. Current Technologies Used in Schools
Whatever learning theory a teacher may embrace, many technologies exist in schools to enhance instruction and to support student learning. While teachers vary greatly in their use of these technologies, teachers select media they believe will promote their instructional goals. Following are a few examples of computers being used to support four goals: building student capacity for research, making student inquiry more realistic, enabling students to present information in appealing forms, and offering students access to learning resources within and beyond the school.
Student research. Students once relied upon local and school libraries and their printed reference materials to research topics. Now, however, computer technologies provide access to digital versions of these references–and to libraries worldwide. Encyclopedias on CD-ROMs provide information, digital images, video, and audio, and also provide links to websites where students access tools such as live web cameras and global positioning satellites. Dictionaries and thesauruses are built into word processors. Through the Internet students can gain access to a wide variety of primary and secondary sources, including government documents, photographs, and diaries.
Student inquiry. Educational reformers believe education needs to be real and authentic for students. Technology can engage students in real-world activities. In the sciences, electronic probes allow science students to collect precise weather or chemical reaction data and digitally trace trends and answer hypotheses. Graphing calculators, spreadsheets, and graphing software provide mathematics students with the ability to visualize difficult mathematical concepts. In the social sciences, electronic communication tools (e.g. Internet conferencing, e-mail, electronic discussion groups) allow students to communicate with their peers from many parts of the world. In the language arts, students use handheld computers and wireless networks to create joint writing exercises and read electronic books that allow them to explore related topics. Concept-mapping software provides all students with the opportunity to build the framework for a story or report and to map out linkages among complex characters, such as those in a play by Shakespeare. In the arts, students can explore images of original artwork through the Internet; with appropriate software they can create original digital artwork or musical compositions. Physical education students can use electronic probes to learn about the relationship between the impact of physical movement and physiological changes.
Authentic student inquiry extends beyond data collection. It also implies the opportunity for students to investigate questions or issues that concern them. Communications technology allows students to contact experts such as scientists, book authors, and political leaders. Electronic communication tools support interactions and increase the probability of prompt responses. Students who want to learn more about a current event, such as an experiment on an international space station, scientific endeavors in the Antarctic, an international meeting of environmentalists, or a musher during the Iditarod dogsled race in Alaska, can use the Internet to investigate the topic, participate in a virtual field trip to the event, and watch the event as it unfolds through a web camera. In this manner, instructional technology assists students who wish to investigate their own questions and concerns.
