42 Production Questions What is meant by Time is money!?
How is time a technological resource? How can we improve production efficiency? How do we reduce the average time per item produced? What do we do with the saved time? 43 Production Questions
How do we increase the production volume in a given period of time? Why would we change the order in which we perform tasks? Why/how would we combine tasks? What is a subassembly? Is there a right number of employees? 44
Production Questions Could we produce at the same rate with fewer employees? Which assembly method resulted in the lowest production time per vehicle? Why? Compare the production experience between the linear assembly line and the nonlinear assembly cell. Identify and explain the
strengths and weaknesses of each method. 45 Production Questions Is there value in individual production? How? Why? What is the significance of observations and recorded data in production? How would we chart or diagram these three
assembly methods? How would motion-time studies affect the profitability of a company? 46 Production Questions How do the following work skills and traits affect employers and employees? How do they affect your performance at school?
Team player Leadership and ability to follow leadership Adaptability Accountability 47 How did we learn?
48 Learning Theories Behaviorist - (Social Learning) students learned on the job Constructivist - students developed new knowledge through a process of active
construction Empiricist - students learned from that which they experienced Contextual - students learn from each other through cooperation, discourse, teamwork, and self-reflection 49 Learning Descriptors:
Tactile - hands-on, Interdisciplinary takes advantage of prior draws from information experience with playing and skills acquired in with Lego's several disciplines Visual - eyes-on, Cooperative - small
instructions are not group to whole group written, just pictures membership and participation Reflective - thinking about what was learned Fun - self explanatory 50
This is the only class where we can sit on the floor and play with Legos. 51 How do we know that we learned
what we learned? 52 Measurement?
