![]() ![]() The main difference between a virtual learning environment and a traditional learning environment is that traditional learning happens with face-to-face participation in classes offered in a physical space such as a school. How Does Virtual Learning Differ from Traditional Learning? Virtual learning works because it is more interactive when compared to courses simply offered online as eLearning. Virtual learning may include real-time video streaming (using virtual conference platforms) or asynchronous, on-demand classes with feedback and engagement from the instructor. The instructor communicates with the students using online video (live or on demand), forums, instant messaging, and email. The virtual learning experience is delivered via computer software, course content on the Internet, or some combination of both methods. ![]() I will share the tips that I know will help you even if you are completely new to virtual learning, so read on. You can quickly get up to speed with the newest techniques that make it easier for instructors to make compelling content for their online classes.Īfter decades of creating virtual learning experiences and reviewing hundreds of online classes, I learned many things that help make a better virtual learning environment. The language specification is the definitive source for C# syntax and usage.After reading this article, you will know everything there is to know about virtual learning, including how to make high-quality virtual learning environments and experiences that keep students engaged with compelling content if you’re a teacher or instructional designer. public Cylinder(double r, double h): base(r, h) ", l.Area()) įor more information, see the C# Language Specification. Notice that the inherited classes Circle, Sphere, and Cylinder all use constructors that initialize the base class, as shown in the following declaration. Each derived class has its own override implementation of Area(). Different shape classes such as Circle, Cylinder, and Sphere inherit the Shape class, and the surface area is calculated for each figure. In this example, the Shape class contains the two coordinates x, y, and the Area() virtual method. It is an error to use the virtual modifier on a static property.Ī virtual inherited property can be overridden in a derived class by including a property declaration that uses the override modifier. ![]() Virtual properties behave like virtual methods, except for the differences in declaration and invocation syntax. to provide specialized accessor behavior. Override auto-implemented property with ordinary property ordinary virtual property with backing field provide specialized behavior if they implement get and set accessors. The following example shows a virtual property: class MyBaseClass You cannot use the virtual modifier with the static, abstract, private, or override modifiers. You cannot override a non-virtual method. The overriding member in the most derived class is called, which might be the original member, if no derived class has overridden the member.īy default, methods are non-virtual. When a virtual method is invoked, the run-time type of the object is checked for an overriding member. For more information about how to use the virtual keyword, see Versioning with the Override and New Keywords and Knowing When to Use Override and New Keywords. ![]() The implementation of a virtual member can be changed by an overriding member in a derived class. For example, this method can be overridden by any class that inherits it: public virtual double Area() The virtual keyword is used to modify a method, property, indexer, or event declaration and allow for it to be overridden in a derived class. ![]()
