**Assessment, remedation & pre-requisite knowledge for mathematical literacy**

Great resource for Arnout http://www.brombacher.co.za for mathematical literacy. During April 2008 Brombacher and Associates ran a four-day workshop for FET College lecturers on the assessment and remediation of the pre-requisite knowledge and skills assumed to be necessary for students to be able to study Mathematical Literacy. The workshop was presented by Aarnout Brombacher and Marc North. It focussed on the use of pre-tests to determine the knowledge and skills that college students have at the start of the programme and on the teaching of the necessary knowledge and skills in those cases where the students do not have these.

**Assessment and remediation of the pre-requisite knowledge and skills for Mathematical Literacy**

Number booklet coverDuring April 2008 Brombacher and Associates ran a four-day workshop for FET College lecturers on the assessment and remediation of the pre-requisite knowledge and skills assumed to be necessary for students to be able to study Mathematical Literacy. The workshop, presented by Aarnout Brombacher and Marc North,was attended by one lecturer from each of the 50 FET Colleges.

The workshop focussed on the use of pre-tests to determine the knowledge and skills that college students have at the start of the programme and on the teaching of the necessary knowledge and skills in those cases where the students do not have these.

Click on the link above to access the pre-test and remediation materials developed for the workshop as well as the powerpoint slide shows that supported the teaching these could be used by college lecturers in their remediation efforts.

**It’s all cricket’s fault**

Mathematics is used in interesting, and often less than accurate, ways. Newspapers present graphs showing apparently correlated variables, but with a little thought, some of the time you will find that whilst it looks like two variables are connected, there is actually no cause and effect. Sometimes this is because there is a third factor causing the movements in the variables — for example, if it is hot and sunny, sales of sunscreen lotion increase, as do sales of air-conditioners. If you plot these sales against each other, you find a correlation. However, they are only connected because of a third variable, the summer weather. Of course, an unscrupulous media can draw connections where they don’t exist for more political ends, such as blaming an increase in crime on the sales of hooded sweatshirts. And politicians have been known to confuse cause and effect, thinking that a local crime increase is due to the increased police presence, rather than the other way around.

**Overview**

Mathematical Literacy was introduced as a subject in 2006 with 11 students and has steadily grown since then. Two classes of matrics are currently completing their studies in this subject.

**Brief Policy**

Mathematical Literacy is a choice subject in Grades 10–12. Mathematical Literacy provides students with an awareness and understanding of the role that mathematics plays in the modern world. It is a subject driven by life-related applications of mathematics. It enables students to develop the ability and confidence to think numerically and spatially in order to interpret and critically analyse everyday situations and solve problems.

**Homework**

Classwork exercises are given daily and homework is usually given daily.

**Tests and forms of Assessment**

There are 2 controlled tests in Term 1 (one open-book), 1 in Term 2 and 2 in Term 3. Other assessment includes a research project, a source-based project, assignments, worksheets, class tests and formal examinations in Term 2 and 4.**Grade 10 Information**
