Effective intervention procedures are essential to breaking the cycle of school failure. Tobin and Sprague (2000) conducted a review of strategies that have shown to be effective with youth served in alternative education settings. Among those were instructional strategies, including tutoring. ClassWide Peer Tutoring (CWPT) is a well-researched…

Exciting news is emerging that could change the lives of many parents of children and adolescents with autism. Extreme tantrums often "run their lives," according to Dr. Lawrence Scahill, Professor of Nursing and Child Psychiatry at the Yale Child Study Center in New Haven, Connecticut. As the Director of Yale's Research Unit on Pediatric…

This article offers a case study of the evaluation of a redesigned and redeveloped laboratory-based cell biology course. The course was a compulsory element of the biology program, but the laboratory had become outdated and was inadequately equipped. With the support of a faculty-based teaching improvement project, the teaching team redesigned the…

This article examines the use of institutional research data on tertiary academic success of students in the first-year Biology program at the University of Canterbury in relation to their secondary school performance in English, Mathematics with Statistics, Biology and Chemistry. This study was commissioned by the School of Biological Sciences to…

No significant difference in beginning ninth-grade pretest compared to ending ninth-grade posttest comparisons of American History t(17) = 0.34, p = 0.37 (one-tailed), d = 0.09, English t(17) = 1.40, p = 0.09 (one-tailed), d = 0.34, and Biology (t(17) = -1.58, p = 0.07 (one-tailed), d = -0.22, course grade scores were observed for students…

Active-learning techniques have been advocated as a means to promote student engagement in lower-division biology courses. In this case study, mini-lectures in combination with active-learning activities were evaluated as strategies to promote a culture of learning and participation in a required botany course. These activities were designed to…

In order to understand and resolve the disproportionate number of women in the sciences it is necessary to look at historical educational trends. Through the ages there is evidence of a "pendulum effect" where there have been major shifts focusing science education either on male or females. To be able to realistically establish sustainable equity…

Chemistry has become increasingly multidisciplinary. Starting in middle school and high school, however, the different disciplines are taught as distinct subjects and little effort is made to emphasize overlapping concepts. Development of innovative approaches to teaching science through the integration of technology is needed to provide students…

This study examined the effects of professional development integrating academic literacy and biology instruction on science teachers' instructional practices and students' achievement in science and literacy. The intervention consisted of 10 days of professional development in Reading Apprenticeship, an instructional framework integrating…

A major finding of comparative genomics and developmental genetics is that metazoans share certain conserved, embryonically deployed signaling pathways that instruct cells as to their ultimate fate. Because the DNA encoding these pathways predates the evolutionary split of most animal groups, it should in principle be possible to clone…

"Drosophila melanogaster" is a commonly utilized organism for testing hypotheses about inheritance of traits. Students in both high school and university labs study the genetics of inheritance by analyzing offspring of appropriate "Drosophila" crosses to determine inheritance patterns, including gene linkage. However, most genetics investigations…

Purpose: Airway drying is detrimental to phonation and is posited to exacerbate vocal fatigue. However, limited research has demonstrated the adverse phonatory effects of dehydration in speakers reporting vocal fatigue. We compared the negative phonatory consequences of short-term oral breathing at low, moderate, and high humidity in individuals…

Discovery of RNA-mediated interference (RNAi) is widely recognized as one of the most significant molecular biology breakthroughs in the past 10 years. There is a need for science educators to develop teaching tools and laboratory activities that demonstrate the power of this new technology and help students to better understand the RNAi process.…

The 5E teaching model provides a five step method for teaching science. While the sequence of the model is strictly linear, it does provide opportunities for the teacher to "revisit" prior learning before moving on. The 5E method is described as it relates to the teaching of aerobic cell respiration.

Hundreds of financial conflicts of interest among university researchers have not been investigated by the National Institutes of Health, an agency that should police them, according to a new audit report. The report, by the inspector general of the Department of Health and Human Services--NIH's parent agency--describes a dysfunctional system that…
