. This isthe first laboratory experience with clocked devices. The problem specifications are as follows: a. The green light duration must be at least twice as long as the yellow light duration. b. The yellow light duration will be one or two units of time. One unit of time is one period of the clock. c. Before turning green for either road, the lights for both roads must be read for at least one unit of time. d. The conditions of both roads having a yellow light or both having a green light must never occur. This problem may be solved using a counter with sixteen different states. For example theinitial state of the counter C3(MSB) = 0, C2 = 0, C1 = 0 and C0(LSB

Much of this student’s contribution was outsideof the classroom. The first student received an poor score for participation, while the secondreceived an excellent score.Students tended to be very generous with the evaluations of their teammates.

the myth of "scientific method,"which seems to prescribe a sequence of (a) observing – undirected, at random, (b) experimenting,(c) forming hypotheses, (d) theorizing. In fact, most scientific experiments are performed afterhypothesizing, and are conducted mainly with the view of confirming the hypothesis. PeterMedawar said: Scientists don't ask questions very loudly until they can see the beginnings of ananswer. Any observations that run counter to the hypothesis are initially discounted, ignored, andtheir significance down-played or denied. Conducting scientific investigations requires someflair, ability, intuition, etc. to produce valuable additions to knowledge (these are usually classedas artistic traits).

These interactive activitiesare continued and lead to the property of two-force members (Figs. 9 and 10).A similar guided, inductive approach is used to develop properties of curved members (Fig. 11)and three-force members (Fig. 12). If the member load is moved to joint b, the three-forcemember (Fig. 13) becomes a two-force member. Investigating straight and curved, two-force andthree-force members in context reveals what they have in common and how they differ. Itprovides connections that facilitate the construction of knowledge. “In order to understand whatsomething is, one must also understand what it is not.” (Arons, 1990, p.92)Learning Environment and

A fairly significant fraction of the short time we did have was spent on dealingwith some issues related to the Unix operating system.Increasing the number of hours of tutorial sessions for Aspenplus alone at junior andsophomore level classes is impractical for two reasons: a) it will take contact time wayfrom regular classes where students are taught the fundamental concepts and b) thedifficulty of running such tutorial sessions on top of other teaching responsibilities duringregular semesters.Our objectives are to help develop in students the discipline of critical thinking and theability to solve problems.

It also compels thestudent to assess the performance of the other members and practice peer evaluation, asprofessionals (especially those in supervisory positions) must do in industry.

In Avionics I the students perform lab experiments wherethey characterize the ARINC 429 Data Bus by generating ARINC 429 messages with aJCAir 429 transmitter and record voltage waveforms using a Digital Storage Oscilloscope(DSO). Figure 6 shows a typical ARINC 429 waveform.The students also characterized RS232 signals using a PC Com port as the source of theRS232 signal and performed conversion from RS232 to TTL and vice versus using linedriver and receiver chips (1488 and 1489). The same chips can be used to convert the LineA and Line B ARINC 429 signals to TTL levels and from there combinational logic can beused to extract the ARINC clock

The role of distance engineeringis assessed by comparing group performance for two cases: one in which student group membersworking at remote locations can only use electronic means for communication, and another inwhich no constraints on communication are imposed.

The second alternative may seem more difficult to integrate into an existing courseoffering, but will likely provide long-term benefits to both the students and the department.2.1 Integration into Existing CoursesWe use our own Department of Mechanical Engineering (ME) at Virginia Tech as a basis forexploration.
