Crowdsourcing Multiple Choice Science Questions
We present a novel method for obtaining high-quality, domain-targeted
multiple choice questions from crowd workers. Generating these questions can be
difficult without trading away originality, relevance or diversity in the
answer options. Our method addresses these problems by leveraging a large
corpus of domain-specific text and a small set of existing questions. It
produces model suggestions for document selection and answer distractor choice
which aid the human question generation process. With this method we have
assembled SciQ, a dataset of 13.7K multiple choice science exam questions
(Dataset available at http://allenai.org/data.html). We demonstrate that the
method produces in-domain questions by providing an analysis of this new
dataset and by showing that humans cannot distinguish the crowdsourced
questions from original questions. When using SciQ as additional training data
to existing questions, we observe accuracy improvements on real science exams.Comment: accepted for the Workshop on Noisy User-generated Text (W-NUT) 201
STARC: Structured Annotations for Reading Comprehension
We present STARC (Structured Annotations for Reading Comprehension), a new
annotation framework for assessing reading comprehension with multiple choice
questions. Our framework introduces a principled structure for the answer
choices and ties them to textual span annotations. The framework is implemented
in OneStopQA, a new high-quality dataset for evaluation and analysis of reading
comprehension in English. We use this dataset to demonstrate that STARC can be
leveraged for a key new application for the development of SAT-like reading
comprehension materials: automatic annotation quality probing via span ablation
experiments. We further show that it enables in-depth analyses and comparisons
between machine and human reading comprehension behavior, including error
distributions and guessing ability. Our experiments also reveal that the
standard multiple choice dataset in NLP, RACE, is limited in its ability to
measure reading comprehension. 47% of its questions can be guessed by machines
without accessing the passage, and 18% are unanimously judged by humans as not
having a unique correct answer. OneStopQA provides an alternative test set for
reading comprehension which alleviates these shortcomings and has a
substantially higher human ceiling performance.Comment: ACL 2020. OneStopQA dataset, STARC guidelines and human experiments

Using item response theory to explore the psychometric properties of extended matching questions examination in undergraduate medical education
BACKGROUND:
As assessment has been shown to direct learning, it is critical that the examinations developed to test clinical competence in medical undergraduates are valid and reliable. The use of extended matching questions (EMQ) has been advocated to overcome some of the criticisms of using multiple-choice questions to test factual and applied knowledge.
METHODS:
We analysed the results from the Extended Matching Questions Examination taken by 4th year undergraduate medical students in the academic year 2001 to 2002. Rasch analysis was used to examine whether the set of questions used in the examination mapped on to a unidimensional scale, the degree of difficulty of questions within and between the various medical and surgical specialties and the pattern of responses within individual questions to assess the impact of the distractor options.
RESULTS:
Analysis of a subset of items and of the full examination demonstrated internal construct validity and the absence of bias on the majority of questions. Three main patterns of response selection were identified.
CONCLUSION:
Modern psychometric methods based upon the work of Rasch provide a useful approach to the calibration and analysis of EMQ undergraduate medical assessments. The approach allows for a formal test of the unidimensionality of the questions and thus the validity of the summed score. Given the metric calibration which follows fit to the model, it also allows for the establishment of items banks to facilitate continuity and equity in exam standards
Learning to Reuse Distractors to support Multiple Choice Question Generation in Education
Multiple choice questions (MCQs) are widely used in digital learning systems,
as they allow for automating the assessment process. However, due to the
increased digital literacy of students and the advent of social media
platforms, MCQ tests are widely shared online, and teachers are continuously
challenged to create new questions, which is an expensive and time-consuming
task. A particularly sensitive aspect of MCQ creation is to devise relevant
distractors, i.e., wrong answers that are not easily identifiable as being
wrong. This paper studies how a large existing set of manually created answers
and distractors for questions over a variety of domains, subjects, and
languages can be leveraged to help teachers in creating new MCQs, by the smart
reuse of existing distractors. We built several data-driven models based on
context-aware question and distractor representations, and compared them with
static feature-based models. The proposed models are evaluated with automated
metrics and in a realistic user test with teachers. Both automatic and human
evaluations indicate that context-aware models consistently outperform a static
feature-based approach. For our best-performing context-aware model, on average
3 distractors out of the 10 shown to teachers were rated as high-quality
distractors. We create a performance benchmark, and make it public, to enable
comparison between different approaches and to introduce a more standardized
evaluation of the task. The benchmark contains a test of 298 educational
questions covering multiple subjects & languages and a 77k multilingual pool of
distractor vocabulary for future research.Comment: 24 pages and 4 figures Accepted for publication in IEEE Transactions

Item statistics derived from three-option versions of multiple-choice questions are usually as robust as four- or five-option versions: implications for exam design.
Different versions of multiple-choice exams were administered to an undergraduate class in human physiology as part of normal testing in the classroom. The goal was to evaluate whether the number of options (possible answers) per question influenced the effectiveness of this assessment. Three exams (each with three versions) were given to each of two sections during an academic quarter. All versions were equally long, with 30 questions: 10 questions with 3 options, 10 questions with 4, and 10 questions with 5 (always one correct answer plus distractors). Each question appeared in all three versions of an exam, with a different number of options in each version (three, four, or five). Discrimination (point biserial and upper-lower discrimination indexes) and difficulty were evaluated for each question. There was a small increase in difficulty (a lower average score on a question) when more options were provided. The upper-lower discrimination index indicated a small improvement in assessment of student learning with more options, although the point biserial did not. The total length of a question (number of words) was associated with a small increase in discrimination and difficulty, independent of the number of options. Quantitative questions were more likely to show an increase in discrimination with more options than nonquantitative questions, but this effect was very small. Therefore, for these testing conditions, there appears to be little advantage in providing more than three options per multiple-choice question, and there are disadvantages, such as needing more time for an exam
