Chlorophyll, the most abundant pigment in nature, is degraded during normal plant growth, when leaves change color, and at specific developmental stages. Chlorophyllase catalyzes the first chemical reaction in this process, that is, the hydrolysis of chlorophyll into chlorophyllide. Here, we describe a series of laboratory sessions designed to…

Comprehensive measurement of gene expression using high-density nucleic acid arrays (i.e. microarrays) has become an important tool for investigating the molecular differences in clinical and research samples. Consequently, inclusion of discussion in biochemistry, molecular biology, or other appropriate courses of microarray technologies has…

Analogical reasoning is integral to everyday living. The diversity associated with a coral reef provides a familiar model for initiating discussions focusing on cultural diversity and gender of past and present scientists with non-western science endeavors. These concepts are strengthened through the use of scientific biographical and historical…

This seven to eight week hands-on Marine Debris Clean-up Project used a service project to provide an introduction of marine science ecology, watershed interrelationships, the scientific method, and environmental stewardship to 8th grade middle school students. It utilized inquiry based learning to introduce marine debris sources and impacts to…

This study examined the role of social support in promoting quality of life in the aftermath of critical incidents involvement. Participants were a sample of 586 Italian rescue workers. Structural equation modelling was used to test the social support deterioration deterrence model. Results showed that the impact of critical incident involvement…

We examined relationships among fatigue, sleep quality, and effort-reward imbalance for learning in school children. We developed an effort-reward for learning scale in school students and examined its reliability and validity. Self-administered surveys, including the effort reward for leaning scale and fatigue scale, were completed by 1,023…

The 6th Annual Conference of the National Academy for the Integration of Research, Teaching and Learning (NAIRTL) and the 4th Biennial Threshold Concepts Conference was held at Trinity College Dublin, Ireland, on June 27-29, 2012. The NAIRTL is a collaborative initiative between University College Cork, Cork Institute of Technology, National…

Autism spectrum disorder (ASD) affects an estimated 1% of children in the United States and yet many fundamental questions about the biology of ASD, potential risk factors, effective treatments and interventions, and impacts throughout life remain unanswered. Important advances have been made in understanding the complexity of ASD, but additional…

Restricted and repetitive behaviors (RRBs) are a core feature of autism spectrum disorders. They constitute a major barrier to learning and social adaptation, but research on their definition, cause, and capacity for change has been relatively neglected. The last decade of research has brought new measurement techniques that have improved the…

Providing equitable learning opportunities for all students has been a persistent issue for some time. This is evident by the science achievement gap that still exists between male and female students as well as between White and many non-White student populations (NCES, 2007, 2009, 2009b) and an underrepresentation of female, African-American,…

The 2012 National Survey of Science and Mathematics Education was designed to provide up-to-date information and to identify trends in the areas of teacher background and experience, curriculum and instruction, and the availability and use of instructional resources. A total of 7,752 science and mathematics teachers in schools across the United…

Describes an experiment, easily repeated in the classroom, designed to determine whether members of the species Drosophila melanogaster show selective preference in choice of mates. (PEB)

This manual has been produced for use in a four-week training program developed by University of Rhode Island fisheries educators for the training of United States citizens in the duties and responsibilities of observers placed on foreign fishing vessels operating in the Fisheries Conservation Zone in the Atlantic Region. The program combines…

This digest is intended to be used in conjunction with the text Manual for the Training of United States Fisheries Observers - Atlantic Region. The digest contains five elements; an organization of the training program into sections that allow cumulative learning experience; provides a chronology of these sections to provide optimum coverage and…
