Cognitivism believes that knowledge is organized. By using various mental representations, human minds are capable of structuring knowledge and generating limitless further representations. For instance, here is a driver’s license “1B1684T”. What is the best way to remember it? One can repeat it continuously and probably will remember it. However, the most effective way is to use “association” skills to form a structure and store the structure in one's memory. One might say “Number 1 in Birmingham (1B). Then one might identify the relationships among numbers. 16 is 2x8. 8 is 2x4 (1684). “T” can refer to a “teacher” if it happens that one is a teacher. Now it is a lot easier for one to remember this driver’s license.
Cognitivism views learning as knowledge transmission. It is the teacher-centered approach. The teachers’ job is to facilitate the formation of cognitive structures in learners’ minds. The teacher uses various mental representations to facilitate knowledge transmission. These methods include "association", categorization", "comparison", "contrast" and etc. I need to emphasize that we do learn from good lectures, although we do not learn only from lectures. A successful classroom keeps a good balance between the teacher-centered approach and student-centered approach. I remember a physics teacher who always used daily examples to illustrate difficult concepts. In one class, he said: “You are thirty. The water in the cup is hot. What do you often do? You blow at it for a while before you drink it. It shows that temperature is related to flow of air.” Years later, I still remember his lectures.
The following postings are from discussions in previous course. The group conducted a discussion on various cognitive strategies to facilitate student learning of course materials. These postings are about a memory enhancing strategy – Mnemonics.
Posting #1
Mnemonic devices are an important Cognitivist tool. I still use mnemonic devices to remember information all the time. Can you think of an example of a mnemonic device for your content area? This might be something useful for the lesson plan for this unit.

Mnemonics is a great memory enhancing strategy that involves teaching students to link new information that is taught to information they already know. It doesn’t require a wealth of material and does not require extensive planning (Mastropieri & Scruggs, 1998). Even though students in early grades are not usually expected to learn and recall as many facts as older students, they are involved in a number of activities that involve making associations that could use mnemonic devices. One example I can think of is the link between letters to words; such as “a” stands for “apple” or “f” for “flower”. Another example is teaching students that the shape of the letter “s” looks like a snake, which also begins with that letter. I have also used mnemonics when teaching new vocabulary by having the students think of what the specific letter formation of parts of the new word remind them of. One example is- the word medicine has two letter “i”’s and those two “i”’s resemble two pills. Mnemonics helps me memorize important information needed for tests. I use this strategy frequently!

My content area is English. I only remember one really memorable mnemonic device. A professor in college did a demonstration to illustrate the definition of melodrama. It might be hard to describe in text, but I'll try. She folded up a piece of loose leaf paper, accordion style and pinched it in the middle (so it looked like a bow). Then she held it above her lips like a mustache and said in a deep voice, "YOU MUST PAY THE RENT!!!" Then she moved the paper bow to the top of her head and said in a high pitched voice, "But I can't pay the rent!" She went back and forth like this for a while. Obviously she looked like an idiot, but she did effectively demonstrate the term melodrama. Also, it was hilarious. The humor only made it easier for the students to learn! I have never forgotten that demonstration...or the definition of melodrama!

I experienced a terrific mnemonic device yesterday while observing a US Government teacher at Hoover High School. She is teaching her twelfth grade class the 27 amendments She went through many suggestions, but when she got to 18 and 21 this was her advice: In the US it is PROHIBITED for 18 year-olds to drink alcohol, therefore remember that the 18th amendment was the Prohibition amendment. Then when a person turns 21 the are allowed to drink alcohol so the ban has been repealed; therefore, the 21st amendment is the Repealing of the Prohibition amendment. I had never before heard it said like that, but I bet I will never forget it. Plus the way she presented it with fun and vigor, class movement, her movement, etc. Impressive! The whole class was mnemonics to remember, and not a student probably realized they were even learning!

Mnemonics are a great strategy for students to enhance their memory. I once did a lesson on the order of operations in math. I used the famous "Please Excuse My Dear Aunt Sally" to teach the order. Students were quick to learn the order and had no problems doing the math that I put before them. I also used a mnemonic device to teach the planets. "My Very Elderly Mother Just Served Us Nine Pizzas" of course is the phrase in which most people use to remember the planets. I introduced this to the students and then challenged them to come up with their own phrase. The results really surprised me. Then when I quizzed them the next day, I asked the students to write the names of the planets in order and said I would give extra credit if they could write their original phrase. Again I was surprised, because every student remembered their phrase and the planets.
By viewing cognitive learning software listed in the course, you might notice that cognitive learning software encourages students to identify patterns and generate patterns. Students can also use the software to create their own pattern exercises. Graphic organizers are efficient concept mapping tools that make it easier for students to organize and structure information. Graphic organizers allow student to visually display relationships between information and thus create a mental representation to be stored in the mind.
Computer tutorials take cognitivist approaches. I have had a positive experience with a piece of tutorial software. I learned Lotus Spreadsheet from this piece of software. It was my first semester as a graduate student in the United States. I was feeling nervous and uncertain. I took a statistics course and needed to use the software in my class. By chance, I located a piece of software which tutored Lotus Spreadsheet. I started the tutoring at night. I liked the software. I felt very relaxed in this learning environment. There was nobody around me. I could concentrate on my learning. The computer tutor was tireless and patient. I could have it repeat the tutoring as many times as possible. Though patient, this tutor was sharp and strict. A “warning” beep would pull my wandering thoughts back onto the right track. By the time the class met again, I was quite ahead of the class in my skills in operating Lotus Spreadsheet.
Cognitivism is teacher-centered approach. All the learning activities are designed and controlled by the teacher. Students can be grouped together to do exercises, for example, to play a simulation game. However, they are mainly following the instructions given by the teacher or the software program in completing the task. There is very limited knowledge construction taking place. Cognitivism does not necessarily exclude group work. It depends on what students do in groups.
In conclusion, I think all the groups did well in the discussions on cognitivism. I hope these discussions help you design your cognitivist lesson plan and the teacher support material

Thoughst on Behaviorism
The importance of drill and practice relates to the notion of automaticity. In order to perform complex intellectual tasks such as reading, writing, and solving math problems, it is essential that learners master subskills to the level of automaticity. It means that learners should be able to perform these subskills without thinking or automatically. If one writes, one needs to master spelling of vocabulary and sentence structures. To solve complicated math problems, one needs to master basic calculating skills and formulas. Once I talked to my friend who was studying for her Ph. D. in math. She told me that math did involve lots of memorization. Please do not misunderstand. Drill and practice is a component of learning, not everything about learning.
One’s working memory is limited in capacity. One can only process limited numbers of mental operations at a time. It affects the operation of higher order skills if too much memory is devoted to operating subskills. The mastery of subskills will free working memory so that more working memory can be devoted to operate higher order skills.
Comparing with paper drills, computer drills have the following advantages:
Computer drills are fun. It is boring to be drilled. No one likes to be drilled. Computer drills integrate games into drill and practice. While the learner is playing games, the learner is being drilled.
Computer drills provide immediate feedback. Time is always an issue to drill students in classroom settings. With too many students in class, the teacher finds it difficult to provide adequate time to drill each student. If students drill themselves, they might make mistakes without being corrected immediately. The mistake might perpetuate itself. Computer drills provide learners immediate feedback. Mistakes are corrected immediately.
Computer drills remove psychological barriers in student drilling process. If students are drilled in class, it is quite humiliating for students to make mistakes in front of the class. Computer drills can remove this psychological barrier. No one knows that the learner makes a mistake, but the computer.
Computers never get tired. Students can practise and repeat a skill as many times as possible.

How to Write a Reflective Learning Blog?
A reflective learning blog is an electronic reflective learning journal. Some students asked me what they should be writing in their reflective learning blogs. This questions prompts me to write this new entry in my teaching blog – how to write a reflective learning journal.
The purpose of keeping the reflective learning journal is to help you learn and grow. Confucius says "Study without reflection is a waste of time; reflection without study is dangerous". Through keeping a reflective learning journal, you make learning personal, meaningful, and connect learning with your prior knowledge. Through reflective writing, you gain new insights about what you have learned. Writing forces you to make your thoughts visible and examine your inner thoughts closely. Through writing, ideas become clearer and lens of focus becomes sharper.
The reflective learning journal is to record your reflection and growth. Dennis List emphasizes that a reflective learning journal is NOT these two things:
(1) a summary of reading materials. Instead, you should focus on your reaction on what you have read.
(2) a learning log. A reflective learning journal is not a learning log for you to record events. It records your reflection, thoughts, and observation about events.
In your reflective learning blog, you can analyze your learning experiences, discuss how you would apply your learning to your teaching, re-evaluate your previous assumptions, raise questions, challenge a theory or a practice, and present new thoughts as the result of your learning. Dennis List provides a long list of items one can write in the reflective learning journal. This list gave me ideas to frame the following questions. These questions should guide you through your journal writing.
What was the most important/interesting learning experience (e.g. course reading, group discussion, or lesson plan development) for me and why it was important/interesting to me?
How would I apply what I have learned in my future teaching?
What was my previous assumption (a theory or a practice), and how did the learning make me re-evaluate my assumption?
What questions would I like to raise about a piece of reading material, a practice or a common belief?
What would I like to challenge (e.g. a theory, a practice and a common belief)
What observation would I like to present about a particular learning event?
What new thoughts do I have as the result of my learning/reading?
I hope you find this blog entry useful. Happy blogging.

How to Achieve Success in an Online Course?
This is my teaching blog for this course. I hope this blog can offer another communication channel to assist you in this course. This blog will be the forum for me to offer tips, strategies and guidance so that you can be successful in this course.
It is normal for students to experience a certain level of anxiety in taking an online course, especially if it is the first online course you are taking. However, you will gain experiences navigating and functioning in the online learning environment as the course moves along. Here are a few suggestions for you. Hopefully, you find them useful.
1. Lots of students think that the online course takes less time and efforts. It is a misconception. Contrarily, you need to spend more time and efforts in the online course. The online course is text-based. We write a lot slower than we talk. For example, it takes more time and efforts to participate in class discussions online than in face-to-face discussions. However, the pay-off is the flexibility of time and place. You do not need to travel to the campus for most class sessions and you can choose the most convenient time for your learning.
2. You need to log in at least twice a week. Ideally, you should log in every other day to keep yourself well informed of all the development in the course. When a mail is sent through the blackboard, it does not go to your Internet mailbox, it remains in the blackboard vista. Therefore, you do need to check your mail from time to time so that you do not miss any information. You do not need to stay on line for two hours and a half at one time. You can space your time between log-ins.
3. Come to face-to-face meetings. Bring all of your concerns and problems to face-to-face meetings. Face-to-face meetings are helpful in clarifying student confusions. You’ll learn new technology skills that you’ll need to complete your assignments. You will also have opportunity to meet your group members face-to-face to discuss group projects.
4. Read, read, and read carefully. The online course is text-based. Therefore, you need to spend time reading all the instructions carefully. Pay attention to the deadlines for the assignments and class discussions. Points would be deducted for late assignments. Worse, once a discussion closes, no one is allowed to post any more. Read carefully about the instructions for each assignment and discussion. Follow instructions. All the assignments are posted online for the whole semester, which should help you to plan your time and work throughout the course.
5. Communication is the key. There are various ways to communicate with me. I have set up a "Faculty Office" where you can post your questions. You can e-mail me if you desire. All the questions and mail will be answered within 48 hours.
6. This is a discussion-based course. All the assignments are based on class discussions. Without participating in class discussions, you will not be able to do your assignments. We also have group projects. Your discussion performance is seriously evaluated. Follow discussion rules. Rules are posted for each discussion activity.
