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.
