2 Attitude of University Students in the Use of Artificial Intelligence

Authors: R. Merlo, M. González, Z. Rivero, L. González

Abstract:

This exploratory work aimed to understand university students’ perceptions of the use of artificial intelligence (AI) during their time in the classroom. The significance of using AI in education, the degree of interest, knowledge acquisition, and how it would influence an interactive resource for acquiring skills were explored. Within this framework, a test with 30 items was designed and administered to 800 volunteer first-year university students of natural and exact sciences. Based on a randomized pilot test, it was validated with Cronbach's alpha coefficient. Descriptive statistics of the sample used allowed us to observe the preponderance of the dimensions that constitute the attitude construct. Subsequently, factor analysis by dimensions provided insights into the students' habits, according to the knowledge acquired and the emotions engaged during the topics developed in the classroom.

Keywords: Attitude, artificial intelligence, didactics, teaching.

1 Determination of the Gain in Learning the Free-Fall Motion of Bodies by Applying the Resource of Previous Concepts

Authors: Ricardo Merlo

Abstract:

In this paper, we analyzed the different didactic proposals for teaching about the free fall motion of bodies available online. An important aspect was the interpretation of the direction and sense of the acceleration of gravity and of the falling velocity of a body, which is why we found different applications of the Cartesian reference system used and also different graphical presentations of the velocity as a function of time and of the distance traveled vertically by the body in the period of time that it was dropped from a height h0. In this framework, a survey of previous concepts was applied to a voluntary group of first-year university students of an Engineering degree before and after the development of the class of the subject in question. Then, Hake's index (0.52) was determined, which resulted in an average learning gain from the meaningful use of the reference system and the respective graphs of velocity versus time and height versus time.

Keywords: Didactic gain, free–fall, physics teaching, previous knowledge.
