Activities promoting inquiry skills, including observing, classifying, inferring, predicting, and analyzing, can be first steps toward helping students understand how scientists go about their work. Both of these reform-based documents promote science instruction that emphasizes understanding the ways scientific knowledge is developed, as well as understanding scientific content.įor example, it's one thing to understand the processes of photosynthesis and respiration but an entirely different matter to understand how scientists developed an understanding of these processes.
This capability supports scientific inquiry in the classroom, as described in both Virginia's Standards of Learning and the National Science Education Standards. The accompanying software provides the capability to record both real-time and time-lapse movies, which optical microscopes cannot, and its $99 price tag makes the QX3 affordable in most classrooms. These features make it possible to import the digitized images into other analysis programs, and to incorporate images into word-processed and/or PowerPoint® reports.
But unlike with optical microscopes, the output is displayed on a computer monitor and can also be recorded and saved on a hard disk or diskette. The QX3 has the same capabilities as optical microscopes, including a range of magnifications (10x, 60x, and 200x). One of several technology tools introduced to preservice science is the Intel QX3 digital microscope.
