Ms. LaRosa is a great teacher. She can answer almost any question that you have about any history topic and if she cannot, she will try her best to help you find the answer. Although she has a hearing aid(助听器., she does not let that prevent her from being a great teacher. She told the class about it on the first day and told us not to let it get in the way of our learning and not to treat her differently.

We all like her class, especially an activity which is called the station. Stations are when our tables of four or five become our groups and we go through four various activities, such as Ancient China, in which we need to put together a sentence and write it using ancient symbols. Each station needs about 40 minutes to complete.

Ms. LaRosa has a policy that not many teachers give a second thought to. That is writing in cursive (草书的.letters. She will provide you with various resources so that your cursive handwriting is the best that it can be. Ms. LaRosa always says that she has a reason for everything that she does. Recently we just understood her reason for supporting cursive handwriting. Cursive writing can force you to think in words but not in letters. Also it has been proven that people who write in cursive letters do better on tests.

Ms. LaRosa’s class gets to do various fun and exciting things. She also uses real examples from her own life, such as things that her daughter has done. Ms. LaRosa also has absolute trust in her students. She always leaves her purse on her desk.

Ms. LaRosa is a great person and a great teacher who is always there for you, and I feel like I can tell her anything.
