Digital Microscope last appearance in the field of microscopy. This device comes in very handy when the teacher wants to asses the performance of students. Image capture has become a simple and fast compared with other traditional methods, such as practical experiments. Performance standards are usually planned in the education system. Sometimes it becomes difficult to justify, and execute them well. Using a digital microscope allows to strengthen existing standards of the school.

Digital microscopes, such as SmartScope provide one of the most effective methods for assessing students’ ability to observe, learn and record various aspects of the sample, whether biology, earth sciences, chemistry and ecology. As Dr. Martin G. Horejsi offers “Instead of the usual drawing lab notebook, students can capture many images reliably outlining their journey in microcosm.” (Horejsi, M. (2007). The value of the painting words: Digital image as a powerful tool for assessing the work of ED-Media Conference of the World Conference on Educational Multimedia, Hypermedia and Telecommunications, Vancouver, Canada).

The digital microscope can be used to capture images, then have a much better way of presenting the data collected in comparison with conventional drawing, which may not be very accurate. The digital microscope can be connected using USB ports, and images obtained at the time by simply clicking the mouse button. The device is simple to operate and can be easily handled, even young students. Changes in the sample under observation can be accurately noted, taking the form at the right time. This is a great way to document the static samples.

Images can be presented using PowerPoint. Images can be zoomed to take a closer look at the different parts of the sample, useful in the accurate and detailed study. Students can also submit images to show a special process under observation. For example, images in the chemical process, for example, confirmatory tests can be captured at different stages, where the color and condition of the substance, it is easy at the right time and is depicted in a series of images slideshow.

In the case of research related to record the behavior of the sample during the period of time, digital microscope provides the possibility of video and time video. For example, seed germination process under investigation can be easily recorded in SmartScope. Videos can be taken within a few hours, where the result can be seen in one minute. This can be done to limit 180:1, ie video, shot during the 180 minutes you can see in a minute. The changes can even be measured by measuring the feature of a digital microscope.

After students have collected the necessary data, using images, video, slide show or PowerPoint completed sheet, it can be easily archived on CD-ROM, thumb drive, e-mail or posted online for others to see. This collection can be assembled as a portfolio, to test and evaluate students’ progress. The use of digital microscopes, such as SmartScope makes it easy for teachers and schools to determine exactly how it takes less time and requires much less effort. This time can be used with students to help them better understand the concept.
