Redstar Posted January 7, 2009 Report Share Posted January 7, 2009 (edited) My Type I was 17 pages long and my Type II was 14 pages long. I got 20 in both, but as long as you get a 17 you're at a borderline 7. As far as I know, most of the places where my friends were marked down was in using the correct mathematical terms and in explaining the limitations to their conjectures. Most of my friends managed to reach a correct general statement and explained their method correctly, but since they didn't explain the limitations to their general statement (e.g. only works for positive numbers, or something along those lines, obviously with further explanation) they were marked down.

avrila Posted January 7, 2009 Report Share Posted January 7, 2009 I remember my teacher said last time that a good portfolio should be only 20 pages and not more than that. It means that the teacher want to see how well we organize our data by using limited space. They want to see use appropriate method like table, graph and so forth. But most of the student in my college exceed the 20 pages. And we still do not know the mark yet...And we haven't started with the Type II. Well some of you are too fast.

Mahuta ♥ Posted January 8, 2009 Report Share Posted January 8, 2009 It actually depends, because some of the projects, I jsut couldnt make any shorter, since my validation was the most important thing, I had to make it fully detailed, and I still got 3 18s.I guess we are yes, LOL. But it will be done, I'm sure. My Type I was 17 pages long and my Type II was 14 pages long. I got 20 in both, but as long as you get a 17 you're at a borderline 7. As far as I know, most of the places where my friends were marked down was in using the correct mathematical terms and in explaining the limitations to their conjectures. Most of my friends managed to reach a correct general statement and explained their method correctly, but since they didn't explain the limitations to their general statement (e.g. only works for positive numbers, or something along those lines, obviously with further explanation) they were marked down.That's really good, but be careful, i had someone in my school who got 2 20s and 2 19s, and they were marked down three marks on each, and the teachers still can't see a reason why the IBO did that. I got 3 18s, and the math departement is afraid I'm going to be marked down.It is excellent, but watch out. Reply Link to post Share on other sites More sharing options...
Redstar Posted January 8, 2009 Report Share Posted January 8, 2009 (edited) Yeah, I have no idea if the IBO has marked me down. I still got a 7 overall in Maths, but as far as IAs go all I know are the grades my teacher gave me. Edited January 8, 2009 by Redstar Reply Link to post Share on other sites More sharing options...
thinkgreen95 Posted January 25, 2009 Report Share Posted January 25, 2009 how long was your crows dropping nuts one? cuz I'm doing that one now, and I'm a freshman so this is my first IA and I have no idea how long a good length is...HELP!!!!!(please) Reply Link to post Share on other sites More sharing options...
cordi827 Posted February 13, 2009 Report Share Posted February 13, 2009 heyy i'm new at this too! ahh so i created all of the graphs on excel and they all show an upward curving graphi dont want to sound stupid (though I might) but does anyone know what kind of graph this is or how it's possible to model it?it's killing me! i would be EXTREMELY GRATEFUL for your help, you have noo idea!

It'd be helpful if you could show us a pic... lots of graphs curve upwards.no worries i got the answer from my friend, she's smarter than me in math.it's exponential...she said something like exponential to the 2nd degree??whatever that means hahathanks so much for answering though Reply Link to post Share on other sites More sharing options...
the_kidd Posted June 3, 2009 Report Share Posted June 3, 2009 Is 7 pages long enough for a math portfolio?or does it need to be in the teens Reply Link to post Share on other sites More sharing options...
deissi Posted June 3, 2009 Report Share Posted June 3, 2009 Usually 7 is short but who knows - maybe you're just concise. Reply Link to post Share on other sites More sharing options...
Toffu-san Posted June 4, 2009 Report Share Posted June 4, 2009 I have done a portfolio Type 1 and it has 27 pages. I write a lot of evident things but.... I think that at least 10 pages. Reply Link to post Share on other sites More sharing options...
Sandwich Posted July 7, 2009 Report Share Posted July 7, 2009 If it's short you haven't repeated yourself and pointlessly explained things enough, in my opinion. That seems to be where the marks are!VictimofIB, you should check out the board. There should actually be a thread for that portfolio, or if you really can't find one, perhaps make a new one? Usually other people have done it and started discussions already where you can find tips and other people's thoughts on them. Reply Link to post Share on other sites More sharing options...
Tilia Posted July 7, 2009 Report Share Posted July 7, 2009 I don't think one should be too obsessed with the length of it. It's not a very good indicator of its quality Reply Link to post Share on other sites More sharing options...
Peachez Posted July 24, 2009 Report Share Posted July 24, 2009 Recieving a 17 on your math portfolio is a very good result.I am working on my math portfolio type 1 currently and I think what matters the most is the useful work and make sure that the audience (in this case, the grader) will understand what you are doing, hence you should understand what you are doing inside and out.Here are some things I found on the Intenet which you might find useful.1. Elements of a successful IB Internal Assessment.Basic elements of a good Math Studies Project or Math SL/HL Portfolio piece:· Correct answers throughout.· All questions answered in a logical order.· Audience is the teacher.· Identify and address the principal goal of the assignment.· Written explanations of difficult or lessobvioussteps in work.· Wordprocessedincluding use of technology for graphs and equations.Elements of superior work:· Attention to detail.Ø Consistent significant figures or decimal place rounding.Ø Use of proper notation such as “ »” for approximations.Ø Avoid calculator notation such as 4*5, x^2, or 2.3E4.Ø Graphs are clear with logical scales and labeled axes.· Work stands alone.Ø Audience is another student of the same level.Ø Reader doesn’t have to refer to the assignment sheet.Ø Reads smoothly and effortlessly.Ø Answers are not numbered unless required.· Single wordprocesseddocumentØ Integrate an equation writing program, spreadsheets, graphing program, etc.Ø Comment on everything included.Ø Explain steps each time a new mathematical process is used.Ø Avoid repetition of processes already explained.Ø Graphs, charts, etc. appear on the same page where they are explained.· Student goes beyond the assignment with insight and sophistication.Ø Identify and address the hidden goals of the assignment.Ø Try to get into the mind of the writer of the assignment.Ø Most good assignments leave some space for the top students to explore.· Student uses a variety of mathematical approaches.Ø A good assignment will require the use of many kinds of math.Ø A good question will often have several possible approaches for the solution.· All math used is relevant to the task.Ø No fluff or spacefillers.2. Tips to the students.· Work through all problems with pencil and calculator before writing it up.Ø Gives an overall feel for the project so that that student can start to address the main goal,and even insights, right from the start.· Write a brief introduction rather than jumping right in to the first question.Ø Sets a tone of readability.· Math SL/HL students can pretend that they are writing a chapter in a textbook.Ø Encourages students to fully explain each step, remembering that their audience is anotherstudent from their course of average ability.Ø Students can have fun with creative formatting.Ø Take pride in the look and feel of their work.· Math Studies students can approach the IA Project as they would a science lab.Ø Write a hypothesis.Ø Collect data.Ø Analyze data.Ø Draw conclusions.Ø Discuss possible errors or improvements. 2 Reply Link to post Share on other sites More sharing options...
idIB Posted July 24, 2009 Report Share Posted July 24, 2009 I got 17 on one of my portfolios and it was 8 pages (9 including the title page); it is content that really matters. Just try to include graphs in any portfolio and you should be alright, if you explain every step that you doa good graphing technology is Autograph, just download the free trial Reply Link to post Share on other sites More sharing options...
hanz Posted July 28, 2009 Report Share Posted July 28, 2009 Hey i was wondering and asking, does the teacher give you hoe much you get in the portfolios ?! no right ? our math techer tells us no Reply Link to post Share on other sites More sharing options...
Sandwich Posted July 28, 2009 Report Share Posted July 28, 2009 Your teachers grade your work, but then some of the portfolios are then sent forward to the moderators. If the moderators disagree with the way your teachers have marked, they alter all the grades in accordance. So say somebody's work had been given a 17 (usually just a 7), but the moderator disagreed and marked it down to a 15 (usually a 6), EVERYBODY'S work would go down by two marks. So really, the teacher does the hard work in giving the initial marks (and setting, therefore, the relative marks between the class), and then the moderator decides on your final grade when they look over your teacher's marking and move it up, down or keep it the same. 1 Reply Link to post Share on other sites More sharing options...
sweetnsimple786 Posted August 4, 2009 Report Share Posted August 4, 2009 Hey i was wondering and asking, does the teacher give you hoe much you get in the portfolios ?! no right ? our math techer tells us noSandwich above is right. ^^Some teachers give you their scores [the unmoderated ones], while others don't. Who knows why? Maybe they don't want hate mail from students or something? My teacher gave us the IB rubric that she graded from with how many points we got from each category and such. It was nice. But I know my Spanish and English teachers strictly refused to give us scores. They said it wasn't allowed. Whatever. Reply Link to post Share on other sites More sharing options...
Chelleee Posted August 8, 2009 Report Share Posted August 8, 2009 hmm,well my Type I was 24 pages long and i got a 19/20 for it, a girl in my class did get 20/20 but the teacher purposely put her down as a 19 because of the fact that, it is possible for the marks to be scaled down.currently doing a Type II! hope i do well on it, need to pull up my 12 p.s - the HL kids assignments for math we're around 40+ pages, it was something to do with an elevator of some sort.

Holy Moly Posted September 30, 2009 Report Share Posted September 30, 2009 I did a practice portfolio which was only 4 pages long and got 14/20. (Probably would've have been better but I went on a trip for 10days during our IA. Reply Link to post Share on other sites More sharing options...
