I don't know how much you've looked at how tuxmath generates math
question lists, but basically a lesson file sets a series of criteria
for questions:

- allowed math operations (addition, subtraction, multiplication, division)
- ranges of allowed numbers for operands
- whether to allow negative numbers
- format of question (i.e. 1 + 1 = ?, 1 + ? = 2, or ? + 1 = 2)

and so forth.  There are also some variables related to how answered
questions are handled - in the "lesson" games, correctly answered
questions are considered "done", and the lesson ends with a win when
all the questions have been handled correctly.  In the "arcade" games,
all questions get reinserted into the list so the game goes on
indefinitely until the player runs out of lives.  In both modes,
questions which are not answered correctly get reinserted so the
player sees them again.  There is an option to reinsert multiple
copies of missed questions so as to give extra practice on those
facts.  Finally, the code contains functions to support the use of the
just the "missed questions" from the previous game as the question
list for the next game, although we've never implemented a way to use
this feature.  So, some of these features might be useful in your
project, but they might not be sufficiently flexible for your needs.

What tuxmath does not currently provide is the reading of a list of
arbitrary functions from a text file.  I think we may want to do
something like that for your project.

I read your blog, and am eager to hear more about specifics, or to
help you work them out.  It seems to me that there are at least two
ways in which this adaptive instruction can be applied:
1. Within the same math game, use the player's initial performance to
adjust the subsequent questions.
2. For subsequent games, adjust the questions based on results from
previous games.

Yes - I've thought for some time that this was a shortcoming of the
program.  The only "teaching" is when we show the answer when the
igloo gets hit, plus the factoring hints we put in at the start of
each level in factoroids.  But there isn't any illustration of the
concepts of math.  There are plenty of ways that new activities could
be designed for these purposes, e.g. having Tux combine groups of fish
to illustrate addition, or having him build stacks of ice blocks in a
grid layout to illustrate multiplication.

I think the existing games have been shaped a lot by the ages of our
kids at the time when the games were written.  My daughter was a
second-grader when I started trying to make Bill's original comet game
more flexible, and she was a fourth-grader doing a lot of factoring
stuff when I proposed the factoroids game.  Maybe we need someone with
pre-school or kindergarten kids to get interested in coding up a new
activity.

Hi Tim,

Thanks for the feedback. :)

I had an interactive interface in mind, where the final decision would be on
the player if he would like to follow the topic the game suggests or choose
another one as per his wish.

2. What are your thoughts about per-user storage? Are you going to employ

I will initially implement a storage structure for the Linux model, and than
for the "school mode". Imo, this should be more valuable if I implement it
for the "school mode", but I am not familiar with the code. I will try to do
that :)

For 3.), modelling how much challenge a user is willing to take seems
difficult. Rather than making decision on the latency in re-starting the
game, we can base it on the progress: If the student is able to save the
igloos, adjust the other game variables to provide more challenge; if a
student is performing poorly, we may want to slow the speed of comets and
likewise, adjust other game variables. But again, this approach assumes the
amount of difficulty one is willing to take. What are your opinions?

There is an interesting approach
Animalwatch<http://animalwatch.arizona.edu/> (It's
a tutor for pre-algebra mathematics) uses for this which is described
here Using
the student model to control problem
difficulty<http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.38.7068&rep=rep1&type=pdf>.
I am thinking of using a approach on similar lines, will post it shortly.

5. Given this tuxmath-as-the-teacher mode of thinking, do we need to think

iiuc, this means using different teaching strategies to cater to the varying
needs of the students (like some may like to receive more feedback to stay
motivated, a pedagogical agent may be more of help to others). But given
that the domain here is elementary Mathematics, I find it hard to think of
an explicit teaching mechanism. Do you have some suggestions?

Thanks,
Siddharth

Re: [Tuxmath-devel] GSoC project on "Personalized, adaptive game-play to improve learning in Tuxmath"

[Tim H. <ho...@wu...>]

Hi Siddarth,

I like it very much. Some concrete feedback, mostly a set of questions asking 
for more detail:

1. When you say, "topic suggestion," are you thinking of some interactive 
interface from which the user chooses a task? Or is the "suggestion" an 
internal one, and the game will execute whatever parameters are suggested?

2. What are your thoughts about per-user storage? Are you going to employ the 
Linux model (store in the user's home directory), or are you going to use the 
infrastructure in the "school mode"? Or are you planning on not saving data 
across sessions at all? (Without saving, it will be hard to test and debug, so 
I don't recommend the latter.)

3. I have the sense that kids differ quite a lot in terms of how much negative-
outcome they can tolerate: some will plunge right back in after they lose all 
their igloos, others will be bothered if even a single igloo gets hit by a 
comet. Those that enjoy the tension will appreciate being challenged, those 
that do not will probably feel more comfortable if they are consistently 
performing at 95% or higher.
It would be really interesting if it were possible to model not just the 
student's mastery, but also what level of failure/challenge is acceptable to 
the student. Naturally, this seems hard. One option would be to ask for 
feedback from the student, and a second might be to pay attention to the 
latency in re-starting a new game of tuxmath. If it is a few seconds, the kid 
seems ready for more. If it's a few months, perhaps the kid got scared off. But 
obviously it's questionable how reliable such information will be.

4. In your section on "modifying the game variables," certainly the speed is 
an important parameter. But a more interesting---and more conceptually 
challenging---issue is how to decide which _type_ of problems to pose. Is the 
kid ready for addition facts up to 10, or should we stick with 0 to 5? How can 
you tell when the kid is ready for multiplication?

5. Given this tuxmath-as-the-teacher mode of thinking, do we need to think 
somewhat about creating mechanisms to explicitly teach, rather than just let 
them practice things they've already been taught?

Again, it looks like lots of fun ahead. I'm glad you're tackling this.

Best,
--Tim

Re: [Tuxmath-devel] TuxMath for Haiku

The font is installed, that's not the problem, the problem is the path,
Haiku doesn't use /usr/share ... and TuxMath is compiled with a
prefix /boot/apps/TuxMath, the font is in a subdirectory but due to the
hardcoded path(?) isn't been picked up ...

[Tuxmath-devel] TuxMath-2.0.3 is in MacPorts

[David B. <dav...@gm...>]

Hi,

The macports (http://www.macports.org) devs have uploaded current
portfiles for tuxmath-2.0.3 and t4k_common into macports, so now you
can get the latest tuxmath onto your mac with:

sudo port selfupdate
sudo port install tuxmath

(assuming you have macports, that is).

The mac build has the two bugs mentioned earlier, namely:
1. any svg image that gets scaled is displayed incorrectly, almost
certainly an endianness issue with the RGBA channels getting
transposed.  This doesn't affect gameplay but does make the game look
weird, particularly in windowed mode.  In fullscreen, it only affects
a couple of the menu icon sprites.  In windowed, it affects the menu
icons, the big Tux on the menu pages, and the comets within the games.
 Also, the cached png images of these under
~/.t4k_common/caches/images/ are similarly incorrect, but only the
scaled ones.  So, I think this bug is somewhere in t4k_loaders.c, but
there is quite a sequence of functions that get called to do this, and
I haven't yet been able to get to the bottom of it.  We ought to write
a small test program for t4k_common to make this easier to debug.

2. In the network game, if a mac client is connected to a server on
another machine, it doesn't remove the comets from the screen when the
questions are answered by another player.

I'm in a better position to sort out #2 since most of the relevant
code was written by me.

I'd encourage anyone on this list with a Mac to try out the new build,
and hopefully help debug these problems and anything else we find.

Best,

David Bruce

[Tuxmath-devel] t4k_common and TuxMath 2.0.3 on Mac OS-X

[David B. <dav...@gm...>]

Hello,

For the last few days I've been working on getting tuxmath's MacPorts
build updated, and I now have it running on our Snow Leopard iMac.
I've submitted a new Portfile for t4k_common, and an updated Portfile
for tuxmath.  Since I'm not a MacPorts committer, I have to wait for
the new ports to get added to the project, which usually takes a day
or two.

The Good:
- very few problems getting t4k_common-0.1.1 to build, required a very
minimal source patch which is also added to git.
- a couple small issues with tuxmath's source, which I addressed in
the 2.0.3 source release, which is also posted on Alioth.
- The program mostly works fine, including SVG scaling, SDL_Pango,
network play, all of which are new to the Mac platform for us.
- successful automated building of dmg file for binary installation.

The Bad:
- bug in network game - if a Mac client connects to server on another
machine (Linux in my test case), it sometimes fails to correctly
handle the messages to remove comets that were answered by another
player.  The other messages (new questions, score updates) work fine.
If the server is on the same machine, everything works fine.
- strange display bug in windowed mode - the images for which we are
using svg scaling appear with wrong colors and alpha, making Tux look
like a ghost!  My daughter howled with laughter.  Fullscreen looks
fine, and non-svg images display correctly.  It probably has something
to do with endianness when we create the scaled images as pngs.
- dmg file is huge, as in enormous - ~120MB.  It includes bundled libs
for literally everything needed to put tuxmath on the screen,
including about 20 libs that go into Xorg.
- AFAICT, no way to build ppc version on Snow Leopard with MacPorts.
- Not sure if the dmg will work on 10.5, although MacPorts itself ought to work.

[Tuxmath-devel] t4k_common added to mingw-cross-env

[David B. <dav...@gm...>]

Hi,

t4k_common has been added to the mingw-cross-env project, so it is now
even easier to create the cross-built win32 package for tuxmath on
Linux.  Since t4k_common was just added, you need to get the
development version of mingw-cross-env from that project's mercurial
repo:

http://mingw-cross-env.nongnu.org/#development

Make sure you have the needed tools installed on your system:

http://mingw-cross-env.nongnu.org/#requirements

Then simply run:

hg clone http://hg.savannah.nongnu.org/hgweb/mingw-cross-env
cd mingw-cross-env
make t4k_common

and the complete cross-build setup will be downloaded and installed.

Then just go to buildw32/ in your tuxmath git clone.  In
cross-configure.sh, look at MINGW_DIR and make sure it matches the
location where you installed mingw-cross-env (the default is
/opt/mingw-cross-env).

Then simply run (from buildw32/):

./tmwin.sh

and the win32 installer should be automatically built.  You need NSIS
to generate the installer file, so you might need to run "sudo apt-get
install nsis" or an equivalent.

That's it - it should now be really simple for anyone to make and test
the win32 crossbuilds.

Best,

David Bruce

Just curious, any reason why you don't want to use the existing one
already on Freenode?

If it's because I still "own" the channel permissions/authorizations
(which, I'll be honest, I haven't checked if I do, but it's very
likely I do as I was the one who started all this so long ago) I'd
gladly give them over to the appropriate persons.

Hi Everyone

I want to start a new IRC channel for tux4kids and its project at freenode.
It will help current devs and new devs to assemble at one place and share
their ideas and new changes in dev branches.

So if anybody interested in it. Then ping me on gmail or gtalk.

I saw that and confirmed it in the new windows build.  The quite
strange thing is that this bug does not show up in the Linux build,
even though nothing being done at that point would seem to be
platform-specific.  I couldn't get it figured out before I had to
leave for work this morning.  As it seemed to be less critical, I
decided to release this version anyway.  We will try to get it fixed
in the near future.

[Tuxmath-devel] TuxMath - Fixed Windows release (2.0.2)

[David B. <dav...@gm...>]

Hi,

I'm back from vacation, and I had time to work on getting a fixed
release of tuxmath-2.x.x out.  The main reason was the broken win32
installer file I hastily posted for tuxmath-2.0.1, which was the
result of a too-old version of NSIS on my netbook, and not something
in tuxmath itself.  The win32 build is posted on Alioth and
SourceForge.  I've downloaded the binary, and it seems to install and
run correctly.  I'll try to get a tarball and the signature and
checksum files up by the end of the day.

Not much change for this release, but there are a couple of new fixes:
1. Fix of a recently-introduced crashing bug on creation of a powerup
comet (Arcade game).
2. Fix of problems with score drawing in turn-based multiplayer game.

There is still a bug that prevents the turn-based multiplayer game
from being able to be started, which for highly unclear reasons only
occurs in the windows build.  AFAIK there isn't anything very platform
specific going on at that point.

Anyway, I hope this release is more useful, and look forward to
ironing out remaining issues in the next few weeks.

Best,

David Bruce

In that build, the file was indeed called "options.cfg" - the README
was wrong.  For 2.0.0 and later, the options/lessons files really do
end in ".txt" on windows (on other platforms, no extension is used).

Irrespective of file name, it is a plain ASCII text file that can be
edited with any text editor, e.g. Notepad on windows.  However, prior
to 2.0.0, the files still have Unix-format line endings, meaning it
will look like a single extremely long line in Notepad.  More
sophisticated text editors (e.g. Vim) will recognize the Unix format
and display it correctly.  That format discrepancy is also fixed in
the 2.x.x series - in the windows package, all the text files have the
windows-friendly format.

Short answer - wait for the 2.0.2 release today, then you can use
Notepad to edit that file, which is well-commented, and then play your
custom game by choosing "Play Custom Game" from the menu.

Thanks,

David Bruce

Sorry to hear that - I built 2.0.1 very rapidly on a laptop in an
airport between flights, and I didn't have any opportunity whatsoever
to test the windows build before I had to get on the plane.  I won't
be able to do anything about it until I get home next week.

Just in case, you might check the version on sourceforge, in case the
corruption occurred during the upload process.  Apart from that, the
builds on alioth and sourceforge are supposed to be exactly the same
file.

Again, sorry for the frustration!
