Triterpenic acids (TA), a class of triterpenoids, are widely distributed as secondary metabolites in plants. They have a pentacyclic structure and show high structural diversity. In this work, a simple but efficient method for extraction and detection of TA derivatives from apple peels is described. The method is technically straightforward and…

Botanical literacy is an important competency preservice biology teachers must have to support contextual and sustainability-oriented science learning. This study aims to describe the profile and views of botanical literacy of preservice biology teacher students in their final year of study. The study was conducted at one of the state Islamic…

This study contributes to the research in Early Childhood Education for Sustainability (ECEfS) by exploring a case study of two Western Australian early childhood education classes who welcomed an Indigenous Elder to share their expertise about the native plants in the schools' bush space. The findings from this study demonstrate the impact…

Antioxidants are molecules that act against free radicals, and this effect can bring many benefits to health and society. Antioxidants can be found in various matrices of nature, such as fruits and plants. Some studies have shown that "Rhizophora mangle," a typical mangrove plant, is rich in antioxidants. People report its use for…

A new organic chemistry experiment aimed to separate the chlorophyll precursor in plant seeds by column chromatography is described. The primary pedagogical goal in developing this experiment is to establish a simple and interesting chromatographic separation to demonstrate basic concepts and the standard procedure for this important lab…

Plant leaves are green because they contain the green photosynthetic pigments, chlorophylls a and b. Popular science literature, and sometimes even textbooks, state that the greenness is caused by reflection of green light by chlorophyll. In the present study, we compared the reflectance spectra of green leaves to yellow or white leaves of the…

This paper describes the master course design process at the largest institution of higher education in Colorado, USA. The master course design process demonstrated principles of backwards design and employed a team-based approach to course development. The course map was the primary vehicle for communicating the design of the course during…

With the onset of global change, forest species diversity has declined in recent decades as pristine habitat in biological hotspots rapidly diminishes. Many carbon mitigation efforts directed at decreasing emissions from forest degradation and destruction assume that faunal biodiversity will benefit from such efforts. Yet, conservation of faunal…

Out-of-school science education is important for students' emotional outcomes, such as their interest in science. Not all students, however, have access to real outdoor environments for hands-on learning. To address this issue, live streaming technology allows for real-time interaction and video-based instruction, which can enhance students'…

An important educational goal is enabling students to learn scientific concepts. The scientific concepts learned in class are developed within students' cognitive structures. Despite the successful application of Semantic Network Analysis (SNA) to study these cognitive structures, there has been limited examination of students' concept networks…

This study responds to the need to produce inviting learning environments that help to build intentional science learning in early childhood education. We present a free-choice science learning environment on plant diversity in the fall. From the moment it was implemented, we analyzed whether children of different educational levels acted in…

Course-based undergraduate research experiences (CUREs) provide students with valuable opportunities to engage in research in a classroom setting, expanding access to research opportunities for undergraduates, fostering inclusive research and learning environments, and bridging the gap between the research and education communities. While…

Education that covers topics such as climate change is critical to developing future scientists and researchers. Facilitating students' recognition of climate change as it occurs in their community can strengthen engagement with the content. Here, we highlight our work in developing a large-scale activity that introduced many facets of climate…

Indonesia's rich plant biodiversity and cultural heritage are closely reflected in traditional life cycle ceremonies--such as birth, marriage, and death--which often involve specific plant species. Ethnobotany, the study of human-plant interactions, serves as a bridge between traditional knowledge and modern science. This descriptive qualitative…

Following the switch to remote online teaching in the wake of the COVID-19 pandemic, the plant taxonomy course at the University of Georgia (UGA) switched to iNaturalist for the specimen collection portion of the course requirements. Building off extant rubrics, the instructors designed project guidelines for a fully online plant collection…
