Teaching Strategies
Picture Dictation
The teacher describes a picture, or sequence of pictures, to students who draw what they hear. The aim is for close listening, the drawing should be quick and simple.
Normally the exercise takes about 20-30 minutes, depending on the length of the dictation.
Prepare a text that is appropriate to the level of the learners, is written in simple visual terms and has a series of steps.
- Tell the students the number of visuals they will be drawing, or the shape of the picture if there is only one.
- Read each step aloud to the class twice, allowing time for the drawing.
- Where there is a series of visuals, the students work in pairs to retell the sequence.
- The students check their visual against the original.
Variations:
- Have one or two confident students drawing their pictures on the board so that the other students can copy when they are unsure (if they judge they are correct).
- Picture dictations can be done in pairs, one students reading and one drawing.

Year 11 Science: Meiosis
| The pairs separate, with one of each pair going towards each pole along
the spindle fibres. |
| The DNA of each chromosome is replicated to form two chromatids per chromosome.
This happens as the nuclear membrane begins to break down. |
| The spindle fibres pull the chromatids of each chromosome apart. The chromatids
move along the spindle fibres towards the poles. |
| The nuclear membranes around each haploid nucleus begin to break down. |
| The cytoplasm of the cell divides to form two haploid cells i.e. each
cell has half the number of chromosomes of the original cell. |
| The chromosomes line up in homologous pairs along the equator of the cell.
While in pairs, homologous chromatids can exchange lengths of their DNA,
mixing up the genes. |
| The cytoplasm of each cell begins to divide and the nuclear membranes
form. |
| A cell has two homologous pairs of chromosomes in its nucleus, one long
pair and one short pair. |
| The end result of meiosis is 4 haploid cells each with a different combination
of genes. These cells mature to become the gametes. |
| The chromosomes again line up along the equator, only this time in single
file. |
