Small class size vs. evidence-based interventions

The Ministry of Education in France introduced a policy in 2002 that reduced class size to no more than 12 pupils in areas determined to have social difficulties and high proportions of at-risk pupils, called Zones d’Education Prioritaire (ZEP).

In order to evaluate the effectiveness and usefulness of this policy, researcher Jean Ecalle and colleagues in France examined the results of the policy-mandated class size reduction on the reading achievement of first grade (Year 2) pupils (Study 1), and compared them to the effects of an evidence-based literacy intervention on the reading achievement of at-risk children in normal-sized classes (20 pupils) (Study 2).

Rätt svar: 9 m2

Eftersom vi denna månad bara har fått in lösningar från Douglas så publicerar vi hans lösning.

Rätt svar: Det här problemet har flera svar beroende på hur man viker. Triangeln har arean 24 cm2. När man viker papperet minskar arean men den kan inte bli så liten som hälften. Douglas har gjort en lösning som visar på ett möjligt svar.

California’s positive outliers: Districts beating the odds

In this report, we summarize the results of a quantitative analysis that identifies districts in which students of color, as well as their White peers, have demonstrated extraordinary levels of academic achievement, measured by California’s new assessments in English language arts and mathematics, taking into account race and family income and education levels.

These results show, for the first time, which California districts and communities appear to have best supported the academic achievement of students in the first 3 years of the new assessments, controlling for the socioeconomic status of families in each district. We also examine some of the factors associated with their success.

We find that, aside from socioeconomic status, a major predictor of student achievement is the preparedness of teachers. The proportion of teachers holding less than a full credential (i.e., an intern credential, temporary or short-term permit, or waiver for their teaching position) shows a strong negative association with student achievement for all student groups.
