Lectures Aren't Just Boring, They're Ineffective, Too, Study Finds
sciencehabit (1205606) writes "Are your lectures droning on? Change it up every 10 minutes with more active teaching techniques and more students will succeed, researchers say. A new study finds that undergraduate students in classes with traditional stand-and-deliver lectures are 1.5 times more likely to fail than students in classes that use more stimulating, so-called active learning methods."
...are 1.5 times harder than topics that can be easily turned in to fun activities and games. Voila!

are more likely to fail. so let us design our college curriculum around the retards who drink a 32 ounce mt. dew before class and can't shut off their phone less they miss a tweet. that will punish the people who actually can pay attention and maybe even enjoy the lecture for being smart. the ultimate policy would be that if a frat boy is bored he's allowed to punch a nerd in the arm. that will teach those fucking nerds to pay attention!
...but I liked lectures...
Learning from someone who knows their subject much better than I do who has taken the time to condense a part of their knowledge into a well structured lecture is the thing I miss most when comparing university to work.
I wish to remain anomalous
My accounting teacher at UCSC would give us Sherberts, like you would have orange sherbert between a mulitple course meal to cleanse your palette. It was an unrelated quick discussion multiple times in a class and it worked well.
Choosing the lesser of two evils is a choice for evil.
More it's a symptom of the ADD generation and startlingly shrinking attention spans...
It's a method for transferring words from the prof's page to the student's without passing through the brain of either.

Because we all know that the one single purpose of an education is to train you for a job in the capitalist hell of the labour market. Critical thinking, political activism, creativity, and cultural development and experimentation are all excluded in the Educate Me For A Job model. Of course, the defunding of universities in the USA has caused their costs to go vertical - benefiting the vectoral class of financial extraction via student loans, precluding people from becoming activists, because if they get busted or booted they're stuck with a jillion dollar debt and no degree. Of course, the money for schools has been poured into prisons and warfare, where, again, it benefits the rich, and not much else. So, yeah, get a degree. Get a job. Be a useless debt slave cog in the machine.

Although this study is good for grabbing headlines, the analysis seems a little bit shallow. For one thing, the focus is on STEM (Science, Technology, Mathematics and Engineering) disciplines, As someone who teaches at the college level in both a STEM field and a traditional humanities field, I am well aware that different areas require different methods. For instance, if one is teaching the basics of computational cognitive modeling, then some interactive segments are necessary. However, things work entriely differently if one is teaching, for instance, the history of the philosophy of mind. Another issue I have with the study is (as best I can tell -- I cannot access the original paper) that they do not control for lecturer effectiveness. To put it simply, we all know that some people are better at lecturing than others. That being said, even when teaching say, Cartesian Dualism, there are steps that can be taken to make lecture classes better. For instance, it is widely known that most humans have an attention span of between 10 to 20 minutes. So, it is simple enough to give everyone a break every twelve minutes, or so and tell a story, or some historical anecdote. Similarly, the Socratic approach, asking for input from students throughout the class and then encouraging discussion, can also make lectures much more effective and enjoyable. These are some of the things I do. That being said, I have known people who just drone on in a monotone, in lecture classes. Folks such as that can be utterly tedious. My point here is that unless the effectiveness of the teachers is taken into account, this study cannot be trusted.
One of my calculus professors told us on the first day of class that note-taking was forbidden during his lectures. He argued that, in our quest to write down everything he said, we would inevitably miss important points or misunderstand key concepts. I was skeptical at first, but I soon discovered that he was absolutely right. I was able to absorb much more than I thought by listening intently to what he said, and fully focusing on what he drew on the board. In short, his lectures were effective and valuable.
I never took notes in any other class after that, and my grades never suffered from it. In most classes, the lecture materials were made available for later download anyway! Moreover, the freedom to simply pay attention actually made lectures more enjoyable.
Most lectures I've been to were lectures because it's practically one of the very few ways one professor can address hundreds of people, of course with smaller groups you could do more but then you need lots of assistants and there are study groups that are essentially students learning on their own. Their main purpose is because having regularly scheduled events drags the undisciplined through the curriculum and because socially it doesn't feel like you've been stuck with your nose in a book all day. Personally I felt the most productive way was just crunching through the book until it made sense, but I think that's very individual.

I've attended hundreds of hours of classes, and I've taught graduate courses in engineering. If your lecture has an introduction, preferably with a motivational topic, followed by an outline, a thorough discussion that includes examples for each concept, and then a summary, your students will learn more than if they did not show up and just read the notes.
Of course you need to engage them, ask them questions (I find ways to get them to contribute by offering homework points (capped) for interaction), but that's part of preparing a good lecture. I think most of the lectures that are criticized are those prepared by teachers that would rather do something else.
