General Education Student Learning Outcomes

 

Upon completion of this course, students will demonstrate competence in:

  • Critical Thinking

Gathering, analyzing, synthesizing, evaluating and applying information.

  • Interpersonal Skills

Interacting collaboratively to achieve common goals.

  • Quantitative and Empirical Reasoning

Applying mathematical, logical and scientific principles and methods.

  • Technology Skills

Using appropriate technology to retrieve, manage, analyze, and present information.

  • Written, Oral and Visual Communication
    Communicating effectively, adapting to purpose, structure, audience, and medium.

Concealed Handgun Policy

  • The Austin Community College District concealed handgun policy ensures compliance with Section 411.2031 of the Texas Government Code (also known as the Campus Carry Law), while maintaining ACC’s commitment to provide a safe environment for its students, faculty, staff, and visitors.
  • Beginning August 1, 2017, individuals who are licensed to carry (LTC) may do so on campus premises except in locations and at activities prohibited by state or federal law, or the college’s concealed handgun policy.
  • It is the responsibility of license holders to conceal their handguns at all times. Persons who see a handgun on campus are asked to contact the ACC Police Department by dialing 222 from a campus phone or 512-223-7999.

COURSE POLICIES

Attendance/Class Participation 

Regular and punctual class and laboratory attendance is expected of all students. If attendance or compliance with other course policies is unsatisfactory, the instructor may withdraw students from the class.

Withdrawal Policy:

It is the responsibility of each student to ensure that his or her name is removed from the roll should he or she decides to withdraw from the class. The instructor does, however, reserve the right to drop a student should he or she feel it is necessary. If a student decides to withdraw, he or she should also verify that the withdrawal is submitted before the Final Withdrawal Date. The student is also strongly encouraged to retain their copy of the withdrawal form for their records. Students who enroll for the third or subsequent time in a course taken since Fall, 2002, may be charged a higher tuition rate, for that course. State law permits students to withdraw from no more than six courses during their entire undergraduate career at Texas public colleges or universities. With certain exceptions, all course withdrawals automatically count towards this limit. Details regarding this policy can be found in the ACC college catalog.

 

The lecture and the lab are required in each chemistry course. If a student drops/withdraws from one section of the course, they must drop/withdraw from the corequisite.
 

 

THE LAST DAY TO DROP THE CLASS IS APRIL 27, 2026.

 I DO NOT DROP ANY STUDENT. IT IS YOUR RESPONSIBILITY TO WITHDRAW FROM CLASS!

MAKE-UP LABS.

There are no Lab make-ups; the lowest Lab grade will be dropped at the end of the semester. You can therefore miss only one Lab without penalties. The missed Lab will be the one to be dropped at the end of the semester.

In situations where Lab reports are not turned in on the same day of the Lab experiment, you will be given one week to turn in your work. Any Lab report turned in late will attract penalties. Lab report turned in one week late will get 10% of the total possible points off the grade score. Two weeks late will result in 20% off and so on.

 

 

Incompletes:

 An instructor may award a grade of “I” (Incomplete) if a student was unable to complete all of the objectives for the passing grade in a course due to medical/emergency reasons.  Students must have successfully completed at least 60% of the course materials to get an incomplete. An incomplete grade cannot be carried beyond the established date in the following semester. The completion date is determined by the instructor but may not be later than the final deadline for withdrawal in the subsequent semester.

 

Statement on Scholastic Dishonesty: 

 

A student attending ACC assumes responsibility for conduct compatible with the mission of the college as an educational institution. Students have the responsibility to submit coursework that is the result of their own thought, research, or self-expression. Students must follow all instructions given by faculty or designated college representatives when taking examinations, placement assessments, tests, quizzes, and evaluations. Actions constituting scholastic dishonesty include, but are not limited to, plagiarism, cheating, fabrication, collusion, and falsifying documents. Penalties for scholastic dishonesty will depend upon the nature of the violation and may range from lowering a grade on one assignment to an “F” in the course and/or expulsion from the college.

See the Student Standards of Conduct and Disciplinary Process.

 

 

 

Student Rights and Responsibilities:

 

 Students at the college have the rights accorded by the U.S. Constitution to freedom of speech, peaceful assembly, petition, and association. These rights carry with them the responsibility to accord the same rights to others in the college community and not to interfere with or disrupt the educational process. Opportunity for students to examine and question pertinent data and assumptions of a given discipline, guided by the evidence of scholarly research, is appropriate in a learning environment. This concept is accompanied by an equally demanding concept of responsibility on the part of the student. As willing partners in learning, students must comply with college rules and procedures.

 

 

 

Statement on Students with Disabilities:

 

 Each ACC campus offers support services for students with documented disabilities. Students with disabilities who need classroom, academic or other accommodations must request them through the office of Student Accessibility Services (SAS). Students are encouraged to request accommodations when they register for courses or at least three weeks before the start of the semester, otherwise the provision of accommodations may be delayed. Students who have received approval for accommodations from SAS for this course must provide the instructor with the ‘Notice of Approved Accommodations’ from SAS before accommodations will be provided. Arrangements for academic accommodations can only be made after the instructor receives the ‘Notice of Approved Accommodations’ from the student. Students with approved accommodations are encouraged to submit the ‘Notice of Approved Accommodations’ to the instructor at the beginning of the semester because a reasonable amount of time may be needed to prepare and arrange for the accommodations. Additional information: about Student Accessibility Services.
