Development of knowledge about the use of cues to aid prospective retrieval

Retrieval cues can be used to help one remember to perform tasks in the future and to relocate objects in the environment. However, in both tasks there are requirements for a retrieval cue to be effective as a mnemonic aid. For example, the cue must be associated with the target item, but it must not be ambiguous, and it must be appropriately placed. 2 studies assessed children's ability to evaluate the communicative quality of retrieval cues. In Study 1, 5-9-year-old children and adults evaluated the potential effectiveness of cues to remind themselves. In Study 2, 4-9-year-olds evaluated the potential effectiveness of cues for relocating hidden objects. Patterns of results were similar in both studies: young children first learned that the retrieval cue should be associated with the target and should be encountered for retrieval to occur. However, children often overlooked problems with the potential informativeness of the cues, such as ambiguity, and did not anticipate that such cues might be misinterpreted in the future. Children's difficulty in estimating their information needs may be related to their difficulty in monitoring their current comprehension state.     

Identifying at‐risk preschoolers: The discriminant validity of the differential ability scales

The discriminant validity of the Upper Preschool Level of the Differential Ability Scales (DAS) was studied using 32 at‐risk preschoolers (females = 14, males = 18) with a mean age of 57.28 months (SD = 4.43) and 30 normal preschoolers (females = 13, males = 17) with a mean age of 56.40 months (SD = 6.46). The results indicated that the DAS was an excellent measure to use when trying to differentiate between at‐risk and normal preschoolers. The DAS could reliably identify, better than chance, whether a child was at‐risk or normal. Specifically, the General Conceptual Ability score was found to be approximately 77% accurate in correctly classifying at‐risk from normal preschoolers. In addition, the use of the DAS in an abbreviated format by selecting specific core and/or diagnostic subtests during the preschool screening process was strongly supported. © 1999 John Wiley & Sons, Inc.

Epistemic schemes and epistemic states. A study of mathematics convincement in elementary school classes

The paper introduces an interpretative framework that contains a characterization of epistemic schemes (constructs that are used to explain how class agents themselves are able to gain convincement in or promote convincement of mathematical statements) and epistemic states (a person’s internal states, such as convincement or certainty related to the person’s beliefs and to the schemes that explain them); a taxonomy for the epistemic schemes is also proposed. On the basis of the interpretative framework, an analysis is made of an excerpt of a regular elementary school class, a school level at which explicit mathematics reasoning rarely arises. The paper contends that teachers and students use schemes based on reasons in order to make mathematical statements credible, but that they also resort–perhaps unconsciously–to epistemic schemes that are governed by extra-rational considerations.     

论理想和信念及其在认识中的功能——主体认识结构中的非理性要素研究

理想和信念是与人的认识活动密切相关的精神现象。人们通常认为它们只同理性认识相联系,实际上它们是既同理性认识相联系,又同非理性认识相联系。经过理性思考而形成的理想、信念是理性的;未经过理性思考而盲目接受的理想、信念就是非理性的。     

Epistemic beliefs in action: Spontaneous reflections about knowledge and knowing during online information searching and their influence on learning

In the present study it was investigated whether high school students are spontaneously able to reflect epistemologically during online searching for information about a controversial topic. In addition, we examined whether activating epistemic beliefs is related to individual characteristics, such as prior knowledge of the topic and argumentative reasoning skill; also whether learning from the Web is influenced by epistemic beliefs in action and the ability to detect fallacies in arguments. The participants (N = 64) were students of Grade 13, who were asked to think aloud during navigation. Qualitative and quantitative analyses were performed. Findings reveal that most participants spontaneously activated beliefs about all four dimensions identified in the literature, that is, about the simplicity/complexity, certainty/uncertainty, justification, and source of knowledge, at different levels of sophistication. Most epistemic reflections were about the source of knowledge. Two patterns of contextualized epistemic beliefs emerged and significantly influenced learning from the Web, which was also affected by participants' ability to identify argumentative fallacies.

Deepening the Responsibility: A Social Epistemic Approach to the Ethics of Professional and Technical Writing

This article recommends strategies academics can use to contribute to an issue of great interest in industry: how best to define, measure, and achieve quality documentation. These strategies include contextualizing quality definitions, advocating the use of multiple quality measures, conducting research to identify specific heuristics for defining and measuring quality in particular workplace contexts, and partnering with industry to educate upper management about those heuristics and the benefits of promoting technical communicators to the strategic role of organizational “gatekeepers of quality.”     

Epistemic profiles and metacognition: support for the consistency hypothesis

Relations were examined between epistemic profiles, metacognition, problem solving, and achievement in the context of learning in an educational psychology course. Two hundred thirty-one university students completed self-report inventories reflecting their epistemic profiles and use of metacognitive strategies, and were epistemically profiled as rational, empirical, or both rational and empirical in their approaches to knowing. From the larger sample, 78 students participated in a problem-solving session using a think aloud protocol. Results demonstrated that for self-reported metacognitive strategies, students profiled as both rational and empirical had the highest frequency of metacognitive strategy use compared to students profiled as empirical. Similarly, during problem solving, students profiled as both rational and empirical had the highest frequency of regulation of cognition compared to students profiled as empirical or rational. Finally, students profiled as both rational and empirical attained higher levels of problem-solving achievement compared to students profiled as empirical.     

Universities and the market economy: The differential impact on knowledge production in sociology and economics

Based on the conceptualframework of Pierre Bourdieu, this studycompares the impact of pressure to develop tieswith non-academic organisations on two fieldsof research, namely: sociology and economics.The study highlights the dynamics particular toeach discipline and shows that a soundunderstanding of transformations affectinguniversity research cannot exclude analysis ofthe specificity of each one. Two cohorts ofprofessors were studied in two Quebecuniversities: the first cohort was made up ofprofessors who received tenure between 1974 and1983, and the second between 1989 and 1998. Theresults suggest that pressures in favor ofpartnership with non-academic organisationshave not had the same impact in sociology andeconomics. While research practices haveundergone transformations in each discipline,the nature of these transformations differs inan important way. The results also contradicttwo popular models in knowledge productionstudies, which are the Entrepreneurial Science,and Mode 1/Mode 2 models. Although these modelsclaim that academic research orientation hasbecome geared towards problem-solving, ourresults indicate, however, that the oppositetrend has been taking place in sociology andeconomics.     

Counting the nouns: simple structural cues to verb meaning

Two-year-olds use the sentence structures verbs appear in--subcategorization frames--to guide verb learning. This is syntactic bootstrapping. This study probed the developmental origins of this ability. The structure-mapping account proposes that children begin with a bias toward one-to-one mapping between nouns in sentences and participant roles in events. This account predicts that subcategorization frames should guide very early verb learning, if the number of nouns in the sentences is informative. In 3 experiments, one hundred and thirty-six 21- and 19-month-olds assigned appropriately different interpretations to novel verbs in transitive ("He's gorping him!") versus intransitive sentences ("He's gorping!") differing in their number of nouns. Thus, subcategorization frames guide verb interpretation in very young children. These findings constrain theoretical proposals about mechanisms for syntactic bootstrapping.     

Carl Hempel's Philosophy of Science: How to Avoid Epistemic Discontinuity and Pedagogical Pitfalls

Mathematical theories are essential for explanations in physics, chemistry andengineering. These theories often incorporate functions that are defined by theirrelation to other variables in the theory but not with reference to experimentalobservations. The wave function in quantum mechanics is perhaps one of thebest known example of such function, even though classical theories also providemany examples of such functions. These functions, which seem to hang in thin airdisconnected to experimental data, offer a daunting challenge to the instructor. Inthis article we consider the epistemic status of such functions and a method ofintroducing them to the students, a method that does not distort the original theory.We build our model for explanation on Hempel's analysis of relation between theoryand experiment and refine it further to show their roles in concept formation.     

Integrating the light and dark sides of student engagement using person-oriented and situation-specific approaches

This study contributes to the research on student engagement in three ways: 1) by combining questionnaire and situational measures of engagement using the Experience Sampling Method (ESM), 2) by applying a demands-resources model to describe the positive and negative aspects of student engagement, and 3) by adopting a person-oriented approach to describe subgroups of students with different profiles of engagement and burnout symptoms. Two studies were conducted: sample one comprised 255 US high school students (45.5% female, 9th – 12th grade), and sample two 188 Finnish comprehensive and high school students (59.6% female, 9th to 10th grade). Latent profile analyses (LPA) of person-level measures of schoolwork engagement and burnout in the US and Finland revealed four profiles: 1) engaged, 2) engaged-exhausted, 3) moderately burned out (risk for burnout) and 4) burned out. These four groups were identified in both samples, but differed in their prevalence. The groups differed in their state experiences of situational demands, resources and engagement at school. Engagement is not wholly an experience of ‘flourishing’: some students experienced elevated levels of both engagement and burnout. Thus, positive and negative aspects of engagement should be studied and modeled together.

Neoliberalism,higher education and the knowledge economy: from the free market to knowledge capitalism

The ascendancy of neoliberalism and the associated discourses of ‘new public management’, during the 1980s and 1990s has produced a fundamental shift in the way universities and other institutions of higher education have defined and justified their institutional existence. The traditional professional culture of open intellectual enquiry and debate has been replaced with a institutional stress on performativity, as evidenced by the emergence of an emphasis on measured outputs: on strategic planning, performance indicators, quality assurance measures and academic audits. This paper traces the links between neoliberalism and globalization on the one hand, and neoliberalism and the knowledge economy on the other. It maintains that in a global neoliberal environment, the role of higher education for the economy is seen by governments as having greater importance to the extent that higher education has become the new star ship in the policy fleet for governments around the world. Universities are seen as a key driver in the knowledge economy and as a consequence higher education institutions have been encouraged to develop links with industry and business in a series of new venture partnerships. The recognition of economic importance of higher education and the necessity for economic viability has seen initiatives to promote greater entrepreneurial skills as well as the development of new performative measures to enhance output and to establish and achieve targets. This paper attempts to document these trends at the level of both political philosophy and economic theory.     

从学科到学科群:知识分类体系和知识政策的视角

我国大学学科建设的重要性虽然已为大学举办者和管理者所认识,并采取了改革措施,但由于没有找到学科建设困境的真正原因——知识政策和知识分类,改革成效并不显著。知识分类体系已经具有了教育学意义,知识政策是学科分类体系的制度化体现,知识政策是造成大学学科发展困境的主要因素。知识分类体系下的知识生产模式已不能满足现代知识生产的要求,因此出现了交叉学科、新兴学科等知识生产模式。知识政策应体现知识分类这一现状并使之制度化;大学为实现三大功能,需要进行一种合目的性的学科群建设,以学科群组织人才培养模式。

Self-Concept: A comparison of Native American and Anglo preschoolers

This study compared the scores of Native American and Anglo American preschoolers on the Primary Self-Concept Inventory, a self-report measure of self-concept. Fifty-eight preschoolers between the ages of 4-0 and 5-11 participated. Analysis of the variance revealed no overall significant difference between self-concept scores; however, mean scores on the variable of Personal-Self were significantly higher for Native American preschoolers. Lack of overall difference might have been attributable to similar educational, regional, and socioeconomic factors.
