According to the steps proposed by Kurt Lewin and Stephen Corey in the process of action research, when a teacher plans, implements, and modifies their strategy based on the results to solve a specific classroom teaching problem, which of the following is the logical and correct scientific sequence of this entire cycle?

Understanding Action Research Cycle

Action research is a research methodology conducted by teachers to find scientific and practical solutions to immediate classroom problems.

As defined by Kurt Lewin and later expanded by Stephen Corey, it follows a continuous cyclical process:

• Planning: Identifying the problem and developing a plan of action.
• Acting: Implementing the planned strategy.
• Observing: Systematically documenting the effects and gathering data.
• Reflecting: Evaluating the outcomes and modifying the strategy accordingly.

Therefore, option A represents the exact logical and scientific sequence of action research.
