Blended learning, which combines face-to-face workshops with self-directed online learning, is becoming a good alternative in designing and deploying professional development programs. The online component adapts to teachers' time constraints, requires fewer trained professionals for its implementation, and enhances participants' opportunities to…

Research indicates that a large percentage of students have misconceptions of the equal sign and that this can be detrimental to their mathematical pursuits as they progress through algebra. In order for students to develop a strong understanding of the meaning of the equal sign, algebra teachers must be aware of the viewpoints their students will…

While qualitative research has shown great benefits for teachers who receive coaching, there is a paucity of experimental research examining students' academic outcomes after their teachers received ongoing support from a knowledgeable and experienced coach. Thus, a quasi-experimental design investigated the literacy outcomes of 452 students…

This study investigated the impact of a summer institute with follow-up coaching (treatment) versus no professional development (control) on middle and high school teacher and student science practice outcomes. Treatment teachers participated in a 2-week summer institute that used evidence-based professional development practices followed by…

China boasts one of the largest adolescent populations in the world, with 165 million in total (United Nations, 2017). In recent decades, Chinese adolescents have reached sexual maturity at increasingly early ages, and more and more young people in China are open to premarital sex while at the same time they general lack sexual and reproductive…

The purpose of this article is to report on an investigation of the perceptions and performance of mathematics teachers in a teacher professional learning (TPL) programme based on realistic mathematics education (RME) principles, which included a topic on transformations, undertaken by the researcher. Forty-seven Senior Phase (Grade 7--9) teachers…

We posit that professional development (PD) models fall on a continuum from highly adaptive to highly specified, and that these constructs provide a productive way to characterize and distinguish among models. The study reported here examines the impact of an adaptive mathematics PD model on teachers' knowledge and instructional practices as well…

The authors drew upon Remillard and Bryans' categorization of curriculum use in observating two middle-grade teachers' integration of Standards-based curriculum materials produced by the National Council of Teachers of Mathematics. Each teacher participated in a two-year professional development program focused on increasing content knowledge and…

Growing interest in teaching quality and accountability has focused attention on the need for rigorous studies and evaluations of professional development (PD) programs. However, the study of PD has been hampered by a lack of suitable instruments. The authors present data from the Teacher Knowledge Assessment System (TKAS), which was designed to…

This article reports on two studies using "Language Muse[superscript SM]" (LM), a web-based, teacher professional development (TPD) application designed to enhance teachers' linguistic awareness and to support teachers in the development of language-based instructional scaffolding for English language learners (ELL). In Study 1,…

The two research questions that guided this study were: (1) How do preservice teachers develop mathematical knowledge for teaching during a coordinated math methods course and field experience? and (2) What types of portfolio tasks lend themselves to documenting mathematical knowledge in teaching? Six, female, elementary (K-8) teacher candidates…

We investigated the extent to which a seven-week action research mentoring project would help two junior high school science teachers to feel more confident and successful in their abilities to use accommodation strategies to support the English language learners (ELLs) in their classes, and consequently to increase their ability to assess more…

This study explored how mathematics content and methods courses for preservice elementary and middle school teachers could be improved through the integration of a set of instructional materials based on the National Assessment of Educational Progress (NAEP). A set of eight instructional modules was developed and tested. The study involved 7…

To add to the evidence base on effective strategies for teaching English language learner students, the 2006-2011 REL West at WestEd conducted a rigorous study, using an intent-to-treat model, of the impact on middle grades student achievement of offering teachers the opportunity to participate in a teacher professional development program. The…

An alternative mathematics preparation program for K-8 teachers is described as an existence proof that steadily increasing effectiveness of STEM (science, technology, engineering, and mathematics) preparation is possible. The program is based on treating every lesson in each of five mathematics content and methods courses as objects of study.…
