Academic & Social Impacts of White Boarding in a General Botany Course Martin Kelly (Biology), Daniel MacIsaac (Physics), & Kathleen Falconer (Elementary Education & Reading) DATA & ANALYSIS RESEARCH BACKGROUND Group learning is a critical component of teaching and learning about science. white boarding is a student centered, cooperative learning, instructional technique that can be incorporated into larger lecture based classes to foster an atmosphere where ideas are student-generated, and students construct their own evidence-based knowledge. From the collected final exams, the performance of each graded question was recorded. A statistical comparison (paired t-test) of the academic characteristics of General Botany (Lecture & White Boarding) was made to a previous General Botany course that only experienced lecture. While known in physics classrooms, we present the results of the 1st application of white boarding to a college biology course. We characterize the use of white boards to supplement the traditional lecture approach in General Botany. We describe the benefits of this instructional method in an introductory biology course. Lastly, linear regression was used to estimate the relationship between student performance (female and male) on the final exam with the number of points earned over the semester through white boarding. Relation between Final Exam & White Boarding (Female Students) Relation between Final Exam & White Boarding (Male Students) 180 200 WHY WHITE BOARD? white boards facilitate discussion in small groups of 3-4 students. At the beginning of a unit of learning, this establishes students’ prior knowledge. After an experiment, or set of lectures, white boards can help students draw more reliable conclusions. As an assessment tool, white boards give the professor an opportunity to see and hear students explain their thinking.

The comprehensive final exam had three sections. 1. The 1st section presented 7 terms for the students to define. 2. The 2nd section offered 3 concepts for the students to explain. 3. The 3rd section was a 4-part question that students answered in essay form. 140 SUMMARY OF DATA ANALYSIS * p<0.05 white boarding was investigated for its academic impact in a General Botany lecture (BIO 115, Fall 2003). Both courses (Fall 2003 vs. Fall 2001) were taught by the same instructor using the same textbook following the same order of topics in lecture and laboratory using the same point distribution was for each graded component of the course 160 40 67.4 •While known in physics classrooms, we present the results of the 1st application of white boarding to a college biology course. •We report and characterize the use of white boards to supplement the traditional lecture approach. •We compare the use and benefits of this method in biology and physics. There are two broad areas of questions being answered 1. Did white boarding affect the academic performance of students (Fall 2003 vs. Fall 2001)? 2. Did students benefit most from this student centered, cooperative learning, teaching technique? 160 40 WHY IS THIS TEACHING EXPERIMENT IMPORTANT? THE EXPERIMENT 180 Final Exam (total points) •The white board is a 24”x 32” dry-erase board. •In General Botany, each group used a large white board to record their thinking in response to the instructor’s POINT SOURCES concept directed question. •While white boarding, students shared their thinking with each other and came to a consensus solution in response to the instructor’s question or sample problem. Exam 1 (100 Points) Final Exam (total points) WHAT IS A WHITE BOARD & HOW IS IT USED? 8 summary measures of student academic performance were collected from each component of the course, Lecture & Laboratory. Final Exam Definitions (subtotal) Concepts (subtotal) Long Answer (subtotal) Exam (total) ARE THERE DIFFERENCES IN AVERAGE PERFORMANCE? Female Students & Male Students YES (p < 0.0931) NO NO NO The Fall 2001 class of General Botany differed significantly from the Fall 2003 class. •Differences were observed in terms of class composition (Freshmen, Sophomores, …, & other). •Students in the Fall 2001 course on General Botany had higher average grades on the Final Exam, on laboratory notebooks, and in laboratory participation. •Students in the Fall 2003 course on General Botany had a higher average grade on the 2nd lecture exam. On the comprehensive Final Exam, students from the 2001 General Botany class scored higher, on average, on the 1st part (Definitions) and 2nd part (Concepts) of the exam. However, there was a reversal in expected student performance on the 3rd part (Essay) of the final exam. The essay stresses the kinds of critical thinking and analysis skills developed through white boarding. Here, students from the Fall 2003 course on General Botany achieved a higher score, on average. There were no statistical differences between the number of female and males students enrolled in General Botany (Fall 2001 vs. Fall 2003). In addition, there were no differences in the average scores achieved by female and male students on the 2nd lecture exam or the final lecture exam. CONCLUSIONS Definitions (subtotal) YES (p < 0.0001) Concepts (subtotal) YES (p < 0.0001) Long Answer (subtotal) NO Exam (total) YES (p < 0.0001) In General Botany, female students realized real and significant gains on the final exam through knowledge and experience gained through white boarding Regression Analysis revealed that female students gained 2.5x more points on the final exam for every point earned through white boarding than did male students In 2003, white boarding resulted in equivalent academic performance of Female students with Male students in General Botany This result replicates findings from introductory college physics where white boarding was shown to result in equivalent performance on standardized conceptual achievement instruments This study supports the use of white boarding in college science lecture courses which have traditionally demonstrated gender-based gaps in academic performance REFERENCES Falconer, K.A. & DeGioia-Eastwood, K.
