Abstract:
It is of fundamental importance the mastery of Physics contents for the understanding of Acoustic Comfort. In this sense, it is up to the teacher to become aware of students’ prior knowledge, to give a new meaning to the cognitive structures that make it possible to transform their difficulties into learning potential. In this work, educational teaching/learning interventions were developed and focused on the Theory of Meaningful Learning. These case studies were carried out with several students in different classes in the same program. In addition to the pre- and post-intervention questionnaire, Computational Educational Tools were used in order to assess the previous concepts and the effectiveness and efficiency of the provided pedagogical intervention. Satisfactory results were obtained with a reduction of about 250% in terms of alternative conceptions to the scientific knowledge previously detected in the participating volunteer students. The analysis was based on the approach of Ausubel and collaborators’ Meaningful Learning theories, contextualized to the content of Acoustic Physics and applied in the classes of the Environmental Comfort course in the Civil Engineering and Civil Construction Technology programs from 2012 to 2018.

Abstract:
The objective of this quantitative research with correlational scope was to determine the relationship between the use of information and communication technologies and self-efficacy in older adults, in order to demonstrate the benefits offered by these technologies in this age group. In this study, 380 retired older adults, most of whom were married and have some technological device in their homes, participated. Two instruments were applied in different social and recreational senior housing facilities: a scale of ICT use and another to measure self-efficacy. The results showed that the most used technological resources are smartphones and the Internet. The use of technologies for communication and learning is associated with self-efficacy, which proves that digital literacy will improve the performance of older adults, in addition to improving their quality of life.

Authors:
J. Á. Ariza and S. G. Gil
Abstract:
This article describes the development and assessment of RaspyLab which is a low-cost Remote Laboratory (RL) to learn and teach programming with Raspberry Pi and Python language. The RL is composed of 16 stations or nodes that contain hardware components such as display LCD, robotic arm, temperature sensor, among others, and two modes of programming (graphical and text-based) for the students to experiment with their designed algorithms. The concept of the RL was conceived as a pedagogical tool to support the students of Engineering and Computer Science (CS) in an online learning format, given the context of the COVID-19 pandemic. The laboratory has been used by ( ${n} =30$ ) CS students during the second semester of 2020 in the subject of mathematical logic through the methodology of Problem-Based Learning (PBL). To evaluate preliminary the laboratory, it was used a survey with 3 open-ended questions and 12 closed-ended questions on a Likert scale according to the Technology Acceptance Model (TAM). The outcomes show a good reception of the laboratory, an enhancement of the students’ learning regarding the concepts addressed in the course, and an interest of the students for the laboratory to be included in other subjects of the curricula.

S. Trilles, A. Monfort-Muriach, Á. Gómez-Cambronero and C. Granell
Abstract:
This paper describes a new technological evolution of the Sucre project, which aims to foster a vocation for science and develop computational thinking and programming skills in pre-university students. This improved version is called Sucre4Stem and has been designed from the Internet of Things perspective. At a technological level, we differentiate two main tools, SucreCore andSucreCode. SucreCore provides a new, more compact design, encapsulates an advanced microcontroller and supports wireless connectivity with the ability to create online variables and functions. SucreCode, the block-based visual programming tool, has a revamped interface and allows wireless communication with SucreCore. At the pedagogical level, Sucre4Stem makes it easier to implement new group dynamics and to create novel types of collaborative projects between groups of students. In this article, we also explore how these collaborative projects can be carried out by taking advantage of the different types of communications between SucreCore and the server-side platform using shared online variables and functions.

(Cerrando la brecha entre la teoría y el aprendizaje activo: un estudio de caso de aprendizaje basado en proyectos en el curso introducción a ciencia e ingeniería de materiales)
Authors:
H. A. C. Lopera, E. Gutiérrez-Velásquez and N. Ballesteros
Abstract:
The current investigation is a case study of project-based learning methodology (PBL) applied to one of the most widespread engineering basic courses: introduction to materials science and engineering. The project was conducted with first year undergraduate students of Mechanical Engineering. For this, some of the theory-based class lecture was reduced to fit 40% of a multidisciplinary project that required producing walking sticks and crutches for people with limited mobility while using inexpensive materials and the most preferred solid waste materials. Students participating in this project designed, tested, and evaluated each other’s final product. In addition, students presented a technical report with an extended literature review that included information of the manufactured part. Differing from other PBL studies, the instructor evaluated the students’ progress at four different time points throughout the semester, through a summative evaluation process in which it was certified, through a qualification, in accordance with the learning developed during the mediation process with the students. Students, faculty members, professionals, and local experts in the manufactured parts were given a survey to evaluate the fabricated parts for aesthetics and innovation. A non-profit organization also participated in sensitizing the students to provide better solutions for people with several oral presentations during the class time. To assess the effectiveness of the PBL method, the Mechanical Engineering course was compared to another one using a traditional teaching approach, where the comparison was based on the same exams administered on both study groups. The method implemented in this study has proven to be a good strategy for teaching materials engineering courses, allowing students to participate in interdisciplinary projects. From this experience, it is concluded that it is feasible to implement active methods as an alternative to the courses taught using only traditional methods.

Abstract:
Robotics not only play a significant role in medicine, manufacturing, or aerospace industry, but also in education. According to governmental studies carried out in the United States and Europe, careers related to STEM skills like engineering, are constantly increasing worldwide. Due to this, several countries have been implementing STEM education. But, in Colombia this initiative just recently started to take place. Currently, it is possible to find several STEM educational robotic kits on the market such as boost from Lego, Cozmo from Anki, Mbot from Makeblocks and Dash from Make wonder. In this trend, the STEM robotic kit proposed in this document, pretends to be a hardware grounding to implement a whole STEAM program. It intends to encourage children to develop their science, tech, math, and artistic outcomes. Also, the kit offers a differential plus from others because it has two interactive components: an elephant-bot called Eli, a robot easy to assemble inspired in the protection of African elephants; and, an intuitive user interface, called “Experiencia Chamali” made up of three modules. The first one consists of assembly the robot, the second one is designed for developing of spatial perception throughout maze challenges, and the last one is made for test the robot’s movements live. Two groups of children between 6 and 11 years old tested the robotic platform. During the activity, the groups reinforced STEM skills such as teamwork, communication, and problem-solving as a conclusion of test results. The children divided the assembly of the elephant-bot into several tasks on their initiative to make an agile construction. Also, in the challenge of the labyrinth, they worked collaboratively on the spatial location. Finally, the members of each group worked as a team decorating the physical labyrinth freely and observing the movements of the “elephant-bot” in this environment.

Abstract:
Open-source software (OSS) has become a valuable resource for corporate, educational, and social processes, reducing digital divides in emerging countries. This paper proposes an open-source software acceptance model (OSS-AM) to examine determinants of OSS adoption among students in emerging economies. A quantitative methodology with a descriptive correlational approach was employed, collecting data from a representative sample of 504 students. Confirmatory factor analysis showed strong associations between attitude towards use and variables such as compatibility, quality, flexibility, and security. This study reveals that skill development through practical education, perceived usefulness, training, and compatibility are the most influential factors in students’ adoption of OSS.
