Does prior project management work experience have an effect on the academic achievement of university students in the classroom?
This study compared the academic achievement of students who participated in a cooperative education program (co-op students) with the academic achievement of those students who did not participate (nonco-op students). The general hypothesis was that students who gained knowledge through co-op work experience would use that knowledge in subsequent coursework and achieve a higher grade point average (GPA) than students who did not participate in the co-op program. Historical data were analyzed on students (N = 460) who graduated from the building science program at Auburn University from 1996 – 2000. The independent variable was STATUS (co-op vs. nonco-op) and the dependent variable of academic achievement was measured by the GPA of five sequential project management classes.
Construction Management Programs in Higher Education
The construction industry employs roughly five-million Americans and is a diverse, fast-paced, and large segment of the economy. Construction projects, equipment manufacturers, and material suppliers comprise approximately 10% of the GDP (gross domestic product) of the United States (Clough & Sears, 1994). Also, monthly housing starts, along with other construction indexes, are leading economic indicators of the overall health of the economy. The leadership and management of this industry impact the competitiveness of American businesses in the global economy and affect every person in the U.S. to some degree.
Supervision and project management positions in construction have historically been filled by craft workers who worked their way into the roles of superintendents, estimators, and project managers. Until 1945, the management of construction operations was viewed by many as a trade school occupation similar to a carpenter or electrician and was not considered an academic discipline. However, after World War II, there was a large demand for college-educated individuals who could understand engineering and business theory and use this knowledge to build complex construction projects around the world. This demand led to the formation of construction-specific academic programs being established in schools of architecture, technology, engineering, business, and applied sciences at universities throughout the United States (Robson & Bashford, 1995). The construction curriculum in higher education has evolved over the past 50 years and is now a combination of math, science, engineering, business, management, and construction science classes.
Background of the Issue
Past research studies have used high school class rank, high school GPA, ACT scores, SAT scores, age, and work experience as predictor variables to determine academic achievement in college students (Beecher & Fischer, 1999; Garton, Dyer, & King, 2000). This study focused on one of these variables that is currently being debated in construction management education, namely work experience (Chapin, Roudebush, & Krone, 1997; Hynds & Smith, 2001; Senior, 1998). The debate focuses not only on work experience, but structured, verifiable, and appropriate construction management work experience (Hauck, Allen, & Rondinelli, 2000).
Many college and university construction programs, that belong to the Associated Schools of Construction (ASC), are in favor of some type of mandatory construction work experience as part of their undergraduate curriculum. This work experience usually takes the form of a structured internship or participation in a cooperative education (co-op) program. Several ASC construction programs already require a minimum number of verifiable hours of construction work experience in a structured internship as part of the curriculum (Chapin et al., 1997; Hauck et al., 2000). While none of these programs require co-op participation, the requirement for mandatory construction work experience is growing.
The American Council for Construction Education (ACCE) is the accrediting body for construction programs in higher education. Since 1974, ACCE has accredited 52 baccalaureate degree programs and eight associate degree programs in the United States (ACCE, 2002). As of 2002, ACCE does not require construction management work experience for accreditation. However, many construction industry advisory councils and alumni have supported the idea of making it a required part of construction curricula across the country (Chapin et al., 1997; Hauck et al., 2000; Hynds & Smith, 2001).
Definition of Terms
Cooperative Education at Auburn University – The student must have a minimum cumulative GPA of 2.20 to be accepted into the co-op program. Co-op employers regularly interview on campus to fill co-op positions within their companies that match students' academic and career goals. The co-op student follows a formalized plan for the alternation of full-time classroom study with periods of full-time work experience. The co-op program involves a minimum of four quarters of professional work experience.
Cooperative Education Students (co-op) – Building science students who participated in the cooperative education program administered by Auburn University from fall quarter 1994 – summer quarter 2000.
Non-cooperative Education Students (nonco-op) – Building science students who did not participate in the cooperative education program administered by Auburn University from fall quarter 1994 – summer quarter 2000.
Student Status (STATUS) – The student will be classified as co-op or nonco-op. This is the independent variable for the study.
Grade Point Average (GPA) – Calculated by dividing the total grade points by the total number of credits attempted. Grade points for this study are: A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0. Therefore, if a student earns an A, B, C, and D respectively in four different classes during the quarter, the student's GPA would be calculated as follows: GPA = [(4.0 + 3.0 + 2.0 + 1.0) X 3 credits per class] / (3 credits per class X 4 classes) = 2.50
Acceptance into the Building Science Program – The student's classification was changed from pre-building science (1st and 2nd year) to building science (3rd year). Entrance into the program was competitive and was based solely on the student's cumulative GPA after all pre-requisite classes were completed.
Acceptance GPA (AGPA) – The student's cumulative GPA (after completing all prerequisite classes in the pre-building science curriculum) at the time the student was accepted into the building science program on a competitive basis. The acceptance GPA is computed by dividing the total grade points by the total number of credits attempted at Auburn University. This baseline variable, measuring initial academic achievement at the time the student was accepted into the building science program, was used to create four homogeneous groups of students.
- Group 1 (G1) – This group consists of students who had an acceptance GPA (AGPA) between 2.20 and 2.49.
- Group 2 (G2) – This group consists of students who had an acceptance GPA (AGPA) between 2.50 and 2.99.
- Group 3 (G3) – This group consists of students who had an acceptance GPA (AGPA) between 3.00 and 3.49.
- Group 4 (G4) – This group consists of students who had an acceptance GPA (AGPA) between 3.50 and 4.00.
Project Management GPA (PM GPA) – The student's GPA based on five sequential project management courses: estimating I, estimating II, construction scheduling, project management, and contracting business. The building science PM GPA is computed by dividing the student's total grade points by the total number of building science project management class credits attempted. This is the dependent variable measuring academic achievement for the study.
Research Question & Hypotheses
Research Question: Was there a difference in academic achievement, as measured by GPA, between co-op students and nonco-op students who graduated from the building science program at Auburn University from 1996 to 2000?
The following null hypotheses were developed for this study and a .05 level of significance was used based on previous studies done in this field (Appelt, 1991; Burton, 2000; Hauck et al., 2000; Ullrich, 1988).
Null hypotheses 1 through 4 investigated the difference between co-op students' and nonco-op students' PM GPA within the four homogeneous baseline groups G1 through G4.
- Hypothesis 1: There is no difference in the mean scores within group G1, as measured by PM GPA, between co-op students and nonco-op students at the .05 level of significance.
- Hypothesis 2: There is no difference in the mean scores within group G2, as measured by PM GPA, between co-op students and nonco-op students at the .05 level of significance.
- Hypothesis 3 : There is no difference in the mean scores within group G3, as measured by PM GPA, between co-op students and nonco-op students at the .05 level of significance.
- Hypothesis 4: There is no difference in the mean scores within group G4, as measured by PM GPA, between co-op students and nonco-op students at the .05 level of significance.
The focus of this study was to compare the academic achievement of building science students at Auburn University who participated in a cooperative education program with the academic achievement of those students who did not participate. Cooperative education research is a relatively young field with empirical studies starting in the 1960s (Lyons & Hunt, 1961; Smith, 1965). While the academic benefits of participating in cooperative education may seem obvious to some, researchers have conducted numerous studies over the past 40 years in an effort to describe, quantify, and provide evidence of such benefits.
Chapin, Roudebush, and Krone (1997) conducted a survey concerning the use of cooperative education within the 88 member schools of the Associated Schools of Construction. In this study, the definition of cooperative education also included internships and work-study programs. A major finding of the study was that 91% of the schools had some type of co-op program and that a majority of the schools (58%) required this experience in their curricula (Chapin et al., 1997). For the schools where the co-op program was voluntary, an average of 32% of the students chose to participate. While the benefits of cooperative education in this study were descriptive, opinion-based, and self-reported by faculty, co-op administrators, and department heads, some of the written comments from the questionnaire give a clue as to what construction educators believed about students' co-op experience:
- Students come back more motivated.
- Most demonstrate improved classroom performance as a result of the experience.
- Changes the quality of the performance in capstone course required at the end of the senior year.
- Provides direction to student. Helps motivate students when returning to classroom.
- When the experiences provide responsibility, the student matures in his discipline.
- Brings relevance to the students' classes.
- Students familiarize themselves with real-life situations. Tests reflect such situations. All curriculum tests reflect practical applications.
- Employers offer higher salaries to graduates with real experience.
- Graduates with co-op experience obtained higher entry-level salaries and were promoted much faster (Chapin et al., 1997, pp. 114-116).
These claims are based on anecdotal evidence because of the lack of empirical studies involving construction students and co-op education. However, many of these comments from construction educators reflect the same benefits that cooperative education researchers have studied over the years: (1) career maturity, (2) higher starting salaries for graduates, (3) academic achievement, (4) initial employment, and (5) motivation.
In their review of cooperative education literature, Ricks, Cutt, Branton, Loken, and Van Gyn (1993) took a critical look at previous cooperative education research studies. Ricks et al. (1993) stated that:
The cooperative education literature tends to demonstrate what is believed about cooperative education that is similarly defined, rather than what has been substantiated in cooperative education research. The literature contains many assertions, and sometimes postulates, that have not yet been adequately tested (p.11).
Therefore, when reviewing the literature about academic benefits associated with participation in a cooperative education program we are not surprised to find contradictory results and conclusions from four decades of research. Many empirical studies were conducted without taking into consideration initial differences between co-op students and nonco-op students when measuring outcomes after co-op participation (Ricks et al, 1993).
This study utilized a causal-comparative research design because the researcher did not have direct control over the independent variable. According to Ary, Jacobs, and Razavieh (1996), causal-comparative design is defined as ex post facto, Latin for from after the fact. This research was conducted after variation in the independent variable STATUS (co-op vs. nonco-op) was already determined in the natural course of events.
To help alleviate internal and external validity concerns from past research, this study looked at a very narrow, structured, and definable classification of work experience available to students: specifically, experience gained by building science students who participated in the cooperative education program at Auburn University versus building science students who did not participate. This narrower classification of work experience allowed for a longer treatment effect, four quarters of co-op experience versus 10 weeks of internship experience in the Hauck et al. (2000) study. The population for this study was larger than the Hauck et al. study, using 460 students versus 149. Finally, the time period for the treatment to take effect was two years versus one semester immediately after a summer internship in the Hauck et al. study.
This study used historical student data to measure differences in academic achievement between co-op students and nonco-op students. The independent variable was STATUS (co-op vs. nonco-op) and the dependent variable, academic achievement, was PM GPA (GPA of five sequential project management classes). In addition, a baseline measurement variable of academic achievement was conceptualized to categorize the students into homogenous groups based on their cumulative grade point average when they were accepted into the building science program, AGPA.
Typically the three entry points for new graduates in a construction firm are: (1) junior estimator (2) assistant project manager, and (3) assistant superintendent. If possible, co-op students working for a construction firm are rotated among these three positions in order to give the student a flavor of the work that the company does and the way that they do it. The co-op student would be exposed to professional practice among these three positions during the coop work experience. It was hypothesized that this exposure to professional practice in the construction industry would have an effect on the project management classes (PM GPA) in the curriculum. Also, grouping these five project management classes together provided a chance for co-op work experience to have an effect on a narrow set of classes, rather than getting lost in the total coursework credits that are used to calculate the student's graduation GPA.
A baseline measurement variable of academic achievement, AGPA, was created to categorize the students into homogenous groups in order to minimize the main threat to the study's internal validity namely, groups that are not comparable. The participants were categorized into four homogenous groups based on their grade point average at the time they were accepted into the building science program (AGPA). The four groups were: G1 (2.20 – 2.49), G2 (2.50 – 2.99), G3 (3.00 – 3.49), and G4 (3.50 – 4.00). This variable was created by calculating the student's cumulative GPA (after completing all pre-requisite classes in the pre-building science curriculum) at the time the student was accepted into the building science program. A t-test procedure was performed on each of the four groups to determine if there was a significant difference between co-op students' and nonco-op students' mean scores. The results are listed in Exhibit 1.
There was no statistical difference, at the .05 level, between co-op students' and nonco-cop students' mean scores of AGPA within each of the four groups. Therefore, the statistical analysis supports the study design of grouping the students according to their AGPA to establish a baseline in which to perform future comparisons based on dependent variables of academic achievement.
The final data set consisted of 460 building science students. Of the 460 students, 143 participated in the cooperative education program and 317 did not. The data for each student consisted of: STATUS (co-op vs. nonco-op), AGPA (cumulative GPA at time of acceptance), and PM GPA (GPA of five sequential project management building science classes).
An analysis of variance (ANOVA) procedure was performed on the participant data and determined that PM GPA means for co-ops (3.05) and nonco-ops (2.88), within group G2, were significantly different (F = 5.894, p = 0.0161) at the .05 level of significance (see Exhibit 2). The application of a second ANOVA procedure determined that PM GPA means for co-ops (3.45) and nonco-ops (3.27), within group G3, were significantly different (F = 5.274, p = 0.0238) at the .05 level of significance (see Exhibit 2). The PM GPA means for co-ops and nonco-ops, within the other two groups: G1 and G4 were not significantly different at the .05 level of significance (see Exhibit 2).
The results of the statistical analysis for hypotheses 1 through 4 are as follows: Null hypothesis 1 cannot be rejected, Null hypothesis 2 is rejected, Null hypothesis 3 is rejected, and Null hypothesis 4 cannot be rejected.
Co-op Participation and GPA in Project Management Classes
There was a significant difference between co-op students' and nonco-op students' PM GPA mean scores for two of the four groups. Interestingly, the co-op participation did not have an effect on group G1, comprised of the lowest range of AGPA scores (2.20 to 2.49), nor group G4, with the highest range of AGPA scores (3.50 to 4.00). The coop participation did have an effect on the two groups in between the highest and lowest ranges: G2 (2.50 to 2.99) and G3 (3.00 to 3.49). The results seem to suggest that the treatment, co-op participation, did not have an effect on the weakest academic group G1 nor the strongest academic group G4, but rather affected the two groups in between, G2 and G3. The students in group G4 were high academic achievers before they entered the building science program and typically would have been high academic achievers in their coursework whether they participated in the co-op program or not. Conversely, the students in group G1 were low academic achievers before they entered the building science program. These students may have had a much harder time grasping the academic content of the five project management classes and therefore, the co-op participation did not have a large enough influence on their GPAs to be significant. While the co-op students in groups G1 and G4 had higher PM GPA mean scores than the nonco-op students, the difference was not significant.
Limitations of the Study
There are several factors in addition to co-op status that could have had an effect on the students' academic achievement. These factors include: marital status, non-relevant co-op work experience, age when accepted into the building science program, maturation, co-op students studying with nonco-op students, and prior construction work experience. Also, the co-op students did not begin the treatment (co-op participation) at the same time that they were accepted into the building science program. Finally, the knowledge gained during the students' co-op work experience may not have been directly relevant to the coursework content taught in the building science curriculum.
There is another limitation to this study that also needs to be mentioned. The general hypothesis of this study is that co-op work experience enables the students to grasp academic concepts in construction education faster and easier because they might have already experienced the concepts in professional practice. This work experience in turn affects the co-op student's academic achievement. However, this hypothesis implies that construction education mirrors industry practice and that there is a direct linkage between work activities in professional practice and classroom content. In fact, it may be that educators are not teaching what the construction companies actually do in professional management to stay profitable in a fast-paced, changing, and risky business environment.
Co-op participation did have a significant effect on some co-op students' academic achievement in the five project management classes. Based on the results of this study, should the Auburn University building science faculty require mandatory co-op participation for students in the building science curriculum? There are many factors to be considered by the faculty and administration before such a requirement is enacted. Even if the only consideration for change is the potential for increased academic achievement among all building science students, the evidence from this study does not support such a drastic curriculum change.
Requiring construction management work experience as a mandatory part of the curriculum is an important issue facing not only the building science faculty at Auburn University, but also construction faculty and project management faculty at other universities. Hopefully the results of this study can be used in curriculum planning and administration decisions among other academic programs throughout the United States.
