Maybe I shouldn't have started this blog now, not with everything that's been going on.

In the second working session of my Computer Systems Organization lab class during the last day of the third week of the third term, since they already knew how to connect chips of basic logic gates to the breadboard and activating them, we then went to simple Boolean functions applied.

I gave them two functions of two variables each and one function of three variables that they were supposed to get the truth table to, maybe proceed to the K map, and draw a circuit for.

Then they had to connect this circuit given only one chip of inverters, one chip of and gates and one chip of or gates.

On a side note I’m surprised the word processor’s grammar checker did not find anything wrong with the previous sentence without quotation marks.

I stayed up front of the room with the power supply and the voltage reader, waiting of each of the groups to finish their circuits then approach me.

If the truth table they presented did not match with the outputs of their circuit when the inputs were varied accordingly, then they would step aside and let another group test their circuit.

When they returned to my table, they had to be able to tell me if the problem was with their truth table, their schematic diagram or their physical connections.

There were already a couple of groups who had different truth tables and circuit outputs for just the first function.

The majority of those who had the same truth table were complaining that I should give the first group a low score because the first group’s truth table was different from the rest of the class.

I did not relent though because my basis for the grade was that the truth table should match the output of the physical circuit, which the first group had fulfilled.

Of course, things will become less malleable as I give them more complicated functions so that I promised them I would teach them how to troubleshoot next meeting.

Session 967’s data didn’t match. Class dismissed.
