Concept mapping is widely used as a tool for assessing students' understanding of science. To fully realize the diagnostic potential of concept mapping, a scoring method that not only provides an objective and accurate assessment of students' drawn concept maps but also provides a detailed understanding of students' proficiency and deficiencies in knowledge is necessary. However, few of the existing scoring methods focus on the latent constructs (e.g., knowledge, skills, and cognitive processes) that guide the creation of concept maps. Instead, they focus on the completeness of the concept map by assigning a composite score, which makes it difficult to generate targeted diagnostic feedback information for advancing students' learning. To apply the diagnostic classification model to the quantitative analysis of concept maps, this study introduced the novel application of the item expansion-based diagnostic classification analysis (IE-DCA) for this purpose. The IE-DCA can not only assess students' concept mapping abilities along a continuum but also classify students according to their concept mapping attributes when constructing the concept maps. The application and benefits of this approach were illustrated using a physics concept-mapping item related to particle and rigid body. Results showed that the estimated attribute profiles via the IE-DCA provided more detailed information about students' latent constructs than the composite score. Overall, this study illustrates the feasibility and potential of applying IE-DCA to analyze concept maps. Future applications of IE-DCS in other assessments in science education are discussed.

To increase participation of students of color in science graduate programs, research has focused on illuminating student experiences to inform ways to improve them. In biology, Black students are vastly underrepresented, and while religion has been shown to be a particularly important form of cultural wealth for Black students, Christianity is stigmatized in biology. Very few studies have explored the intersection of race/ethnicity and Christianity for Black students in biology where there is high documented tension between religion and science. Since graduate school is important for socialization and Black students are likely to experience stigmatization of their racial and religious identity, it is important to understand their experiences and how we might be able to improve them. Thus, we interviewed 13 Black Christian students enrolled in biology graduate programs and explored their experiences using the theoretical lens of stigmatized identities. Through thematic content analysis, we revealed that students negotiated experiences of cultural isolation, devaluation of intelligence, and acts of bias like other racially minoritized students in science. However, by examining these experiences at the intersection of race/ethnicity and religion, we shed light on interactions students have had with faculty and peers within the biology community that cultivated perceptions of mistrust, conflict, and stigma. Our study also revealed ways in which students' religious/spiritual capital has positively supported their navigation through biology graduate school. These results contribute to a deeper understanding of why Black Christian graduate students are more likely to leave or not pursue advanced degrees in biology with implications for research and practice that help facilitate their success.

This article presents a simple, cognitive theory of science and learning. The first section of the paper develops the theory's two main propositions: (i) A wide range of scientific activities rely heavily on one type of reasoning, hypothetical thinking, and (ii) This type of reasoning is also useful to students for learning science content. The second section of the paper presents a taxonomy of multiple-choice questions that use hypothetical thinking and the third section of the paper tests the theory using data from a college biology course. As expected by the theory, student responses to 24 scientific reasoning questions were consistent with a one-dimensional psychometric construct. Student responses to the scientific reasoning questions explained 36% of the variance in exam grades. Several directions for additional research are identified, including studying the psychometric structure of scientific thinking in more detail, performing randomized, controlled experiments to demonstrate a causal relationship between scientific thinking and learning, and identifying the relative contribution of other factors to success in college.

Classroom discussions have become a centerpiece of reform efforts in science education because talk mediates the joint co-constructing of knowledge in science classrooms. Although decades of research underscore the importance of talk in supporting science learning, the science education community continues to grapple with how to support teachers and students in navigating the uncertainty that is associated with doing knowledge building work. To address these challenges, we must examine not just what gets constructed (the scientific ideas), but how knowledge is co-constructed by teachers and students (the process of building those ideas) amidst uncertainty. In this study, we propose a conceptual tool for identifying organizational, epistemic, and interpretive metadiscourse markers (MDMs) in science talk. We highlight how teachers and students use these three types of MDMs as they navigate uncertainty while connecting ideas within and across multiple turns of talk, leveraging resources for knowledge building, and making interpretations about one another's ideas. We conclude with a set of suggestions for how researchers and teachers can utilize this framework to attend to the ways that MDMs index the organizational, epistemic, and interpretive dimensions of uncertainty in the knowledge building process.

Science should provide students an accurate and contemporary education on genetic influence, particularly how it impacts trait variability and developmental norms. Stories involving familial, racial, and sexual differences routinely appear in the popular media and sales of over-the-counter genetic tests are mounting. Unfortunately, research suggests genetic curricula in secondary education and university courses have little impact on genetic literacy; instead they appear to amplify genetic essentialism. This position paper reports on genetic essentialism, the impact of three components of science education (teachers, students, curriculum), and critiques existing genetic lessons in two prevalent scientific disciplines, biology and psychology. Two entrenched 19th century genetic paradigms (e.g., Mendelian inheritance and behavioral genetics) are specifically examined. The paper closes with specific recommendations for improving students' genetic literacy including important contemporary genetic science (e.g., epigenetics) and instructional approaches (e.g., learning progression, refutational teaching).

Creating inclusive and supportive environments in science, technology, engineering, and mathematics (STEM) educational settings are important tools for countering racially hostile academic spaces and attracting and retaining talented Black and African American students. STEM faculty and other university members may display Black Lives Matter and similar signs of solidarity to express their support for Black students. However, how Black students perceive such signs is unknown. On the one hand, the identity safety cue literature suggests such signs relate to increased comfort and a sense of belonging among individuals from minoritized groups. On the other hand, some contemporary perspectives toward Black Lives Matter and other signs of solidarity have been criticized for lacking substance and impact. Given the extant literature's omission of Black students' perspectives about signs of solidarity, the current study employed semi-structured interviews and qualitative analytic methods to solicit and analyze the perspectives of 12 Black STEM graduate students. The findings revealed a general preference for some signs over others, as well as nuanced perspectives toward each sign of solidarity. Implications for STEM researchers and faculty who aspire to support Black students are discussed. Further, recommendations for adopting an informed ally approach are provided.

The purpose of this study was to test predictability of environmental moral reasoning patterns of preservice science teachers (PSTs) by their epistemological beliefs and values. Four environmental moral dilemma scenarios that reflect different environmental moral dilemma situations taking place in four outdoor recreation contexts (i.e., hiking, picnicking, fishing, camping) were used to trigger and examine environmental moral reasoning of PSTs. Centers of moral concerns (i.e., ecocentric, anthropocentric, egocentric) and underlying reasons of environmental moral considerations (e.g., aesthetical concerns, justice issues) were used to investigate PSTs' environmental moral reasoning patterns. Data were collected from 1524 PSTs enrolled in six universities located in Central Anatolia region of Türkiye. A path model was proposed to test relationships of PSTs' epistemological beliefs and values to their environmental moral reasoning for each environmental moral dilemma scenario. Results indicated good-fit between study data and the path model tested for each environmental moral reasoning scenario. Variances in environmental moral reasoning scores that were explained by the path models had small to medium effect size values of 0.06 to 0.26. Statistical significance and direction of the tested relationships showed changes depending on the moral dilemma scenario context and focus of environmental moral reasoning. Nevertheless, path analyses consistently revealed positively significant relationships between environmental moral reasoning categories and epistemological beliefs in omniscient authority and self-transcendence and tradition values. Implications for science education policy and practice are discussed.

As professional science becomes increasingly computational, researchers and educators are advocating for the integration of computational thinking (CT) into science education. Researchers and policymakers have argued that CT learning opportunities should begin in elementary school and span across the K-12 grades. While researchers and policymakers have specified how students should engage in CT for science learning, the success of CT integration ultimately depends on how elementary teachers implement CT in their science lessons. This new demand for teachers who can integrate CT has created a need for effective conceptual tools that teacher educators and professional development designers can use to develop elementary teachers' understanding and operationalization of CT for their classrooms. However, existing frameworks for CT integration have limitations. Existing frameworks either overlook the elementary grades, conceptualize CT in isolation and not integrated into science, and/or have not been tested in teacher education contexts. After reviewing existing CT integration frameworks and detailing an important gap in the science teacher education literature, we present our framework for the integration of CT into elementary science education, with a special focus on how to use this framework with teachers. Situated within our design-based research study, we (a) explain the decision-making process of designing the framework; (b) describe the pedagogical affordances and challenges it provided as we implemented it with a cohort of pre- and in-service teachers; (c) provide suggestions for its use in teacher education contexts; and (d) theorize possible pathways to continue its refinement.

Previous studies have documented the promising results from student-constructed representations, including stop-motion animation (SMA), in supporting mechanistic reasoning (MR), which is considered an essential thinking skill in science education. Our current study presents theoretically and empirically how student-constructed SMA contributes to promoting MR. As a theoretical perspective, we propose a framework hypothesizing the link between elements of MR and the construction nature of SMA, that is, chunking and sequencing. We then examined the extent to which this framework was consistent with a multiple-case study in the domain of static electricity involving five secondary school students constructing and using their own SMA creation for reasoning. In addition, students' reasoning in pre- and postconstruction of an SMA was examined. Our empirical findings confirmed our framework by showing that all students identified the basic elements of MR, that is, entities and activities of entities, when engaging in chunking and sequencing. Chunking played a role in facilitating students to identify entities responsible for electrostatic phenomena, and sequencing seemed to elicit students to specify activities of these entities. The analysis of students' reasoning in pre- and postconstruction of SMA found that student-generated SMA has a potential effect on students' retention of the use of MR. Implications for instruction with SMA construction to support MR are discussed.
以往的研究已经证明,学生构建的表征(包括定格动画(SMA))在支持机械推理(MR)方面具有良好的效果,而机械推理被认为是科学教育中的一项基本思维技能。我们目前的研究从理论和实证角度介绍了学生构建的定格动画如何有助于促进机械推理。作为一个理论视角,我们提出了一个框架,假设MR要素与SMA的构建性质(即分块和排序)之间存在联系。然后,我们考察了这一框架与一项静电领域的多案例研究的一致性程度,该研究涉及五名中学生构建并使用自己的 SMA 作品进行推理。此外,我们还考察了学生在构建 SMA 前后的推理过程。实证研究结果表明,所有学生在进行分块和排序时,都能识别 MR 的基本要素,即实体和实体的活动。分块在促进学生确定静电现象的实体方面发挥了作用,而排序似乎能激发学生明确这些实体的活动。通过分析学生在构建 SMA 前后的推理,发现学生生成的 SMA 对学生保持 MR 的使用有潜在影响。本文还讨论了通过构建SMA来支持MR教学的意义。

Taking on an agentic perspective, this study employed a digital ethnographic approach to examine a science teacher's emotional experiences in an online graduate science education course during the COVID-19 pandemic. Veronika, the teacher, revealed her feelings of grievance and loss to the graduate course cohort at the advent of large-scale school closures. Her emotions, shared through the online course, connected the members of the cohort to overcome emotional and pedagogical difficulties caused by the pandemic. She received both emotional and professional support from the cohort and designed an environmental related learning activity that centered on fun and connection in science learning. The activity stimulated students’ positive emotions and simultaneously served to reset Veronika's emotions. This study underlined that emotions connect teachers during a social crisis in ways that address obstacles encountered in teaching and learning. Lessons for teacher education include providing space for and acknowledging emotions in teaching, especially in times of stress and the importance of fostering agentic actions, collegiality, and collaboration by explicitly connecting an individual's emotions and beliefs to their professional practice.

Veronika, the teacher, revealed her feelings of grievance and loss to the graduate course cohort at the advent of large-scale school closures. Her emotions, shared through the online course, connected the members of the cohort to overcome emotional and pedagogical difficulties caused by the pandemic. She received both emotional and professional support from the cohort and designed an environmental related learning activity that centered on fun and connection in science learning. The activity stimulated students’ positive emotions and simultaneously served to reset Veronika's emotions.
