Schools are set up in many different ways. There are differences in dress codes, grading systems, and scheduling. The standard scheduling is having nine periods during one day and lunch is included in those periods. There is also a type of scheduling called black/modular scheduling. This usually has four periods of class for one day. Lunch in this type of system is not included in these periods. Block scheduling should not be implemented in school systems.
             One reason block scheduling should not be used is it can cause academic harm to the students. First, there is the problem of adolescent attention span. Even though classes are twice as long the student may not retain twice as much material. Many teachers know about the short attention span of most teen-agers. The teachers would have to have more "fun" activities to keep the kids interested. This method of lessons will water down the content in the course. Second, the common-sense problem with block scheduling is retention. In most forms of block scheduling students go through one year of classes in one semester. Many months will pass before one class to the next class in sequence. The student will probably forget most of the information that is taught in the time it can take to go from class to the next class. This will make tests like ACT's be much harder because the students have that much time to forget what they learned. Third, less total time is spent on core classes in typical block scheduling programs. One 90-minute class is ten percent less time than two fifty-minute classes. True, this will give the students more time on electives but it will cut down on the time in math, English, and other core classes (Lindsay, Jeff).
             Another reason block scheduling should not be used is the student will not get as much time for the class as expected. One example in some forms of block scheduling students does not attend school as much. In a form, called 4X4, school i...
