“The Text Comes First” – Principles Guiding EFL Materials Developers’ Vocabulary Content Decisions

Vocabulary in an EFL classroom

Despite our increasing knowledge on vocabulary and its learning and teaching, the reality in a classroom may still be somewhat more traditional. This paper looks at how lexical knowledge is portrayed in an EFL classroom and in pupils’ ideas of words. The data derives from a longitudinal study that investigated the development of children’s metalinguistic awareness during their first six years a...

the impact of morphological awareness on the vocabulary development of the iranian efl students

this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...

Thermal properties of materials from first principles

In the search of clean and efficient energy sources intermediate temperature solid oxide fuel cells are among the prime candidates. What sets the limit of their efficiency is the solid electrolyte. A promising material for the electrolyte is ceria. This thesis aims to improve the characteristics of these electrolytes and help provide thorough physical understanding of the processes involved. Th...

Discovering materials with first-principles computational methods

Predicting the arrangement of atoms in materials is of fundamental importance for the discovery and design of new materials. The discovery and development of stronger, cheaper, lighter, etc., functional materials can help to extend the steady progress of technology to which we have become accustomed, and to enable future technologies. It is increasingly being recognised that computational model...
