In Vitro Technology in Plant Conservation: Relevance to Biocultural Diversity.

Plant diversity is critical to the functioning of human societies, and evidence shows that plant conservation success is driven by integrative approaches that include social and biological factors. Plants have a unique capacity to reproduce asexually, and propagation practices can yield large numbers of plantlets. These plantlets can be used in several ways to fulfil conservation goals including the repopulation of regions with declining densities of threatened species that hold cultural meaning. However, the potential of in vitro technologies in the conservation of plants that hold cultural meaning is understudied. In this paper we focus upon the roles of in vitro technologies in the conservation of plants relevant to biocultural environments and provide an overview of potential knowledge gaps at the interface of in vitro and plants used traditionally, including those meaningful to Indigenous Peoples. We conclude that in vitro technologies can be powerful tools in biocultural conservation if they are deployed in a manner respectful of the socio-cultural context in which plants play a role, but that further research is needed in this regard. We suggest several epistemological points to facilitate future research.

Barriers and Facilitators to Intake of Dairy Products in Adolescent Males and Females With Different Levels of Habitual Intake.

Background: Dairy products and alternatives can contribute to overall good health including positive body composition and decreased adiposity; however, these foods are grossly underconsumed by youth, and worldwide, almost 25% of children are overweight or obese. Objective: The study investigated the barriers and facilitators toward dairy consumption by Grade 7 youth. Methods: Thirty 50-minute, audio-recorded focus groups were conducted with 134 students in eight Grade 7 classes across 5 elementary schools. Focus groups were led by trained facilitators in the elementary schools and participants were separated based on dairy consumption and gender. Recorded data were transcribed and thematically analyzed using qualitative analysis software to identify themes related to barriers and facilitators to dairy product intake by each gender. Results: Factors considered important by males and females across different levels of habitual intake include personal knowledge about dairy products and misconceptions regarding dairy foods and their associated health benefits; food characteristics, including taste; personal behaviors such as habits or routines including dairy products; social environments including parental and peer influence; physical environments factors such as availability and skipping meals; and the convenience of dairy products. Interestingly, only males noted sports as a positive influence for dairy product intake. Also, there were differences in the way males and females perceived dining out as affecting their dairy intake. Conclusion: Results suggest several potential factors that nutrition education interventions aiming to increase dairy consumption could target.

Perceptions and use of sources of health knowledge by young adolescents.

BACKGROUND: Understanding how adolescents acquire health knowledge and where they currently seek answers to health-related questions may facilitate the development of interventions that will be both engaging and effective, and may help to improve health over the short- and long-term. OBJECTIVE: The present study sought to investigate the perception and use of sources of health knowledge by young adolescents as stratified by gender. METHODS: Thirty 50-min long focus groups were conducted with 143 participants. Focus group questions were built around the following three main categories: sources of knowledge, including preferred sources, sources accessed for general health, and sources accessed for personal/sensitive health; health information and behaviour change, including characteristics of health knowledge presentation that have influenced behaviour change; and learning preferences to promote behaviour change. Content analysis of focus group transcripts was performed. RESULTS: The use of sources of health knowledge was similar between genders, with some differences noted between sources accessed for general as compared to personal health questions. As well, motivation appeared to be the primary influence of health behaviour change, with knowledge being reported as both as positive and neutral influence, most notably in the areas of diet and exercise. Lastly, adolescents reported several characteristics of health knowledge presentation that they felt would motivate positive behaviour change, including engaging and participatory activities. CONCLUSION: These results should be considered in the development of interventions to improve health-related behaviour in adolescents, although future research to quantify the use of sources of health knowledge by this population is recommended.

Evidence-informed strategies for undergraduate nutrition education: a review.

This review focuses on evidence-informed strategies to enhance learning in undergraduate nutrition education. Here, we describe the general shift in undergraduate education from a teacher-centered model of teaching to a student-centered model and present approaches that have been proposed to address the challenges associated with this shift. We further discuss case-based, project-based, and community-based learning, patient simulation, and virtual clinical trials as educational strategies to improve students' critical thinking and problem-solving skills; these strategies are well suited to the teaching of undergraduate nutrition. The strategies are defined, and we discuss the potential benefits to students and how they can be applied specifically to the teaching of undergraduate nutrition. Finally, we provide a critical analysis of the limitations associated with these techniques and propose several directions for future research, including research methodologies that may best evaluate teaching strategies in terms of both teaching and learning outcomes. Consideration of these evidence-informed strategies is warranted, given their ability to encourage students to develop relevant skills that will facilitate their transition beyond the university classroom.

A guide to using case-based learning in biochemistry education.

Studies indicate that the majority of students in undergraduate biochemistry take a surface approach to learning, associated with rote memorization of material, rather than a deep approach, which implies higher cognitive processing. This behavior relates to poorer outcomes, including impaired course performance and reduced knowledge retention. The use of case-based learning (CBL) into biochemistry teaching may facilitate deep learning by increasing student engagement and interest. Abundant literature on CBL exists but clear guidance on how to design and implement case studies is not readily available. This guide provides a representative review of CBL uses in science and describes the process of developing CBL modules to be used in biochemistry. Included is a framework to implement a directed CBL assisted with lectures in a content-driven biochemistry course regardless of class size. Moreover, this guide can facilitate adopting CBL to other courses. Consequently, the information presented herein will be of value to undergraduate science educators with an interest in active learning pedagogies.
