Testing student interpretation of kinematics graphs
American Journal of Physics, 1994Recent work has uncovered a consistent set of student difficulties with graphs of position, velocity, and acceleration versus time. These include misinterpreting graphs as pictures, slope/height confusion, problems finding the slopes of lines not passing through the origin, and the inability to interpret the meaning of the area under various graph ...

African Journal of Research in Mathematics, Science and Technology Education, 2017
Students’ graph comprehension may be affected by the background of the students who are the readers or interpreters of the graph, their knowledge of the context in which the graph is set, and the inferential processes required by the graph operation. This research study investigated these aspects of graph comprehension for 152 first year undergraduate ...

Modifying the test of understanding graphs in kinematics
2018In this article, we present several modifications to the Test of Understanding Graphs in Kinematics. The most significant changes are (i) the addition and removal of items to achieve parallelism in the objectives (dimensions) of the test, thus allowing comparisons of students’ performance that were not possible with the original version, and (ii ...

Kinematic structure of mechanisms: a bond graph approach
Journal of the Franklin Institute, 1991Abstract It is proposed to use the bond graph framework for performing the type synthesis of mechanisms. Starting from the standard bond graph modelling approaches of rigid multibody systems, two word bond graph representations of kinematic structures are defined.

Modeling and simulation of biped kinematics using bond-graphs
2006 International Conference on Emerging Technologies, 2006Robots are considered as ideal multidomain or mechatronic systems. A biped or two-legged walking robot incorporates robust mechanical design, efficient electronics and intelligent motion control techniques to balance itself while standing and walking. Location of center of gravity (COG) of the robot is the key to its stability.

Kinematics-based Force-Directed Graph Embedding
This dissertation introduces a novel graph embedding paradigm, leveraging a force-directed scheme for graph embedding. In the field of graph embedding, an "embedding" refers to the process of transforming elements of a graph such as nodes, or edges, or potentially other structural information of the graph into a low-dimensional space, typically a ...openaire +1 more source
