Frequently Asked Questions
The Georgia Department of Education maintains an approved calculator list that typically includes models from Texas Instruments (TI-84 Plus series, TI-Nspire CX without CAS), Casio (FX-9750GII, FX-9860GII), and other manufacturers. The specific approved models may vary by assessment and year, so educators should consult the most recent guidance from the Georgia Department of Education. Generally, calculators with computer algebra systems (CAS), QWERTY keyboards, or internet connectivity are not permitted on state assessments.
Research indicates that when used appropriately, graphing calculators enhance rather than diminish mathematical understanding. They allow students to explore multiple representations of mathematical concepts, investigate patterns, and solve complex problems that would be impractical manually. The key is balanced implementation—using calculators for appropriate tasks while ensuring students develop fundamental skills and conceptual understanding. Graphing calculators are particularly effective for visualizing abstract concepts, testing conjectures, and focusing cognitive resources on mathematical reasoning rather than computational mechanics.
Yes, students need to develop both technical proficiency and strategic thinking skills for effective calculator use. Technical skills include efficient navigation, proper syntax for mathematical expressions, and familiarity with key functions like graphing, tables, and statistical analysis. Strategic skills involve knowing when to use the calculator, selecting appropriate functions for different problem types, and interpreting calculator output correctly. Students also need practice with testing-specific protocols, such as memory clearing and time management. Effective instruction develops these skills progressively throughout the school year rather than just before assessments.
Schools can address equity concerns through several approaches: maintaining classroom sets of calculators for in-school use, implementing loaner programs for home use, seeking funding through grants or community partnerships for calculator purchases, and utilizing free emulator software for practice when physical calculators aren’t available. During assessment, schools must ensure all students have access to approved calculators. The Georgia Testing Graphing Calculator’s standardized interface helps mitigate advantages that might come from familiarity with more advanced personal calculators. Ultimately, consistent access and instruction throughout the learning process is more important than owning a personal device.
The primary difference is that approved graphing calculators for Georgia testing do not include Computer Algebra System (CAS) functionality. CAS calculators can perform symbolic manipulation—they can simplify expressions, solve equations symbolically, and compute derivatives and integrals in exact form. Standard graphing calculators primarily work numerically—they compute approximate solutions, graph functions, and perform statistical calculations. CAS calculators are generally not permitted on Georgia assessments because they can perform algebraic steps that students are expected to demonstrate manually. This distinction ensures that assessments measure students’ mathematical reasoning rather than their ability to use advanced technology.
Introducing graphing calculators effectively requires a structured, progressive approach. Begin with basic operations and navigation, using simple arithmetic to build comfort with the interface. Then introduce graphing with linear functions, focusing on window settings and trace features. Progress to more complex functions and applications as students gain proficiency. Use guided activities with specific step-by-step instructions initially, then transition to more open-ended exploration. Always connect calculator use to mathematical concepts—for example, after students have learned to solve quadratic equations manually, show how graphing provides visual confirmation of solutions. Consistent, integrated practice throughout the curriculum is more effective than isolated “calculator lessons.”
Multiple resources support effective graphing calculator instruction: The Georgia Department of Education provides assessment guides with calculator information; calculator manufacturers offer extensive online tutorials and activity resources; professional organizations like NCTM (National Council of Teachers of Mathematics) publish articles and lesson plans incorporating graphing technology; many textbooks include calculator activities aligned with content; online teacher communities share successful instructional strategies; and professional development workshops specifically focus on technology integration. Additionally, many schools have instructional technology specialists who can support teachers in effectively implementing graphing calculators in their mathematics instruction.
