Read,write, touch: Co‐construction and multiliteracies in a third‐grade digital writing exercise

Many researchers and educators believe that reading and writing instruction needs to change in order to reflect the multimodal, technological, interactive nature of communication today. To date, few studies have examined how touchscreen devices may influence primary school students' reading and writing practices. Guided by Vygotsky's notion of co‐construction and aspects of the New London Group's multiliteracies framework, we built an original multimodal tablet tool and examined how 51 third graders in Costa Rica used it to co‐construct and design meaning in a reading‐to‐writing activity. The first aim of this study, therefore, is to understand how multimodality and technology can work together to support young people's reading and writing. Secondly, we asked how a specific interactive, touchscreen feature might positively contribute to third graders' writing samples. The key findings were that the tool used in this study encouraged a broad range of writing practices, that the touch feature supported co‐construction, and that the careful integration of touchscreen features can engage and motivate students in reading and writing activities.     

Non-target screening of Allura Red AC photodegradation products in a beverage through ultra high performance liquid chromatography coupled with hybrid triple quadrupole/linear ion trap mass spectrometry

The study deals with the identification of the degradation products formed by simulated sunlight photoirradiation in a commercial beverage that contains Allura Red AC dye. An UHPLC–MS/MS method, that makes use of hybrid triple quadrupole/linear ion trap, was developed. In the identification step the software tool information dependent acquisition (IDA) was used to automatically obtain information about the species present and to build a multiple reaction monitoring (MRM) method with the MS/MS fragmentation pattern of the species considered.
