The testbanks may be global that is, accessible to all classes or private only available to the one class. Here are some of my personal experiences with publisher systems. The class itself was taught in the classroom, not online. It has a lot of nice features, including videos and links to computer algebra systems for further exploration. The set-up is fairly complicated, since we have to integrate several computer systems. I don’t like that. They are all basically the same and can use the same test banks.
These were plain web sites with online assignments in eGrade. Keep in mind that these systems are constantly evolving. They still have problems with accepting alternative forms of the answers. Cheryl Doolittle reports that in one of her assignments, which had a correct answer of “sin x cos x”, the answer “cos x sin x” was counted as wrong. I found it impossible to assign specific topics to students. These courses are showing their age, and we are looking into modernizing them. It would be my first choice for self-study in mathematics at the high school or beginning college level.
I started out using the WebCT grade book, but was not sufficient for two reasons:. The major publishers are trying to get in on the act. A course coordinator is responsible for each large section, the TAs each take several small sections.
Professor Wagner left ISU around The equation editor has some counter-intuitive behavior, but this is supposed to get fixed by June We split the course into large sections of about to students each, and each of those eerver smaller sections of Scripts on the web site let them change study groups, ehrade and submit Excel homeworks, and other things. Typically the entire text of the textbook is available online in PDF form, sfrver with hot links: The products may have improved, or new features may have been added.
In Summer ofthe department had further budget cuts, and unfortunately had to let her go, as one of the two people with the least amount of seniority. Practice, homework, and proctored types have a defined passing score fgrade homework and proctored types homewori have a time limit. The problem sets have not been changed in many years, and we have received some student complaints about these courses recently.
She ran into some problems with MathXL that have not been resolved yet. Before you settle on a system, you should try out a number of sample problems.
We have refined some of the details over time and added features, and everything runs very smoothly know, but it still requires a knowledgeable person to troubleshoot. Unfortunately, I could not get it to work in this setting. A link from a homework problem will take you to the relevant section in the book. The only potential sedver comes from textbook publishers, who are trying to get into the market.
Each question may have a defined solutioncomment which is displayed to the student egrare of the solution if it is definedhint or hintswhich are only used for tutorial assignments, sserver detailed solutionwhich is only used for tutorial assignments.
These courses are showing their age, and we are looking into modernizing them.
If none are allowed, the assignment is not available. ALEKS has its own ideas of what a student should study next, and it refuses to budge. CourseCompass does not have these restrictions, only MathXL.

Their products combine examples, tutorials, and tests into one program, and the tutorials are quite good. Right now, these courses are not being taught in online form. MathZone is the McGraw-Hill product. In addition to being able to create testbanks through the Web interface, there is a Perl script provided with eGrade that converts egradf formatted LaTeX files into eGrade testbanks.
This can be used for tutorials, homework problems or tests. The students could take the quiz several times to improve their scores.
These were plain web sites with online assignments in eGrade. ALEKS assesses each student’s knowledge and decides which blocks the student need to study next, and in which order. Thus each time an assignment is done there will be a problem or problems from each of the topics, but the problems themselves will be different.
MathXL has the most stable and uniform interface of the systems I tried. Setver into WebCT starts the clock, and visiting the “My Scores” link at the end of the hour records attendance automatically.
All systems let you build homeworks and quizzes from problem testbanks. I said the answer was “2 sqrt 17 “.
