Disscusion - Essay Example The CDF (2014) affirms that no cases of the new H7N9 virus have been detected in people and birds within the United States. A number of avian influenza viruses have been able to cross the species barrier on a few occasions with the effect of having a varying impact on human health. Kreijtz et al, (2013), point out that the majority of the humans infected with avian virus have presented with severe viral pneumonia before they eventually became critically ill. These symptoms are supported by findings by the CDC (2014) which reports that while some relatively mild cases of human H7N9 infection have been reported with most of these patients being diagnosed as having severe respiratory illnesses, an alarming one-third of infections result in death. The pandemic potential of the H7N9 virus is evidenced by the fact that the estimated mortality rate of one-third of infected patients provided by the CDC (2014) is found to be similar to the results of an epidemiologic study that was conducted on 82 confirmed cases of persons infected with the H7N9 virus in china by Li et al. (2013). In the study, it was found that the mortality rate for the disease was at about 21%, however, Li et al, (2013), highlighted the fact that this percentage was quite likely to increase as most of the patients in the study who were confirmed as having the H7N9 virus infection remained critically ill. Attempts to try and control the spread of the avian A (H7N9) virus by the controlled culling of birds in affected areas might not be particularly successful as is shown by the results of a study conducted by Olson et al, (2013). In the study, the researchers established that controlling human infection with the H7N9 avian influenza subtype by the culling of birds might prove to be quite challenging as a result of the probability that some of the infected domestic flocks might be asymptomatic. Olson et al, (2013), also

Cooperative learning groups - Essay Example The researcher states that scholars, educators, and school officials have become more and more interested in students’ performance in mathematics. Several studies have reported that, starting from middle school, girls are prone to develop more unconstructive attitudes towards math and score low on standardized exams. Moreover, a significant relationship has been found between performance and attitudes. Certain factors that are associated with performance of students in math comprise learning experiences, sense of belongingness, racial or ethnic affiliation, gender, self-worth, stereotyping and attitudes. National Council of Teachers of Mathematics claimed that instruction, competent educators, high expectations and equity should be awarded to every learner. By doing so, performance of students in math has a better chance to progress. The topics crucial for every student are usually included in Geometry, Algebra I and Algebra II subjects. However, only 62 percent of the overall population of high school graduates in 2000 finished three years of math in a manner that successfully introduced them to this integral content. This figure implies that students are not gaining the knowledge and proficiency they should possess to perform well in the world outside schooling. In fact, of roughly 70% pupils who promptly advance to college, approximately 28% should enroll in refresher or remedial programs in math or English. Moreover, a significant number of fourth grade and eight grade students poorly performed in the National Assessment of Educational Progress (NAEP) in 2003. (DiMaggio, 2001, p. 5). Every state that participated in the NAEP 4th grade math assessment test in 2000 and 2003 reported improvements in mean scores. Among the states that participated in the NAEP 8th grade assessment test in 2000 and 2003, the mean scores improved in numerous states (DiMaggio, 2001, p. 5). In a nutshell, the mean scores at all grade levels improved. Such progress is inspirin g and rewarding but the scores still show the unsatisfactory outcome of collaborative attempts to greatly improve the performance of all students. To sum up, the performance of students in math is not where they should be when measured up to the nation’s standards, the achievement levels of their international counterparts and their capacity to function well beyond high school (Strebe, 2009). The nation needs individuals that is capable of performing in the contemporary world, which implies that new teaching and learning strategies are needed to achieve the desired outcomes in math and other major subjects. Cooperative Learning Groups Learning has traditionally been focused on ‘competition’, hence, the emergence of cooperative learning. Cooperative learning is a model of instruction where small groups composed of learners of distinct capability levels team up to achieve common objectives and take full advantage of their potentials. Cooperative learning facilitate s individual responsibility within the framework of cooperation or group dynamics (Williams, 2002). Teamwork is an important component of the attainment of learning objectives of the course. In the context of cooperative learning, the learning is planned and organized to ensure that learning is actually occurring (Kagan, 1994). The teacher picks the groups to think about a multitude of perspectives, capabilities, ethnic/racial affiliations, gender and other attributes. Furthermore, cooperative learning builds a classroom partnership and harmonizes individual responsibility and interdependence. Because the task of the group is incomplete until every member has accurately and clearly understood the topic, every student is contributing to the attainment of a shared objective. With every student accountable to a specific part of the
