USDA鈥檚 National Agricultural Statistics Service (NASS) and the American Statistical Association (ASA) have developed a new Census at School Food Preference Survey lesson plan and activities for students in grades 5-8.聽 Building on the existing ASA Census at School program, the Food Preference Survey teaches statistical and agricultural literacy to children through聽聽in Mathematics, Language Arts, Nutrition, Social Studies, and Family Consumer Sciences.

鈥淚ncreasing statistical literacy in youth is an important way to develop the next generation of statisticians,鈥� said NASS Administrator Dr. Cynthia Clark.聽 鈥淭丑别 Census at School program is a way to make statistics fun and engaging for students, allowing them to compare information about themselves with that of other students in the United States and other countries.鈥�

Students complete an online survey and submit the data to a national database. Statistical methods and concepts are then used to compare class results with random samples from peers in the United States and other countries.聽 Students will learn about statistics, nutrition, and cultural differences; apply graphing, mathematics, and analysis skills to real-world examples; and justify their analysis of data.

罢丑别听, using three questions from the full Census questionnaire, asks students about their favorite food and beverages. The activities use the data to analyze survey results and discuss whether the results surprise the class; which foods are most popular; whether certain beverages are more popular with girls or boys; whether and how the cafeteria could use the data to plan events and meals; if there is a relationship between favorite foods and whether someone is a vegetarian; and much more. The Food Preference Survey focuses specifically on information that could be useful to agriculture-in-the-classroom teachers, as well as other teachers of the common core standards addressed.

This lesson plan was developed by the National Agricultural Statistics Service (NASS), the American Statistical Association (ASA), with guidance from the National Agriculture in the Classroom organization (). For more information about the Food Preference Survey please visit聽.

Accompanying today’s release of the 2013 data we have updated 91茄子’s data tools to have the same simple, clean look and feel that we introduced for the rest of the site late last year.

For data-viewer and table-maker the changes the user experiences are purely cosmetic. The way in which settings are chosen in random-sampler has changed and now provides some control of sample sizes from subpopulations.

All data tools now have a prominent “Help” button near the top of the page.

A story about Census at School will air during Afternoons with Jim Mora on Radio New Zealand National (101FM) today, Monday 22 July at 3.30pm, and a slightly longer version again during Our Changing World on Thursday 25 July.

Nichola Coe, Head of Maths at Kapiti College, is visited by Radio New Zealand to learn about 91茄子. Nichola opens with this beautifully worded thought:

“I think there is a song to be sung behind every graphical representation.”

Professor Chris Wild and Rachel Cunliffe are also talked to.

Listen to the story:

Three-quarters of students aged 6 to 12 say they did homework the night before they completed a nationwide survey 鈥� and on average, that extra work took 53 minutes. A total of 69% of teenage students say they did homework, and that on average, they spent 1 hour 13 minutes doing it.

This insight has emerged from the educational project 91茄子, which so far has involved more than 19,000 students from 600 schools answering questions about their lives. For the first time this year, 91茄子 asked students whether they had done homework the night before filling in the online survey, and how long they spent on it.

鈥淭丑别 numbers are just a snapshot, but they are food for thought in the lively debate around homework,鈥� says 91茄子 co-director Rachel Cunliffe. 鈥淚t seems that everyone has an opinion on how much homework children should do 鈥� and more recently, we鈥檝e seen some education experts suggesting that children are, perhaps, better off playing after school rather than studying.鈥�

The survey also found that 74% of teen girls said they did homework the night before 鈥� but just 61% of teen boys. Some students said they did two or more hours of homework 鈥� 7% of all 6 to 12-year-olds and 15% of all 13 to 18-year-olds.

WHO鈥橲 DOING HOMEWORK?

Students who did homework the night before 91茄子:
All, aged 6-12: 77%
All, aged 13-18: 69%

Average time on homework the night before 91茄子:
All, aged 6-12: 53 mins
All aged 13-18: 1 hour 13 mins

Boys aged 6 to 12: 53 mins
Girls aged 6 to 12: 54 mins

Boys aged 13 to 18: 1 hour 5 mins
Girls aged 13 to 18: 1 hour 17 mins

Students were also asked to name their favourite singers or bands. Anyone with a daughter will not be at all surprised to hear that the girls鈥� favourite group is English-Irish boy band One Direction, formed out of the 2010 series of singing competition The X Factor in the United Kingdom. Next on the list is Taylor Swift, followed by Ed Sheeran, Justin Bieber and Beyonce. For boys, the top of the list is American singer-songwriter Bruno Mars, followed by Eminem, Macklemore, Imagine Dragons, and Coldplay.

91茄子 is a biennial online project that brings statistics to life in the classroom. Supervised by teachers, students aged between 10 and 18 (Year 5 to Year 13) answer 32 questions about their lives, many of them involving practical activities such as weighing and measuring, then become 鈥榙ata detectives鈥� as they analyse the results in class. This year, more than 1408 teachers have run CAS in their classrooms.

91茄子, now in its sixth edition, is a collaborative project involving teachers, the University of Auckland鈥檚 Department of Statistics, Statistics New Zealand and the Ministry of Education. It is part of an international effort to boost statistical capability among young people, and is carried out in Australia, the United Kingdom, Canada, the US, Japan and South Africa. The countries share some questions so comparisons can be made, but the majority reflect New Zealand students鈥� interests.

91茄子 co-director Professor Chris Wild, of the Department of Statistics at the University of Auckland, adds, 鈥淭丑别 survey produces data about kids, from kids, for kids, to enrich their learning about how to collect, explore and analyse data. But the project goes much further, by providing support to teachers.鈥�

This morning, Rachel Cunliffe spoke with Kathryn Ryan about the 91茄子 project:

• Bebo out as girls flock to Twitter – Central Leader 29 May 2013 p 14
• Leighton Smith and Larry Williams discussed the results on their Newstalk ZB radio shows.

Teenage schoolgirls are flocking to the microblogging service Twitter, according to early results from the educational project 91茄子. One in three teenage schoolgirls (37%) has reported having a Twitter account, up from one in four (23%) in 2011.

91茄子 co-director Rachel Cunliffe says the findings mirror overseas trends around Twitter, which was launched in 2006 and allows its users to send and read 鈥渢weets鈥� of up to 140 characters each.

鈥淭丑别 in the US has also found much higher use of Twitter by teen girls than teen boys,鈥� she says. 鈥淥ne explanation for this could be that teenage girls are generally more social and more communicative than teenage boys, and use Twitter to keep in touch with their friends.”

91茄子, which started on May 6 and runs until June 15, is a biennial online project that brings statistics to life in the classroom. Supervised by teachers, students aged between 10 and 18 (Year 5 to Year 13) answer 32 questions about their lives, many of them involving practical activities such as weighing and measuring, then analyse the results in class. This year, more than 1236 teachers from 565 schools all over New Zealand are running CAS in their classrooms, and the social media results are always of great interest to their students. The snapshot comes from the first 10,000 respondents.

But it seems their love affair with Facebook has peaked. Since the last 91茄子, in 2011, there has been no real change in the number of teenage school students with Facebook accounts. In 2009, just 33% of teens had a Facebook page, but by 2011, that figure had risen to 83%. This year, 83% said they had a Facebook page.

“There comes a point where it’s not really possible to grow the numbers anymore,鈥� says Cunliffe. 鈥淔acebook uptake among school students may well be at its limit. It will be fascinating to how those numbers have changed when we run the next 91茄子 in 2015.”

But the future looks shakier for the once-popular social networks Bebo and MySpace 鈥� they appear to be slipping from New Zealand teens鈥� lives altogether. In 2009, 63% of teenage school students had a Bebo page, but by 2011 that had fallen to 27%, and this year reached a new low of 11%. The music-focused MySpace has had an even worse trajectory, slipping from 17% in 2009 to 7% in 2011. This year, despite a January relaunch, MySpace hit 6%.

“Teens are early adopters of new social networks and apps and are quite happy to start afresh, setting up and building new profiles,鈥� says Cunliffe. 鈥淢any teens don’t know what Bebo is now, yet it was the dominant social network only a few years ago.”
