RETHINKING THE HISTORY OF INCLUSION OF IKS IN SCHOOL CURRICULA: ENDEAVORING TO LEGITIMATE THE SUBJECT

Much has been said and written about indigenous knowledge systems (IKS) or, as it is also termed, traditional ecological knowledge. My paper does not intend to discuss how it should be termed, although this is also an important issue as the way we name it frames the possibilities we open for this kind of knowledge. The paper rather looks historically at indigenous knowledge inclusion in school curricula, taking as an example the practice in Mozambique. So far, many strategies in so-called culturally inclusive science curricula tend to take students along the pathway of cultural assimilation by integrating IKS into World Modern Science topics. IKS is therefore taken as an instrument for serving the goals of World Modern Science. I argue that we need to find legitimated theories to integrate IKS in order to counteract the practice of teaching IKS in science classrooms detached from its own sociocultural context.     

An innovative concept map approach for improving students' learning performance with an instant feedback mechanism

Concept maps have been widely employed for helping students organise their knowledge as well as evaluating their knowledge structures in a wide range of subject matters. Although researchers have recognised concept maps as being an important educational tool, past experiences have also revealed the difficulty of evaluating the correctness of a concept map. It usually takes days or weeks for teachers to manually evaluate the concept maps developed by students; consequently, the students cannot receive timely feedback from the teachers, which not only affects their learning schedules, but also significantly influences the students' learning achievements. In this paper, a computer‐based concept map‐oriented learning strategy with real‐time assessment and feedback is proposed in order to cope with the problems mentioned above. Our approach provides immediate evaluation of concept maps and gives also real‐time feedback to the students. An experiment has been conducted to evaluate the effectiveness of this new strategy in comparison with the conventional computer‐based concept map approach. It is found that our innovative approach can be significantly beneficial to promote learning achievements as well as the learning attitudes of students.     

The official football match-fixing prevention discourse as a cognitive limitation (the cases of Iberian countries)

This paper shows the cognitive and educational limitations of the official institutional discourse to combat match-fixing in football. Recently, after reaching the political and sports’ institutional agendas, several reports have been published and official prevention campaigns have been launched to fight against the phenomenon. These documents can be understood as an official preventive narrative on the subject. The discursive analysis of the ‘nodal points’ in which this narrative is based displays a lack of holistic awareness of the problem. Many discursive variables that should be part of the diagnoses are avoided. Likewise, the narrative is presented with a universal character, yet the Iberian cases present evidences that contradict it. Based on interviews to key informants and media clipping, this paper shows that these preventive and educational messages produced by international institutions and sport organizations are not useful in Portugal or Spain because they don’t show the reality about this phenomenon.     

Motives,barriers, and ways of communicating in mother-daughter sexuality communication: a qualitative study of college women in Tanzania

In Tanzania, young women aged 15–24 are at high risk for HIV and nearly half (45%) of women experience pregnancy or childbirth before age 19. The HIV epidemic has motivated many parents to overcome cultural taboos and talk with their children about sexuality, but few studies in Tanzania have examined how young adults perceive these discussions. In-depth interviews with 31 Tanzanian college women (ages 18–25) reveal how they make sense of sexuality messages from mothers that are sometimes vague, admonishing and fear-based. Participants identified how mothers focused on the health, educational and social consequences of premarital sex and emphasised the avoidance of men as a strategy to maintain virginity. Mothers avoided providing specific information about safer-sex practices, or strategies to negotiate romantic relationships, sexual pressures or sexual desires. Findings offer insight into how relational and cultural contexts influence mothers’ sexual socialisation and can inform education and intervention approaches that consider the changing cultural landscape. Future qualitative research with mothers is recommended to develop programmes that are more responsive to mothers’ and daughters’ needs.     

Measuring the “transfer of meaning” through members of equivalence classes merged via a class-specific reinforcement procedure

Seven participants received conditional discrimination training that established the 12 conditional relations A1B1, A2B2, A3B3, A1C1, A2C2, A3C3, D1E1, D2E2, D3E3, D1F1, D2F2, and D3F3. The A stimuli were pictures of faces portraying emotional expressions; the others were arbitrary forms. Correct responses resulted in presentations of class-specific reinforcers, Sr1, Sr2, and Sr3. After training, tests confirmed the formation of ABC and DEF equivalence classes. Further tests then documented the merger of the classes and the emergence of SrB, SrC, SrE, and SrF relations, showing that the class-specific reinforcers were equivalence class members. Finally, participants did Semantic Differential ratings that tested whether the emotional valence of the A stimuli transferred to the arbitrary forms, B and E. The results show that participants’ evaluations of the B and E stimuli were similar to evaluations of the A stimuli made by participants of a control group. This finding is considered as a demonstration that class-specific outcomes can mediate class merger phenomena and the transfer of functions through members of merged classes.     

The geometric curvature of the spine during the sirshasana,the yoga’s headstand

This study analysed the behaviour of the geometric curvature of the spine during sirshasana. The position of dorsal retroreflective markers was computed via stereophotogrammetric analysis in six males and five females (29.4 ± 8.8 years, 63.0 ± 11.4 kg, 1.66 ± 0.08 m [average ± standard deviation]). The spinal points were projected onto the sagittal and frontal planes of the trunk, a polynomial was fitted to the data and the two-dimensional geometric curvature was quantified. The inferior lumbar lordosis decreased compared to the orthostatic position and gait, which may favour the posterior protrusion of the lumbar spinal nucleus pulposus in people with posterior herniation. The lateral deviation at the middle of the thoracic spine increases during sirshasana, which may reflect increased difficulties for postural control and spinal loads. It could be useful for promoting positive spinal structural and functional chronic adaptations for healthy participants, if the yoga programme is carefully planned and the spinal alignment is carefully monitored during a headstand. However, it may aggravate some spinal diseases, especially scoliosis.     

Environmental education research in Brazil

Abstract

This Editorial to the current collection provides a brief historical, cultural, regional and contemporary picture of environmental education research in Brazil. Its main purpose is to offer readers a short background and orientation to the collection, and in so doing, illustrate how its contributions relate to some wider tendencies, trends and issues in environmental education, as well as to different locales of research and knowledge generation in the country. Of particular note for environmental education in Brazil are: the effects of social and political backdrops and issues, the unique environments on which environmental education is grounded, and how environmental education research, in turn, may echo or influence particular educational and public policies.     

A study of writing mechanisms in Spanish primary education children / Estudio de los mecanismos de escritura en niños españoles de Educación Primaria

Several studies performed on deep orthography systems reveal variables that influence writing latencies that occur over the course of learning. In transparent orthographies such as Spanish there are very few studies on writing that measure latencies and duration. The aim of this present study was to take a more in-depth look at knowledge of the writing mechanisms used by Spanish children in primary education, by studying the errors, latencies and duration of the writing of words. To do this, sixty children performed a copying task and a dictation task with regular words of different frequency and length. The obtained results show changes in the writing mechanisms used by the children as they became more expert, as indicated by the greater effect of word length in the first years of primary. This word length effect is a more determining factor with regard to the number of letters in words than for the number of syllables. These results hold important implications for the teaching of writing in Spanish.     

Male professional tennis players maintain constant serve speed and accuracy over long matches on grass courts

The potential effect of fatigue on stroke production in tennis players is still controversial. The aim of this study was to analyse the tennis serve speed and accuracy in prolonged male professional matches played on grass courts. We analysed tennis serve statistics from five-set Wimbledon matches (n?=?15; 30 players). Results showed that match duration averaged 208.3?±?28.3?min. The overall serve speed was 177.0?±?10.2?km/h in the first set and 176.1?±?11.7?km/h in the fifth set (p?=?.34). The difference of all accuracy values of first set serves was not significantly different from those of the fifth set: percentage of valid first serves, 63.1?±?11.1% vs. 62.3?±?11.8%, respectively (p?=?.78); percentage of “aces”, 11.2?±?9.1% vs. 10.0?±?8.9%, respectively (p?=?.39); percentage of “winners”, 2.6?±?7.6% vs. 1.2?±?2.2%, respectively (p?=?.36); percentage of “double faults”, 2.8?±?3.0% vs. 2.8?±?3.4% (p?=?.97). In conclusion, tennis players were able to maintain constant serve speed and accuracy over five-set matches played on grass courts. Professional tennis players are capable of overcoming fatigue and/or make movement adjustments to effectively perform complex technical strokes like the serve throughout matches played on grass courts lasting more than 3?h in average.
