Societies of Educational Technology


Societies concerned with educational technology include:

Report about Educational Benefits of Frequent Technology Use


Teachers who use technology frequently in their classrooms perceive greater benefits to student learning--particularly learning 21st century skills--than teachers who are less frequent users. That's one of the major findings from a K-12 technology study released Monday by researchers out of the Richard W. Riley College of Education and Leadership at Minnesota's Walden University.
The report, titled "Educators, Technology and 21st Century Skills: Dispelling Five Myths," was based on a survey of more than 1,000 K-12 educators and school administrators in the United States, specifically 783 teachers and 274 principals or assistant principals. It was designed to gauge the use of technology in the classroom and perceptions of technology in education. Researchers released the report at the ISTE 2010 convention happening this week in Denver.
What it found was a great disparity between teachers in terms of their uses of technology, although, contrary to expectations, the frequency of technology use wasn't predicted by teacher experience. New and experienced teachers were about as likely to be "frequent" users of technology in the classroom as they were to be "moderate," "sporadic," or "infrequent" users.
Use and Perceptions of Technology
About 22 percent of those surveyed were considered frequent users of technology, spending 31 percent or more of class time using technology to support learning. Seventeen percent were defined as moderate users, those who spend 21 percent to 30 percent of class time using technology; 26 percent sporadic users, spending 11 percent to 20 percent of class time using technology; and 34 percent infrequent users, who reported spending 10 percent or less of class time supporting learning with technology.
Secondary teachers tended to be more heavy users than elementary teachers. Teachers of certain subjects were also more frequent users on the whole, especially science and social studies teachers, 33 percent of whom reported being frequent users, and math teachers, 31 percent of whom reported frequent classroom technology use.
Those who reported being frequent users cited distinct benefits to student learning as a result of technology use.
According to the report's authors, "Frequent technology users place considerably more emphasis on developing students' 21st century skills--specifically, skills in accountability, collaboration, communication, creativity, critical thinking, ethics, global awareness, innovation, leadership, problem solving, productivity and self-direction. Frequent users also have more positive perceptions about technology's effects on student learning of these skills--and on student behaviors associated with these skills."
On the whole, teachers and administrators reported benefits of technology use for all types of students, from high achievers to students with behavioral and emotional issues.
Preparation and Support
But teachers also reported unsatisfactory levels of support and preparation for the use of technology in the classroom.
"In reality, teachers who have completed their initial certification or licensure since 2000 do not believe that their pre-service programs taught them how to teach 21st century skills or how to effectively incorporate technology into instruction,..." according to the report.
Of those who completed their initial certification or licensure since 2000, more than half reported that their initial teacher preparation programs failed them in these respects. But of those who completed advanced training and certification since 2000, 60 percent or more thought their advanced programs prepared them for teaching 21st century skills and incorporating technology into instruction.

Theories and practices


Three main theoretical schools or philosophical frameworks have been present in the educational technology literature. These are Behaviorism, Cognitivism and Constructivism. Each of these schools of thought are still present in today's literature but have evolved as the Psychology literature has evolved.

Behaviorism

This theoretical framework was developed in the early 20th century with the animal learning experiments of Ivan Pavlov, Edward Thorndike, Edward C. Tolman, Clark L. Hull, B.F. Skinner and many others. Many psychologists used these theories to describe and experiment that is parallel to human learning. While still very useful this philosophy of learning has lost favor with many educators.

Skinner's contributions

B.F. Skinner wrote extensively on improvements of teaching based on his functional analysis of Verbal Behavior[8] and wrote "The Technology of Teaching",[9] an attempt to dispel the myths underlying contemporary education as well as promote his system he called programmed instruction. Ogden Lindsley also developed the Celeration learning system similarly based on behavior analysis but quite different from Keller's and Skinner's models.

Cognitivism

Cognitive science has changed on how educators view learning. Since the very early beginning of the Cognitive Revolution of the 1960s and 1970s, learning theory has undergone a great deal of change. Much of the empirical framework of Behaviorism was retained even though a new paradigm had begun. Cognitive theories look beyond behavior to explain brain-based learning. Cognitivists consider how human memory works to promote learning.
After memory theories like the Atkinson-Shiffrin memory model and Baddeley's Working memory model were established as a theoretical framework in Cognitive Psychology, new cognitive frameworks of learning began to emerge during the 1970s, 1980s, and 1990s. It is important to note that Computer Science and Information Technology have had a major influence on Cognitive Science theory. The Cognitive concepts of working memory (formerly known as short term memory) and long term memory have been facilitated by research and technology from the field of Computer Science. Another major influence on the field of Cognitive Science is Noam Chomsky. Today researchers are concentrating on topics like Cognitive load and Information Processing Theory. In addition, psychology as applied to media is easily measured in studying behavior. The area of media psychology is both cognative and affective and is central to understanding educational technology.

Constructivism

Constructivism is a learning theory or educational philosophy that many educators began to consider in the 1990s. One of the primary tenets of this philosophy is that learners construct their own meaning from new information, as they interact with reality or others with different perspectives.
Constructivist learning environments require students to use their prior knowledge and experiences to formulate new, related, and/or adaptive concepts in learning. Under this framework the role of the teacher becomes that of a facilitator, providing guidance so that learners can construct their own knowledge. Constructivist educators must make sure that the prior learning experiences are appropriate and related to the concepts being taught. Jonassen (1997) suggests "well-structured" learning environments are useful for novice learners and that "ill-structured" environments are only useful for more advanced learners. Educators utilizing technology when teaching with a constructivist perspective should choose technologies that reinforce prior learning perhaps in a problem-solving environment.

Instructional technique and technologies

“Children and young people are growing up in a vastly changing context. No aspect of their lives is untouched by the digital era which is transforming how they live, relate and learn”[10] Some examples of these changes in the classroom include Problem Based Learning, Project-based Learning, and Inquiry-based learning. Together they are active learning educational technologies used to facilitate learning. Technology which includes physical and process applied science can be incorporated into project, problem, inquiry-based learning as they all have a similar educational philosophy. All three are student centered, ideally involving real-world scenarios in which students are actively engaged in critical thinking activities. The process that students are encouraged to employ (as long as it is based on empirical research) is considered to be a technology. Classic examples of technologies used by teachers and Educational Technologists include Bloom's Taxonomy and Instructional Design.[11]

Technology in the classroom


There are various types of technologies currently used in traditional classrooms. Among these are:
  • Computer in the classroom: Having a computer in the classroom is an asset to any teacher. With a computer in the classroom, teachers are able to demonstrate a new lesson, present new material, illustrate how to use new programs, and show new websites.
  • Class website: An easy way to display your student's work is to create a web page designed for your class. Once a web page is designed, teachers can post homework assignments, student work, famous quotes, trivia games, and so much more. In today's society, children know how to use the computer and navigate their way through a website, so why not give them one where they can be a published author. Just be careful as most districts maintain strong policies to manage official websites for a school or classroom. Also, most school districts provide teacher webpages that can easily be viewed through the school district's website.
  • Class blogs and wikis: There are a variety of Web 2.0 tools that are currently being implemented in the classroom. Blogs allow for students to maintain a running dialogue, such as a journal,thoughts, ideas, and assignments that also provide for student comment and reflection. Wikis are more group focused to allow multiple members of the group to edit a single document and create a truly collaborative and carefully edited finished product.
Blogs allow the student to express their knowledge of the information learned in a way that they like. Blogging is something that students do for fun sometimes, so when they are assigned an assignment to do a blog they are eager to do it! If you are a teacher and need to find a way to get your students eager to learn, create, and inspire assign them a blog. They will love it.
  • Wireless classroom microphones: Noisy classrooms are a daily occurrence, and with the help of microphones, students are able to hear their teachers more clearly. Children learn better when they hear the teacher clearly. The benefit for teachers is that they no longer lose their voices at the end of the day.
  • Mobile devices: Mobile devices such as clickers or smartphone can be used to enhance the experience in the classroom by providing the possibility for professors to get feedback.[42] See also MLearning.
  • Interactive Whiteboards: An interactive whiteboard that provides touch control of computer applications. These enhance the experience in the classroom by showing anything that can be on a computer screen. This not only aids in visual learning, but it is interactive so the students can draw, write, or manipulate images on the interactive whiteboard.
  • Digital video-on-demand: Replacement of hard copy videos (DVD, VHS) with digital video accessed from a central server (e.g. SAFARI Montage). Digital video eliminates the need for in-classroom hardware (players) and allows teachers and students to access video clips immediately by not utilizing the public Internet.
  • Online media: Streamed video websites can be used to enhance a classroom lesson (e.g. United Streaming, Teacher Tube, etc.)
  • Online study tools: Tools that motivate studying by making studying more fun or individualized for the student (e.g. Study Cocoa)
  • Digital Games: The field of educational games and serious games has been growing significantly over the last few years. The digital games are being provided as tools for the classroom and have a lot of positive feedback including higher motivation for students.[43]
There are many other tools being used depending on the local school board and funds available. These may include: digital cameras, video cameras, interactive whiteboard tools, document cameras, or LCD projectors.
  • Podcasts: Podcasting is a relatively new invention that allows anybody to publish files to the Internet where individuals can subscribe and receive new files from people by a subscription. The primary benefit of podcasting for educators is quite simple. It enables teachers to reach students through a medium that is both "cool" and a part of their daily lives. For a technology that only requires a computer, microphone and internet connection, podcasting has the capacity of advancing a student’s education beyond the classroom. When students listen to the podcasts of other students as well as their own, they can quickly demonstrate their capacities to identify and define "quality." This can be a great tool for learning and developing literacy inside and outside the classroom. Podcasting can help sharpen students’ vocabulary, writing, editing, public speaking, and presentation skills. Students will also learn skills that will be valuable in the working world, such as communication, time management, and problem-solving.
Although podcasts are a new phenomenon in classrooms, especially on college campuses, studies have shown the differences in effectiveness between a live lecture versus podcast are minor in terms of the education of the student
