What are the lesson learned from new generations school NGS ?

Cambodia new generations school reform

Mrs. Nelson is a 5th grade teacher at Xander Elementary School. Mrs. Nelson is very tech-savvy and uses many forms of social media to communicate with her parents and students. At the beginning of the year, she asks parents to follow her on a communication app, Remind, so that they can receive important text reminders about upcoming events. Remind is typically used for group communication, for example, Mrs. Nelson might send out a reminder to the class that they have a field trip and will need to remember their lunches. After receiving a group text, parents then have the option to respond individually to Mrs. Nelson and they can then carry on a conversation in a private environment if they need to discuss more student-specific information. Many of her students have their own cell-phones and have also begun following Mrs. Nelson the Remind app, and while does not encourage this, she doesn’t remove them when they do. It has never been an issue in the past, and she assumes it might help them to know what is going with upcoming and important events too. Mrs. Nelson is a very loved and respected teacher, and she is known for providing a very safe and nurturing environment in her classroom. Whenever a student is struggling with anything, they always know that Mrs. Nelson will listen and support them. Because of the precarious nature of 5th grade, students often come to Mrs. Nelson with all kinds of problems. After sending out a Remind text about the upcoming early dismissal day, a student, Maddie, responded with a private message to Mrs. Nelson telling her that she needed to talk to her about a problem. Mrs. Nelson tells her to come to her first thing in the morning, so they can talk before class begins. The next morning, Maddie shows up early to class as instructed, and tells Mrs. Nelson that she thinks something is wrong with her because she doesn’t like boys the way her friends do, and but she really doesn’t want to be gay. She is afraid of what her parents and friends would say if she never likes boys the way she thinks she is supposed to. Though she was a little taken aback by this confession, Mrs. Nelson assures her that she will be ok, and that it is ok that she doesn’t have the answers to those questions right now. Thinking about it later that evening, Mrs. Nelson, was concerned that she hadn’t been supportive enough in talking with Maddie, so she sends her a private Remind text saying, “I want you to know that you are a very smart and beautiful young lady, and if you like boys or girls, that won’t change. I won’t say anything to anyone about our conversation.”

Questions:

1. Identify the behaviors (if any) that you believe violate standards in the Educator Code of Ethics?

2. Which standards do you think were violated, explain your reasoning. If you feel that no standards were violated, explain your reasoning?

3. Should Mrs. Nelson have handled this situation differently so as not to violate the Code of Ethics, or (if you feel that there was no violation) to avoid her actions being called into question?

Let S be the educational attainment of individuals in a town, with values S=0 for less than high school and S=1 for high school or above. Also, let Y be their individual annual income with values Y=0 for less than $20,000, Y=1 for between $20,000 and $40,000, and Y=2 for above $40,000. Consider now the following joint probabilities:

S\Y         Y=0 (less than $20K)       Y=1 ($20K-$40K)              Y=2 (more than $40K)

S=0 (Less than HS)            0.05        0.03        0.01

S=1 (HS or more)              0.22        0.36        0.33

Determine the expected value (mean) of the conditional expected level of educational attainment (given the various levels of individual annual income).

A random sample of 862 births included 434 boys. Use a 0.10 significance level to test the claim that 50.7​%

of newborn babies are boys. Do the results support the belief that 50.7​%

of newborn babies are​ boys? Identify the test statistic for this hypothesis test. Identify the​ P-value for this hypothesis test. Identify the conclusion for this hypothesis test.

A school is overcrowded and there are three options. The do-nothing alternative corresponds to continuing to use modular classrooms. The school can be expanded, or a new school can be built to “split the load” between the schools. User benefits come from improvements in school performance for the expanded or new schools. If a new school is built, there are more benefits because more students will be able to walk to school, the average distance for those who ride the school buses will be shorter, and the schools will be smaller and more “student friendly.” The disbenefits for the expanded school are due to the impact of the construction process during the school year. The interest rate is 8%, and the life of each alternative is 20 years. Which alternative should be chosen? What is the incremental ratio for the preferred alternative?

(a) Use the benefit-cost ratio.

(b)Use the modified benefit-cost ratio.

(c)Use the public/government version of the B/C ratio.

Girls of a certain age in the nation have a mean weight of 85 with a standard deviation of 10.8 lb. A complaint is made that girls are underfed fed in a municipal children's home. As evidence, a sample of 25 girls of the given age is taken from the children's home with a mean weight of 89.41 lb. What can be concluded with α = 0.01?

a) What is the appropriate test statistic? (choose one of the following)

1. na 2. z-test 3. one-sample test 4. independent-samples t-test 5. related-samples t-test

b2)
Sample: (choose one of the following)

1. weight 2. children's home 3. girls in the nation 4. feeding method 5. girls from the children's home

c) Obtain/compute the appropriate values to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)

c. The weight of girls in the children's home was not significantly different than the weight of girls in the nation.

Using C++ Create a program that asks the user to input a string value and then outputs the string in the Pig Latin form.

- If the string begins with a vowel, add the string "-way" at the end of the string. For “eye”, it will be “eye-way”.

- If the string does not begin with a vowel, first add "-" at the end of the string. Then rotate the string one character at a time; that is, move the first character of the string to the end of the string until the first character of the string becomes a vowel. Then add the string "ay" at the end. For example, the Pig Latin form of the string "There" is "ere-Thay".

- Strings such as "by" contain no vowels. In cases like this, the letter y can be considered a vowel. So, for this program, the vowels are a, e, i, o, u, y, A, E, I, O, U, and Y. Therefore, the Pig Latin form of "by" is "y-bay".

- Strings such as "1234" contain no vowels. The pig Latin form of the string "1234" is "1234-way". That is, the pig Latin form of a string that has no vowels in it is the string followed by the string "-way". The program should store each character of a string into a linked list and use the rotate function, which removes the first item and puts it at the end of the linked list. The linked list should be implemented as a generic type.

The mayor of a town believes that 78% of the residents favor annexation of a new bridge. Is there sufficient evidence at the 0.02 level to dispute the mayor's claim?

) In the mid-1990s, Colgate-Palmolive developed a new toothpaste for the U.S. market, Colgate Total, with an antibacterial ingredient that was already being successfully sold overseas. At that time, the word antibacterial was not allowed for such products by the Food and Drug Administration (FDA). In response, the name “Total” was given to the product in the United States. The one word would convey that the toothpaste is the “total” package of various benefits. Young & Rubicam developed several commercials illustrating Total’s benefits and tested the commercials with focus groups. One commercial touting Total’s long-lasting benefits was particularly successful. The product was launched in the United States in January of 1998 using commercials that were designed from the more successful ideas of the focus group tests. Suppose 32% of all people in the United States saw the Total commercials. Of those who saw the commercials, 40% purchased Total at least once in the first 10 months of its introduction. According to U.S. Census Bureau data, approximately 20% of all Americans were in the 45-64 age category. Suppose 24% of the consumers who purchased Total for the first time during the initial 10-month period were in the 45-64 age category. Within three months of the Total launch, Colgate-Palmolive grabbed the number one market share for toothpaste. Ten months later, 21% of all U.S. households had purchased Total for the first time. The commercials and the new product were considered a success. During the first 10 months of its introduction, 43% of those who initially tried Total purchased it again. a) What percentage of U.S. households purchased Total at least twice in the first 10 months of its release? b) Can you conclude the initial purchase of Total was independent of age? Use a quantitative argument to justify your answer. c) Calculate the probability that a randomly selected U.S. consumer is either in the 45-64 age category or purchased Total during the initial 10-month period. d) What is the probability that a randomly selected person purchased Total in the first 10 months given that the person is in the 45-64 age category? e) What percentage of people who did not see the commercials purchased Total at least once in the first 10 months of its introduction?
