A growing body of academic research supports the use of project-based learning in schools as a way to engage students, cut absenteeism, boost cooperative learning skills, and improve test scores. Those benefits are enhanced when technology is used in a meaningful way in the projects. Following are synopses of a range of studies on project-based learning:

British Math Study

A three-year 1997 study of two British secondary schools -- one that used open-ended projects and one that used more traditional, direct instruction -- found striking differences in understanding and standardized achievement data in mathematics.

The study, by Jo Boaler, now a professor of education at Stanford University, found that students at the project-based school did better than those at the more traditional school both on math problems requiring analytical or conceptual thought and on those considered rote, that is, those requiring memory of a rule or formula. Three times as many students at the project-based school received the top grade achievable on the national examination in math.

Challenge 2000

In a five-year study, researchers at SRI International found that technology-using students in Challenge 2000 Multimedia Project classrooms outperformed non-technology-using students in communication skills, teamwork, and problem solving. The Center for Learning in Technology researchers, led by Bill Penuel, found increased student engagement, greater responsibility for learning, increased peer collaboration skills, and greater achievement gains by students who had been labeled low achievers.

The project conducted a performance assessment designed to measure students' skills in constructing a presentation aimed at a particular audience. Students from Multimedia Project classrooms outperformed comparison classrooms in all three areas scored by researchers and teachers: student content, attention to audience, and design. The Multimedia Project involves completing one to four interdisciplinary multimedia projects a year that integrate real-world issues and practices.

Cognition and Technology Group

A 1992 study of 700 students from eleven school districts in Tennessee found that students doing projects using videotaped problems over a three-week period performed better in a number of academic areas later in the school year. The study, by the Cognition and Technology Group at Vanderbilt University, examined student competence in basic math, word problems, planning capabilities, attitudes, and teacher feedback. Students who had experience in the project work performed better in all categories.

A 1999 study by the Center for Research in Educational Policy at the University of Memphis and University of Tennessee at Knoxville found that students using the Co-nect program, which emphasizes project-based learning and technology, improved test scores in all subject areas over a two-year period on the Tennessee Value-Added Assessment System. The Co-nect schools outperformed control schools by 26 percent.

Does It Compute?

Analyzing data from the math portion of the 1996 National Assessment of Educational Progress test given to students nationwide, Educational Testing Services researcher Harold Wenglinsky found that the effectiveness of computers in the classroom depended on how they were used. In his report, Wenglinsky found that if computers were used for drill or practice, they typically had a negative effect on student achievement. If they were used with real-world applications, such as spreadsheets, or to simulate relationships or changing variables, student achievement increased. Data were drawn from the samples of 6,227 fourth graders and 7,146 eighth graders.

Expeditionary Learning Outward Bound

Three elementary schools in Dubuque, Iowa, showed significant test score gains after incorporating the Expeditionary Learning Outward Bound (ELOB) program. At ELOB schools, students conduct three-to-six-month-long studies of a single topic with an emphasis on learning by doing. After two years in the program, two of the three schools advanced from "well below average" to "well above the district average" on the Iowa Test of Basic Skills. One elementary school raised its average score from the 39th to the 80th percentile. After four years in the program, student scores were "above the district average in almost every area." Separate analyses showed similar test score gains in ELOB programs in Denver, Boston, and Portland, Maine.

Since 1996, Rockman et al., an independent research firm in San Francisco, California, has studied the impact of widespread use of laptop technology on teaching and learning. The focus of the firm's multiyear studies has been on dozens of public and private K-12 schools participating in a pilot laptop program sponsored jointly by the Microsoft and Toshiba corporations. Through both observation and feedback from laptop-using teachers and students, researchers have documented a shift from lectures and other teacher-centered forms of delivery to lessons that are more collaborative and project-oriented. Teachers, researchers note, become facilitators in project-oriented classrooms, with students increasingly assuming the role of directors of their own learning.

In a 1998 report, researchers note that three-fourths of the teachers who participated in a Rockman survey reported that project-based instruction had increased since the introduction of the laptops in their classrooms. Among the many reported benefits of this project-based approach to learning are greater student engagement, improved analytic abilities, and a greater likelihood to apply high-order thinking skills.

Laptop-using students also performed better on a Rockman-administered writing examination. The research firm did not, however, identify significant differences in the standardized test scores of laptop-using students. Researchers offered two possible explanations for the lack of significant improvement in this area: 1. Standardized tests are not designed to reflect the types of learning that laptops support. 2. Because the students had been using their laptops for less than two years, it might have been too soon to see noticeable gains in areas that are covered by standardized tests.

Successful School Restructuring

A five-year study by University of Wisconsin-Madison researchers found that structural school reform works only under certain conditions:

  1. Students must be engaged in activities that build on prior knowledge and allow them to apply that knowledge to new situations.
  2. Students must use disciplined inquiry.
  3. School activities must have value beyond school.

In their report, "Successful School Restructuring," the researchers at Wisconsin's Center on Organization and Restructuring of Schools found that even innovative school improvements, such as portfolio assessment and shared decision making, are less effective without accompanying meaningful student assignments based on deep inquiry. Researchers analyzed data from more than 1,500 elementary, middle, and high schools and conducted field studies in forty-four schools in sixteen states between 1990 and 1995.

Union City, New Jersey School District

The Center for Children and Technology at the Education Development Center, Inc., monitored a two-year technology trial that was first implemented in the district in September of 1993. The study found that after multimedia technology was used to support project-based learning, eighth graders in Union City, New Jersey, scored 27 percentage points higher than students from other urban and special needs school districts on statewide tests in reading, math, and writing achievement. The study also found a decrease in absenteeism and an increase in students transferring to the school. Four years earlier, the state had been considering a takeover because Union City failed in forty of fifty-two indicators of school effectiveness.

Modeling Instruction in high school physics includes projects, and it's an improvement on project-based instruction because students are guided to develop and use scientific models in order to do their real-world projects. Projects called lab practicums are culminating activities in each two-week modeling cycle. Students need scientific models to guide them in doing projects.

Here's an example: an email posted on Dec. 10, 2007 to the modeling listserv by a veteran teacher and advisor for the robotics club:
"... Modeling Instruction is far and away the most effective way to teach kids real science and math in the world today. The Briarwood Christian High School B.E.S.T. Robotics Team (Boosting Engineering, Science and Technology through Robotics) won first place in the SOUTH'S B.E.S.T. ROBOTICS TOURNAMENT at Auburn University on Saturday, Dec.8. This was a 48 team tournament from states East of the Mississippi River. They won a 24 team ALABAMA B.E.S.T. Robotics Tournament to get to the SOUTH'S B.E.S.T.
The only difference I can see in our kids and kids from other schools
(including engineering and magnet schools) is that our kids are being
taught science with the Modeling Instruction Method. They have the
"tools" to solve real problems. At the tournament they spent two days
without any adult advice and solved all of the problems on the robot
they designed and built throughout 16 rounds. My job was bus driving,
getting food and enjoying their success."

Reggio Emilia, Italy has been using project-based learning with children for over 30 years. The entire community is committed to the growth and development of its children through projects, viewing teachers as learners, documentation, and interactive classroom environments. Curriculum begins with teachers observing students interests and then introducing materials based on those interests. Students' learning occurs through playing, creating, questioning, and exploring activities centered around a particular theme (i.e. ocean animals, money, transportation, or mysteries).

The Compass School in Powell, Ohio is one such school utilizing the Reggio Emilia philosphy as are many others around the country. A community of learners is established as students work together to learn about their interests. Students are more engaged because they have taken an active role in developing the curriculum and are more likely to retain the knowledge because they have made connections to the real world.

Individuals who work with young children(ages 2-5) and who want to help caregivers and teachers promote the initiative of the child within the context of a rich play and learning environment, should explore the Pyramid Method of Early Learning from The Netherlands, developed by educational psychologist, Dr. Jef van Kuyk, from Cito in Arnhem. The approach incorporates the distancing theory of representational thought as well as dynamic systems theory, and includes an approach to using "projects" as a way to help children take an active part in learning. An initial pilot program in the United States is beginning in Atlanta.

Dear Edu Staff,

Re: PBL high schools-

1) what type of colleges/ universities do they attend? What about their SAT scores? Scholarship opportunities are mostly linked to good scores, GPA, etc... Is there any data on this?

2) Can an IB program be delivered by PBL?

Your article states that to view the results of the Brittish math study, you must only register with the Edweek site and that registration is free. I registered for the free level, but am told that I still cannot view the study unless I pay a $2.95 per article fee or a more expensive monthly subscription fee. The free registration is not enough.

Can anyone share what they have done with PBL with their Special Education students? How has PBL worked with students who are language delayed &/or cognitively challenged? Is there a place to find already created PBL lesson plans to see how these kinds of learning activities are fully developed?
Thank you.
