Computational Thinking (CT) is crucial for the advancement of the STEM field, where there continues to be a lack of female representation. Teaching and learning (T/L) of CT should incorporate didactic strategies that aim to eliminate gender biases and integrate girls/women into this context. In response to the question, "What didactic strategies have been implemented in the T/L of CT in primary and secondary education?". A systematic review was conducted following a PRISMA protocol specifically designed for this review. The study analysed Didactic Strategies (DS) and examined whether they incorporated the so‐called "minimum actions" (MA) proposed in this article as a strategy to integrate females into CT. The findings revealed a limited number of studies that implemented these actions. In conclusion, there is an urgent need to continue developing DS that incorporate these MA to effectively integrate girls and women into CT, allowing them to play a central role in its advancement and development.

Introduction: With the increasing amount of research around Computational Thinking (CT) and endeavors introducing CT into curricula worldwide, assessing CT at all levels of formal education is of utmost importance to ensure that CT-related learning objectives are met. This has contributed to a progressive increase in the number of validated and reliable CT assessments for K-12, including primary school. Researchers and practitioners are thus required to choose among multiple instruments, often overlapping in their age validity. Methods: In this study, we compare the psychometric properties of two of these instruments: the Beginners' CT test (BCTt), developed for grades 1-6, and the competent CT test (cCTt), validated for grades 3-4. Classical Test Theory and ItemResponse Theory (IRT) were employed on data acquired from 575 students in grades 3-4 to compare the properties of the two instruments and refine the limits of their validity. Results: The findings (i) establish the detailed psychometric properties of the BCTt in grades 3-4 for the first time, and (ii) through a comparison with students from the same country, indicate that the cCTt should be preferred for grades 3-4 as the cCTt is able to discriminate between students of low and medium ability. Conversely, while the BCTt, which is easier, shows a ceiling effect, it is better suited to discriminate between students in the low ability range. For these grades, the BCTt can thus be employed as a screening mechanism to identify low ability students. Discussion: In addition to providing recomendations for use of these instruments, the findings highlight the importance of comparing the psychometric properties of existing assessments, so that researchers and practitioners, including teachers and policy makers involved in digital education curricular reforms, may take informed decisions when selecting assessments.

Este artículo presenta una investigación que ha medido el impacto causal de la intervención realizada en el marco del proyecto Escuela de Pensamiento Computacional, que el Ministerio de Educación y Formación Profesional de España inició en el curso académico 2018-2019. En concreto, se estudia si es posible mejorar el desarrollo de la competencia matemática a través de actividades de programación en 5º de Educación Primaria. El diseño de la investigación está basado en las lecciones aprendidas del proyecto ScratchMaths desarrollado por la University College London en Reino Unido. Se han usado dos grupos de estudiantes no equivalentes, grupo experimental y grupo de control, sin asignación aleatoria, con medición pre-test y post-test sobre la variable competencia matemática. Para ello, se ha contado con la participación de más de 3.700 estudiantes. Los resultados muestran que el alumnado del grupo experimental desarrolló en mayor medida esta competencia que el alumnado del grupo de control, apreciándose un impacto significativo y positivo. Con un tamaño del efecto de la intervención d=0,449 puede afirmarse que el proyecto logró el efecto pretendido sobre la competencia matemática. La generalización de experiencias de pensamiento computacional en el currículum podrá garantizar la mejora de la calidad de los procesos educativos This article presents an investigation that has measured the causal impact of the intervention carried out within the framework of the School of Computational Thinking project, launched by the Ministry of Education and Vocational Training of Spain in the 2018-2019 academic year. Specifically, it studies whether it is possible to improve the development of mathematical competence through programming activities in 5th grade of Primary Education. The research design are based on the lessons learned from the ScratchMaths project developed by University College London in the United Kingdom. Two groups of non-equivalent students have been used, the experimental group and the control group, without random assignment, with pre-test and post-test measurement on the mathematical competence variable. More than 3,700 students participated in the investigation. The results show that the students in the experimental group developed this competence to a greater extent than the students in the control group, with a significant and positive impact. Being the intervention effect size d=0.449, it can be stated that the project achieved the intended effect on mathematical competence. The generalization of computational thinking experiences in the curriculum can guarantee the improvement of the quality of the educational processes.

The use of Artificial Intelligence (AI) offers new and thriving opportunities, but introduces also new risks and ethical issues that should be dealt with. We argue that the introduction of AI contents at schools through practical, hands-on, projects is the way to go to educate conscientious and critical citizens of the future, to awaken vocations among youth people, as well as to foster students’ computational thinking skills. However, most existing programming platforms for education lack some of the required educational features to develop a complete understanding of AI. In this paper we present LearningML, a new platform aimed at learning supervised Machine Learning (ML), one of the most successful AI techniques that is in the basis of almost every current AI application. This work describes the main functionalities of the tool and discusses some decisions taken during its design. For its conception, we have taken into account lessons learned from the research literature on introducing AI in school and from the analysis of other educational tools built with the aim to allow learners to use ML. We offer as well some promising results obtained after a preliminary testing pilot workshop. Finally, the next steps in the development of LearningML are presented, focused on the face and instructional validation of the tool. El uso de Inteligencia Artificial (IA) ofrece nuevas y prósperas oportunidades, pero también introduce nuevos riesgos y cuestiones éticas que deben abordarse. Sostenemos que la introducción de contenidos de inteligencia artificial en las escuelas a través de proyectos prácticos es el camino a seguir para educar ciudadanos conscientes y críticos, para despertar vocaciones entre los jóvenes, y para fomentar las habilidades de pensamiento computacional de los estudiantes. Sin embargo, la mayoría de las plataformas educativas de programación existentes carecen de algunas características necesarias para desarrollar proyectos completos de IA y, en consecuencia, se requieren nuevas herramientas. En este artículo presentamos LearningML, una nueva plataforma dirigida al Aprendizaje Automático (ML) supervisado, una de las técnicas de IA más exitosas que se encuentra en la base de casi todas las aplicaciones actuales de IA. Este trabajo describe las principales funcionalidades de la herramienta y discute algunas decisiones tomadas durante su diseño, para el que hemos tenido en cuenta las lecciones aprendidas al revisar trabajos anteriores realizados para introducir la IA en la escuela y el análisis de otras soluciones destinada al aprendizaje de ML. Analizamos, además, los prometedores resultados que hemos obtenido en la realización de un taller preliminar para probar la eficacia de la herramienta. Por último, presentamos los próximos pasos en el desarrollo de LearningML, que se centran en la validación, tanto aparente como instruccional, de la herramienta

Far-reaching technological changes are shaping our society and the ways in which we work. A key 21st-century skill for taking advantage of those changes may be computational thinking (CT). CT aims at enabling humans to carry out more effective problem solving by utilizing concepts of computing and computer technology. For a successful integration of CT into curricula, however, it is important to take assessment into account. We review two instruments that capture CT: the Computational Thinkig Test (CTt), a performance test, and the Computational Thinking Scales (CTS), that relies on self-assessment. We have adapted both instruments from English to German. Using a sample of 202 upper-secondary students from Switzerland, we provide further evidence on the validity of both instruments. To this end, we apply item response theory and confirmatory factor analysis. Furthermore, we evaluate the relationship between CTt and CTS. Both instruments show good properties and may be suitable for assessing CT in German-speaking countries at the secondary level. [ABSTRACT FROM AUTHOR]

Una de las barreras de entrada de la programación informática en las escuelas es la falta de herramientas que ayuden al profesorado en la evaluación de los proyectos del alumnado. Con el objetivo de resolver esta situación, este artículo presenta Dr. Scratch, una aplicación web que permite a educadores y alumnos analizar automáticamente proyectos Scratch, el lenguaje de programación más utilizado globalmente en educación primaria y secundaria, para comprobar si se han programado correctamente, aprender de sus errores y recibir retroalimentación para mejorar su código y desarrollar el Pensamiento Computacional (PC). Uno de los objetivos de Dr. Scratch, además de ayudar al docente en las tareas de evaluación, es ser un estímulo para animar a los aprendices a seguir mejorando sus habilidades de programación. Para comprobar la efectividad de la herramienta en este sentido, se organizaron talleres en 8 colegios con alumnos de entre 10 y 14 años en los que los estudiantes analizaron uno de sus proyectos Scratch con Dr. Scratch, leyeron la información del informe de resultados e intentaron mejorar sus proyectos usando los consejos ofrecidos por la herramienta. Al finalizar el taller los alumnos mejoraron su puntuación de PC así como sus habilidades como programadores. One of the barriers to entry of computer programming in schools is the lack of tools that support educators in the assessment of student projects. In order to amend this situation this paper presents Dr. Scratch, a web application that allows teachers and students to automatically analyze projects coded in Scratch, the most used programming language in primary and secondary education worldwide, to check if they have been properly programmed, learn from their mistakes and get feedback to improve their code and develop their Computational Thinking (CT) skills. One of the goals of Dr. Scratch, besides supporting teachers in the evaluation tasks, is to act as a stimulus to encourage students to keep on improving their programming skills. Aiming to check its effectiveness regarding this objective, workshops with students in the range from 10 to 14 years were run in 8 schools, in which over 100 learners analyzed one of their Scratch projects with Dr. Scratch, read the information displayed as feedback by Dr. Scratch, and tried to improve their projects using the guidelines and tips offered by the tool. Our results show that at the end of the workshop, students increased their CT score and, consequently, improved their coding skills.

Computational thinking (CT) is being consolidated as a key set of problem-solving skills that must be developed by the students to excel in our software-driven society. However, in psychological terms, CT is still a poorly defined construct, given that its nomological network has not been established yet. In a previous paper, we started to address this issue studying the correlations between CT and some fundamental cognitive variables, such as primary mental abilities and problem-solving ability. The current work deepens in the same direction as it aims to extend the nomological network of CT with non-cognitive factors, through the study of the correlations between CT, self-efficacy and the several dimensions from the ‘Big Five’ model of human personality: Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. To do so, the Computational Thinking Test (CTt) and some additional self-efficacy items are administered on a sample of 1251 Spanish students from 5th to 10th grade ( N = 1251), and the Big Five Questionnaire-Children version (BFQ-C) is also taken by a subsample from the above ( n = 99). Results show statistically significant correlations between CT and self-efficacy perception relative to CT performance ( r s = 0.41), in which gender differences in favor of males are found ( d = 0.42). Moreover, results show statistically significant correlations between CT and: Openness to Experience ( r = 0.41), Extraversion ( r = 0.30), and Conscientiousness ( r = 0.27). These findings are consistent with the existing literature except for the unexpected correlation between CT and the Extraversion factor of personality, which is consequently discussed in detail. Overall, our findings corroborate the existence of a non-cognitive side of CT that should be taken into account by educational policies and interventions aimed at fostering CT. As a final contribution, the extended nomological network of CT integrating cognitive and non-cognitive variables is depicted. [ABSTRACT FROM AUTHOR]

Computational thinking (CT) is being located at the focus of educational innovation, as a set of problem-solving skills that must be acquired by the new generations of students to thrive in a digital world full of objects driven by software. However, there is still no consensus on a CT definition or how to measure it. In response, we attempt to address both issues from a psychometric approach. On the one hand, a Computational Thinking Test (CTt) is administered on a sample of 1,251 Spanish students from 5th to 10th grade, so its descriptive statistics and reliability are reported in this paper. On the second hand, the criterion validity of the CTt is studied with respect to other standardized psychological tests: the Primary Mental Abilities (PMA) battery, and the RP30 problem-solving test. Thus, it is intended to provide a new instrument for CT measurement and additionally give evidence of the nature of CT through its associations with key related psychological constructs. Results show statistically significant correlations at least moderately intense between CT and: spatial ability ( r = 0.44), reasoning ability ( r = 0.44), and problem-solving ability ( r = 0.67). These results are consistent with recent theoretical proposals linking CT to some components of the Cattel-Horn-Carroll (CHC) model of intelligence, and corroborate the conceptualization of CT as a problem-solving ability.

Several authors and studies highlight the benefits of the integration of Computer Science into K-12 education. Applications such as Scratch have been demonstrated to be effective in educational environments. The aim of this study is to assess the use of a Visual Programming Language using Scratch in classroom practice, analyzing the outcomes and attitudes of 107 primary school students from 5th to 6th grade in five different schools in Spain. The intervention takes place in two academic years analyzing the practice of integrating coding and visual blocks programming in sciences and arts. The “Computational concepts and computational practices” dimension details a quasi-experimental approach, which showed significant improvement regarding learning programming concepts, logic, and computational practices with an active approach. The “Learning processes and coding in primary education” dimension analyzes the practice of the experimental group through questionnaires and structured observation. In this pedagogical design, students interact and create their own content related to curricular areas with several advantages, such as motivation, fun, commitment, and enthusiasm, showing improvements related to computational thinking and computational practices. Understanding of computational concepts through an active approach, Project Based Learning, usefulness, motivation, and commitment underline the importance and effectiveness of implementing a Visual Programming Language from active methodologies in primary education. Due to the aforementioned benefits and positive results obtained in this research, it is recommended to implement a Visual Programming Language in educational settings in 5th and 6th grade in primary education through a cross-curricular implementation.
