Computational thinking (CT) has been introduced in primary schools worldwide. However, rich classroom-based evidence and research on how to assess and support students’ CT through programming are particularly scarce. This empirical study investigates 4th grade students’ (N = 57) CT in a comparatively comprehensive and fine-grained manner by assessing their Scratch projects (N = 325) with a framework that was revised from previous studies to aim towards enhancing CT. The results demonstrate in detail the various coding patterns and code constructs the students programmed in assorted projects throughout a programming course and the extent to which they had conceptual encounters with CT. Notably, the projects indicated CT diversely, and the students altogether encountered dissimilar areas in CT. To target the acquisition of CT broadly, manifold programming activities are necessary to introduce in the classroom. Furthermore, we discuss the possibilities of applying the assessment framework employed herein to support CT education through Scratch in classrooms.
In recent years, Artificial Intelligence (AI) has shown significant progress and its potential is growing. An application area of AI is Natural Language Processing (NLP). Voice assistants incorporate AI by using cloud computing and can communicate with the users in natural language. Voice assistants are easy to use and thus there are millions of devices that incorporates them in households nowadays. Most common devices with voice assistants are smart speakers and they have just started to be used in schools and universities. The purpose of this paper is to study how voice assistants and smart speakers are used in everyday life and whether there is potential in order for them to be used for educational purposes.
Connecting theory and practice in teaching is sometimes difficult, as it requires expensive or delicate equipment, thus limiting the teacher to giving demonstrations in which students are passive participants. Numerical mathematics, as an applied discipline, should be taught on real world examples. By using inexpensive Arduino hardware, we can create simple experiments that are easily reproduced by students. Furthermore, the experiments generate tangible data, which can be processed numerically. The choice of the software used for numerical processing is also an important issue. We present several exercises in numerical mathematics that are based on experiments in electrical engineering with Arduino, and show how to turn them into motivational examples. We also present our experiences in teaching using the developed exercises, as well as some important points and conclusions, which stem from discussions with the participating students and teachers.
This work presents a systematic review whose objective was to identify heuristics applicable to the evaluation of the usability of educational games. Heuristics are usability engineering methods that aim to detect problems in the use of a system during its development and / or when its interface is in interaction with the user. Therefore, applying heuristics is an essential part of developing digital educational games. Search sources were articles available in all the databases present in the Capes / MEC / Brazil periodicals portal, in the available languages. The descriptors adopted were "educational games", "heuristic" and "usability" in Boolean search in titles, abstracts and keywords, with AND operator, for publications starting in 2014. The inclusion criteria were: (a) articles with a clear description of the methodology used in the usability analysis; (b) studies presenting primary data and (c) articles whose focus corresponds to the investigated question. Two examiners conducted the searches in the databases and a third the evaluation and general review of the data. Initially, 93 articles were identified, of which 19 were repeated, 5 were literature reviews. Of the 69 that remained, 57 were elected as not eligible with only 12 selected for full studies, of which 6 entered the final review. With this review we can deduce that the field of heuristics and usability for educational games is still little explored, with few specific evaluations validated or in the process of validation, requiring greater investment in the area. Through this review, we found at least one heuristic that meets the usability evaluation of educational software: Game User Experience Satisfaction Scale (GUESS).
Amount of educational data has been constantly increasing for years in all domains and kinds of education (formal or informal) and educational activities (teaching, learning, assessment, use of social media and collaboration and so on). Accordingly, Learning Analytics (LA) become a powerful mechanism for supporting learners, instructors, teachers, learning system designers and developers to better understand educational processes and predict learners' needs and performances. In this paper, we analyze the important dimensions and objectives of LA, application possibilities and some challenges to the beneficial exploitation of educational data. The required skills and capabilities that make meaningful use of LA techniques and technologies in this domain are considered and identified. Presented findings can act as a valuable guide for setting up LA services in support of educational practice. Also, they can be used as learner guidance, in quality assurance, curriculum development, and in improving learning process effectiveness and efficiency. Finally, this paper proposes the unavoidable constraints that affect LA technologies in education.
The European Commission Science Hub has been promoting Computational Thinking (CT) as an important 21st century skill or competence. However, "despite the high interest in developing computational thinking among schoolchildren and the large public and private investment in CT initiatives, there are a number of issues and challenges for the integration of CT in the school curricula". On the other hand, the Digital Competence (DC) Framework 2.0 (DigCom) is promoted in the same European Commission Science Hub portal. It shows that both topics have many things in common. Thus, there is the need of research on the relationship between CT and digital competence.
The goal of this paper is to analyse and discuss the relationship between DC and CT, and to help educators as well as educational policy makers to make informed decisions about how CT and DC can be included in their local institutions. We begin by defining DC and CT and then discuss the current state of both phenomena in education in multiple countries in Europe. By analysing official documents, we try to find the underlying commonness in both DC and CT, and discover all possible connections between them. Possible interconnections between the component groups of approaches are presented in Fig.
One of the main goals of many educational courses at various colleges, especially those which focus on applied economics and management, is the development of students' entrepreneurship skills. It is usually accomplished through various project-oriented tasks. The development of the students' entrepreneurship skills is also the primary objective of the E-commerce course offered by our Faculty of Economics. This course combines theoretical knowledge and practical skills. Students work on a number of practical exercises with the aim to create a functional e-shop. They have to look for business opportunities, understand economic processes, work within a team, and be able to promote their ideas, strategies, and procedures. Finally, yet most importantly, they must not be afraid to present and defend their solutions. This study examines whether and to what extent this approach contributes to the development of skills which are usually associated with entrepreneurship. The exploration was performed based on students' evaluation. Means-end chain model and hierarchical value map approach were chosen as a research method. The results of this research show that entrepreneurship skills are being developed except for a motivation of students to accept a risky business competitive environment. However, the propensity to take risk is one of the basic traits of successful entrepreneurs. Our future effort will aim therefore at modifying our educational content. Greater emphasis will be placed on how to teach students to accept competitive environment which is risky and mostly unpredictable.
This work is part of a research project whose main objective is to understand the impact that the use of Information and Communication Technology (ICT) has on the teaching and learning process on the subject of Physics. We will show that, with the use of a storm simulator, physics students improve their learning process on one hand they understand storm phenomenon, and on the other hand they assimilate in better way physics ideas. Computer technology is a positive supplement to bridge the gap between education and the technological world in which we live. Computer-assisted technologies at the university offer students a great access to information, an eager motivation to learn, a jump-start on marketable job skills and an enhanced quality of class work.
This work investigates the effect of computer use in the memory process in young and adults under the Perceptual and Memory experimental conditions. The memory condition involved the phases acquisition of information and recovery, on time intervals (2 min, 24 hours and 1 week) on situations of pre and post-test (before and after the participants took part on a Basic Computing course), in which the participants studied the map of Brazil during 7 minutes and the estimates of different areas of Brazilian states were performed according to the magnitude estimation method, without the presence of the map. On the Perceptual condition, the estimates were made in the presence of the Brazilian map. The study made possible to verify that the use of a computer, as a new activity enables a differentiation on the memory process in relation to the different experimental conditions proposed and to the time intervals used between acquisition, processing and information recovery, showing that the use of a computer as a pedagogical tool may promote the improvement of the memory process in academic activities.
Many factors influence education nowadays. Educational institutions are faced with budget cuttings, outdated IT, data security management and the willingness to integrate remote learning at home. Virtualization technologies provide innovative solutions to the problems.
The paper presents an original educational infrastructure using virtualization technologies implemented in a training process at Kaunas University of Technology. This infrastructure allows university students and staff to access virtual desktops and applications via Web, both in computer classes at the University, and for self-working at home. This paper introduces virtualization technologies of the implemented infrastructure highlighting the benefits, outlines functions of the infrastructure and presents research experiments of network load monitoring that have been performed to find out problems of the infrastructure.
