How Can Web Lessons Be Taught to Reduce Screen Fatigue, Motivational, and Concentration Problems in Different Disciplines?

However, students' perception of engagement strategies, screen fatigue, difficulties motivating themselves and problems with concentrating on web lessons should be also taken into account. The goal of this research is to find out how students rate the importance of engagement strategies in web lessons and how the ratings differ between disciplines. Also, the study aims to investigate how concentration difficulties, students' motivational problems and screen fatigue are connected to student engagement strategies in web lessons. To achieve that goal, 430 students of the Faculty of Sciences and Technology and the Faculty of Social Sciences at the University of Tartu were surveyed and multivariate analyses of variance and correlational analyses were co...

Automation of assessment and feedback in IT teaching from the teaching staff perspective

As the number of entrants continues to grow year-by-year, the load on teaching staff also increases. Automation of teaching activities can be used to alleviate the high workload resulting from courses with hundreds of students. The aim of this study is to ascertain the processes that could be automated in the context of assessment and feedback. To gather ideas, eight one-hour mini-group interviews were conducted at the Institute of Computer Science, the University of Tartu, with 17 faculty members responsible for teaching IT courses. A qualitative approach was used for classifying the proposed ideas related to the automated assessment and automated feedback. Five main categories connected to automated assessment emerged from analyzing the codes generated based on the interviews using qualitative content analysis: use of automated assessment, instructor-related topics, negative e...

Self- and Automated Assessment in Programming MOOCs

We have used two kinds of automated assessment: quizzes in Moodle and programming exercises with automated feedback provided by Moodle plug-in VPL. We also used two kinds of self-assessment: (1) self-assessment questions with feedback and explanations for every answer and (2) so-called “troubleshooters” for every programming exercise, which contain answers to the questions that can arise during the solution of a given exercise. This paper describes our experience in the creation of quizzes, programming exercises, and tests for automated feedback, self-assessment questions, and troubleshooters. The paper discusses the problems and questions that arose during this process and presents learners’ opinions about self- and automated assessment. The paper concludes with a discussion of the impact of self- and automated assessment in MOOCs, describes the work of MOOC organizers and the behaviour of learners in MOOCs.

Local and External Stakeholders Affecting Educational Change during the Coronavirus Pandemic: A Study of Facebook Messages in Estonia

Education Sciences, 2021

Education worldwide was affected by the coronavirus pandemic when many countries, including Eston... more Education worldwide was affected by the coronavirus pandemic when many countries, including Estonia, had to switch to distance learning. It was an unexpected change in education and required a response from relevant stakeholders. This study aims to understand the activities of different stakeholders as revealed in the messages of the Facebook group ‘Homeschooling with technology’ from 6 March to 26 April 2020. A mixed method study design was used, including quantitative and qualitative content analysis of 872 messages posted by members of the Facebook group, which were divided into eight role groups. Teachers, educational technologists, principals and parents represented local stakeholders while external stakeholders included members from government institutions, supporters, teacher educators and members with other roles. The analysis covered activeness of each role group, emotional expressions, speech acts and topics represented in messages. The results indicate that educational te...

Our main didactical principle has been that all the necessary decisions and calculations at each solution step should be made by the student, and the program should be able to understand the mistakes. This paper describes the design of our Action-Object-Input dialogue and different input modes as an instrument to communicate three natural attributes of the step: choice of conversion rule, operands and result.
