MUAHAH: Taking the Most out of Simple Conversational Agents

Authors: Leonor Llansol, João Santos, Luís Duarte, José Santos, Mariana Gaspar, Ana Alves, Hugo Gonçalo Oliveira, and Luísa Coheur

Published in: OASIcs, Volume 94, 10th Symposium on Languages, Applications and Technologies (SLATE 2021)

Abstract
Dialog engines based on multi-agent architectures usually select a single agent, deemed to be the most suitable for a given scenario or for responding to a specific request, and disregard the answers from all of the other available agents. In this work, we present a multi-agent plug-and-play architecture that: (i) enables the integration of different agents; (ii) includes a decision maker module, responsible for selecting a suitable answer out of the responses of different agents. As usual, a single agent can be chosen to provide the final answer, but the latter can also be obtained from the responses of several agents, according to a voting scheme. We also describe three case studies in which we test several agents and decision making strategies; and show how new agents and a new decision strategy can be easily plugged in and take advantage of this platform in different ways. Experimentation also confirms that considering several agents contributes to better responses.

Active Methodologies in Incoming Programming Classes (Short Paper)

Authors: João Paulo Aires, Simone Bello Kaminski Aires, Maria João Varanda Pereira, and Luís M. Alves

Published in: OASIcs, Volume 91, Second International Computer Programming Education Conference (ICPEC 2021)

Abstract
Innovative approaches in teaching programming have been required to improve the success of incoming programming students. This work presents the initial results of a teaching strategy implemented in the Algorithms subject of a Computer Science course. Ninety-five students, enrolled in this subject during the first semester of the course, participated in the research. The reported activity is related with active methodologies of teaching and Problem-Based Learning, being developed on the first day of class in groups of up to five students. The activity was based in two actions: 1) answering a questionnaire associating computing elements to daily life routines; and, 2) even without programming concepts knowledge, develop a smartphone application. Each group received a questionnaire containing 19 questions, divided into four blocks. What can be perceived with the accomplishment of this work, was the enthusiasm, motivation and engagement of the students who, even being unknown from each other, organized themselves in the groups and researched the necessary strategies to complete the challenge. The teacher acted as an advisor in the teaching process, conducting the experiment in order to lead students to find the solution.

EasyCoding - Methodology to Support Programming Learning

Authors: Marcela Viana P. Almeida, Luís M. Alves, Maria João Varanda Pereira, and Glívia Angélica R. Barbosa

Published in: OASIcs, Volume 81, First International Computer Programming Education Conference (ICPEC 2020)

Abstract
Knowing that the programming curricular units in the first year of engineering courses have a high failure rate and, assuming that this failure is due, in large part, to the lack of motivation and the lack of autonomy of the student to program in context outside the classroom, a methodology based on activity guides using attractive web platforms is proposed. The proposed methodology aims to facilitate both the planning of activities by the teachers and the autonomy and motivation by students. In order to receive a first feedback about this work, the methodology is being used by programming professors from Polytechnic Institute of Bragança, but in the near future it will be also evaluated by professors from the Federal Center of Technological Education of Minas Gerais and from the Federal Technological University of Paraná, both from Brazil. Following this work, a system is being developed that allows the automatic construction of guides based on exercises available from the web and systems that facilitate the collection of solutions and analysis of results.
