Assessment

Learning outcomes (LOs)

LO 1

Historical Enquiry

The learner will be able to use enquiry skills to investigate the past and present.

Assessment standards(ASs)

We know this when the learner:

1.1 continues to identify and select a variety of historical and archaeological sources relevant to an inquiry [finds sources];

1.2 evaluates the sources used (e.g. “Who created the source?”, “Is it reliable?”, “How useful is the information”) [works with sources];

1.3 interprets graphical and statistical sources [works with sources];

1.4 presents an original idea as part of an answer to questions posed [answers the question];

1.5 communicates knowledge and understanding by constructing own interpretation and argument based on the historical sources (including extended writing, artwork, graphics and drama); uses

information technology where available and appropriate [communicates the answer].

LO 2

Historical knowledge and understanding

The learner will be able to demonstrate historical knowledge and understanding.

We know this when the learner:

2.1 begins to make links between historical events and processes in different contexts in the same period [chronology and time];

2.2 recognises the cause and effects of events vary in importance [cause and effect];

2.3 explains changes in a wider historical and environmental context [change and continuity].

LO 3

Historical Interpretation

The learner will be able to interpret aspects of history.

We know this when the learner:

3.1 examines historical interpretation by asking relevant questions about the author of an historical source [source interpretation];

3.3 explains why history is not objective or neutral [source interpretation];

3.4 recognises that sense of identity may influence the events in the past are interpreted [influence on interpretation];

3.5 describes main features and uses of material remains of the past in a given context [representation of the past];

3.6 explains the importance of conserving our natural and cultural heritage (e.g. objects, buildings, heritage sites) [representation of the past].

Memorandum

Activity 1:

  • The facts accompanying the dates below are self-explanatory. Grade 8s have to strive to obtain full information, without having everything presented to them. Asking questions dealing with What? Where? and/or By whom? is a good recipe to follow to gain completeness.

TIME LINE : THE DISCOVERY OF GOLD AND DIAMONDS IN SAOR : EVENTS ON THE SA DIAMOND AND GOLD FIELDS

1852 : J.H. Davis discovers the first gold deposits on a farm near Krugersdorp.

1852 : Britain returns the Transvaal to the Transvalers with the signing of the Sand River Convention.

1854 : British control of the Orange Free State comes to an end with the signing of the Bloemfontein Convention by Britain and the Orange Free State.

1867: The first diamond is discovered near Hopetown.

1868 : Gold is discovered at Tati, north of the Limpopo.

1870 : Diamonds are discovered at Dutoitspan, later known as Kimberley.

1871 : Diamonds discovered at Vooruitzicht, another dry diggings.

1886 : Walker and Harrison’s find at Langlaagte becomes known as the main gold reef of the Witwatersrand.

1892 : Johannesburg linked by rail with Cape Town.

1895 : Johannesburg linked by rail with Durban.

Activity 2: SOURCE A and B

1.1 Any example from Source A, e.g. “24 carat gold is pure (100%) gold.”

1.2 Source A

1.3 The information is reliable, it has been the subject of research. OR: Dictionaries are reliable sources.

2.1 A primary source

2.2 An advertisement is an original source, just like an eyewitness report.

3. The ring would not show scratches as easily. The ring is cheaper. / 10 /
