Online Education Is the Combination of Convenience and Technology

The evolution of technology and the growth of internet over the past few years have made online education, one of the most promising academic choices for most students. Online education provides knowledge on any subject, topic or stream of interest. Due to the convenience and choices it offers, it is evolving to be more popular than classroom education these days.

Online education encompasses anything that can be taught and learnt. There are different types of online education available on the internet today. They are categorized depending upon the technology used, the method of education and various other parameters. Live distance learning is real time in nature and uses technologies like video conferencing and online classrooms, to give the feeling of a virtual college environment. Students choosing this type of distance learning get to interact with the tutor and fellow students, which connects the student with the rest of the classroom. This makes the learning experience wholesome and enjoyable. Also, interaction is a very important aspect of any course, and getting the experience on interaction real time, makes the learning bottlenecks easy and fast to resolve. Because this is real time in nature, students have to take the classes at a decided time as opposed to scheduling them at their choice of time. Also, it could be a little difficult for students at different time zones to come online at the decided time.

Online education that does not take place in real time is known as asynchronous online education. Educative materials are mostly stored for later access of students. Interaction happens mostly through student forums. Students post the problems and questions on the forum and tutor answers them at a later point of time. Course materials are posted on the internet, and can be accessed by the students at any point of time. Also, tutors can record the videos of lessons and can post it on the forum. This method of distance learning enables students to schedule the lessons whenever they want to, and decide the pace of their degree.

Handheld Technology For Science Education - Graphical Datalogger Probeware and Sensors

Data collection using modern data logging systems is revolutionizing the face of school science labs around the world. Information that was previously tedious to collect, subject to much guess work and often difficult for many students to visualize or draw any actual learning value from, can now be displayed in a clear, graphical and easy to understand fashion with graphical data logger technology, also referred to as probeware with sensors, designed specifically for science education.

Using probeware technology and interfacing directly with the computer, these data logging devices collect information from a wide array of sensor types and assimilate it into easy to interpret, graphical representations. This information can be monitored while it is being collected or stored for future use. This makes the compilation of reports and presentations much easier.

The real-time nature of the displayed data is also a great plus for these devices as information can be monitored as they are picked up by the sensors. This allows for a far more immediate view of the results of any experiment and a more accurate understanding of the implications and causes of the data that is being collected.

One of the data logging devices that offers considerable benefits in the realm of physics, biology, environmental science and chemistry is the SmartSense Vision. This is one of a new family of compact, graphic dataloggers that can assimilate data simultaneously and is compatible with a broad range of sensors.

These units feature a touch sensitive, full color screen to display internal software that mimics the PC software. This particular device has a USB port so users can connect most peripherals such as a mouse or keyboard. Data stored can also be printed directly from it or copied onto another memory device via the USB port.

The most advanced of these new graphic dataloggers can also display directly through a projector or monitor for greater visibility and exposure. Sensors attached to the unit are auto identified and calibrated which makes the system as a whole quick and easy to set up and use.
