Ministerial foreword
The Department of Basic Education (DBE) has pleasure in releasing the second
edition of the Mind the Gap study guides for Grade 12 learners. These study
guides continue the innovative and committed attempt by the DBE to improve the
academic performance of Grade 12 candidates in the National Senior Certificate
(NSC) examination.
The study guides have been written by teams of exerts comprising teachers,
examiners, moderators, subject advisors and coordinators. Research, which
began in 2012, has shown that the Mind the Gap series has, without doubt, had
a positive impact on grades. It is my fervent wish that the Mind the Gap study
guides take us all closer to ensuring that no learner is left behind, especially as
we celebrate 20 years of democracy. Matsie Angelina Motshekga, MP
The second edition of Mind the Gap is aligned to the 2014 Curriculum and Minister of Basic Education
Assessment Policy Statement (CAPS). This means that the writers have considered
the National Policy pertaining to the programme, promotion requirements and
protocols for assessment of the National Curriculum Statement for Grade 12 in
2014.
The CAPS aligned Mind the Gap study guides take their brief in part from the
2013 National Diagnostic report on learner performance and draw on the Grade
12 Examination Guidelines. Each of the Mind the Gap study guides defines key
terminology and offers simple explanations and examples of the types of questions
learners can expect to be asked in an exam. Marking memoranda are included to
assist learners to build their understanding. Learners are also referred to specific
questions from past national exam papers and examination memos that are
available on the Department’s website – www.education.gov.za.
The CAPS editions include Accounting, Economics, Geography, Life Sciences,
Mathematics, Mathematical Literacy and Physical Sciences Part 1: Physics and
Part 2: Chemistry. The series is produced in both English and Afrikaans. There are
also nine English First Additional Language (EFAL) study guides. These include
EFAL Paper 1 (Language in Context); EFAL Paper 3 (Writing) and a guide for each
of the Grade 12 prescribed literature set works included in Paper 2. These are
Short Stories, Poetry, To Kill a Mockingbird, A Grain of Wheat, Lord of the Flies,
Nothing but the Truth and Romeo and Juliet. (Please remember when preparing
for EFAL Paper 2 that you need only study the set works you did in your EFAL class
at school.)
The study guides have been designed to assist those learners who have been
underperforming due to a lack of exposure to the content requirements of the
curriculum and aim to mind-the-gap between failing and passing, by bridging
the gap in learners’ understanding of commonly tested concepts, thus helping
candidates to pass.
All that is now required is for our Grade 12 learners to put in the hours required
to prepare for the examinations. Learners, make us proud – study hard. We wish
each and every one of you good luck for your Grade 12 examinations.
