Teaching social studies concepts using concrete models expressed in APL

Content Provider	ACM Digital Library
Abstract	Concepts routinely used in middle and secondary social studies classes are often too abstract for students to comprehend. To fully understand the concept of nation, for example, students must first visualize and comprehend the notions of territory, boundaries, governments, cultures, history and shared goals and dreams for the future as well as other abstractions that may be subsumed in the word. The problem becomes more complex when the teacher works with social studies concepts that are expressed numerically. When students work with familiar numbers in the tens and hundreds, they often have difficulty conceptualizing such ideas as population density and per capita income, which are expressed in terms or a single unit. When the numbers are in the billions or trillions, they are difficult to visualize and to comprehend. When the large numbers are used in social studies concepts such as gross national product, the problem compounds. Students may also lack skill in using mathematical functions involving these large numbers. Teachers want students to understand rich and powerful ideas and they search for classroom activities to enhance student learning. Instructional techniques which provide students with concrete experiences and which allow for manipulation of the environment help students master such concepts. These strategies help students develop the ability to do abstract and formal thinking. This paper focuses on concepts in global studies and presents some techniques for teaching these abstract ideas using computer models expressed in APL. Students manipulate these models in a variety of ways in class. Students learn to do research, store information and access and use data to comprehend their world more fully.
