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...
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...
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...
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 applied in the creation of a data-rich problem (DRP) task intended to improve student achievement in cellular respiration at the ecosystem level; an...
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...
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...
Previous literature in volleyball biomechanics highlighted jump height and ball speed as key determinants for the success of regular spikes. To further current research and provide athletes and...
Looked at the rates of depression, anxiety and stress using the DASS-21 in college athletes during COVID-19. Looked at the difference between males and females over time. Results show there was no...
Evolution by natural selection is foundational in biology, yet decades of science education research have shown that common alternative conceptions often persist after college biology instruction...
To analyze the mental health status of student-athletes following COVID-19 induced social isolation, perceptions of depression, anxiety, and stress were measured before and after athletes return to...
Performance block is a blanket term that research is trying to propose to replace sport specific terms such as yips, mental block, or lost move syndrome. Though symptoms may present slightly different...
Comparing the effects of a percent based training program against a velocity based training program on the outcomes of strength, power and speed. Also assessing the reliability of load-velocity...
Peak ground reaction force (GRF) is one variable that has been studied in the lower extremity to determine the amount of force generated by the drive leg and stride leg of the pitcher. Studies suggest...
The current project was focused on distance running performance, investigating different factors that affect it. The main focus was on neuromuscular capacity and certain muscle power factors. The...
It has been well documented that the San Diego area has seen an increase in bacteria in its waterways. Due to its close negative correlation with human health, it is important to attempt to address...
