Blended Learning Exercise - Auditory Pathway - Sanjoy Sanyal
Blended (Hybrid) Learning refers to a combination of Online and Lecture-based Instructional Learning. In this exercise, a Blended Learning Pilot Project was conducted. The Auditory Pathway was selected for the exercise, in view of its relative complexity.
A video link was given to the students as a Pre-learning assignment. Next day in class, a series of Pre-lecture questions were asked before the start of the lecture. This was to test how much the students had learnt BEFORE the class.
After the lecture, a series of Post-lecture questions were asked.
Finally, after the whole exercise, students' feedback was obtained using the Clicker-based Audience Response System (ARS). The feedback was eye-opening indeed!
Learning Outcomes
After watching this Slideshow, the viewer should:
Know what is Blended (Hybrid) Learning
Be able to conduct a Blended Learning exercise of their own
Know something about the Auditory Pathway itself (though this is not a primary objective of this exercise)
Know how an Audience Response System works (at least partly!)
Have an idea as to how the students’ mind functions

Blended (Hybrid) Learning refers to a combination of Online and Lecture-based Instructional Learning. In this exercise, a Blended Learning Pilot Project was conducted. The Auditory Pathway was selected for the exercise, in view of its relative complexity.
A video link was given to the students as a Pre-learning assignment. Next day in class, a series of Pre-lecture questions were asked before the start of the lecture. This was to test how much the students had learnt BEFORE the class.
After the lecture, a series of Post-lecture questions were asked.
Finally, after the whole exercise, students' feedback was obtained using the Clicker-based Audience Response System (ARS). The feedback was eye-opening indeed!

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
