The Problem • In 2008, the national average ratio of students to computers was about 3. 8 • Teachers have difficulty gauging student performance over time • Parents would like to know how their kids are doing more regularly
Introducing multi. Learn • Educational program • Originally developed for use in India o Allows 4 students to use a computer • No way to view statistics…
Target Users • Teachers in Seattle schools o o Internet connected computers ~3. 8 to 1 ratio (students to computers) • 4 th - 5 th grade students o Experienced with computers o Home internet access • Seattle parents
Built based on feedback • • • Online access is essential Feedback is more important than grading Info provided by current systems can be overwhelming Current online feedback from games is not reliable Teacher want to see whole class stats o Problems the whole class are missing
Related Work • Multi. Mouse (~2006) –Allowing computer to recognize different users • Metamouse (~2009) –Legacy computer programs • Mouse Mischief (~2010) –add-in for Microsoft Power. Point 2007, 2010 –Simple short-term score page • “One Mouse per Child”
Related Work • Student Response System –“Clicker” price –Increase engagement and motivation –Presenting data: Historical Report, Comparison Report – 25. 1% of teachers use response to adjust instruction (The Effect of SRS… 2007)
What we’ve accomplished so far • Web Application o Implementation § PHP, Javascript, & My. SQL o Teacher interface § Teacher class list § Overall class statistics § Individual student view o Data conversion & DB management
Teacher Interface • Class view Add classes View class list View Individual Classes o Add Students o View Overall Stats o o o
Teacher Interface • Overall Statistics Class Percentages § Color coded o Student Table § Sortable o Student Graph § Color coded o
Teacher Interface • Individual Student o Ability to add comments for himself/herself, the parent, or the student o Allows parents to gain an insight into how their child is doing, and allows teachers to communicate easily to the childs parents o Students can see what they could work on and what they are doing well
Teacher Interface
Data Conversion & DB management • Client Side Application uses SQLite, Web Application uses My. SQL • PHP script converts SQLite file into My. SQL tables that are automatically updated in our database • My. SQL database can be created with a PHP script. • Allows for the database to be modular and easily deployed
Changes from original plan • Graphs Then: Now:
Changes from original plan • Database Schema New types of questions called for new schema Much of the data was going unused § Exact problem not important § Type of problem important o More work done client side § Quicker, less complicated queries o o
Changes from original plan • Rewriting multi. Learn o Given buggy code o Poorly documented o Written for. NET 3. 5 § Crashed when certain pin numbers were typed § ~5 lines of comments total § No documentation of Windows API usage § Compiling 32 vs 64 bit systems § Not supported by most computers § Used unreliable ADO database calls
What we’ve accomplished so far • Client application o Implementation: o multi. Learn o Error Handling o Automated data upload & download § C# and SQLite § Degrades gracefully if computer is disconnected from internet
Arhitecture - Principles Architecture - Principles • Components should be as general (reusable) as possible • It should be easy to modify the program to add new types of questions • Export summary data instead of detailed data for every question o We’ve reduced the number of SQL rows to merge as well as the complexity of server-side queries • Documentation is not optional!
Architecture - The Big Picture • What we wanted o Client Application o Web Application § Curriculum assessment tool § Data stored in SQLite database § Automated data upload § Displays statistics § Accepts upload of usage data § Allows teachers to customize what kinds of questions are asked § Makes it easy to deploy these customizations to many classroom computers instantly
"The Big Picture"
About that rewrite: • More coding than expected • But worthwhile because we could customize every aspect of the application Added games Exporting of summary data o Automatic uploading/downloading of user data o Control over what questions are selected o o § Previously done by AI
Usage
Prototype Demonstration
What’s Left - Server Side • Parent and Student access • Refining the interface • Additional graphs & charts • State/National Standards
What’s Left - Client Side • Support for proxies o Many schools use these to implement content filtering o Teacher customizable parent/student views • Add additional types of questions • Add additional teacher customization • Ensure it is fun for students
Timeline for remainder of quarter • Additional functionality (Week 9) o Parent/student login o Use of Multi. Spell data o Printing • Paper/poster (Week 10)
