3. Method of Instruction:

This course will be delivered in a Flexible Learning Mode, mainly through Asynchronous (Self-Paced) Learning and Synchronous
Physical (Face to Face) and/or Online Instructions. The JBLFMU Learning Management System (LMS) will principally be anchored on
MOODLE and on ZOOM for virtual (online) classes.

4. ANTICIPATED SCHEDULE

This Course is delivered on an alternating 2-week Module schedule (a) physical (face to face) classroom or Virtual (online
through) Zoom; and (b) self-paced but with fixed dates for required ACTIVITIES and PERIODIC EXAMINATIONS. The
final examination and date of submission of all requirements shall be the designated last day of the 1 st Semester SY 2020
– 2021.

The Course is divided into nine (9) modules (representing a two-week residential study of 6 hours) which is
recommended for the student to dedicate at least 6 hours of study each module. To instill study discipline, each module
culminates with a submitted activity (discussion paper, work output, assessment, etc.)
The Course is divided into three (3) modules – prelim, midterm and finals. Eighteen weeks (usually composed of 3hr/week, for a total
of 54 hours) is dedicated for a 3-unit course per semester. During the prelim period, self-faced approach will be employed, with
scheduled/on demand consultation with the instructor. During the midterm period, face-to-face class sessions will resume. The class of
40 students will be divided into two batches, and if the class is scheduled on an MTh, the first batch will report to class on a Monday
and the second batch will report on a Thursday. The modules for midterm and finals will be utilized by the students in lieu of the time
in the classroom.
