Personalized System of Instruction



Personalized System of Instruction

The Personalized System of Instruction fits into several paradigms, but is most closely aligned with direct instruction. It fits with direct instruction by requiring student to work on course modules independently. It fits slightly with social constructivism by also requiring students to meet weekly in peer teams with a proctor to answer questions and take a quiz on the content studied. Students do not engage in considerable team work as most social constructivist models advocate, rather, they only correct one another's responses to proctor-led questions.

Design and Development Tips
Since PSI units are self-paced and typically designed for students in large lecture classes, technologies that can be accessed by many students in any location are preferable. For instance, web pages or CD-Rom modules in computer labs allow for multimedia modules to be easily accessed. To compile multimedia elements, it may also be necessary to work with audio editing software, video editing software, and image editing software.


Caller's Personalized System of Instruction

In 1960s, Keller built a personal system of instruction seeking to promote mastery of a predetermined set of objects for each learner. Burton, Moore and Magliaro (1996) described PSI (Personalized System of Instruction) as an interlocking system of instruction, which consists of sequentially, progressive tasks. The major components in the system include pre-specified objectives and self-paced modules.
In Keller's (1968) paper, he identified five essential features of a personalized course:
  1. It "permits a student to move through the course at a speed commensurate with his ability and other demands upon his time": a self-pacing feature.
  2. It "lets the student go ahead to new material only after demonstrating mastery of that which preceded": progressively sequential units
  3. Lectures and demonstrations are no longer "sources of critical information. Instead, they are vehicles of motivation.
  4. Teacher-student communication is mainly conveyed via written word.
  5. Use of proctors, "which permits repeated testing, immediate scoring, almost unavoidable tutoring, and a marked enhancement of the personal-social aspect of the educational process"
Based on the description of personalized system of instruction by Educational Technologies at Virginia Tech, listed the steps for developing the personalized system of instruction as follows:
  1. Identify goal statements
  2. Break content into chunks
  3. Develop study guides, including objectives, study procedures, questions, individual works
  4. Student self pace each unit
  5. Test and provide immediate feedback
  6. Review and retest
  7. Present more new units
Research on PSI has proved that PSI can be extremely effective in producing significant improvement in students achievement (Burton, Moore and Maliaro, 1996). More resources about PSI can be found on the PSI homepage developed by Robert Allan and Howard Gullup.

Six Characteristics of the PSI Approach
 1.  Individually paced
2.  Content mastery (criterion learning)
3.  Student tutors
4.  Use of study guides (behavioral objectives
5.  Minimal use of lectures
6.  Division of course content into chunks.
