6. Audience Response Software as a Learning Tool in University Courses

Author

Díez-Pascual, Ana María and Díaz, María Pilar García

Abstract

The use of information and communication technologies (ICTs) has become a fundamental tool in all areas of today's society, including higher education. Lessons cannot be envisaged without the use of tools such as computers, tablets or mobile devices. Many lecturers use audience response systems (ARS) to keep their classes engaged. ARS software allows teachers to interact with students via polls, text responses, or multiple-choice questions displayed via their mobile devices. A new example of the use of this type of devices in education is gamification, a technique that uses a set of activities with ludic character as a learning methodology in order to facilitate the acquisition of knowledge and competences. One of the most used gamification tools is Kahoot!, a free learning application based on a mixture of game and creativity, which encourages attention and participation of students through questions and answers formulated by the teacher and designed in a way that students respond via their mobile phones. This paper examines the use of Kahoot! in a subject belonging to the chemistry area. In order to assess the benefits of this tool, it was tested in a group of students to review the knowledge and skills acquired during the theoretical lessons prior to the exams, and the academic results were compared with those of a control group of students who did not use the tool. The results demonstrate that the use of Kahoot! led to an improvement in the teaching--learning process of the students and a noteworthy rise in their marks, and that its positive effects rise with increasing the frequency of use of this didactic tool.

Abstract

The early diagnosis of certain fatal diseases is vital for preventing severe consequences and contributes to a more effective treatment. Despite numerous conventional methods to realize this goal, employing nanobiosensors is a novel approach that provides a fast and precise detection. Recently, nanomaterials have been widely applied as biosensors with distinctive features. Graphite phase carbon nitride (g-C3N4) is a two-dimensional (2D) carbon-based nanostructure that has received attention in biosensing. Biocompatibility, biodegradability, semiconductivity, high photoluminescence yield, low-cost synthesis, easy production process, antimicrobial activity, and high stability are prominent properties that have rendered g-C3N4 a promising candidate to be used in electrochemical, optical, and other kinds of biosensors. This review presents the g-C3N4 unique features, synthesis methods, and g-C3N4-based nanomaterials. In addition, recent relevant studies on using g-C3N4 in biosensors in regard to improving treatment pathways are reviewed.

16. Experience in the Use of Social Software to Support Student Learning in University Courses of Science and Engineering Degrees

Abstract

A "wiki" is an easy-to-use online tool for teachers and students, as it is a collaborative website that provides the opportunity to develop and modify its content to every member in an interactive and fast way. This paper comparatively describes experiences in the implementation of "wikis" as voluntary activities in first-year courses in a degree in Chemistry and third-year courses in a degree in Telecommunication System Engineering. The main goal of using the wikis was to achieve collaboration among students to generate knowledge. The developed methodology was applied to the resolution of exercises, problems, and test questions, as well as to the elaboration of class notes and a bilingual glossary. The approach turned the students into active learners, increasing their interest in the course contents, promoting knowledge exchange among students and encouraging the self-management of their learning process. The role of the teacher was to provide feedback to the students in order to ensure the accuracy of the contents. Four different patterns were distinguished among the students according to their participation level in the wiki. The students who were most committed to the courses were also the most involved in the "wikis", and the combination resulted in the students' success. The results obtained for the degree in Chemistry were better than those of the degree in Telecommunication System Engineering, which was ascribed to the increased connection among the first-year students. The didactic strategy was very positive, although the percentage of participation in the "wikis" was somewhat low, in particular for the third-year students, who were more independent and self-organized. Initially, the number of wiki visits increased suddenly, and then moved to a long period of lower activity in the degree of Chemistry and lethargy in the degree of Telecommunication System Engineering. Therefore, it is desirable to introduce modifications in the approach, such as flexible and consensual planning with the students in order to ensure their full engagement.
