Online Spaces

  • OpenLab: This website will be the online home for our class. The site contains important information about the course, and will be used in various ways throughout the semester.
  • WeBWorK:  Much of the homework for this class will be completed on the WeBWorK system.  You will be provided with more information in the first week of class. [This needs to be set up.]  To go to our class WeBWorK site click here.
  • Blackboard: This will work in parallel with OpenLab. Somethings are better with BlackBoard and some better with OpenLab.
    You will be submitting your assignments through BlackBoard.
    • On the Blackboard menu “Units”, the first item will be the Upload site.
    • In order to turn in an assignment, you need to scan, rename, and upload a PDF file. Multiple pages must be submitted in one file. 
    • All this can be done by using the Notes app if you have an iPhone! Alternatively: Download the CamScanner app. There is a free version that works quite well.

Class Etiquette & Netiquette

Our class is scheduled to meet in person. However, it may be necessary to meet online. Please adhere to the following rules when engaging in class online:

  • Have your microphone and camera turned off while the instructor is speaking.
  • Be ready to turn on your microphone in case your instructor asks you a question.
  • You are expected to attend class virtually as if you are in a regular classroom. This means paying attention, taking notes, working on the problems that are assigned, and asking questions should they arise.


Attendance will be taken. Latenesses and students leaving before the end of the class will be recorded. If these become excessive, the student may be asked to withdraw from the course. Students who participate in the session for less than 40 minutes will be marked absent. In order to do well, attendance is highly recommended. In addition, it is the student’s responsibility to keep up with the material from missed class.

Academic Integrity Policy

Your work MUST be your own. Use of online or smartphone math solvers is strictly prohibited. I know the types of solutions and work that these apps display, and I will consider it a serious offense if anyone is suspected of using these apps, websites, or programs. Any one suspected to be in violation of this policy will be dealt with by the Academic Integrity Committee.

Students and all others who work with information, ideas, texts, images, music, inventions and other intellectual property owe their audience and sources accuracy and honesty in using, crediting and citation of sources. As a community of intellectual and professional workers, the college recognizes its responsibility for providing instruction in information literacy and academic integrity, offering models of good practice, and responding vigilantly and appropriately to infractions of academic integrity. Accordingly, academic dishonesty is prohibited in The City University of New York and is punishable by penalties, including failing grades, suspension and expulsion. More information about the College’s policy on Academic Integrity may be found in the College Catalog
