ChemVantage - General Chemistry
An Open Education Resource

Who we are

ChemVantage LLC was founded in 2010 to provide Open Education Resources for teaching and learning General Chemistry. The founder and chief software architect of ChemVantage is Chuck Wight, who has taught General Chemistry since 1984 at the University of Utah, Weber State University and now Salisbury University.

Subject material

The database is currently populated with about 5000 quiz, homework, exam and video quiz questions in General Chemistry.

Why we created this site

Chemistry and many other technical disciplines are taught from a problem-solving approach. Lots of practice is required to build a solid foundation of skills for using knowledge to solve scientific problems. We create web sites that provide immediate feedback so that students can learn problem-solving skills through repeated attempts without having to wait long periods of time for their assignments to be graded by human instructors.

Learning versus testing

Usually, web sites with dynamic content like this one are best used as learning tools, not assessment or testing tools. For this reason, we have configured the software to allow students to submit proposed solutions to the problems as often as they want, in order to improve their scores. The objective is for students to use the feedback to correct their errors prior to the deadline for the assignment.


The quizzes presented here are designed to encourage students to read and understand the textbook used for the course. The questions are based on material presented in most introductory General Chemistry textbooks. The question items have straighforward answers not requiring detailed calculations. Questions are presented in several different formats including multiple choice, true/false, checkbox, fill-in-the-blank, and numeric answers. Each quiz consists of 10 questions drawn at random from a database containing many more questions. In the process of taking several quizzes to improve their scores, students will likely encounter some questions repeated from earlier quizzes; however, it is unlikely that any two quizzes will contain exactly the same set of questions in the same order. By assigning quizzes to be completed prior to the lecture, instructors can be assured that their students have some exposure to the material. This allows for more discussion, dialog and engagement in the classroom, and it makes learning more fun (really!).

Video Lectures

A series of 10-minute video lectures on a variety of General Chemistry topics is avialable from the Home Page. The videos are designed to reinforce the main points presented in many textbooks. Instructors can create LTI video assignments in the LMS; many of the videos used in this way contain embedded quizzes, and these scores are returned to the LMS grade book. Videos that do not have embedded quizzes will award full credit for watching to the end.


The homework assignments are designed to give students practice in solving quantitative problems having numeric answers. Each student can download the assignment, work the problems and submit the answers online. Answers are judged to be correct if the solution agrees with the solution found in the database to within a specified tolerance (indicated for each problem). For many problems, answers must be expressed with the appropriate number of significant figures. The site informs students which answers are correct, so that they can rework incorrectly solved problems and resubmit the answers. Each problem is based on a template that draws parameters at random, so the correct answer is different for each student. This makes them suitable for collaboration and working in groups, because even though the group may work to find a correct algorithm for solving a problem, each student will have to use the algorithm to find the detailed solution to his or her own problem.

Practice Exams

Students can take timed practice exams that draw questions from any group of 3 or more topics. Each exam is designed to take 60 minutes or less to complete, and includes a selection of 10 quiz questions worth 2 points each, 5 of the easier homework problems at 10 points each, and 2 more challenging homework problems worth 15 points each. The scores on each exam are disaggregated by topic to reveal the student's areas of strength and weakness. Practice exams may be repeated as often as desired. Questions are drawn at random from the database, and the numeric questions are parameterized, making it extremely unlikely that a student will ever get two identical practice exams.

Teaching Assistants

An instructor may assign any LMS user to be a teaching assistant. This role is recognized by ChemVantage. Teaching assistants may view solutions to homework exercises to provide guidance to students on some of the more challenging problems.


Any instructor wishing to contribute question items for quiz or homework assignments may do this using the instructor tools accessible in the assignments. A ChemVantage editor will review and edit them for clarity. The copyrights to all question items at this site are owned entirely by ChemVantage LLC. The only way that we can keep costs low enough to offer free accounts to both students and instructors is to avoid paying royalties to textbook publishers.
