Examination
Let me deal first with the positive side of examination. First, exams are a proper incentive for students to study and review course materials. A lot of students in the college do not study until they have an exam. Another point is that exams are fair assessment because, the same test is used for all students, it also decrease the opportunity to cheat or make someone else do students work. A final point is that exams help students to know what they understand and don’t understand of the course content because, they don’t know the content of the exam so they should study material.
The arguments against exams are well known. Exams make students nervous about taking exams which make them have bad grades. It is also an unfair way to assess knowledge; using home work is better. Exams are not a good way for a complete evaluation of a student’s skills and abilities because a student might be sick on the day of the exam.
In conclusion, I think that having small exams help students to concentrate at the course content but, home work and projects are a better way to grade student with, because of stress on exams and sickness problems. This also makes the students show more respect to the teachers.
U.S number of farms
In the period between 1910 - 1930 the trends shows a slightly decline in the number of workers and a slight rise in the numbers of farms. Five years later a slightly rise occurred. Between 1935 - 1950 the workers number fall sharply. in the last of the period they stayed the same while, farms fall slightly. Worker numbers fall sharply with the number of farms in the past 25 years. In the last quarter of the century worker numbers slightly fell then fluctuated where as the numbers of farms increased in the end.
In conclusion the number of farms and workers in this graph showed sharp fall in numbers from the first to the end of the century.
Immigration to the UK
This graph shows the immigration to the UK by the date of entry, people numbers on thousands. For the West Indies, India & Pakistan. For the period between 1940 to 1980.
The graph shows a slight increase in the number of people between 1940 to 1950. Between 1950 and 1955 West Indies immigrates roughly increases to less than 20 thousand whereas; India and Pakistan immigration shows a slight increase to nearly 10 thousand in that period of time. From 1960 to 1965 West Indies peak at more than then drop 35 thousand to less than 10 thousand five years later. On the other hand and in the same period India and Pakistan immigrates roughly increases to over 25 thousand then slightly decreases by 5 thousand. Between 1970 to 1980, West Indies slightly increases then roughly decreases to 5 thousand whereas; India and Pakistan went nearly the peak of 35 thousand then roughly shows a decrease of 5 thousand.
