoning, working memory, and foundational skill (word identification, arithmetic) and (b) year-end WP solving, WP-language processing (understanding WP statements, without calculation demands), and calculations. Multivariate, multilevel path analysis, accounting for classroom and school effects, indicated that TC was a significant and comparably strong predictor of all outcomes. Start-of-year language was a significantly stronger predictor of both year-end WP outcomes than of calculations, whereas start-of-year arithmetic was a significantly stronger predictor of calculations than of either WP measure. Implications are discussed in terms of WP solving as a form of TC and a theoretically coordinated approach, focused on language, for addressing TC and WP-solving instruction.     

Intra-active entanglements: What posthuman and new materialist frameworks can offer the learning sciences

This paper examines what new materialist and posthumanist frameworks can offer learning science research in diverse maker learning environments. We explore what is gained by grappling with the entanglements between humans, non-humans and more-than-humans. To do this, we draw on Karen Barad's ethico-onto-epistemology and agential realism where she redefines connections to the shared world by attuning to the entangled matter that is created within intra-actions. We use this framework across four international cases: digital media camps, a university-level classroom-based makerspace, a Saturday outdoor makerspace workshop and a classroom-based museum makerspace. Each case study attends to how intra-actions enact agential forces in maker education research—forces that posthuman and new materialist frameworks help us see. In so doing, these case studies challenge many of the assumptions prevalent in the learning sciences about mattering and its implications in research sites.     

Enhancing Career Development Through the Career Success Club

The career development of students, demonstrated by students performing appropriate career developmental tasks, is important to institutions of higher education because career developed students are more likely to have career objectives, persist in their academic goals, gain career-related work experience, find employment in their chosen fields, and graduate. The purpose of this study was to determine if the career development of students by class level had been enhanced by participation in a career management plan specifically prepared for undergraduates. The intervention of a career management plan (i.e., the Career Success Club) was successful, especially for seniors and middles, in enhancing the career development of undergraduates. Career management plans may help students that are academically undecided to become more connected to their majors by focusing more on academic and career matters.     

On Kristjánsson on Aristotelian character education

I pursue three of the many lines of thought that were raised in my mind by Kristjánsson’s engaging book. In the first section, I try to get clearer on what exactly Aristotelian character education (ACE) is, and suggest areas where I hope the view is developed in more detail. In the second and longest section, I draw some lessons from social psychology about the pervasive role of what I call ‘Surprising Dispositions,’ and invite Kristjánsson to take up the difficult challenge of clarifying how ACE would help to address their influence on our thought and action. Finally, in section three I consider whether there is any robust empirical support for ACE, and if not, where that leaves us.     

A Reconsideration of Cognitive Load Theory

Cognitive load theory has been very influential in educational psychology during the last decade in providing guidelines for instructional design. Whereas numerous empirical studies have used it as a theoretical framework, a closer analysis reveals some fundamental conceptual problems within the theory. Various generalizations of empirical findings become questionable because the theory allows different and contradicting possibilities to explain some empirical results. The article investigates these theoretical problems by analyzing the conceptual distinctions between different kinds of cognitive load. It emphasizes that reduction of cognitive load can sometimes impair learning rather than enhancing it. Cognitive load theory is reconsidered both from the perspective of Vygotski’s concept of the zone of proximal development and from the perspective of research on implicit learning. Task performance and learning are considered as related, but nevertheless fundamentally different processes. Conclusions are drawn for the further development of the theory as well as for empirical research and instructional practice.

A practical approach for applying online remote experiments: OnPReX

The development of Internet technologies stimulates the increase of online technology-supported education in universities. Online learning based on remote experiments is capable of diminishing the scantiness in practical courses. In this paper, we present online practical courses based on remote experiments (OnPReX). These courses consist of online experiments, interactive graphics and an online tutoring-system organised at the Berlin Institute of Technology (TUB). We developed two online practical courses, one focusing on classical and the other on modern physics, for bachelor and intermediate diploma engineering students. Our online practical courses based on remote experiments took place in two test phases during two semesters. These courses were evaluated and the results were used to improve the courses. Our online practical courses on remote experiments have successfully been integrated as electives at the TUB.     

Exploring dynamic assessment as a means of identifying children at risk of developing comprehension difficulties

In this study, the authors explore a newly constructed dynamic assessment (DA) intended to tap inference-making skills that they hypothesize will be predictive of future comprehension performance. The authors administered the test to 100 second-grade children using a dynamic format to consider the concurrent validity of the measure. The dynamic portion of the assessment comprised teaching children to be "reading detectives" by using textual clues to solve what was happening in the story. During the DA children listened to short passages and answered three inferential questions (i.e., one setting, two causal). If children were unable to answer a question, they were reminded what a reading detective would do and given a set of increasingly concrete prompts and clues to orient them to the relevant portion of text until they could answer the question correctly. Results showed that the DA correlated significantly with a standardized measure of reading comprehension and explained a small but significant amount of unique variance in reading comprehension above and beyond vocabulary and word identification skills. In addition, results suggest that DA may be better than the standardized measure of reading comprehension at identifying intraindividual differences in young children's reading abilities.     

Antecedents of Norwegian beginning teachers’ turnover intentions

This study aims at exploring several individual, organizational, and contextual factors that may affect beginning teachers’ turnover intentions during their first years of practice. The sample consists of 227 beginning teachers (69% female and 31% male) from 133 schools in Norway. The results show four important antecedents of beginning teachers’ turnover intentions: collective teacher efficacy, teacher–principal trust, role conflict, and affective commitment. Our findings suggest that organizational and contextual factors, and not necessarily individual competence perceptions, have a significant impact on beginning teachers’ turnover intentions. Also the findings suggest that beginning teachers should be studied separately from more experienced teachers. Implications for school leadership are discussed.     

Microfluidic platform for separation and extraction of plasma from whole blood using dielectrophoresis

Microfluidic based blood plasma extraction is a fundamental necessity that will facilitate many future lab-on-a-chip based point-of-care diagnostic systems. However, current approaches for providing this analyte are hampered by the requirement to provide external pumping or dilution of blood, which result in low effective yield, lower concentration of target constituents, and complicated functionality. This paper presents a capillary-driven, dielectrophoresis-enabled microfluidic system capable of separating and extracting cell-free plasma from small amounts of whole human blood. This process takes place directly on-chip, and without the requirement of dilution, thus eliminating the prerequisite of pre-processed blood samples and external liquid handling systems. The microfluidic chip takes advantage of a capillary pump for driving whole blood through the main channel and a cross flow filtration system for extracting plasma from whole blood. This filter is actively unblocked through negative dielectrophoresis forces, dramatically enhancing the volume of extracted plasma. Experiments using whole human blood yield volumes of around 180 nl of cell-free, undiluted plasma. We believe that implementation of various integrated biosensing techniques into this plasma extraction system could enable multiplexed detection of various biomarkers.
