Articulating the rules, roles, and values that are expected of undergraduate researchers is important as we strive to create a more accessible path into the scientific community. Rules refer to skills required of scientists, roles refer to behaviors consistent with the expectations of a scientist, and values refer to beliefs of the scientific community. Doctoral student mentors have great potential to serve as agents of influence for undergraduate researchers as undergraduates engage in the process of learning to be a scientist through legitimate peripheral participation. As such, we argue that doctoral students are partially responsible for identifying and promoting the rules, roles, and values that undergraduate researchers develop in scientific research. However, few studies have examined what rules, roles, and values are appreciated, or perceived as desirable, by doctoral students and thus expected of undergraduate research mentees. To address this gap, we surveyed 835 life sciences doctoral students who had mentored or would eventually mentor undergraduate researchers. We assessed what qualities and beliefs they appreciate in undergraduate researchers and what advice they would give to undergraduates to maximize their experiences in research. We analyzed their open-ended responses using inductive coding and identified specific rules (e.g., effectively communicate), roles (e.g., demonstrate a strong work ethic), and values (e.g., be driven by intrinsic passion) that doctoral students wrote about. We used logistic regression to determine whether demographics predicted differences among doctoral student responses. We found that gender, race/ethnicity, and college generation status predicted what rules, roles, and values doctoral students appreciated and advised undergraduates to adopt. This research illuminates what rules, roles, and values undergraduate researchers are expected to uphold and identifies relationships between mentor identities and the advice they pass on to students.

National governments are concerned about the disconnection of young people from science, which hampers the development of a scientifically literate society promoting sustainable development, wellbeing, equity, and a green economy. Introduced in 2015 alongside Agenda 2030, the “open schooling” approach aims at enhancing students' science connections through real-life problem solving with families and scientists, necessitating solid evidence for scalability and sustainability. This study conceptualizes “science connection,” a term yet underexplored, as the integration of science's meaning and purpose into personal, social, and global actions informed by socioscientific thinking. It details a novel 32-item self-report questionnaire developed and validated from insights of 85 teachers into “science connection”-enhanced learning. A new consensual qualitative analysis method with visual and textual snapshots enabled developing quantitative measures from the qualitative findings with rigor. The multilanguage instrument provided just-in-time actionable data, enhancing the immediacy and applicability of the feedback to 2082 underserved students aged 11–18 across five countries participating in open schooling activities using the CARE-KNOW-DO model. This innovative feature supports open science and responsible open research, offering real-time insights and fostering immediate educational impact. Exploratory and confirmatory factor analyses revealed five components of science connection: Confidence and aspiration in science; Fun participatory science with teachers, family, and experts; Active learning approaches; Involvement in-and-outside school science activities; and Valuing science's role to life-and-society. Many students felt connected to science— Brazil: 80%, Spain: 79%, Romania: 73%, Greece: 70%, UK: 57%— with boys: 75%, girls: 73%, nonbinary students: 56%. These differences need in-depth research. Results suggest that science connections decline from the primary to secondary education, but the CARE-KNOW-DO model may reengage older students. A robust science connection enhances scientific literacy and builds science capital. This instrument aids policymakers, educators, and learners in identifying factors that facilitate or impede students' engagement with science for sustainable development efforts.

The purpose of this article is to introduce a methodology for analyzing the complex configurations emerging in students' speech and drawing activities, having consequences for how and what students learn and make meaning of in science. Accordingly, we launch a methodology to unfold the multidimensional communication as to deepen the analysis of the science epistemic discourse. We present an empirical account of students' explorations through different signs to demonstrate the construction of the methodology step-by-step. This methodology, a “seven-concept-assemblage,” is rooted in Dewey's pragmatism and Deleuze's experimentalism broadening teachers' and researchers' possibility to target students' science explorations and meaning-making crosscutting different domains. The methodology diminishes the risk of interpretation when grasping unspoken messages and meanings. Empirical data were collected in an elementary school exemplifying the methodology and consist of audio recordings, photographs, fieldnotes, and students' drawings. The result reveals that the methodology in use exposed what and how students explored and learned cognitively and aesthetically. Imagination fertilized the process throughout. Learning then is suggested as a transductive meaning-making process shaped through oral and pictorial relations—always from a purpose.

For students who face marginalization in a discipline, counterspaces are safe spaces of refuge that allow them to express their multiple identities and foster their sense of belonging. While prior qualitative work on counterspaces has highlighted how and why these spaces support marginalized students, there is little quantitative work that provides systemic evidence on broad counterspace initiatives formed to support students' disciplinary sense of belonging. In physics, a discipline that is deeply androcentric, two potential counterspaces have emerged for undergraduate women: the Conferences for Undergraduate Women in Physics (CUWiP) and Women in Physics Groups (WiPG). Drawing on survey data collected from undergraduate women in physics programs across the country who were registering for the 2018 CUWiP (N = 1388), we used structural equation modeling to test the effect of earlier participation in CUWiP and WiPG on students' current sense of belonging and interest in physics. We also tested the mediating effect of believing that there are serious gender issues in physics since these spaces have been found to increase students' consciousness of gender bias. The results revealed a significant positive direct effect of CUWiP and WiPG on sense of belonging. A more complex story emerged for indirect effects where believing in serious gender issues can negatively affect sense of belonging if interest in physics is not positively reinforced. Overall, the findings clearly provide quantitative evidence that broad diversity conference and affinity group initiatives, such as CUWiP and WiPG, can act as counterspaces that bolster belonging for women in disciplines like physics where they are marginalized. However, activities in these spaces should also continue to foster students' unique disciplinary interests.

One reason for the widespread use of the energy concept across the sciences is that energy analysis can be used to interpret the behavior of systems even if one does not know the particular mechanisms that underlie the observed behavior. By providing an approach to interpreting unfamiliar phenomena, energy provides a lens on phenomena that can set the stage for deeper learning about how and why phenomena occur. However, not all energy ideas are equally productive in setting the stage for new learning. In particular, researchers have debated the value of teaching students to interpret phenomena in terms of energy forms and transformations. In this study, we investigated how two different approaches to middle school energy instruction—one emphasizing energy transformations between forms and one emphasizing energy transfers between systems—prepared students to use their existing energy knowledge to engage in new learning about a novel energy-related phenomenon. To do this, we designed a new assessment instrument to elicit student initial ideas about the phenomenon and to compare how effectively students from each approach learned from authentic learning resources. Our results indicate that students who learned to interpret phenomenon in terms of energy transfers between systems learned more effectively from available learning resources than did students who learned to interpret phenomena in terms of energy forms and transformations. This study informs the design of introductory energy instruction and approaches for assessing how students existing knowledge guides new learning about phenomena.

This study examines the often-heard assumption in science teaching that some pedagogies in science classrooms can serve a dual function—improve the student-perceived teacher quality and improve students' affinity to STEM professions. We asked 7507 freshmen from 40 colleges in the United States, selected in a stratified random procedure, to retrospectively report their experiences of a list of 32 pedagogies during high school biology, chemistry, and physics classes. Our survey also asked students to rate each teachers' quality and to report their Science, Technology, Engineering, or Mathematics career interests at the beginning and end of high school. We found that teachers' chosen pedagogies, on the whole, had a stronger impact on how students rated them than on students' career interests. Interestingly, we also found considerable differences between the disciplines.

In teacher professional development (PD), grouping teachers with varying levels of experience can be a productive and empowering way to stimulate the exchange and co-generation of content and pedagogical knowledge. However, less experienced teachers can face socio-emotional risks when engaging in collaborative science content reasoning tasks with more experienced colleagues, and these risks may impact the collaborative experience of both parties and the learning environment in teacher PD. This exploratory case study examines the process of productively navigating socio-emotional risks and interpersonal tensions encountered by a veteran and pre-service physics teacher during one episode of discussing physics content. We use a single term, comfort-building, to encapsulate discursive moves that result in increased feelings of comfort and safety by the participants. Comfort-building includes moves that serve to mitigate social risk, ease tension, and avoid discomfort, as well as those geared toward finding common ground and co-navigating challenges. These moves can carve out conversational space for teachers to more confidently face risks associated with being accountable to the physics content knowledge and engage in discipline-based conversations more deeply. The presented case was followed by video-stimulated individual interviews to determine how consciously the teachers connected their participation to explicit risk and comfort. This case study highlights an affective dimension for consideration in the continued study and facilitation of science teacher PD, especially programs that bring together teachers with a variety of backgrounds and skill sets.
