Processus décisionnel des parents concernant la vaccination de leur nourrisson, selon leur génération d’appartenance

Résumé : Malgré le fait que la vaccination soit reconnue comme l’une des mesures de santé publique les plus efficaces, elle est perçue comme non sécuritaire et non nécessaire par un nombre grandissant de parents. Dans ce contexte, la compréhension du processus décisionnel des parents par rapport à la vaccination de leur enfant serait aidante. Le but de cette étude est d’explorer le processus décisionnel des parents concernant la vaccination de leur nourrisson, selon leur génération d’appartenance, soit la génération X ou Y. Une étude de cas descriptive et comparative a été réalisée avec des entrevues semi-structurées ainsi qu’une analyse des sources d’informations consultées par les participantes. Les mères ont été sélectionnées selon leur intention de vaccination pour leur enfant. Les données ont été codifiées et analysées de façon systématique et rigoureuse au niveau intra-cas et inter-cas, co-analysées et ensuite validées avec les participantes. Quatre mères dans chaque génération ont été interviewées, dont trois participantes par génération à deux reprises. Le processus décisionnel est similaire d’une génération à l’autre. Les composantes du processus sont l’attitude initiale envers la vaccination, le processus cognitif, la recherche d’information, la décision, l’acte et l’évaluation rétrospective de l’expérience vécue. Toutes ces composantes sont influencées par des facteurs intrinsèques et extrinsèques. Certaines trouvailles de cette étude ont peu été documentées dans la littérature telles que la perception positive envers la vaccination, l’inconscience du processus, l’importance du déclencheur et le fait de saisir le moment opportun. Malgré la rigueur de cette étude, la principale limite est la saturation des données qui n’a possiblement pas été atteinte pour tous les aspects du processus décisionnel. Même si la norme sociale est favorable à la vaccination, aucune participante n’avait consciemment réfléchi à l’immunisation de son enfant jusqu’à ce qu’un déclencheur soit introduit. Ceci soulève l’enjeu et l’impact de la transmission de l’information adéquate, au moment opportun, et du soutien donné aux parents qui naviguent dans ce processus.

Compétences en littératie visuelle chez les étudiantEs en biologie au niveau collégial: bilan des apprentissages selon des activités digitales ou des activités de dessins à la main

This study examines the role of visual literacy in learning biology. Biology teachers promote the use of digital images as a learning tool for two reasons: because biology is the most visual of the sciences, and the use of imagery is becoming increasingly important with the advent of bioinformatics; and because studies indicate that this current generation of teenagers have a cognitive structure that is formed through exposure to digital media. On the other hand, there is concern that students are not being exposed enough to the traditional methods of processing biological information - thought to encourage left-brain sequential thinking patterns. Theories of Embodied Cognition point to the importance of hand-drawing for proper assimilation of knowledge, and theories of Multiple Intelligences suggest that some students may learn more easily using traditional pedagogical tools. To test the claim that digital learning tools enhance the acquisition of visual literacy in this generation of biology students, a learning intervention was carried out with 33 students enrolled in an introductory college biology course. The study compared learning outcomes following two types of learning tools. One learning tool was a traditional drawing activity, and the other was an interactive digital activity carried out on a computer. The sample was divided into two random groups, and a crossover design was implemented with two separate interventions. In the first intervention students learned how to draw and label a cell. Group 1 learned the material by computer and Group 2 learned the material by hand-drawing. In the second intervention, students learned how to draw the phases of mitosis, and the two groups were inverted. After each learning activity, students were given a quiz on the material they had learned. Students were also asked to self-evaluate their performance on each quiz, in an attempt to measure their level of metacognition. At the end of the study, they were asked to fill out a questionnaire that was used to measure the level of task engagement the students felt towards the two types of learning activities. In this study, following the first testing phase, the students who learned the material by drawing had a significantly higher average grade on the associated quiz compared to that of those who learned the material by computer. The difference was lost with the second “cross-over” trial. There was no correlation for either group between the grade the students thought they had earned through self-evaluation, and the grade that they received. In terms of different measures of task engagement, there were no significant differences between the two groups. One finding from the study showed a positive correlation between grade and self-reported time spent playing video games, and a negative correlation between grade and self-reported interest in drawing. This study provides little evidence to support claims that the use of digital tools enhances learning, but does provide evidence to support claims that drawing by hand is beneficial for learning biological images. However, the small sample size, limited number and type of learning tasks, and the indirect means of measuring levels of metacognition and task engagement restrict generalisation of these conclusions. Nevertheless, this study indicates that teachers should not use digital learning tools to the exclusion of traditional drawing activities: further studies on the effectiveness of these tools are warranted. Students in this study commented that the computer tool seemed more accurate and detailed - even though the two learning tools carried identical information. Thus there was a mismatch between the perception of the usefulness of computers as a learning tool and the reality, which again points to the need for an objective assessment of their usefulness. Students should be given the opportunity to try out a variety of traditional and digital learning tools in order to address their different learning preferences.

The Role of Teacher Presence during Computer Supported Online Collaborative Sessions in an Adult Education Course.

The convenience sample for this study was taken from an A.E.C. (Attestation of Collegial Studies) Communication course of the Continuing Education Technical Support Program. A key component of this course competency is for students to develop the skill to write business letters for various purposes and to apply the three-step writing process during the crafting of the correspondence. This is achieved with a number of writing assignments which are carried out by students working in teams and completing the writing assignments out-of-class. the out-of-class work was convened using the PrimaryPad program to complete two of the writing assignments, which formed the basis of the research. This research uses a case study design that employed a repeated measures method with two conditions (teacher scaffolding vs. no teacher scaffolding). The possibility of an order effect was controlled for by using a counterbalancing of treatment design. A post-treatment questionnaire was used to gather descriptive statistics.
