What did Jay Lemke discover in regards to science education?

Jay Lemke has studied dialogue during science lessons among students and between students and teachers (1990). The classroom talk register, then, constrains how communication between teachers and students can take place, but it also gives teachers and students a “language” for talking about teaching and learning.

Why is it necessary to consider a language in principles of teaching?

Teachers and students use spoken and written language to communicate with each other–to present tasks, engage in learning processes, present academic content, assess learning, display knowledge and skill, and build classroom life. In addition, much of what students learn is language.

What are the negative effects of online teaching for the teacher and the taught?

Online student feedback is limited.

E-Learning can cause social Isolation.

E-Learning requires strong self-motivation and time management skills.

What is the impact of online teaching on current level of education?

Online courses call for a greater amount motivation and self-discipline than a classroom-based course. A classroom has one or more instructors and peers, who can hold a student accountable for their course-work.
