Teaching and learning programming constitutes a challenge. Although several teaching approaches and programming tools have been proposed, it seems that they have limited impact on classroom practice. This article investigates students' perceptions on five educational programming environments that are widely used and the features that any introductory programming environment should have. The environments investigated are: BlueJ; objectKarel; Scratch; Alice; and MIT App inventor. These environments were studied and used by experienced undergraduate students of Informatics in the context of a fourth year course. The main features of the environments and the way of presenting them to students, as well as the assignments in the context of the course are presented, in order to help the reader realize what experience was gained by the students that evaluated the environments. Based on a questionnaire filled in by students interesting conclusions were drawn. Students identified the main features of the environments and evaluated them positively, although problems were identified. An introductory programming environment should engage students through the development of programs connected to their interests, such as games and mobile apps. Moreover, an ideal introductory programming environment should provide a simple and user-friendly Graphical User Interface (GUI) that supports visualization of objects and classes, includes a puzzle-like editor for program development, reports simple and understandable error messages in natural language, and finally the ability to Educ Inf Technol execute the program in a step by step manner. Although no single environment fulfils all these features, it seems that the most successful environment is Scratch.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
