	This manuscript describes the use of internet for instructional 
purposes.  The experience reflects trial and error, and a perception of the 
broader developments in instructional technologies, such as the 
Western Governors' Association Virtual University. [1]  After climbing the 
initial steep trajectory of the technical learning curve of internet literacy, 
the next priority was ensuring quality within this new electronic context.  
One of my first efforts was to identify the best internet related teaching 
ideas with respect to economics instruction.  I developed a resource page 
based on this effort, Netteach. [2]  Recently, I've focused more intently on 
the development of specific course related materials and how the internet 
medium adds to and alters the teaching and learning environment.  The 
following is one dimension of this exploration.

INSTITUTIONAL CONTEXT
	The majority of students in my classes work full time and many 
spend significant amounts of commuting time to attend on-campus courses, 
which is one of the motivations for Middle Tennessee State University (MTSU) 
offering courses at different corporate sites--e.g., Nissan, Saturn, and 
Bridgestone.  Therefore, internet has emerged as a viable supplementary 
delivery system for access to and provision of instructional and research 
materials.  The average class size upon which the following experience is 
based is approximately 15 students, with a range between 5 and 30.  Thus 
far I have taught ten classes (some repeated) with internet infusion.
	While free internet accounts are provided to MTSU students, two 
immediate considerations arise for remote classes and access.  First, 
would students have access to a computer, and consequently a modem?  I found 
that most students did have a computer at home, but had never used the modem.  
Second, would students using MTSU accounts from remote sites resist paying 
long distance charges for a modem link to the campus computing center?   
Actually, the Saturn (Columbia, Tennessee) area was of primary concern.  
However, students who were Saturn employees were spared the long distance call 
since the company had a special local charge arrangement.  Several students, 
were not Saturn employees but were taking the courses at the Saturn 
site.  A few opted not to pay long distance tolls, either used Internet 
connections from their places of employment, or purchased a commercial service.
Beginning in the Spring of 1996 the university made a specially negotiated 
commercial service arrangement available to students.  Students taking 
courses on campus have liberal access to labs.  I estimate that 
approximately half of these also had modem access from home or work.

ELECTRONIC INFRASTRUCTURE 
	Electronic communications, research, test components, and 
comprehensive web pages have been integrated into five courses I have 
taught over the past year.  These courses are: micro-economic principles, 
a graduate level managerial economics course, a graduate level industrial 
relations course, an undergraduate/graduate labor economics course, and 
an undergraduate/graduate employee benefits course.  The managerial 
economics, industrial relations, and labor economics courses were taught 
off campus at the Saturn Corporation training facilities.  The web pages 
for each of these courses and the other resources cited herein are all 
accessible from my homepage. [3]
	The typical course web page has links to general resources 
germane to the course content, uploaded files of past exams, practical 
problems and a syllabus.  Embedded in the syllabus by class dates are the book 
chapters to be covered, electronic lectures, and for many lessons, an internet 
link directly applicable to the topic covered.  Suggested paper topics 
and internet use tips are also included.
	Supporting the course web pages are a number of other components of 
this instructional infrastructure.  First is the professional internet 
resource pages I developed for public use.  There are two significant 
reference documents.  The Industrial Relations & Human Resource Page [4] 
contains links to such sources as the U.S Bureau of Labor Statistics data 
bases and the Cornell Law Library.  The Benefits-L Resource Page [5] is a 
prominent web page offered for public access to support professionals in 
the employee benefits field.  Examples of links include the Social Security 
Administration, pension related materials, health care related materials, as 
well as commercial pages with significant public offerings.  Also, on-line 
examples of employee benefit plans are included.
	Actually, the Benefits-L web page was initially constructed to 
support the Benefits-L internet discussion list which I manage. [6]  With 
over 600 subscribers, there is a wealth of practical problems which are 
brought to light and excellent related advice offered.  I require all students
in my benefits course to subscribe to this list.  In other courses, such as 
industrial relations, students are required to subscribe to a course related 
list.  Examples include the International Employee Relations Network 
(IERN-L) and Human Resources Network (HRNET). [7]  Finally, students must 
subscribe to a College of Business discussion list, The_Biz, in order to 
receive college and department announcements.  Academic advising 
announcments will also be initiated on this list. [8]
	Although I impress upon my students that technology does not preclude 
face-to-face consultations, there seems to have emerged a near complete 
dependence on the electronic medium.  I suspect this is due to 
the convenience offered, especially in light of the heavy work schedules 
and commuting requirements.  Most rewarding is the continued contact with 
several students long after they have completed a course I taught, and in 
several cases even after they have graduated.  In all fairness to my 
institution, I have been given considerable flexibility in control of my 
time (meaning very few structured time commitments aside from class 
contatct hours), I think a fair exchange for the hundreds of hours of 
uncompensated additional work time required to develop and integrate an 
electronic framework to support instructional retooling.

PEDAGOGY
	Cultivating a discipline of the mind presents a different kind of 
challenge in the electronic environment.  Recasting the course an 
electronic image so the intended content is still imparted is a significant 
teaching challenge.  But there is an elevation of the  mental 
self-discipline required of students as well.  For this reason, I think 
courses which are exclusively in the realm of distance learning via the 
net should have a higher threshold of permission for enrollment.  Where 
internet serves as a supplement to traditional classes, students must 
have or obtain the requisite technical skills immediately.  I try to 
remedy this by a lab visit the first session.
	Traditional materials like books and journal articles have not 
gone away, yet.  I still rely on books because they tend to be thorough and 
convenient (i.e., portable).  But in my major fields upper division texts are 
especially deficient in offering disks of data and on-line references.  The 
latter is the targeted niche for my work in the internet medium.  If we are 
honest with ourselves, I think we recognize that we can't heap on electronic 
readings without trading off traditional hard print.  Only a small percent of 
students are prepared to commit soul and life to the pursuit of 
knowledge.  These intellectual stars are usually very good at following their 
own academic compass.
	What we can do for the majority generates the more intriguing 
questions.  For one, can all this electronic infrastructure generate more 
efficient trade-offs?  I have already mentioned the greater convenience of 
communication.  If nothing else, e-mail is incredibly efficient, not only in 
managing communications, but in keeping files.  For example, I keep electronic 
files of significant e-mail correspondences specific to each course, deleting 
the file after the end of the semester.  I am particularly keen on this idea 
for students pursuing independent studies since documenting agreed upon 
study plans, timetables, and monitoring of continuity of progress are 
crucial.  (I no longer accept students in such status unless they are skilled 
internet users.)  
	One other supervisory activity in which I've found this format 
effective is student teaching internships.  (MTSU has a Doctor of Arts in 
Economics, which requires an internship.)  For example, I require an 
electronic log to be kept by the intern on content or pedagogical questions.  
We review the learning experience at the end of the semester with this 
quick reference before us.
	Another dimension of efficiency is research.  Though I admit the 
risk, I have taken the leap of faith that most of the quality resources 
sufficient for student research papers are, or will eventually be, on the 
net.  Our library has advanced these possibilities by purchasing on-line 
services which provide full text journal articles sufficient for at least 
upper division undergraduate work.  My approach has been to integrate 
internet material which I consider more of a cutting edge nature.  A 
caveat here is that reliance should be placed on stable links (likely to be 
on-line for the foreseeable future), which I find are usually university or 
government links.  Also, credibility of the source is a very important 
consideration.  Finally, the compact I make with my students is that there 
will be no hard print reserve readings and no copying.  Everything will be 
transmitted to them electronically, or if necessary I'll provide a hard 
copy at no cost. 
	One of the most important aspects of efficiency gains is the 
re-allocation of time.  If the more mundane tasks and relaying of information 
which require class contact hours can now be handled electronically, what do we 
do with the extra time--more lectures, more readings, more of the same?  
These are not viable options in the competition for students' time.  
My experience is that I have been freed to focus on the in-class learning 
experience.  This has meant including more team exercises, presentations, and 
the introduction of more impromptu problems.  As a traditional instructor 
this transition has been somewhat painful and is mightily incomplete, but 
I suspect this is where the real payoff in terms of the increased quality 
and quantity of student learning will eventually materialize.
	The physical environment of the classroom and the particular 
course taught significantly affect the in-class activities.  For example, in 
the Labor and Human Resource Economics course, I have integrated a 
considerable amount of information system problems with extensive spreadsheet 
applications.  I try to teach this course in or in near proximity to a lab, 
though as more students have laptops, location is less of an issue.  For 
more qualitative problems in the areas of human resources or benefits, the 
impromptu problems or discussion list messages and threads have worked 
well.  But I am very mindful of tying the problem to the text material 
scheduled for coverage.
	Before departing from the efficiency theme, I am compelled to 
comment that I do not believe any of the electronic media will improve 
overall educational quality if myopic objectives are governing 
implementation, such as increasing the student to faculty ratio.  The 
intensity of time required to develop a sound infrastructure, and the 
intensity of guidance necessary for each student increases in this 
environment.  Since I have engaged the instructional possibilities of internet, 
I have not been overwhelmed for two reasons.  One is the wide latitude given 
by my university to experiment and pursue internet possibilities.  The other 
is the high attrition rate in my classes during the first two weeks, 
especially since many students historically gravitated to the types of 
courses I teach because of the absence of quantitative and computer 
oriented technologies.  This attrition has in the past year been less 
pronounced since students are more exposed to internet from other sources.

EXAMINATIONS
	Testing options are greatly expanded within the electronic 
environment.  A numerical itemization is perhaps the most efficient way 
to rely options I have tried.  These will progress from those which 
depart least from traditional methods to those most adventuresome.
	Items one through five evolved primarily to impress upon the 
students the necessity of periodically checking their e-mail to drive 
home the point that this is not a frivolous exercise.  I try to adhere to 
the principle of asking students to allocate time to learn material 
with a high probability of being directly related to their grade.  Also, a 
nice feature of e-mail is the date and time recording of messages.

(1) Pop quizzes and bonus point questions have been posted to classes 
with deadlines for responses.

(2) Traditional in-class exams have included a question for which only an 
e-mail response is accepted.  A word limit is imposed.	

(3) Students are given the option of elaborating upon in-class answers to 
questions by e-mail.  They can not add completely new material, but can 
clarify answers for which they felt in-class exam time was insufficient 
for thoroughness.

(4) E-mail follow-up inquiries are made of students concerning unclear 
aspects of their answers to in-class exams.

(5) Messages posted to discussion lists to which students are required to 
subscribe are included as parts of exams.  E.g., students are asked to 
interpret the message within the context of the course material covered.

(6) Entire exams have been e-mailed to classes at fixed times, with a 
fixed amount of time to respond.  One limitation is the text bound nature 
of responses.  I did this in one fairly technical economics course in 
which graphics and equations were commonly used.  Students commented on 
the difficulty of reducing their answers to words.  I thought this in itself 
was an interesting intellectual exercise, but gave them the option to clarify 
via an in-class presentation of their exam answers--only if they were 
prepared to wager points (I.e., they could gain or lose exam points 
depending on the quality of their presentation.)

(7) The most intensive integration of electronic testing was an 
accommodation for masters level comprehensive examinations.  Due to 
highly flexible arrangements with a student for independent studies I was 
concerned about the quality of instruction and learning.  Therefore, I added 
a series of evaluations around the traditional comps.  Essentially, a few days 
prior to the on-campus exam, I e-mailed the student (in a remote part of the 
state) a "preliminary" exam to which he was to respond via e-mail.  After I 
read his on-campus comp results, I then e-mailed some follow-up questions with 
a response deadline.  Finally, we set a meeting time and I asked for further 
oral clarifications and then reviewed my evaluation of his performance.

	My experience keeps bringing me to a couple of substantive 
philosophical issues related to examinations given the nature of our 
information age.  One concerns the drive for standardized assessment in the 
name of accountability.  Standardization has a place, and to some degree, 
books, electronic teaching devices (e.g., multi-media), and even electronic 
test scoring devices themselves lead us down this path.  However, there is 
something quite different with on-line interactivity.  Qualitatively, the 
ability to modify the teaching/learning process in real time, the 
capacity to follow-up on exam results, and the "learning to learn" objective 
of higher education do not fit the standardization philosophy.  As teachers, 
we must not allow standardization to become the blanket option in the 
evaluation of the intellectual development and promise of our students.  
	The second point concerns how the universe of information, especially 
on the internet, is spilled all over the educational landscape.  We must ask 
ourselves if testing by denying access to information makes sense in a world 
in which the intellectual productivity is more geared to squeezing value from 
information abundance.  Again, sometimes a bit of experimentaiton 
required to break the mold.  My petite iconoclasm is that or three years now I 
have allowed open book exams in all my courses.  Generally, the most successful 
students customize the course material into an intellectual framework which 
organizes and integrates the content (i.e., they conscientiously keep up 
and outline the material).  I think the exams are more difficult in 
this environment, but more reflective of the employment environment for which 
we are preparing them.
	Though I have not perceived that cheating has been a problem in 
the traditional versions of the courses described above, clearly the 
open-book format eliminates the payoff of cheating by using hidden 
information.  Another by-product is that in some cases the electronic 
forum of testing offers options to accommodate student disabilities.

PAPERS
	The internet has changed the options for the traditional 
paper at least as much as it has for exams.  Being very much a traditionalist 
with respect to vigilance against plagiarism I require students to give very 
precise internet citations.  I want to examine the primary source if I so 
choose.  However, the impossibility of close scrutiny is evident.  There is 
simply too much information electronically available now to allocate more 
than minimal time to control for electronic plagiarism.
	One solution is not different from the pre-internet days.  
Verify the intellectual capacity and performance of the student by requiring 
presentations and asking lots of questions.  The modification I have made 
is to require shorter papers and more in-class presentation to explain the 
findings.
	Research on the net offers some other very interesting 
possibilities.  Web pages and data bases abound in some fields, my 
teaching areas of labor, human resources, and benefits being well 
represented examples.  For the particularly qualified student, researching 
discussion list archives can yield a treasure of practical insights into many 
professional fields.  
	One word of strong caution is in order.  Some students join discussion 
lists and ask for help on papers, and others have gone so far as to devise 
questionnaires and post them.  At least for the internet discussion lists with 
which I am familiar, this is inappropriate behavior.  A significant problem is 
that many faculty are not as versed with the internet as are their students, 
and thus proper guidance is not given.  Though I applaud student 
initiatives, an unguided foray into the net can reflect poorly on the 
the institution and faculty member.

LESSONS LEARNED
	Clearly, my experience is anecdotal, but in a sense the net is a big 
anecdote of our time.  The best we can do right now is try to make good 
qualitative decisions.  I hope this text has lent insights into this effort.
The following lessons have lingered longest with me.

(1) The greatest efficiency in terms of economizing on instructor and 
student time has been in e-mail use and a commitment to provide reading 
materials on line.  For some students on-line research for papers has 
saved time, but most students still have a significant learning curve if 
they are inexperienced users.

(2) Students will "buy in" to convenience, especially in an environment 
where commuting time is significant and classes may be dispersed to 
off-campus sites.  This convenience motivates them to gain on-line access 
from home, work, or other sites.

(3) Maintaining quality in a course highly evolved toward an electronic 
infrastructure requires intense focus on how the technology should, and 
should not, be employed.  Experimentation with different learning 
configurations to maximize the advantages of the technology is 
essential.  The faculty member must find the effective combination of 
his/her own experience and style with the opportunities presented by the 
technology.  This suggests a fundamental re-thinking of how we allocate 
teaching time.  For example, I have become less and less likely to lecture 
on material covered in the book, and more likely to strike out into 
related areas of research or engage the class in impromptu problems. 

(4) Students are accountable for more material not covered in class.  I 
make this point very clear, and reinforce it with test questions.  
Bluntly put, this means students must learn more on their own by reading 
the text.  The demonstration of what they've learned with in-class 
application seems most crucial.

(5) One question is ever present in our new techno-glitz educational 
environment.  Is the student better educated?  Much of what we are about in 
higher education is based on faith (i.e., truth in its multiple dimensions).  
The advances at this stage are more tactile than visionary.  We've just got to 
do it, and through this process figure out how to do it better.  I think there 
is too much hype in hyper-education.  We need more harness.

(6) An electronic infrastructure potentially extends educational 
possibilities to more people who would otherwise not pursue higher learning.  
If fact, this is a component of the unfolding agenda of the Tennessee Board of 
Regents.  Students may be enthusiastic, but woefully unprepared for the rigor, 
wrongly attributing the old model of correspondence courses to this more 
demanding and more interactive environment.  

FUTURE DEVELOPMENTS
	I have to date only taught each of the courses mentioned in this 
manuscript one time with the full complement of web page and other 
electronic support systems.  The next wave will incorporate web page 
elaboration, tighter editing, and more attentiveness to on-line data bases.  
Having experimented with one custom published text, I am also interested in 
the possibilities of meshing these selective materials with internet 
resources.  More data disks compatible with spreadsheet applications are also 
on the horizon.
	Another more immediate objective is to develop on-line cases for 
student teams, dispersed in different locations.  I expect this to be 
quite time consuming, but but promising of some interesting pedagogical 
insights.
	In the fall of 1996 I will broadcast a graduate managerial 
economics course and in the spring of 1997 I am scheduled to broadcast a 
benefits course from MTSU's distance learning room.  These experiences 
will yield some opportunities to experiment with syncing internet with 
broadcasting systems.  Also, individual and group presentations by 
students via telecommunications systems suggest other avenues to explore.  
	There are two projects for which I have longer term leanings.   
One is the development of a CD for one of my courses.  MTSU has the 
production facilities for this kind of effort.  The other project is, for 
lack of a better term, a "living text."  Conceptually, this would be an 
on-line text with continuous work in progress.
	From my experience on the net during the past four years, I also 
am intrigued by another development.  This is the blending of faculty, 
students, and practitioners--typically within discussion lists. [9]  These 
new internet patterns raise interesting questions about the universality 
of the learning experience and who and where the intellectual resources 
are.
