The advent of largescale tutoring systems has given rise to an abundance of data in the form of learner question-answer logs in which signatures of misconceptions can be mined. In this work, we explore the extent to which collected expert misconception diagnoses can be generalized to held-out questions to add misconception semantics. We attempt this generalization by way of a question-answer neural embedding trained on chronological sequences of learner answers. As part of our study, we collect natural language misconception diagnoses from math educators for a sampling of student answers to questions within four topics on Khan Academy. Drawing inspiration from machine translation, we use a multinomial… Continue Reading →

eric.ed.gov har udgivet: The U.S. arm of technology giant Siemens Corp. recently reported it has 3,000 jobs open because of the dearth of skilled workers. More than half of those open jobs require science, technology, engineering and math (STEM) skills. A recent study by ManpowerGroup found that a record 52 percent of U.S. employers have difficulty filling critical positions within their companies–up from 14 percent in 2010. Many of these jobs require a strong background in STEM, but American colleges are producing fewer math and science graduates. This has led to a skills mismatch in our country. The bottom line is that STEM workers are more likely to be employed and more likely to earn better pay. The unemployment rate for workers who only have a high school degree is… Continue Reading →

Mathematics education is a key to increasing the later professional and citizenship opportunities of students and mathematical understanding influences decision making in all areas of life. Additionally, math failure correlates highly with referral to special education, grade retention, and school dropout and are cumulative and worsen with time, therefore, early identification and intervention is important. Empirical data from Flanders, the Dutch-speaking part of Belgium, was used, which makes an interesting case study as it has a strong tradition of separate special education. Study results indicated that students with special educational needs are better off in mainstream education than in a special education school, at least as far as mathematics goes. Also,… Continue Reading →

eric.ed.gov har udgivet: Teacher collaboration has been recognized as a vital component to student success. This project represents an evaluation of the researchers’ initial efforts toward providing in-service education for teachers focused on collaboration between math and CTE teachers. The purpose of this study was to (1) describe selected characteristics of secondary teachers of math and CTE, (2) describe their perceptions concerning the “value of” and their “willingness to implement” the instructional practices and activities presented during a professional development seminar, and (3) assess their views about the use of emerging technology for teacher collaboration. Survey responses indicated that using the Math-in-CTE Model was valued. Overall, respondents valued technology but seemed a bit reserved about the likelihood of implementing and using technology. Results imply that teachers with positive attitudes and… Continue Reading →
