"Wheel spinning" is the phenomenon in which a student fails to master a Knowledge Component (KC), despite significant practice. Ideally, an intelligent tutoring system would detect this phenomenon early, so that the system or a teacher could try alternative instructional strategies. Prior work has put forward several criteria for wheel…

People re-identification has been a very active research topic recently in computer vision. It is an important application in surveillance system with disjoint cameras. This paper is focused on the implementation of a human re-identification system. First the face of detected people is divided into three parts and some soft-biometric traits are…

Open Online Courses can serve different purposes: in the case of Orient@mente at the University of Torino, they aim at facilitating the transition from secondary to tertiary education with automatic evaluation tests that students can try in order to understand their capabilities in - and their attitude towards - certain disciplines, and with…

This study examines the impact of "Promise" programs on postsecondary institutions' decision-making. Promise programs have garnered widespread attention in the U.S., especially after the announcement of the Kalamazoo Promise, but relatively little scholarly research. Promise programs provide grant aid to all students from a particular…

MOCCA-C is an assessment of adult reading ability designed for early diagnosis of reading problems, for formative assessment in reading intervention planning, for assessment of reading improvement over time, and for assessment of reading intervention outcomes. It uses both narrative and expository reading passages and it currently has four forms.…

Vocabulary knowledge is crucial to literacy development and academic success. Previous research has shown learning the meaning of a word requires encountering it in diverse informative contexts. In this work, we try to identify "nutritious" contexts for a word--contexts that help students build a rich mental representation of the word's…

Research in Educational Data Mining could benefit from greater efforts to ensure that models yield reliable, valid, and interpretable parameter estimates. These efforts have especially been lacking for individualized student-parameter models. We collected two datasets from a sizable student population with excellent "depth" -- that is,…

This paper reports on how participation in a secondary school musical production, within a life skills education programme, may contribute curricularly and pedagogically towards equipping learners for meaningful, successful living in a rapidly transforming society. Using the life skills curriculum for the subject Life Orientation, and employing…

The present case study examines classroom interaction in an English as a second language (ESL) class in an urban high school. The study intends to explore the in-depth nature of teacher's effective teaching practices during the instructional time with focus on their influence on linguistically and culturally diverse English language learners'…

The Concerns-Based Adoption Model (Hall & Hord, 2006) is one tool educational leaders can use to understand the process of change and teachers' stage-related concerns when implementing innovations. This paper presents select findings from a comparative case study of two urban elementary schools in which changes in teachers' reports of their…

An extension to the SIBTEST procedure of R. Shealy and W. Stout (1993) to detect differential item functioning (DIF) is proposed to handle polytomous items. Results of two simulations suggest that the modified SIBTEST performs reasonably well and sometimes can provide better control of impact-induced Type I error inflation. (SLD)

Twenty-two junior-year college students were tested at a college language, speech and hearing clinic. A statistical analysis was performed on their scores on the Woodcock-Johnson Psychoeducational Battery and on oral and written language samples. Results were compared with those of a group of 25 normal college students in their junior year.…

Exact testing was evaluated as a method for conducting Mantel-Haenszel differential item functioning (DIF) analyses with relatively small samples. A series of computer simulations found that the asymptotic Mantel-Haenszel and the exact method yielded very similar results across sample size, levels of DIF, and data sets. (SLD)

This study was a preliminary step in gathering reliable data on suicides and suicide attempts in Padua, Italy. Data were collected from the first aid department of the Padua general hospital, 67 general practitioners in the city, staff of a night-time and holiday home-call medical service, the reanimation department of the Padua general hospital,…
