They certainly should know more than their students in the subject matter they are teaching. However, this does not necessarily mean that teachers know more than their students in every area.
No more students No more tests I finally have Some time to rest
This is where the teacher tries out different methods meet the students needs. Not all students learn the same way so this type of learning can help more students can learn material.
A puppy is much more playful than an older dog. A kindergarten teacher needs to know when to be stern and when to be playful with her students.
Children with special needs may require extra attention, and more guidance than other students. They may also need more one on one time with a teacher.
A teacher exchange program exposes a teacher to the teaching methods and students of other countries. After such exchange, the teacher will (hopefully) know more about students from other countries (such as special practices, school structure and organisation, etc). This way, if a student from such country is in the teacher's class, he/she can help the student adapt more quickly. The teacher can also adapt more quickly if he/she goes to teach at a school in such country. This would develop a teacher as a global teacher.
Yes, to a point. As a teacher I need to know if my students have learned what they have been taught and I need to compare scores from the first of the year to the end of the year. BUT the test needs to be fair and testing the student on what they should know at their grade level. I say this because I gave standardized tests for years and in the testing today the students are getting tested on items that are above grade level. This is not fair to the student or teacher. I had students crying after the first day of testing and they still had 3 more days to go. Measuring students academic progress with other measures is needed and not all students test well. As a child I was one of those students that froze when tested. Education needs to show all levels of learning and testing.
Students get a lot more 1-1 time with the instructor. The instructor can get to know the individual students better which allows them to better identify areas where the student needs help. It woul;d probably also0 force the student to be more involved in activities and discussions as there would be less people in the room to take up the load
It allows for more one-on-one interaction between students and the teacher.
Classroom management plays a vital role in the way a teacher dishes out his or her lessons. With well planned out lessons, that are more learner centered, the class is effective, but When a teacher takes up the time to only lecture and give notes without being learner centered, s/he is derailed and becomes ineffective. The teacher needs to first identify the learning styles of the different students and address their needs appropriately by grouping students based on learning interest. .
It depends on the teacher. Some know much more than 18 year old students. Other English teachers do NOT know infinitely more than 18-year-old students. However, mylar balloons is not a topic that most adults really think about a lot.
I can say without a doubt, It is when the teacher's out.
What each and every student needs as basics in the classroom. Some students might need a little more hand holding but try to satisfy not only the equality of the classroom but also the equity you bring to each student. Also, an analysis of the students. Were are they with technology. See the kind of feedback you get and try to incorporate it into your curriculum. Most importantly, continue to educate yourself in the digital divide...be at the forefront of technology. Know more then what they know...and apply it to learning.
