Variable Operationalization<br />
Our variables were constructed from the grades that<br />
students received on each of their polished and final<br />
analyses. The writing consultant and instructor<br />
provided detailed feedback and a score, based on a<br />
grade point evaluation scheme. They provided an<br />
overall writing score and an analysis score – the<br />
maximum a student could receive on each of these<br />
was a 4.0 translating to an A. In addition, the writing<br />
consultant provided a breakdown of the writing score<br />
on the following five components: argument,<br />
evidence, format, writing rules and appendices.<br />
Each of these components received a grade-based<br />
score as well. The construction of the criteria is<br />
explained in Exhibit 2. We used only the argument<br />
and evidence components since the other<br />
components were aimed at writing style rather than<br />
toward developing logical thinking. In addition, we<br />
collected information on the students’ gender, with a<br />
binary variable, 1 if female, 0 if male; the number of<br />
transfer hours; their earned GPA on required<br />
university writing classes (prior to business major<br />
admission); and on the business required writing<br />
class (subsequent to admission to the business<br />
major).<br />
Sample Description<br />
In general, we had fewer female students, 20<br />
percent, which was representative of the population<br />
at the Business School. Our students joined the<br />
university with an average of 34 transfer hours and<br />
tended to transfer from a variety of institutions, two-<br />
and four-year colleges as well as nationally<br />
recognized research universities. The student grade<br />
point average (GPA) in the required university<br />
writing class taken prior to admission as a business<br />
major, as well as the required Business Writing<br />
class, was 3.61 and 3.79, respectively. Although this<br />
seemed to indicate that our students were prepared<br />
for writing and had done well in their writing classes,<br />
receiving grades of B+ to A-, our assessment was<br />
that the high GPAs represented grade inflation<br />
rather than a representation of student ability to<br />
write. This was further confirmed by the lower<br />
averages on the writing and analysis scores, as well<br />
as the components of argument and evidence<br />
received on the cases that ranged from 2.39 to 3.16,<br />
suggesting that student writing ability was in the C to<br />
B range. Our statistics did indicate an improvement<br />
due to the feedback provided on the polished draft;<br />
all final draft scores, writing, analysis, argument and<br />
evidence, were consistently higher than the<br />
respective polished draft scores<br />

Findings<br />
We ran three sets of regressions to explore the key<br />
influences on student writing ability. The lack of<br />
consistent records across students and across<br />
semesters led to samples of different sizes across<br />
the three regressions. Our first set of regressions<br />
explored the effect of student characteristics of<br />
gender, transfer hours and GPA on prior writing<br />
courses. The second set of regressions examined<br />
the effects of student learning by regressing the<br />
scores received on the first case analyses on the<br />
scores received on the second case analyses. The<br />
third set determined the value of revision and<br />
rewriting a case analysis by comparing the polished<br />
draft and final draft scores. We first discuss the<br />
effects of student characteristics on writing ability<br />
(Table 2).<br />
