Abstract
In this study a Physics Research Articles Word List (PRAWL) is built, which includes the most extensively used
English vocabulary in the genre of physics research articles outside the most frequent general-purpose vocabulary. PRAWL can be of
great use in English for Physics teaching and learning. This discipline-specific academic word list was produced from a corpus of
1.25 million running words, consisting of 200 physics research articles. PRAWL contains 929 words and has a 17.48% coverage in the
corpus it was derived from. Together with 2,000 high-frequency general-purpose words, as well as words bearing no or minimal
learning load, PRAWL reaches a coverage close to 95% in this corpus. We validate PRAWL in three independent corpora and also
discuss the pedagogical implications and recommendations regarding its use. The list is intended for students of physics who do
not have a command of English which is sufficiently adequate for reading research articles in it without outside support.
Keywords: physics research articles, word list, lexical frequency, lexical coverage, ESP, EAP
Resumen
Crear y validar una académica lista de palabras en inglés basada en corpus para física
En este estudio se ha construido una Lista de Palabras de Artículos de Investigación de Física (PRAWL), que
incluye el vocabulario inglés más utilizado en el género de artículos de investigación de física fuera del vocabulario para uso
general más frecuente. PRAWL puede ser de gran utilidad en inglés para la enseñanza y el aprendizaje de la física. Esta lista de
palabras académicas específicas de disciplinas se produjo a partir de un corpus de 1,25 millones de palabras corrientes y consta
de 200 artículos de investigación de física. PRAWL contiene 929 palabras y tiene una cobertura del 17,48% en el corpus del que fue
derivada la Lista PRAWL. Junto con 2.000 palabras para uso general de alta frecuencia, así como palabras que tienen una carga de
aprendizaje mínima o nula, PRAWL alcanza una cobertura cercana al 95% en este corpus. Validamos PRAWL en tres corpus
independientes y también discutimos sobre las implicaciones pedagógicas y las recomendaciones con respecto a su uso. La lista va
dirigida a estudiantes de física que no tienen un dominio del inglés que sea lo suficientemente adecuado para leer artículos de
investigación en inglés sin algún apoyo externo.
Palabras clave: artículos de investigación de física, lista de palabras, frecuencia léxica, cobertura léxica, ESP, EAP
