Spreadsheets help you to: Gather and enter data. Format data. Work with numbers, formulas, and functions. Use proofing tools. Emphasize your point with charts. According to Jonassen (2000), electronic spreadsheets were originally designed to automate paper-based ledger systems.
“ Spreadsheet” software programs are used to record data and also used as a tool for analyzing data. A worksheet is an Excel document containing rows and columns of information that can be formatted, sorted, analyzed, and charted. Building a worksheet involves entering information, adding formulas, and saving your data. You can even add hyperlinks to your worksheet to access supporting files on your hard disk or on the Internet.
Spreadsheets have three primary functions:
Refer to page 88 – Mills & Roblyer book.
Excel is a productivity tool for storing numbers and computations and a research tool for analyzing, processing, and reporting data. It is useful for problem-solving and decision-making learning activities.
“ Spreadsheets should be used in the classroom because they are a tool that integrates technology into the school environment, provides concrete ways to explore abstract concepts, enhances the class setting for visual learners and younger students, and promotes higher-order thinking skills.” (Lewis 2001, p. 1) Spreadsheets facilitate active, collaborative learning and critical thinking by providing tools that empower students to collect information, look at it in different ways, and share it with others. “ In our increasingly technological world, it is becoming more and more important to integrate technology into the classroom. In addition, it is essential to do this as early as possible. Today’s students have the skills necessary to begin working with technology at an early age. Spreadsheets are one of many ways to introduce younger students to the world of technology. At the same time, spreadsheets also offer challenging opportunities to integrate technology into the schoolwork of older students.” (Lewis 2001, p.2)
There are many formulas that help you calculate or analyze everything from finances to statistical sampling plans. When you combine several steps in a formula, they are performed in a specific order. Excel starts calculating from the left to the right according to the following order of operations: as listed. For examples and meanings of calculation operators in formulas, just click on the Office Assistant and then type Operators . P lease E xcuse M y D ear A unt S ally. Parenthesis – Exponents – Multiplication – Division – Addition - Subtraction
As you can see, spreadsheets are not just part of the math curriculum. They can be used in interdisciplinary units of instruction.
There are tons of resources available on the Internet.
Hold up book and reiterate how all lessons SHOULD correlate with Academic Content Standards and National Technology standards.
