In order to create an effective media tool for the classrooms there are several factors to consider. In addition, concentration should be placed in the construction and deliverance of the materials presented rather than the technological aspects. A good model that takes these items into consideration is the Jasper Project.
In chapter five of Michael Moore and Greg Kearsley's Distance Education: A Systems View, the authors describe the steps required for media selection as follows:
One of the most important factors in selecting media tools for educational purposes is that they meet the learners needs as well as providing flexibility. When selecting media and technological tools for the classroom all of items listed above should be taken into consideration.
In 1994 Schwier stated that the potential power of interactive technologies for distance education lies in the "way instruction is constructed and delivered-- not in the technological components." A good example of the construction of technology and media in distance education is the Jasper Experiment developed by the Cognition and Technology Group at Vanderbilt. The developers share a common goal "to use technology to develop improved instructional tools for teachers." The Jasper Series creates an improved learning atmosphere that supports the development of problem-solving skills.
The Jasper Project was designed to enhance thinking skills by teaching powerful concepts not though general thinking skills but rather rich content. The Jasper series illustrates problem-solving skills in a kindergarten through twelfth grade environment. There are a series of twelve adventures on videodisc that can be used in any order. Each adventure is approximately seventeen minutes and focuses on mathematical problem solving. It is similar to detective work. After students view the adventure, they are motivated to brainstorm the predicaments for solving the problem. It is suggested they discuss the pros and cons of each conclusion with the entire class. Next, students aided with a video-based analog role-play "what if" situations to rethink and compare a variety of decisions.
The Jasper Project is unique in its approach to learning because it was designed to "bridge the gap between natural learning environments and social learning environments". It presents a genuine story line that challenges students to problem solve. It can also be used in many subject areas besides mathematics. The laserdisc format also provides immediate access to any part of the story. Another admirable feature is that the role models used in the adventures are from diverse backgrounds so that all children should be able to relate therefore avoiding stereotypical charters. In additions, Jasper is used as a tool for community building. It contains the possibility for parents, school administrators, and business leaders to become involved in what students are learning.
Another product developed in addition to the twelve adventures on videodisc includes software support. This allows students to create their own adventures for their classmates to solve. Furthermore, CD-ROM based products are being tested that allow students to access animation and more visual effects. The Jasper series also includes other types of support for teachers to help implement it in their classroom. The adventures generally come with several teaching tools and tips to enhance the use of the products. The Learning Technology Center at Vanderbilt University has furthermore created a web site where teachers can communicate with each other called Classroom Connections.
The materials help learners construct their knowledge by involving students in the decision-making process. By involving students in the process, it relies that students will be able to use their prior knowledge to develop a conclusion.

It is extremely good in providing the details of the project.
