The "Building a System of Tens Casebook" was developed as the key resource for participants' Developing Mathematical Ideas seminar experience. The thirty cases, written by teachers describing real situations and actual student thinking in their classrooms, provide the basis of each session's investigation of specific mathematical…

This case study details how one leader worked to support a fifth-grade student's gender transition midway through a school year. Despite a conservative political environment, push-back from families and community members, and district controversy surrounding adoption of a Transgender Inclusion policy, the principal worked closely with the student,…

The study aimed to extend current research on conditions that better support analogical encoding through mutual alignment. We focused on two variables that have not been examined independently in previous studies: the joint presentations of two cases of a scientific phenomenon and the explicit instructions for comparison. One hundred and…

In this Voices Inside Schools essay, Dr. Pat Clifford and Susan Marinucci take us inside a classroom engaged in "genuine inquiry." As we follow Russell and his fellow fifth-grade scientists through their exploration of desalination, we witness the evolving nature of questioning, learning, and understanding in spaces of inquiry. The authors offer…

Engaging students in worthwhile learning requires more than a knowledge of underlying principles of good teaching. It demands considerable practice as well as images of what good teaching in particular situations and for particular purposes might look like. This volume provides these images. These cases were written from authentic, unrehearsed…

Students get excited about science when they investigate real scientific problems in the classroom, especially when the investigation extends over several weeks. This article describes a health-science problem-based learning (PBL) investigation that a group of teachers and teacher educators devised together for a group of fourth- to sixth-grade…

This study addresses preservice teachers' perceptions toward online experiences, specifically, their perceptions about utilizing an online science methods curriculum versus a traditional methods curriculum. Thirty-eight senior level preservice teachers at a midwestern U.S. university completed surveys about their experiences during their methods…

The main purpose of this study was to investigate the effects of a case study approach on students' achievement and attitudes towards viruses, bacteria, fungi, and protista. Fifth-grade students (N = 88) from two different classes were involved in the study. One intact class was assigned as the experimental group, whereas the other intact class…

An evaluation mosaic brings together different methods and forms to present an overall picture of the impact this professional learning experience had on teachers' practices and on student achievement. Using this framework, professional developers were able to determine whether they were getting the results they wanted--and they did.
