Ontological Clarity, Cognitive Engagement, and Conceptual Model Quality Evaluation: An Experimental Investigation

Simon Milton, Jayantha Rajapakse, Ron Weber
2012 Journal of the AIS  
We tested our theory using an experiment involving forty-eight expert data modeling practitioners. Their task was to find as many defects as possible in a conceptual model.  ...  In this light, we propose a theory in which two factors have a material impact on the effectiveness of conceptual model quality evaluation work: (a) the ontological clarity of the conceptual models prepared  ...  Acknowledgements An earlier version of this paper was presented at the 19th Annual Workshop on Information Technologies and Systems, Phoenix, Arizona, USA, 14-15 December 2009.  ...

Language-related Episodes Patterns Engendered in L2 Classrooms: Pedagogical Translation Tasks Versus Monolingual Writing Tasks

Siowai Lo
2021 International Journal of Linguistics Literature & Translation  
Inductive thematic analysis shows that LREs produced in the concerned experimental tasks included 'concern-based LREs' and six different types of 'response-based LREs'.  ...  The present study was conducted in an authentic class environment and consisted of two experiments.  ...  The first finding reveals that discussions in the T-group were comprised of many more responses to concerns compared to the NT-group.  ...

A Comparison of the Effectiveness of a Closed Task and an Open Task

Rintaro SATO
2005 The Bulletin of the Kanto-koshin-etsu English Language Education Society  
As a closed task, play-acting was chosen, As an open task, a skeleton dialogue and interview were chosen, In the play-acting task, students memorized a model dialogue to have a conversation.  ...  conversation, The results showed that both types oftask were efTective for gramrriar acquisition, and it was revealed that the closed task was more effective than the open tasks.  ...  Closed task According to Ellis (2003) , open tasks are those which do not have a predeterrnined solution and are open in nature because learners have the freedorn to decide on the solntion.  ...
