When student projects require an analytical step that is robust and sufficiently selective, high performance thin layer chromatography (HPTLC) is a method to be considered. However, for student laboratories not equipped for HPTLC, sample application as a sharp narrow band is a hurdle. The low eluting power of water on reversed phase plates can be…

Object-based learning is an approach that aims to foster observational skills and sensory awareness. Paradoxical plant objects that do not lend themselves to all-too-easy explanations and interpretations can be used to practice the search for ecological explanations and the formation of evolutionary hypotheses. They can be the basis of…

In this article, I use aerial footage of the Amazon as a guiding thread to argue that the sublime is the most fitting concept to describe our aesthetic response to the representation of Amazonian nature in cinema. In my discussion of rainforest aesthetics, I focus on two Brazilian films, made ten years apart: Glauber Rocha's short "Amazonas,…

Secondary metabolite compounds contained in each plant genus have certain characteristics, which is true also of the flavonoid in the genus "Artocarpus." In the experiment described here, third-year undergraduate students performed the isolation and characterization of cycloartocarpin from the roots of "Artocarpus altilis"…

This qualitative, exploratory, comparative case study examined plant-based innovations in Title I PK12 public-school nutrition programs (PSNPs) in the context of the School Health Index (SHI) and Whole School, Whole Community, Whole Child (WSCC) objectives. The study explored the perceptions of PK12 superintendents, school board members, nutrition…

Teaching about biodiversity and its conservation could be an effective way to teach the importance of different species and human dependence on ecological support systems. This study compares the effectiveness of a digital and a paper-based dichotomous identification key for teaching pre-service teachers about plant species diversity. Twenty-four…

The exploitation of animals for human purposes raises several ethical concerns in the educational realm that ought to be carefully dealt with. Derived from the content analysis of sample of 39 Portuguese secondary and high school textbooks, this study aims to understand how factory-farmed animals are represented within the following themes: food…

The iNaturalist application has been gaining traction in both biodiversity research and education. Increasingly more research is being carried out, looking into using the iNaturalist application in biology education, to promote biodiversity and educate students about this topic. We used the PRISMA systematic literature review method to examine…

This study explores the importance of scientific observation in primary education, highlighting how the use of observation sheets can facilitate the acquisition of knowledge and the development of students' observation skills. In the research, 153 second-grade students were divided into three experimental groups, each group observing a woody plant…

Basic quantitative and population genetics topics are typically taught in introductory plant breeding courses and are critical for success in upper-level study. Active learning, including simulations and games, may be useful for instruction of these concepts, which rely heavily on theory and may be more challenging for students. The statistical…

We examined the sophistication of middle school students' mechanistic explanations of genetics phenomena and how they interact with a technology-based explanation tool as they articulate and organize their ideas about the phenomena. We coordinated curriculum and assessment design frameworks to develop a middle school curriculum unit that engages…

A comprehensive experiment for third-year undergraduate students in pharmaceutical engineering is described. Students had previously completed courses in analytical chemistry, chemistry of natural products, and bioseparation engineering and had background knowledge in purification, quantitative analysis, packed column chromatography,…

It has been speculated that most people have plant blindness, meaning plants go unnoticed by the majority of the population. This study sought to combine the knowledge of multiple disciplines to determine evidence of plant blindness through children's drawings. To do this, third-grade students were introduced to native prairie and wetland plants…

Despite the importance of bees, there is a gap in the public's understanding of them. To help address this gap, we developed the outreach tool Experience Bees, a series of simple learning and hands-on activities to teach community members about bees and their importance in our landscapes. Program evaluation showed that participants learned about…

The aim of this study is to present the details of a practice that is carried out within the scope of Community Service Practices Course from a scientific perspective. And also to investigate the views of the pre-service teachers related to the topic. Research design is determined as a case study method. For the data collection, interview method…
