Teaching and Learning with Technology in Mathematics and Science Instruction

Chapter 11

Issues and Problems in Mathematics

Instructions• Principles and Standards for School Mathematics(2000)- Serves as a primary

resource guide for all who make decisions that affect the mathematics education of students in pre-kindergarten through grade 12

• Helping teachers change their teaching styles to meet the vision described in the National Council of Teachers of Mathematics (NCTM) is not an easy task.

• Teachers should consider an appropriate combination of off- and on-computer activities.

• Teachers should consider technology as a mathematical tool rather than as a pedagogical tool.

• Teachers should also view technology as a tool for developing student thinking.

• Standards can be found at http://www.nctm.org/standards

Technology Integration Strategies for Mathematics Instruction

• Physical manipulatives are real objects such as blocks and coins.

• Virtual Manipulatives are replicas of real manipulatives that are accessed via the Internet and can be manipulated through a keyboard or other input device.

• Our understanding of mathimatical ideas and concepts is closely tied to how we represent the abstractions of mathematics

• Graphing calculators are advanced calculators that can graph equations, as well as perform calculation functions involved in higher-level math and science problems.

• 4 ways to use graphing calculators: Collecting and generating raw data, examining multiple cases, providing immediate feedback and showing graphical and numerical displays.

Technology Integration Strategies for Mathematics Instruction

• Interactive or dynamic geometry software refers to programs that allow users to create and manipulate geometric constructions. Ex: Geometer’s Sketchpad (geometry program)

• Computer algebra system (CAS) are software or devices that help carry out complex numeric calculations involved in higher-level math problems. Ex: Maple (algebra system software).

• Calculator-based laboratories (CBL) provide a means to link either calculators or computers to scientific data-gathering instruments, such as thermometers or pH meters, which allow students to gather data and then analyze it.

• Probeware is made through handheld devices like mobile phones for problem-solving lessons.

• Spreadsheets have long been considered a powerful means of supporting problem-solving exercises.

Issues and Problems in Science Instruction

• The National Science Education Standards, published in 1996, outlines the content that all students should know and be able to do; it also provides guidelines for assessing student learning in science.

• America’s ability to compete in Science is becoming a concern. Leadership is greatly needed for America’s future.

• There is a need for all citizens to be scientifically literate in order to make informed decisions that affect our country’s future.

• Teachers are having difficulty in teaching Science due to the new developments in the content. Needless to say, Science is a rapidly changing area. Advanced Profession Development can help teachers in this problem.

• Hands-on/Minds-on Science is “engaging in in-depth investigations with objects, materials, phenomena, and ideas and drawing meaning and understanding from those experiences

Technology Integration Strategies for Science Instruction

• Authentic science not only involves having students “do” science, it also includes connecting science to students’ lives and life experiences.

• Data loggers are devices that record data over time with sensors, and global positioning systems (GPS), as well as traditional technologies such as a weather shelter and U-tube thermometer.

• The internet has become an indispensable tool for investigating important scientific questions

• Data collection and archiving are important parts of the scientific inquiry process.

• Webcasts are live video broadcasts of an event sent over the Internet.
