The main purposes of this research are to construct a junior high level educational website in the field of natural and life science technology and to provide students with an online platform that offers after-school educational and learning assistance. The main contents of the website are laboratory experiment videos. The videos recorded by digital camcorders and edited with multimedia managerial software (Ulead VideoStudio 7.0 SE DVD), capture experimental procedures and results of the laboratory experiments. In addition to the experiment videos, the website also provides students with a variety of supplemental learning tools, including resources to textbook contents, glossary, multimedia tools, problem discussion forum, links to related websites, and an interactive testing center. The main source of material used for this research is Natural and Life Science Technology (junior high level, vol. 4, Nani edition). Students have constant access to the teaching material in the laboratory videos, such as experimental procedures and results; they are thus given an opportunity to consolidate knowledge and memorization of the material through repeated viewing of the videos.The educational website provides students with numerous different types of study tools, which serve to accommodate individual differences in learning style and abilities among every student.
