Everything you thought you knew about learning is wrong

In a recent article on Wired, Robert Bjork, the director of the UCLA Learning and Forgetting Lab, outlined some important points about learning and how our best perceived ways of learning is flawed.

Should you focus one skill at a time ?

People tend to try to learn in blocks, Bjork said. Mastering one thing before moving on to the next.

Bjork recommends “interleaving”. Instead of spending full hour working on single task, such as a tennis serve, you mix in a range of skills like backhands, volleys, overhead smashes, and footwork.

This creates a sense of difficulty, Bjork said. And people tend not to notice the immediate effects of learning.

Bjork believes that although you may not make appreciable leap in one skill immediately, but over time, the sum of these small steps is much greater than the sum of the leaps you would have taken if you’d spent the same amount of time mastering each skill in its turn.

Bjork explains that successful interleaving allows you to “seat” each skill among the others. “If information is studied so that it can be interpreted in relation to other things in memory, learning is much more powerful,” he said. There’s one caveat: Make sure the mini skills you interleave are related in some higher-order way. If you’re trying to learn tennis, you’d want to interleave serves, backhands, volleys, smashes, and footwork — not serves, synchronized swimming, European capitals, and programming in Java.

 

Do you study in the same place everyday?

Your study location matters. Prof. Bjork believes that studying in one place is great as long as you are required to recall your memory in the same place. Instead, studying in multiple places like the dorm, a different room at home, library etc. will condition your brain to recall information just about anywhere.

 

Do you revise too quickly?

Bjork says that if you study, wait and then study again, the longer the wait, the more you’ll have learned after this second study session.

When we access things from our memory, we do more than reveal it’s there. It’s not like a playback. What we retrieve becomes more retrievable in the future. Provided the retrieval succeeds, the more difficult and involved the retrieval, the more beneficial it is.

What is important here is the concept of “spacing”. Students benefit from starting early such that there is more time to learn, revise and practice complicated lessons and also space them for enhanced learning.

 

Do you spend time taking notes while you should be listening?

Many students take notes during classroom sessions while the teacher explains a theory or a concept.

Along these lines, Bjork also recommends taking notes just after class, rather than during — forcing yourself to recall a lecture’s information is more effective than simply copying it from a blackboard. You have to work for it. The more you work, the more you learn, and the more you learn, the more awesome you can become.

Finally, Bjork says

Forget about forgetting, People tend to think that learning is building up something in your memory and that forgetting is losing the things you built. But in some respects the opposite is true. See, once you learn something, you never actually forget it.

Please share your thoughts on the topic and what in your opinion works best.

Low self-esteem ?

Low Self-Esteem ?

Low self-esteem has an impact on every part of your daily life. It makes you withdraw form normal activities. If you feel that you are lesser than others , others will see the same in you as you exhibit. On the contrary if you have good self esteem and feel worth being around, others pick up the same. So please think and ACT NOW.

Ten Methods To Overcome Low Self-Estee

1. Speak Up: Your own voice is great, your idea is good and you have a right to express. Just Speak up, and do not be afraid to voice your opinion. Participate in the conversation, and let others know that you are there and you have something to offer. Others might not appreciate your opinion openly but they do take a note of it. If you get a direct appreciation you will just be surprised at how important your views are to others. Speak up , you are going to gain….if not , no loss because it was your opinion.

2. Stand Up Straight: Standing up straight is not only better for your posture it also displays confidence. When you have a slumped appearance, you portray the image of someone who is uncomfortable, and depressed. Making a conscious decision to correct your posture will immediately transform your image.

3. Carry Yourself With Pride: Just as it is important to stand up straight, you should also walk with pride. Overcoming low self-esteem truly starts with your outward appearance. Walk tall, do not shuffle your feet, and put a spring in your step. This will give you an energetic appearance that others will perceive as confident and powerful.

4. Give Yourself A Pep Talk: Whenever you are feeling a little down, or lacking in self-confidence, give yourself a quick pep talk. Remind yourself of all of your great, unique qualities, and strengths.

Have self affirmation exercise…  Say “I am honest”  ….and shout YES, Say “ I am right”….and shout YES….SO on … any number of your traits.

5. Dress Well: When you look better, you feel better, and this principle applies to self-esteem as well. Take a bit of time to plan an outfit that is flattering, groom yourself, and always take pride in your looks.  Please do think about the season as well….

6. Get Some Exercise: Getting some regular exercise can really make in difference in overcoming low self-esteem. Not only will your physical appearance improve, which will make you feel better about yourself alone, you will also feel better due to the endorphins, the  “feel good chemicals” that are released during your workout.

7. Put Yourself Out There: You cannot truly work at overcoming low self-esteem if you do not put yourself out in the world. Do not hide in corners or take an excuse to do so or remain silent.

Compel yourself in a position where you have to speak up, and make your presence known.

8. Be Grateful For What You Have: Instead of dwelling on what you do not have, or what you think you want to have, focus on what you do have.

Family, love, health, and personal strengths like your charm, education, talents, your parents position if need be, are a few examples of what you should remind yourself to be grateful for everyday

9. Be Positive Toward Others: People with low self-esteem often tend to be quite negative. Practice being positive toward others by regularly offering complements to co-workers, friends, and family members.

Do not take part in behaviors such as gossiping, back biting, being jealous, discouraging, etc.

By making a commitment to break free of negativity, people will start to feel better around you and will genuinely want to spend time with you.

10. Help Others: Whenever and whenever you can, step up and take an active role with others. Offer help in any way that you can. Donate your time to become a mentor, or offer to help a fellow co-worker with a project. You will feel happier, have more confidence when approaching people, and in turn you will open yourself up to many new experiences.

These simple tips can do wonders to help build self-confidence and in overcoming low self-esteem. Try to complete one or two of these steps at a time so that you do not feel overwhelmed. Remember, this process will take little time and practice.  So relax and follow the tips each and every day for a period of time until it becomes a habit.

Thanks people,

God Bless you all.
