Welcome to Chem21Labs where 21^st Century technology enhances student learning and reduces time spent on grading.

Chem21 is a pioneer in new technologies beginning with a Knowledge-based Learning strategy found in our patented TRQs, Timed / Repetitive Quizzes (an online Flash Card system that can be ASSIGNED). Students without knowledge in a particular area are incapable of critical thought - TRQs create and build knowledge!. After basic knowledge has been attained, Chem21 homework assignments challenge students to apply the TRQ knowledge at higher orders of critical thought.

Finally, Chem21Labs is a lab-submission program that guides student through the submission of lab data and answers. Chem21Labs grades the student's answers as they are submitted - instant feedback is the key to learning. Web reports that contain unknown information or other student results can be generated from student lab data - points for student results are awarded from this web page. The Chem21Labs program has a Flash-based graphing application and drawing palatte. The online environment makes it impossible for a student (or TA) to "lose" a lab report or for a TA to "leave" the university with ungraded student lab reports. It also standardizes grading among different lab sections since most of the grading is performed by the computer and the TA graded sections of the lab report can be viewed by the Lab Instructor for up to two years.
