Publicação Acesso Aberto CS1 Student Grade Prediction: Unconscious Optimism vs Insecurity?2021 - Sobral, Sónia RollandThe difficulties of many students in introductory programming courses and the consequent failure and drop out make it necessary to look for motivation strategies for them to be successful. One of the strategies that is touted in the literature is self-assessment to compromise and motivate students. As we had doubts about the possibility of this strategy, we did an experiment and asked the students to predict the grades of the two tests and the two projects during a semester. Even knowing the correction grid and exercises that involve programming languages, which shows the result to the programmer, we found that the students' forecasts were not very accurate. In the first test we found that the worst students said they were going to get reasonable grades and much better than reality, while the best students thought they had worse grades than they actually had. The other moments of evaluation did not have as severe results, but forecasts continued to be inaccurate. We did tests by gender, by age, for being a freshman or not, for having taken a computer course in high school and for previous knowledge of programming languages: none of these variables proved to be as significant as the students' grades and their corresponding insecurity-fear or optimism-unconscious.Publicação Acesso Restrito CS1 student grade prediction: unconscious optimism vs insecurity?2020-07 - Sobral, Sónia RollandThe difficulties of many students in introductory programming courses and the consequent failure and drop out make it necessary to look for motivation strategies for them to be successful.

There has been very important work with curriculum recommendations, notably those from Association for Computing Machinery (ACM) and later ACM in conjunction with the Institute of Electrical and Electronics Engineers (IEEE): so far almost twenty curriculum recommendations have been published. Computing is a constantly evolving area, as is society and the way new generations learn. Why are so many recommendations needed? And what are the developments in these recommendations? This article lists initial course units that are suggested or used as examples in each of the curriculum recommendation reports, both initial and generic, and those that address a specific area, namely Computer Engineering (CE), Computer Science (CS), Information Systems (IS), Information Technology (IT), and Software Engineering (SE). This study is of great importance for those who have the responsibility to design and redesign curricula as it points out a number of different paths, namely in relation to the already mentioned distinction by areas but also the distinction that is made by university size, previous knowledge of the students, and also duration of studies, among other variables. Knowing history makes it possible to understand the present and even make better choices for the future.Publicação Acesso Restrito Bloom's Taxonomy to improve teaching-learning in introduction to programming2020 - Sobral, Sónia RollandStudents in computer science courses entering higher education begin with computer thinking and programming languages in a curricular unit (CU) that can be referred to in various ways, like CS1 or programming fundamentals. This CU is very important for the academic and professional path of those students. Teachers and those responsible for those courses must carefully define the learning objectives, the learning strategies and the assessment of this teaching-learning. Bloom's taxonomy, in its different variations, is a powerful tool that helps in these tasks and that gives clear indications on the language that is to be used - which is useful for perceiving both the level of colleagues and the level of accreditations and assessments of courses. This article provides a detailed description of Bloom's taxonomy and its changes over the years. Studies carried out in the context of teaching fundamentals of programming and using Bloom's taxonomy are listed and analyzed. In the end, the conclusions and the definition of future works are made.Publicação Acesso Aberto Pair Programming and the Level of Knowledge in the Formation of Pairs2021 - Sobral, Sónia RollandThe pandemic situation COVID-19 requires teachers to rethink some of the activities proposed to students since even though they are physically in the same room at the university, they cannot join and must maintain a social distance. The curricular unit of introduction to programming in the first year of computer courses requires several activities: students only learn by doing. One of the activities that has been used a lot in the academic community is pair programming: a single computer for two students working together. In the case that this article reports the pair works sharing a ZOOM room and alternates the position of driver (writes the code) with navigator (one that comments on the code). This article uses the technique of pair programming for writing top-down, algorithm and traces to verify the behavior of variables along the algorithm. If the pair programming technique has had very interesting results in terms of task speed and code quality far superior to programmers alone, there are some doubts about the problem of the constitution pf the groups. In this article we use two opposite strategies: group students with opposite knowledge or group students with similar knowledge. We found that students who prefer this activity are the worst ones (in both strategies) and the best students when grouped with colleagues with similar knowledge.Publicação Acesso Aberto CS1: C, Java or Python? Tips for a conscious choice2019 - Sobral, Sónia RollandIntroduction to programming languages is a fundamental point for the beginning of students in the world of computing. The success of programming fundamentals is essential to student success during their academic career. The subject taught in technology courses is a major concern for teachers and course direction. Throughout history it has been verified that the great alterations presented were the new programming languages and paradigms, at least the transition from structured programming to object oriented programming. The content of curricular units remains the same. 30 years ago it was common to use a programming language based on BASIC. Twenty years ago Turbo Pascal was used. In the last 10 years there is a discussion about the use of C, java and Python for first contact with programming. In previous studies we verified that these are the three programming languages most used in the first semester of the courses in computer science. In the second semesters the most used languages are C, C ++ and java. There are two paths to follow: using the same programming language in the first two semesters or using one language in the first semester and another in the second. This last path usually happens with Python and C. The choice which programming language taught is often like that of a football club or religious option, other times it is linked to other important factors such as applications from employers in the world outside the university. This article reflects on the choice of which programming language to adopt in CS1, lists the languages currently most widely adopted in the real world, and used in introductory programming courses in higher education, as well as some studies to choose the initial language. Pedagogical questions and the preparation of students for work are the most important questions. This article list some items that can and should be considered for a conscious choice.Publicação Acesso Aberto Predicting students performance in introductory programming courses: a literature review2021 - Oliveira, Catarina Félix de; Sobral, Sónia RollandThe teaching-learning process in programming in university with freshmen is often associated with high failure and dropout rates. These outcomes frustrate both students and teachers and there is a need to verify the causes of these failures. By predicting the causes of these problems, we can try to control them, or at least try to plan the courses to try to avoid failure in the identified cases. The purpose of this paper is to analyze the scientific production concerning the prediction of students’ performance in introductory programming courses. This analysis regards articles indexed in Clarivate Analytics’ Web of Science and Elsevier’s Scopus. The sample includes a total of 30 articles. The results obtained by bibliometric analysis show when and where those documents were published, who are the authors and what is the focus of said articles. We also analyzed the most cited documents. We made a summary of the articles. We were able to obtain a global overview of the theme, obtaining a strong analysis that is useful for teachers in the process of helping students achieve success in introductory programming courses at universities.Publicação Acesso Restrito Is pair programing in Higher Education a good strategy?2020 - Sobral, Sónia RollandPair programming is by definition two-person programming on the same computer. The technique has been used in many higher education institutions and has been reported in some scientific articles, usually for introductory to programming courses. The aim of this article is to make a situation report analyzing the scientific production on pair programming for curricular units of introduction to programming in higher education, measuring the advantages and disadvantages of the strategy. The sample was composed by 153 articles indexed in Elsevier’s Scopus. The results obtained by bibliometric analysis showed the publication rates, authors, in which journals they are published, which are the organizations and countries that publish the most, which are the most cited articles and what their purpose. The benefits reported are generally better code, improved programming and group skills, advantages for women and reducing the work of instructors. The problems are group compatibility: there are studies that randomly distribute pairs, while other use personality tests or knowledge self-assessment.Publicação Acesso Aberto Is pair programing in Higher Education a good strategy?2020-12 - Sobral, Sónia RollandPair programming is by definition two-person programming on the same computer.

Disapproval and dropout rates are a concern for everyone concerned with the topic. Therefore, it is necessary to look for strategies that improve the motivation of students who start a programming course, also improving success rates and decreasing dropout rates. The inverted class model, or flipped classroom, has been used in several experiments, showing very good results. The objectives of this teaching-learning technique is to change the traditional order: students have contact with new subjects before the classroom, using videos, texts or other material, as well as small online tests to check their knowledge. In this way, the face-to-face classes are reserved for discussion, doubts and application of previously acquired knowledge. The purpose of this paper is to analyse the scientific production on Flipped classrooms in introductory programming courses indexed in Elsevier’s Scopus. The sample is composed by 45 articles in total. The results obtained by bibliometric analysis showed when and where those documents are published, who the authors are and what the focus of said articles is. We also analysed the most cited documents. We made a summary of the articles, namely in what refers to the sample size of the experiences, which programming language is used, in which universities the articles are made, which technology is used, as well as which methods are used in order to create inverted classes and which are the objectives and results of these experiences reported on the articles.. We managed to get a global view of the theme, getting a strong analysis for those who want to use flipped classrooms for teaching programming.
