A modified version of the Task Analysis Guide in Science served as our conceptual framework: It assesses both the integration of practices and content (i.e., the kind of thinking required), and the cognitive demand of tasks (i.e., the level of thinking required) in teachers’ lessons. We used this framework to qualitatively analyze our preservice teacher participants’ edTPA (teacher performance assessment) lessons—including their written commentaries, video-recorded lesson excerpts, and student work samples—for their implementation of the NGSS using mathematics and computational thinking practice. We examined (1) the integration of the mathematical content and practices outlined in the Common Core State Standards for Mathematics within the target NGSS practice, and (2) the cognitive demand of the mathematics in relation to science and mathematical practices. We found that four of our six preservice teachers implemented lessons that were integrated and cognitively demanding: These participants used the mathematics to move students’ understanding of the science phenomena forward. However, the other two participants implemented lessons that integrated mathematical content and practices but were low in cognitive demand. We conclude with implications for how teacher education programs can better support preservice teachers’ implementation of lessons that are both integrated and cognitively demanding so as to promote students’ mathematical reasoning and scientific sensemaking.

Research in Practice: Preparing and Retaining K-12 STEM Teachers in High-Need School Districts

We collected and analyzed survey and interview data from current and former participants of a University of California system-wide STEM teacher recruitment program called CalTeach. We found a significant relationship between undergraduates’ decision to pursue a career in teaching and the number of undergraduate education courses they completed. We also found that undergraduates who decided to pursue a career in teaching reported various ways that CalTeach influenced their decision. Undergraduates reported that participating in CalTeach reinforced or strengthened their decision to pursue teaching and that the classroom-based field experiences were especially helpful in shaping their decision. Indeed, the field experience component of CalTeach provided participants with opportunities to gain experience w...

Our study was situated in a scholarship program that served two groups: undergraduate STEM majors interested in teaching, or potential teachers, and graduate students enrolled in a teacher education program to earn their credentials, or preservice teachers. The two groups completed intensive practicum experiences in STEM-focused academies within two public high schools. We conducted a series of interviews with each participant and used grade-level competencies outlined in the Next Generation Science Standards to analyze their understanding of the practice of developing and using models. We found that potential and preservice teachers understood this practice in ways that both aligned and did not align with the NGSS and that their understandings varied across the two groups and the two practicum contexts. In our implications, we recommend that teacher educators recognize and build from the various ways potential and preservice teachers understand this complex practice to improve its implementation in science classrooms. Further, we recommend that a variety of practicum contexts may help beginning teachers develop a greater breadth of understanding about the practice of developing and using models.

The study examined 18 science faculty members' perceptions in a professional development seminar series and focused on these issues: (1) perceptions of students; (2) use of inclusive curriculum and instruction; and (3) views of the nature of science. Results indicate that family, cultural, and social expectations have effects on the academic achievement of students at the elementary and secondary education levels. Using scientists' experience-based ideas on equity issues to provide more equitable science education for all is recommended. (Contains 76 references.) (YDS)

The idea that students should investigate practical matters of importance to the local community ... more The idea that students should investigate practical matters of importance to the local community is hardly new. Neither is the belief that disciplines should be linked and taught in an integrated fashion. In the 1930s, science textbooks had titles like Everyday Problems in Science. Students learned about soil erosion and conservation methods; about infectious disease, vaccination, and inoculation. In mathematics, they learned about consumer discounts, compound interest, and balancing checkbooks. More than three decades earlier, John Dewey pioneered an educational philosophy of focusing school work on neighborhood problems and drawing from the many disciplines as students engaged in such activities. He pointed out that real-world problems are not readily confined within disciplinary boundaries, and neither should schooling be so confined.

In the 1990s, diSessa (1993) introduced knowledge-in-pieces as an alternative learning theory to conceptual change and termed these small cognitive elements phenomenological primitives (p-prims). Unlike concepts, p-prims are ideas that are not formally learned; that are neither correct nor incorrect themselves, but can be appropriately or inappropriately applied in a given context; and that are activated in concert with other elements. Over time, other researchers then built on diSessa’s work. For example, Hammer (2004) referred to these small cognitive elements as resources and identified resources both for learning physics and for epistemology. Understanding learning as small cognitive pieces that must work together to make sense of phenomena helps to describe the tenaciousness of alternative conceptions in science. It also resonates with the descriptions of learning and teaching put forth in the Next Generation Science Standards (NGSS Lead States, 2013) used in the United States. As such, after outlining the development of knowledge-in-pieces perspectives on learning, we examine the implications that these have for how instruction is designed.

The teacher taught an introductory integrated science course to classes with a large percentage (44%) of students who spoke Spanish as their first language. We investigated the instructional strategies this teacher used to support her ELLs in the practices of argumentation and communication, and the ways ELLs constructed and communicated claims, evidence, and reasons in whole class and small group settings as a result. From qualitative analyses of teacher interviews, classroom interactions, and student products, we found that the teacher routinely implemented three types of instructional supports to help ELL students argue from evidence and communicate information: primary language support (although she herself was not fluent in Spanish), deliberate scaffolds, and small group instruction. Further, given these multiple opportunities for engagement, we found that ELLs experienced both successes and challenges participating in class, crafting arguments from evidence, and reading and producing written texts: While ELL students constructed aspects of arguments in small groups, the substance of their discussions was not necessarily reflected in their whole class participation or written products. Taken together, our findings emphasize the need to more closely attend to the teaching and learning of discourse in science. We end with ways to strengthen both research on and teaching of science for ELLs.

This study implemented a studio day professional development cycle with inservice teachers who worked with multilingual students in Math 1 classrooms. This study examined teachers’ initial perceptions of multilingual learners and their understanding how to prepare for, challenge, and support multilingual learners. Teachers reported that, while their previous learning experiences around multilingual learners and mathematics were limited, this professional development opportunity allowed them to extend beyond simply attending to vocabulary to consider how to access text in rich ways to engage their students in more meaningful learning.

We qualitatively analysed video records of instruction and focussed our analysis on discussions stemming from formative assessments embedded in learning progression-based curricular units. We found that discussions could be placed on a quality continuum from recitation, to emergent, to transitional, to productive based on the degree to which teachers went beyond eliciting student ideas. We also found that discussion quality reflected the type and distribution of discourse moves teachers employed. In the highest quality (or productive) discussions, teachers used a concerted array of discourse moves to elicit, mark, and build on student ideas, including pressing students for reasoning, highlighting similarities and differences among the ideas and reasonings presented, and connecting student id...

Our course embodies three principles: (1) building from students’ funds of knowledge; (2) implementing cognitively demanding tasks; and (3) providing opportunities for rich language and literacy exposure and practice. Our methods and analysis were guided by three research questions: How did preservice science teacher participants understand the three principles of our capstone course? What successes and struggles did they identify when attempting to use these three principles to inform their classroom practice? What suggestions did they have for ways to improve the course? From our qualitative analysis of interviews with preservice science teachers, we found they were better at describing and identifying language rich opportunities for their students than at identifying ways they used their students’ funds of knowledge to inform their instruction. We also found that they felt they would benefit from knowing how to identify the needs of ELLs and how to better differentiate instruction for students. These findings make clear that we can certainly improve this capstone course. Still, our goal remains to foster the development of an adaptive disposition so that preservice science teachers can effectively work with their unique and diverse group of ELLs, not only as student teachers in a temporary placement but also as beginning teachers in their own science classrooms.

The elementary students and undergraduates collaborated in small teams to design and build robots that would dance together. The program was augmented with mentors from the Society of Women Engineers who helped run weekly after school sessions at the elementary school. This program engaged elementary students in engineering design with a collaborative gender-neutral project. Moreover, this program exposed a group of elementary students with a predominantly masculine perception of engineering to female engineer mentors for the first time. By the end of the program, students developed a more comprehensive understanding of engineering and everyone considered engineering as a possible career.

Several barriers exist to meaningful parent education and parent-professional partnerships, which can lead to lower quality outcomes for both the individual with a disability and their families. These barriers should be identified and addressed. This study used a survey measure to gather quantitative and qualitative information on parental perceptions of barriers to behavioral parent education and training as well as suggestions for creating a stronger familyprofessional partnership. Common themes that emerged from the analysis include: a need for open and honest communication, the importance of a professional's training and experience in the field, and the availability of services. Knowledge of the barriers which exist in behavior parent training will allow providers to better serve families and ensure a stronger outcome of service. Implications for both research and practice are discussed.
