The teacher may pose a question or a situation or a scenario to involve the students. This is the best technique to let students express their ideas and lets teachers tap their creativity levels. Project The project method is a teacher-facilitated collaborative approach (in which students are divided into small groups) in which students acquire and apply knowledge and skills to define and solve realistic problems using a process of extended inquiry. It is a whole-hearted purposeful activity proceeding in a social environment. Projects are student-centered, following standards, parameters, and milestones clearly identified by the instructor. Lecture This method refers to the explanation of the topic to the students through oral presentation of information, principles, concepts, ideas. The emphasis is on the presentation of the content. The teacher clarifies the content matter to the students by using gestures, simple devices, by changing voice, change in position, and facial expressions. Teachers are more active and students are passive but the teacher also asks questions to keep the students attentive. It saves time and also covers the syllabus. It is the simplest method for teachers and does not require any arrangements. Collaboration It is a method of teaching and learning in which students team together to explore a significant question or create a meaningful project. A group of students discussing a lecture or students from different schools working together over the Internet on a shared assignment are both examples of collaborative learning. Hence, the main idea is sharing experiences, ideas and attitudes Discussion The discussion method of teaching is a group activity involving the teacher and student to define the problem and seeks its solution. It is also described as a constructive process involving listening, thinking as well as the speaking ability of the student. Therefore, option 4 is the correct answer.
