It was an interesting opportunity for me to teach a graduate course at Chiangmai University in March 2009. The 26 students are all studying for a master degree in mathematics education. Some part-time students are doing coursework and need to do an independent study and the rest are full-time students who have to write a thesis. The three-day course aimed to help students with the construction of a research problem.

We spent some time identifying problems related to mathematics education. As the students are all school teachers in primary (grades one to six), middle (grades seven to nine) and high schools (grades ten to twelve), it was not surprising that most of the problems are classroom-related. We spent some time for the students to understand that the research problem is a culmination of their own personal experience and the literature. Their experience with the local situation as well as literature that describes the situation in Thailand (e.g. the TIMSS report) as well as previous studies done in Thailand and elsewhere on related topics are used to generate the content of their research problem.

For example, a student wrote that the primary-level students lack the ability to solve word problems in the topic of time. For example, third graders have difficulty in solving word problems that give the starting time of an activity, the duration of the activity and require students to find the end time of the activity.

This is a problem from the local situation. However, the research problem was still not articulated. For example, the research problem could be to investigate the types of difficulties students have when solving such word problems. A related research problem could be to use the findings from the earlier investigation to design instruction or remediation to help students develop the ability to solve word problems involving time, and to investigate features of instruction or remediation that are able to help students develop this ability.

"Despite resources that are unmatched anywhere in the world, we have let our grades slip, our schools crumble, our teacher quality fall short and other nations outpace us," Obama told the U.S. Hispanic Chamber of Commerce. "The future belongs to the nation that best educates its citizens, and my fellow Americans, we have everything we need to be that nation," he added. The U.S. leader painted the education drive as part of a broader push to promote economic growth in the face of a deep recession and the nation's worst financial crisis in decades.

"In a 21st century world where jobs can be shipped wherever there's an internet connection, where a child born in Dallas is competing with children in Delhi ... education is no longer just a pathway to opportunity and success, it is a prerequisite," he said.

These are words from the President of the USA. In the special lecture I had with all the undergraduate and graduate students of mathematics education in Chiangmai University, I hope the 100 of them in the room can teach 40 students well. In their many years as a teacher of mathematics, they are in the position to bring up a whole generation of citizens who can compete in this type of global economy.

We emphasized on the problem-solving approach, the focus on intellectual competence as well as the concrete/pictorial/abstract approach to teaching students. I was asked where teachers can find problems such as the ones I used in the session. I replied that the problems themselves are not as important as how the teacher uses it. I had demonstrated in the lesson how even computational procedures such as 2/3 divided by 4 can be taught to help students develop and improve their intellectual competence.

In any case there are many good problems on the internet and in moments of inspiration some teachers can come up with interesting problems. If you are one of them, please share

Think of two numbers e.g. 4 and 5. We will do three steps.

In a variation which I did with second graders in New York, they picked two numbers from a stack of cards. They showed the first number but not the second one. Before that they had done the three steps with the two numbers.

Use the 4 and 5 to make 45. Use the 4 and 5 to make 9 (4 + 5). Finally find the difference between 45 and 9.

After demonstrating that if they tell me the first number then I will be able to read their mind for the second and do all the three steps and giving the right answer each time, we began to record the findings.

Many of the participants saw the multiple of nine trick. As I pressed for more observations, another interesting one is how the second digit in the answer is derived by subtracting the first number from ten.

I was reminded again that asking students to explore more ways to often result interesting and outstanding responses.

I did this problem with the teachers group as well as the principals group and on both days we got equally interesting responses except I was surprised that no one in the teachers asked for the reason why the trick worked. One did in the pricipals group.
