למידה, אינטרנט ... ומה שביניהם

a way of making teaching less subjective, more objective, less experience-based, more scientific. Ultimately, a reform that will make teaching systematic and effective.

Yet policymakers assume that micro- or macro-decisions driven by data will improve student achievement just like those productivity increases and profits major corporations accrue from using data to make decisions.

מחקר: שימוש בטאבלטים משבש את שנת הלילה

בניסוי שנמשך כשבועיים, מספר מתנדבים התבקשו לקרוא מאייפד ארבע שעות לפני השינה במשך חמישה לילות ברציפות, בעוד שקבוצת הביקורת התבקשה לקרוא ספרים מודפסים עם אור עמום. לאחר שבוע, שתי הקבוצות החליפו ביניהן את מטלת הקריאה.

צוות המחקר מצא באלה שהשתמשו במכשירים האלקטרוניים רמות נמוכות של מלטונין - "הורמון החושך" שנוטה לגדול בערב וגורם לישנוניות. לקבוצה זו לקח זמן רב יותר להירדם וחבריה בילו פחות זמן בשנת חלום, הנחשבת כשינה עמוקה. יתר על כן, מי שהשתמש במכשירים האלקטרונים דווח בבוקר שלמחרת על עייפות, גם לאחר שינה בת שמונה שעות.

"We introduce these devices that have medical and biological effects without requiring any health studies on their impact ... They don't have to go through any evaluation like a drug would, for safety and efficacy," Czeisler said. "I think it's time to rethink that."

Those nights were so oppressive that scientists now believe our sleep patterns were radically different in the ages before ubiquitous night lighting. In 2001, the historian Roger Ekirch published a remarkable study that drew upon hundreds of diaries and instructional manuals to convincingly argue that humans had historically divided their long nights into two distinct sleep periods.... Ekirch documents the way the ideal of a single, eight-hour block of continuous sleep was constructed by nineteenth-century customs, an adaptation to a dramatic change in the lighting environment of human settlements. Like all adaptations, its benefits carried inevitable costs: the middle-of-the-night insomnia that plagues millions of people around the world is not, technically speaking, a disorder, but rather the body’s natural sleep rhythms asserting themselves over the prescriptions of nineteenth-century convention....

The flicker of the tallow candle had not been strong enough to transform our sleep patterns. To make a cultural change that momentous, you needed the steady bright glow of nineteenth-century lighting. (עמ' 200-201)

For most of evolution we slept a certain way…. Waking up during the night is part of normal human physiology.

מתי אפשר לחייב הורים לממן טאבלט?

מטרה חשובה - להפוך את הלמידה ליותר מהנה ומותאמת לתלמידים

אנחנו צריכים לדאוג שגם הבתי ספר יהיו שם, אחרת לא נהיה רלוונטיים

הספר הדיגיטאלי גם מאפשר למורים לדעת אונליין מה המצב של התלמידים שלהם

את ההשלכות של דור שהתחנך באמצעות מחשב במקום בספר נוכל לראות רק בעוד שנים

But here’s the thing...no matter where you are in your own transition into a digital reading world we all read more digitally. Emails, Facebook, News, this blog post (unless you printed it off). Just sit back and reflect for a moment how much of your day is reading digital text. Even if you like to read before bed you probably read more online during the day.

"You can write on the text right there," noting that if students aren't allowed to write in textbooks, they can use small sticky notes that come off easily. "You can also flip back and forth very easily, and spatially, there are advantages to print media."

When Pennington's seventh graders took the Smarter Balanced Assessment in English Language Arts on new Chromebooks last April, Pennington didn't teach them how to use the test's annotation feature. Students would have been able to highlight reading passages and take notes on the text to help them answer test questions. He thought it was too complicated for them to learn how to use well in time for the test.

There are a ton of things that are built into most online reading platforms that are never taught to students. Or we try to teach them the same way as we did in a print world and that doesn't work.

Learner Revolution in, Ed Tech Revolution out

New report suggests investors should focus on companies servicing the “Learner Revolution,” which creates pathways of success that guide individual students

Now that venture capital has flooded most of the obvious ideas, the third wave of investment opportunities will be more complex — a revolution that will be more transformative. The set of companies poised to break out will refine and utilize platforms — software, mobile, analytical — to create products and services that will reach out to individual learners, define pathways for their success, and travel down that path with them. Let’s call it the “learner revolution” characterized by accessible, affordable, customizable, transparent services from post-secondary providers, be they old school or new school.

Employers report that would-be workers have the required degrees but lack attributes like ability to work in groups, communication skills, and emotional maturity. They are looking to colleges to be more like placement firms, sending them young, energetic, skilled workers who they can plug in more quickly.

Everyone sees how broken higher education is, and what a bubble it is, but no one knows how to break it.

Investors agree that higher education is currently in a position to go through great change in the coming years, leaving the door open to the refinement of higher education through the learner revolution.

This Will Revolutionize Education

Now that we know best how to make educational videos, and any experience can be simulated in the video setting, YouTube must be the platform that will revolutionize education. I mean the number of educational videos on YouTube is increasing every day.
