The Traditional Course
General Biology, a two-semester introductory course, is required of all students majoring in biology, psychology, neuroscience, biochemistry, and allied health. Approximately 260 students enroll in the course annually, 15% of the typical first-year class. Almost one-tenth of all students major in biology, the second largest major at the university. The university offers four lecture sections of about 35 to 40 students in the fall term and three in the spring term. Each lecture section meets three times a week for 50 minutes. Seven lab sections of about 20 students are offered in the fall and six in the spring. Each lab section meets once a week for three hours. Four different faculty members teach the lecture sections, and five faculty members plus additional professional staff teach the labs.
In the traditional format, General Biology is taught in a lecture format using an historic approach, with all faculty using the same syllabus. In-class technology consists of an overhead projector and transparencies. Labs consist of a series of 12 modules, each of which is designed to be completed in the three-hour lab session. Students do "cookbook" type experiments in which they memorize information rather than apply specific scientific methodology to answer biological questions. Neither lectures nor labs use computer-based instructional materials or online databases, despite the integral use of computers in biological research today.
The traditional course faces a number of academic problems:
Faculty have started to address these problems through some initial redesign efforts: a course Web page with tutorials and links to biology Web sites, a textbook-related CD for homework assignments, and an investigative online laboratory. Students have found these tools useful, which suggests the need for further redesign.
The Redesigned Course
The prime objective of the course redesign is to use existing technology to foster active, inquiry-based student learning while reducing per-student costs. The new approach to General Biology will offer a more interactive and individualized learning environment to students, use faculty time more efficiently, and reduce costs associated with lab materials.
The learning goals for the redesigned course will require students to
In order to achieve these learning objectives, the General Biology syllabus will be redesigned around the BioQUEST software library, using inquiry-based instructional modules that focus on problem posing, problem solving, and peer collaboration. BioQUEST moves the syllabus away from lower-level cognitive skills (e.g., memorization) to higher-order thinking in a highly interactive learning environment.
In the large lecture sections, modules will be supplemented with other technologies (CDs, DVDs, Web resources). Lecture sessions themselves will be redesigned to support teams of students working at computer stations (iBooks), each connected to an instructor-controlled computer via wireless technology. Students will be expected to interact via computers, and they will be expected to peer-mentor each other during in-class discussions. By redesigning lectures to accommodate small group learning, multiple lecture sections can be consolidated from seven to one each semester, reducing faculty numbers by almost half. Faculty will use their time more efficiently, as the new lecture structure supports a division of teaching responsibilities so that each of the remaining faculty can teach from his/her area of expertise.
Labs will be redesigned to use online laboratory modules, reducing costs of lab materials and allowing for a broader range of examples and hypothesis testing. Students will also use iBooks in labs to conduct independent investigations using modern software packages and Web-based exercises, thus creating a dynamic, inquiry-based environment.
Lectures and labs in the redesigned course will foster active, inquiry-based learning. The redesign also fosters more personalized learning with the introduction of recitation periods. Students will be divided into smaller (35-student) breakout sessions that will provide a non-structured environment in which to ask questions. Faculty can assess student understanding and get feedback on the success of classroom activities through these smaller sessions. This additional interaction with students will be made possible by the time savings realized in the redesign.
