The purpose of this study was to investigate implementation of an early intervention mastery activity during the first two weeks of college algebra and precalculus courses at a large U.S. public university. Statistical modeling of (N = 935) students’ performance in the courses, including a logistic regression model of pass/fail course achievement w...

Research-based guidelines for learning variation exist (e.g., Franklin et al., 2007; Garfield, delMas, & Chance, 2007), but little is known about how teachers plan to teach standard deviation, or how these plans align with recent recommendations. In this article, we survey lesson plans designed by inservice and preservice secondary mathematical tea...
Article
This manuscript presents findings from a study about the knowledge for and planned teaching of standard deviation. We investigate how understanding variance as an unbiased (inferential) estimator – not just a descriptive statistic for the variation (spread) in data – is related to teachers’ instruction regarding standard deviation, particularly aro...
Article
In this paper, we present findings from a preliminary analysis of transcript data in the High School Longitudinal Study (HSLS:09), a large-scale longitudinal investigation of academic achievement among U.S. high school students. Using proportional flow diagrams of course-taking patterns, we illustrate differences in calculus completion associated w...
Presentation
Studies exploring the role and impact on teaching of secondary teachers' knowledge of the mathematical horizon will be presented; topics include CCSSM, abstract algebra, real analysis, and statistics. Illustrations connected to classroom teaching practices will be examined and implications for mathematics teacher education discussed.

At the University of Nebraska-Lincoln, nearly 1000 students sign up for one of College Algebra, or College Algebra and Trigonometry every fall. Of these students, more than 75% are first time freshman. Finding ways to motivate and encourage these students together with early identification strategy for struggling students is critical to success not...

... Asimismo, las metodologías de investigación se clasificaron de acuerdo con el tipo de análisis de la información realizado en cada documento. Una parte de los documentos utilizó, como medio para apoyar sus conclusiones, técnicas de análisis cuantitativo, como regresión lineal múltiple, ANOVAS, modelos jerárquicos, validación de escalas o análisis descriptivos (Brisbin y Maranhao, 2019;Huey et al., 2018;Kulkarni et al., 2019;Nielsen y Kreiner, 2018); o bien técnicas cualitativas, como el estudio de casos, la codificación axial, análisis de discurso y entrevistas a profundidad (Moreira y Samá, 2014;Sánchez y Gómez, 2015;Strayer et al., 2019). Sin embargo, una considerable cantidad de artículos ejecutan propuestas didácticas mediante actividades de aula, o bien, plantean propuestas para ser adaptadas a diferentes contextos, en las cuales destacan: aprendizaje basado en proyectos y desarrollo de aplicaciones para comprender conceptos estadísticos (Brown, 2019;Liu, 2017;Rodríguez y Sánchez, 2016;Ruggieri, 2019). ...

... Formula untuk perhitungan root mean square error (RMSE) dapat ditunjukkan pada persamaan (1), (Li et al., 2015): Selain perhitungan root mean square error (RMSE), perkiraan nilai parameter standar deviasi juga penting dalam menentukan standar akurasi dari pekerjaan yang telah dilakukan dengan definisi sebagai nilai statistik dalam menentukan persebaran data dalam sampel, serta pendekatan titik data individu ke rata-rata nilai sampel (Hidayat et al., 2019). Standar deviasi dapat dilakukan perhitungan dengan menggunakan persamaan seperti dibawah ini (Wasserman et al., 2017): ...
... Stevenson et al. (1994) note that the sequential nature of mathematics significantly impacts students' opportunities to learn. If students begin high school in Geometry rather than Algebra 1, they have a greater chance of progressing further along the mathematics course sequence and subsequently experiencing greater mathematics success (Champion & Mesa, 2018). Keeping students on-schedule within this accepted mathematics course sequence is crucial to both student mathematics achievement in high school as well as student success in STEM-related studies in higher education (Finkelstein et al., 2012). ...
