Spatial abilities in an elective course of applied anatomy after a problem‐based learning curriculum

A concern on the level of anatomy knowledge reached after a problem‐based learning curriculum has been documented in the literature. Spatial anatomy, arguably the highest level in anatomy knowledge, has been related to spatial abilities. Our first objective was to test the hypothesis that residents are interested in a course of applied anatomy after a problem‐based learning curriculum. Our second objective was to test the hypothesis that the interest of residents is driven by innate higher spatial abilities. Fifty‐nine residents were invited to take an elective applied anatomy course in a prospective study. Spatial abilities were measured with a redrawn Vandenberg and Kuse Mental Rotations Test in two (MRT A) and three (MRT C) dimensions. A need for a greater knowledge in anatomy was expressed by 25 residents after a problem‐based learning curriculum. MRT A and C scores obtained by those choosing (n = 25) and not choosing (n = 34) applied anatomy was not different (P = 0.46 and P = 0.38, respectively). Percentage of residents in each residency program choosing applied anatomy was different [23 vs. 31 vs. 100 vs. 100% in Family Medicine, Internal Medicine, Surgery, and Anesthesia, respectively; P < 0.0001]. The interest of residents in applied anatomy was not driven by innate higher spatial abilities. Our applied anatomy course was chosen by many residents because of training needs rather than innate spatial abilities. Future research will need to assess the relationship of individual differences in spatial abilities to learning spatial anatomy.

Toward a framework for the development of mathematical knowledge for teaching

Shulman (1986, 1987) coined the term pedagogical content knowledge (PCK) to address what at that time had become increasingly evident—that content knowledge itself was not sufficient for teachers to be successful. Throughout the past two decades, researchers within the field of mathematics teacher education have been expanding the notion of PCK and developing more fine-grained conceptualizations of this knowledge for teaching mathematics. One such conceptualization that shows promise is mathematical knowledge for teaching—mathematical knowledge that is specifically useful in teaching mathematics. While mathematical knowledge for teaching has started to gain attention as an important concept in the mathematics teacher education research community, there is limited understanding of what it is, how one might recognize it, and how it might develop in the minds of teachers. In this article, we propose a framework for studying the development of mathematical knowledge for teaching that is grounded in research in both mathematics education and the learning sciences.

On the Epistemology of Narrative Research in Education

The purpose of this article is to explore the epistemological foundations of narrative research in education. In particular, I seek to explain how one can obtain knowledge, given its origin in teachers' subjective experiences. The problem with rhetorical and aesthetic criteria that narrative researchers use to warrant their knowledge claims is not that they don't meet a correspondence criterion of truth as post‐positivists contend, but rather that they fail to connect teachers' ethical views with their practice. Since narrative research is aimed at understanding teachers' actions and not at seeking some kind of mechanism in teachers' behaviour, the link between past experiences and present teaching practice is not causal but teleological. I suggest that although the knowledge claims of narrative researchers may not be justified (because they don't meet the criteria of truth as correspondence theory), we might nonetheless be intellectually entitled to accept them. Entitlement is an epistemic right or warrant that constitutes knowledge as justification, but uses different reasons—teleological not causal explanations. I offer three criteria to establish entitlement to accept narrative researchers' findings: (1) the meeting of rhetorical standards such as plausibility, adequacy, and persuasion; (2) the inclusion of teachers' stories about their pedagogical practice; (3) the meeting of ethical criteria that connects a teacher's actions to an articulate and defensible end‐in‐view or vision of the good.     

Lifelong learning and the knowledge economy: those that know and those that do not—the discourse of the European Union

This article is based on a textual analysis of European Commission documents that, from 1993 to 2006, construct the discourses of lifelong learning and the knowledge economy. Exploring an apparent conceptual laxity, it finds absolute consistency in the construction of two categories of learner: the high knowledge‐skilled learner (graduate/postgraduate) for the knowledge economy, and the low knowledge‐skilled learner located in (or beyond) the knowledge society. The low knowledge‐skilled learners are not only those at risk, they are increasingly constructed as the risk. The analysis suggests that the binary classification is initially classed and raced—and only then is it gendered. In contrast, labour market studies of the knowledge economy, providing either gendered or national data, obscure the vital cross‐cutting matrix of social class, ‘race’ and age. The article advocates further studies of lifelong learning practices and labour market data based on finely‐crossed analyses of social class, poverty, age and race.     

Testing the instructional fit hypothesis: the case of self-explanation prompts

Cognitive science principles should have implications for the design of effective learning environments. The self-explanation principle was chosen for the current work because it has developed significantly over the last 20 years. Early formulations hypothesized that self-explanation facilitated inference generation to supply missing information about a concept or target skill, whereas later work hypothesized that self-explanation facilitated mental-model revision (Chi, Handbook of research on conceptual change, 2000). To better understand the complex relationship between prior knowledge, cognitive processing, and changes to a learner’s representation, two classes of self-explanation prompts (gap-filling and mental-model revision) were tested in the domain of physics problem solving. Prompts designed to focus the learner on gap-filling led to greater learning and a reduction in the amount of tutoring assistance required to solve physics problems. The results are interpreted as support for the instructional fit hypothesis—the idea that the efficacy of instruction is contingent on the match between the cognitive processing that the instruction elicits, how those processes modify the underlying knowledge representations for the task, and the utility of those representations for the task or problem.     

An Objectivist Critique of Relativism in Mathematics Education

Many constructivists tag as `absolutist' references to mathematics as an abstract body of knowledge, and stake-out the moral high-ground with the argument that mathematics is not only utilised oppressively but that mathematics is, in-itself, oppressive. With much reference to Ernest's (1991) Philosophy of Mathematics Education this tag has been justified on the grounds that if mathematics is a social-cultural creation that is mutable and fallible then it must be social acceptance that confers the objectivity of mathematics. This paper argues that mathematics, albeit a social-cultural creation that is mutable and fallible, is a body of knowledge the objectivity of which is independent of origin or social acceptance. Recently, Ernest (1998) has attempted to express social constructivism as a philosophy of mathematics and has included the category of logical necessity in his elaboration of the objectivity of mathematics. We argue that this inclusion of logical necessity not only represents a U-turn, but that the way in which Ernest has included this category is an attempt to maintain his earlier position that it is social acceptance that confers the objectivity of mathematics.     

Changing knowledge regimes: Universities in a new research environment

This paper takes an apparent knowledgeparadox as its point of departure. `Knowledge'has acquired a more all encompassing meaningtoday, yet this has not strengthened thesupport for and confidence in higher educationinstitutions. On the contrary, it is oftenclaimed that they have outlived theirusefulness. In trying to understand thedevelopment behind this paradox, we deal withthree issues. We discuss first thewidening concept of knowledge and the claimthat there is emerging a new mode of knowledgeproduction. Secondly the widening concept ofknowledge is put into a social and politicalcontext, where massification and its socialimplications are discussed. Thirdly we developa theoretical framework based on the concept ofknowledge regimes. In this part wediscuss how the concept of knowledge regimesand the related concepts of knowledgeinterests and knowledge alliances may behelpful in understanding the complexities andambiguity of higher education development.Finally we discuss some implications regardingknowledge's role in social development. Wequestion the assumption that there is anecessary relationship between a wideningconcept of knowledge and a given form ofknowledge development.     

Is Knowledge Insertion Desirable?

In this article, John Tillson discusses the conditions under which what he calls “knowledge insertion” would be desirable for the one who has knowledge inserted. He argues that making use of knowledge insertion would not be cost free; in particular, it would come at the price of relationship goods realized through teacher–learner relationships, and of the achievement of learning, at least for the knowledge inserted. Despite these costs, though, Tillson concludes that knowledge insertion would most often be desirable since the losses could usually be more than compensated by the knowledge gained or would matter little so long as one realizes the relevant relationship and achievements goods to a satisfactory level at some point in one's life.     

Farmers’ Visions on Soils: A Case Study among Agroecological and Conventional Smallholders in Minas Gerais,Brazil

Abstract

Purpose: Why do farmers not take better care of their soils? This article aims to give insight into how farmers look at soil quality management.

Design/methodology/approach: It analyses diverse land management practices and visions on soils and soil quality of ten agroecological and 14 conventional smallholder farmers in Araponga, Minas Gerais, Brazil. As agroecological farming (that is, managing soils with minimum use of external inputs) requires more complex knowledge, it is assumed that agroecological farmers would be more knowledgeable on soils compared to conventional farmers. This case study tests the hypothesis that differences in land management practices between agroecological and conventional farmers can be explained by differences in their knowledge on soils.

Findings: The hypothesis turned out to be faulty: agroecological and conventional farmers do not differ in what they know about soils, but how they use their knowledge in their farming strategy. Both groups of farmers have different but rational farming strategies.

Practical implications: Designing policies and measures to make farming more environmentally friendly and more sustainable as two-way knowledge exchange between farmers and science (and not as one-way knowledge transfer from science to farmers), to benefit from vital and context-based farmers’ knowledge and to ensure successful implementation of more sustainable land management practices.

Originality/value: By analysing farmers’ visions on soil quality management and farming strategies, this study shows that farmers’ knowledge is valuable for farmers, for scientific knowledge on soil quality management and for policies which are to be effective and adapted to the local environment.     

University knowledge in an age of supercomplexity

For various reasons, it is becoming felt that the knowledge function of the university is being undermined. Some, indeed, have come to suggest that we are witnessing 'the end of knowledge' in higher education. The 'end of knowledge' thesis takes three forms. Substantively, it is felt that the knowledge sustained by the university has no particular status: it simply takes its place and its chances amid the proliferating knowledges that society has now to offer. Ideologically, it is felt that the knowledge for which the university stands lacks legitimacy: it can simply be understood as a set of language games of a rather privileged set of occupational groups ('academics') that reflects their interests and marginal standing to the rest of society. Procedurally, it is implied that the university can now only secure its future by becoming entrepreneurial and by marketing its knowledge wares in forms of academic capitalism; in the process, its knowledge becomes performative in character and loses its power to enlighten. Much of this analysis is correct – even as the theses cut across each other – butthe conclusion is wrong. The modern world is supercomplex in character: it can be understood as a milieu for the proliferation of frameworks by which we might understand the world, frameworks that are often competing with each other. In such an age of supercomplexity, the university has new knowledge functions: to add to supercomplexity by offering completely new frames of understanding (so compounding supercomplexity); to help us comprehend and make sense of the resulting knowledge mayhem; and to enable us to live purposefully amid supercomplexity. Knowledge, as a pure, objective reading of the world does have to be adandoned. But the university is not, thereby, delegitimised. In an age of supercomplexity, a new epistemology for the university awaits, one that is open, bold, engaging, accessible, and conscious of its own insecurity. It is an epistemology for living amid uncertainty.     

The Performance of Chinese Primary School Students on Realistic Arithmetic Word Problems

Compared with standard arithmetic word problems demanding only the direct use of number operations and computations, realistic problems are harder to solve because children need to incorporate “real‐world” knowledge into their solutions. Using the realistic word problem testing materials developed by Verschaffel, De Corte, and Lasure [Learning and Instruction, 4(4), 273–294, 1994], two studies were designed to investigate (a) Chinese elementary school children’s ability to solve realistic word problems and (b) the different effects of two instructional interventions (warning vs. process‐oriented) on their performance. The results indicated that, contrasting to the standard problem solving, the participating children demonstrated a strong tendency to exclude real‐word knowledge and realistic considerations from their solution processes when solving the realistic problems. Process‐oriented instruction, calling for a deep‐level processing, was more likely than warning instruction to promote the activation of realistic considerations, but it was not effective at helping children arrive at realistic or correct answers. Finally, the results and their implications for mathematical teaching are discussed.     

The online learning environment—A new model using social constructivism and the concept of ‘Ba’ as a theoretical framework

Organisations that provide education are businesses and, as such, are not immune from the impact that the Internet has had in recent years, both on the way organisations conduct their business and as a business supporting technology. Indeed, the use of the Internet as a facilitating mechanism for educational course delivery has been growing steadily over the last 5–8 years and, although there are some significant issues that have arisen in that time in relation to the quality of learning that can be achieved, there is no doubt that it will continue to be developed as an educational tool. The real issue for educators is, therefore, not whether the Internet will be used in course delivery, or if it is a useful tool, but rather how can a teacher make best use of it to enhance learning? This article documents a study that has analysed five years of student reflections on the scaffolding mechanisms used to promote and encourage learning in five Internet-based courses at the University of Queensland run between 2001 and 2005. The courses involved include three Internet-delivered Masters coursework courses and two Internet-delivered undergraduate courses in three different discipline areas. The outcomes of the study are: (1) a Report Card documenting student evaluations of the scaffolding mechanisms used; (2) a What, Why, How, Where framework of scaffolding mechanisms that are best suited to enabling deep learning through the online environment, and (3) a proposed new model of knowledge acquisition in online learning environments entitled ESCIE, which is based on Nonaka’s SECI and Ba models of knowledge creation.     

A Spiral Task as a Model for In-service Teacher Education

The spiral approach has long been used by curriculum designers to deepen students’ knowledge of scientific and mathematical concepts and to bring students to higher levels of abstraction. The benefits of a spiral approach, however, can also be extended to teacher education. This paper describes a spiral activity employed by the Kidumatica program not only to raise the level of teachers’ content knowledge, but also to promote discussion and collaboration among teachers teaching at different grade levels. The activity was designed to take a single problem situation and develop it in ways appropriate to the different grade levels. At each stage, the teachers are encouraged to discuss teaching approaches required by the students at each grade level and the relationships between the different stages of the development.     

Can Educationally Significant Learning be Assessed?

Abstract

This article argues that assessment is a central feature of teaching, particularly as a means to determine whether what has been taught has been learnt. However, I take issue with the current trend in education which places a significant amount of emphasis upon large-scale public testing, which in turn has exacerbated the ‘teaching-to-the-test’ syndrome, not to mention distorting teaching decisions that are detrimental to the overall development of student knowledge and understanding. Part of the problem with assessment in education seems to revolve around the nature of knowledge and how best to assess human knowledge and understanding. Although much philosophical uncertainty and disagreement exists surrounding the nature of knowledge, I argue that coming to know something is a sine qua non of any education. In saying this, I highlight the limits of assessment by demonstrating how certain activities are resistant to large-scale public testing because they are not easily reducible to facts which can be tested for, or at least in the same way as propositional forms of knowledge. Consequently, my argument is a philosophical one to the effect that assessment, particularly large-scale public testing is incapable of assessing all forms of learning, or even the quality of student understanding because the instruments available are both too blunt and tend to capture a certain kind of knowledge that privileges theory over practice, and mental skills over physical skills.     

Development of orthographic knowledge in German‐speaking children: a 2‐year longitudinal study

There is growing evidence that children develop orthographic knowledge from the very beginning of literacy acquisition. This study investigated the development of German‐speaking children's orthographic knowledge with a nonword choice task. One nonword in each pair contained a frequent consonant doublet (zommul) and the other nonword contained an infrequent doublet (zobbul). Children (N = 54) performed at chance level in kindergarten but chose nonwords with frequent doublets significantly more often than expected by chance in first and second grade. Correlations between children's orthographic knowledge and their reading and spelling skills were not found. The results indicate that knowledge of frequent double consonants is evident in German‐speaking children from first grade onwards, but it is not related to their reading and spelling performance. This finding is consistent with the view that children in transparent orthographies rely less on frequent letter patterns during reading and spelling compared to children in deep orthographies.     

Content,Joseph Schwab and German Didaktik

This article attempts to extend and deepen the conversation concerning the knowledge-based approach to curriculum espoused by Michael Young in his 2013 JCS paper through revisiting the structure of the disciplines thinking of Joseph Schwab and German Didaktik. It argues that curriculum making requires a theory of knowledge that not only differentiates different types of knowledge but also elucidates the concepts, theories, methods and habits of mind within a particular knowledge type that contribute to the cultivation of students’ intellectual and moral powers or capacities. Furthermore, it needs a theory of content that addresses how knowledge is selected and transformed into curriculum content, what educational potential content has, and how such potential can be disclosed or unlocked for the cultivation.     

The benefit of being naïve and knowing it: the unfavourable impact of perceived context familiarity on learning in complex problem solving tasks

Previous research has found that embedding a problem into a familiar context does not necessarily confer an advantage over a novel context in the acquisition of new knowledge about a complex, dynamic system. In fact, it has been shown that a semantically familiar context can be detrimental to knowledge acquisition. This has been described as the “semantic effect” (Beckmann, Learning and complex problem solving, Bonn, Holos, 1994). The aim of this study was to test two competing explanations that might account for the semantic effect: goal adoption versus assumptions. Participants were asked to learn about the causal structure of a linear system presented on a computer containing three outputs by changing three inputs through goal free exploration. Across four conditions the level of familiarity was experimentally varied through the use of different variable labels. There was no evidence that goal adoption can account for poor knowledge acquisition under familiar conditions. Rather, it appears that a semantically familiar problem context invites a high number of a priori assumptions regarding the interdependency of system variables. These assumptions tend not to be systematically tested during the knowledge acquisition phase. The lack of systematicity in testing a priori assumptions is the main barrier to the acquisition of new knowledge. The semantic effect is in fact an effect of untested presumptions. Implications for research in problem solving, knowledge acquisition and the design of computer-based learning environments are discussed.     

Theory and Practice ‐‐Two Fundamental Categories in the Philosophy of Teacher Education

Taking the Swedish teacher education as its point of departure, two related problems are discussed in the article. 1) Practice is often understood as completely immersed in itself. Consequently there arises the problem if and how it can get out of this enclosedness and get some perspective on itself. Three ways are proposed of introducing distance into practice and, thereby, of establishing knowledge about practice: self‐reflection, dialogue, and scientific research. 2) Sometimes theory and practice are regarded as absolutely different and incompatible. According to this kind of dualism it is not possible to integrate any kind of theoretical knowledge into teachers professional actions. By showing how distance can be eliminated from theory and transformed into practical skill, it is argued that this dualism is not maintainable.     

What Might Dewey Think of Knowledge Insertion?

In two articles, “Might Knowledge Be Insertable?” and “Is Knowledge Insertion Desirable?,” John Tillson argues that knowledge insertion is conceivable and desirable for the person who has it inserted. By knowledge insertion, he means the immediate or almost immediate acquisition of knowledge by means other than traditional processes of learning. He takes the case presented in the science fiction film The Matrix as paradigmatic and characterizes it as a special case of direct intervention, which begin with change in brain structure and function and result in in changes in thought patterns and behavior, by contrast to indirect interventions, which begin with changes in thought patterns and behavior and result in rewiring brain structure and functioning. Here, Gonzalo Obelleiro follows Tillson's argument and offers one special case in which knowledge insertion is not desirable and that is not fully elucidated by Tillson's conditions for desirability. John Dewey's notion of growth as summum bonum depends in important ways on gradual, progressive, traditional processes of learning. Deweyan growth constitutes a case of intrinsically valuable learning that can be tragically jeopardized by calculation errors in knowledge insertion. This is a significant risk that Tillson does not consider in his articles.
