One was a collegegraduate in a non-engineering position, one a machinist, one a welder (with very little self-confidence) and other a factory laborer. The data collection process was not coordinated and thedata sheets were not very well organized. The welder and the factory laborer were slower to pick upthe course material. Two members essentially picked the parts they wanted to do and left the restfor the other two. There was little coordination or cross

relationships of the differentrung elements, from which the ladder diagram can be readily derived. (My students gain somefamiliarity with Boolean algebra earlier in the course.)Figure 2 illustrates this alternative approach. From the problem statement, a simple diagram of afan and two control switches is drawn (A). Then, since the problem statement says that the fan isto be controlled from both locations, arrows are drawn from the control switches to the fan. Next,a Boolean expression (B) describes the logic for the only output in the system, the fan. In English,the Boolean expression reads, “The fan is true (or on) if Start1 or Start2 is on, or if the fan is on
