As schools continue to focus on outcome-based instructional practices, less emphasis is placed on the creativity and reasoning necessary for students to become effective critical thinkers. As a result, students struggle to demonstrate creative problem-solving skills in the classroom. This study examines how the facilitation of an instructional…

The Japanese lesson study (JLS) model for curriculum development has seen limited application to middle school science classrooms. The JLS model was used to develop and refine three hands-on activities focused on four major eighth grade science topics from the California curriculum. Prior assessments of these topics showed limited understanding by…

Twenty years ago, a major curriculum revision at a large, comprehensive university in the Western United States led to the implementation of an integrated lecture/laboratory (studio) experience for our engineering students taking general chemistry. Based on these twenty years of experience, construction of four purpose-built studio classrooms to…

This article reports an investigation of a professional development program to enhance elementary teachers' ability to engage their students in argument from evidence in science. Using a quasi-experimental approach, three versions were compared: Version A--a 1-week summer institute with a 2-week summer practicum experience and 8 follow-up days…

The increasing use of interactive learning [IL] strategies in Astro 101 classrooms has led some instructors to consider the usefulness of a textbook in such classes. These strategies provide students a learning modality very different from the traditional lecture supplemented by reading a textbook and homework and raise the question of whether the…

This article describes the conversion of a lecture-based molecular biology course into an active learning environment in a studio classroom. Specific assignments and activities are provided as examples. The goal of these activities is to involve students in collaborative learning, teach them how to participate in the learning process, and give…

Can novel 3D models help students develop a deeper understanding of core concepts in molecular biology? We adapted 3D molecular models, developed by scientists, for use in high school science classrooms. The models accurately represent the structural and functional properties of complex DNA and Virus molecules, and provide visual and haptic…

Understanding key concepts in molecular biology requires reasoning about molecular processes that are not directly observable and, as such, presents a challenge to students and teachers. We ask whether novel interactive physical models and activities can help students understand key processes in viral replication. Our 3D tangible models are…

A visual aid teaching tool, the DanceChemistry video series, has been developed to teach fundamental chemistry concepts through dance. These educational videos portray chemical interactions at the molecular level using dancers to represent chemical species. Students reported that the DanceChemistry videos helped them visualize chemistry ideas in a…

This article examines the Mathematics, Engineering, Science Achievement (MESA) program and investigates its impact on underrepresented student populations. MESA was started in California during the 1970s to provide pathways to science, technology, engineering, and mathematics careers for underrepresented students and represents an exemplar model…

Latino/as are an increasingly large subset of the United States population; however, they continue to be underrepresented in science careers. Because of this increase, research regarding Latino/as has improved, but there are still many gaps in regards to gender-specific predictors to pursue science careers. To address this lack of literature, the…

This paper presents findings from a 4-year project that developed and implemented a blended inquiry science and English Language Development (ELD) program in a large urban California school district. The sample included over 2,000 students in Kindergarten through 5th grade. Participating students' English and science achievement was compared to a…

In this article, we examine classroom observations from a 3-year large-scale randomized trial in the Los Angeles Unified School District (LAUSD) to investigate the extent to which a professional development initiative in inquiry science influenced teaching practices in in 4th and 5th grade classrooms in 73 schools. During the course of the study,…

We report the results of a pilot validation study of the Quality Assessment in Science Notebook, a portfolio-like instrument for measuring teacher assessment practices in middle school science classrooms. A statewide sample of 42 teachers collected 2 notebooks during the school year, corresponding to science topics taught in the fall and spring.…

Although studies have documented teachers' growth in assessing science resulting from professional development or science methods courses, little attention has been given to growth while being prepared to assess a linguistically diverse student population. In this study, the growth of 11 secondary science preservice teachers is documented by…
