Measuring student’s proficiency in MOOCs: Multiple attempts extensions for the Rasch model
Popularity of online courses with open access and unlimited student participation, the so-called massive open online courses (MOOCs), has been growing intensively. Students, professors, and universities have an interest in accurate measures of students' proficiency in MOOCs. However, these measurements face several challenges: (a) assessments are dynamic: items can be added, removed or replaced by a course author at any time; (b) students may be allowed to make several attempts within one assessment; (c) assessments may include an insufficient number of items for accurate individual-level conclusions. Therefore, common psychometric models and techniques of Classical Test Theory (CTT) and Item Response Theory (IRT) do not serve perfectly to measure proficiency. In this study we try to cover this gap and propose cross-classification multilevel logistic extensions of the common IRT model, the Rasch model, aimed at improving the assessment of the student's proficiency by modeling the effect of attempts and by involving non-assessment data such as student's interaction with video lectures and practical tasks. We illustrate these extensions on the logged data from one MOOC and check the quality using a cross-validation procedure on three MOOCs. We found that (a) the performance changes over attempts depend on the student: whereas for some students performance ameliorates, for other students, the performance might deteriorate; (b) similarly, the change over attempts varies over items; (c) student's activity with video lectures and practical tasks are significant predictors of response correctness in a sense of higher activity leads to higher chances of a correct response; (d) overall accuracy of prediction of student's item responses using the extensions is 6% higher than using the traditional Rasch model. In sum, our results show that the approach is an improvement in assessment procedures in MOOCs and could serve as an additional source for accurate conclusions on student's proficiency.
In this book Lee Rudolph brings together international contributors who combine psychological and mathematical perspectives to analyse how qualitative mathematics can be used to create models of social and psychological processes. Bridging the gap between the fields with an imaginative and stimulating collection of contributed chapters, the volume updates the current research on the subject, which until now has been rather limited, focussing largely on the use of statistics.
Qualitative Mathematics for the Social Sciences contains a variety of useful illustrative figures, introducing readers from the social sciences to the rich contribution that modern mathematics has made to our knowledge of logic, structures, and dynamic systems. A beguiling array of conceptual systems, topological models and fractals are discussed which transcend the application of statistics, and bring a fresh perspective to the study of social representations.
The wide selection of qualitative mathematical methodologies discussed in this volume will be hugely valuable to higher-level undergraduate and postgraduate students of psychology, sociology and mathematics. It will also be useful for researchers, academics and professionals from the social sciences who want a firmer grasp on the use of qualitative mathematics.
Management in Russia is as difficult to define as a profession as it is in other countries, and the question of what education is appropriate for a future manager is also difficult to define. Business schools in russia need to think more carefully about their curriculums and about what they should be preparing their students for.
Such crucial aspects of philosophical and psychological conception of scientific work of prominent domestic philosopher and psychologist Sergey Leonidovich Rubinstein as problems of Man and Personality, ontological basis of their essence and means of existence and self-realization are analyzed. Created by the scientists school consecutively developed his sophisticated and profound ideas, integrating separately elaborated aspects (abilities, needs, motivation, consciousness, self-consciousness, thinking as personality problems), widening the context of their researches. Rubinstein's approach due to his disciples and followers, due to the constructivism of his ideas itself holds a leading position in Russian psychology.
The paper addresses the questions of data science education of current importance. It aims to introduce and justify the framework that allows flexibly evaluate the processes of a data expedition and a digital media created during it. For these purposes, the authors explore features of digital media artefacts which are specific to data expeditions and are essential to accurate evaluation. The rubrics as a power but hardly formalizable evaluation method in application to digital media artefacts are also discussed. Moreover, the paper documents the experience of rubrics creation according to the suggested framework. The rubrics were successfully adopted to two data-driven journalism courses. The authors also formulate recommendations on data expedition evaluation which should take into consideration structural features of a data expedition, distinctive features of digital media, etc.
The article is concerned with results of content analysis of textbooks for high school in the area of social and human sciences. The author uses the typology of values introduced by S. Schwartz which consists of two value axes — “conservation — openness to change” and “selfassertion — caring about people and nature” — and describes values that underlie each subject area and then compares these values with results of mass surveys of the values of Russians.
The objective of this paper is to estimate the factors of intergeneration educational mobility in Russia and Soviet Union, that is to test the equality in accessing the continuation of education at the next level for children from different social groups (families with various levels of the family capital), estimated for different cohorts. The data source is Russian Longitudinal Monitoring Survey (RLMS-HSE) in 2006-11. There are panel data collected in 1994-2011. The sample is representative for Russia population as a whole. In 2006 there were some questions about respondent parents, that allow us to test if there is the dependence between educational level of respondent and some parameters of his/her parents, including their educational level, Communist Party membership and several other.
We estimated the model of probability to get the education of the given level depending on gender, age, nationality, characteristics of parents and birthplace for Russian people born in 1946-1990. Data about respondents' education are collected in 2006-11, about their parents - in 2006. The method of this model estimation is multinomial regression. The model was estimated for the pooled sample, as well as for three cohorts separately: born in 1946-60, 1961-75, 1976-90. It was found out that the family capital (first of all, the educational level of parents and urbanization level) represent an essential obstacle for educational opportunities of Russian high schools graduates. Regression estimation for the pooled sample demonstrates the significant level of dependence of respondents' education on that of their parents.
How are professors paid? Can the "best and brightest" be attracted to the academic profession? With universities facing international competition, which countries compensate their academics best, and which ones lag behind? Paying the Professoriate examines these questions and provides key insights and recommendations into the current state of the academic profession worldwide. Paying the Professoriate is the first comparative analysis of global faculty salaries, remuneration, and terms of employment. Offering an in-depth international comparison of academic salaries in twenty-eight countries across public, private, research, and non-research universities, chapter authors shed light on the conditions and expectations that shape the modern academic profession. The top researchers on the academic profession worldwide analyze common themes, trends, and the impact of these matters on academic quality and research productivity. In a world where higher education capacity is a key driver of national innovation and prosperity, and nations seek to fast-track their economic growth through expansion of higher education systems, policy makers and administrators increasingly seek answers about what actions they should be taking. Paying the Professoriate provides a much needed resource, illuminating the key issues and offering recommendations.
