While elementary teachers encourage students to monitor their own reading and give them strategies to comprehend the text and build their vocabulary, middle school teachers stop modeling and encouraging these strategies but still expect that students are cognizant of metacognition and strategies. As a result, more students are entering college…

The field of language teaching and learning is in dire need of replications of vocabulary and comprehension research with diverse populations of learners. We propose for replication one large-scale vocabulary intervention carried out successfully in a middle-school with monolingual and multilingual students. This study was carried out several…

"Career Academies" is a dropout prevention strategy for youth considered most at risk of dropping out of high school. Students in the program take both career-related and academic courses and acquire work experience through partnerships with local employers. "Career Academies" integrate rigorous academic curricula with career…

Dramatic changes occur in abstract reasoning, physical maturation, familial relationships and risk exposure during adolescence. It is probable that delivery of behavioral interventions addressing decision-making during the preadolescent period and later in adolescence would result in different impacts. We evaluated the intervention effects of an…

This study evaluated an approach to professional development for middle school science teachers by closely examining one grade 8 course that embodies that approach. Using a cluster-randomized experimental design, the study tested the effectiveness of the Making Sense of SCIENCE[TM] professional development course on force and motion (Daehler,…

The purpose of this study was to determine the impact of a school-based, job-embedded professional development program on elementary and middle school teacher efficacy for technology integration. Teacher efficacy has been identified as a strong predictor of whether the content of professional development will transfer to classroom practice…

Given the current emphasis on conducting high-quality experimental studies, it is becoming increasingly important for researchers to accompany their studies with evaluations of the "fidelity of implementation" of the experimental treatments. This article compares the form and extent of an experimental treatment to student learning. The study…

The purpose of this study is to compare the efficacy of three different approaches to professional development in Earth science education: preparing teachers to "adopt" expert-"design" curricula; preparing teachers to use a principled approach to design curricula; and preparing teachers to use a principled approach to "adapt" curricula. The claims…

This study was an investigation of staff development programs designed to provide teachers with strategies through which all learners, including gifted, minority, and limited-English proficient students, can be appropriately served in a middle school environment sensitive to diverse learner academic needs. Participants in the study were assigned…
