<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">I've received a couple of questions about homework, both the<br>
MasteringChemistry on-line homework and the textbook “assignments”.<br>
I think all of you have been able to get into MC by now, although it<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><br>
As I've mentioned multiple times, we are doing on-line homework<br>
using MC. I'm trying to limit this so as not to overwhelm you.<br>
Overall this will contribute 7.5% of your course score. All the various<br>
types of problem sets are always available to work on, even past the<br>
due dates (although you won't get credit for anything done after the<br>
due dates). However, the on-line homework I'm giving is not enough.<br>
I discuss this below.<br>
<br>
After using various things in MC for the last couple of years I've come<br>
to some conclusions about what seemed to work best for most students<br>
based on what they stated during the course. Similar info can be found<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">in an e-mail with subject line “MasteringChemistry – Credit/Noncredit”.<o:p></o:p></span></p>

<br>
There are the tutorial problem sets which are <b><span style="color:red">for CREDIT</span></b>. I've tried to<br>
limit these to a reasonable number based on giving a broad enough<br>
sampling of problems. I don't want someone getting "stuck" in these<br>
and spending too much time. The tutorials provide hints but there is a<br>
minimal penalty of 2% for each hint. There's also a penalty of 3% for<br>
incorrect answers. This is to keep you from simply asking for hints or<br>
guessing until you get the right answer. The point values for the questions<br>
differ, from 1-3 pts depending on the difficulty (higher difficulty level<br>
is worth more points). Most students have told me the tutorial sets<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">are very useful.<br>

These will generally have names with the following format:<br>

b) <b><span style="color:red">Homework Review sets:</span></b><br>
<br>
There are homework review problems which are <b><span style="color:red">for CREDIT</span></b>. Again,<br>
I'll try to keep this to a reasonable number of questions.<br>
<br>
Some of these have hints or feedback but most don’t. That's determined<o:p></o:p></span></p>

These will generally have names with the following format:<br>

a) <span style="color:blue">Dynamic Study Modules (DSM) sets:</span><br>
<br>
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">These are </span>

</span></b><span style="font-family:"Arial",sans-serif">for credit. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><br>
There are the Dynamic Study Module (DSM) sets which are technically<br>
always available in MC but I will make some up specifically. To me they<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">seem to be easier than the end-of-chapter problems. Students stated<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">this to me as well. There were other things they stated about why they<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">didn't think these were as useful. I would do these after doing the book<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">problems and the for-credit MC problem sets, if you're still having<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">problems. Maybe if you didn't do well on the quiz you could do these to<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">help learn what you didn't know for the quiz. You could use them as part<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">of your review for the exams. These are at a lower level than the textbook<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">EOC problems. I spoke to the Pearson rep recently who said they’re<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">mostly intended to make sure you understand the bare minimum.<br>
<br>
There will be "due" dates, generally around the time I think you should<br>
be completely done with the material. The due dates mean nothing as<br>
you always have access to them and they're not for credit. I'm just<br>
trying to let you know when you should be done with that material.<br>
<br>
The names for these are set by MC but have "Dynamic Study Module"<br>
in the name. They changed these between autumn and this semester<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">which rendered all of the ones which were copied inoperable. I have to<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">redo them all. I will probably be changing the way these are presented<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">as by chapter as a review before midterms. That’s how they’ve set<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">them up for the future.<br>
<br>
b) <span style="color:blue"> Practice Exercise 1 sets:</span><br>
<br>
These are </span><b><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:red">NOT</span></b><span style="font-family:"Arial",sans-serif"> for credit.<br>
<br>
Within every chapter there are Sample Exercises. As I've explained<br>
elsewhere, you should make a valid attempt at doing these as you<br>
come to them while reading and analyzing a section. Then there are<br>
a couple of Practice Exercises following the Sample Exercise. Try<br>
PE2 since there's answers to those in the back of the book (in the<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">“Backmatter” after the answers to the Go Figure questions for a chapter).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">There are no answers in the book for PE1. PE1 is always multiple<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">choice but even if you got one of the answers that doesn't necessarily<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">mean you got the right answer.<br>
<br>
The PE1 questions are available in MC. I’ve made "practice" sets<br>
which contain the PE1 questions for each chapter. This will allow<br>
you to get the answers. This way, if you're trying to answer these PE1<br>
questions as you're reading along you will no longer have to worry<br>
about whether you did or didn't get them right. You can now pull up<br>
the PE1 set and find the answer. I reiterate, these are just for practice<br>
as you're reading through the sections. Those for Ch 13 and 14 are<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">up (although PE1 for Sample Exercise 13.6 is missing in MC).<br>
<br>
There will be "due" dates, generally around the time I think you should<br>
be completely done with the chapter. The due dates mean nothing as<br>
you always have access to them. I'm just trying to let you know when<br>
you should be done with all the reading and homework for a chapter.<br>
<br>
These will generally have names with the following format:<br>
<br>
Ch 13 Practice Exercise 1 or Ch 13 PE1<br>
<br>
These are </span><b><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:red">NOT</span></b><b><span style="font-family:"Arial",sans-serif;color:red">
</span></b><b><span style="font-family:"Arial",sans-serif">worth points</span></b><span style="font-family:"Arial",sans-serif">. Honestly, I think doing the Sample Ex.<br>
and PE 2, the homework from the book, the MC tutorials and the MC<br>
homework review sets (the latter two are for credit) should be enough.<br>
<br>
*********************<br>
<br>
The on-line homework is NOT a substitute for reading the textbook<br>
and critically analyzing the material. Included in this is doing<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">homework exercises more than once.<br>
<br>
I've "assigned" end-of-chapter (EOC) problems from the book <br>
which you will find on my class web page (not Carmen). You do<br>
not get credit for these. However, it is of utmost importance you<br>
do these. If I see people are not doing as well as in the past I will<br>
attribute this to people not reading the book and doing the EOC<br>
assignments and only doing the MC problems. I may then decide<br>
to include more of these EOC problems in the on-line homework<br>
for credit. I would prefer not to since I want you using the book and<br>
EOC problems to figure things out and not be "afraid" of making a<br>
mistake or needing help from someone or the solutions manual.<br>
But you have to, use the help correctly and not lean on it too much<br>
(i.e. don't just read the solutions manual and think you know it).<br>
<br>
In which order should you do these? It kind of depends on how<br>
things are going for you. You get credit for the on-line homework<br>
and do lose points for hints and wrong answers. Doing the book<br>
problems first will make the on-line homework a little easier. On<br>
the other hand the on-line homework does have tutorials available.<br>
Technically, so do the book problems, it's called the solutions<br>
manual found on Carmen. If you get stuck on an EOC problem<br>
you can get a hint from the solutions manual and feedback on<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">how to approach and do the problem.<br>
<br>
I suggest you do the book problems first. If you have trouble you<br>
can peek at the solutions manual on Carmen for help (and then<br>
do another similar problem). That doesn't cost you anything. These<br>
don't count for a grade so getting one wrong or getting hints won't<br>
cost any course points. This allows you to try working through the<br>
problems and material w/o worrying about whether you're going to<br>
lose points for doing something wrong. You learn more from your<br>
mistakes and by fixing them than by just guessing and getting the<br>
right answer or always getting help from someone. By doing these<br>
first you should already know the material pretty well before<br>
attempting the on-line homework. Do at least 80% of the EOC<br>
problems I've assigned (including some from the Additional Exercises<br>
and Integrative Exercises) before attempting the on-line homework.<br>
You can then use the MC as a review before the quiz each week.<br>
It should go quicker and you can maximize your points since you<br>
will have already done the book problems and have a good idea of<br>
what to do. I will say this again, doing just the on-line homework<br>
isn't enough if you hope to do decently. If you want to do really well<br>
you have to do a lot of problems and of course understand what<br>
it is you're doing.<br>
<br>
The on-line homework does have due dates. They are there to<br>
try to force you to at least do some homework and not fall behind.<br>
They are "flexible" and could change, maybe pushed back from<br>
the due dates I'll show (doubtful I would make them sooner). I<br>
actually pushed back the MC homework for section 14.3 from<br>
this weekend to next weekend since we hadn’t finished that<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">until this past Wed.<br>
<br>
I keep stating how important it is not to fall behind and there are<br>
many of you who have not started the MC problems. Hopefully<br>
you've started the EOC problems. But you absolutely MUST<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">do the MC as they are for credit.<br>
<br>
You would want to complete the MC stuff which apply to the<br>
sections covered by a quiz before the quiz. I'll let you know<br>
which those are before the quiz. For each quiz I put the sections<br>
covered and relevant the homework problems, both EOC and MC,<br>
on my web page. I also e-mail it.<br>
<br>
My belief is, if you do ALL the assigned homework problems (and<br>
then some extra, MC) AND understand what you are doing AND<br>
understand the concepts in the book AND do things the proper<br>
way (read the "How to Study" link) AND seek help when you<br>
need it, you should be fine. That's a lot of ANDs but it's pretty<br>
much what is necessary. The problem is many people do NOT<br>
do the proper things. For the most part, it's up to you to be<br>
responsible enough to do homework and come for help. I will<br>
provide as much help as possible but it ultimately comes down to<br>
you being responsible enough to do the proper things.<br>
<br>
This would apply even w/o on-line homework. We shouldn't have<br>
to "force" you to do the work you need to do to learn the material.<br>
You're here to learn and you do so by doing the work, not by simply<br>
showing up to lecture and doing the minimum possible.<br>
<br>
You can find the highly suggested "assigned" EOC homework<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">on the class web page,<br>
<br>
<u><a href="https://www.asc.ohio-state.edu/zellmer.1/chem1220/chem1220.htm">Chemistry 1220 - Sp2</a>1</u><br>
<br>
Once there you will see links for "Homework". Click on the<br>
appropriate link for the edition of the textbook you're using<br>
(this should be the 14th ed. for everyone at this point).<br>
What you will find are the end-of-chapter problems you should do.<br>
I've listed the EOC problems as 2, 4, 6, etc. For example, for the<br>
Chapter 11 review material, this means 11.2, 11.4, 11.6 in the<br>
EOC exercises.<br>
<br>
Just looking at the publisher's solutions is NOT the same as<br>
YOU doing the homework problems. YOU must be able to<br>
do them on your own in a reasonable period of time. Chem<br>
1220 involves lots of concepts and equations. You need to<br>
understand these concepts and truly understand the equations<br>
(when and how to use them, what the eqns tell you about the<br>
relationships between the variables in the eqns, etc.). If you<br>
attempt the homework problems I've assigned but can't do<br>
them on your own or don't understand the concepts and eqns.<br>
you should seek help from me and/or the TAs and then work<br>
some more problems. If you don't do this you won't do well<br>
in the class. <br>
<br>
You MUST keep up with what we are doing in class. If <br>
you are behind, even by one lecture's worth of material, <br>
you will find it will be difficult to catch up and understand <br>
things. This is not a course you can put off for another <br>
day. You will need to spend 2.5-3 hours EVERY DAY in<br>
order to do well. You should be spending about 12 hours<br>
per week (sometimes less, sometimes more) on the lecture<br>
material and 3-4 hours on lab to prepare for one lab and write<br>
the report that's due. Students often tell me (after failing the first<br>
midterm) they spend a lot of time every week studying. When I <br>
ask for specifics I'm often told "a lot" is 6 or fewer hours <br>
a week. That won't work. Always skim 1/2 a chapter ahead<br>
in the book before class so that lecture will make a little more<br>
sense. You should then finish the sections in the textbook and<br>
associated homework for sections covered in one lecture before<br>
the next. I generally follow the order of the sections in the book.<br>
This way you are keeping up and the next lecture will make more <br>
sense. You should be done with Friday lecture material by Saturday<br>
or Sunday. This means you should be done with ALL the assigned<br>
sections and homework for the week by Sunday. Read about how<br>
to study for this class at the following link,<br>
<br>
<a href="https://www.asc.ohio-state.edu/zellmer.1/studying/studying_1220_normal.txt"><b>Studying Methods - 1220</b></a><br>
<br>
This class is quite a bit tougher than most, mainly because most<br>
of you have not seen most of this material in high school and even<br>
if you have probably not at the level of understanding we expect.<br>
We cover a lot of conceptual things and that is often something<br>
most students did not see in high school or in other classes. <br>
<br>
You will be busy with this course. It takes a lot of hard work<br>
and effort. It will be mostly up to you how much you learn. <br>
Probably 90% of what you learn will be on your own with about<br>
10% coming from me, both in class and by you asking me<br>
questions. I'm always very willing to help and will help as much<br>
as I can. You can always come by my office or e-mail me questions. <br>
You will get a lot of e-mails from me throughout the semester. When<br>
someone asks me a good question I usually send my answer to<br>
the whole class (usually when there's one person with a question<br>
there's probably several more with the same question). I will also<br>
send answers to questions I've received in previous years. As a<br>
matter of fact, the answers to some of those can be found at the<br>
"Helpful Tidbits" link on the 1220 class web page (not Carmen).<br>
Check this page and my other links for answers to your questions<br>
before e-mailing me. However, if you still don't understand something<br>
do not be afraid to seek me out in my office or send an e-mail.<br>
