2. 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?

3. 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. 4 The Process Steps …  Determine learning outcomes  Find the right course  Match – course’s content to experiential component Course Candidates  Introduction to IT  Hardware & Software Architecture  Operating Systems  Programming  Database

5. Using RDz as the Portal… 5 Multiple Computing platforms :Windows, Linux, z/VM, z/OS, 3720 Emulator Database Connections
