Questions and CORRECT Answers
Block Design General Directions - CORRECT ANSWER - 1) Make sure they are seated
directly facing the edge of the table.
2) Say 'work as fast as you can' if you believe they are simply playing with the blocks.
3) Items 1-3 have two trials each. You do not need to do trial 2 if trial 1 was correctly done, but
administer trial 2 if they fail trial 1.
4) If the child attempts to duplicate your exact design (side faces of the model, point to the top
face of the blocks and say 'only the tops of the blocks need to be the same.'
Block design: How do you present the items? - CORRECT ANSWER - 1) Participation:
Items 1-3 are presente as a model you construct from the pictured design in the stimulus book.
The model is left intact as the child constructs the design according to the pictured design and the
model.
Item 4-13 are presented as pictured in the stimulus book.
2) Present only the number of blocks that are needed.
3) Place the blocks with a variety of surfaces facing up. For item 1-3 each block should have a
different side facing up.
For Items with 4 block, there should be only one red and one white facing up.
For items with 9 blocks, there should be only two red and two white facing up.
4) The stimulus book should be close enough to them and on the same side as their writing hand.
During items 1-3 the model should be directly next to the stimulus book, and on the opposite side
of their writing hand.
Block Design: How does the child present the pattern? - CORRECT ANSWER - They
should be parrallel to the edge of the table, i.e. they do not rotate the model and/or stimulus book.
, The child should not construct the design on top of the stimulus book. rather say: 'yours should
be over here'
Block Design: What types of errors can children make? - CORRECT ANSWER - You do
not let them move to the next item until these errors have been corrected or until the time limit is
reached. (Ask Ana).
1) Rotation Errors:
A rotation of over 30 degrees is considered a rotation error. Correct only the first time this
happens. Do not correct further.
Rotations of under 30 degrees are not considered errors, but may be noted for interpretive
purposes.
Score using: clockwise or anticlockwise arrows and >30 degrees.
2) Gap and Misalignment Errors
Gaps larger than 1/4 inch are penalised.
Misalignment that exceeds 1/4 inch are penalised.
3) Where a child might put 3 blocks in a row when constructing a 2x2 design. Only penalise at
the time-limit.
Score using: BDde
Block Design: General scoring rules? - CORRECT ANSWER - Record completion time in
seconds.
Note down if there are rotation errors, dimension errors, gap or misalignment errors if they
remain uncorrected at the time limit, even if they have finished working before the time limit has
expired.
Record aditional information where applicable.
Block Design Scoring for Items. - CORRECT ANSWER - 1-3:
Score 2 points if trial item 1 correct
