Becoming original: effects of strategy instruction

Visual arts education focuses on creating original visual art products. A means to improve originality is enhancement of divergent thinking, indicated by fluency, flexibility and originality of ideas. In regular arts lessons, divergent thinking is mostly promoted through brainstorming. In a previous study, we found positive effects of an explicit instruction of metacognition on fluency and flexibility in terms of the generation of ideas, but not on the originality of ideas. Therefore, we redesigned the instruction with a focus on building up knowledge about creative generation strategies by adding more complex types of association, and adding generation through combination and abstraction. In the present study, we examined the effects of this intervention by comparing it with regular brainstorming instruction. In a pretest-posttest control group design, secondary school students in the comparison condition received the brainstorm lesson and students in the experimental condition received the newly developed instruction lesson. To validate the effects, we replicated this study with a second cohort. The results showed that in both cohorts the strategy instruction of 50 min had positive effects on students' fluency, flexibility and originality. This study implies that instructional support in building up knowledge about creative generation strategies may improve students' creative processes in visual arts education

Effective School Improvement in Mathematics

This article addresses the evaluation of the Mathematics Improvement Programme. The results show that the programme improved the learning results of pupils in 3 with half a standard deviation and reduced the percentage of struggling pupils to less than 1%. Fifteen percent of the variance in pupil results is to be explained at the school level. About a quarter of this 15% can be explained by differences between the experimental and the comparison group. All of this condition variance is explained by the experimental variables. Five out of 10 implementation features contribute significantly to differences in pupil results
