Development of a tablet application for the screening of receptive vocabulary skills in multilingual children: A pilot study

For professionals working with multi-lingual children, detecting language deficits in a child’s home language can present a challenge. This is largely due to the scarcity of standardised assessments in many children’s home languages and missing normative data on multilingual language acquisition. A common approach is to translate existing English language vocabulary measures into other languages. However, this approach does not take into account the cultural and linguistic differences between languages. This pilot study explored whether English and home language receptive vocabulary skills can be objectively and reliably screened using a tablet application. Preliminary data on mono- and multilingual vocabulary skills was collected from 139 children aged 6-7 years. A tablet application was designed to assess children’s receptive vocabulary in both English, and an additional eight languages using a four choice picture paradigm. Linguistically controlled and pre-recorded target items are presented orally via the tablet in each language and responses are made via the touchscreen and automatically scored. The English version of the test was administered to 67 mono- and 72 multilingual children, while 38 multilingual children also completed the test in their home language. Test criteria measures, including reliability and concurrent validity showed satisfactory results. These findings suggest that the tablet application could be a useful tool for professionals to screen receptive vocabulary skills in mono- and multilingual children. Limitations of the first version of the RVS and future steps are discussed

Working Memory Underpins Cognitive Development, Learning, and Education

Working memory is the retention of a small amount of information in a readily accessible form. It facilitates planning, comprehension, reasoning, and problem-solving. I examine the historical roots and conceptual development of the concept and the theoretical and practical implications of current debates about working memory mechanisms. Then I explore the nature of cognitive developmental improvements in working memory, the role of working memory in learning, and some potential implications of working memory and its development for the education of children and adults. The use of working memory is quite ubiquitous in human thought, but the best way to improve education using what we know about working memory is still controversial. I hope to provide some directions for research and educational practice
