A teaching-learning strategy in which small groups of students with different level of ability use a variety of learning activities to improve their understanding of a subject :

Question

Accepted Answer

Here's a detailed explanation justifying why Option 3, "Co-operative learning," is the correct answer and why the other options are incorrect:

**Why Option 3 (Co-operative learning) is the Correct Answer:**

Co-operative learning is a teaching-learning strategy that perfectly aligns with the description provided in the question. Here's why:

*   **Small Groups:** Co-operative learning inherently involves students working in small, structured groups. This is a fundamental characteristic of the approach.
*   **Different Levels of Ability:** A key element of effective co-operative learning is the intentional grouping of students with varying skill levels. This heterogeneity allows for peer teaching, mentoring, and scaffolding, where more advanced students can assist those who are struggling, and all students benefit from explaining concepts to others.
*   **Variety of Learning Activities:** Co-operative learning encompasses a wide range of activities designed to promote interaction and engagement. These activities can include jigsaw puzzles, think-pair-share, group investigations, and structured discussions, all aimed at deepening understanding.
*   **Improve Understanding of a Subject:** The primary goal of co-operative learning is to enhance students' comprehension of the subject matter. By working together, students can clarify concepts, share perspectives, and build a more robust understanding than they might achieve individually. The structured interaction and accountability within the group setting foster deeper learning.

**Why the Other Options are Incorrect:**

*   **Option 1: Multi-sensory learning:** Multi-sensory learning focuses on engaging multiple senses (visual, auditory, kinesthetic, tactile) in the learning process. While it can be a component of co-operative learning, it is not a teaching-learning strategy that inherently involves small groups with different ability levels working together on a variety of activities to improve understanding. It's more about *how* information is presented, not *how* students interact to learn.

*   **Option 2: Team teaching:** Team teaching involves two or more teachers collaboratively planning, instructing, and assessing students. While it can be beneficial, it doesn't necessarily involve small groups of students with different ability levels working together on a variety of learning activities. The focus is on the teachers' collaboration, not the students'.

*   **Option 4: Programmed learning:** Programmed learning is a structured, self-paced instructional method where students work through a series of small steps, receiving immediate feedback. It is typically an individual activity and does not involve the collaborative group work that is central to the question's description. It also doesn't inherently address different ability levels within a group setting.

In summary, co-operative learning is the only option that directly addresses all the key elements described in the question: small groups, different ability levels, a variety of learning activities, and the goal of improving understanding of a subject. Therefore, it is the most appropriate and correct answer.
