although there have been changes made to ontario's mathematics curriculum within the last decade to ensure student success, a significant number of 世界杯2022赛程表淘汰赛 in ontario schools have been achieving at or below a level 1 and labeled 'at-risk' by the ministry of education's at-risk working group (expert panel on student success in ontario, 2004). this study explores intermediate 世界杯2022赛程表淘汰赛 in a northern ontario city who are at-risk in mathematics. the purpose of the study is to investigate the various factors that inhibit student success in mathematics and to determine what 世界杯2022赛程表淘汰赛 need in order to succeed. since teachers are in a position to enhance and facilitate student success, the roles of teachers as well as student attitudes and dispositions in mathematics classrooms need clarification.the central questions guiding this study are: what types of strategies and practices do mathematics teachers use in their classrooms for all 世界杯2022赛程表淘汰赛 and for those who they believe to be at-risk in mathematics? what are the observable behaviors of the 世界杯2022赛程表淘汰赛 identified as at-risk as they interact in the classroom environment? what personal and mathematics-related learning characteristics can be observed in the at-risk 世界杯2022赛程表淘汰赛 ? the data collection process involved a collective case study of six 世界杯2022赛程表淘汰赛 and three teachers, who were studied to provide an in-depth understanding of how mathematics teachers and their 世界杯2022赛程表淘汰赛 interacted in mathematics classrooms. the data was mainly collected through participant observation, student work records and discussions with 世界杯2022赛程表淘汰赛 and teachers.the findings indicate that the 世界杯2022赛程表淘汰赛 in this study appear to be inhibited by many personal and behavioral issues. some have been impacted by multiple school transfers and some have poor attendance. most expressed a lack of confidence in their ability to succeed in mathematics, and some have a negative attitude toward the subject matter. each student case is unique as their individuality and experiences play a role in their beliefs, attitude toward the subject matter, and desire to achieve. this study also consistently showed that the teachers tended to fall back on traditional practices when working with 世界杯2022赛程表淘汰赛 at-risk in mathematics, and seemed particularly reluctant to adopt reform-based teaching methodologies with these 世界杯2022赛程表淘汰赛 .
