* Age appropriateness: The content, activities, and assessment methods should align with the students' developmental stage, learning styles, and prior knowledge. A lesson plan that introduces complex calculus to kindergartners lacks common sense.
* Realistic time allocation: The plan needs to realistically estimate the time required for each activity. Over-scheduling leads to rushed lessons and stressed students, while under-scheduling leads to wasted time.
* Clear objectives and learning outcomes: The lesson should have well-defined goals that are measurable and achievable within the allocated time. Students should know what they are expected to learn and how their learning will be assessed.
* Variety of instructional methods: Using a range of strategies (lectures, discussions, group work, hands-on activities, technology integration) caters to diverse learning preferences and keeps students engaged. A lesson solely consisting of lecture, for example, lacks common sense for most learners.
* Logical sequencing and flow: The lesson plan should have a clear progression of ideas and activities, building upon previously learned concepts. A haphazard, disjointed lesson lacks common sense.
* Effective classroom management strategies: The plan should consider how to manage student behavior, transitions between activities, and potential disruptions. Failing to plan for potential classroom issues lacks common sense.
* Accessibility and inclusivity: The lesson plan should consider the needs of all learners, including those with disabilities or diverse learning needs. Failing to make accommodations is a lack of common sense.
* Appropriate resources and materials: The plan should specify the necessary resources (books, technology, supplies) and ensure they are readily available. Assuming students will magically have everything they need is a lack of common sense.
In essence, common sense in a lesson plan is about practicality, effectiveness, and a deep understanding of the students and the learning environment. It's about making sound judgments based on experience and best practices to create a lesson that is both engaging and productive.
