This is what Dave Ramsey of Financial Peace Revisited thinks about this saying: “That stupid saying "What you don't know can't hurt you" is ridiculous. What you don't know can kill you. If you don't know that tractor trailer trucks hurt when hitting you, then you can play in the middle of the interstate with no fear - but that doesn't mean you won't get killed.” I guess we should fix that saying then to "What you don't know can hurt you". But in education, we could go further and write a saying that provides a useful message: "What you think you know but actually do not know will hurt you."

What is the best way to learn? This is an important question for educators. Some are attracted to the notion of inquiry-based learning, in which students are given the opportunity to solve problems on their own. The notion of collaboration is also attractive. In this case, it is hoped that students learn from each other when they work together. Lastly, there is the traditional option: learning by example. A paper scheduled to be published in the Journal of Educational Psychology addresses this question by performing a controlled experiment in Year 7 mathematics classes in an Indonesian school in Magetan, East Java. Their results suggest that learning from examples works best. In addition, students learning collaboratively is found to be somewhat detrimental when students are learning from worked examples.

Elementary pupils from Hong Kong score high in international standardized math exams. Hong Kong has placed second in the most recent TIMSS exam for grade 4 mathematics. It is therefore interesting to examine what teachers' characteristics correlate with student performance in schools in Hong Kong. Since this is a high performing region, one can just imagine that teachers in these schools mostly have high subject matter knowledge (SMK) as well as pedagogic content knowledge (PCK). Still, things are seldom homogeneous so it is possible to find variance within Hong Kong students and teachers in terms of mathematics performance.

"When you enter this school, you are scientists, you are explorers, you are important, you are loved, you are respected, you are a friend, you are the reason why we are here, love", - Mason Crest Staff. It is so much more than just a corsage of slogans. These words breathe a spirit of a genuine positive school climate in the elementary school where my children study. It is true that there are gaps that still need to be filled with regard to our knowledge of how to improve school climate but there is no doubt that what happens inside a school affects learning outcomes.

No curricular reform would work without addressing first the basic needs of school children. When kids have to climb cliffs and cross a river using a bamboo raft, their safety needs to be addressed first. A video showing what some Filipino children have to do just to attend school has been loaded on YouTube by Kyle Jennermann more than a year ago. The video has been viewed more than a hundred thousand times. Finally, the Philippines government has taken the right step in improving basic education by providing a safe bridge for school children to cross in Barangay Lingating in Baungon, Bukidnon.

My son's daily schedule in his elementary school includes an hour-long period for recess and lunch. At the end of the day, he may not easily remember what he had for lunch, but what happened during recess is something he could recall without difficulty. In fact, he tells me that he has scored a dozen goals in soccer since the start of the academic year. He may not share with me readily what transpired during math period but I am certain that at the end of the day when I pick him up from school I will be briefed on the highlights from the day's recess. Recess makes my son's day in school. It is his favorite period. And it is the period that has helped him a lot academically.

"How does allowing a student to opt out of a program to provide him or her with assistance teach responsibility? If a student is truly going to enter a sink-or-swim situation in higher education, the best preparation is to teach the student to swim — to provide the student with the knowledge, skills and habits essential to success in that situation — rather than allow the student to sink first in high school", Richard DuFour writes in his book In Praise of American Educators: And How They Can Become Even Better. Jay Mathews of the Washington Post took notice of this statement and called it "brilliant" in his column on education. But there is one comment that caught my attention on Mathews' article. Part of it says "We make too many excuses in modern America, we give too many second chances. Penalties and consequences exist for a reason. Carrots alone don't work, you need the stick too. And sometimes people need to hit bottom before they get better. There is nothing more pernicious in education than this self-esteem crap and we need to get rid of that and start making our kids stronger by telling them the truth when they're messing up." Hitting rock bottom is one of those sound bites often used by some to give advice for recovery. It is a wrong advice. Even with drug addiction, David Sheff says, "Waiting for someone to hit rock bottom is a dangerous concept. Experts advise parents of it, but the reality is that studies show people who are coerced into treatment by way of their parents or even the legal system have an equal chance of doing well as those who ‘choose’ to be there." Hope presupposes a glimpse of success and can not emanate from unmitigated darkness.

At the end of the semester, students in universities are given the opportunity to evaluate their instructor. How students' evaluations correlate with a teacher's effectiveness is only expected to be weak. In fact, a study from Bocconi University suggests that students' evaluation of an instructor depends on "meteorological conditions". A teacher tends to receive poorer evaluations on either a cold or rainy day.

For the past six years, the budget for building classrooms in the Philippines has been rising every year. Yet, classroom shortages still exist. The image of about sixty second grade students cramped inside a former toilet as they listen to their teacher Leonora Jusay remains, even with billions of pesos assigned to alleviate the overcrowding of schools in the country.

Neuroscience has shown that when we see people suffering, we in fact feel the pain firsthand. The same regions in our brain that increase their activity when we get hurt are likewise the same regions activated when we witness another person in pain. This is indeed the first step in empathy, to feel what others feel. Functional magnetic resonance imaging has demonstrated that this happens as well with children. Empathy appears to be universal. How we cope is where we diverge. We either blame or feel guilt. And in a study by Leith and Baumeister, they found that "Guilt-prone people and guilt-dominated stories were linked to better perspective taking (measured by changes between the two versions of the story) than others. Shame had no effect. Guilt improved relationship outcomes but shame harmed them."
