=3.8 Spreadsheets, Modeling, and Simulations =

Introduction: The increasing capabilities of computers have allowed individuals and organizations to develop software that can be used to test “what-if” scenarios and create simulations and models of real-world events.

Spreadsheets, through the use of worksheets and graphs, can be used to manage, predict using a series of “what-if” scenarios, and display financial details of businesses.

Modeling and simulations can be used to recreate or predict the conditions that may result from an event, for example, the areas that will be affected by coastal flooding as a result of different levels of global warming.

It is important that the ITGS student is aware of the benefits of creating accurate spreadsheets, models and simulations as well as the social impacts that could result from simulations being unable to replicate the real world, and the ethical issues that may arise during the development of the model.

Possible scenarios: Students are expected to carry out practical activities using spreadsheets, for example, the development of a spreadsheet that allows a teacher to add marks from a class test so as to generate information such as the grade for the test.

Students are expected to use modeling and simulations to reinforce their theoretical knowledge, and to apply the ITGS triangle to a range of real-life scenarios.

IT concepts to address in this topic: Theoretical and practical concepts for spreadsheets • Cell types: for example, text, number, date, currency, hyperlinks • Formulas: relative and absolute cell references • Sorting, filtering and replicating data • Types of charts • Formatting and presentation: for example, text (fonts), background, paragraphs, pagesSyllabus content • Data validation, verification and testing • Functions: maths, text, logic, date • Protection for sheets and workbooks, cell locking • Advanced functions: for example, lookup, pivot tables, macros • Worksheet modeling: “what-if” analysis (scenarios, goal seek tool)

Modelling and simulation technologies and considerations • Model • Simulation • Types of simulations and models • Virtual reality, augmented reality, gaming: for example, MMORPG (massively multiplayer online roleplaying game) • Graphics and animations (2D, 3D) • Visualization of data • Feedback loop

Developing and using models and simulations • The validity of the model and verification of the results of a simulation, reproducibility of results • Relationship of model to reality • Relationship between a model and a simulation

[8 marks] 3 three questions whose answers you would need for a life cycle analysis model comparing the environmental impact of juice boxes with the environmental impact of juice in bottles. (Use the questions for diapers in Figure 7.2 as a guide.) Consider manufacture, transportation, use, and disposal. [3 marks} 4 Suppose a computer program uses the following data to determine in how many years an important natural resource (say, copper) will run out. IDENTIFY all the reasons you can think of why this program is not a good predictor of when we will run out of the resource. [4 marks] 5 In 1972, a group called the Club of Rome published a study using computer models that implied that the world would run out of several important natural resources in the 1980s. Today, even with the enormously increased demand from China and other developing countries, we have not run out. EXPLAIN why you think many people accepted the predictions in the study? [6 marks] 6 Recent predictions for population growth in the 21st century have changed quite a bit from predictions made a few decades ago.
