Agenda

2

1. Why integrating lectures and lab exercises is hard?

2. What might be a process for doing so?

3. Using RDz as the portal to the Mainframe

4. Some examples: Lab 1: Integrated Development Environments Lab 2: Data Formats Lab 3: Hardware/Software Architecture Lab 4: Operating Systems Lab 5: Batch Workloads Lab 6: File Management Lab 7: File Management – Indexed Datasets

5. What do you need for success?

Teaching with Labs is Fun…

3

But hard… why? Students have different learning styles

Students learn at different rates

Students have different levels of interest

Students don’t read

Students main problem solving method is “trial & error” and Google

Lab-based courses are harder to teach: Students have questions at the same time You are a hostage to environment Not all problems are related to content

4

The Process Steps … Determine learning

outcomes Find the right course Match – course’s content to

experiential component
