Biology BA/BS

Goal
Effectively Deliver A Core Curriculum
Students will be presented well designed classes to facilitate mastering of the materials identified as a core foundation in biology – Botany, Zoology and Cell Biology


Objective
Mastery Of Core Curriculum
Students will demonstrate a mastery of the core fields in biology: Botany, Zoology, Cell Biology, Microbiology, Genetics, Ecology and Evolution.


Indicator
Assessment Exam For Core Classes
All graduating seniors will take an exiting Biology Assessment Exam (BAE), written by the Biology Faculty.  We will analyze the BAE scores from the following areas: botany, zoology, cell biology, microbiology, genetics, evolution & ecology to evaluate whether students have a significant level of understanding of each of these fields. 


Criterion
BAE Analysis For Core Classes
All Biology majors will be expected to score significantly better than a failing grade in all core areas: botany, zoology, cell biology, microbiology, genetics, evolution and ecology.


Finding
BAE Analysis For Core Classes
Fifty (45%) graduating seniors took the Biology Assesment Exam.  On average, students scored significantly greater than a failing grade (based a chi-square test against randomized answer choices) in all core areas. (Fig. 1).  In general, questions with a high level of difficulty usually had a high frequency of incorrect answers.   Questions of intermediate or low difficulty had a range of few wrong answer choices or a high number of incorrect answer choices (Fig. 2). 


Action
Administer Exit Exam
All Graduating seniors will be contacted by email and asked to take a biology exit exam that will test their comprehension of material from the basic core classes in biological sciences

Objective
Understanding The Scientific Method And Develop Critical Thinking
Students will demonstrate an understanding of the general nature of scientific knowledge and how scientific knowledge is gained (the scientific method).  They also will be able to critically evaluate scientific data to draw informed conclusions.

Indicator
BAE Analysis
All graduating seniors will take the Biology Assessment Exam (BAE). We will use BAE exam scores from analytical questions to evaluate a student’s understanding of the scientific method and critical thinking.


Criterion
BAE Analysis
All Biology majors will be expected to score significantly better than failing on analytical questions related to the scientific method and critical thinking. 


Finding
BAE Results For Scientific Method And Critical Thinking
We examined the number of questions missed for questions that required critical thinking and graphical interpretation.  Both are seated within principles of the scientific method.  We found a difference between questiosn requiring graphical interpretation; and questions not requiring interpretation of graphical data.  Specifically, students  missed more questions that required interpretation of graphs.  We found no difference between questions requiring analytical calculation and those not requiring calculations.  See Fig. 3 for Specifics.

Action
Administer Exit Exam
All Graduating seniors will be contacted by email and asked to take a biology exit exam that will test their ability to use the scientific method and think critically.


Update to previous cycle's plan for continuous improvement

Based on 3 years of assessment data, students tend to score similarly year after year.   Therefore, we will discuss these results in the department to evaluate whether core objective are being taught in all core classes.   We will investigate ways to increase retention of core material and promote critical thinking.


Plan for continuous improvement The departmental will continue to evaluate: 
 1. expections in each core area.
2. review questions within each core area
3. balance the number of factual knowledge questions and critical thinking questions.
4. create a broader range of question difficulties that will aid in analysis.
5. plan a mechanism to increase test turnout.
