The Major in Biological and Chemical Sciences

 

Mission of the Major

The major in biological and chemical sciences provides students the opportunity and the guidance to build for themselves a foundation in the fundamental areas of biology, the study of life, and chemistry, the study of matter, with particular emphasis on the areas integrating biology and chemistry. Students engage in active learning as they apply the scientific method towards understanding the natural world. As such, students think critically and creatively in evaluating data as well as issues related to biology and chemistry in society, including ethical conflicts surrounding particular scientific theories, technologies, or applications, and are trained to write and speak effectively about science and scientific issues. The BCS major helps students to understand diversity in the practice of science, through highlighting the important contributions of women and minorities and recognizing cultural bias and societal perspectives. Students are prepared for a variety of careers as well as advanced study in graduate school or any of the health professions

Means of Assessment of Outcomes

 

Student artifacts will be collected throughout the 2007-2008 academic year by the faculty member teaching the targeted courses. Each faculty member will evaluate if the students learned what was expected. Percentages of how well the student answered/completed the activity will be calculated, and students will be considered proficient if 70% of the students demonstrated a passing grade on the assessed activity.

 

How Assessment Data will be utilized

 

The Biological and Chemical Sciences major will meet yearly – at the start of the fall semester – to discuss the assessment of the previous academic year and to create a plan for the current year. At this meeting we will discuss if our students met our assessment goals, and if not, how to improve student learning for the future. At the conclusion of this meeting we will create our assessment plan for the current year.

 

Plan for the 2007-2008 academic year: BCS will collect student work for the targeted courses, and each instructor will evaluate if our students are demonstrating learning. In this trial run of assessment, we are hoping to streamline how we actually do assessment of student learning. Next August we will meet to discuss our collected artifacts and make a plan for the future – what worked, and what didn’t?


Specific Course Objectives and Assessment Measures for Required Courses

 

 

The alignments with the overall BCS objectives are located at the end of each course objective in parentheses. Each course objective – with the exception of the Comprehensive Examination and BCS 301 and BCS 402 – has an assessment measure associated with it. For the Comprehensive Exam and BCS 301 and BCS 402, the assessment measures are located in the bulleted list below the list of specific course objectives. Artifacts of many of these are located in Stratton 315.

Biology Courses

 

BIOL 151L: Principles of Biology I – The Biology of Cells

 

1.  For each student to master enough of the basic information about the biology of the cell to build a "big picture" about how cells work. (1)

         

          See, for example, answer keys to Chem Quiz (Fall, 2005), Exam I (October 30, 2005), Exam II (October 28, 2005), Exam III (November 21-22, 2005), Final Exam (December 15, 2005 – Part I).

 

2.  For each student to experience the process of science – to ask a question, to design and conduct experiments, to analyze the data, to communicate the results both orally and in writing (2, 3a, 3c, 3e)

 

          See, for example, the instructions and grading keys for two major lab reports:

                    1) Oral and Written reports on “Independent Investigations on the Enzyme
                             Tyrosinase” and

                    2) a) Short oral and written reports on “The Alcohol Dehydrogenase Gene in
                             Drosophila” – see instructions on page 4 of the lab (“Lab 8”)

                              description

                        b) Written report – “Drosophila Lab Report” – on the genetic analysis of a

                              mutant

 

3. For each student to develop critical thinking and cooperative learning skills. (3b)

 

                    For “critical thinking,” see for example Genetics Problem Set – problems

                     and answer key;  also, see example of “clicker” thought question during

                    class time, and answer sheet from student responses

 

                    For “cooperative learning skills” see instructions for Oral report on

                    “Independent Investigations on the Enzyme Tyrosinase”; see instructions for

                    Oral report on “The Alcohol Dehydrogenase Gene in Drosophila” – page 4

 

4.  For each student to see the applications of the biology of the cell to the world around us, and to consider the ethical implications of related technology (3f, 5)

 

                    See, for example, description of Lab #1, Resource Packet, and Hand-In Sheet

                    – “Embryonic Stem Cells, Cloning, and the Law” –  an ethical analysis of a

                    bill passed by the US Congress, but vetoed by President Bush, on research

                    on human embryonic stem cells

 

                    See, for example, the description of the student debates on two case studies –

                    - whether or not “Intelligent Design” should be taught in the public schools

                    as part of science classes, and whether or not transgenic plants should be

                    planted on the outskirts of a small town

 

5.  For each student to sharpen the skills of learning how to learn, and to continue the process of life-long learning in biology (1, 2, 3b)

 

                    See, for example, description of Lab #1, Resource Packet, and Hand-In Sheet – “Embryonic Stem Cells, Cloning, and the Law” –  where students are directed to talk about the issue in this lab, to make diagrams to explain the techniques involved, to present the techniques to the class, and to write down their decisions whether to vote yes or no on the bill – all different ways of working on the information, with the hope that several of these (but not necessarily the same ones) will be particularly effective for every student)

 

 

 

BIOL 152L - Principles of Biology: The Biology of Organisms

 

1.      Understand science as a process and how it applies to the study of biology (1,2,3a-f,5)

·        In the Rapid Radish lab, students design and conduct an experiment to answer a simple question about plant growth

2.      Understand the importance of evolution to explain the diversity of organisms. (1,2,4,5)

1.      Continue to work on the goals from Chem 107L (1,2, 3a-f,5)

2.      Understand the dynamic and predictive properties of chemistry. (1,2,3a,3b,3c,3f)

 

            See, for example, Chem 108L Exam #1 (8 March 2007), questions 1, 2, 3, 4 & 5

 

 

 

CHEM 213L - Organic Chemistry I

Chemistry 213L is the first semester of a two-semester lecture and laboratory class.  The lecture portion of the class teaches students the fundamental concepts in organic chemistry. In the laboratory section students practice important techniques used in the organic chemistry lab.  A pre-requisite for the course is general chemistry (Chem108L), and students in the class are typically in their sophomore year.  This is a core class in the BCS major and is taken by students in all three major concentrations.

 

1.      Recognize how the structure of carbon based molecules can aid in predicting reactivity, including acid/base and nucleophile/electrophile chemistry.(1,3b,3c)

-          These are assessed on the in-class exams and quizzes.  I have given a specific example from one of the exams.  Questions 5 and 6 test the students’ knowledge of acids/bases as well as nucleophiles.

-          Relevant artifacts:

o       Chem213L final exam - Questions 5 and 6

o       Chem213L in-class exam #3 - Questions 8, 9, and 10

2.      Evaluate how organic chemistry plays a role in our lives and how it is all around us. (1,2,3c,3f,4,5)

-          I typically use case-studies and in-class exercises that the students work on in groups.  The exercises are not typically collected, but the worksheets the students are given illustrate how this objective is met.

-          Relevant artifacts:

o       Rubbers and Raincoats in-class exercise*

o       A Case-study: Thalidomide: The pros and cons*

3.      Become familiar with the techniques used by an organic chemist in the lab and learn how to keep a good lab notebook. (1,2,3a,3d,3f)

-          Keeping a good lab notebook is essential for scientists and the students’ ability to write in one is assessed by grading them.  Each laboratory exercise teaches the students a new technique in organic chemistry.

-          Relevant artifacts:

o       Chem213L Lab Notebook sheet and grading rubric

o       Week 1 – Introduction to Techniques in the Organic Chemistry Lab (technique: melting point) and example lab notebook

o       Week 2 – Fractional Distillation (technique: distillation) and example lab notebook*

o       Week 3 – Extraction and Crystallization of Benzoic Acid and Triphenylmethane (techniques: extraction, crystallization) and example lab notebook*

o       Week 4 and 5 – Extraction of Caffeine from Tea (techniques: extraction, sublimation, thin layer chromatography) and example lab notebook*

4.      Identify trends in mechanisms and reactivity to reduce the amount of memorization needed (1,2,3b).

-          There are a number of reactions that must be learned in organic chemistry.  To aid the students in recognizing trends, they must complete a reaction notebook.  This exercise highlights important trends in reactivity as well as reaction mechanisms.

-          Relevant artifacts:

o       List of topics/information needed in your notebook

o       Chem213L Student Reaction Notebook

5.      Work together to solve a problem that has not been previously encountered and present the information to the class. (3a,3b,3c,3e)

-          In their final lab project, students are given a new reaction that they have not previously seen in lab.  They are to use the skills developed previously in lab as well as the knowledge gained in class to work through the problem.  The information must be presented to the class.

-          Relevant artifacts included:

o       Chem213L Final Lab Project handout

o       Chem213L student grading rubric and presentation

o       Chem213L Acid catalyzed hydration of 1-hexene and student presentation

o       Chem213L Oxymercuration/reduction of 1-hexene and student lab notebook

o       Chem213L Free Radical Polymerization Reactions and student lab notebook

6.      Work through a series of organic transformations in the lab and in class (a multi-step reaction sequence). (1,2,3a,3c,3d)

-          These are assessed both in the lab and in-class on the exams, quizzes and in-class exercises.

-          Relevant artifacts:

o       Chem213L – in-class exercises*

o       Chem213L – Synthesis of Aspirin from Oil of Wintergreen*

7.      Apply knowledge of reactions learned in class to laboratory exercises. (1, 3a-c)

-          This is actually done in a number of the labs, but I will give a specific example.

-          Relevant artifacts:

o       Chem213L – Acid catalyzed hydration of 1-hexene and student lab notebook

 

 

CHEM 214L - Organic Chemistry II

Chemistry 214L is the second semester of a two-semester lecture and laboratory class.  The lecture portion of the class teaches students the fundamental concepts in organic chemistry. In the laboratory section students practice important techniques used in the organic chemistry lab and learn how to search the primary scientific literature.  A pre-requisite for the course is the first semester of organic chemistry (Chem213L), and students in the class are typically in their sophomore year.  This is a core class in the BCS major and is taken by students in all three major concentrations.

 

1.      Recognize how the structure of carbon based molecules can aid in predicting reactivity, including acid/base and nucleophile/electrophile chemistry.(1,3b,3c)

-          These are assessed on the in-class exams and quizzes.  I have given a specific example from one of the exams. 

-          Relevant artifacts:

o       Chem214L Final exam – question 1

2.      Evaluate how organic chemistry plays a role in our lives and how it is all around us. (1,2,3c,3f,4,5)

-          Here I show how handouts are used to relate information to students as well as how exams and labs are used to test the ability of the students’ ability to work through problems relevant to their lives.

-          Relevant artifacts:

o       Chem214L Final exam - Question 6

o       Chem214L – Multi-step synthesis of N-methyl prozac and student lab notebook*

o       Chem214L – Useful chemistry… making soap and student lab notebook*

3.      Become familiar with the techniques used by an organic chemist in the lab and learn how to keep a good lab notebook. (1,2,3a,3d,3f)

-          In order to illustrate some of the important spectrophotometric techniques used in organic chemistry, I have the supplement my lecture with in-class exercises that are completed as the lecture progresses.

-          Relevant artifacts:

o       Chem214L – 1H-NMR worksheets*

4.      Identify trends in mechanisms and reactivity to reduce the amount of memorization needed (1,2,3b).

-          There are a number of reactions that must be learned in organic chemistry.  To aid the students in recognizing trends, they must complete a reaction notebook.  This exercise highlights important trends in reactivity as well as reaction mechanisms.

-          Relevant artifacts:

o       Chem214L Student Reaction Notebook

5.      Work together to solve a problem that has not been previously encountered and present the information to the class. (3a,3b,3c,3e)

-          In their final lab project, students are given a new reaction that they have not previously seen in lab.  They are to use the skills developed previously in lab as well as the knowledge gained in class to work through the problem.  The information must be presented to the class.  They must also identify a viable alternative synthesis to the one they will be carrying out using the primary scientific literature.

-          Relevant artifacts included:

o       Chem214L Final Project - Presentation handout and grading rubric

o       Chem214L Student rubric and presentation (3-Step Preparation of Polystyrene from Ethylbenzene)

6.      Work through a series of organic transformations in the lab and in class (a multi-step reaction sequence). (1,2,3a,3c,3d)

-          These are assessed both in the lab and in-class on the exams, quizzes and in-class exercises.

-          Relevant artifacts:

o       Chem214L Final exam - Question 4

o       2-Step Semi-microscale Preparation of a Cinnamate Ester Analog instruction sheet and student lab notebook

7.      Apply knowledge of reactions learned in class to laboratory exercises. (1, 3a-c)

-          This is actually done in a number of the labs, but I will give a specific example of how the NMR lectures and worksheets are integrated into the labs.

-          Relevant artifacts:

o       Addition of I2 to 4-pentenoic acid – with a twist! and student lab notebook*

8.      Identify synthetic routes to complex molecules using reactions encountered in class. (1,2)

-          Assessing the students’ ability to do this is done using exams, quizzes and in-class exercises.  A few examples are given below:

o       Exam Question 10

o       Chapter 15 in-class exercise – Diels-Alder Reactions

o       Chapter 10 in-class exercise – Retrosynthesis

o       Electrophilic Aromatic Substitution in-class exercise

9.      Choose a problem to study in the lab and design methods using the primary scientific literature to solve the problem utilizing the scientific method. (1,2,3a-f)

-          The students are first given a worksheet describing how to examine the scientific literature.  Their ability to search and use the primary literature is done through the writing of a proposal, where they must use and properly cite references.

-          Relevant artifacts:

o       Chem214L library worksheet

o       Chem214L final project overview

o       Chem214L final project synthetic proposal

o       Chem214L – example of a final project (grading rubric and proposal) – Preparation of Polystyrene from Ethylbenzene
