Understanding the Keller Plan

The Keller Plan, also known as the Personalized System of Instruction (PSI), is an educational approach developed by Fred S. Keller. Its core principle is to tailor the learning experience to meet the unique needs and abilities of each individual student. This contrasts with traditional, one-size-fits-all teaching methods.

Keller Plan as Personalised System of Instruction

The Keller Plan is fundamentally a Personalised System of Instruction because it emphasizes:

• Individualized Pacing: Students are allowed to progress through the course material at their own pace. They don't have to keep up with the fastest learners or wait for slower ones.
• Modular Content: The course material is broken down into smaller, manageable units or modules. Each module covers a specific topic or skill.
• Mastery Learning: Students must demonstrate a thorough understanding (mastery) of the material in one module before moving on to the next. This ensures a strong foundation.
• Immediate Feedback: Students receive prompt feedback on their work, often through graded assignments or tests, allowing them to correct misunderstandings quickly.
• Student Tutors/Proctors: Often, more advanced students or teaching assistants help provide feedback and guidance.

Given these characteristics, the Keller Plan directly addresses the individual need (by allowing self-pacing and focusing on mastery) and ability (by ensuring students master content before advancing) of the student, making Personalised System of Instruction the most fitting alternative name.

Evaluating Other Options

Let's look at why the other options are not the best fit:

• Project Work: This is a teaching method where students engage in extended, often complex tasks to explore a topic. While it can be personalized, it's not synonymous with the Keller Plan's structure.
• Computer-assisted Instruction (CAI): This involves using computers to deliver instruction, often through drills or tutorials. While PSI can be *delivered* via computer, CAI itself doesn't necessarily imply the personalized pacing and mastery features central to the Keller Plan.
• Computer-managed Instruction (CMI): This uses computers to manage the learning process (e.g., tracking student progress, assigning tasks), but the instruction itself might still be traditional. CMI focuses on the administration side, whereas PSI focuses on the student's learning experience.

Therefore, the Keller Plan's focus on individual pacing, mastery, and adaptation to student capabilities makes it synonymous with a Personalised System of Instruction.
