In this learning activity, we’ll explore what RESTful services are, how they interact with clients and servers, and finally, understand how it works within an HTTP framework.
Learners answer 20 questions related to providing responsible customer service. The questions are presented in a game show format, and immediate feedback is provided. A final score is given at the end of the activity.
This learning object is designed to assist students in understanding and interpreting collision evidence found in automotive lamps. In particular, the concepts of Hot Shock, Cold Shock, Hot Break, and Cold Break will be visually addressed.
Police Officer Hiring: An Overview of the Selection Process
Learners read about the steps involved in the typical police officer hiring process. Each step is described. Learners then test their knowledge of the process in two drag-and-drop exercises.
Stain Measurement & Calculating Angles of Impact (Screencast)
In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).
A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.
Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.
