What is it worth?

Before you apply the IB assessment rubric one square at a time, read these general comments.

1 There are two people listed as authors - IB does not have group grades.

2 The barely hidden hypothesis is that ...... "The measurements for these particular objects will be consistent with the statements found in the text book." Stated this way the hypothesis is reasonable but of little real value.

3 There is no evidence of planning other than to get the assignment done as painlessly as possible.

4 There has been no attempt find the likely errors in measurements by repeating one measurement several times to find half the range or a simillar measure of error.

5 There are no diagrams to define symbols.

6 There are no tables of actual measurements with errors. There is just no data!

7 The original work had no proper symbols for the two coefficients.

8 The original calculation of acceleration was incorrect.

9 The summary table is well presented but there are no raw values to allow checking.

10 The evaluation was faulty - the measurements were probably fine - the problem was a lack of understanding.

11 There is no evidence of collaboration, to find out what had in fact gone wrong.

12 Finally the whole thing is not written in the past passive - the repeated use of "We ..." is irritating.

13 They cite Giancolli - I wonder if they actualy read it?

 

Here is the assessment sheet - apply it yourself. Can you find more than 10%?
