We have developed tools that can help teachers generate hundreds of problems that are similar to a given problem for use in exams (to prevent plagiarism). These tools can also help students by generating personalized workflows with a dynamic progression of problems of increasing difficulty. We believe that this technology will become an integral part of traditional\/online classrooms, replace expensive books containing practice problems, and offer unique value with personalized instruction leading to better and quick learning.<\/p>\n<p>We have developed automatic problem generation tools for a variety of subject domains including algebraic proof problems, procedural math problems, sentence completion SAT problems, logic problems, automata construction problems, and board-game problems. These tools build over state-of-the-art advances in multiple computer science disciplines including logical reasoning and natural language understanding, and also\u00a0leverage\u00a0domain-specific knowledge associated with a given subject domain.<\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/li>\n\t\t\t\t\t\t<li class=\"m-0\">\n\t\t\t<h4 class=\"accordion-header\">\n\t\t\t\t<button\n\t\t\t\t\tclass=\"btn btn-collapse m-0\"\n\t\t\t\t\ttype=\"button\"\n\t\t\t\t\tdata-mount=\"collapse\"\n\t\t\t\t\tdata-target=\"#collapse-3\"\n\t\t\t\t\taria-expanded=\"false\"\n\t\t\t\t\taria-controls=\"collapse-3\">\n\t\tAlgebraic Proof Problems\t\t\t\t<\/button>\n\t\t\t<\/h4>\n\t\t\t<div class=\"collapse\" id=\"collapse-3\">\n\t\t\t\t<div class=\"accordion-body\">\n\t\t\t\t\t\t\t\t\t\t<p>Given an algebraic identity (like the red\u00a0problem below), our tool [<a href=\"https:\/\/www.microsoft.com\/en-us\/research\/publication\/automatically-generating-algebra-problems\/\" target=\"_self\">AAAI 2012<\/a>] is able to generate fresh algebraic identities (shown\u00a0as green problems below) that are similar to the input identity.

The teacher can modify the constraints to control the variants that get generated. A more restrictive set of constraints will lead to fewer problems being generated, but those that might be more similar to the original one. A less restrictive set of constraints may lead to a generation of a larger number of problems, but the search process might take up more time.<\/p>\n<p>The tool performs a brute force search over all possible instantiations of the holes in the template and validates the correctness of each instantiation by doing random testing on free variables of the problem.

In this demo, we take a list of vocabulary words to test on, and then generate sentence completion questions that each use a desired vocabulary word. For example, for the vocabulary word \u201c<span style=\"color: #ff00ff;\">flouted<\/span>,\u201d it might generate:<\/p>\n<pre><span style=\"color: #ff00ff;\">But there were rules, and purists irritably noted when they were __________.<\/span><\/pre>\n<pre><span style=\"color: #ff00ff;\">a) installed<\/span><\/pre>\n<pre><span style=\"color: #ff00ff;\">b) trapped<\/span><\/pre>\n<pre><span style=\"color: #ff00ff;\">c) broached<\/span><\/pre>\n<pre><span style=\"color: #ff00ff;\">d) flouted<\/span><\/pre>\n<pre><span style=\"color: #ff00ff;\">e) fortified<\/span><\/pre>\n<p>To do this, the program first selects a vocabulary word, and then selects a sentence that uses the word from a database of over 2 million newspaper sentences. Since these sentences are chosen from published newspaper text, they illustrate a correct usage of the target word. To generate alternates or decoys, we analyze the sentence to determine the way in which the target word has been used. For example, in the sentence \u201cHe cleans his room every day, and it is always very orderly,\u201d the word \u201corderly\u201d is used as an adjective. But in the sentence \u201cThe general asked his orderly for coffee,\u201d it is used as a noun. Once the specific linguistic usage of a word has been determined, the program selects alternates from amongst other words that are commonly used in the same way, and presents the question for a teacher to accept or reject.<\/p>\n<p>In the past, generating sentence completion questions was a time consuming process requiring a great deal of thought to construct a good carrier sentence, and then to think up the alternates. With our technology, it takes just a few seconds to judge whether a question is acceptable, and a very large variety of questions can be generated.<\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/li>\n\t\t\t\t\t\t<li class=\"m-0\">\n\t\t\t<h4 class=\"accordion-header\">\n\t\t\t\t<button\n\t\t\t\t\tclass=\"btn btn-collapse m-0\"\n\t\t\t\t\ttype=\"button\"\n\t\t\t\t\tdata-mount=\"collapse\"\n\t\t\t\t\tdata-target=\"#collapse-6\"\n\t\t\t\t\taria-expanded=\"false\"\n\t\t\t\t\taria-controls=\"collapse-6\">\n\t\tLogic Problems\t\t\t\t<\/button>\n\t\t\t<\/h4>\n\t\t\t<div class=\"collapse\" id=\"collapse-6\">\n\t\t\t\t<div class=\"accordion-body\">\n\t\t\t\t\t\t\t\t\t\t<p>Natural deduction, which is a method for establishing validity of propositional type arguments, helps develop important reasoning skills and is thus a key ingredient in a course on introductory logic.
