Created by a 15-year veteran teacher and launched by 250 teachers on Kickstarter. Quick Key’s mobile grading app easily grades paper quizzes and assessments with just one device, anywhere, even without any network connection at all. Paperless classroom? With Quick Key you can send a quiz to your students’ Chromebooks, laptops, or mobile devices (BYOD). Pencil and Paper Classroom? You can grade 100 paper tests in less than 5 minutes, using nothing but the camera on your iPhone or iPad, and our scantron-style bubble sheets are 100% free! Quick Key is the only mobile grading solution that is secure enough for districts, affordable enough for schools, and easy enough for everyday classroom use. Are you the leader of a 1:1 school, or a district in transition to 1:1? Quick Key effortlessly combines results from 1:1 classrooms and paper classrooms. And it provides automatic top-level reporting of key data, so you can focus on student growth, not managing your data. Quick Key was originally built for teachers doing ungraded assessment for learning and frequent formative assessment in the classroom, using nothing but their iPhone or iPad. But even if you don’t use daily exit tickets, Quick Key is perfect for quizzes, unit tests, district wide benchmark assessments, midterms and finals. It completely replaces the need for a scantron machine. Best of all, you never have to worry about getting your grades in at the last minute: Quick Key syncs with Google Classroom, exports data into any electronic gradebook , and sends grades directly into PowerSchool with one click. All your Quick Key data is secure, and we actively follow FERPA and COPPA best practice. *********************** Let’s talk teaching! *********************** During my 15 years in the classroom, I saw first-hand how my students excelled when I made formative assessments for learning part of my lessons. Now I am dedicated to empowering teachers to be creative and student-focused in a world increasingly driven by data. I would love to personally connect with you! Follow @4_teachers on Twitter to say hello and talk teaching and learning. You TEACH BIG™, we get your back! *********************** UPDATES *********************** This Release: easier than ever No more jumping around back and forth between screens. Everything you need to do is now intuitive and obvious. Now you don't have to create a course to give a quiz. Just make your quick answer key and scan. All your data syncs even faster. And sending a lot of data is no problem now. The last release: New bubble sheet designs that scan faster and stand up to photocopying, low-ink printers, and even more scribbles, erase marks, etc. New 10, 30, and 60-question Scantron-style bubble sheets. ================ Tell us what you think! ================ If you have enjoyed Quick Key please rate us on app store.

About

ScanGrader

Features
Read full description

ScanGrader is a complete solution for teachers to prepare and mark multiple choice tests using the device camera as a scanner. MAIN FEATURES ------------- ADVANCED IMAGE PROCESSING ScanGrader has developed an image-processing algorithm that consistently delivers precise results. COSTUMIZABLE ANSWER SHEETS Build personalized answer sheets directly from your iPhone or iPad, from 1 to 100 questions, with one or two answer sheets per page (in this case, you need to cut the page in half to distribute to students). You can define up to four labels, which will be printed on the answer sheets (name of school, name of class, teacher's name, data, etc.). You can also choose whether the answer sheets should contain a field for the students' signatures. VISUALIZE AND ANALYSE THE RESULT ScanGrader provides an Item Analysis tool, presenting, for each question, the difficulty level, the discriminant factor, and the frequency distribution of alternatives. You can see the results grouped by class, test, or students. All results can be seen using any of the groups: they are only grouped differently. If a test is applied to only one class, there is no difference if you choose to see the results by class or test. But if a test is applied to more than one class, choosing the class grouping will show the results for students in that class, while choosing the test grouping will show the results for all classes in which the test was applied. For class and test groupings, ScanGrader provides information and statistics about the grading: maximum points scored, minimum points scored, average points, standard deviation, median points, and others. EXPORT THE RESULTS You can export the results as a spreadsheet file in two formats: 1) Normal (ideal for importing the results of a test into your computer or on the school's server) 2) Complete (to use external tools for Item Analysis). REPORTS You can generate two types of reports as a PDF file: 1) Simple (a list of the students and their respective scores to post to the students) 2) Complete (a page for each student, containing a text with the student's choices for each question, the student's score, an image of the scanned answer sheet, and an image showing the result of the grading) TYPESET YOUT TEST To streamline the test preparation, keep the test's questions in a spreadsheet file (see the format required inside the app). Then, use the Typeset Questions tool to produce an elegant and professional PDF file to distribute to the students. You can typeset your test in one or two columns, and each question can also have an image, if necessary. You can also choose to set the key automatically for the test, with information kept in the spreadsheet file. SYNC BETWEEN DEVICES Sync students, tests, classes and results between your iOS devices using iCloud. SUBSCRIPTION Each time you use ScanGrader to grade a student answer sheet, that is counted as one 'grading'. Users without a subscription have access to all functionalities, but with a limit of 50 'gradings' per month (non-cumulative).  Users with an Annual Subscription (the only one available for ScanGrader) enjoy unlimited gradings throughout their subscription period.
