What If We Look at the Body? An Embodied Perspective of Collaborative Learning

The bodily experiences and implications of understanding the functioning of the human brain–body mechanism has been a center of attention in the field of cognitive neurosciences for over two decades. Research in this field has enlarged the theories of learning and development, and contributed to changes in educational practices involving language processing, mathematics, and spatial thinking; however, these changes have not yet been applied to the analysis of transversal competencies such as collaborative learning. The aim of this paper is to bridge the theoretical and applied advances in the field of embodied cognition, specifically collaborative learning. The definitions, theoretical frameworks, and current methodological approaches in the field of collaborative learning are reviewed, with a particular focus on those studies that have investigated interactive dynamics in collaborative situations. The need to take the field further by exploring the theoretical perspective of embodied cognition as a possibility that can open the field is also presented. The relevance of investigating learning in groups by analyzing bodily engagements and intersubjectivity is demonstrated and methodological considerations are raised.

     

Outcomes and satisfaction of two optional cadaveric dissection courses: A 3‐year prospective study

Teaching time dedicated to anatomy education has been reduced at many medical schools around the world, including Nova Medical School in Lisbon, Portugal. In order to minimize the effects of this reduction, the authors introduced two optional, semester‐long cadaveric dissection courses for the first two years of the medical school curriculum. These courses were named Regional Anatomy I (RAI) and Regional Anatomy II (RAII). In RAI, students focus on dissecting the thorax, abdomen, pelvis, and perineum. In RAII, the focus shifts to the head, neck, back, and upper and lower limbs. This study prospectively analyzes students' academic achievement and perceptions within the context of these two, newly‐introduced, cadaveric dissection courses. Students' satisfaction was assessed anonymously through a questionnaire that included items regarding students' perception of the usefulness of the courses for undergraduate teaching, as well as with regards to future professional activity. For each of the three academic years studied, the final score (1 to 20) in General Anatomy (GA), RAI, and RAII was on average 14.26 ± 1.89; 16.94 ± 1.02; 17.49 ± 1.01, respectively. The mean results were lower in GA than RAI or RAII (P < 0.001). Furthermore, students who undertook these courses ranked them highly with regards to consolidating their knowledge of anatomy, preparing for other undergraduate courses, and training for future clinical practice. These survey data, combined with data on participating students' academic achievement, lend strong support to the adoption of similar courses as complementary and compulsory disciplines in a modern medical curriculum.

Students’ perceptions of the value of electronic feedback—Does disciplinary background really matter?

Feedback on student work is a key mechanism for improving learning in higher education (HE) and can be provided in a variety of forms. Recently, many institutions have moved to the provision of electronic feedback, although evidence for the effectiveness of this is mixed. While many studies evaluating the students’ perception of feedback are now available, there is little evidence of contrasting perceptions of its value according to different disciplines. This work aims to evaluate the relationship between students’ expectations and perception of feedback, especially electronic, and the disciplinary area of study in HE. Students (n = 1017) across different courses from a post-1992 university in the UK were surveyed and categorised into five disciplinary clusters: Science, Technology, Engineering and Mathematics; Business and Accounting; Art and Design; Media and Languages; and Psychology and Social Care. Perceived relevance as well as the most pertinent features and expectations of the quality of electronic feedback for students varies according to disciplinary cluster and thus closely aligns with a specific cluster’s learning and teaching practices. The findings of this study may help institutions to reflect on the role of electronic feedback as part of their ongoing assessment practice and how teaching in the different disciplines may result in different understandings of the value of electronic feedback.     

Valuing indigenous knowledge: to call it “science” will not help

In this commentary on Brayboy and Castagno’s paper, published in this volume, we discuss, on the one hand, many points of agreement between their proposal of culturally responsive schooling for indigenous youth and El-Hani and Mortimer’s proposal of culturally-sensitive science education. On the other hand, we focus on a key disagreement, not only with Brayboy and Castagno, but with a whole body of literature on multicultural, postcolonialist, postmodernist education. The main point of disagreement lies in the fact that we are not sure that to broaden the concept of science so as to talk about “native science” or “indigenous science” is indeed the best strategy to attain a goal that we wholeheartedly share with Brayboy and Castagno, to value other ways of knowing for their own sake, validity, and legitimacy.

Do school entry laws affect educational attainment and labor market outcomes?

Age based school entry laws force parents and educators to consider an important tradeoff: though students who are the youngest in their school cohort typically have poorer academic performance, on average, they have slightly higher educational attainment. In this paper we document that for a large cohort of California and Texas natives the school entry laws increased educational attainment of students who enter school early, but also lowered their academic performance while in school. However, we find no evidence that the age at which children enter school effects job market outcomes, such as wages or the probability of employment. This suggests that the net effect on adult labor market outcomes of the increased educational attainment and poorer academic performance is close to zero.     

The Nature of Science in Science Curricula: Methods and concepts of analysis

The article shows methods and concepts of analysis of the nature of science in science curricula through an exemplary study made in Portugal. The study analyses the extent to which the message transmitted by the Natural Science curriculum for Portuguese middle school considers the nature of science. It is epistemologically and sociologically grounded with particular emphasis on Bernstein's theory of pedagogic discourse and Ziman's conceptualization of science construction. The study used a mixed methodology and followed a dialectical process between the theoretical and the empirical. The results show that the nature of science has a low status in the curriculum with the exception of the external sociological dimension of science. Intra-disciplinary relations between scientific and metascientific knowledge are mostly absent. Recontextualization processes occurred between the two main parts of the curriculum. These results are discussed and their consequences in terms of scientific learning are explored. The mode of analysis used in the study has the potential of highlighting the level of a science curriculum, in terms of specific aspects of the nature of science.     

Moulding urban children towards environmental stewardship: the Table Mountain National Park experience

The environmental integrity of many urban protected areas in developing countries is at risk and the important mission to reach out to people living close to them provides a special opportunity to spread the conservation message. Guided visitation to urban national parks with the necessary and appropriate interpretation can contribute towards environmental education in general and can also be the point of departure in nurturing environmental stewardship. The research reported here focuses on the evaluation of a three-day nature-learning experience by schoolchildren to Table Mountain National Park. Data were collected through pre- and post-visit questionnaires and supplemented by informal discussions with learners and teachers. It was found that the environmental interpretive programme had a minimal impact on the learners’ environmental knowledge, it had a reasonable impact on the pro-environmental attitudes but the findings also indicated that the behavioural impacts were limited. Other important findings were related to behaviours of learners towards environmental issues in general and critical areas in simple pro-environmental behaviour that could be emphasised in future edutainment experiences to contribute more substantially towards moulding stewardship behaviour among young school children.     

Unsettling orthodoxies: education for the environment/for sustainability

In this paper I employ Foucault's notion of governmentality to reflect on a debate that occurred in the pages of this journal some 10 years ago. I argue that their exchanges indicate ways in which various positions are engaged in a struggle for dominance in this field, and how particular strategies are used to legitimate and maintain these positions. My purpose is not to propose a new orthodoxy – or even to critique those we have – but rather to raise questions about how the unquestioned ‘that‐which‐is’ of orthodoxies comes to be, and their effects. I also suggest that as environmental educators and researchers, we need to work harder to unsettle more often the taken‐for‐granted in environmental education so that we remain alert to our own easy acceptance of orthodoxies. Without this, we risk our exhortations to those we seek to educate – to think critically, to question assumptions, and so forth – becoming empty rhetoric if we are not practising these ourselves – examining our own, as well as others', assumptions and practices.     

Using matrix norms to estimate the direction of arrival of planar waves on an ULA

SEAD method estimates the direction-of-arrival angles on an uniform linear array based on the difference between the two largest singular values, what is called differential spectrum. Although it presented an outstanding performance, the ability to indicate the source positions was not elucidated yet. Inspired by the differential spectrum formulation we derived a total differential spectrum and found out that the matrix norm induced by the vector 2-norm of a modified spatial covariance matrix can be used to estimate the direction-of-arrival of multiple plane waves. Indeed we show that matrix norms are estimators and we propose their use instead of the singular value decomposition in SEAD-based methods. We present a general mathematical expression in order to explicit the operating principles of the proposed methods. Consequently, we were able to explain how the relation between the arriving and the search angles produces the larger peaks on the differential spectrum. To evaluate the important role played by matrix norms, a thousand experiments were carried out. They showed that the proposed approach proved to be as accurate as the previous SEAD-based methods, while providing a significant reduction on runtime. It also outperformed well-established methods like MODEX regarding the estimation error.
