Computational thinking (CT) is regarded as a valuable skill set for the students of the 21st century, fostering problem-solving skills applicable to academic disciplines and everyday problems. Assessing CT involves evaluating the development of its concepts, practices, and perspectives. However, establishing comprehensive and validated assessments...

Computational Thinking (CT), a problem-solving mental activity primarily dependent on abstraction, is regarded as a critical skill set for 21st-century students. Recent academic debates have led to a general agreement about the definition of Computational Thinking and the broad set of knowledge and skills that encloses, which is categorized into co...

Computational thinking (CT) refers to a universally applicable problem-solving skill set that involves expressing problems and their solutions in a way that an information-processing agent, such as a human, a machine, or a combination of both, can efficiently execute. Lately, there has been an increase of researchers suggesting that we must place C...

Computational thinking (CT) is broadly recognised as a set of problem-solving methods that involve expressing problems and their solutions in ways that enable their computer-mediated representation across a variety of fields. Nowadays, it is argued that CT needs to be expanded towards new pathways that establish a less individualistic and more soci...

Presently, computational thinking (CT) is considered necessary for adapting to the future. Concurrently, the COVID-19 pandemic has accentuated the demand for strengthening Environmental Education as a means to improve sustainability and stimulate environmental protection and public health. Having in mind that CT does not concern only technocrats bu...

In the modern digital era, the impressive development of mobile technologies has entailed the reformation of orientations, dispositions and stances in education, changing the dominant approaches to learning. In this article, we introduce the novel idea of the synergistic development of computational thinking skills and environmental awareness in th...

Computational thinking (CT) is an essential skill for students in the twenty-first century, constituting a set of universally applicable problem-solving strategies. While CT models emphasize the importance of testing and debugging as a fundamental CT practice, few studies have explicitly addressed its application for primary school students. This s...

Although a consensus on the definition of computational thinking (CT) has yet to be achieved, teaching resources and associated reforms of curricula encapsulating CT are in use. As such, the assessment of these efforts is essential in order to successfully introduce CT into curricula. This chapter conducts a literature review of recent studies on C...

This chapter focuses on the "unplugged" approach for teaching computational thinking (CT), that is, teaching without the use of computers or digital equipment. After a short discussion of the different definitions of CT, the chapter presents the most well-known tools and methodologies of unplugged philosophy, with a connection to CT concepts. The c...

The present paper presents the planning, implementation, observation and analysis of both quantitative and qualitative data of a participatory action research, aiming to study the potential role, value and uses of MOOCs in secondary education. Within the context of this research, a computer programming hybrid MOOC (named PROG15) which combined aspe...

Computational thinking (CT) is an essential skill for students in the 21st century, providing a set of problem-solving methods that involve formulating problems and solutions in a form that can be carried out by an information-processing agent across a variety of fields. In addition, research shows that the integration of CT in education has the po...

Το ενδιαφέρον για την Υπολογιστική Σκέψη (ΥΣ) αυξάνεται παγκοσμίως τα τελευταία χρόνια. Παρότι δημιουργείται υλικό για την ανάπτυξή της και προτείνονται προσεγγίσεις για την αξιολόγησή της, δεν υπάρχει ακόμα κοινά αποδεκτός ορισμός. Η αξιολόγηση της ΥΣ αποτελεί απαραίτητη προϋπόθεση για την επιτυχή εισαγωγή της σε προγράμματα σπουδών. Το άρθρο αυτό...

Η Υπολογιστική Σκέψη (Computational Thinking), μια νοητική δραστηριότητα που σχετίζεται με την επίλυση προβλημάτων (χωρίς να περιορίζεται σ’ αυτή) και έχει ως θεμελιώδη λίθο τη διαδικασία της αφαίρεσης (abstraction) για την αντιμετώπιση της πολυπλοκότητας, θεωρείται ως ένα απαραίτητο σύνολο δεξιοτήτων για τον μαθητή του 21ου αιώνα. Ο πρώτος ορισμός...

Η Υπολογιστική Σκέψη (ΥΣ) αποτελεί μια νοητική δραστηριότητα που σχετίζεται με την επίλυση προβλημάτων, βασιζόμενη στην αφαίρεση, την αποσύνθεση του προβλήματος, τον αλγοριθμικό τρόπο σκέψης και τη γενίκευση. Η επίτευξη σχετικής συναίνεσης ως προς το περιεχόμενο του όρου ήταν αποτέλεσμα επιστημονικών συζητήσεων που έλαβαν χώρα κατά την τελευταία δε...

The main purpose of this study was to investigate and compare the attitudes of freshmen and senior students of the Department of Primary Education, University of Thessaly, Greece, towards Information and Communications Technology (ICT) in Education. Moreover, this study explored the possible existence of correlations between the variables of the at...

This chapter investigates how educational software can affect critical thinking skills in primary education. To this end, we present a study which aimed to examine the impact of digital material for teaching Informatics in Primary Education considering exploratory, constructive and collaborative teaching approaches with the aim of acquiring problem...

This research focuses on the difficulties facing the students of tertiary education in the use of spreadsheets, as well as the errors commonly made. The research participants were students of the Technological Institute (T.E.I.) of Larissa, who worked in applications related to Management Information Systems. The students were asked to record the d...

In this paper we present the model-checking module of decision-making models in the frame of ModelsCreator, an educational modelling environment. The model-checking module aims to assist young students to construct qualitative models for decision-making problems solving. We specify the decision-making models that may be built and we explain the mod...

Στην εργασία αυτή παρουσιάζεται ένα ολοκληρωμένο περιβάλλον (το οποίο καλείται «Αλγοριθμική & Προγραμματισμός»), που στοχεύει στην υποστήριξη της διδασκαλίας του προγραμματισμού σε εισαγωγικό επίπεδο κάνοντας χρήση πολλαπλών μορφών ανα- παράστασης ενός προγράμματος. Αυτό το περιβάλλον έχει οικοδομηθεί γύρω από ένα σύνολο δραστηριοτήτων εκμάθησης βα...

Logic reasoning presents notable difficulties for young children. This paper presents Logic Model Creator (LMC), a new environment that supports build- ing and exploration of intuitive visual representation of logic models by young chil- dren. LMC logic models are structured as hypothesis, decision and / or counter deci- sion components. These mode...

This paper presents the main characteristics of Logic Models Creator (LMC). LMC is a new educational environment for young students to build and explore logic models in graphical form. LMC allows visual representation of logic models using IF/THEN/ELSE constructs. In this paper we provide an overview of LMC architecture and discuss briefly an examp...
