Justification for Recommendation - Assignment Example A learning scenario is a prioritized description of a situation in learning, which is independent of any underlying pedagogical approach. The scenario describes an organization with the aim of ensuring the appropriation of prà ©cised set of skills, competence, and knowledge. The learning scenario in this case is a practical learning scenario. A practical learning scenario consists of descriptions followed by respective questions although the scenario could develop in stages with each stage having at least one question (Shepherd, 2011). Information may be presented with the use of various media elements such as texts but the described situation has to be relevant and realistic. In theory, various formats of questions could be employed in order to challenge learners about the situation being learned including the simple multi-choice questions. Any of the various theory formats are meant to determine the abilities of students in their capacity to answer various forms of questions (Leje une A., 2004). In this learning scenario, the learning objectives involve the determination of the ability of students to answer various forms of questions. The objective includes expectations that lie within the outcome of the education program. The paper will establish the capacities that students have in handling questions in different forms as part of their assessment program within a practical learning scenario (Shepherd, 2011 ). The American Psychological Association (2013) provides information on a code prepared by a joint committee for testing practices as a way of ensuring that there is enough observation of fairness among test takers in education. Code of Fair Testing Practices provides guidance in the development and selection of tests. It also provides guidance in the administration and score determination in tests and goes to an extent of ensuring good reporting and interpretation of test results in order to keep the test takers

Lung diffusion capacity testing (DLCO) is a noninvasive test which is used to measure the movement of gases (most specifically oxygen) through the lung into the bloodstream. The single breath diffusing capacity test is the most common way to determine DLCO, whereby the subject is required to blow out as much air as he or she can so that only the residual gas is left in the lungs. Moreover, the subject is requested to take a deep breath in order to completely fill up the lungs. The subject is then requested to hold his or her breath for a very short period of time. The subject is then finally requested to exhale. The analysis of the gas that has been blown out will then be carried out in order to determine how much went into the bloodstream through the lungs (De Boer, 2010). 23 Pulmonary function tests (abbreviated PFT), which are also known as lung functions tests, are tests which are used so as to provide measures of gas exchange, lung volumes, flow rates, and respiratory muscle function. These tests determines the quantity of air that the lungs can hold, how fast air can possibly be moved in and out of the lungs, as well as the lungs’ ability to add oxygen and remove of carbon dioxide into and from the blood respectively. According to Goldman (2005) and De Boer (2010) the pulmonary function tests have the ability to diagnose diseases of the lungs, to measure how sever the lung problems are, and to monitor the treatment of the lung diseases. Since the spirometer was first developed in 1846 by Hutchinson, measurements of the dynamic volumes of the lung as well as of maximal flow rates have been employed to detect and quantify the diseases which affect the airways and lung parenchyma (White, 2004). The lung function may be determined by the use of tests
