The authors evaluated the effects of P-SELL, a science curricular and professional development intervention for fifth-grade students with a focus on English language learners (ELLs). Using a randomized controlled trial design with 33 treatment and 33 control schools across three school districts in one state, we found significant and meaningfully sized intervention effects on a researcher-developed science assessment and the state science assessment. Subgroup analyses revealed that the P-SELL intervention had a positive and significant effect for each language proficiency group (ELLs, recently reclassified ELLs, former ELLs, and non-ELLs) on the researcher-developed assessment. The intervention also had a positive effect for former ELLs and non-ELLs on the state science assessment, but for ELLs and recently reclassified ELLs, the effect was not statistically significant.

As secondary students' interest in science is decreasing, schools are faced with the challenging task of providing adequate instruction to engage students-and more particularly the disadvantaged students-to learn science and improve their science inquiry skills. In this respect, the integration of Web-based collaborative inquiry can be seen as a possible answer. However, the differential effects of Web-based inquiry on disadvantaged students have barely been studied. To bridge this gap, this study deals with the implementation of a Web-based inquiry project in 19 secondary classes and focuses specifically on gender, achievement level, and academic track. Multilevel analysis was applied to uncover the effects on knowledge acquisition, inquiry skills, and interest in science. The study provides quantitative evidence not only that a Web-based collaborative inquiry project is an effective approach for science learning, but that this approach can also offer advantages for students who are not typically successful in science or who are not enrolled in a science track. This approach can contribute to narrowing the gap between boys and girls in science and can give low-achieving students and general-track students an opportunity to develop confidence and skills for learning science, bringing them to a performance level that is closer to that of high-achieving students.

Invention and Productive Failure activities ask students to generate methods that capture the important properties of some given data (e.g., uncertainty) before being taught the expert solution. Invention and Productive Failure activities are a class of scientific inquiry activities in that students create, implement, and evaluate mathematical models based on data. Yet, lacking sufficient inquiry skills, students often do not actualize the full potential of these activities. We identified key invention strategies in which students often fail to engage: exploratory analysis, peer interaction, self-explanation, and evaluation. A classroom study with 134 students evaluated the effect of supporting these skills on the quality and outcomes of the invention process. Students in the Unguided Invention condition received conventional Invention Activities; students in the Guided Invention condition received complementary metacognitive scaffolding. Students were asked to invent methods for calculating uncertainties in best-fitting lines. Guided Invention students invented methods that included more conceptual features and ranked the given datasets more accurately, although the quality of their mathematical expressions was not improved. At the process level, Guided Invention students revised their methods more frequently and had more and better instances of unprompted self-explanations even on components of the activity that were not supported by the metacognitive scaffolding. Classroom observations are used to demonstrate the effect of the scaffolding on students' learning behaviours. These results suggest that process guidance in the form of metacognitive scaffolding augments the inherent benefits of Invention Activities and can lead to gains at both domain and inquiry levels.

What does it mean for ethnic minority girls, who have historically been marginalized by schools, to \"see themselves\" in science? Schools fail to create spaces for students to engage their identity resources in the learning of science or to negotiate and enact new science-related identities. This study investigates relationships among identity, engagement, and science discourse and provides a conceptual argument for how and why underserved ethnic minority girls engage in collective identity work, with science learning as a valued byproduct. The primary context for the study was Lunchtime Science, a 4-week lunchtime intervention for girls failing their science courses. There were 4 distinct ways the girls engaged in learning during Lunchtime Science: gleaning content for outside worlds, supporting the group, negotiating stories across worlds, and critiquing science. Each pattern had a signature profile with variations in the sociohistorical narratives used as resources, the positioning of one another as competent learners, and the type of science story critiqued and constructed. These findings indicate that when the girls were given opportunities to engage their personal narratives, and when science was open to critique, ethnic minority girls leveraged common historical narratives to build science narratives. Moreover, the girls' identity work problematizes the commonplace instructional notion of \"bridging\" students' everyday stories with science stories, which often privileges the science story and the composing of \"science\" identities. It also challenges researchers to investigate how the construction of narratives is broader than 1 community of practice, broader than 1 individual, and broader than 1 generation.

This study investigated the extent to which a state-funded teacher professional development program designed to improve K–2 science education led to changes that persisted beyond the funding period. The study used a longitudinal, mixed-methods approach and examined persistence of changes in teachers’ content knowledge, self-efficacy, instructional time, and instructional practices in science. It also examined the extent to which school contexts and resources provided ongoing support for teachers to implement what they learned in the professional development. Data sources, collected over a 5-year period, included a teacher survey, a self-efficacy assessment, content knowledge tests, interviews, and classroom observations. Findings indicated a beginning pattern of decline during the 2 years after the program ended, but outcomes remained higher than before the professional development. Contextual factors varied widely across schools and influenced, in particular, the amount of time teachers devoted to science and their decisions about instructional strategies.

Formative assessment has been demonstrated to result in increased student achievement across a variety of educational contexts. When using formative assessment strategies, teachers engage students in instructional tasks that allow the teacher to uncover levels of student understanding so that the teacher may change instruction accordingly. Tools that support the implementation of formative assessment strategies are therefore likely to enhance student achievement. Connected classroom technologies (CCTs) include a family of devices that show promise in facilitating formative assessment. By promoting the use of interactive student tasks and providing both teachers and students with rapid and accurate data on student learning, CCT can provide teachers with necessary evidence for making instructional decisions about subsequent lessons. In this study, the experiences of four middle and high school science teachers in their first year of implementing the TI-Navigator ™ system, a specific type of CCT, are used to characterize the ways in which CCT supports the goals of effective formative assessment. We present excerpts of participant interviews to demonstrate the alignment of CCT with several main phases of the formative assessment process. CCT was found to support implementation of a variety of instructional tasks that generate evidence of student learning for the teacher. The rapid aggregation and display of student learning evidence provided teachers with robust data on which to base subsequent instructional decisions.

At High Tech Elementary Chula Vista in California, teachers are using improvement science, a method for solving a problem of practice with disciplined inquiry, to help students make their thinking visible. The teachers wanted to increase students’ use of how and why language to articulate their thinking; to that end, they’ve been using short cycles of inquiry, action, and reflection to test different change ideas. The teachers found that improvement science fosters reflective practice, helps teachers take action, and facilitates collaboration and sharing.

This study examined the teachers' development as scientists for participants in three National Science Foundation Research Experiences for Teachers. Participants included secondary science and math teachers with varying levels of education and experience who were immersed in research environments related to engineering and science topics. Teachers' functionality as scientists was assessed in terms of independence, focus, relationships with mentors, structure, and ability to create new concepts. Hierarchies developed within these constructs allowed tracking of changes in functionality throughout the 6-week programs. Themes were further identified in teachers' weekly journal entries and exit interviews through inductive coding. Increases in functionality as scientists were observed for all teachers who completed both the program and exit interview (n = 27). Seven of the 27 teachers reached high science functionality; however, three of the teachers did not reach high functionality in any of the constructs during the program. No differences were observed in demographics or teaching experience between those who did and did not reach high functionality levels. Inductive coding revealed themes such as teachers' interactions with mentors and connections made between research and teaching, which allowed for descriptions of experiences for teachers at high and low levels of functionality. Teachers at high functionality levels adjusted to open-ended environments, transitioned from a guided experience to freedom, felt useful in the laboratory, and were self-motivated. In contrast, teachers at low functionality levels did not have a true research project, primarily focused on teaching aspects of the program, and did not display a transition of responsibilities.

A randomized controlled trial conducted in Alaska examined the efficacy of 2 second-grade modules of the reform-oriented and culturally based Math in a Cultural Context (MCC) teacher training and curriculum. The results show that thePicking Berries(representing and measuring) andGoing to Egg Island(grouping and place value) modules significantly improved students' mathematics performance. The analysis also revealed that the impacts were broad based and significant for most of the subgroups of schools and students examined.

Angela Chapman and Allan Feldman ( 2016 ) conducted a study that aimed to exam how a group of diverse urban high school students were affected by the participation in a contextually based authentic science experience. The analysis of all data led the authors to conclude that the experience of authentic science positively influenced the science identity of students and promoted a shift in perceptions from stereotypical to more diverse views of scientists. For the purpose of this forum paper, we concentrated on the unexpected results of Hispanic students in the IAS instrument. In the authors’ interpretation, Hispanic students were classified as non science identities because they do not feel recognized as a particular kind of student in that school, being possibly more marginalized than other students. We tried to expand the discussion bringing the contribution of a sociocultural approach of science construction and of science identity to enrich some of the issues involved. Our concise analysis does not allow conclusions about the Hispanic students’ results, but we believe it helped to understand sociocultural problems involved in their science identity and to reveal the inequality in science production as one of these problems.
