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.

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 number of points earned by a male
student on the final exam was not
dependent on the number of points he had
earned through white boarding.

Lastly, the same comprehensive, final exam was given in both years.
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.

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

•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?

•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

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.

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.

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.

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
