Because students in middle school through high school demonstrate persistent alternative conceptions regarding atoms and cells and their functional relationships, it is important to investigate ways...
In this study, the quality of small group discussions stimulated by concept cartoons on the topic of cell division was examined in a class of sixteen high school agriculture biology students. Two...
Although many teachers consider dissection an important educational tool, it is mainly used to reinforce information previously gained by studying anatomy and physiology. Rarely is inquiry-based...
In this study, a design-based research approach was used in the creation of data-rich problem (DRP) tasks intended to support students constructing knowledge about food webs and ecosystem dynamics...
The Conceptual Inventory of Natural Selection (CINS) developed by Dianne Anderson and Kathleen Fisher is a valuable tool to measure how well college students understand natural selection. However...
The conceptual Inventory of Natural Selection was first published in 2002 (Anderson & Fisher, 2002). Recent research by Nehm & Schonfeld (2008) has raised concern as to whether or not the Conceptual...
The purpose of this study was to determine the existence of high school students’ alternative conceptions regarding stem cells, and explore the underlying themes and contexts of these conceptions...
This study investigated the use of biological concept cartoons in discussions as a strategy to actively engage low performing (LP) seventh grade students to stimulate the formation of more...
In this study a design-based research approach was applied in the creation of a data-rich problem (DRP) task intended to improve student achievement in cellular respiration at the ecosystem level; an...
Evolution, by means of natural selection, is a core concept central to understanding biology. A hurdle to effective natural selection instruction is the wide range of alternative conceptions held by...
Concepts in evolution are introduced at the middle school level, but are taught in more depth at the high school level. Students come in with prior conceptions of evolution that influence student...
Higher education science researchers have postulated that understanding variation is a threshold concept in biology. Variation is evident in all living organisms yet is often overlooked as important...
Although the use of technology in biological career paths is increasing globally, studies indicate that United States undergraduate biology students are not prepared for this technologically advanced...
A swarm of the δ-proteobacterium Myxococcus xanthus is a distributed system; a population of superposable automata whose distribution is transparent so that it appears as one machine. These swarms...
Macrophages are able to polarize from a basal, naïve state to an M1 or M2 phenotype. M1 pro-inflammatory macrophages are characterized by recognizing and eliminating abnormal cells, while M2 anti...
The human microbiota is a thriving ecosystem that has remained a great mystery, as we have yet to develop a complete understanding of its complex nature and capabilities. Nonetheless, numerous studies...
Antibiotic resistance among Gram-positive bacteria is a serious global health threat. Vancomycin-resistant enterococci (VRE) are especially concerning since they are susceptible to few if any...
The ability to structurally engineer viral nanoparticles makes them a useful platform for targeted drug delivery. The procapsid of bacteriophage lambda is one such structure. This hollow icosahedral...
This study focuses on the phylum Mollusca from Hannibal Bank in Panama. Through DNA sequencing and phylogenetic analyses, the biodiversity and evolutionary history of mollusks were evaluated. The...
Evaluating predatory-prey relationships is critical for understanding the dynamics of ecosystems and implementing effective conservation efforts. I investigated whether Neotropical mammalian predators...
Hannibal Bank is a seamount-like feature known for its high productivity and biodiversity that is located in an UNESCO World Heritage Site off the Pacific coast of Panama. The biodiversity and...
Zika virus (ZIKV) is a member of the Flaviviridae virus family and as of February 2016 has been declared a global public health emergency by the World Health Organization. Understanding the T cell...
Hannibal Bank is a biodiversity hotspot off the Pacific coast of Panama. Using the AUV SeaBED, 12 photo-transects of the seafloor systematically captured over 21,712 images during a research cruise in...
The idea for this study came from the shortage of research that has been done to understand the evolution instruction provided by new secondary education teachers. A lack of training in teachers can...
