| CBL (Calculator-based Laboratory) and CBR (Calculator-Based Ranger) are the mobile and portable collecting data equipment. With graphing calculators, the CBR & CBL allow students to easily collect real-time data, view, and analyze the results from the collection of data through the connection of graphing calculators and various sensors such as motion detector, temperature probe, light probe, etc. Hence, this technology allows teachers to use in mathematics and science classrooms to motivate and help students' learning because students can focus on the exploring, understanding, and construction of mathematical and scientific concepts without spending much time on the process of collecting data. The students' learning behaviors will more be like scientists'. For example, Students can explore mathematics and scientific relationships like the distance and time with the motion detector. They can view the data collected form the device on their graphing calculators. This technology also has many calculator programs that can download from Internet. Hence, it is very useful tools to empower teachers' teaching and students' learning. | |
Examples and lesson plans using CBL/CBR in education: The following are the examples of using CBL/CBR in mathematics, physics, and chemistry, etc.
