In classic visual search, observers typically search for the presence of a target in a scene or display. In foraging tasks, there may be multiple targets in the same display (or "patch"). Observers typically search for and collect these target items in one patch until they decide to leave that patch and move to the next one. This is a…

Research into seed germination classroom activities has been common in the last few decades. Didactic proposals have generally focused on the implementation of guided activities in a specific educational stage and context, and an evaluation of the results. However, it is not evident that students approach seed and germination concepts with a…

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…

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…

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…

In the course of combining the Sustainable Development Goals (SDGs) with the science education curriculum, the relevance of the micro- and macroalgae in education is based on the biotechnological future-oriented significance and the ever-growing trend toward plant-based nutrition. So, the micro- and macroalgae are finding their way onto the food…
