Muntlig kommunikation i engelskundervisningen - en empirisk studie : Vad motiverar elever i årskurs 4-5 till att bli muntligt aktiva i klassrummet?

Den svenska kursplanen i engelska är utformad utifrån en kommunikativ språksyn. Elever ska därför utveckla en allsidig kommunikativ förmåga genom att bland annat använda språket muntligt. Det finns dock forskning som visar att många elever upplever en rädsla inför att tala på målspråket, vilket försvårar det kommunikativa lärandet. Vad som motiverar elever till muntlig aktivitet är därmed en väsentlig fråga. Dessvärre finns det få svenska studier som berör ämnet. Syftet med denna studie var därför att undersöka vad som motiverar elever i årskurs 4-5 till att bli muntligt aktiva i engelskundervisningen. Forskningsfrågorna fokuserar på när elever visar en vilja respektive ovilja att kommunicera, vad som motiverar elever till muntlig aktivitet samt vad lärare gör för att motivera elever till muntlig aktivitet. Dessa frågor har besvarats genom elva elevers och två lärares deltagande i en kvalitativ intervjustudie. Vad som främst visat sig motivera elever till muntlig aktivitet är ett tryggt klimat och en språklig säkerhet. Elever vill känna sig säkra på vad de ska säga och inte behöva vara oroliga för att säga fel eller att andra elever ska skratta åt misstag. Resultatet visar även på olika aktiviteter som kan vara fördelaktiga för att främja detta, såsom aktiviteter i mindre grupper. Vidare kan motiverande feedback också anses vara viktigt för att främja motivationen, med hänsyn till att många elever söker stöd av läraren vid muntliga aktiviteter för att känna sig säker i sin kommunikation. Studiens resultat samstämmer väl med den tidigare forskning som presenteras i studiens bakgrund, men för att kunna dra generella slutsatser efterfrågas ytterligare forskning inom ämnet.

Factors that Motivate Pupils in Grades 4-6 in Sweden to Speak English as a Foreign Language

This is an empirical study about factors that motivate pupils to speak English as a foreign language. The aim of this study is to investigate when pupils in the classroom situation, in Grades 4-6 in a school in Sweden, are motivated to speak English as a foreign language, and why they are motivated to speak English in these situations. To implement this study, questionnaires and interviews have been chosen as methods. 51 pupils in Grades 4-6 took part of the study. Since being able to communicate orally in a foreign language is of great advantage for one, and creates opportunities both for work and for study abroad, it is important for pupils to learn how to communicate orally in English. It is important to be able to use the language. In the English curriculum in Swedish schools, speaking English is a skill pupils must possess. Since this is the requirement it is important that teachers in Sweden relate to this. Many pupils do not like to speak in front of the rest of the class and some pupils only like to speak in informal situations. Therefore, teachers must use various strategies to create a willingness to communicate among pupils and various strategies to motivate them to speak English. The results show that pupils are motivated to use the language in class when they have recently been abroad. It also shows that they are motivated when they can decide the topic and speak about something they are interested in.

Validation and calibration of the activPAL™ for estimating METs and physical activity in 4-6 year olds

Examine the predictive validity of the activPAL™ metabolic equivalents equation, develop an activPAL™ threshold value to define moderate-to vigorous-intensity physical activities, and examine the classification accuracy of the developed moderate-to vigorous-intensity physical activities threshold value in 4- to 6-year-old children.

Development and characterization of the 2,4,6-trichlorophenol (2,4,6-TCP) aerobic degrading granules in sequencing batch airlift reactor

2,4,6-trichlorophenol (2,4,6-TCP) aerobic degrading granules were successfully developed in the sequencing batch airlift reactor. The key strategy used in cultivation of the granules was dosing glucose and acetate as co-substrates. After granulation, average concentrations of 2,4,6-TCP and COD in the effluent were less than 8mgL-1 and 59mgL-1, respectively. The removal efficiencies of 2,4,6-TCP and COD were above 93% and 90%, respectively. The specific degradation rate of 2,4,6-TCP peaked at 61mg 2,4,6-TCP gVSS-1h-1 when inoculated at the concentration of 400mgL-1. The extracellular polymeric substance (EPS) contents of the 2,4,6-TCP aerobic degrading granules were decreased compared with the contents in seed sludge. Two peaks attributed to the protein-like fluorophores were identified by three-dimensional excitation emission matrix (EEM) fluorescence spectra. The decrease of fluorescence parameters, e.g., peak locations, intensities, indicated quenching effect of 2,4,6-TCP on the EPS fluorescence. Meanwhile, the shift of peak position indicated chemical changes of the EPS.
