education is one of those things that people will pin you to the wall to talk about. At least those that have wrestling training do.

But what I wanted to ask was: In being a teacher, what should my tactics be? Strategy? how should my examples flow? WHAT DO I DO?
In a little bit I'll restate my questions, but I hope for some answers now so I can construct those real questions.

    Where in Washington are you? Close enough to get down to Portland?

    What do you do? First and I hate giving this advice, during your credential program sagely nod your head and pretend to think that what they tell you is worth anything (some of it truely is useful, but not a lot). When you are done, forget what you where taught. Educational research focuses on elementary students and projects the results through high school - no one (well very few) does studies that track students and how they respond to a variety of teaching methods from elementary school through high school. A common result of this is that what appears to work in elementary school often turns out to be a real disaster for the students later. A good example of this is the heavy use of calculators in school, often starting at the 3rd grade. Personal experience with several hundred students tells me that students who depend on a calculator rarely understand basic arthametic which greatly hinders their ability to learn algebra.

    What makes a good teacher?
    - Someone who knows their subject, but often not an expert. Experts tend to forget where people have problems learning a subject.
    - Someone who is strict but fair.
    - Someone who is engaging.
    - Someone who enjoys teaching.
    - Someone who is adaptable and pays attention to their students.
    - Someone who is willing to their lesson plan sucked.
    - Someone who can clearly present ideas, with examples. A common failling in education today is the idea that the students should figure everything out. This is especially true in mathematics. It has taken us thousands of years to get where we are, no matter how bright the students they will smart enough to figure everything they need to know or even most of it.

    The real answer to your questions, comes down to what works for you (and your students). Start with copying teaching styles that you found effective.

      I'll agree with that advice. As a teacher with a BS and PhD in chemistry and an MA in education, I can unquestionably say that 99% of what I learned in my education classes is garbage. The one class I found useful/helpful was tests and measurements - we learned to write test questions and grading rubrics, though I'd say it was more helpful in making me a better test taker. I can nail almost any multiple choice question whether I know the subject matter or not, but I digress...

      To be a good teacher, you should be a good communicator with an infinite supply of patience. Subject matter knowledge is important, but it doesn't get you anywhere if you can't explain the information to someone else (IMO, practicing can make you a better communicator, but honestly, it's either a skill you have or one you don't). Fairness is a must and very hard to achieve, but there are ways to work on it. Engaging and/or entertaining can be good, but some of the best teachers I've had were dry, dry, dry, but they were excellent communicators and could explain the same thing ten dozen different ways until everyone in class understood. Be honest, especially when a student asks a question you can't answer or don't remember. Kids will (generally) respect you more if you can admit your shortcomings. I've found that a good answer to such a question is, "I don't know the answer. Why don't we both try to find out and compare our findings tomorrow." The other necessary attribute is flexibility. I'd say if you're a good communicator, with a heap of patience and flexibility, you're about 75% there.

        Beware of educational fashions, unlike clothing fashions, they take ten years to go away and are almost always bad.

        As unfashionable as it is, drills and practice will provide the experience for the students to develop an understanding of the material (we're talking pre-90's teaching styles here). Only in education are drills and practice considered bad (... because it is boring) - in every other aspect of our lives it is essential. Ever hear of a couch who told his players the game plan then considered them ready to play without practicing it? Me neither.

        Have high standards for your students. You will hear a lot about high standards but won't see much of them. In fact, you will hear a lot of denials that the circulum hasn't been dumded down, don't believe them. The last I heard, the freshamn drop out rate in the UC system was running near 50% including at Riverside and Irvine where the average entering GPA was ~4.5 (+1 for honors courses) - students aren't being prepared. End grade inflation.

        IMO "meets all expectations," i.e. 100% of the standard, should be a B or B+ grade. Leave room for students to exceed expectations, that is what A's are for and they should be hard to get. BTW C = average or meets minimum expectations, this is the grade most students should get.

        If you give extra credit, make it hard. Allow all students to try it, those that are getting low grades (< B) shouldn't be able to get it right unless they are just blowing of the regualar assignments out of boredom (it happens a lot). I made my extra credit harder than my tests and told them so - forced the poorer students to focus on the regular assignments and gave the high achievers a challenge.

          Well this is all close to what Ive thought. I wasnt sure about the rigourous path to education since I was very aware of the grade inflation thing, and Ive seen what happens when a teacher is a firm believer in that a subject worth learning is worth learnng well. The teachers health went down due to stress, and the school askd her to not come back. But I digress.
          In highschool I wonder how much of the curriculum should be in learning about the math, and the subject, and how much of it should be in teaching the students in how to LEARN the subject. So if Im talking about disassociation I should show them several ways t think about it, to show how to find out what the values are for any compound they w\ant(via the CRC? Via web?) and show them how to estimate what a compund show do under certain circumstances. I am under the opinion that highschool is where we learn to think and be creative, and how to learn and visualize, and college is where we learn the hard crunchy bits.
          I would agree that being able to explain subjects in seveal fashions is important, My wife is annoyed sometimes at me for continuing to explain something another way, after she had already got it.
          I would agree that drill is useful. I think the caution should lay in making it effective drill. Sending them home with 20 problems from the text is maybe not as effective as 5 problems in the beginning of class every day. Repeating a drill throughout the qtr/sem would be a good way of firming it up.
          Patience is a virtue. I have it. It has been a sore point, and a point of exasperation when people percive my level of willing to wait. I have heard them decry me as "zenner than thou" or as being stupid to wait for ten years for something I wanted. But thats neither here nor there.
          I want to be a teacher, I have patience, I have the ability to explain things multiple ways, and I know I need lots of tactics.
          So, about tactics. Ive noticed most chemistry being the examination of where do the electrons flow to? and where do they come from. Acid base rxns are big for that reason. henderson hasselbalch is big in quantitative analysis, in biochemistry, and in the first qtr ochem, and in gen chem.. Ive noticed that there are many ways to qualitatively show acid base rxns, and was wondering if there were any examples, experiments, graphics, or key phrases you would use to explain acid base rxns, or the like.

            "Sending them home with 20 problems from the text is maybe not as effective as 5 problems in the beginning of class every day." Both are useful, it just depends on your teaching style. Personally, I found it very useful to have the students do a lot of problems but I was often working with math students who had a poor understanding of the basics. As students' understanding increases the less repeation will be needed to a point.

            "In highschool I wonder how much of the curriculum should be in learning about the math, and the subject, and how much of it should be in teaching the students in how to LEARN the subject."

            In terms of teaching students how to learn, well that is a very individualistic thing, offer suggestions. On this point, in the end, the students will either figure out what works for them or they won't and there is little you can do about it either way.

            In terms of tactics, you have to figure out what works for you. I would suggest that you limit yourself to three different ways of explaining things unless you are asked for more. The students who got it on the first or second will wait for through a third but will often tune EVERYTHING out after that.

            "I wasnt sure about the rigourous path to education since I was very aware of the grade inflation thing, and Ive seen what happens when a teacher is a firm believer in that a subject worth learning is worth learnng well. The teachers health went down due to stress, and the school askd her to not come back." Being a good teacher is very hard work with very long hours at first. Besides poor health, the teacher may have been not asked back because she made the other teachers look bad... Gotta love politics.

              I think I must be naive, because I really have a hard time believing it could be politics. That just seems so BASE.
              At the same time I know nothing of what teachers do in universities, so who knows. I have been told to expect quite a lot of bureaucracy, and politics when I start teaching, so I have learned to keep my awareness of it, but I don't even know what form it will take. I'm guessing I'll find out more about that kind of stuff when I start taking education classes. At this point I'm enjoying taking my science classes. I remember the one research paper Ive done about education, which I though I did well on. It was about grading. I remember being a little proud of my self for having read about 100 journal articles to form some opinion on grading practices in highschool science. Then a teacher I met from oregon commented that that really isnt much. and there is a whole lot more that is done before people write a paper. So I guess its nice to know that people do research, and that I can continue to learn and study. I just hope I keep learning.
              I like teaching. I think IM good at it. I think I chose well. But I do get a little wary of the furture when I think about grading practices, discipline, homework, testing, and all those other aspects of teaching which is more than just getting across to one kid, To one young adult. When I have paperwork to deal with as well. I get a little scared. I know everything will turn out all right, but Id still like to know whats going to happen, and to talk about those things before hand so I can start prepping for them. Can I prep for them?

                Actually no, unless you take education courses about education adminstration, and even then it is highly unlikely, the bureaucracy and politics of teaching aren't covered in the classroom. My best suggestion is to read both "How to win friends and influence people" by Dale Carniggie (sp) and "The prince" by Machiavelli (which does not diserve the bad rap it gets).

                I don't know how much statistics (not probability theory, statistics) you know so my next comments may not make much sense. Be very wary of educational research, even when it pretains to teaching science. A lot of educational research is conducted on small groups, often less than 20, and for short periods of time. Because of that it is only suggestively qualitative. Twenty people sounds like a lot but in reality is tiny once one starts to think about all the variables each person represents. For multivariate statistics the general rule is that one needs at least three examples of each degree of freedom (variable) to get a reliable result. Let's consider some of the factors that could effect an educational study: student gender, student age or grade level, student ethnicity, student economic background, educational background of the student's parents. I just listed 5 degrees of freedom but let's only consider one grade level (which means the study's results may not apply to different grade levels), so we effectly have 4 degrees of freedom. That means we need 3 boy and 3 girls (6) of each ethnicity (say black, white, hispanic and east asian = 4) and of each economic background (say poor, middle class and rich = 3) and of each parent's educational level (say high school or less, BA and grduate school = 3) for a total of 6*4*3*3 = 216 students. There are some methods that can reduce that number a bit but one can't get it down to the typical numbers used in educational research. What is worse is that we still aren't considering the effect of the teachers and teaching methods on the studies. I hope I have given you a feeling of one of the issues that effects the usefulness of educational research.

                " But I do get a little wary of the furture when I think about grading practices, discipline, homework, testing, and all those other aspects of teaching which is more than just getting across to one kid, To one young adult." The sane don't teach but then again the sane are boring.

                "When I have paperwork to deal with as well. I get a little scared. " The paperwork is demanding, good TA's help alot but you'll just have to find a strategy that works for you. Eventually I had a policy of not giving a grade to anything that I didn't correct myself, meaning I only graded reports and tests but not homework. That was tricky because I told the students what I was doing, to make that work I had to convience the students that the homework was the practice for the tests much like pro-sports players are paid to practice for the game (be honest with yourself, you know the pro-players would play games even if they weren't paid but going to practice is a different story) - I made it work but I don't suggest that a new teacher try it.

                "Can I prep for them? " You are doing just fine.
