In programming problem solving activities, sometimes, students need feedback to progress in the course, being positively affected by the received feedback. This paper presents an overview of the state of the art and practice of the feedback approaches on introductory programming. To this end, we have carried out a systematic literature mapping to understand and discuss the main approaches for providing and evaluating feedback used in the learning of novice programmers in the problem solving activity. Thus, according to a formal protocol, an automatic search was performed for papers from 2016 to 2021. As a result, 39 studies were selected for the final analysis. As a result, we propose three different categorizations: the main approaches to providing feedback, the main methods used in the evaluation and the main aspects and effects of the evaluated feedback.

Currently, recommendation system technology has been assumed as a promising approach to contribute to fashion domain in terms of electronic commerce. In this paper, we propose an approach for a clothing personalized recommendation system that is able to help the women to identify appropriate clothing categories together with models linked to clothing images, mainly based on their fashion styles and body types. To achieve this, besides an intelligent user interface, our recommendation approach deals with two main components: the user modeling and the clothing recommendation, which is responsible for recommending fashion clothing items to women. The user modeling is responsible for creating and updating the user model, including two main knowledge-based mechanisms: the first is responsible for automatically identifying the fashion style, and the second is responsible for detecting body type. We evaluated our recommendation approach and preliminary results indicate that it significantly supports the women with choices.

Abstract. This article addresses a problem found in Discussion Forums of Collaborative Systems with respect to little investment in the mechanisms IntroduçãoEste trabalho está inserido na temática de Sistemas Colaborativos, focado em processos de interação envolvendo aprendizes através da ferramenta assíncrona Fórum de Discussão Educacional. Assume-se aqui que a noção de interação é a base para viabilizar processos de colaboração e sua ausência, portanto, pode comprometer a qualidade da discussão do fórum. O fórum, embora sendo uma das ferramentas mais utilizadas nos ambientes virtuais de aprendizagem que se presta a viabilizar a interação entre os atores envolvidos (professores, tutores e aprendizes), ainda apresenta algumas limitações importantes, a exemplo dos baixos níveis de interação entre aprendizes, tais como discutidos nos estudos mencionados a seguir.O estudo de Andriola e Loureiro (2005, p. 03) constatou um fórum que "das 144 mensagens trocadas, aproximadamente 91% deram-se entre um integrante do grupo e o II Congresso Brasileiro de Informática na Educação (CBIE 2013) XXIV Simpósio Brasileiro de Informática na Educação (SBIE 2013) 416
