For decades, educators have relied on readability metrics that tend to oversimplify dimensions of text difficulty. This study examines the potential of applying advanced artificial intelligence methods to the educational problem of assessing text difficulty. The combination of hierarchical machine learning and natural language processing (NLP) is…

One of the main aims of Core Maths qualifications when they were introduced into the post-16 curriculum in 2014 was to help students develop their understanding of maths and its application to different subject areas, particularly in relation to further study (e.g., higher education). In this article, we explore whether Core Maths is fulfilling…

This is the technical appendix for the report, "Adapting to Changes in California's English Learner Population," which examines how the size and composition of the English Learner (EL) population has changed and whether services, program offerings, and learning trajectories have evolved in response to these changes. This appendix…

This study developed a typology of eight heterogeneous types of baby boomer entrepreneurs and extended the occupational choice model regarding driving factors for entrepreneurialism in this population. The study relied on monthly USA Current Population Survey data across 11 years (2006-2016), and using 2-sample t-tests and multilevel mixed-effects…

Ariadne is a touch-based program for the learning of homotopies of paths, without the use of formalism, by building mental models. Using Ariadne, the user can construct points, paths by dragging points and homotopies by dragging paths as well as compute winding numbers of paths, all on a variety of surfaces, through touch gestures. Ariadne…

Developing tools to support students and learning in a traditional or online setting is a significant task in today's educational environment. The initial steps toward enabling such technologies using machine learning techniques focused on predicting the student's performance in terms of the achieved grades. However, these approaches do not…

In this paper, we take a semiotic/dialogic approach to investigate how a group of UK 12-13-year-old students work with hierarchical defining and classifying quadrilaterals. Through qualitatively analysing students' decision-making processes, we found that the students' decision-making processes are interpreted as transforming their…

The objective of this paper is to analyze the impact of the factors that stimulate inspiration in the design process. An empirical study is proposed in this paper. Three factors were summarized, including knowledge, knowledge relations and innovative strategies. Representations of these three factors that were extracted from the international…

'Emotional reactivity' (ER) is an important construct in the analysis of individual temperamental differences, and has accounted for significant variance in studies with respect to its definition. Between 1920 and 2015, the meaning of ER has varied from physiology of emotional reactions, to stress, depression, and as a sub-type of empathy. This…

Past research has shown a discrepancy in young infants' use of height information in occlusion and containment events--a pattern typically accounted for by event categorization and rule learning. Broadening these theories, the present experiment examined the role of comparison in young infants' reasoning about physical events. We rotated a typical…

This study explores classification consistency and accuracy for mixed-format tests using real and simulated data. In particular, the current study compares six methods of estimating classification consistency and accuracy for seven mixed-format tests. The relative performance of the estimation methods is evaluated using simulated data. Study…

Although much research has been conducted on the psychometric properties of cognitive diagnostic models, they are only recently being used in operational settings to provide results to examinees and other stakeholders. Using this newer class of models in practice comes with a fresh challenge for diagnostic assessment developers: effectively…

When exposed to principal components analysis for the first time, students can sometimes miss the primary purpose of the analysis. Often the focus is solely on data reduction and what to do after the dimensions of the data have been reduced is ignored. The datasets discussed here can be used as an in-class example, a homework assignment, or a…

In the past decades, there has been a surge in interest in the study of language complexity in second language (L2) research. In this article we provide an overview of current theoretical and methodological practices in L2 complexity research, while simultaneously framing these within the broader scientific interest into the notion of complexity.…

This paper discusses a poetry translation, Love & Misadventure by Lang Leav into Indonesian translated by Aan Mansyur. The purpose of this study is to determine how the translator considers the translation techniques used to translate the poem into the target language and its impact of the translation quality in terms of accuracy and…
