Lastly, keep the flowers fresh.

A sense of time is created in discussion boards because they have only that week to complete the work and there is an understanding that the conversations happen in time. But often asynchronous discussions have wide gaps of time between student interactions. One way to bring time closer to the students is to allow them to subscribe to forum threads they are involved in. You can do this in most LMS solutions. Students get an email alerting them to activity in the thread they are active in and it brings them closer “in real time” to the events happening in the class. While this can be overwhelming in larger courses, in a class of 20 or 30 students it usually does not amount to an unreasonable amount of email notifications. One of the most effective ways to bring timeliness to an online course is do a quick recap of previous week, as well as provide a preview of what is expected for the current week. Using screen capture software to go through the course and set expectations is a great way to not only share a bit of yourself with students, but it is a pre-emptive way to answer questions students commonly ask.

it represents their path to the future. As such, it’s difficult to build consensus around any new educational philosophy; experimentation, however well intentioned,2 is perceived as tantamount to tampering with the lives of young people.

The true measure of a language isn’t how it uses semicolons; it’s the standard library of each language. A language is software for making software. The standard library is a set of premade software that you can reuse and reapply.

A coder needs to be able to quickly examine and identify which giant, complex library is the one that’s the most recently and actively updated and the best match for his or her current needs. A coder needs to be a good listener.

Code isn’t just obscure commands in a file. It requires you to have a map in your head, to know where the good libraries, the best documentation, and the most helpful message boards are located. If you don’t know where those things are, you will spend all of your time searching, instead of building cool new things.

Some tools are better for certain jobs.

C is a simple language, simple like a shotgun that can blow off your foot. It allows you to manage every last part of a computer—the memory, files, a hard drive—which is great if you’re meticulous and dangerous if you’re sloppy

Object-oriented programming is, at its essence, a filing system for code.

Where C tried to make it easier to do computer things, Smalltalk tried to make it easier to do human things.

Style and usage matter; sometimes programmers recommend Strunk & White’s The Elements of Style—that’s right, the one about the English language. Its focus on efficient usage resonates with programmers. The idiom of a language is part of its communal identity.

Coding is a culture of blurters.

Programmers carve out a sliver of cognitive territory for themselves and go to conferences, and yet they know their position is vulnerable.

Programmers are often angry because they’re often scared.

Programming is a task that rewards intense focus and can be done with a small group or even in isolation.

For a truly gifted programmer, writing code is a side effect of thought

As a class, programmers are easily bored, love novelty, and are obsessed with various forms of productivity enhancement.

“Most programming languages are partly a way of expressing things in terms of other things and partly a basic set of given things.”

Of course, while we were trying to build a bookstore, we actually built the death of bookstores—that seems to happen a lot in the business. You set out to do something cool and end up destroying lots of things that came before.

nsisted that he had found a gas that could render patients insensible to the pain of surgery.

The idea spread like a contagion, travelling through letters, meetings, and periodicals. By mid-December, surgeons were administering ether to patients in Paris and London. By February, anesthesia had been used in almost all the capitals of Europe, and by June in most regions of the world.

On October 16, 1846, at Massachusetts General Hospital, Morton administered his gas through an inhaler in the mouth of a young man undergoing the excision of a tumor in his jaw.

Four weeks later, on November 18th, Bigelow published his report on the discovery of “insensibility produced by inhalation” in the Boston Medical and Surgical Journal.

There were forces of resistance, to be sure. Some people criticized anesthesia as a “needless luxury”; clergymen deplored its use to reduce pain during childbirth as a frustration of the Almighty’s designs.

Yet soon even the obstructors, “with a run, mounted behind—hurrahing and shouting with the best.” Within seven years, virtually every hospital in America and Britain had adopted the new discovery.

Sepsis—infection—was the other great scourge of surgery. It was the single biggest killer of surgical patients, claiming as many as half of those who underwent major operations

nfection was so prevalent that suppuration—the discharge of pus from a surgical wound—was thought to be a necessary part of healing.

In the eighteen-sixties, the Edinburgh surgeon Joseph Lister read a paper by Louis Pasteur laying out his evidence that spoiling and fermentation were the consequence of microorganisms. Lister became convinced that the same process accounted for wound sepsis.

Lister had read about the city of Carlisle’s success in using a small amount of carbolic acid to eliminate the odor of sewage, and reasoned that it was destroying germs. Maybe it could do the same in surgery.

During the next few years, he perfected ways to use carbolic acid for cleansing hands and wounds and destroying any germs that might enter the operating field.

The result was strikingly lower rates of sepsis and death.

Far from it.

Surgeons soaked their instruments in carbolic acid, but they continued to operate in black frock coats stiffened with the blood and viscera of previous operations—the badge of a busy practice.

hey reused sea sponges without sterilizing them.

It was a generation before Lister’s recommendations became routine and the next steps were taken toward the modern standard of asepsis—that is, entirely excluding germs from the surgical field, using heat-sterilized instruments and surgical teams clad in sterile gowns and gloves.

Maybe ideas that violate prior beliefs are harder to embrace. To nineteenth-century surgeons, germ theory seemed as illogica

The technical complexity might have been part of the difficulty. Giving Lister’s methods “a try” required painstaking attention to detail.

Online learning allows for flexibility of access, from anywhere and usually at anytime—essentially, it allows participants to collapse time and space (Cole, 2000)—however, the learning materials must be designed properly to engage the learner and promote learning.

Cognitive psychology claims that learning involves the use of memory, motivation, and thinking, and that reflection plays an important part in learning.

The development of effective online learning materials should be based on proven and sound learning theories.

Early computer learning systems were designed based on a behaviorist approach to learning. The behaviorist school of thought, influenced by Thorndike (1913), Pavlov (1927), and Skinner (1974), postulates that learning is a change in observable behavior caused by external stimuli in the environment (Skinner, 1974).

Therefore, before any learning materials are developed, educators must, tacitly or explicitly, know the principles of learning and how students learn.

Constructivist theorists claim that learners interpret information and the world according to their personal reality, and that they learn by observation, processing, and interpretation, and then personalize the information into personal knowledge (Cooper, 1993; Wilson, 1997).

The design of online learning materials can include principles from all three. According to Ertmer and Newby (1993), the three schools of thought can in fact be used as a taxonomy for learning. Behaviorists' strategies can be used to teach the “what” (facts), cognitive strategies can be used to teach the “how” (processes and principles), and constructivist strategies can be used to teach the “why” (higher level thinking that promotes personal meaning and situated and contextual learning).

The behaviorist school sees the mind as a “black box,” in the sense that a response to a stimulus can be observed quantitatively, totally ignoring the effect of thought processes occurring in the mind.

Learners should be told the explicit outcomes of the learning so that they can set expectations and can judge for themselves whether or not they have achieved the outcome of the online lesson. 2.  Learners must be tested to determine whether or not they have achieved the learning outcome. Online testing or other forms of testing and assessment should be integrated into the learning sequence to check the learner's achievement level and to provide appropriate feedback. 3.  Learning materials must be sequenced appropriately to promote learning. The sequencing could take the form of simple to complex, known to unknown, and knowledge to application. 4.  Learners must be provided with feedback so that they can monitor how they are doing and take corrective action if required.

Cognitivists see learning as an internal process that involves memory, thinking, reflection, abstraction, motivation, and meta-cognition.

Online instruction must use strategies to allow learners to attend to the learning materials so that they can be transferred from the senses to the sensory store and then to working memory.

Online learning strategies must present the materials and use strategies to enable students to process the materials efficiently.

information should be organized or chunked in pieces of appropriate size to facilitate processing.

Use advance organizers to activate an existing cognitive structure or to provide the information to incorporate the details of the lesson (Ausubel, 1960).

Use pre-instructional questions to set expectations and to activate the learners' existing knowledge structure.

Use prerequisite test questions to activate the prerequisite knowledge structure required for learning the new materials.

To facilitate deep processing, learners should be asked to generate the information maps during the learning process or as a summary activity after the lesson (Bonk & Reynolds, 1997).

The cognitive school recognizes the importance of individual differences, and of including a variety of learning strategies in online instruction to accommodate those differences

The Kolb Learning Style Inventory (LSI) (Kolb, 1984) looks at how learners perceive and process information, whereas the Myers-Briggs Type Indicator (Myers, 1978) uses dichotomous scales to measure extroversion versus introversion, sensing versus intuition, thinking versus feeling, and judging versus perception. In the following discussion, we consider the Kolb Learning Style Inventory.

Attention: Capture the learners' attention at the start of the lesson and maintain it throughout the lesson. The online learning materials must include an activity at the start of the learning session to connect with the learners. Relevance: Inform learners of the importance of the lesson and how taking the lesson could benefit them. Strategies could include describing how learners will benefit from taking the lesson, and how they can use what they learn in real-life situations. This strategy helps to contextualize the learning and make it more meaningful, thereby maintaining interest throughout the learning session. Confidence: Use strategies such as designing for success and informing learners of the lesson expectations. Design for success by sequencing from simple to complex, or known to unknown, and use a competency-based approach where learners are given the opportunity to use different strategies to complete the lesson. Inform learners of the lesson outcome and provide ongoing encouragement to complete the lesson. Satisfaction: Provide feedback on performance and allow learners to apply what they learn in real-life situations. Learners like to know how they are doing, and they like to contextualize what they are learning by applying the information in real life.

Online strategies that facilitate the transfer of learning should be used to encourage application in different and real-life situations.

Constructivists see learners as being active rather than passive.

it is the individual learner's interpretation and processing of what is received through the senses that creates knowledge.

“the process of using a prior interpretation to construe a new or revised interpretation of the meaning of one's experience in order to guide future action” (p. 12).

Learning should be an active process. Keeping learners active doing meaningful activities results in high-level processing, which facilitates the creation of personalized meaning. Asking learners to apply the information in a practical situation is an active process, and facilitates personal interpretation and relevance.

Learners should construct their own knowledge rather than accepting that given by the instructor.

Collaborative and cooperative learning should be encouraged to facilitate constructivist learning (H

When assigning learners for group work, membership should be based on the expertise level and learning style of individual group members, so that individual team members can benefit from one another's strengths.

  Learners should be given control of the learning process

Learners should be given time and opportunity to reflect.

Learning should be made meaningful for learners. The learning materials should include examples that relate to students, so that they can make sense of the information.

Learning should be interactive to promote higher-level learning and social presence, and to help develop personal meaning. According to Heinich et al. (2002), learning is the development of new knowledge, skills, and attitudes as the learner interacts with information and the environment. Interaction is also critical to creating a sense of presence and a sense of community for online learners, and to promoting transformational learning (Murphy & Cifuentes, 2001). Learners receive the learning materials through the technology, process the information, and then personalize and contextualize the information.

Figure 1-6. Components of effective online learning.

Behaviorist strategies can be used to teach the facts (what); cognitivist strategies to teach the principles and processes (how); and constructivist strategies to teach the real-life and personal applications and contextual learning. There is a shift toward constructive learning, in which learners are given the opportunity to construct their own meaning from the information presented during the online sessions. The use of learning objects to promote flexibility and reuse of online materials to meet the needs of individual learners will become more common in the future. Online learning materials will be designed in small coherent segments, so that they can be redesigned for different learners and different contexts. Finally, online learning will be increasingly diverse to respond to different learning cultures, styles, and motivations.

Online instruction occurs when learners use the Web to go through the sequence of instruction, to complete the learning activities, and to achieve learning outcomes and objectives (Ally, 2002; Ritchie & Hoffman, 1997).

"Are we allowed to use ideas from our writing exercise to help us write this paper?" she asked. "Of course," I said. "That was the whole point of the writing exercise—to get you a head start in thinking about how you want to approach your paper." "OK," she said. And then after a brief pause: "Because at orientation they told us we weren't allowed to use our own work twice." "Ah," I said. "That doesn't really apply in this case. And anyway, I don't really mind, in this course, if you take a paper that you've written for another course and revise it for an assignment in here. You just have to make sure that what you turn in fulfills my specific assignment. Other professors might feel differently, though. So I would always ask before you tried to do that."

So why deprive our students of the opportunity to learn those same lessons, by recycling a particular paper from one course to the next?

I can foresee one more objection: What's to prevent a student from recycling the same paper from course to course to course? Students who did so would lose the valuable opportunity to practice their writing—and writing, like any other intellectual or physical skill, requires lots of practice. But—practically speaking—the opportunity to reuse a paper might arise only once or twice in a student's career, thanks to the diversity of our course assignments and disciplines.
