Phenomenological Methodologies in the Field of Educational Communications and Technology

The purpose of this paper is to clarify the philosophical and methodological variations of phenomenological research methods and their role in the field of educational communication and technology (ECT). Phenomenology is a qualitative research methodology concerned with investigating phenomena as they manifest through lived-experiences. The unit of analysis resides in the intentional meanings of phenomena. Analysis of those intentionalities, however, has evolved over the past century; phenomenologists have viewed intentionality as something that is: described (transcendental phenomenology), interpreted (hermeneutic phenomenology), or resists centering and embraces contexts, situations, and the partial (post-intentional phenomenology) (Vagle 2014, 2018). To conduct phenomenological research, then, one must be able to articulate the specific philosophical underpinnings associated with each approach and the suitability of each approach. To support researchers and practitioners in the field, this paper explicates philosophical and methodological variations of more prominent phenomenological research approaches as well as related issues and affordances. In doing so, this paper offers scholars in the field various perspectives in which to ground future phenomenological research.     

How Computer-Assisted Learning Influences Medical Students' Performance in Anatomy Courses

Anatomy is an essential subject of the medical curriculum. Despite its relevance, the curricular time and logistical resources devoted to teaching anatomy are in decline, favoring the introduction of new pedagogical approaches based on computer-assisted learning (CAL). This new pedagogical approach provides an insight into students' learning profiles and features, which are correlated with knowledge acquisition. The aim of this study was to understand how training with CAL platforms can influence medical students' anatomy performance. A total of 611 medical students attending Musculoskeletal Anatomy (MA) and Cardiovascular Anatomy (CA) courses were allocated to one of three groups (MA Group, CA Group, and MA + CA Group). An association between the performance in these anatomy courses and the number of CAL training sessions was detected. In the MA Group (r = 0.761, P < 0.001) and the MA + CA Group (r = 0.786, P < 0.001), a large positive correlation was observed between musculoskeletal anatomy performance and the number of CAL training sessions. Similarly, in the CA Group (r = 0.670, P < 0.001) and the MA + CA Group (r = 0.772, P < 0.001), a large positive correlation was observed between cardiovascular anatomy performance and the number of CAL training sessions. Multiple linear regression models were performed, considering either musculoskeletal or cardiovascular anatomy performance as the dependent variable. The results suggest that using CAL platforms to study has a positive dose-dependent effect on anatomy performance. Understanding students' individual features and academic background may contribute to the optimization of the learning process.     

Environmental education research in Brazil: some highlights from theses and dissertations

Abstract

This article discusses an analysis of abstracts of Brazilian theses and dissertations on environmental education from a database organised and maintained by a group of researchers in the EArt Project (www.earte.net). In presenting extracts of key trends in this dataset, our aim is to provide a snapshot of the many possible approaches to, and histories of, Brazilian environmental education research. The data also allow us to raise some questions that explore possible ‘blank spots’, ‘blind spots’ and ‘bald spots’ in Brazilian research on environmental education. Given the temporal development of the research field since the 1980s, we illustrate these ‘spots’ by exploring data related to epistemological and methodological diversity, from the viewpoint of knowledge areas as well as the graduate programmes that have been developing research on environmental education. Finally, we draw a picture of the methodological trends that have been privileged by Brazilian researchers, and pose questions as to what is needed in shaping an agenda for research on environmental education in Brazil into the future.

Effects of Different Models of Water-Based Resistance Training on Muscular Function of Older Women

Purpose: To compare the effects of three water-based resistance trainings on neuromuscular parameters of older women. Method: Thirty-six women were randomized to groups: simple set of 30 seconds (1 × 30 s, 66.41 ± 4.71 years, n = 12), multiple sets of 10 seconds (3 × 10 s, 66.50 ± 4.74 years, n = 11), and simple set of 10 seconds (1 × 10 s, 65.23 ± 3.93 years, n = 13). Maximal isometric strength concomitantly with neuromuscular activity during extension and flexion knee was evaluated. In the same exercises, rate of force development at different time intervals was measured. Finally, functional capacity was assessed. Results: All trainings promoted similar improvements in the rate of force develpment of extension (effect size RFD 50 ms: 1 × 30 s .49, 3 × 10 s .67, 1 × 10 s .65; ES RFD 100 ms: 1 × 30 s .76, 3 × 10 s .80, 1 × 10 s .63; ES RFD 250 ms: 1 × 30 s .31, 3 × 10 s .49, 1 × 10 s .37) and flexion knee (ES RFD 50 ms: 1 × 30 s .59, 3 × 10 s .31, 1 × 10 s .48; ES RFD 100 ms: 1 × 30 s .41, 3 × 10 s .44, 1 × 10 s .42; ES RFD 250 ms: 1 × 30 s .57, 3 × 10 s .36, 1 × 10 s .43; ES RFD maximal: 1 × 30 s .63, 3 × 10 s .23, 1 × 10 s .26), however only the 3 × 10 s group improved the performance in the 8-foot up-and-go test (ES 3 × 10 s: .93, 1 × 30: .39, 1 × 10 s: .23). There was a maintenance of the isometric force and neuromuscular activity, except for the activity of the rectus femoris that showed an increase after training in all groups (ES 3 × 10 s: .04, 1 × 30: .36, 1 × 10 s: .50). Conclusion: Water-based resistance training using simple or multiple sets promotes the same gains in rapid strength, however only multiple sets induced improvement on functional capacity.     

Quantification of mercury in XVIII century books by Energy Dispersive X-Ray Fluorescence (EDXRF)

This work describes the quantitative analysis of mercury present in the ink used to colour some books of XVIII century. The mercury content was determined by Energy Dispersive X-ray Spectrometry. This is a non-destructive technique which allows elemental identification and quantification (Z > 13) by atomic physics processes. The organic pigments cannot be identified by this technique, taking into account that its composition is mainly C, O and H. Levels of 2 wt.% and 4.5 wt.% were measured in 1756 and 1753 books respectively. No significant amount of mercury was observed in other red books, on a total of 11, all from XVIII century: 1720, 1732, 1753, 1756, 1780, 1798, 1800. More than one book for each year were analysed. The studied books belong to a private collection, and were selected taking into account the age and the reddish colour of their external parts. High content on Fe were observed in some of the books. This work highlights the application of a physics technique in a very important aspect for art and cultural heritage conservation and restoration, considering that high levels of toxic elements might be found in ancient documents. It is of great importance that preliminary elemental analyses are performed on ancient documents before handling them, because they might constitute some danger for restorers, conservators and collectors. This work highlights, for the first time, the danger of some ancient books. They might contain a very high concentration of mercury, which is toxic for the organism. This is also a particularly important problem of public health never mentioned in literature before.     

Gender and Education: a view from Latin America

Gender and Education publishes articles that are considered as key references in the field, but at present the journal has limited connection with Gender Studies in Latin America. To understand this, all the titles and abstracts of the issues published between 2011 and 2013 were read. In this period, Gender and Education published 141 original articles, and among them only four were about Latin America. Altering this situation demands specific actions, including those that the Editorial Board is already planning. However, such reading brought to light many other questions that might be analysed in the context of the North/South division of intellectual labour. This essay discusses only one of them: the fact that articles about countries in the global South often identify their location in their titles, while this is rare among papers about metropolitan countries. An apparently simple change is suggested: that the authors question themselves about how far their ideas are understandable to readers from other parts of the world.     

Changing knowledge and the academic profession in Portugal

The paper analyses the Portuguese academics' perceptions about changes in their research activities and modes of knowledge production. Quantitative data gathered from an on‐line national survey have been used to develop this analysis. Results reveal that the majority of academics declared that they were not involved in knowledge and technology transfer and that their research activities were not influenced by external sponsors or clients. However, they did recognise that were strong external pressures to reconfigure the epistemologies, ontologies and the institutional conditions under which knowledge is produced. The data analysis also reveals that academics recognise forms of hybridism between autonomy and endogenous dynamics and heteronomy and exogenous dynamics in the development of their research activities and knowledge production.
