Integrating Technology into Mathematics Education Using Impact Diagrams and Decision Trees

Abstract

The aim of this paper is to answer the following questions: What is meant by models of decision analysis, philosophy, and components? What is the role of decision models in analyzing the decision problem to reach the expected value? What is the logical relationship between the two models of decision analysis: the influence diagram, the decision tree, in solving the decision problem? In order to answer the research questions, the steps for building an influence diagram and how to draw it, as well as steps for building a decision tree and how to draw it, were presented. This research also clarified how to turn the tree back and reach the best option using the expected financial value base, and the importance of the role of sensitivity analysis in choosing assumptions and structured alternatives in decision analysis as one of the many advantages of using typical decision analysis in decision-making and decision-making. Based on decision analysis and the use of the two models, the best option is to have a math lab with an expert and pay eight thousand dollars, and to achieve material value (conceptual structures, facts and skills) and moral value (appreciation and respect). And use the evaluation process by conducting achievement tests.  Refer to studies and research that address controversial issues of the use of the Mathematics and Computer Laboratory in education.
