The purpose of this study is to develop a new approach and assess the application for the science and technology student-teachers to gain varied laboratory methods in science and technology teaching. It is also aimed to describe the computer-assisted POE application in the subject of "Photosynthesis-Light" developed in the context of…

It is relatively easy to incorporate plants into a curriculum and extend their use beyond the botany unit into other scientific arenas. There are numerous web-based resources for teachers, including the Human Flower Project (HFP) website, which offers numerous vignettes on all aspects of flowering plants. In addition to botany and invasive plant…

Many household gardeners accumulate considerable knowledge of plant biology through a range of informal learning sources. This knowledge seldom relates to school biology and is driven by interest, keen motivation and what is termed here "vital relevance." A small opportunity sample of 12 gardeners (6 M, 6 F) is interviewed in terms of…

Rigorous studies of the impact of digital games on student learning remain relatively rare, as do studies of games as supports for learning difficult, core curricular concepts in the context of normal classroom practices. This study uses a blocked, cluster randomized controlled trial design to test the impact of a digital game, played as homework…

Background: Education Standards highlight the importance of conceptual knowledge. Instructional tasks play a key role in biology instruction and offer learning opportunities for students. Tasks contain of a content and a demands part. Therefore, complexity and cognitive level are adequate variables to describe tasks and are assumed effective for…

Students' explanations of biological phenomena are frequently characterized by disconnects between levels and confusion of levels. The purpose of this research is to investigate the effects of a hands-on lab activity that aims at fostering the ability to reason across levels. A total of 197 students (18 years of age) participated in a randomized,…

The College of the Holy Cross offers a universal first-year program called Montserrat, in which first-year students participate in a living-learning experience anchored by a yearlong seminar course. The seminar courses are part of a thematic cluster of four to eight courses; students in the cluster live together in a common dormitory and…

The purpose of the study was to investigate the views of the prospective biology teachers about the field trip to Kazdagi National Park. Participants were 12 prospective Biology teachers studying in Necatibey Faculty of Education in Balikesir University, Turkey. A semi-structured interview form was used as a data collection instrument. Data were…

This essay contributes to a recent strain of research that questions clear-cut dichotomies between "scientists" and "artisans" in the early modern period. With a focus on the exploitation of agrarian resources, it argues for the appreciation of a more complex panorama of intersecting knowledge systems spanning from botany as…

Understanding flower structure is important from many perspectives such as keying out plants, understanding fruit structure, investigating pollinator biology and in plant breeding. Probably the most complicated parts of a flower are the female components (the gynoecium). Unfortunately, in many parts of the world, it is not possible for much of the…

This practical paper describes a novel fluorescence imaging experiment to study the three processes of photochemistry, fluorescence and thermal energy dissipation, which compete during the dissipation of excitation energy in photosynthesis. The technique represents a non-invasive tool for revealing and understanding the spatial heterogeneity in…

Maize ("Zea mays L.") is a model species well suited for the dissection of complex traits which are often of commercial value. The purpose of this research was to gain a deeper understanding of the genetic control of maize kernel composition traits starch, protein, and oil concentration, and also kernel weight and grain yield. Germplasm with…

Early involvement of students in hands-on research experiences are known to demystify research and promote the pursuit of careers in science. But in large enrollment departments such opportunities for undergraduates to participate in research are rare. To counteract such lack of opportunities, inquiry-based laboratory module in plant tissue…

The growth of a pine tree is examined by preparing "tree cookies" (cross-sectional disks) between whorls of branches. The use of Christmas trees allows the tree cookies to be obtained with inexpensive, commonly available tools. Students use the tree cookies to investigate the annual growth of the tree and how it corresponds to the number of whorls…

Ecofeminist science pedagogy has received scant attention in the educational literature. This article presents an ecofeminism framework for the teaching of college-level botany courses. This didactic approach emphasizes women's experiences, appreciation for the accomplishments of women in science, connection to real world learning exercises, group…
