N{odularApproach
the lDtroductory Courso in CoDputer Science
the objective of the project is to develop a nodular approach to the introductory
course iII conputer science which will enable each studelt to neet his or her individual
needs. This approach would be itrplemolted by dividing the seneste! into thlee equal tine
periods. Each student would then choose, from amongseveral offerings, a lectule and a
laboratory lpdule for each of the three periods. The choices nade by the student would
dependon backglound and career interests.
In the sulIler of 1978 nine nodules will be developed and a student inforalatiol systen
to aid i.n. course adninistration will be iDplenolted. During the 1978-79 acadenic yea"
the nodularizod coulse l{il1 be taught fo! the first tine.
During the suDtre! of 1979 a
data bank of exam iteDs will be developed, suitable progra@rin8 will be conpiled, and
eview and nodification of all nodules wi.ll tako Dlace. Ful1 i[DlenentatioD of the
odulalized course will occur in 1979-80.
'Ihe proposed course would nore efficiently
serve the co[puting needs of students in a
ariety of disciplines.
Silce this approach could be useful at othiir instituti.ors,
all
odulos will be designed to be tlansportable.
The Dodular approach {i1I be evaluated irl
a variety of ways altd the results of the project ri1I be presented at a national lreeting

This project instituted a nen modular, multi-path approach to treat a
variety of problens in the introductory conputer science course, Anong these
problens are norking with students of varied backgrormdsand interests,
providing nitrinal exposuxe to conputers for liberal arts students, nerging
students l4ith pri.o! expelience in conputing into the course, dealing with
the shortage of available staff, and providirg good problens, exanples, and
exanirtatiolrs,
A set of fifteen modules were developed for inclusion in this course.
These nodules were divided into lecture or probleh solving tiodules and
language nodules. This approach nade significant inprovenents ilr a1!. of the
problen areas nentioned above.
Based on data collected before and during the inplenentation of this
approach, significant iroprovenent resulted in student perfornance as
neasuled by cou:.se grades, student attitude neasuredby lower drop rate,
enrol lneflt incxeases, and student evaluations, and faculty attitude. The
developnelrt of this course will continue in the future as new rnodules are
added and o1d rnodulesnodified, In addition, a groring nurber of faculty t{il1
be involved with the teaching of this course.
The najor conclusion that can be drawn fron this ?roject is that this
