Photosynthesis is a chemical process through which light energy is used to convert inorganic material (water and carbon dioxide) into organic molecules. Anaerobic photosynthesis, also known as anoxygenic photosynthesis, is the process by which certain bacteria use light energy to create organic compounds but do not adequately involve oxygen. In this experiment we are trying to influence photosynthesis (light and dark reactions: PS-I and PS-II by electron rich gadolinium/iodine complexes like Eovist and Isovue. We also performed X-ray and NIR reflection spectroscopy (NIRS) to measure Gd difusivity and PS-I/II infrared response. The results for X-ray (45kvp and 5 Mas ) …


An Investigation Of The Relationship Between Math Curricula And Students' College Readiness, Nancy A. Deluca Apr 2020

An Investigation Of The Relationship Between Math Curricula And Students' College Readiness, Nancy A. Deluca

Scholar Week 2016 - present

State learning standards with increased rigor have required higher levels of achievement from students on standardized tests, high-school grades, and national percentile ranks which are used for collegiate acceptance and course placement. As a result, preparation of students for standardized tests such as the ACT and SAT have become increasingly more challenging. The current quantitative, quasi-experimental study examined the relationship between the tangible math curricula used for instruction and students’ readiness for collegiate coursework. From sample sizes of 128 and 169 high-school students in two consecutive school years, there were several statistically significant relationship differences. Analysis of test results indicated …

Everyone Loves Gummi Bears! Removing The Intimidation Factor From Research Data Management With Yummy Fun., Dawn N. Cannon-Rech, Jeffrey M. Mortimore

Georgia International Conference on Information Literacy

How do you get students excited about research data management and attract over 70 participants to a voluntary workshop? How do you get Librarians excited about teaching a research data management workshop to undergraduates? With the promise of Gummi Bears and hands-on fun! During this workshop session, presenters will break down their experience overhauling a faculty workshop into an active learning session to expose students of all experience levels to basic research data management concepts and techniques. Presenters will walk participants through their design process from inception to delivery, highlighting how Gummi Bears lessened students’ intimidation with this complex topic …


Arduino Microcontrollers In The Classroom: Teaching How To Phrase Effective Science Questions And How To Answer Them With Original Data, Tony Dinsmore Jan 2020

Arduino Microcontrollers In The Classroom: Teaching How To Phrase Effective Science Questions And How To Answer Them With Original Data, Tony Dinsmore

Science and Engineering Saturday Seminars

Arduino microcontrollers in the classroom: teaching how to phrase effective science questions and how to answer them with original data. Prof. Tony Dinsmore, UMass Physics This workshop will develop course modules that address a challenge in the science curriculum: how do we teach basic problem-solving and curiosity-based research skills in a classroom setting? The standard science curriculum teaches concepts and theory quite well but leaves rather little opportunity for students to take the lead in designing and implementing their own investigations. The workshop will use the Arduino, an inexpensive microcontroller that is simple to set up. A huge range of …
