Science, math and engineering departments at many universities are abandoning or retooling the lecture as a style of teaching, worried that it's driving students away.

Last month, we began inviting students across the countries to fire up their Web cameras or camera-phones to send us video commentaries about whether lectures work for them. Below are highlights from the first batch of submissions, which are full of frustration with "PowerPoint abuse" - professors' poor use of slide software that dumps too much information on students in a less-than-compelling fashion.

iTunes U has, up 'til now, been just that: files to download. Although most of the content is lecture podcasts (in video or audio form), there have also been course documents and slideshows as well.

When I read this article and what they are doing, I shuddered. I come from a background where distance education courses are specifically re-designed for distance learners. In particular, they are designed to allow students to interact with instructor and other students any time and anywhere. They are designed to ensure that distance learners have adequate support and help from their instructors. This takes longer and means thinking differently about how the course is designed and delivered - not taking the standard classroom model and multiplying it to extra students. Now I'm not against introducing new methods of design to accommodate or exploit new technology, but it must meet certain criteria. Does it at least maintain and if possible increase the interaction between student and instructor and between students? Do all students have equal access to service within the course? Does it provide the flexibility and access that distance learners require? Do students learn better?

Part 1 of edited highlights of a talk given by John Hattie who has led a team at Auckland University, New Zealand which compares the effect on learning of over 100 classroom interventions. This section looks at methods with negative, or very low effect sizes. Hattie points out that most educational debate is about things which do not really work well.

In entry-level courses it's often a struggle to get students to see that the content has larger significance and intriguing aspects. In most science textbooks, for example, only well-established facts are presented, and they are supported by equally well-know research studies. Textbooks don't usually identify areas of inquiry where the questions have yet to be answered or the findings so far are controversial. And yet often, this is the content most likely to interest students. But can you expect beginning students to read original sources, like research studies? Could you expect them to answer test questions about those articles? A biology professor reports on his experience using research articles and asking test questions about them in an undergraduate course for students majoring in life sciences. Students were assigned a research article to read-the article was relevant to content being covered in class. It was posted on an accessible website. Sometimes the article was discussed during the lectures and sometimes it was the topic of a tutorial session (these were large classes that included tutorial sections). Either way the students had access to the articles before and during the assessment activity.

So what's wrong? In short, the common thread I see throughout all the failures is quite simply a lack of empathy. There is no authentic encounter with students, or what Martin Buber called "a genuine meeting." When we use all the right methods, and we still fail, it is most likely because we are encountering our students as objects and not as the rich and complex individuals that they are.

Student evaluations and a heavy reliance on them can be problematic for several reasons, the authors of the paper argued. Departments can misinterpret these evaluations by comparing averages for all instructors in similar courses, which can be a very imprecise measure. Moreover, instructors may alter their teaching methods solely to boost their student evaluation scores. The potential problems, according to the paper. Teachers might try to entertain and not educate. "To instructors, generating positive student answers to questions about overall effectiveness and communication skills may smack of entertainment and dumbing down," the paper says. Professors might try to drive out malcontents or otherwise unhappy students before the end-of-semester evaluations. Instructors might avoid attempts at innovation and play it safe in the classroom just to get better evaluations.

Why College Students Leave the Engineering Track http://economix.blogs.nytimes.com/2012/01/20/why-students-leave-the-engineering-track/ Actually another study of science students asked the students why they were transferring or dropping out of science majors, and the number one reason cited was poor teaching: http://www.science20.com/news_releases/6_researchers_take_science_education "when college students abandon science as a major, 90 percent of them do so because of what they perceive as poor teaching; and, among those who remain in the sciences, 74 percent lament the poor quality of teaching" via http://edtechdev.wordpress.com/2009/08/31/50-examples-of-the-need-to-improve-college-teaching/

Today we move that effort forward by providing a number of videos that help us better understand how these devices work and what we can do with them in the classroom.

I'm finding in current iTunes U courses and collections, each collection tends to have a lot of apps and items embedded that cost money (even if a free alternative exists or is already installed.)

Who ultimately ends up on top has huge implications for educational technology leaders, who must determine which company is the best fit for their needs, and at a cost their districts can afford in still-difficult budget times. Complicating those decisions are changes in the technological landscape that are raising questions about the long-term educational relevance of interactive whiteboards. Do classrooms really need them in the age of iPads?

All of us - teachers, parents, and students - retain outdated ideas about learning that are based largely on our previous experiences in school. Modern brain science has helped steer us in the right direction. Here are a few of the biggest myths:
