  1. Teaching and Learning with Technology in Mathematics and Science Instruction Chapter 11

  2. 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

  3. 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.

  4. 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.

  5. 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

  6. 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.
