The use of data to explain natural phenomena has been a core feature of science education, and science educators continue to call for an increased emphasis on teaching data practices. This mixed methods design-based research study adds to the growing body of research on data practices in science by explaining the learning trends of science teachers involved in a three-year collaborative professional development (PD) using computational thinking (CT) and self-regulated learning (SRL) as a means to support teachers in implementing data practices. The PD resulted in long-term high-quality teacher learning outcomes for all three elements of the PD (data practices, CT, and SRL) despite the upheaval of teaching platforms due to the COVID-19 pandemic. Since the teachers were involved in design-based research, their professional learning focused on collaboratively creating an electronic, interactive notebook with lessons for use in science classrooms across the United States. Creating a common product as an outcome of the PD may have served as motivation for teachers to learn about and implement more data practices, CT, and SRL, which suggests that design-based research is another valuable design for teacher PD.

Individual-based models (IBMs) are increasingly used in marine conservation research, making this is an ideal time to assess IBM use in marine policy. IBMs can contribute important information to marine management and policy questions, as they offer complex methods of understanding ecosystems and animal behaviour, by allowing for heterogeneity in both individuals and environments. A review of 108 international peer-review publications utilizing marine IBMs was conducted using Web of Science (WoS). It was determined that 55% of the WoS articles claimed that the IBMs were relevant or important to marine conservation policy or management. A relevant English-language policy document was located for 83% of the IBMs, but only 32% were cited, while 85% of the same policy documents cited a different, non-IBM, modelling method. A separate survey of 175 policy documents from the Government of Canada was conducted. Of the 60 that contained citations, zero documents cited an IBM, while 75% cited a different modelling method. Of 407 webpages reviewed from the National Oceanic and Atmospheric Administration, the New Zealand Department of Conservation, and the UK Government website, only 4% referenced IBMs. This research demonstrates that, despite claims of usefulness by researchers, IBMs are not used to inform policy, while other model methods are commonly cited. Modellers should not assume that their model will inherently be useful for policy and should instead ensure that they are: 1) addressing a policy need; and 2) making the information accessible to policymakers by crafting a communication plan and/or joining a relevant boundary organization.

In an effort to deepen learning in K-12 science classrooms, there has been a national movement to integrate computational thinking (CT). The purpose of this phenomenographic study was to understand teachers' perceptions of the function and usefulness of a task analysis and a decision tree tool designed to help them with integration. Teachers participated in a long-term professional development to improve their knowledge and application of CT and then developed lesson plans integrating CT into science investigations. To assist in the integration, teachers used the two unique tools. No one lesson plan or content area addressed all of the CT practices, but all CT practices were addressed in lessons across all four science areas. All 19 teachers found that the task analysis tool helped them to shift their lessons to a student-centered focus and helped them pinpoint data practices so they could systematically integrate CT practices. However, they expressed confusion over the amount of detail to document on the tool. Similarly, teachers found both benefits and barriers to the decision tree tool. Teachers found the decision tree tool to be useful in predicting the ways students may misunderstand a data practice and in reflecting on the level of accomplishment of students. However, teachers were sometimes uncertain with how to efficiently document complex student behaviors when engaged with data practices and CT. Implications for the use of the two lesson planning tools is discussed. [ABSTRACT FROM AUTHOR]

A key process in the discipline of science is argumentation, which has recently been receiving more attention in K-12 classrooms. The purpose of this multiple case study was to concurrently examine self-regulated learning processes (SRL) and learning outcomes of three teachers in a professional development (PD) on argumentation in science to assess the relationship between types of learning processes employed by teachers and corresponding learning outcomes. Three teacher cases were selected based on variations in their self-efficacy for the PD, the type of schools in which they taught, and their experiences with argumentation in science. Teachers who were able to use SRL strategies had deeper learning outcomes and created lesson plans that engaged students in higher levels of argumentation. It was found that the SRL microanalysis was useful in eliciting learning processes for learners and provided opportunities for learners to be more aware of their SRL practices. Implications for this study include ways to measure learning processes and learning outcomes concurrently to provide more effective PD instruction. [ABSTRACT FROM AUTHOR]

Student engagement is important for teachers and researchers because it is associated with student achievement. Guided by self-determination theory, this year-long case study used observations and interviews to examine six students’ behavioral, affective, and cognitive engagement in integrated literacy and social studies tasks. Task differences were rated according to the degree to which tasks were authentic, collaborative, challenging, student directed, and sustained. Results demonstrated that, overall, students were more engaged in tasks that include a higher degree of these elements. In particular, students reported that they were engaged in tasks that included collaboration, new learning, and teacher support. [ABSTRACT FROM AUTHOR]

This study investigated the effects of a 1-year professional development (PD) based on a cognitive apprenticeship model of research experiences on inservice teacher self-efficacy of science teaching, motivation, knowledge calibration, and perceptions of inquiry of 19 secondary earth science and biology teachers. The PD facilitator, who serves a dual role as a scientist and teacher educator, utilized a cognitive apprenticeship model to shape both scientific thinking and inquiry instruction with 19 inservice teachers. Results indicated that inservice teachers changed their perceptions of inquiry and maintained high self-efficacy throughout all phases of the study. However, teachers refrained from making long-term changes in their cognitive strategy instruction. Implications provide a fuller picture of teacher learning during a RET program, supported with inquiry instruction and the implications of cognitive apprenticeships in offering authentic science research experiences with minimal laboratory resources.

Surveys have found that weathercaster views on climate change are diverse, with a large majority agreeing that climate change is happening but most remaining unconvinced that human activities are the principal cause. We hypothesized that these differences in climate change views could have implications for weathercasters acting as informal climate change educators, as well as for professional development training for weathercasters attempting to serve such roles. We asked weathercasters at a professional society meeting to provide brief statements on climate change and their roles to educate viewers about climate. We then pooled these statements for an online card-sort activity completed by 29 weathercasters and used network analysis to study the epistemologies of groups according to climate change attitudes. Despite different views on climate change, all weathercasters had a shared ethos for developing their climate change views through consulting observational data and multiple sources of information. Additionally, all weathercasters shared the concern that informal climate education focus on "the science and only the science." Looking specifically at factual statements on climate change, all weathercasters classified the statement, "Climate is always changing," as significant for informal climate education. However, there were differences in how weathercasters perceived the importance of changes in the atmospheric concentration of CO2 and how it relates to human activities. The implications of these findings are twofold. First, without interventions to empower all weathercasters as science communicators, the community may split into communicators explaining the contributions of human activities to climate change versus those who question it. Second, professional societies can play important roles to confront this schism through forums that address conflict, the science-policy interface, and scientific discussions around climate. By appealing to values and codes of conduct shared by all weathercasters, professional development activities can help them build confidence in making public statements about climate change as well as to develop appropriate conceptual scaffolding for relationships between human activities, greenhouse gas emissions, global warming, and climate change.

An understanding of the scientific enterprise is useful because citizens need to make systematic, rational decisions about projects involving scientific endeavors and technology, and a clearer understanding of scientific epistemology is beneficial because it could encourage more public engagement with science. The purpose of this study was to capture beliefs for three groups, scientists, secondary science teachers, and eighth-grade science students, about the ways scientific knowledge is generated and validated. Open-ended questions were framed by formal scientific epistemology and dimensions of epistemology recognized in the field of educational psychology. The resulting statements were placed in a card sort and mapped in a network analysis to communicate interconnections among ideas. Maps analyzed with multidimensional scaling revealed robust connections among students and scientists but not among teachers. Student and teacher maps illustrated the strongest connections among ideas about experiments while scientist maps present more descriptive and well-rounded ideas about the scientific enterprise. The students' map was robust in terms of numbers of ideas, but were lacking in a hierarchical organization of ideas. The teachers' map displayed an alignment with the learning standards of the state, but not a broader view of science. The scientists map displayed a hierarchy of ideas with elaboration of equally valued statements connected to several foundational statements. Network analysis can be helpful in forwarding the study of views of the nature of science because of the technique's ability to capture verbatim statements from participants and to display the strength of connections among the statements.

This study examined the beliefs and rationale pre-service elementary teachers used to choose activities for upper-elementary students in a 1-week intensive science camp. Six undergraduate elementary pre-service teachers were observed as they took a semester-long science methods class that culminated in a 1-week science camp. This qualitative, phenomenological study found that counselors chose activities with the possibility of fun being a priority rather than teaching content, even after they were confronted with campers who demanded more content. Additionally, all six of the counselors agreed that activities involving variable manipulation were the most successful, even though content knowledge was not required to complete the activities. The counselors felt the variable manipulation activities were successful because students were constructing products and therefore getting to the end of the activity. Implications include building an awareness of the complexity of self-efficacy of science teaching and outcome expectancy to improve teacher education programs. [ABSTRACT FROM AUTHOR]
