  2. Microteaching - Wikipedia

    en.wikipedia.org/wiki/Microteaching

    Watching the video and getting comments from colleagues and students provide teachers with an often intense "under the microscope" view of their teaching. A review of the evidence for micro-teaching, undertaken by John Hattie as part of his Visible Learning project, found it was the 6th most effective method for improving student outcomes.

  3. Foldscope - Wikipedia

    en.wikipedia.org/wiki/Foldscope

    A Foldscope is an optical microscope that can be assembled from simple components, including a sheet of paper and a lens. It was created by Manu Prakash and designed to cost less than one USD to build. It is a part of the "frugal science" movement which aims to make cheap and easy tools available for scientific use in the developing world. [2]

  4. Micrograph - Wikipedia

    en.wikipedia.org/wiki/Micrograph

    This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times. Micrography is the practice or art of using microscopes to make photographs. A photographic micrograph is a photomicrograph, and one taken with an electron microscope is an electron micrograph.

  5. Optical microscope - Wikipedia

    en.wikipedia.org/wiki/Optical_microscope

    The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.

  6. Scanning transmission electron microscopy - Wikipedia

    en.wikipedia.org/wiki/Scanning_transmission...

    A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM). Pronunciation is [stɛm] or [ɛsti:i:ɛm]. As with a conventional transmission electron microscope (CTEM), images are formed by electrons passing through a sufficiently thin specimen. However, unlike CTEM, in STEM the electron beam is focused ...

  7. Bright-field microscopy - Wikipedia

    en.wikipedia.org/wiki/Bright-field_microscopy

    Bright-field microscopy is the simplest of a range of techniques used for illumination of samples in light microscopes, and its simplicity makes it a popular technique. The typical appearance of a bright-field microscopy image is a dark sample on a bright background, hence the name.
