In a study of 3 years of large scale analysis of the teaching of science, they concluded that children do not get so familiar with the use of abstract ideas and they do better with practice. In an old journal that examined the evolution of the teaching of science in elementary schools, it was apparent that the original approach of teaching science in the 1800s was to get children to perceive nature â€Å"from the childs standpoint† (Curtis, 1950). However, further investigations indicated that as times evolved and institutions of higher learning got structured and teaching methods were institutionalized, middle schools were required to prepare their pupils for advanced courses in science (Curtis, 1950). Thus, although practical studies and practical teaching is important and vital, there is the need for the teaching methods to be relevant to higher education and the real world. The teacher will have to draw a balance between three main things in the teaching of science: Internships for teachers are normally conducted in an academic or school-setting. There is limited exposure to the industry and other institutions of higher learning (Minuskin, 2009). There is an inherent challenge in the funding of these internships. Hence, if it is going to be upgraded to a system that will involve institutions of higher learning, the industry and the development of practical ideas, there will be more cost constraints. This can be reasonably spread through the use of online methods and other developed systems that can be conveniently replicated (Nadarajan, 2011). Also, partnerships between the community and institutions can help to share the costs (Hogue, 2012). The aim of the

Diagnostic Reasoning - Essay Example Even though clinicians can use data from patient’s signs and symptoms to improve previous probabilities, they do not compute a running score of probability ratios. Their evaluation of previous probabilities depends on their understanding of patients and their expertise. They also add proof to a previous chance instead of multiplying proof by a previous probability (Stolper, Van de Wiel, Van Royen, Van Bokhoven, Van der Weijden & Dinant, 2011). In as much as the strength of an analytical indicator to substantiate or reject is mostly evaluated in various terms including irrelevant, weak, and strong, clinicians often use their projected decision threshold before taking actions. Since this has not always provided positive outcome, it is necessary for the medical decision-making clinicians to establish a balance between diagnostic reasoning and a kind of intuitive appraisal. Diagnostic reasoning is applied in complicated cases like testing hypothesis and purposeful verification. Th erefore, general practitioners will have to depend on a kind of intuitive assessment by listing patient features, establishing their weights and matching them with the symptoms related to a particular illness. In conclusion, it is necessary to establish a balance between diagnostic reasoning and a kind of intuitive appraisal. The process allows doctors to come up with a conclusive decision concerning a particular infection. Stolper, E., Van de Wiel, M., Van Royen, P., Van Bokhoven, M., Van der Weijden, T., & Dinant, G. J.
