This study explores the associations of ethnicity and perceived challenge with high-school students' academic engagement and perceived competence in science. Data were collected through a variant of the Experience Sampling Method in which participants reported on their levels of engagement, perceived competence, and challenge while in science…

I have developed a new teaching and learning model called AAAW, which stand for Analyze, Acquire, Apply and Write. This model grows from action research and unique experience in teaching a biochemistry course to high school students who are talented in math and science. In this model, students first "Analyze" lab data to generate…

The internationally recognized Illinois Mathematics and Science Academy (IMSA) develops creative, ethical leaders in science, technology, engineering and mathematics. As a teaching and learning laboratory created by the State of Illinois, IMSA enrolls academically talented Illinois students in grades 10 through 12 in its advanced, residential…

Plasticizers are chemical additives that enhance plastic flexibility. They are ubiquitous environmental contaminants and are commonly found in river and lake waters (Fromme et al 2002). The present study aimed to investigate the effects of a water-soluble plasticizer, dibutyl phthalate (DBP) on developing Medaka ("Oryzias latipes") embryos. Three…

The effectiveness of five different enzymes as treatments against Staphylococcus biofilm growth was measured in the presence of antibiotics and alone. Protease was the least effective enzyme in biofilm removal with all antibiotics, and pectinase was the most effective with dicloxacillin and clindamycin. Also, dicloxacillin was the most effective…

As Director of the Carol Martin Gatton Academy of Mathematics and Science in Kentucky for the past four and a half years, the author has had the distinct pleasure of leading an amazing group of students and staff in a residential program for high school juniors and seniors interested in advanced STEM careers. The years he has at the Gatton Academy…

In conjunction with an NSF-funded mentoring program that partners University of Utah engineering professors and their undergraduate and graduate students with high school students from several Salt Lake City high schools that have a high percentage of low income and ethnic minority students, the Academy for Math, Engineering, and Science (AMES)…

Roughly 80% of the math and science schools under the National Consortium for Specialized Secondary Schools of Mathematics, Science, and Technology (NCSSSMST) umbrella are non-residential programs, with about 18% residential and 2% both residential and nonresidential. Now numbering 16 (with the Tennessee Governor's Academy closing May 2011), the…
