Modeling Styles in Business Process Modeling [PDF]

open access: yes, 2012
Research on quality issues of business process models has recently begun to explore the process of creating process models. As a consequence, the question arises whether different ways of creating process models exist. In this vein, we observed 115 students engaged in the act of modeling, recording all their interactions with the modeling environment ...

Models of the reading process [PDF]

open access: yesWIREs Cognitive Science, 2010
AbstractReading is a complex skill involving the orchestration of a number of components. Researchers often talk about a ‘model of reading’ when talking about only one aspect of the reading process (e.g., models of word identification are often referred to as ‘models of reading’).
