This paper presents the results of a research work carried out in order to develop a novel gaming model for formative knowledge assessment (FKA). The benefits of FKA are well acknowledged by educators as it aids for better learning. As FKA is more frequent, the students’ willingness to take frequent assessments is poor. Often the students expressed that they felt uncomfortable and this resulted in lack of active participation. These are considered as major challenges to be addressed. Hence, this research aimed to find a way to make the assessments interesting. Based on the positive responses for game-based learning, a theoretical model that integrates the principles of extensive games (EGs) and concept map (CM), namely concept tree game (CTG), has been defined and developed. Further, a qualitative research has been performed to evaluate the impact of the FKA model. Major data gathering techniques used in this work were a class test, proposed FKA method, participant observation, survey and focussed team interview. The data were analysed statistically and the results revealed that it has been effective and useful for educators in assessing the knowledge of students and for students, it aided them to know where they stand and helped them to learn effectively.
Ossifying fibroma (OF) is a rare benign tumor, which is a distinct entity, despite being closely related to fibrous dysplasia, according to WHO classification of 2005.1 It is commonly found in mandible and maxilla but rarely found in ethmoid sinuses, orbit and skull base.2-4 It commonly occurs in age group of 20 to 40 years,5,6 although rarely, it can present in all age groups. OF is more common in females than males.4,7 We describe here two cases of OF involving the ethmoid sinuses in young male patients which presented diagnostic dilemmas for us. We report these cases as the site of involvement, age group and sex of patients and diagnostic and management considerations imparted uniqueness to these cases.
