In week 9, both lecture and tutorial class were cancelled. By that, Dr. Fariza had assigned one task for us to do in MOOC, which is prototype learning. Prototype is a system analyst and users generally use a prototype to evaluate a new design to enhance precision. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. As we can see that prototype is very relevant to use in teaching and learning, as there will be an evaluation for teacher to evaluate their students’ performance. As, teachers will face the task of evaluating appropriate software to aid the learning process. These is to achieve the effectiveness in teaching and learning process
A prototype is an average or best exemplar of a category, or concept. Prototypes provide a concise representation for an entire group of entities, providing means to anticipate hidden properties and interact with novel stimuli based on their similarity to prototypical members of their group. A prototype learning system is a system of cognitive processes together with their underlying neural structures that enables one to learn a category prototype from a set of exemplars.
A prototype can be in the following forms paper, 3D printing, digital, small model or limited usage product. These prototypes can fall into one of the following area functional, display or a small model. The functional prototype focus on the functions and not on the looks. The display prototype focuses on the looks and not so much on the function. The small model combines both and is a smaller version of the final product. They type of prototype to develop must be decided based on the intended purpose of the prototype, the medium of use and the expected longevity of the prototype.
Today’s lecture we learned about cipher. It was very exciting to learn something new and different from any other knowledge. Therefore, the topic is quite hard for me to understand because it can make us confuse on how to use cipher. In addition, exercises would be helpful to enhance our knowledge about cipher. Even if the topic is quite hard but it can be, understand by getting help from friends, explanation and guidance from teacher.
In cryptography, a cipher is an algorithm for performing encryption or decryption, a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with "code", as they are both a set of steps that encrypt a message; however, the concepts are distinct in cryptography, especially classical cryptography. Codes generally substitute different length strings of character in the output, while ciphers generally substitute the same number of characters as are input. There are exceptions and some cipher systems may use slightly more, or fewer, characters when output versus the number that were input.
Last but not least, one of the benefit that we can get by using cipher in classroom is students can experiment with these topics, see them in action, and obtain a better understanding that would be possible from a theoretical discussion alone
