Living Physics Portal: Click-and-drag 2D Sequence of Motion Diagrams

Abstract: This is one of the modules in the Introductory Biomechanics series, which are sets of student activities on mechanics topics in the context of biomechanics for an introductory course. This module of activities introduces kinematics and Newton's laws in the context of human movement and humans moving objects. Modeling the human body as a point object and looking at human motion as sequences of simple motion segments are key components. This update includes PowerPoint worksheets with click-and-drag features, many based on student lab data. These worksheets include a focus on visualizations.

Resource Types: In-class activity, Lab, Restricted access

Remote Learning Ready: This resource has been designed or adapted for use in remote learning.

INSTRUCTOR GUIDE

IMPLEMENTATION

Equipment required: Computers / software; Specialized physics equipment; Other

Specific equipment needed: Many activities/worksheets prepare students to predict, interpret, and analyze data using data from previous students, and do not require any equipment. Students can incorporate their own data into similar click-and-drag templates to interpret and analyze their own data . The lab data acquisition may require the use of a camera or webcam for video analysis, and/or 1D or 2D force platforms, force sensors, motion sensors for computer acquisition and graphical display. We used Pasco's Capstone software and Pasco sensors, but Vernier's LoggerPro software and sensors could be used a well (except for 2D force plates)

Basic implementation tips & tricks: These materials were developed for use in a small workshop-style class where laboratory activities are integrated with other activities. The smaller activities are meant to be interwoven with other class activities. For use in a standard lab or recitation format, several activities could be combined. The click-and-drag worksheets, created to accommodate remote learning, are now used in in-person classes, with student digital submission. The motion diagram and graph prediction activities are done pre-lab. Graph interpretation and analysis activities can be used with or without students' own data for group or individual work.

How does this resource fit into the flow of your course? Following the modules on fundamental interactions and force equilibrium, this module goes into more detail about motion and Newton's Laws, in the context of locomotion and humans moving objects. Students next build on these ideas in exploring and analyzing human movement from an energy perspective and then a rotational dynamic perspective, where muscle force can be estimated during these same movements. The course is taught in a workshop style, where lab activities are integrated with other class activities. The module's activities are used as active lecture components, lab and class group activities, and individual homework.

PEDAGOGY

Pedagogical approach: Collaborative problem-solving; Conceptually-oriented activities; Context-rich problems; Project-based learning; Guided inquiry; SCALE-UP / studio / workshop physics; Modeling Instruction; Mathematically-focused activities; Experimentally-focused activities

Skills / Competencies: Functional dependence; Multiple representations; Estimation; Building models; Evaluating models; Performing experiments; Analyzing experimental data; Applying physical principles; Interdisciplinarity

What insights or realizations do you hope students gain from this resource? The locomotion of a whole human or animal body depends on how it pushes/pulls against its environment. This interaction with the environment can be related directly to the movement through Newton's Laws. The fundamental relationship between interactions and motion also applies to how human move objects and to the movement of all things at every scale, from the cells to the solar system.

Why is this resource useful to life sciences students? For pre-physical therapy, pre-occupational therapy or exercise students, biomechanics is particularly important. Pre-med and pre-vet also benefit from understanding human or animal locomotion and how humans manipulate objects. In this module students will lay the foundation to be able to analyze for themselves movement techniques for optimum sports performance, injury prevention, effective therapy or compare impaired and healthy movement,
