Integrating environmental education in primary school education in Tanzania : teachers’ perceptions and teaching practices

The study focuses on primary school teachers’ perceptions of environmental education, its integration into primary school education and teachers’ teaching practices in Tanzania. The thesis is based on empirical research. The theoretical underpinnings of the study are based on Palmer’s (1998) model of environmental education. According to the model, meaningful environmental education should include education about, in or through and for the environment. The study is supported by national and international literature from research done on environmental education and education for sustainable development and policy statements. The study is qualitative in nature, adopting phenomenography and phenomenology as points of departure. The empirical data was collected from four primary schools in Morogoro region in Tanzania. The study sample consisted of 31 primary school teachers. Data was collected through interviews and lesson observations. According to the results of the study, primary school teachers expressed variations in their perceptions of environmental education and education for sustainable development. Most of the teachers focused on the aspect of knowledge acquisition. According to Tanzanian education and training policy, environmental education has to be integrated into all subjects. Although there is environmental education in the primary school curriculum, it is not integrated on an equal footing in all subjects. Some subjects like science, social studies and geography have more environmental content than other subjects. Teachers claim that the approach used to integrate environmental education into the school curriculum was not favoured because many claimed that what is to be taught as environmental education in the various subjects is not shown clearly. As a result, many teachers suggested that to ensure that it is taught properly it should be included in the curriculum as an independent subject or as specific topics. The study revealed that teachers’ teaching practices in integrating environmental education varied from one subject to another. Although most of the teachers said that they used participatory methods, lesson observations showed that they limited themselves to question and answer and group discussion. However, the teachers faced a number of barriers in the teaching of environmental education, some of which include lack of teaching and learning resources, time and large class size. The role of teachers in the implementation of environmental education in developing an environmentally literate citizenry is of great significance. The responsibility of the government in developing a curriculum with clear goals and content, developing teachers’ capacity in the teaching of environmental education and provision of teaching and learning materials needs to be taken seriously by the government in educational plans and programs.

Learning through role-playing games: an approach for active learning and teaching

This study evaluates the use of role-playing games (RPGs) as a methodological approach for teaching cellular biology, assessing student satisfaction, learning outcomes, and retention of acquired knowledge. First-year undergraduate medical students at two Brazilian public universities attended either an RPG-based class (RPG group) or a lecture (lecture-based group) on topics related to cellular biology. Pre- and post-RPG-based class questionnaires were compared to scores in regular exams and in an unannounced test one year later to assess students' attitudes and learning. From the 230 students that attended the RPG classes, 78.4% responded that the RPG-based classes were an effective tool for learning; 55.4% thought that such classes were better than lectures but did not replace them; and 81% responded that they would use this method. The lecture-based group achieved a higher grade in 1 of 14 regular exam questions. In the medium-term evaluation (one year later), the RPG group scored higher in 2 of 12 questions. RPG classes are thus quantitatively as effective as formal lectures, are well accepted by students, and may serve as educational tools, giving students the chance to learn actively and potentially retain the acquired knowledge more efficiently.

The influence of familial smoking behaviours on adolescent smoking behaviours

The ability to identify adolescents who are at risk for becoming smokers may prove useful in developing effective smoking prevention programs. The purpose of this stUdy was to assess the importance of familial smoking behaviours on adolescent smoking patterns. The results were based on responses to The Grade 7 Lincoln County Smoking Survey designed by Chudzik and Partington (1994), and are a part of the "Peer Assisted Learning Program· (PAL) presented by the Niagara Regional Health Services Department, with the cooperation of a local Board of Education (Region of Niagara). The results indicate that 12% of the total group of 450 Grade 7 student respondents were current smokers at the time the data were collected (13% males and 11% females), while more than 37% of individuals indicated that they had tried smoking previously. Of the individuals who were classified as smokers, 11% reported that they smoked because their parents smoked, but only 6% reported that they smoked because their siblings smoked. More concerning, however, is the finding that 4% of smokers reported that they felt pressured to smoke by their relatives. In a society that is becoming increasingly concerned about health, it is also alarming to observe that only 50% of the respondents within this sample reported that there were no smokers (parents/siblings) in their homes. The results also indicate that 33% percent of respondents had grandparents who continued to smoke, and 53% of respondents indentified other relatives who continued to smoke.

Canadian curling coaches' use of psychological skills training

Hom's (2008) model of coaching effectiveness proposes a series of direct relationships between the beliefs and values of coaches, their behaviours, and the perceptions of their athletes. One specific area of coaching behaviour that is in need of more research is their use of psychological skills training (PSn. The purpose of this study was to examine the relationship between the beliefs and behaviours of curling coaches with respect to PST, and the perceptions of their athletes. In collaboration with the Canadian Curling Association, data was collected from a national sample of 115 curling teams with varying levels of competition and experience. One hundred and fifteen coaches completed PST attitude (SPA-RC-revised) and behaviour (MSQ-revised) measures, while 403 athletes completed two perception measures (CCS and S-CI). Interclass correlation coefficients (ICC) were calculated to ensure intra-team consistency. All ICCs were positive, ranging from r =.39 to .56, and significant at the p < .01 level. A series of multiple regressions were performed. Three of the four regression models were significant, with coaches' PST behaviours accounting for 16% of the variance in athletes' evaluation of their coaches' competencies (GeC). The models for athletes' PhysicalSport Confidence (P-SC) and Cognitive-Sport Confidence (C-SC) accounted for 15% and 36% of the variation, with GCC and coaches' PST behaviours both being significant predictors of the models. After statistically controlling the influence of GCC, coaches' PST behaviours accounted for 3% and 26% of the variation in athletes P-SC and C-SC. These results provide partial support for Hom's (2008) model of coaching effectiveness, and offer new insight into the benefits of coaches' use of sport psychology-related training behaviours.

Beta2-agonists use during pregnancy and the risk of congenital malformations

Selon les lignes directrices de traitement de l'asthme pendant la grossesse, les beta2-agonistes inhalés à courte durée d’action (SABA) sont les médicaments de choix pour tous les types d’asthme [intermittent, persistant, léger, modéré et sévère] comme médicaments de secours rapide et dans la gestion des exacerbations aiguës. D’autre part, les beta2-agonistes inhalés à longue durée d’action (LABA) sont utilisés pour les patients atteints d'asthme persistant, modéré à sévère, qui ne sont pas entièrement contrôlés par des corticostéroïdes inhalés seuls. Malgré que plusieurs études aient examinées l’association entre les LABA, les SABA et les malformations congénitales chez les nouveau-nés, les risques réels restent controversés en raison de résultats contradictoires et des difficultés inhérentes à la réalisation d'études épidémiologiques chez les femmes enceintes. L'objectif de cette étude était d'évaluer l'association entre l'exposition maternelle aux SABA et LABA pendant le premier trimestre de grossesse et le risque de malformations congénitales chez les nouveau-nés de femmes asthmatiques. Une cohorte de grossesses de femmes asthmatiques ayant accouchées entre le 1er janvier 1990 et le 31 décembre 2002 a été formée en croisant trois banques de données administratives de la province de Québec (Canada). Les issues principales de cette étude étaient les malformations congénitales majeures de touts types. Comme issues secondaires, nous avons considéré des malformations congénitales spécifiques. L'exposition principale était la prise de SABA et/ou de LABA au cours du premier trimestre de grossesse. L'exposition secondaire étudiée était le nombre moyen de doses de SABA par semaine au cours du premier trimestre. L'association entre les malformations congénitales et la prise de SABA et de LABA a été évaluée en utilisant des modèles d’équations généralisées (GEE) en ajustant pour plusieurs variables confondantes reliées à la grossesse, l’asthme de la mère et la santé de la mère et du foetus. Dans la cohorte formée de 13 117 grossesses de femmes asthmatiques, nous avons identifié 1 242 enfants avec une malformation congénitale (9,5%), dont 762 avaient une malformation majeure (5,8%). Cinquante-cinq pour cent des femmes ont utilisé des SABA et 1,3% ont utilisé des LABA pendant le premier trimestre. Les rapports de cotes ajustées (IC à 95%) pour une malformation congénitale associée à l'utilisation des SABA et des LABA étaient de 1,0 (0,9-1,2) et 1,3 (0,9-2,1), respectivement. Les résultats correspondants étaient de 0,9 (0,8-1,1) et 1,3 (0,8-2,4) pour les malformations majeures. Concernant le nombre moyen de doses de SABA par semaine, les rapports de cotes ajustées (IC à 95%) pour une malformation congénitale était de 1.1 (1.0-1.3), 1.1 (0.9-1.3), et 0.9 (0.7-1.1) pour les doses >0-3, >3-10, and >10 respectivement. Les résultats correspondants étaient de 1.0 (0.8-1.2), 0.8 (0.7-1.1), et 0.7 (0.5-1.0) pour les malformations majeures. D'autre part, des rapports de cotes (IC à 95%) statistiquement significatifs ont été observés pour les malformations cardiaques (2.4 (1.1-5.1)), les malformations d'organes génitaux (6.8 (2.6-18.1)), et d'autres malformations congénitales (3.4 (1.4 à 8.5)), en association avec les LABA pris pendant le premier trimestre. Notre étude procure des données rassurantes pour l’utilisation des SABA pendant la grossesse, ce qui est en accord avec les lignes directrices de traitement de l’asthme. Toutefois, d'autres études sont nécessaires avant de pouvoir se prononcer sur l’innocuité des LABA pendant la grossesse.

Sunlight exposure and prostate cancer risk : a case-control study in Montreal, Canada

Objectifs: Évaluer l’association entre l’exposition récréative, professionnelle et globale au soleil et le risque de cancer de la prostate (CaP). Méthodes: Dans le contexte d’une étude cas-témoins sur le CaP menée à Montréal, Canada, des entrevues ont été complétées auprès de 1371 cas incidents de CaP diagnostiqués en 2005-2009, et 1479 témoins de la population générale. Des questionnaires détaillés ont permis d’obtenir de l’information sur la fréquence et la durée de participation à toute activité extérieure lors des loisirs durant l’âge adulte, ainsi qu’une description de chaque emploi tenu au cours de la vie. Une matrice emploi-exposition canadienne a été appliquée à chaque emploi afin d’assigner un niveau d’exposition professionnelle au soleil. Des indices cumulatifs de l’exposition au soleil basés sur le nombre d’événements récréatifs, la durée d’exposition professionnelle, ainsi qu’un indice d’exposition global ont été développés. La régression logistique a été utilisée pour estimer l’association entre chaque indice d’exposition et le CaP, en ajustant pour des variables de confusion potentielles. Résultats: Globalement, il n’y avait pas d’association entre chacun des indices d’exposition et le risque de CaP. Certaines tendances en accord avec un risque légèrement plus faible chez les hommes exposés au soleil ont été observées mais les résultats n’étaient pas statistiquement significatifs et il n’y avait pas de relation dose-réponse. Conclusion: Notre étude apporte peu de soutien à l’hypothèse d’une association entre l’exposition au soleil et le risque de développer un cancer de la prostate.

Social Media Use in Medical and Health Professional Education: Role of the Librarian on a Faculty Steering Committee

Objective: An interprofessional steering committee was created at Université de Montréal’s Faculty of Medicine to examine how social media are integrated in medical and health professional education in universities across the globe, and to propose a strategic plan for integrating social media in the Faculty’s various curricula. This presentation will summarize the steering committee’s work and describe the librarian’s contribution. Methods: The Committee’s project leader first conducted a literature search on best practices of social media in medical and health professional curricula. A reference website was then created (mse.med.umontreal.ca) to provide easy access to a large number of the articles and resources reviewed. A steering committee was constituted and 11 meetings were held over a 9-month period. The Committee comprised 18 members and included assistant deans, academic program directors, professors, communication advisors, undergraduate and graduate students and a librarian. An online survey on social media use by students and professors of the Faculty was conducted, ten pilot projects were put forward and a three-year strategic plan was proposed. Results: A total of 1508 students and 565 professors participated in the survey. Results showed that both groups had a strong interest in learning how social media could be integrated in academic and professional activities. Participants reported concern with risks associated with social media use and expressed the need for a Faculty policy and guidelines. The librarian’s contribution to the steering committee included: writing posts on the website’s internal blog, assisting in the design of the survey questionnaires and writing the final report’s survey results chapter. She also proposed two pilot projects: creating a social media learning portal and an altmetrics workshop. Conclusions: Based on the literature review and the survey results, the Committee affirmed the importance of integrating social media in the various study programs of the Faculty of Medicine. Despite the restricted timeline, this interprofessional steering committee was able to carry out its mandate because of the leadership and expertise of each of its members. As the librarian had the most experience with the use of social media in a professional context, her knowledge was instrumental in assisting the project leader in a group mainly composed of social media non-users.

The value of using short-format podcasts to enhance learning and teaching

This paper presents the findings of a podcasting trial held in 2007-2008 within the Faculty of Economics and Business at the University of Sydney, Australia. The trial investigates the value of using short-format podcasts to support assessment for postgraduate and undergraduate students. A multi-method approach is taken in investigating perceptions of the benefits of podcasting, incorporating surveys, focus groups and interviews. The results show that a majority of students believe they gained learning benefits from the podcasts and appreciated the flexibility of the medium to support their learning, and the lecturers felt the innovation helped diversify their pedagogical approach and support a diverse student population. Three primary conclusions are presented: (1) most students reject the mobile potential of podcasting in favour of their traditional study space at home; (2) what students and lecturers value about this podcasting design overlap; (3) the assessment-focussed, short-format podcast design may be considered a successful podcasting model. The paper finishes by identifying areas for future research on the effective use of podcasting in learning and teaching.

Use of essential and molecular dynamics to study gamma B-crystallin unfolding after non-enzymic post-translational modifications

Essential and Molecular Dynamics (ED/MD) have been used to model the conformational changes of a protein implicated in a conformational disease-cataract, the largest cause of blindness in the world-after non-enzymic post-translational modification. Cyanate modification did not significantly alter flexibility, while the Schiff's base adduct produced a more flexible N-terminal domain, and intra-secondary structure regions, than either the cyanate adduct or the native structure. Glycation also increased linker flexibility and disrupted the charge network. A number of post-translational adducts showed structural disruption around Cys15 and increased linker flexibility; this may be important in subsequent protein aggregation. Our modelling results are in accord with experimental evidence, and show that ED/MD is a useful tool in modelling conformational changes in proteins implicated in disease processes.
