COURSE DESCRIPTION:

 

Welcome to Clinical Immunology! This course is designed to meet the requirements of the National Accrediting Agency for Clinical Laboratory Sciences (NAACLS) for basic immunology and clinical immunology (including serological techniques).  The course will provide you with a basic knowledge of the principles of immunology, the application of these principles to diagnostic immunology, and exposure to current developments in the field. 

This class syllabus is a valuable resource; it provides useful information; acts as a study guide and will familiarize you with the pace of the course. Read it carefully and have it available for use at all times!  For your convenience the syllabus is available on Blackboard 5.0

 

It is your responsibility to become familiar with all aspects of this document.  Please review the course outline and objectives for each lecture, note the dates and times of examinations, and plan your study schedule accordingly. The course is designed to motivate students to become actively involved in the learning process.  This should enable the student to improve their comprehension, analyze and synthesize information, apply the information to clinical situations, and perform better on examinations (Metzler and Palau 1996).


 

A: Active Learning Strategies

 Listed below are some recommendations which should help you to be successful in this class:

 

·               Prior to attending class students should review and outline the assigned reading with special attention to:

- Chapter title

- Learning objectives

- Chapter introduction

- Italicized terms and abbreviations

- Headings and subheadings

- Illustrations, charts, tables, graphs

- End of chapter summaries

- End of chapter questions

 

·             Apply the stages of active learning/critical thinking listed below (this will help you to comprehend and retain information).

 

1. Think about what you already know about the topic you are studying

2. Decide what you need to learn (what you don't know); these are your learning issues

3. Formulate preview questions, based on your learning issues, which will allow you to                                   interpret, apply and evaluate the information you have read

4. Devise a means to alert yourself when you do not understand information you read  or hear in class

5. Devise a method for improving your comprehension

 

Attendance

Punctuality and regular class attendance are required. You are to sign the daily attendance sheet at the beginning of each class period.  The attendance sheets will be closed ten minutes after class begins.   There will be no make-up laboratory sessions, unless the student presents a documented excuse (medical certificate etc.).  A grade of zero (0%) will be earned for each missed laboratory session. Assignment due dates and examination dates published in the syllabus are NOT subject to change.

 

Examinations

There will be two in class examinations and a final comprehensive examination. These exams will include multiple choice, essay, and short answer questions.  Students who miss an exam will be allowed to take the exam at a later date if prior arrangements are made with the professor.

 

B: Writing Across The Curriculum (WAC)  

 

Clinical Immunology 709 is a writing intensive course which fulfills the third writing requirement for the Department of Clinical Laboratory Sciences.

 

Prerequisites: All students enrolled in this course must have earned a passing grade in ENGL-003.

 

Objectives:  The purpose of a writing intensive course is two-fold.  It is designed to improve the students’ writing ability, especially their professional writing (learning to write), and to improve the students critical, analytical, and problem solving skills (writing to learn). 

The writing components of Clinical Immunology will consist of pre-writing strategies (Journals, outlines, summaries), laboratory notebooks, and a formal case report on an assigned immunological disorder.  In these exercises there will be various stages of drafting and review (including peer-review).  Writing assignments will be evaluated based on organization, clarity of expression, grammar and spelling, as well as a clear understanding of the immunological concepts taught in the class.  Be sure to read the statement on plagiarism included on page 7 of this syllabus.

 

 

 WAC Components for CLLS-709.

 

A. Journals (15 %):

Each student is required to keep a bound notebook (loose-leaf papers will NOT be accepted) in which entries will be made in journal format.  This will enable you to be as creative as you like but your ideas must be organized in a coherent fashion and must be based on the course material. 

 

·                     It is suggested that each entry in the Journal notebook be a minimum of one (1) handwritten page, with a maximum of two (2) pages.  Occasionally journal entries will be made in class or submitted by e-mail. 

 

·                     There will be regularly assigned topics which will include summaries of class concepts, analogies of your choice to describe a particular concept to a specified audience (lay person, school children, and scientific community) and abstracts.

 

·                     You may make relevant comments on class discussions, your assessment of the strengths and weaknesses of the class presentations, and comments as well as questions on the subject matter.

 

·                     You are required to reserve the first three pages of your journal notebook for a glossary of new Immunology vocabulary terms, definitions, and phrases.

 

·                     All entries must be dated and given a title.  Entries that are not legible, dated, and titled will not receive a grade unless revised and resubmitted when the notebooks are next collected. 

 

·                     Journals will be collected on Monday and will be returned to you on Wednesday of each week.

 

·                     If you are reading this e-mail me now at mneita@howard.edu for an additional 3 points on your first exam (This offer is valid until 10.00 am August 25, 2004).

 

Since you are expected to keep abreast of current developments in the field of immunology, each student is required to submit summaries for three (3) current, full length articles in immunology from peer reviewed journals (written & electronic).  Copies of the original articles are to be submitted with the summary, which must be written in language a lay person can understand (Appendix A).  This will constitute 30% of the JOURNAL grade.  These summaries are due on the following dates:

 

September    20

October        18

November    15

 

Late summaries will not be accepted without prior discussion with, and approval of the professor.


 

JOURNAL GRADING:

JOURNALS will be graded from a holistic perspective. Your writing will be evaluated on the basis of a general impression of the content, arrangement and style.  Grades will be as follows:

 

A                     (15 points) outstanding

B                     (10 points) good

C                     (7.5 points) adequate

F                      (2.0 points) unsatisfactory

Entries which receive a Grade of F may be rewritten and resubmitted with the next journal entry for an upgrade (maximum upgrade is a B).

 

Laboratory Notebooks (15 %):

You will be required to keep a laboratory notebook.  Sections 1-3 below must be done as a pre-lab write-up before each laboratory session.  Entries for sections 4-5 below are to be made during the laboratory exercise and should include any calculations made, comments on technical errors, observations, and results.

Details of the Laboratory Write-up:

The record of the laboratory procedures must be completed in a clear, concise and accurate manner. Students should minimize the use of personal pronouns (I, we).  All entries should be made in the passive voice. 

E.g. incorrect: I pipetted 1 ml of reagent into each tube

      Correct:  1 ml of reagent was pipetted into each tube

 

Do not use white-out or erasers to remove errors from your notebook, instead draw a line through the error and make your correction next to it. The detail in the laboratory write-up should be sufficient to allow a fellow student to use your notebook as a guide. Laboratory notebooks will be evaluated based on completeness, adherence to the format, organization and understanding of the exercise. (If you are reading this, e-mail me now for 3 Free Points!)

 

The outline for each laboratory write-up is as follows:

 

1.   Introduction and Theory.   This section will include a three- or four- sentence statement of the objective of the laboratory exercise.  A brief discussion of the theory and principles of the methods used should follow this.  A description of the techniques, instrumentation and chemical or biochemical reactions should be included.

 

2.   Materials and Supplies.  A complete list of all materials, reagents and equipment is to be provided.  The sources and concentrations of all chemicals and solutions should be listed.  Instrumentation is to be listed with reference to company name and model number.

 

3.   Procedure.  This section is to contain a flow chart to describe the procedure.  The procedural details and any observations are then recorded while the laboratory procedure is performed.  You should include all observations, such as color changes, that occur.  

 

4.   Results and Calculations. Results are to be recorded directly in your notebook, not on scraps of paper or paper towels.  Results may be recorded in a tabular form where appropriate.  Calculations and graphs where necessary, must be included.

 

5.   Conclusion and Discussion.  This section should contain a conclusion based on the laboratory results and a three- or four-sentence discussion of their clinical significance.  You should compare your results with known normal values for the procedure.  Outline any problems encountered during the procedure and comment on their effect on the results with recommendations for avoiding these in future laboratory exercises. Each laboratory session will have an accompanying  grading sheet  which must be completed and turned in at the end of the class ( Appendix B) .

STATEMENT OF PLAGIARISM

 

Plagiarism is the representation of another person’s word and ideas as your own.  This misrepresentation is a breach of ethics that seriously compromises a person’s reputation. Professional careers have been ruined by revelations of plagiarism.

 

Researchers, therefore, must scrupulously acknowledge sources to give proper credit for borrowed materials.  The following rules should be observed to make sure that the distinction between your own words and ideas and those of others is justly maintained.  Of course, submitting a paper that is completely the work of another person is plagiarism in its most extreme form.

 

1.   Words, phrases, and sentences of another person should be enclosed in quotation marks and cited in proper form.

 

2.   Paraphrases and summaries of the ideas of ideas of others should be properly cited.  These paraphrases and summaries should not represent merely the rearrangement of sentence elements but should be written in your own style.

 

 

3.   Quotations, paraphrases, and summaries should be introduced with the name of the writer being cited.

 

4.   Every item in the paper (i.e., all sources of others’ word and ideas) should appear in the bibliography in proper form. (If you are reading this e-mail mneita @ howard.edu for 2 free points! Offer valid until Saturday, September 4, 2004).

 

 

5.   Citations should contain all the information required by standard conventions and specifically indicate the location of the material cited.  Page numbers should be checked for accuracy before the paper is submitted; the reader must be able to find the source of the material quoted, paraphrased, or summarized. Forms for citations and bibliographies should conform to those indicated by the professor.

 

For a further discussion of plagiarism, read the pertinent sections in A Writer’s Reference, by Hacker.

 

If you plagiarize all or part of an assignment, you can expect severe penalties, ranging from failure in that assignment to being recommended for a hearing before a judiciary body of the University. For a list of penalties, which may be imposed, see The Student Code of Conduct and Judiciaries in the Student Reference Manual and Directory of Classes.

 

Students should be aware that any incident of plagiarism or other form of academic dishonesty in this class will be dealt with severely.
