HUM-432: How people learn: Designing Learning Tools I

The students will understand the cognitive and social factors which affect learning - particularly in science and engineering. They will be able to use social research techniques as part of the design process to understand end users. ...

Description

This lecture introduces a motor control experiment that requires two participants to work together. One person acts as the experimenter, while the other is the research subject. The research subject must tap specific fingers based on colors displayed on the screen, aiming for accuracy and speed. The experimenter tracks errors made by the subject. Through multiple trials, the lecture explores how errors change over time, highlighting the impact of practicing a skill and the challenges of multitasking. The instructor prompts viewers to reflect on why errors increased when participants had to manage two tasks simultaneously.

Roland John Tormey

I am a sociologist and learning scientist researching and teaching on engineering education. I'm particularly focused on the roles of emotion and self-regulation in engineering teaching and learning. My profile is accessible here.

Nihat Kotluk

Dr. Kotluk is currently a post-doc at the EPFL. He focuses mainly on emotions in the decision-making process, moral reasoning, and ethics in Engineering Education. He also works on equality and diversity issues. He has an academic background in both STEM and social sciences. Dr. Kotluk has acquired advanced skills in education, inclusive pedagogy, and science teachers' training. He has 14 years of teaching experience and has trained high school students in physics and teachers in pedagogy and research methods, among others. Dr. Kotluk has strong teaching and learning communication skills. He holds a Ph.D. in Educational Science, Curriculum, and Instruction. In his thesis, he studied the perceptions and practices of educators in culturally relevant pedagogy and developed recommendations to put more emphasis on inclusion in pre-service teacher education. With his research, he opened a new discussion in the academic community in Turkey and internationally. In his recent work, he analyzes the educational challenges facing refugee communities and other marginalized groups. In the study, he focused on whether and how teachers implemented the principles of culturally relevant and sustaining pedagogies and the challenges teachers faced while trying to implement these principles with Syrian students in Turkey. In his more recent work, he has studied moral emotions, moral reasoning in engineering ethics, and equality and diversity issues in engineering education. His teaching and research interests include emotions in engineering education, culturally responsive STEM education, equity and diversity in education, and multicultural education.

Motor controller

A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical faults. Motor controllers may use electromechanical switching, or may use power electronics devices to regulate the speed and direction of a motor.

Vector control (motor)

Vector control, also called field-oriented control (FOC), is a variable-frequency drive (VFD) control method in which the stator currents of a three-phase AC or brushless DC electric motor are identified as two orthogonal components that can be visualized with a vector. One component defines the magnetic flux of the motor, the other the torque. The control system of the drive calculates the corresponding current component references from the flux and torque references given by the drive's speed control.

Ward Leonard control

Ward Leonard control, also known as the Ward Leonard drive system, was a widely used DC motor speed control system introduced by Harry Ward Leonard in 1891. In the early 1900s, the control system of Ward Leonard was adopted by the U.S. Navy and also used in passenger lifts of large mines. It also provided a solution to a moving sidewalk at the Paris Exposition of 1900, where many others had failed to operate properly. It was applied to railway locomotives used in World War I, and was used in anti-aircraft radars in World War II.

Motor control

Motor control is the regulation of movement in organisms that possess a nervous system. Motor control includes reflexes as well as directed movement. To control movement, the nervous system must integrate multimodal sensory information (both from the external world as well as proprioception) and elicit the necessary signals to recruit muscles to carry out a goal. This pathway spans many disciplines, including multisensory integration, signal processing, coordination, biomechanics, and cognition, and the computational challenges are often discussed under the term sensorimotor control.

Electric motor

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.
