Statistics and Report-writing Discuss with your neighbour. (Don’t all start at number 1) 1. Why is it important for students to be able to write good statistical reports?

2. How well are your students doing at writing reports? Why might they not be doing as well as you would like them to? 3. What are you doing to help them develop their report-writing skills? 4. Why is it difficult for mathematics teachers to teach reportwriting?

Statistics and Report-writing 1. Why is it important for students to be able to write good statistical reports? •

You don’t realise whether you understand or not until you try to write it down. The process is important.



Better critics of other reports



Part of the literacy initiative



Useful skill for employment – report writing, and literacy generally



Required for marking!

Page 9

Statistics and Report-writing 2. How well are your students doing at writing reports? Why are they not doing as well as you would like them to? •

Writing too much – brain spill – 65 pages!



Repeating themselves



Not sure what is relevant so put everything in…



But leave out important aspects



Non-sentences



Poorly structured



Not enough linkage to the context …or…



Too much context and not enough analysis



Some are great – generally from social-science students

Page 10

Statistics and Report-writing 3. What are you doing to help them develop their report-writing skills? •

Guidelines



Feedback



Practice •

Homework



In class

Page 11

Statistics and Report-writing 4. Why is it difficult for mathematics teachers to teach reportwriting? •

Not used to teaching or assessing written English



May feel uncomfortable and lacking in skills



Few resources available to help



May be unconvinced of the necessity of the task



The students themselves are not happy with writing

Activity Time series output from iNZight.  Monthly retail sales in $m in the USA of different categories.  Raw data.  From http://www.economagic.com/cenret.htm

Your task  Find something interesting in the graphs.  Write down a good sentence and a not so good sentence about it.  Share your sentences with your neighbour(s).

 Choose your best and worst sentences and write in big letters on paper to show the class.

Time series output

Show us what you wrote! Short idea sentence to complete detailed sentence: Books peak in August. This is a good idea sentence! Books = the retail sales of books in the USA Peak in August = are greater in August than in any other month. Convert to a sentence: The retail sales of books in the USA are greater in August than in any other month of the year. Quantify: On average the sales in August are approximately twice what they are in other months except for December and January. Hypothesise: This is probably because August is the beginning of the school year in the USA, and people are buying textbooks.

Teaching strategies The report should not be the first thing they write Literacy is part of the statistics curriculum •

Small exercises for homework, peer review •

good feedback is necessary – descriptive rather than evaluative.



Checklists so they can see if the ideas are communicated well.



Warm-up sentences at the start of class



Write ALL the time while doing the analysis – clarifies thinking



“Fill in the gaps” activities give structure •

Make your own from a report. Remove words. (Cloze exercise)



On-line activities (NZStats 3 from Statistics Learning Centre)



Give examples and formats – writing guides



Page limits in assessments (self-defence for teachers)

Page 16

Writing Guides Teach principles as well as guiding assignment All four internal standards:  Time Series – Like a business report  Bivariate – Scientific

 Inference – Includes explaining the ideas of bootstrapping and confidence intervals  Experimental Design – Description of the whole process so that it could be replicated

Feel free to copy and use our writing guides, but leave the branding on them. There are exercises to go with them on the StatsLC.com site.

More ideas (if room in brain) Think about the role of context in a mathematics problem. Now think about the role of context in a statistical investigation. How are they different? Where do the three external standards fit? 3.12

How do we teach students to make sense of questions?

Collaboration Request I would be keen to work with a teacher on the literacy aspects of the statistics curriculum. I provide – sounding board, ideas, some classroom help You provide – some time, students to play with

NOT a big formal research project. Just trying things out. Talk to me later if you are interested.

How to use NZ Stat 3 on-line resources

Page 21

Homework •

Teachers assign a certain activity or quiz for homework.



Students can show their completion by printing out the results. (We provide weekly reports)

Classroom enrichment •

Use the activities in class time to complement other work.



“Flipped” classroom - see my blog on this

Review •

The exercises in NZ Stats 3 can be used repeatedly.



Large database so students get a different test each time.



Students can also track their own progress.



Good for Scholarship as includes all standards.

Help with assignments •

NZ Stats provides guidelines and practice in report-writing

Replace the textbook/homework book •

Cheaper and better! 
