Learning through collaboration between vocational teacher training institutions and workplaces: Barriers and contradictions
(Nordic Journal of Vocational Education and Training, 2022-02-09) Arinaitwe, Dinavence; Mifsud, Louise; Kato, Habib; Sannerud, Arne Ronny
In vocational education and training, the acquisition of relevant skills by learners is vital for their employability. It has been argued that institution–workplace collaboration facilitates this acquisition of relevant skills through availing authentic real-life learning situations. This study used the cultural–historical activity theory to identify and characterise challenges to learning through collaboration between a masters of vocational pedagogy (MVP) programme, vocational teacher training institutions and workplaces in Uganda. Data were obtained using in-depth individual interviews with purposively sampled actors in collaborative activities. The findings revealed that challenges manifesting as discursive contradictions occurred in different phases of implementing collaborative activities. In the planning and implementation phase, contradictions were linked to short time frames for collaborative activities, unsynchronised activity plans and contradictory working cultures. In the supervision of learning, contradictions arose from a lack of a common understanding of the objectives and work methods of the collaborative activities. A lack of feedback to actors, an absence of a collaboration focal person, and a lack of government policy limited participation in collaborative activities. These challenges were observed to lessen the focus on the MVP students’ learning, which ultimately affected the quality of work produced and interfered with the implementation of collaborative activities.
The potential of ensiled browse/maize forage mixtures of calljandra, gljricidia and leucaena for dairy cattle feeding
(Kyambogo University [ Unpublished work], 2005-03) Kato, Habib
The potential of ensiled browse/maize fodder mixtures of Callianc/ra calothyrsus, Gliricidia sepium or Leucaena leucocephala for dairy cattle feeding was assessed in five experiments. Experiment 1 examined the fermentation characteristics, and the effect of fermentation on the chemical composition and rumen degradation of the browses and maize silage. Maize silage fermented best with higher (P $ 0.05) levels of lactic acid (4.98% DM) and lower (P $ 0.05) pH values compared to browse silages. The level of NH3-N (% Total N) was higher (P $ 0.05), in maize silage than in browse silages. Degradation of dry matter, organic matter and nitrogen was highest with Gliricidia followed by maize, Leucaena and Calliandra was least degraded. Fermentation increased rumen microbial protein synthesis with Gliricidia, Leucaena and maize forage but not with Calliandra. Experiment 2 assessed the fermentation characteristics, chemical composition and rumen degradation of ensiled browse/maize fodder mixtures in proportions of 0 to 50% browse (DM basis). Butyric acid and lactic acid levels and pH were low at all levels of browse addition. The levels of NH3-N were lower (P $ 0.05) with browse addition levels above 10% indicating less proteolysis with higher levels of browse addition. Maximum degradation of OM, OM and N occurred at 10 - 20% levels of browse addition. Estimated RMP synthesis consistently decreased with higher levels of Calliandra and Leucaena addition to the silage, but increased with higher levels of Gliricidia addition.
