Randomize order of blocks

Randomize order of blocks

Hi, list.

Some time ago I realized ConTeXt has "blocks" which allow one to make
quizzes, exams and related with ease. However, I want to know if there's an
option to randomize their order when printed. Thank you in advance.

Hi Jairo,

One can indeed make quizzes and exams with randomized order of problems, randomized values and even randomized names of functions and variables.
I have some examples which I have been using for several years (they are useful especially in these days of giving exams online…): I can send them to you as they are, or if you tell me what kind of problems you want, then I can adapt my examples before sending them to you.

Best regards: Otared

Re: Randomize order of blocks

Following up my previous message, here is an example:

%% begin shuffled list of exercises
\setuprandomize[2021]

\startluacode
	function shuffle(tableau)
		local maxsize, t, tt
		maxsize = #tableau
		tt = {}
		t = {}
		for i = 1, maxsize do
			t[i] = {}
			t[i]["columnOne"] = tableau[i]
			t[i]["columnTwo"] = math.random(1,100*maxsize)
		end
		table.sort(t, function(a,b) return a.columnTwo < b.columnTwo end)
		for i = 1, maxsize do
			tt[i] = t[i]["columnOne"]
		end
		return tt
	end
\stopluacode

% We define three arrays
% with the names, the functions and their derivatives
% One could also add a ListOfVariables...

\startluacode

	ListOfNames = {
		"f",
		"g",
		"h",
		"u",
		"v",
		"F",
		"G",
		"H",
	}
	
	ListOfFunctions = {
		"\\cos(x^2)",
		"x\\sin(x)",
		"\\tan(x)",
		"x^3 - 3x^2 + 1",
		"\\frac{1}{1 + x^2}",
		"\\sin(\\log(x))",
		}
		
	ListOfDerivatives = {
		"-2x\\sin(x^2)",
		"x\\cos(x) + \\sin(x)",
		"1 + \\tan(x)^2",
		"3x^2 - 6x",
		"\\frac{-2x}{(1 + x^2)^2}",
		"\\frac{\\cos(\\log(x))}{x}",
		}
		
\stopluacode

\starttext

% We define a buffer and a shuffled list of integers

\startbuffer[test-derivatives]
\startluacode
	ShuffledList = shuffle({1,2,3,4,5,6})
\stopluacode

Let $\cldcontext{ListOfNames[ShuffledList[\recurselevel]]}(x) := \cldcontext{ListOfFunctions[ShuffledList[\recurselevel]]}$. Prove that
\startformula
\cldcontext{ListOfNames[ShuffledList[\recurselevel]]}'(x) = \cldcontext{ListOfDerivatives[ShuffledList[\recurselevel]]}
\stopformula
\stopbuffer
	
\dorecurse{6}{\blank[medium]{\bf Exercise #1.}
	\getbuffer[test-derivatives]
	}

\stoptext

%% end shuffled list of exercises

Nice. I had something a little bit different in mind, but your examples
gave me some ideas, especially the shuffling stuff. If I have something new
to add, I will share my results with the list. Thank you a lot.

Best regards,

Jairo
