In this assessment (on the next two pages), you will write the first two interactions of a sample Micro-Lesson outline about “Aspect Ratio” in aeronautics. (You will not need to write an entire outline.) This topic was deliberately chosen to be something you are likely unfamiliar with; want to assess your inherent writing ability. Please spend some time to review the guidelines and links to information about the topic given below. You will be assessed on your ability to construct engaging, Socratic interactions based on the guidelines provided.
What’s a Micro-Lesson?
Micro-Lessons are simulated, text-based conversations between the student and an interactive, virtual tutor. View this Example Micro-Lesson. Micro-Lessons are built on four main pillars:
List of Content to be Covered in the Lesson “Aspect Ratio of Airplane Wings”
• Introduce the importance of wing geometry from airplane construction and operation
• Give mathematical definition of Aspect Ratio: AR = s^2/Area = s/mean chord
• Discuss what AR practically means: High AR = long and skinny, Low AR = short and wide
• Explain that AR varies inversely with induced drag, so a higher AR leads to less drag at low to medium speeds → Discuss how this would be helpful for airplanes
• Examine some deficiencies of high-aspect ratio: maneuverability, strength, practicality (storage, useable airfields, use of wing for fuel/wheels/etc.)
Assumed knowledge of student for this concept: Knows 4 force components (weight, drag, lift, thrust), span of a wing, chord of a wing, types of drag
(Assume the student is undergraduate level and this lesson is relatively early in an aeronautics course, though not one of the very first lessons.)
List of Content to be Covered in the Lesson “Benefit-Cost Ratio and its use in Project Selection”
• Definition: BCR compares the expected nominal costs of the project to the potential nominal benefits
• Provide basis for why we would want to compare Benefits and Costs in this way
• Formula: BCR = Benefits/Costs → Get student to recognize this as the formula
• Discuss why you should choose the project with the largest benefit-cost ratio (all else being equal)
a. Give example with same profit but extreme differences in cost and benefit:
A = Cost of $1M and Benefit of $5M
B = Cost of $100M and Benefit of $104M
b. Based only on this information, which project do you think would be better to do?
i. √ A
ii. B → Costs and Benefits during project selection are usually just estimates. Imagine your costs run over by just 5% compared to your estimate. → now this loses money.
iii. They are equally attractive.
c. Indeed. But someone might suggest just comparing the profits of the two projects.
a. [no intro needed]
b. Which project has more profit?
iii. √ Their profits are the same → That’s true.
c. You calculate the profit by subtracting the cost from the benefit. So if you just compared simple profits, you can’t decide between these two. But A is able to produce the same profit with a much smaller investment.
a. [no intro needed]
b. Instead of comparing profits (Benefit minus Cost), how could you use Cost and Benefit to explain that A is preferable to B?
i. √ Divide Benefits by Costs
ii. Multiply Benefits and Costs
iii. Add Benefits and Costs
c. This formula, called the Benefit-Cost Ratio or BCR, is used to compare projects to find the one with the best value for the company without taking time into consideration. The higher the ratio, the better the project, all other things being equal.
a. In the given example, the BCR for Project A is 5 and for B is 1.04. Suppose the expected benefit for Project B decreases so that it is expected to lose money.
b. What would happen to the BCR of Project B?
i. ✓Decrease to a positive number below 1
ii. Decrease to 0
iii. Decrease to a negative number
c. That’s right. Benefit will be less than Cost and they will both be positive, so the BCR will be between 0 and 1. For example, if the new expected benefit for Project B was $95M, then its BCR would be 95/100 = 0.95.
a. You find out that Project A will take 10 years to complete while Project B only takes 6 months.
b. How does this affect the attractiveness of Project A compared to Project B?
i. √ Makes Project A less attractive
ii. Makes Project A more attractive
iii. Doesn’t affect the attractiveness
c. Taking a much longer time makes the project less appealing because it is longer before you realize that profit and can use that money for something else. Also, the value of the profit after 10 years will almost surely be smaller than after only 6 months.
So while BCR is a very simple economic model to apply, it does have many limitations, not only dealing with time, multiple income/cost flows, varying interest rates, etc.
Compelling correspondence is essential to the achievement all things considered but since of the changing idea of the present working environments, successful correspondence turns out to be more troublesome, and because of the numerous impediments that will permit beneficiaries to acknowledge the plan of the sender It is restricted. Misguided judgments.In spite of the fact that correspondence inside the association is rarely completely open, numerous straightforward arrangements can be executed to advance the effect of these hindrances.
Concerning specific contextual analysis, two significant correspondence standards, correspondence channel determination and commotion are self-evident. This course presents the standards of correspondence, the act of general correspondence, and different speculations to all the more likely comprehend the correspondence exchanges experienced in regular daily existence. The standards and practices that you learn in this course give the premise to additionally learning and correspondence.
This course starts with an outline of the correspondence cycle, the method of reasoning and hypothesis. In resulting modules of the course, we will look at explicit use of relational connections in close to home and expert life. These incorporate relational correspondence, bunch correspondence and dynamic, authoritative correspondence in the work environment or relational correspondence. Rule of Business Communication In request to make correspondence viable, it is important to follow a few rules and standards. Seven of them are fundamental and applicable, and these are clear, finished, brief, obliging, right, thought to be, concrete. These standards are frequently called 7C for business correspondence. The subtleties of these correspondence standards are examined underneath: Politeness Principle: When conveying, we should build up a cordial relationship with every individual who sends data to us.
To be inviting and polite is indistinguishable, and politeness requires an insightful and amicable activity against others. Axioms are notable that gracious “pay of graciousness is the main thing to win everything”. Correspondence staff ought to consistently remember this. The accompanying standards may assist with improving courtesy:Preliminary considering correspondence with family All glad families have the mystery of progress. This achievement originates from a strong establishment of closeness and closeness. Indeed, through private correspondence these cozy family connections become all the more intently. Correspondence is the foundation of different affiliations, building solid partners of obedient devotion, improving family way of life, and assisting with accomplishing satisfaction (Gosche, p. 1). In any case, so as to keep up an amicable relationship, a few families experienced tumultuous encounters. Correspondence in the family is an intricate and alluring marvel. Correspondence between families isn’t restricted to single messages between families or verbal correspondence.
It is a unique cycle that oversees force, closeness and limits, cohesiveness and flexibility of route frameworks, and makes pictures, topics, stories, ceremonies, rules, jobs, making implications, making a feeling of family life An intelligent cycle that makes a model. This model has passed ages. Notwithstanding the view as a family and family automatic framework, one of the greatest exploration establishments in between family correspondence centers around a family correspondence model. Family correspondence model (FCP) hypothesis clarifies why families impart in their own specific manner dependent on one another ‘s psychological direction. Early FCP research established in media research is keen on how families handle broad communications data. Family correspondence was perceived as an exceptional scholastic exploration field by the National Communications Association in 1989. Family correspondence researchers were at first impacted by family research, social brain science, and relational hypothesis, before long built up the hypothesis and began research in a family framework zeroed in on a significant job. Until 2001, the primary issue of the Family Communication Research Journal, Family Communication Magazine, was given. Family correspondence is more than the field of correspondence analysts in the family. Examination on family correspondence is normally done by individuals in brain science, humanism, and family research, to give some examples models. However, as the popular family correspondence researcher Leslie Baxter stated, it is the focal point of this intelligent semantic creation measure making the grant of family correspondence special. In the field of in-home correspondence, correspondence is normally not founded on autonomous messages from one sender to one beneficiary, yet dependent on the dynamic interdependency of data shared among families It is conceptualized. The focal point of this methodology is on the shared trait of semantic development inside family frameworks. As such, producing doesn’t happen in vacuum, however it happens in a wide scope of ages and social exchange.
Standards are rules end up being followed when performing work to agree to a given objective. Hierarchical achievement relies significantly upon compelling correspondence. So as to successfully impart, it is important to follow a few standards and rules. Coming up next are rules to guarantee powerful correspondence: clearness: lucidity of data is a significant guideline of correspondence. For beneficiaries to know the message plainly, the messages ought to be sorted out in a basic language. To guarantee that beneficiaries can without much of a stretch comprehend the importance of the message, the sender needs to impart unmistakably and unhesitatingly so the beneficiary can plainly and unquestionably comprehend the data.>
