The communication skills required for successful communication are different for source and receiver. For the source, this includes the ability to express oneself or to encode the message in an accessible way. [8] Communication starts with a specific purpose and encoding skills are necessary to express this purpose in the form of a message.
Online communication increases parents’ understanding of classroom procedures, philosophies and policies. Parents then feel more involved in their child's school and more connected to the teacher. In general, online communication improves parents’ attitudes toward conferencing with teachers and administrators. [10] [11] [12] [13]
Instructional design (ID), also known as instructional systems design and originally known as instructional systems development (ISD), is the practice of systematically designing, developing and delivering instructional materials and experiences, both digital and physical, in a consistent and reliable fashion toward an efficient, effective, appealing, engaging and inspiring acquisition of ...
This pertains to the students’ access to online resources, online systems for access to curriculum and communication, tutoring and assessment. A positive e-learning environment encourages students to interact with their instructors to achieve the maximum benefit from e-learning outcomes. Institution and Service Quality
The term encoding-decoding model is used for any model that includes the phases of encoding and decoding in its description of communication. Such models stress that to send information, a code is necessary. A code is a sign system used to express ideas and interpret messages. Encoding-decoding models are sometimes contrasted with inferential ...
By distinguishing between perceived meanings and perceived encoding strategies, it also gives space to audience's awareness of the 'constructedness' of the text. To conclude, while Hall's Encoding/Decoding model of communication is highly evaluated and widely used in research, it has been criticised as it contains some unsolved problems.
Small signals are digitized with finer granularity than are large ones; the effect is to add noise that is proportional to the signal strength. Sun's Au file format for sound is a popular example of mu-law encoding. Using 8-bit mu-law encoding would cut the per-channel bitrate of CD audio down to about 350 kbit/s, half the standard rate.
Transform coding is a type of data compression for "natural" data like audio signals or photographic images.The transformation is typically lossless (perfectly reversible) on its own but is used to enable better (more targeted) quantization, which then results in a lower quality copy of the original input (lossy compression).
