Learning Outcomes

By the completion of your biology courses at Oakton, you will have gained the experience to.....

  1. Think critically – identify, define, analyze, interpret, and evaluate ideas, concepts, information, problems, solutions, and consequences. This includes the ability to compute and comprehend quantitative information and to engage in the scientific process.
  2. Communicate – communicate ideas, concepts, and information through written and oral means. Collaborate with people of diverse backgrounds and abilities.
  3. Demonstrate literacy – demonstrate the ability to read critically within content areas. Use technology to locate, evaluate, and communicate data, information, ideas, and concepts. Assess, critique, and select from a variety of information resources.
  4. Demonstrate responsibility – demonstrate an understanding of personal responsibility and ethical behavior in one’s own academic and civic life.

V.    Academic Integrity and Student Conduct

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

Please review the Code of Academic Conduct and the Code of Student Conduct, both located online at
