Top 10 Least Effective Teaching Methods

!±8± Top 10 Least Effective Teaching Methods

Teaching is tough enough. However, if you really want to make it hard on yourself and turn off your students, try one of these.

#10. Give pop quizzes...I firmly believe that unannounced "pop" quizzes are a bad evaluation tool and do more harm than good. It's nothing more than a game of "gotchya" with the students. Math, in particular, causes a lot of anxiety in students. There's no better way to redline the anxiety meter than to walk in and give an unannounced quiz. However, I did have a policy that anything we did in class or out was subject to being collected and graded, which I did at least once a week. This included homework, warm up exercises and class notes. There's nothing wrong with keeping the students on their toes, but unannounced quizzes aren't a good tool for that.

#9. Use homework for punishment...When I went to school many moons ago, this was very common and unbelievably it still goes on today. You can't get any more clueless than this. If you're having problems in the classroom, the last thing you want to do is assign a ton of homework. First, it doesn't correct the basic problem, which is probably discipline or control related. It antagonizes families and sets up a power struggle with the students that you can't win. What if they don't do it? Then what? Suppose they do it? Now you've got hundreds of problems to grade, like you don't have enough to do already.

#8. Allow students to start slamming books and getting ready to leave while you're still teaching...This falls under the classroom control category but is so common and disruptive, I mention it separately. When books start slamming, it spreads through the room like a virus and everybody immediately shuts down. If you don't address it, you surrender your classroom and lose valuable teaching time. I made it very clear to the students that I dismiss them, not the clock. Learning and practicing dismissal procedures should be part of the early year routine. I called mine the two minute drill. When finished, the classroom had to be clean, desks lined up and students sitting quietly with me sitting on the Cone of Silence. I'd offer a few quick comments to end the day on a positive note and off they would go. Make dismissal part of the learning process and not a free-for-all where the teacher is a bystander.

#7. Allow calculators before the students show they can do basic math without them...Calculators are great for teaching intermediate to advanced math concepts. Nobody wants to calculate powers or roots by hand. However, students in general are way too dependent on calculators for even simple arithmetic problems. Calculators can actually make math problems more difficult. It adds steps and every step is a chance to make a mistake. Your key punching has to be perfect. Since you can't see a calculator's work, you have to use estimation to evaluate the answer. If it doesn't check, the only alternative is to do it over. Nevertheless, students, parents and even administrators think memorizing basic math facts and practicing with pencil and paper is unnecessary since we have calculators. I couldn't disagree more and aggressively drilled basic arithmetic all year in all grades. In fact, to use a calculator in class, the students had to pass their CQ. In Naval aviation, that stands for Carrier Quals. In my math class, it stood for Calculator Quals. It was a short written exercise with several types of problems. Students had to score 80% or better to "qual".

#6. Put students in groups too soon...I had a practicum student in my classroom for a week one time. After he had observed for several days, I gave him a chance to teach a class. I don't remember what it was on and it doesn't really matter because it was an unmitigated disaster. He put the students in groups of four, handed out manipulatives they had never seen before and tried to take them through an exercise for which they had no background or preparation. He did it because that's what they teach education majors in college. I got the indoctrination too. Group work is the Holy Grail of teaching. It's fun. It motivates. It levels the playing field. It's inclusive. It differentiates. It's the rising tide that lifts all boats. Well maybe, but there's a catch. Effective group work requires a classroom dynamic that will support it. For starters, you have to know the name and temperament of all your students. The teacher has to have absolute control and well established routines. The students need to exercise self-control and recognize limits. It takes weeks to establish that environment and some classes never get there. One of my very savvy college instructors told me "Don't even think about group work until Halloween. It takes that long to get them ready." She was right.

#5. Waste time...The typical school year is 180 days. If you waste two minutes a day every day, that's six hours of instruction lost over the course of the year in just that class. That's over a week. Now multiply that times the number of classes you teach. I've seen rooms where they are still trying to get rolling five or even ten minutes after the start of class. The lost time adds up quickly to a staggering number but because it happens in little chunks over time, nobody notices it much. Now granted you can't be teaching math from bell to bell. There are transitions, administrative tasks and routine housekeeping that need to be done. The goal should be to fill every possible second with the teacher's ideas, plans and activities. This has implications for classroom management and discipline. Keep the students too busy to conjure up anything.

#4. Use others to correct your tests...This is a real pet peeve of mine. Grading papers is a pain in the neck, but a very necessary one. One of the few times you have the undivided attention of all students is when you hand back their tests. Thorough grading and commenting gives you a picture of both individual students and the entire class. It can also give valuable feedback on your teaching. So why would you sacrifice one of your most powerful teaching moments by having someone else grade them? Granted, it's easier, but it robs us of the most important tool we have for evaluating student understanding and teaching effectiveness. I saw it all the time. Parent volunteers and para-professionals sitting in the hallway with answer keys robotically going down the list and grading papers. Do they know why the student missed the problem? Was it an arithmetic error at the end or an algorithm error from the start? How many others made the same mistake? Have the students followed your test instructions? How about partial credit? The ghost graders don't know. If you give it, you grade it. Let the volunteers clean the boards.

#3. Give students the power to disrupt your class...You're trying to get things rolling and then it starts albeit innocently enough. Can I sharpen my pencil? Go to the bathroom? Can I go to my locker? Can you sign this? What are we doing tomorrow? Or a student walks up to you right in the middle of class and tells you "Tomorrow's my birthday". We're teachers. We love kids and have kids of our own. We want to be approachable. We want to help. We want to answer student questions. But by acquiescing to these simple requests, you are surrendering control of your classroom. Students figure out real quick that they can dictate the pace and agenda in the classroom by simply interrupting with something simple but completely unrelated to the task at hand. The answer is routines - explained, practiced, rehearsed and enforced. When I first started teaching, I had 6th grade math classes. Sixth grade was the first time they changed rooms and had different teachers for different subjects. The first habit I had to correct in them was this business of swarming around the teacher, which they had been doing for five years. My standard line was "This is not a bee hive". There's a way to ask questions and when you do it properly, I will be happy to help you. The first couple times I did that, kids started crying. They went home and said I was mean. Then the phone calls started, but within a week, we were settled in.

#2. Lose your sense of humor...I believe this is the most important trait for a successful teacher. Humor is a powerful weapon in dealing with crisis and chaos. It defuses bad situations and gives people confidence in you. That doesn't mean you're a stand up comedian or the life of the party. Telling jokes is a bad idea, but poking fun at yourself makes you human and more approachable. You have to be able to laugh and not dwell on the tribulations you face in the classroom. Every teacher is different and you should be yourself. Just don't take yourself too seriously.

#1. Take it personally...My favorite line in the Godfather is "It's nothing personal. It's just business." That line gave me perspective through some tough times. When students openly defy, curse or assault you...When parents question your competence and integrity...When administrators embrace another buzzword initiative like "spiraling"...There is a natural tendency to want to retaliate in kind. You have to be able to compartmentalize it. Never lose sight of the fact that it's part of the job and deal with it as a detached professional. If you personalize it, you start to get dumb and reckless. Frequently, that leads to saying and doing things you'll regret later, like sending an email blast to a parent or calling a student an ass. Don't ruin your day, your health and your career over slights real or imagined. It's just business.

I sincerely hope you never need to use any of these but trust you enjoyed the read and maybe learned a few things.

The History of Calculators

!±8± The History of Calculators

There was a time in history when simple arithmetic was compulsory in school. As technology emerged new discoveries quickly transformed the way we used traditional methods. One of these great inventions was the calculator. Modern calculators differ from old counting instruments. Numerical devices such as the abaci and comptometers were a manual process that was full of errors and quite tedious. Conversely modern calculators are digital or solar powered and don't require much manual labor. They are very inexpensive and come in many sizes and models. Listed below are seven lucky facts about calculators you should know:

In Education
1. There was plenty resistance to using calculators in school because it was thought that it would take away from their basic arithmetic skills.
2. Some scientific research indicates that insufficient guidance in the use of calculators can hold back mathematical thinking that pupils learn. On the flip side, others dispute that mathematical devices can cause fundamental mathematical skills to weaken or that such use can prevent learning of key mathematical concepts.

History: The Early Days
3. The first type of calculating instrument that was implanted was the Abacus. They were made out of a square shaped wooden piece with beads sliding up and down on wires. The Abacus is still used by merchants and fishermen in Africa and Asia.
4. The first recorded analog computer was in 150 BC. It was called the Antikythera mechanism and the astrolabe. These computation devices were made in Greece.

17th to 19th century
5. Wilhelm Schickard a German mathematician made the first digital calculator in 1623. He is dubbed the father of the computing era. His design used techniques that a clock used so addition devices were originally called computing clocks.
6. These gadgets were later improved upon by Charles Babbage (rhymes with cabbage) when he invented the mechanical calculator. It was called the difference engine because it could manipulate seven numbers of thirty-one.

Present
7. In the early eighties computing gadgets were a luxury item costing about two weeks pay. Prices dropped as cost of construction material for these devices became less expensive and accessible.
Today it is difficult for manufacturers to make a good profit of selling calculators solely. Consequently companies have competed to find unique strategies to sell computing devices. You can now purchase them as a dual items on mouse pads, pens, rulers and almost anything you can think of.

Tips For Using A Graphing Calculator In A Statistics Class

!±8± Tips For Using A Graphing Calculator In A Statistics Class

When a student enrolls in a statistics class, a graphing calculator is going to be one of their most valuable tools. These calculators have many important functions that make it easy to solve very complicated problems. However, it is only helpful in statistics class if a student knows how to use it properly.

Before purchasing a graphing calculator, students must make sure they have chosen a model that is intended for use in a statistics class. In many cases, the packaging on the calculator will mention which classes the piece of equipment is best used. If a student cannot make a decision, they can always ask their teacher which model will be best for the course.

Just as there are people who can tutor students in math concepts, there are tutors who focus on helping students learn how to use their graphing calculators. Working with a tutor can often be more helpful than simply trying to understand the manual. Students should not underestimate how complicated their new calculator is and the work that will need to go into learning how to use it.

Once a student has learned how to use their new graphing calculator, it will still be important for them to practice using it. If they are unsure of the functions, it is a good idea to practice on problems that will not be graded for class. The more a student uses their calculator, the quicker they will get at solving complicated problems.

A graphing calculator can be the best thing that ever happened to a student in a statistics class, but it can also be the worst. Students must commit the time they need to learning how to use their new calculator to its fullest potential. Once they do, they will be thrilled with the speed at which they can complete their classwork.

The Top 6 Calculator Apps For the iPhone

!±8± The Top 6 Calculator Apps For the iPhone

Our recent article on the top 6 calculator apps for Android was a big hit, and since then we've been getting search inquiries about iOS. You asked for it, and we are delivering. We've searched out Apple's app store for our favorite 6 calculator apps for the iPhone and iPod touch. Since there was a wide disparity in cost of apps, we set the ground rule that we were searching for apps that cost less than . In fact, this list turned out to be our favorite 6 iPhone calculator apps for under .

#1 Graphing Calculator+ by xNeat.com

Graphing Calculator+ is our pick for the best all around iPhone calculator app. It greatest strength is that it does so many different things well. A switch button takes you easily between the calculators different modes. Those modes are graphing, scientific, handwriting, a polynomial calculator, and linear equations calculator. There's still room for improvement. In particular, we wish the scientific calculator had fractions, and that the grapher had trace. But the app is simple and powerful, and the fact that it automatically finds max, min, intercepts, and intersection points pretty much makes up for the lack of trace.

Pros: Handwriting support, graphing scientific, quadratic and cubic solver, systems of linear equations

Cons: Handwriting mode not always accurate, decimals only

Cost: .99

#2 Graphicus by Serafim Chekalkin

We are huge fans of Graphicus. If only every graphing calculator were this easy to use. No need to read the user manual here, just jump right in. Graphicus brings you almost all the information you could want about Cartesian, polar, and parametrics graphs in an incredibly elegant interface. Trace, extrema, inflection points, tangent lines are all readily available with a few taps of your finger. On the downside, there is no simple scientific calculator. It's also a minor bummer that there's no 3D in an app that's 100% focused on graphing, but there's only one app on this list that has 3D.

Pros: Offers everything graphical, intercepts, trace, inflection points, max/min, complete

Cons: Just a grapher

Cost: .99

#3 Symbolic Calculator by Janos Barkai

If you need a CAS for your iPhone, this is the app for you. For those who have used a TI-89, you'll feel right at home with with Symbolic Calculator. The focus of this app is it's computer algebra system, and the interface is pretty easy to use for those familiar with Texas Instrument's CAS calculators. If you're new to CAS's, just tap the question mark next to a given command, and an example will pop up demonstrating how to use the syntax appropriately. You can also use this app to graph, although it feels a little counter-intuitive until you get the hang of it, and the graphing features are simplistic compared to some of the other apps on this list.

Pros: For a CAS, simple to use, offers example input for each

Cons: Graphing could be nicer, mathprint only after inputting

Cost: $.99

#4 Graph It by Tezmo

Another excellent grapher is Graph It. This is also full featured grapher, which offers the ability to trace, find intercepts, and roots, as well as graph derivatives and integrals. It also offers a full scientific calculator with two-line display. The user interface is ok, but might take some getting used to for some users, particularly for the scientific calculator mode.

Pros: Full featured grapher, also a full scientific calculator

Cons: UI takes a little getting used to

Cost: $.99

#5 Quick graph by Columbiamug

For those in need of a 3D graphing app, Quick Graph is the way to go. There are other positives here too such as a strong user interface, simple to use polar coordinates,and a good 2D graphing interface. Screen caps are another built in feature. The real selling point, though, is the 3D, which is well rendered and even accepts cylindrical and spherical coordinates. It is possible to use this app as a scientific calculator, but the interface feels a little strange.

Pros: Polar and 3D, screen caps of graphs

Cons: No trace features, don't feel designed for non-graphing calculation

Cost: Free

#6 Powerone LE by Infinity Softworks

Not everyone is looking for a fancy grapher. For those looking for a more standard scientific calculator, Powerone LE fits the bill. It's got a very intuitive interface that you'll pick up right away. Powereone also features unit conversion and a currency converter that stays current to international currency exchange rates. Additionally, its got a simple statistics calculator that finds the mean of a series of numbers. It could be better if the scientific features used a two-line interface.

Pros: Easy to use, nice UI, currency/unit converter, stays current, simple statistical analysis

Cons: One line calculation, no graphing

Cost: Free with option to upgrade to more powerful version for .99
