July 11 – August 19, 2016
Instructor: Dr. Susan Han, firstname.lastname@example.org, Associate Professor, U of Massachusetts
Time schedule: Summer online course
Course Description: This course will include an introduction to the environmental and biological factors that contribute to postharvest loss of fruits and vegetables, commercial procedures of harvesting, handling, and storage of horticultural commodities, and specific handling information for commodities of various plant organs. Small-scale handling practices will be emphasized.
Required texts: None
Grading scheme: Grade will be based on:
- First exam (15%)
- Second exam (15%)
- Third exam (15%)
- Fourth exam (15%)
- Active learning activities (40%)
Exams. Exams will be a combination of different types of questions, including some problem-solving questions concerning real-world postharvest problems.
Active learning assignments. Active learning assignments will be created to provide students with hands-on experience for some of the concepts discussed in the course. An example of an active learning assignment includes a description of an experimental design so students can set up an experiment at home that is related to the concepts learned in lectures. Forms will be developed for students to collect data. Reports will be submitted through the course management website. Other active learning assignments might involve a real-world postharvest problem and students will be asked to resolve the issue. The due date of each assignment will be announced on the course management system.
