The current study employed the content analysis approach to investigate the multiple mathematical representations and transitions among them in 8th Grade Mathematics Textbook. An observation method was used to analyses the teacher practices (n=35 observations), and record the representations and transitions. The results showed that there was an existence of symbol and verbal representations in the textbook and teachers’ implementation. Meanwhile, the other three representations (pictures and figures, models and Cutters, and life situations) and the transactions between them were at low rates in the textbook and teachers’ implementation.

eric.ed.gov har udgivet: To address the problem of low achieving math students, a cross-age math tutoring intervention paired middle school tutors with kindergarten and first grade students with low math skills. This instrumental group case study explored the effects of the intervention on the math skills of the students through teacher interviews and the testing program of “Aimsweb Plus” (Pearson, 2017) before and after the tutoring intervention. Most of the teachers of the tutees reported measurable math gains possibly from the tutoring and most of the teachers observed improved attitude towards math work for the young tutees. Most teachers of the tutors did not report any measurable math gain from tutoring young students. All the teachers of the tutors recommended the cross-age tutoring experience as the middle school students seemed… Continue Reading →

eric.ed.gov har udgivet: Historically, students took Algebra I in high school, but there has been a recent trend toward taking it in middle school (Domina, 2014). In the past two decades the proportion of middle school students taking Algebra I or more-advanced math courses has doubled (Domina, 2014). Success in Algebra I is important because it is a gateway course for advanced math (Star et al., 2015). Students who take and pass Algebra I are more likely to take and pass more-advanced math courses in high school (Snipes & Finkelstein, 2015). This trend has created a need for middle school teachers with more-advanced knowledge of math content, because prior research has suggested that teachers’ knowledge of math content plays an important role in student achievement (National Mathematics Advisory Panel, 2008).… Continue Reading →
