Domain Name Com's - Software : ChemTutor Excalibur


  

Rating: 3 out of 5 stars - It could be better
I am a high school Chemistry teacher and I bought the ChemTutor Excalibur software hoping to use it as a review tool for my students. It has some good information, but I was very disappointed in the lack of animations or diagrams that would prove extremely useful in explaining chemical concepts. It is a fairly good review tool, but I am not sure it is worth the money.They could come up with a more interactive and interesting program especially for chemistry.



Rating: 5 out of 5 stars - ChemTutor® Excalibur is Excellent
I have been using ChemTutor® Excalibur for the past two years in each of the chemistry courses that I teach and I will be using it again this year. I have found it to be an excellent resource for students as they work their way through their study of chemistry. The interactive tutorials in ChemTutor® Excalibur are thorough, yet concise, and they do a great job of teaching students all of the concepts and calculational procedures that are covered in first-year and AP Chemistry. I encourage all of my students to use ChemTutor® Excalibur throughout the school year as they learn each unit of material, and at the end of the year as they prepare for their year-end exams. At the end of this past school year, 8 out of the 10 students in my AP Chem course earned a 5 on the College Board AP Chemistry Exam. My first-year students scored equally impressive results on the SAT II Subject Test in Chemistry with a lot of 700+ scores. I have to give a lot of the credit for these results to ChemTutor® Excalibur, which does an excellent job of helping students to prepare for these exams.

I encourage anyone who is interested in thoroughly learning chemistry to use this software. However, it is important for students to use ChemTutor® Excalibur as it was designed to be used. Students who use it as nothing more than a series of multiple choice practice tests are missing the important tutorial aspects of the program. There are LEARN buttons and EXPLANATION buttons that have to be clicked in order to get the full value of the software. ChemTutor® Excalibur teaches new concepts and procedures by way of example, which students appreciate; the software then has the students apply what they are learning, which is the best way to truly learn chemistry. For example, in working through the Chemical Reactions & Equations tutorial, a student will be asked whether an aqueous solution of ferric nitrate will react with magnesium or copper or neither or both. It is important for the student to then click on the LEARN button. This brings up a screen that teaches the concepts associated with single displacement reactions and the order of activity of metals, and gives the student an example using different reactants. The student can then apply this information as they try to answer the original question. They are given immediate feedback as to whether they have solved the problem correctly or not. The student can then click on the EXPLANATION button, which brings up a screen that explains in detail how to solve that specific problem. Later on in the tutorial, after learning about other types of reactions, the student will encounter additional single displacement problems with metals using different sets of reactants to help reinforce what they have learned about this type of reaction. The LEARN and EXPLANATION screens will still be available, if needed, but eventually the student will develop the confidence to solve each type of problem without referring to these screens.

When used in this way, ChemTutor® Excalibur is an awesome learning tool. With ChemTutor® Excalibur, students can learn chemistry on their own and at their own pace. Every chemistry student should have this software.

Rating: 2 out of 5 stars - Buyer beware...
In the product description and most of the reviews below, this software is presented as an interactive course and the Holy Grail for success in high school or introductory college chemistry. I made the mistake of ordering this software for my high school kids based on the product description and many of the 5-star reviews.

After I received the product from Amazon, I realized I should have paid more attention to a review posted by "marco" on July 4, 2004, who said: "I actually felt like a dupe for buying it". It also raised a question in my mind about the validity of the 5-star reviews, many of which have been posted in quick succession.

As pointed out by the previous review and also by "marco", ChemTutor assumes that you ALREADY know chemistry well. My opinion: ChemTutor is NOT a course, but a collection of multiple choice chemistry test questions with solutions, with the questions presented in random order of difficulty. One can get similar questions/solutions from the usual Chemistry test prep books, and most prep books also cover the basics. "ChemQuiz" might have been a more appropriate title for ChemTutor. I would have returned this product, but with opened software, that's not possible.

Unfortunately, even the ChemTutor software box says "A Complete Interactive Chemistry Course On CD", and has a quote printed on the back which says that with ChemTutor, "I could pretty much throw away my textbook".

This is probably the only instance in a few years of shopping on Amazon, where I felt misled by both the product description and "reviews". For that reason I feel compelled to post this, my first review on Amazon. For the misleading product description, I give this software a rating of 1 star; for the multiple choice questions, I give it 3 stars, resulting in an overall rating of 2 stars.



Rating: 4 out of 5 stars - To be honest with this product...
I have to say that if I were to give this product a rating for information, I would give it 5 stars. But it stops right there. My reasons:

1.) If you haven't taken an introductory course in chemistry or any similar class, this software will surprise you. First, (and this might really shock you) the software does not give you initial lessons or instructions; it will just start asking you questions specific to the topic you picked. It does, however, have an explanation section, which will give you a hint or a briefing on how to solve the problem in front of you. Although sometimes, the explanations are profound or incomplete. It assumes that you know basic chemistry jargon. There are words that you will think you know, but actually have extended or other meanings in chemistry. Second, the concept of the factor-label method or dimensional analysis, which is crucial to solving chemistry math problems, is never taught. Again, the software assumes you know that. Be sure you know it if you're going to buy this software.

2.) There is a bad question organization. No, I take that back, there isn't even a question organization. The questions come up randomly, not in a specific order, which means that sometimes you might get the hardest question in the beggining. This is a big problem if you do not have prior education on the subject. Obviously, you won't be able to do a hard question if you haven't encountered the basic ones, and this will just "oxidize" your patience.

3.) For a software so popular, you wouldn't expect to find low quality images. This seems that the software was done in such a rush--which leads me to another point: there are few noticeable spelling errors, which I think can change the way people spell. Moreover, it gives a bad impression to some users.

But enough of the bad talk, I said I would give it 5 stars for if it were only for information.



Rating: 5 out of 5 stars - I totally agree with Ms. Caroline Leach!
OH MY GOD! How did Interactive Learnings, Inc. come up with such a software! This is a work of genius, and I am grateful for ChemTutor Excalibur, because it has helped me so much for me to earn a A+ in my advanced chemistry course!To be honest, I am not a science guy, and I never was, until my friend suggested this great program, ChemTutor Excalibur. ChemTutor Excalibur has helped me to see a whole new world of chemistry. With Test Simulation mode, you can choose any part of chemistry that seems most challenging to you, and be tested on many different varieties of questions. In addition to that, with clear explanations for every single problems, even you can be a chemistry master in no time! If you want a A+ in your chemistry course, get ChemTutor Excalibur, NOW. You will not regret it, and I guarantee it. I LOVE CHEMTUTOR!
