Finally, efficiency is the fourth area of the evaluation. Efficiency is an important area to consider because it allows students the optimum level of education and understanding without either oversimplifying to the level that they lose interest, or overburdening so that students feel there is too much material to cover. Efficiency measures how much necessary and unnecessary information is included within the lesson, and quality materials contain very little unnecessary information. Another aspect of efficiency is whether or not a sufficient number of examples and practice problems were included within the lesson itself. Finally, efficiency implies that the lessons provided within the material will actually help them in understanding the material.
B) the objective for Math 8th grade level that I will pursue is understanding of polygons within geometry and how they function.
C)
http://www.scienceu.com/geometry/classroom/buildicosa/index.html would not ultimately use this as part of my lesson plan because of several reasons. While the procedures of this project is very unique in that it allows students to interact with the project, it does a poor job of conveying the actual objective of the course material. Since building such a polygon requires a significant amount of time, rather than being a tool to facilitate learning, the building and hands on nature of this project actually becomes the bulk of...
Thus students have a great time during the construction but do not gain an understanding of the course material. Thus this is an inefficient use of class time and does not meet the design and efficiency standards of the evaluation. http://www.scienceu.com/geometry/articles/tiling/index.html
This following exercise also focuses on the importance of geometric design and formulation of shapes. However, it lacks a specific focus and attempts to teach too much in a given timeperiod. There are many different things to analyze when concerning tiles within geometry therefore this lesson plan is a little too complicated. However, it does allow students to interact with its model and develop an interest in learning more about the geometric problems presented in this analysis. Overall I would recommend this project. http://www.scienceu.com/geometry/activities/tetrapuzzles/index.html
This exercise is the best of the three reviewed because it meets almost all of the criteria of the material evaluation. Not only does it present a simple and clear concept, how a cube is made and the geometric properties of this polygon, but more importantly it does not take a significant amount of time. It emphasizes the point but does not belabor it and thus allows students to understand and interact without making the exercise redundant and too complicated. This will arouse interest, but clearly emphasize the lesson plan.
