Hu and Nation's (2000) study, which stipulated that second language (L2) readers need to be familiar with 98% of lexical items for adequate text comprehension, has become highly influential in L2 vocabulary research and pedagogy. However, the 98% critical threshold figure is based on findings from a research project in which a regression analysis…

Background: Governments in low-income countries and donors have invested the equivalent of hundreds of millions of dollars in enhancing reading outcomes. Although reliable measures exist to assess emergent literacy skills in international contexts, there is little consensus on the assessment of reading comprehension. Methods: Using data from 5,389…

It is argued that corporal punishment produces bad outcomes in both the short run and the long run. Instead of making students more attentive or motivated, corporal punishment leads to more delinquent behavior. In most developed countries, corporal punishment is banned in schools. However, in many developing countries, even if corporal punishment…

This paper illustrates similarities and differences between two international surveys that assess adults' skills: the Programme for the International Assessment of Adult Competencies (PIAAC) and the Skills Towards Employment and Productivity (STEP) survey. In particular, the paper highlights the issues that can arise for researchers interested to…

Background/Context: Despite increasing school enrollment, significant literacy gaps persist in developing countries, with many children unable to read by age 10. This paper evaluates "M'ap Li Net Ale," a comprehensive intervention aimed at improving early-grade reading skills in Haiti, a context characterized by limited government…

This paper uses recent evidence from international early grade reading programs to provide guidance about how best to create appropriate targets and more effectively identify improved program outcomes. Recent results show that World Bank and US Agency for International Development-funded large-scale international education interventions in low-…

The PISA for Development (PISA-D) project aims to make PISA more accessible and relevant to middle- and low-income countries by introducing new features to the assessment, including tests that are specially designed to measure lower levels of performance, contextual questionnaires that better reflect the situations of 15-year-olds across a diverse…

Fifty-three percent of Grade 4 learners cannot read for meaning in low- and middle-income countries despite an investment of between 33-49% of education expenditure on primary education. Teaching children to read in the early grades is fundamental to building resilient education systems, as the ability to read early in life is a great predictor…

Few developing countries participate in external educational evaluations. Information gaps on education quality make it imperative to expand such evaluations. Furthermore, international comparability across different evaluations should be improved. In addition, data from evaluations must be combined with data on access or coverage. Finally,…

The differential patterns of grade progression have direct implications for the calculation of learning profiles. Researchers measure learning in primary school using survey data on reading and math skills of a nationally representative, population-based sample of children in India, Pakistan, Kenya, Tanzania, and Uganda. Research demonstrates that…

Over the past decade, international and national education agencies have begun to emphasize the improvement of the quality (rather than quantity) of education in developing countries. This trend has been paralleled by a significant increase in the use of educational assessments as a way to measure gains and losses in quality of learning. As…

In low-income countries, private schools are perceived as superior alternatives to the public sector, often improving achievement at a fraction of the cost. It is unclear whether private schools are as effective in middle-income countries where the public sector has relatively more resources. To address this gap, this paper takes advantage of…

This report reviews the major international and regional large-scale educational assessments, including international surveys, school-based surveys and household-based surveys. The report compares and contrasts the cognitive and contextual data collection instruments and implementation methods used by the different assessments in order to identify…

In 19 (sub)samples from seven countries (United States, Austria, Germany, Costa Rica, Ecuador, Vietnam, Brazil), we analyzed the impact of parental education compared with wealth on the cognitive ability of children (aged 4-22 years, total N = 15,297). The background of their families ranged from poor indigenous remote villagers to academic…

Educational access in developing countries has improved significantly in recent years, but less evidence is available on learning and learning progress in comparative perspective. This paper employs data from Young Lives to examine levels and trends in cognitive skill development and the links to enrolment in school across the four study countries…
