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.
This is an amazing site which allow up to 4 people to collaboarate and play virtual instruments over the web in real time. Play a variety of guitars, drums and drum machines and keyboards. There is no sign up needed and you just invite other 'musicians' by sharing the link and begin jamming. Set to 'pro' mode to play using your computer keyboard. Requires Google Chrome.

I aggree that as teachers we need to realize that technology has changed instruction and the way that our students learn and the way that we learn and instruct.
Technology has always changed the way we live. How did we respond to changes in the past? One thought is that some institutions, some businesses disappeared, while others, who took advantage of the new tech, appeared to replace the old. It will happen again and we as educators need to lead the way.
With technology our students brains are wired differently and they can multi-task and learn in multiple virtual environments all at once. This should make us think about how we present lessons, structure learning and keep kids engaged.
Rubbish. The idea that digital native are adept at multitasking is wrong. They may be doing many things but the quality and depth is reduced. There is a significant body of research to support this. Development of grit and determination are key attributes of successful people. Set and demand high standards. No one plays sport or an instrument because it is easy rather because they can clearly see a link between hard work and pleasure.
Information development was slow.
Many learners will move into a variety of different, possibly unrelated
fields over the course of their lifetime.
Informal learning is a significant aspect of our learning experience.
Learning is a continual process, lasting for a lifetime.
Technology is altering (rewiring) our brains.
Connectivism is the integration of principles explored by chaos, network,
and complexity and self-organization theories.
Principles of connectivism:
Learning and knowledge rests in diversity of opinions.
Learning is a process of connecting specialized nodes or information
sources.
Learning may reside in non-human appliances.
Capacity to know more is more critical than what is currently known
Nurturing and maintaining connections is needed to facilitate continual
learning.
Ability to see connections between fields, ideas, and concepts is
a core skill.
Currency (accurate, up-to-date knowledge) is the intent of all connectivist
learning activities.
Decision-making is itself a learning process. Choosing what to learn
and the meaning of incoming information is seen through the lens of
a shifting reality. While there is a right answer now, it may be wrong
tomorrow due to alterations in the information climate affecting the
decision.
So what does this look like? I feel that when I attempt this, evaluators and administrators don't necessarily understand. They want a neat, quiet, well-managed, orderly classroom.
If new learning approaches are required, then why are we still being evaluated in a linear way?
John Seely Brown presents an interesting notion that the internet leverages
the small efforts of many with the large efforts of few.
The pipe is more important than the content within the pipe. Our ability
to learn what we need for tomorrow is more important than what we know
today.

Learning theories are concerned with the actual process of learning,
not with the value of what is being learned.
The ability to synthesize and recognize connections
and patterns is a valuable skill.
knowledge is no longer acquired
in the linear manner
What is the impact of chaos as a complex pattern recognition process
on learning
An entirely new approach is needed.
Chaos is the breakdown of predictability, evidenced in complicated arrangements
that initially defy order.
Meaning-making and forming connections
between specialized communities are important activities.
Chaos, as a science, recognizes the connection of everything to everything.
If the underlying conditions used
to make decisions change, the decision itself is no longer as correct

The ability to draw distinctions between important and unimportant
information is vital.
Behaviorism, cognitivism, and constructivism
do not attempt to address the challenges of organizational knowledge and
transference.
The health of the learning ecology of the organization depends
on effective nurturing of information flow.
This cycle of knowledge development (personal
to network to organization) allows learners to remain current in their
field through the connections they have formed.
This amplification of learning, knowledge
and understanding through the extension of a personal network is the epitome
of connectivism.

An organizations ability to foster, nurture, and synthesize the impacts
of varying views of information is critical to knowledge economy surviva
As knowledge continues to grow and evolve, access to what
is needed is more important than what the learner currently possesses.
Access is not enough. Prior knowledge and understanding is needed. Processing is needed. Evaluation of processing and outputs is needed. Feeding that back into the "system" is needed.
