Visualization is a technology frequently used to assist the learning of algorithms. In this paper, two program visualization proposals are presented, for search algorithms in state-spaces, such as backtracking and branch and bound algorithms. Firstly, it is studied the coding schemes more adequate to generate recursion trees which may represent search trees. Secondly, two novel visualizations are presented, called line views. They display the time evolution of the values handled during the search process for optimization problems, especially in branch and bound algorithms.

This study aims to socialize students’ perception of their experiences appropriating digital network technologies in a reflective process developed in the Technology, Education, and Learning distance discipline of the Pedagogy course at Universidade do Estado de Santa Catarina. The discipline was planned for the first time in the second semester of 2019 and coimplemented by two professors in the area. The discipline was reoffered in the first half of 2021 after being rethought according to the pandemic. The data in this report were collected from ebooks and self-evaluating processes performed in four classes, three from the first offer of the discipline and one from the second one. Results showed that students had difficulties appropriating Canva but managed to produce e-books which related the studied contents and their experiences. Moreover, our planning of the discipline positively surprised students by offering reflections on how cyberculture cross their lives.

Currently, digital technologies are an effective and prevalent means for communication, interaction and information sharing in different sectors of society. In education, technological tools are used for a multiplicity of objectives and contexts, for research, teaching and learning. An educational platform can promote debate between different actors and bring together knowledge, multidisciplinary experiences and educational resources, following open science principles. In this article, we describe the development process of the OESC Platform, which aims to be an educational platform for researchers, teachers, students, media, politicians and the public in general. We present its main areas and features, which include a content repository, social area and e-learning tools.

Educational software has often been used to promote self-regulated learning (SRL), a psychological construct associated with improved academic performance. In introductory programming education, high-performing students often present a solid use of SRL strategies, which aroused the interest of educators and researchers in studying this phenomenon. A typical procedure in research grounded on the SRL theory is the measurement of students’ regulatory abilities. For example, to assess modifications in SRL behavior after exposure to computer-based scaffoldings. Due to the lack of instruments that measure specific regulatory strategies related to programming learning, the Self-Regulation Programming Strategies Questionnaire (SPSQ) was developed by Lu et al. The use of this instrument depends upon its reliability and validity, aspects measured by psychometrics replications, which is missing and is our objective in this work. Ninety-five undergraduate computer science students from Macao participated in this investigation. The findings point to the SPSQ’s reliability and validity, and our study goes further by providing a confirmatory factor analysis of this instrument, which was absent in the original study.
