Computers in Education
The proliferation of computing devices, such as laptops and desktops, in the classroom has forever changed how students learn. According to the Teaching with Technology survey, conducted by Campus Technology, Traditional laptops and desktops most common form of instructional technology used in the classroom. They are both used in 82 percent of learning environments. It is because of this prevalence that a Microsoft Windows based multi-media graphical system was developed to enlighten interested individuals about the possible construction methods likely employed in the creation of the St. George Church in Lalibela, Ethiopia. St. George’s Church in Lalibela, Ethiopia is an ancient Zagwe Dynasty monument created between AD 1137 and AD 1270. St. George’s Church is a UNESCO World Heritage Site that is often touted as the 8th Wonder of the World. St. George’s Church is visited by thousands of tourists and religious pilgrims every year. Among the many unique features of St. George’s that set it apart from most other constructions are the fact that is an hypogea, excavated into the ground instead of built up, and it is monolithic, hewn from one solid piece of rock. Learners can explore the possible construction methods used in the construction of Saint George’s Church from an engineering perspective, resulting in an explanation of the probable construction methods used in the construction of Saint George’s Church. Reliable information regarding the construction of St. George’s Church from an engineering perspective is sparse. Based on the information that is available, two distinct possible construction methods have been developed to describe the creation of St. George’s Church: MEOI (Measure, Excavate, Outside, Inside) and MSOI (Measure, Simultaneous excavation, Outside, Inside) When learners use the multi-media system, they are greeted by a Welcome Screen Tab. There are six other such tabs that comprise the multimedia system. The other tabs include a History tab that features a brief written history of St. George’s Church along with the option to view two Youtube based videos. There is a dimension tab that provides the physical dimensions of St. George’s Church. The Material tab allows learns to select the relative hardness of volcanic tufa from which the hypogea could be fashioned. There is a Construction tab which allows the learner to select whether they want to “virtually build” St. George’s using ancient, or modern tools: select the MEOI, or MSOI construction method: and choose the size of the construction labor force while receiving information about the selections made. There is also a Decision Tree tab. Using the multi-media system, learners have the option to “virtually build” St. George’s Church utilizing materials of varying hardness, modern tools, and varied labor force sizes to gain a more thorough exploration of the thought processes that brought St. George’s Church to fruition. Use of the multi-media system may potentially inspire learners to develop sustainable modern construction methods based on ideas used back in ancient times.
