Abstract
Announced in 2006 and 2010, the two versions of standard geography curriculum in high school emphasized the usage of geographic abilities, especially the introduction of maps and geographic information systems (GIS). The crucial learning target is thinking and solving geographic questions by applying GIS knowledge and tools.
Since the curriculum standard announced, many public resources have invested in improving GIS facilities and enhancing course training. However, many teachers are still having problems to teach with GIS and operate GIS software. The major causes include high requirements of technique, lack of instructional time, and high price of commercial GIS software packages and computer equipment.
On the other hand, many teachers began to teach with free-download software or web GIS such as Google Earth or Google Maps in classes. The advantage of these tools is that teachers can access massive geospatial data, including satellite image and vector format layers. But, in a strictly definition, the GIS should include functions of processing and analyzing geospatial data. Neither Google Earth nor Google Maps can provide these functions.
To address these problems, this research developed a web-based GIS website focusing on 10th grade GIS instruction. The website is composed of a base map and GIS functions. First, the base map in the webpages is generated by Google Maps API scripts, the same as the official Google Maps interfaces. Second, the ArcGIS Server published series of web GIS services such as web mapping services (WMS) and geo-processing services. To enable the web GIS services work in the client’s web browser, the website used the extension JavaScript script released by ESRI. By using GIS functions through this website without software installation, teachers and students can improve the efficiency of GIS instruction.
