@firstfold - is it a window blind/shutter?

my entry is a Hobbes bookmark.( Hobbes as in Calvin and Hobbes.)

[Gerardo]

OH MY GOD! I love Calvin and Hobbes!

It would be perfect for my "The Revenge of the Baby Sat" and "Scientific Progress Goes Boink" !

The Nose - an eyeglass stand
from one 21x25cm rectangle of construction paper backed with aluminum foil

This model is useful for everybody wearing glasses (or occasionally shades). It solves the dilemma of storing them in a conveniently reachable location without looking messy.

It is time to reveal my mystery entry. It is folded entirely from rectangels and assembled without glue. The total number of rectangles depends on which example is used.
This item is called "Quiz Sticks" and it has two very serious goals which are shown in the first video.
You should be aware that the sample quizes presented are deliberately flawed so as to serve as discussion points for understanding and improving the construction of tests.



One question, one answer per each set of sticks.
This is a flawed quiz - depending on what the goal is.
You can answer each by counting digits rather than actually performing addition.
You can also answer the question by trial and error because the star reveals the correct answer.



One question with 4 answers for each set of quiz sticks.
One problem with this quiz is the orientation of the "Rectangular Prisms" in the diagram and an understanding of the concept of height.
Trial and error alone is not enough for this quiz set-up.
Can you spot other problems with these quiz questions?





I have a third video which explaines some of the complexities of the second example but I will let you first get your brain around the basic premis. Make sue to look at the References at the end of the second video. It adds a little humor to this serious discussion and shows just a bit of my background for designing test items.

You expected us to guess this ?!

It's a really creative idea firstfold. Would you please post this in the Inter-forum Challenge thread as well? That way I'll ask my friends to finally post your model in the other forums .

You expected us to guess this ?!

I thought it might work like an example of a test item that can be considered either good or bad depending on the goal. If the goal were to figure out who is good at guessing, then this is a really bad item. It is like test designers who try to make all questions as hard as possible - usually they don't work too well to discriminate different levels of ability. If, on the other hand, the goal were to generate guesses that might be good entries for this challenge then it was a fairly good item. I got 11 guesses from here, Youtube,and Flickr and some ideas that I will try to fold if no one else makes the attempt. Thanks all for making the effort, I consider all your guesses to be creative successes.

at fisrt glance i thought it is mr Potato

What's the minimum number of rectangles you need for the Quiz Sticks to work?

What length and width did you use in each?


It's an interesting idea. Did you invent the whole idea or does there exist something similar made with other materials? If I understood it correctly it's more for matching the correct answer with the question rather than separate multiple choice questions, right?

Thanks for sharing firstfold

[firstfold]

As far as I know there is nothing else quuite like my "Quiz Sticks". It can either be used for matching or for up to 4 answers per questions with multiple choice, or in a matching, multiple choice combo. Notice the second example, you must rotate the stick to find the correct answer.

Here is a count of the rectangles used in its construction.



PLEASE NOTE: While it can function as a device for delivering quizes, "Quiz Sticks" is best used as a way to train students and teachers about the characteristics of tests. It is a physical demonstration of how questions and answers are arranged in sets. Theoretically, the more homogeneous the set of answers and the more homogeneous the answers, the more difficult the test. A test can be either too difficult or too easy because the reliability of the test suffers. Teachers sometimes introduce clues to answers in the distracting answers selected. Sometimes this improves test quality and sometimes it has the opposite effect.
Language in testing is a very tricky issue. Can you see how the "Diagonal" of a Cube could correctly be considered its height depending on how height is defined?

my submission will be a flaping crane book mark
ever wanted a flaping crane everywhere... here one of the solutions... keep it in books you read. Simple it is, moving the tail make the crane flaps ^.^
it is simple and neat





flapping in action ^^




the model that i made was made by using half a square of A3 copy paper of (ratio 1:2)

[GWB origami]

alother entry i had in mind is my rose cup!

it can hold tacks and if folded out of waterproof paper, water

[shangoob]

Hello there..
This is my second entry.
This model which I call "enviro-shirt'" is a shirt that i designed of a "single sheet" of "A0" "Rectangle".
I made this model aiming to be a subtitute for t-shirt stands, and can be used as models for window-shopping, I use this model recently to hang my straw hat .
I think this model -if taken into consideration- can help the environment replacing plastic models that are used in most of clothes shops.
smaller models can be used for decorations. They can also be painted to look stylish and good-looking. My friend would probably paint them as soccer shirts for his best players :p

OK
Here's my contribution to the english forum:



AN A4 SHEET OF PAPER

With it, you can fold/make:
- snowblue's mobile phone stand(and personalise it with my pen)
- ray95's vase
- thebigbluevan's CD case
- malifold's A4 sheet of paper
PLUS everything else made from smaller than A4 sheets(like just about all the other models for this challenge!)

HAHAHA... I don't know malifold, can you provide diagrams ?
