An integrated course for English medium of instruction teacher trainees in South Africa
Research regarding the specific needs of the L2MI teacher points to the need for developing a training course that not only ensures advanced levels of personal proficiency in the medium of instruction, but also certifies the ability to apply methodological and presentational skills that enhance and promote learning in the L2MI subject content classroom. This article describes the design and implementation of an integrated course for second language medium of instruction (L2MI) teacher trainees. Based upon the profile of effective L2MI and deriving outcomes for language, methodological and presentational skills from this, the course is both practical and functional. The hybrid model that was used for the design of the course is based on a combination of an Outcomes-based and a Backward Design model for course design and consists of six distinctive steps. The integrated course was developed within the BEd teacher-training programme and introduced for one semester. The students and the course instructor reviewed some aspects of the course and the Instructional Plan afterwards.
Pasteurella haemolytica serotype 1 colonization of the nasal passages of virus-infected calves.
Nasal passages of calves with a virus-induced respiratory tract disease became colonized by Pasteurella haemolytica serotype 1 after they were inoculated intranasally with P haemolytica. Inoculation with infectious bovine rhinotracheitis virus caused a more severe clinical illness and resulted in a greater degree of colonization with P haemolytica than developed after inoculation with parainfluenza-3 virus. Nasal passages of parainfluenza-3 virus-inoculated calves were colonized to a greater degree with P haemolytica than were those of healthy, nonstressed calves. Calves were susceptible to P haemolytica colonization during or shortly after virus-induced illness, even though they had been previously exposed to P haemolytica and had serum antibody and nasal secretion antibody to P haemolytica.
