The purpose of this case study, informed by a Lakatosian perspective, is to identify how an alternative conception that originates in present learning but is related directly to subsequent learning contexts can be constructed. Before the study, one of the authors found by accident that a student who had learned about Avogadro's principle and…

Informal learning environments such as Natural History Museums can introduce visitors to a variety of topics in evolution by providing accessible representations of concepts like geological time, evolutionary mechanisms, biological diversity, geological time, and fossil dating. Our study examined sixth-grade students' conceptualization of…

The Transformative Experience Questionnaire (TEQ) has previously been used only in formal science learning environments to examine how students' learning experiences extend beyond the classroom into their daily lives. In the present study, an example of how this tool can be useful to assess transformative experiences in an informal learning…

Student engagement is widely considered to be a multidimensional construct consisting of behavioral, cognitive, and affective components. Recent research has examined student engagement in science learning contexts using holistic approaches that account for multidimensionality through the identification of engagement profiles. However, it is not…

This article reports on quantitative findings from a design-based implementation research (DBIR) project "Carbon TIME" that focused on teaching carbon cycling at multiple scales, from atomic-molecular to global. We report results from a large dataset from diverse schools, including 59,654 student assessments of three-dimensional learning…

The interrelationship of science and engineering and the recent inclusion of engineering in K-12 science standards have promoted the incorporation of engineering design in science classrooms. However, empirical studies on the impacts of engineering design on science learning show mixed findings and indicate that factors such as the complexity of…

The study investigated the influence of a connected learning approach for explicit nature of science (NOS) instruction and explicit argumentation instruction, in comparison with a non-connected approach, on students' NOS conceptions and argumentation skills. Participants comprised 42 students enrolled in two sections of grade 10 that were randomly…

Student science proficiency development demands sustainable and coherent learning environment support. Scholars argue that project-based learning (PBL) is an efficient approach to promoting student science learning, compared to conventional instructions. Yet, few studies have delved into the learning process to explore how a coherent PBL system…

The Framework for K-12 Science Education set an ambitious goal of broadening participation in science learning for all students. Meeting this vision will involve supporting teachers in making meaningful connections with the cultural and linguistic resources their students bring to school; in essence, developing pedagogies that frame these…

Design-based learning is considered a powerful way to help students apply and develop understanding of science concepts, but research has shown that the success of this approach is not a given. Examining students' understanding of science concepts in various design-based learning contexts has thus continued to be an important field of research. To…

It is widely recognized that we need to prepare students to think with data. This study investigates student interactions with digital data graphs and seeks to identify what might prompt them to shift toward using their graphs as thinking tools in the authentic activity of doing science. Drawing from video screencast data of three small groups…

Demand for engineering-interested and proficient high school graduates continues to grow across the nation. However, there remains a severe gap in college participation and employment in engineering fields for students with learning disabilities (SWLDs). One potential way to encourage SWLDs to consider engineering as a profession and promote the…

Learning progressions are theoretical models that describe learning of scientific ideas and practices over time. These hypothetical progressions need to be tested and refined in order to productively inform instruction and assessment. In this paper, we report our attempts to revise a learning progression in genetics. In particular, we focused on…

Energy is a central concept across the sciences and an important goal of science education is to support all students so that they develop a full understanding of the energy concept. However, given the abstract and complex nature of the energy concept, only a few students develop an understanding so that they can use energy ideas to make sense of…

The Framework for K-12 science education (The "Framework") and Next Generation Science Standards (NGSS) emphasize the usefulness of learning progressions in helping align curriculum, instruction, and assessment to organize the learning process. The "Framework" defines three dimensions of science as the basis of theoretical…
