... Las investigaciones relacionadas sobre el proceso de enseñanzaaprendizaje, continúan siendo por muchos años una preocupación de profesores e investigadores de todo el mundo, que aspiran a transformar el tradicional funcionamiento de la docencia en la que el alumno desempeña un rol de espectador y el profesor representa el actor principal, que en ocasiones no supera la simple transmisión de conocimientos (Rohman et al., 2019;Guo et al., 2020). En los últimos años, las instituciones de enseñanza superior han intentado dotar a los estudiantes de competencias cognitivas y profesionales (Vogler et al., 2018). ...
La investigación en la búsqueda de propuestas que transformen el proceso de enseñanza-aprendizaje de la Física en la educación preuniversitaria, tuvo como objetivo proponer una metodología que incorpore el método de proyectos en el proceso de enseñanza-aprendizaje, para contribuir al desarrollo de la motivación por el estudio de la asignatura Física en los alumnos y que estos se conviertan en protagonistas de su propio aprendizaje. Para el desarrollo de la investigación, se emplearon métodos de recopilación y procesamiento de la información, dentro de este último se destacan la observación y la encuesta. La muestra seleccionada estuvo integrada por 196 alumnos del 10mo grado del Instituto Preuniversitario Urbano “Capitán Roberto Rodríguez Fernández”, enclavado en la ciudad de Santa Clara, Villa Clara, Cuba. Los resultados obtenidos con la aplicación de los métodos constataron que es necesario producir una transformación en los métodos de enseñanza-aprendizaje de la Física en el preuniversitario para estimular la motivación por el aprendizaje. Tales resultados sirvieron de base para diseñar y proponer dicha metodología, la cual fue sometida a criterios de expertos que la valoraron de pertinente. Finalmente se manifiesta la pertinencia de la Metodología para la Aplicación del Método de Proyectos.
... To overcome this issue, new methods such as computer application-based data logging need to be ap-plied. The use of computer applications as ICT products allows students to explore and understand the concepts of physics that are in a close relationship with everyday life easier [8]. One of the applications that can be utilized for data logging in physics experiments is Audacity. ...
... In this study, to measure the kinetic friction coefficient, the first thing to do was to determine the acceleration of motion m1 and m2 using equation (4). Next, the kinetic friction coefficient was calculated using equation (8). Variables that contributed to equation 4 and 8 were taken repetitively for 20 data retrieval times. ...

Referring to the results of study by Blau [20], Çoban and Erol [2], Gratton and Defrancesco [21], and Sari [7], the values obtained in this study can be considered as excellent results for the kinetic friction coefficient values for the materials of acrylic with acrylic and wood with acrylic. ...
This study is designed to produce an experimental device for the measurement of the kinetic friction coefficient of material through magnetic induction using Audacity application. The objects of material the kinetic friction coefficient of which is going to be measured is rough acrylic with rough acrylic and wood with rough acrylic. The experimental setup was performed on the motion system of the mass of objects m <sub>1</sub> and m <sub>2</sub> that were connected through a pulley on a table and three solenoids are put under a table as the Electromagnetic Field (EMF) sensor. Analysis of the calculation of kinetic friction coefficient used two concepts, i.e. the kinematics concept to identify the load acceleration and the concept of the dynamic to find the kinetic friction coefficient. The results of the measurement of kinetic friction coefficient in this study have a match with the results obtained in the other studies. Hence, the tools and experimental approaches generated in this study are excellent for use in the learning activities so that teachers can teach physics applicatively.
Many applications can support the physics laboratory today during the Covid-19 pandemic. Video tracker and Visual Basic for Application is the simplest application nowadays. In this work, we present the implementation of Video Tracker and Visual Basic for Application at home to measure elasticity modulus of Sheet-Shaped Material in physics Laboratory. There were two stages performed to obtain the elasticity modulus of sheet-shaped material. Firstly, the sample was placed in a curved position (curvature angle variation) then the image was recorded. The result of these photo recordings was processed using video tracker software. The data obtained were coordinates point mass of each sheet-shaped material curvature. These coordinate point masses are used to calculate elasticity modulus using the cantilever beam elasticity equation. Finally, we also measured directly on the material using tensile test equipment to confirm these results. The computed results showed that the elasticity modulus value was closed to the value obtained by direct measurement using a tensile strength device. Hence, this method has the potential to develop new ways of practice in the physics laboratory.
