The Impact of a Flipped Classroom on Student Achievement in Mathematics, Science and Physical Education Classrooms

This study was designed to examine the effects of the flipped classroom model. Our study was conducted in Physical Education, Mathematics, and Science classrooms in the Bismarck Public Schools district. The participants were in both the middle and high school levels within the same school district. Data collection methods included a pre-assessment survey, written assignments, a student behavior checklist, and a post-assessment survey. The results of our study showed that students enjoyed learning with the flipped classroom method, completion rates were higher than previously observed, and students were successful at mastering classroom content. According to our student survey, the main benefits to the flipped classroom, were the ability to view lessons without distractions and to view them multiple times. We will continue to look into the benefits of the flipped classroom through the analysis of standardized test scores and classroom assessments

Epstein-Barr virus:more than 50 years old and still providing surprises

It is more than 50 years since the Epstein–Barr virus (EBV), the first human tumour virus, was discovered. EBV has subsequently been found to be associated with a diverse range of tumours of both lymphoid and epithelial origin. Progress in the molecular analysis of EBV has revealed fundamental mechanisms of more general relevance to the oncogenic process. This Timeline article highlights key milestones in the 50-year history of EBV and discusses how this virus provides a paradigm for exploiting insights at the molecular level in the diagnosis, treatment and prevention of cancer
