Instructional Design Principles


After reading this weeks’ material I’m convinced that effective instructional design depends on sensitivity to the cognitive load which, depends on an understanding of how the human mind works.  There are many things about the presentation of the instructional design that I was not aware of. As I began reading Clark and Moreno & Mayer’s article I came to know how pictorial and verbal material is associated with cognitive structures.

I think that a presentation should be broken down into digestible ‘sub-sets’ alternating between a few seconds of narration followed by a few seconds of corresponding animation. Moreno & Mayer found in their experiment (2002) found that people with high-spatial ability have to put less effort in holding and manipulating mental images whereas low-spatial learners may not be benefited of simultaneous presentation. This may require them to devote more time in cognitive processing to hold mental images.
Moreover, segmenting helps in making meaningful subsets of the instructional material. I find when any video/power point is presented with animation continuously, with no breaks between segments; I can make sense from the first segment. But, the additional processes of organizing and integration of information presented in next becomes difficult because my mind is still processing the information presented in the previous segment. Thus, a useful practice is to use the technique that can be called weeding. Weeding reduces load and make the multimedia narration as concise and coherent as possible.

This week gave me an insight on designing my course using multimedia such that it can foster learning.

Selecting an Educational video



The week started with a lot of excitement about the two courses I’m taking in the winter quarter. I read the article “Appropriate Use of Media in Education” on the very first day. The book Building Expertise: Cognitive Methods for Training and Performance Improvement by Ruth C. Clark presents very insightful ideas on the theoretical framework for developing practical instructional methods. I visited her website: http://clarktraining.com/  to read more about her.  There are many informational articles on the company’s blog. 

The article Appropriate Use of Media in Education” discusses different forms of multimedia and their appropriate use. I totally agree with the point that, “. Video can help gain and hold the attention of learners.”
A few points came to my mind. I think these points are imperative while selecting and creating a video  for a classroom or a training.
Learners interest: While creating video learner’s vested interest in the learning, those help them to acquire knowledge or develop new skills, should be kept in mind.
Selecting an educational video:The videos must be selected after watching a range of educational videos/clips, so as to find the best fit for its intended purpose. There is a plethora of videos, ranging from home-made videos to the videos made by professionals. Therefore, one needs to spend time in selecting a most suitable  one.
Dealing with ethical issues: If you find a video on youtube or dailymotion or Vimeo it does mean that it is free for downloading and anyone can use it. A number of times the videos have copyright restrictions and can not be used without permission. For a free video, you always have to provide reference of the video just like we do it for a book or an article. 
Introduction and a summary: While  creating an educational video for a classroom or training, a good practice is to take a few minutes to introduce viewers to the key points and the highlights of the video they are going to watch. Similarly, provide a brief summary of the relevant points at the end.
Length of the video: What is the ideal length of a video. The answer depends upon the viewers’ age and the interest level. Any video between 8 to 12 minutes is ideal. It is best to present long explanations in the form of short clips rather than making a long video. This would retain the attention of the viewers and provide them a better understanding of the concepts being presented.
Quality of the video: The quality of a video matters a lot. While preparing a   video, a close attention should be paid to the sound clarity, lights(if it is being recorded live),and the streaming issues.

How much do we know about our environment?


I keep reading data and findings in the educational field in books and on websites, but somehow I feel that a strong connection between the findings and the changes in education system is lacking. Researchers, practitioners and policy makers should work collaboratively making use of relevant, useful research in improving the education system as a whole.
When I was doing my M.Sc. in Environment and ecology, I had to prepare a research project for the final semester. I was looking for a relevant topic. I happened to visit Centre for Science and Environment located in New Delhi, where I watched a short documentary on sewage and its disposal, which is now available on youtube(http://www.youtube.com/watch?v=1bEZgcGdeZ4). When people were asked the simple questions such as where does drinking water comes from and what happens to the sewage, many of them couldn't answer!

Rather than thinking on the topic the film was made for, I started thinking- how much do our students really know about the environment despite of studying various chapters on Environmental issues in the science books. Thus, I decided to do research on the topic ’Environmental Awareness among high school students’. What I found was that 40 % of the high school students couldn’t answer the simple questions related to the environmental issues because whatever they read was just the bookish knowledge and that was only for answering questions in exams.

 I showed my findings to the principal of the school I was working in. She immediately made an action plan for the next academic year so as to enhance the environmental awareness among the students. The plan included activities such as debates, dramas, tree planting, annual quiz, showing documentary films and demonstrations for students throughout the year.
Thus, my research findings helped in effective restructuring of the instructional methods in environmental science

Game mechanics


Gamigication.org defines game mechanics as the building blocks that can be applied and combined to gamify any non-game context. The purpose of a game mechanic is to present interactivity in a game so that it guides the player towards a fun experience. Game mechanics are more about specifying what there is in the game, how everything behaves, and how the player can interact with the game. Game mechanics are about helping players discover the need of being involved in the game itself. They shouldn’t alone be fun, instead, they should have enough fun to get players to stick with the process and find it useful. Using game mechanics effectively is very important in a game design process.
Some game mechanics have been used for centuries (money, points), whereas  others are relatively new such as feedback loops, virtual gifts and money, loyalty programs and leaderboards. Even in the simple game design mechanics that are technically complex. Some of the simplest games mechanics have been discussed by Greg Siering Indiana University, Bloomington. : http://citl.indiana.edu/news/newsStories/dir-mar2012.php
Another important thing to note here is that game mechanics controls the player’s experience by ‘removing some alternatives and emphasizing others.’ Game mechanics must be placed in opposition to one another to include the element of interactivity in a game. The game using only one mechanic presents no interactivity and no choices. The game mechanics should be woven much like the legs of a tripod, creating a space for interactivity so that players can operate within the game. Will Wright calls it a possibility space which is ‘the sum of all the potential gameplay experiences, sort of the wave function of game design.’ There are several game mechanics (as many as 300) and all games use mechanics. Game designers use different theories and styles to select the mechanics those are ultimately important to the game and to have a fun and engaging experience.
Take a look at Samsung Nation’s website(you need not log in or become a member!) using what different game mechanics to solve Samsung's business problem and bring more visitors to the site. The site was developed with so that consumers can interact with their products and write product reviews to register products that they've already bought. The website uses game mechanics like leaderboards and badges to reward achievements. The whole idea to encourage consumers to buy more products.

Instructor's role in an online class

Elearning


Elearning struggles with high drop out rates. The concept of anytime/anywhere learning often becomes never/nowhere. As many corporations and schools have discovered, the online medium, while still dealing with issues similar to classrooms, faces unacceptable rates of drop outs and failures.
In order to improve student completion rates, organizations have several options: 
(a) Design better learning resources, 
(b) Improve teacher's/facilitator's skills, 
(c) Improve student's capacity to learn through preparation for online learning.

This article focuses on the final point: preparing students for elearning. It is important to note, however, that many of the skills and habits listed here are applicable to any classroom. The divide between classrooms and online is sometimes artificial, and no where is this more true than in student preparation.

Preparation Ecosystem
  • Environment -- students need a certain environment (PC, connection, software) and some preparation needs to be done to make sure that the student has that.
  • Tech skills -- students need to know something about how to use whatever learning system exists. there has to be a way to impart this knowledge.
  • Subject matter skills -- students need to have some pre-requisite knowledge in the discipline to take the course.
  • Study skills -- students need to have the discipline and learning skills to benefit from the course. 
  • Support -- when students run into problems with any of these there has to be a mechanism to a) find out and b) help them through it.
  • Content - designed for interaction - to keep students engaged -page clicking won't necessarily motivate students
  • Learner - Disciplined, motivated to learn, has a need for learning, self-directed
  • Instructor - aware of students needs/concerns and involvement levels, attempts to draw students in to discussions early, organized schedule, provides resources for learners in need of additional learning (remedial)
  • Technology - should play a servant role. Tools should be selected that involve learners and help them to connect with each other/content/instructor. For example chat, discussion questions, voice over IP are useful for connecting students and can be seen as student-centered technologies
  • Organization - focused on learning, time and resources made available, learners supported (through help desks etc.)

Many of these areas are outside of the instructors influence, but still need to be considered or if an area is weak (i.e. limited organizational support), other areas may have to play a more prominent role to ensure learners are prepared and succeed.

Transitional support is critical for classroom to online shifts. Instructors need to provide a transition process. Students expect similar levels of support and direction (as they have in classrooms), and suddenly find themselves in an exploratory environment - a disorienting experience. (Is this a reason for the high drop out rates we have in elearning?) For example, one participant stated, ‘I currently have a group of students, and during a recent feedback request, the responses were heavily centered on "I need an instructor to tell me what to do/think/know". Usually, with most courses I've taught online, the number one concern relates to the changed role of the instructor in relation to student activity - e.g. - the instructor allows students to explore content...rather than giving the answer.’ This is not an issue only in online environments - anyone who takes a similar approach (exploratory learning) in a classroom has the same student responses.

 In a classroom, however, an instructor can still give the answers when students are frustrated with the ambiguity of exploration. Learning online, on the other hand, forces students to explore - putting them at the center of the learning experience.

I should expand my statement in a classroom, during a lecture session students can ask and receive clarification immediately. This obviously isn't the only time learning happens, after all, much of the students time is spent reviewing notes and reading texts outside of the classroom lecture. If classroom students have questions outside of the lecture, they actually have less access to an instructor than do online learners (unless the instructor has an email/discussion forum or chat sessions scheduled).

Online, students do not receive information in lecture format. Information is acquired through exploration, so an instructor is often not present at the time the question arises.  As such the student may have to contact the instructor via email to have questions answered - which is not as rapid as asking an instructor a question during a lecture.
Students online can still receive answers to "ambiguity of exploration", but there may be a time delay versus a student in a classroom lecture (though, as stated above - the time in lecture is a small part of the classroom learning process - students online actually have greater access to instructors the rest of the time).

Preparing Students for Elearning
The type of learning, formal or informal, impacts student preparation. Often, formal elearning (online course) tend to create preparation resources that help students to "take a course" (versus learning). This may perpetuate continued dependence on the instructor or course as the "source" of knowledge. Informal learning is learning that occurs independently and often without direction. Few resources are available to prepare for this type of learning.


The instructor should realize and account for the student experience...ways to address it: offering simple assessments on computer skills needed...introductions at the start of a course (let students post pictures - make it personal), offer links to student resources (including remedial), provide clear schedules, have scheduled instant messaging/chat times, etc.
Student's learning styles will obviously impact their success online. Students may benefit from understanding their own learning style by completing and online questionnaire.
 
Successful preparation for online learning is not significantly different from classroom preparation. As with any new concept, however, it is important for an instructor to communicate how existing practices integrate with a new concept (in this case, learning online).

Consider the following, 
(a) Amount of time to be devoted (usually 10-15 hours per week), 
(b) Degree of interaction required (and tools used), 
(c) Emphasis on self-motivation, 
(d) The use of an instructor (and therefore preparation related to that), 
(e) Entrance Requirements,
 (f) A 'classroom', 
(g)Time-dependency

These may be accurate requirements (and important information) for learning online, but the emphasis is not explicitly on learning - it is how to function effectively according to the manner in which the course is designed. Informal learning (like listservs, Internet searches, or even this "noncourse") have few restrictions and allow learners to perform at their own level of need.
Regardless of the formality of online learning, basic computer and Internet skill, decent connection are a must. These are, however, foundational skills that must be developed in students before learning can occur. They may not be included in every course, but remedial resources should always be listed to direct students to additional help.

Role of the Student
Student preparation is not exclusively the responsibility of the instructor. One of the defining traits of online learning is the increased independence of learners. Online students can contribute to successful learning/preparation through the following:
(a) Awareness - evaluate expectations, assess time needed to complete work, understand motivations/value of the learning, assess personal skills -technical and study skills, 
(b) Orientation - online, a student goes through several stages before engaging the content - the computer, internet, the virtual classroom, software, instructor and students, and finally the content. Different students will enter a course at different levels of preparedness...but in online courses, and instructor should be able to accommodate a student at any level, 
(c) Disciplined - follow course schedule and complete assignments, 
(d) Organized - schedule study time and online time to ensure all course obligations are met, (e) Self-directed - able to motivate her/himself...ask for help when needed, etc., (f) Internal or externally motivated (ie, some requirement or just because it's something that really interests them).

Role of the Instructor
Additional instructor roles are 
(a) Establish rapport with students - make them feel at ease and encourage them to participate, 
(b) Communicate constantly - regular emails, active involvement in discussion forums (but still allow private student-only forums), 
(c) Flexibility - often online learners are adults who have varying time constraints - expect it and accept it, 
(d) The instructor is the creator and curator of the online environment - levels of respect, concern for learning, etc. are all set by the instructor. An attitude that accepts failure as critical to learning is needed
It obviously helps the process if the instructor has taken an online course and knows the frustrations and headaches.

High online dropouts can be (partially) addressed through solid student-centered course design, student preparation (i.e. bringing to the student's consciousness the reality of the online experience), clearly communicated expectations (i.e. instructors), and active instructor involvement in drawing students into discussions.

Role of Learning Styles
Students have different learning styles--characteristic strengths and preferences in the ways they take in and process information. Some students tend to focus on facts, data, and algorithms; others are more comfortable with theories and mathematical models. Some respond strongly to visual forms of information, like pictures, diagrams, and schematics; others get more from verbal forms--written and spoken explanations. Some prefer to learn actively and interactively; others function more introspectively and individually...A learning style model is useful if balancing instruction on each of the model dimensions meets the learning needs of essentially all students in a class."

Tasks to Complete Before Course Start
If this is the first course you've taught online (in this environment), this is what you should do, 

(a) Identify tech support available, 
(b) Take an online course as a student, 
(c) Familiarize yourself with the tools and support available

If this is the first time you've taught this course online,

 (a) Pilot the course - with colleagues and potential students, 
(b) Prepare a "back up plan" for technology/server failure

If you are assembling (some of) the elements of an online course that you or others are going to teach, 
(a) Pilot the course - with colleagues and potential students, 
(b) Back up the course content, 
(c) Prepare or determine support mechanisms for students and instructors, 
(d) Ensure workload and assignments are reasonable, but challenging, 
(e) Verify that copyright/IP concerns have been addressed


Things you have to do for every course even if none of the above apply,
 (a) Prepare learners - send out welcome emails, 
(b) Test links, 
(c) Test assumptions about student readiness and technology access (i.e. are some students on 56k? if so, how will video work? or even complex activities?), 
(d) Plan a course initiation activity - phone conference, chat, in person...this activity should focus on connecting students with each other...and create a degree of comfort

Conclusion
High dropout rates are not a function of the online learning environment - they are a function of poor course design, lack of instructor familiarity of the environment, and learner preparation. Preparing learners to learn online is perhaps the greatest skill that we can offer. In an era of "lifelong learning", skills for acquiring knowledge play a greater role in success than do knowledge concepts (as they often cycle to obsolescence).
