Getting fired up about the start of term.

Yes, another PD session today . The time left for planning was great and I am feeling ready to start the new term. The work done at the end of last term has made this easier than expected thus far. Our TIC provided input on the course and directed worthwhile changes. Programmes and daily plans are written for the three year 10 streams my yr 11 1B/C classes, 3A/B MAT, 3A/B MAS and yr 12 Modelling with Mathematics. Yay!

We're all pretty keen to get started and even the most cynical of us are looking forward to what the year can bring without last year's threats of industrial action. Let's get on with the job of teaching.

The PD material was of dubious standard with a part time presenter condensing a week long course into 1.5 hrs to a group of 60 teachers from different learning areas. The topic of course was literacy, which meant another rehash of primary strategies, collaborative learning and.. you guessed it.. graphical organisers.

We were asked 'how we knew that students were engaged?' with a range of answers from 'if a student is looking at you (culturally inappropriate in many cases)' to 'actively answering questions (disposition/culturally inappropriate)'. No answer was given by the presenter (I think her answer was discredited before she had a chance to supply it). Doodling notes on the page was deemed a valid method of note taking. We again were informed that the 2 squillion genre's were a necessary part of learning and teaching.. a focus on breadth of learning over depth again. The change in emphasis from version 1 to version 2 of First Steps is a shame as the original First steps had focus and is still a valuable teaching tool as it gave students a foundation to learn other genres. Despite being a Maths teacher I own copies of both the first and second editions of First Steps.

The presenter put us in a lineup and instructed us to stand from engaged to not engaged. She then asked us 'Did we feel engaged by PD opportunities? and to position ourselves accordingly in the lineup. I stayed where I was which was on the disengaged side. As I had been critical of earlier answers (and was sitting under the presenters nose) she asked me why I felt disengaged from PD sessions. I said that I rarely encountered worthwhile PD (to which I embarassingly received a clap from staff). Yep.. that's me.. survival skills of a bunny on a freeway.

More seriously I would add to that PD's are rarely well prepared as they inadequately take into account prior learning (no more bloody graphical organisers!), show little awareness of the requirements of staff (we had staff from every learning area), have no follow up or action points (this may be more of a management issue), take too long to tell too little and generally are just not good value for money. She rightly guessed I was a maths teacher as I was critically evaluating the value of PD sessions.

On just the value for money point.. 1.5hrs x 60 people at an average of $70,000 per year conservatively cost the school $3,000 in lost wages. That's a projector installed for each of the teachers in Maths which would benefit 150 students every year or a new set of text books for a classroom. It has an opportunity cost of our students having a more cohesive programme that could have been developed. I would be interested to know how many graphic organisers are actually used in classes or how many teachers use the text supplied.

I don't accept that we should be grateful for any PD given and accept mediocre presentations. If we waste 90 man hours of training time, it is a criminal waste. We cannot stay professionals and not continue to learn our craft. Without good PD opportunities we cannot grow at our optimum rate.

I took away one point from the PD, an interesting example on the use of questions to promote discussion on a subject. It was ok but explicit teaching would have imparted the same knowledge (drink water if in the desert) in 1 minute rather than through a round of discussion. I can see how it could be useful and is another tool to use in the kit bag. It also explains why a number of my alternate lessons work..

The materials presented by the principal were great in that they allowed teachers a chance to vent concerns in a healthy environment. In another session it was interesting to hear that 360° reviews were contemplated and rejected (where teachers review performance of management and vice-versa). It's difficult to see the benefit of inexperienced management staff reviewing inexperienced staff. It's all a bit silly really when experienced staff exist to perform the teaching review within the school.

It was raised that we needed to communicate better with like schools and embrace some of their successful strategies. This is a great idea - unfortunately one rarely possible. It would be good to see long term strategies that lead to teachers on loan to adjacent schools for terms, semesters or for the year, further developing our abilities and bringing back learning to our schools.

It was nice to hear that many teachers thought our mathematics summer school was a worthwhile first attempt. It will be interesting to hear the anonymized results when they are handed to admin by students on the first day back. These trailblazing year 11 3A MAS and MAT students are the bleeding edge of our new maths students and for them to succeed would be great for them and the school.

Only time will tell.

Understanding reports in WA

I am often asked to interpret reports of friends children and explain to parents what the report really means. I am no expert on writing primary reports but I am critical of the lack of transparency in school documents and the degree of technical literacy required to understand them.

Reports are one of those things that have been bastardised by bureaucracy and politics. To be honest their usefulness is limited in their current form unless you are a teacher or bureaucrat. Even as a teacher, the variance of grading between one teacher and the next is too great making the data unreliable and thus is rarely referred to. Here are two cases that recently presented themselves.

Scenario A
Student is in year 7, has been given an excellent report. He has a level three in Maths and English and is finding school boring and too easy.

Q: Is my student doing ok?
A: Probably not. If they are level 3 and finding school easy then they are not being extended enough. Asked student to record what they did today in paragraph form (not dot points). Spelling accuracy was limited. Student was writing without an understanding of conjunctions, limited punctuation and was writing very slowly. Student could not recall last book longer than 10 pages read. Student could not recite 4 or six times tables. Student had limited understanding of order of operations.
Remedy: Indicated that parent needed to take greater interest in performance of student. Suggested student complete homework at kitchen table each night with parent assisting and providing additional examples to complete. Indicated a few books that the student may like and indicated that parents reading with them would be a good idea. Suggested methodology for learning tables and order of operations.

Level 3 is the minimum level a student should be getting in year 7. You would expect students to be completing a variety of level 4 tasks in year 7. Sadly many teachers are only teaching level 3 material. This is very evident when talking to primary teachers at PD through their lack of understanding of level 4 tasks in mathematics.

Scenario B
Student is in year 4. He is the top of their class in mathematics and performed well in NAPLAN testing. He has been given a B. The student is distressed as they expected an A.

Q:Huh? How can this be?
A:Back in the day when we were students, results for a class were scaled to a normal distribution - each class had a few A's, a few more B's, lots of C's, a few D's and a student or two earmarked for being held back. Sadly this is no longer the case. If a teacher does not teach the 'A' material (for whatever reason defined by that abomination smartie chart), an A will not be given, the same goes for B's, C's, D's & E's. In this case this is what has happened. NAPLAN testing at this level is more IQ testing than progress testing which is why this result was consistent with student and parent expectations.
Remedy: I supplied printed copies of progress maps and pointers for mathematics and links to sample items for the next NAPLAN test. Suggested parents consider looking at level of student and work at assisting student understand material at the next level.

It may sound ok to define 'A' material and provide an 'A' consistent with students across the state until you consider that in some low socioeconomic schools if grading was done consistently with curriculum framework directives, no student would get higher than a C for the first years of schools whilst they caught up to their contemporaries in more affluent schools. Even gifted students (but lacking environmental support) get discouraged as they try to overcome their lack of support at home and get C's despite making large jumps in knowledge and applying themselves. Although the idea of A-E grading was good, the application was poor. For low ability students in lower classes - they may never get higher than a D despite a great work ethic and working at a level consistent with their peers.



The solution? Provide normalised results for each class on reports (allowing students to get grades in relation to their peers) and use NAPLAN tests to show progress in relation to other schools with expected ranges for university and TAFE entry. Duh!

(Addendum 30/1/2008: It is interesting to note that the West had an informative article on just this topic today.. details of the article can be found here (half way down the page) by Bethany Hiatt titled "Parents need lessons on the grading system". Yes I am being positive about a media article - must be the optimism and endorphin spike associated with the start of a new year.)

Trigonometry and CAS calculator I

During exams last year we noticed that those who had CAS calculators were not using them for Trigonometry problems. During summer school we sought to rectify this. To start with we looked at properties of triangles.

Students stated that the calculator would give no solution when solutions existed. This sounded doubtful but I had a good idea where they were going wrong.

I started with the following. Take three lines, 4cm, 2cm, 1cm. Now obviously this can't make a triangle. Right?




No matter how we change the angles at A & B they cannot form a triangle. This was to inform students that a no solution result in their calculator had meaning.

So now we had a look at a problem that they were having difficulty with.

In their work pads they had written A=x, a=5cm, B=72°, b=72 and labelled the triangle correctly. So far so good.

They could tell it was a sine rule problem but had difficulty entering it into the calculator. Where did the sin, cos, tan buttons go from the calculator?

The first thing to do is find the sine function. Open the soft keyboard, select the mth tab and press the Trig button at the bottom of the keyboard.



Next enter the sine equation with the substituted values. They needed the fraction template inside the soft keyboard under 2D






Hitting execute at this point gives no solution. Huh?

Well.. we still have to solve for x. So highlight the equation and go to the interactive menu (in the menu bar at the top of the work pane), select Advanced and then solve. The Equation should be there and the variable listed should be x.



After a rather long wait a huge expression appeared with a strange looking answer.

I'll rekey it here as the whole answer does not appear on the work pane on the calculator.

{x=360.00.constn(1)+137.209, x=360.00.constn(2)+42.791}

The answers are the two bits in red (at this point we had a bit of a chat about the ambiguous case with the sine rule). To get to the answer you have to navigate with the style and the left/right arrows at the edges of the equation.



So the answer is x=137° or x=43° (0 d.p.)

We then drew these triangles to give students a better understanding of the ambiguous case.

In the next example we'll look at the perils of rounding and go back to the case above with the impossible triangle.

Solving Simultaneous Equations using the Classpad 330

There are a number of ways of finding where two lines intersect. Let's solve this example.

"Where do the equations y=x and y=-2x+3 intersect?"

One way to find the solution is to solve the two equations algebraically using simultaneous equations.

First open and clear the main work pane.



Press the blue Keyboard button and bring up the soft keyboard. Select the 2D tab.

You should be able to see a button with a bracket and two small boxes (circled below in red). Press it.

You should see the simultaneous equation template in the main pane.
(Update 1/6/2010: Press it twice to add a third equation line!)

Click on the first box and type y=x

Click on the box below it and type y=-2x+3

In the third box to the right of the vertical line type x,y (the variables we wish to solve).

Hit the exe button.

The answer (x=1, y=1) should appear.

Classpad 330 and Normal Distribution

Normal distribution problems can be done quite simply on the Classpad 330, but the method seems a little weird.. perhaps I haven't found a menu yet, or completed an update.. but here's how I did it for the following problem.

"A packet of mince contains 500g of mince. Suppose the actual weight (x) of
these packets is normally distributed with a mean of 512 grams and a standard
deviation of 8 grams. What is the probability of picking a packet between 504
and 520g?"

Firstly open the main window and add the list editor from the toolbar.

Opening the list editor should make the Calc menu appear in the menubar at the top of the window.

Select Calc->Distribution. This will make a popup appear with some options

The Type dropdown needs to say Distribution.

The second dropdown should say Normal CD. After that is selected tap Next. A new dialog box will appear.

For our problem the lower bound is 504, the upper bound is 520, the standard deviation is 8 and the mean is 512. Tap Next when this has been entered. The answer will appear with a probability of 0.683

Tap the graph icon in the toolbar to view the distribution.

Viola!

Middle school & end of year reflection

After a year of trying to establish rapport with middle school I think the obvious is as follows:
Without teaching upper school classes and being involved with NCOS, middle school teachers have disconnected from upper school requirements through no fault of their own.

Added to the traditional "it's an issue at primary level - but we have five years to rectify it" we also now have "it's an issue with middle school, how can we possibly fix it in two years".

Students wrapped in cotton wool, unable to connect success with working hard find senior school difficult.

Assessment changes and alteration to pedagogical methodology in middle school has reduced the rigor required for TEE subjects especially in those with little discipline at home.

Without a detailed syllabus, critical topics can be deferred to later years causing irreparable damage.

Responsibility for subject performance should be left in the hands of those that understand the subject area.

Graduation should not be automatic. Pastoral needs of the individual should not be placed above the academic needs of the student and group as a whole.

Students can be entertained and placed with friends to stay in school but when once the demands of TEE level education arrives, it gives students too little time to adjust to the requirements of real study. The adjustment needs to occur in year nine - especially for the gifted kids.

General observations from 2008:
Streaming in mathematics is required where more than four levels exist across a cohort.

Intervention time is limited to less than 1 minute per student in homogeneous classes greater than thirty and puts teachers at risk with the current defer intervention actions BMIS discipline policy. Intervention time is greatly increased in a streamed class as peer assistance, direct instruction and modelled lessons become more effective.

Collaborative lessons can work when consequences for non-performance are correctly administered (peer pressure is a fantastic tool in this case).

The most reward comes from success with students with the least demonstrated ability.

Any student (without a learning difficulty) can learn any topic given an adequate amount of time (Kevin Casey).

Male students are not getting the results in mathematics in line with their ability levels.

It is possible to make a difference. Bring on 2009.

Intuitive Teachers

I wonder if there is a connection between those that deal with a lot of people and their ability to be intuitive towards their needs. As teachers we need to be able to "read" students as many times their articulated response may not reflect their needs.

I've found that since teaching it is easier to read what people mean compared to what they say. Is this a common finding? Do occupations that deal with a lot of people on an ongoing basis develop the same ability? Does frequency of interaction hone the ability further? Is this a trait we should be looking for in new teachers in the same way we look for bedside manner in doctors?

Making schools a part of the social system

Many attribute social behaviours to treatment within schools.

Children under the age of 18 are arbitrarily required to attend school or seek gainful employment. Yet many of the children in our justice system are no longer attending school or seeking gainful employment.

Similarly, many children in schools are not students, but young adults actively being impediments to the learning of other students. They have little or no interest in schooling and have no interest in seeking gainful employment.

If students have no interest in schooling or are not in gainful employment I suggest that we strip them of their rights as children and call them adults... any illegal activities get tried as adults, protections given to children are removed and sentences roll into the adult system as they turn age. After all not in school, not acting like a child, demanding adult responsibility and treatment - grant their wish.

Similarly if a child is not contributing in school, not valuing their education, being an impediment to the learning of others (with no feasible solution available to get the child performing as a student) .. whoosh - out they go either into an alternate programme off campus or into the real world as an adult and lose their privileges as a child.

With one proviso - any government payments for children are instantly stripped if they stop attending school and adult payments for these children are not available until they turn 21 if school is not finished (a very simple process that could be completely handled electronically). Exceptions would be handled on a case by case basis with very strict criteria after testing for learning disabilities and available environmental supports.

Whoa! I hear you say.. that's a bit radical... but nobody values what is given on a plate - only when there is a risk of loss is it valued. For schools to be a part of the social system, it needs to be recognised that schools cannot be held account for all social ills, they can though be a filter for recognising them and helping the borderline cases back into the mainstream. Stuffing extreme cases into an already taxed system and hoping all will be ok runs the risk of dragging many more real students down with it. Schools should be centres of learning filled with students and families that value education... not a young adult minding service.
