Automated scoring of free drawings or images as responses has yet to be used in large-scale assessments of student achievement. In this study, we propose artificial neural networks to classify these types of graphical responses from a TIMSS 2019 item. We are comparing classification accuracy of convolutional and feed-forward approaches. Our…

One of the most elementary concepts in freshmen Electrical Engineering subject comprises the Resistance-Inductance-Capacitance (RLC) circuit fundamentals, that is, their time and frequency domain responses. For a beginner, generally, it is difficult to understand and appreciate the step and the frequency responses, particularly the resonance. This…

TIMSS (Trends in International Mathematics and Science Study) is a long-standing international assessment of mathematics and science at the fourth and eighth grades that has been collecting trend data every four years since 1995. About 70 countries use TIMSS trend data for monitoring the effectiveness of their education systems in a global…

Item Response Theory (IRT) is a ubiquitous model for understanding humans based on their responses to questions, used in fields as diverse as education, medicine and psychology. Large modern datasets offer opportunities to capture more nuances in human behavior, potentially improving test scoring and better informing public policy. Yet larger…

When dealing with missing responses, two types of omissions can be discerned: items can be skipped or not reached by the test taker. When the occurrence of these omissions is related to the proficiency process the missingness is nonignorable. The purpose of this article is to present a tree-based IRT framework for modeling responses and omissions…

Evaluative reactions to language stimuli are presumably dynamic events, constantly changing through time as the signal unfolds, yet the tools we usually use to capture these reactions provide us with only a snapshot of this process by recording reactions at a single point in time. This paper outlines and evaluates a new methodology which employs…

Automatic coding of short text responses opens new doors in assessment. We implemented and integrated baseline methods of natural language processing and statistical modelling by means of software components that are available under open licenses. The accuracy of automatic text coding is demonstrated by using data collected in the "Programme…

Teaching with a classroom feedback system can benefit both teaching and learning practices of interactivity. In this paper, we propose a dual-channel classroom feedback system integrated with a back-end e-Learning system. The system consists of learning agents running on the students' computers and a teaching agent running on the instructor's…

Research in the study of students' writing concludes that vocabulary use is a key variable in determining the holistic quality of the writing. In the present study, 77 writing samples from a mixed group of Grade 3 children were analyzed for features of linguistic diversity using public domain vocabulary-profiling software. The writing was also…

The methodology used in this study was action-research and the considered activity is been applied successfully for at least five years to undergraduate and to master classes for Industrial Engineering students in Brazil. It showed a significant result in both cases, providing the basis for the deepening in the subject in further lessons.…

For many people, mobile phones are a part of modern life. Although the purpose of this technology revolves around language and communication, its application to language learning still appears to be underutilized. This is changing, as the widespread use of this handheld technology offers numerous opportunities to use functions that are ideal for…

The current study investigated the relative effects of Before and After relational cues on temporal order judgments. In Experiment 1, participants (N = 20) were exposed to a 5-phase temporal relational responding task. Participants observed a sequence of 2 familiar shapes and then completed either a Before or an After statement to describe the…

These proceedings contain the papers of the 12th International Conference on Mobile Learning 2016, which was organized by the International Association for Development of the Information Society, in Vilamoura, Algarve, Portugal, April 9-11, 2016. The Mobile Learning 2016 Conference seeks to provide a forum for the presentation and discussion of…
