I received my BS in Physical Chemistry from Chongqing University, China and my Ph.D in Biochemistry from Miami University, USA. I have extensive teaching experience in college-level General Chemistry, Organic Chemistry, Biochemistry and Plant Biology as I served as a Teaching Assistant in Miami University for 4 years. I know their backgrounds and ways to improve their grades. Right now I am tutoring AP chemistry and Chemistry Olympiad in an education institute in the Bay Area. During my Ph.D, I did independent research in biochemistry, molecular biology, cell biology and plant biology. I also mentored undergraduates in developing research proposals and projects for fairs/conferences. My goal is to help students to understand, summarize and prepare for their exams to obtain desired results in a reasonable period of time. During my teaching, I strive to foster an exploratory atmosphere by asking questions and knowing their backgrounds/weakness. I try to make connections between... read more

Whatever subject you are studying, a good approach is to come home at the end of the day and review your notes. Anything you don't understand, formulate into a written question so you can check on it yourself or ask your teacher or tutor for help understanding. Waiting till the night before an exam will likely make you nervous. It will be hard to have enough time to prepare. Study a little each day, then, cramming can be helpful. Be sure, however, that you eat and rest well. Especially the night before a test, go to bed early. Eat a good breakfast before an exam, too. Review a bit every day, then, the night before, quickly review what you've worked on, then, get a good rest. Maybe, you will have a miracle because you have prepared yourself a little bit every day.

A very easy science demonstration that sparks interest in students is sprouting beans. Take a piece of cardboard. Lay it on a plate. Add some water to the plate to be absorbed by the cardboard. On the cardboard lay 4 or 5 dried beans which can be navy beans, lima beans, black-eyed peas, or similar. Leave the plate with the wet cardboard and beans on the counter. It will take about 4 or 5 days depending on the weather for the beans to sprout. First you will see the beans swelling up as they absorb water. Then you will see a tiny root coming out of the bean. Later you will see a tiny stem. Place the plate in sunlight or at least daylight. This experiment can be kept over a week or two or maybe longer for students to observe. Suggest that they try it at home, too. This will stimulate their personal interest in science. Children and older students are always excited to do science projects. It's a lot of fun to observe the beans each day to see what kind of progress they are... read more

As teachers and tutors, we need to be ready for any question or answer we receive from students. This is due to several factors, including, among other things, learning difficulties, inattention, unfamiliarity with the subject, material missed during an absence, or student playfulness. Therefore, we have to be understanding and patient, using the occasion as a teaching opportunity. In the following story, how should Mr. Parks react? Family Membership Mr. Parks is the Biology teacher at Brown County High School. One day in Botany class he held up a jar of Pedro's Taco Salt, showing the front label to the class. "What is this?" he asked "Taco salt." "Let's see what's in it?" Mr. Parks turned the jar and read from the back label. As he spoke, the ingredients appeared on a screen. "The ingredients are 'salt, dried red and green bell peppers, granulated sun-dried tomatoes, celery, parsley, cilantro, onion powder, cumin,... read more
