ENGR – 2001  Introduction to Engineering Materials

Credit Hours:

3 (3-0)

Pre-requisite:

ENGR 1103 - Principles of Engineering Analysis and Design

CHEM 1211K - General Chemistry I

Catalogue Description:

Primary objective of this course is to introduce students to the study of engineering materials. Building on an understanding of atomic structure and chemical bonding from the knowledge acquired in GeneralChemistry, students should understand the chemical and size-factors which determines the way in which atoms pack together in solid materials. They should then be able to relate this to the observed mechanical, electrical, thermal, magnetic and chemical properties of those materials. Students will be introduced to material selection and processing as part of engineering design

Attendance Policy:

Class attendance at Albany State University is compulsory. Students' grades are based on daily class participation and performance. Professors will not administer examinations and quizzes to students who have been absent from class for reasons other than official business of the University, sickness, emergencies such as death in the immediate family (parents, grandparents, siblings, children), jury duty, court summons, etc. When students are absent for emergency reasons, the number of excused absences  permitted should not exceed the number of credit hours awarded for the course except for the most extreme unavoidable emergencies (e.g., death of immediate family members, jury duty, etc.). The instructor will officially certify all excused absences. Students will be responsible for the material covered in the class during his/her absence (excused or unexcused) and the home work assigned during the missed classes. 

If a student enters the class late (within the first five minutes after the class starting time) he/she will receive a tardy for that respective class.  Five tardies will constitute one absence.  If a student enters the class beyond the first five minutes or leaves the class early, he/she will receive an absence for that class meeting.  Should a student’s late entry into a class disrupt the learning environment, he/she will be asked to leave without discussion.

A student must not be absent from mid-term or final exams.  Under extenuating circumstances, such as the death of an immediate family member, serious personal illness or required jury/military duty, the instructor may allow a student to make up a missed mid-term or final exam.  The student should make arrangements with the course instructor prior to the scheduled date of exam if possible in order to be accommodated for makeup exam. Alternatively, students must inform the instructor at the earliest upon his/her return in order to qualify for the make up examination and must not wait till the end of semester.

Student must make up missed labs or exams, due to excused absences, within 5 school days. No request will be considered beyond that time.

Sanctions:

·        A score of ‘zero’ will be recorded for work missed due to unexcused absences including any tests.

·        If unexcused absences are above the number of credit hours for the course, course grade will be reduced by one letter grade (Exceptions: death of an immediate family member, Court appearance or Jury duty, personal illness. Must be verifiable with supporting documents.)

Academic dishonesty includes, but is not limited to: cheating, plagiarism and fraud.

a. Definition of cheating: The intentional misrepresentation of one’s work to deceive for personal gain, when in fact said work is not that person’s or assisting another to do the same, using information or devices that are not allowed by the faculty, obtaining and/or using unauthorized materials; fabricating information, research and/or results; violating procedures prescribed to protect the integrity of an assignment, test or other evaluation; collaborating with others on assignments without the faculty's consent; cooperating with and/or helping another student to cheat; unauthorized possession of exams and other related materials, intentional falsification of information on class assignments or presentations, demonstrating any other forms of dishonest behavior, using cell phone or sharing calculator during test or quiz.

Sanctions:

·     First Offense – a ‘zero’ for the activity that will not be dropped in tabulation of final grade.

·     Second Offense - an “F” in the course with a report of misconduct to the university for possible dismissal.

b. Definition of Plagiarism: Directly quoting the words of others without using quotation marks or indented format to identify them; using sources of information (published or unpublished) without identifying them; paraphrasing materials or ideas without identifying the source; unacknowledged use of materials prepared by another person or agency engaged in the selling of term papers or other academic material.

Sanctions:

·     Less serious forms of plagiarism which include improperly documenting quotations or not identifying sources will result in 10% grade reduction in the assignment.

·     More serious forms of plagiarism include submission of other’s work including another student’s, as your own will result in zero for the assignment on first offense and ‘F’ in the course for second offense with a report of misconduct to the university for possible dismissal.

c. Definition of fraud: Knowingly furnishing false information to the University and forgery, alteration, or misuse of miscellaneous documents, equipment (including computers),   records or identification.

Sanctions :

·     First Offense – a ‘zero’ for the activity in tabulation of final grade and official report of misconduct to Student Affairs

·     Second Offense - an “F” in the course and official report of misconduct to Student Affairs.

·     Third Offense - Removal from the course

Class Cancellation Policy:

If the class needs to be canceled, the instructor will notify students in advance and will assign numerical problems to be worked on or research reports to be prepared during the class period.

University Writing Requirement:

Writing is integral part of teaching and learning in all disciplines. Writing activities such as class project, lab report, test and quiz in this course may be evaluated for correct grammar and spelling. All handwritten statements have to be legible. Points may be taken off for grammatically incorrect statements or bad handwriting.
