Teacher professional development (PD) is essential to continuously improve teaching skills, to adapt to diverse student needs, and to promote equity and inclusion. Only a few studies to date have synthesized how PD programs improve teachers' content knowledge and instructional quality, as well as students' academic performance. In this…

With an educational issue that has caught the attention of many countries in the world (study load), a population of 8th graders from a typical Chinese metropolitan city (40,536 from 118 schools), and an advanced statistical strategy (multilevel piecewise regression), we examined whether there was a turning point in terms of the effects of study…

When elementary schools integrate literacy and science instruction, they create rich learning environments that allow students to develop an understanding of science ideas while improving their reading, writing, and speaking skills at the same time. Neither subject takes a back seat. Literacy instruction supports science and science instruction…

Science educators incorporate collaborative engagement in model-based argumentation to meet curricular goals and build students' capacity for scientific epistemic and social practices. During collaboration, groups encounter various challenges (e.g., lack of task understanding) and engage in social regulation to overcome them. However, little is…

Elementary schools face pressures to substantially increase student achievement in all subjects with limited time in the school day. In particular, science struggles to gain instructional momentum due to many internal and external factors. The school district of Wynne (pseudonym), located within the Commonwealth of Massachusetts, has generational…

Through the lens of science capital, this research aims to detect the key factors and their main effects in identifying students with science-related career expectations. A machine learning approach (i.e., random forest) was employed to analyze a dataset of 519,334 15-year-old students from the Programme for International Student Assessment (PISA)…

This paper presents a study of children's ideas of the body's internal structure. Children between four and 13 years (N = 170) individually produced drawings. During each drawing session the children explained their drawings to a facilitator and added written labels either by themselves or, if they were too young to write, with the facilitator's…

Access and personalized instruction required for laboratory education can be highly compromised due to regulatory constraints in times such as COVID-19 pandemic or resource shortages at other times. This directly impacts the student engagement and immersion that are necessary for conceptual and procedural understanding for scientific…

Besides measures of students' performances, a valid assessment of students' efficiency in a teaching process should also include measures of invested mental effort. The research presented herein covers several approaches in measuring students' mental effort including 5, 7 and 9-point Likert type scales, time on task, as well as eye tracking…

In this feasibility study, we present a newly developed observational system, Optimizing Learning Opportunities for Students (OLOS). OLOS is designed to elucidate the learning opportunities afforded to individual children within early childhood classrooms and as they transition to formal schooling (kindergarten through third grade). OLOS records…

Each game within the Ignite by Hatch™ gaming environment belongs to an overall developmental domain and skills-based subdomain and is intended to meet the developmental needs of children at specific skill levels. These skill levels (Beginning, Emerging, Intermediate, Accomplishing, and Proficient+) form an intended developmental pathway. Children…

The current study investigated how a guidance method that segments a complex task into simpler subtasks affects adults' inquiry-based learning in a science simulation environment. In a multivariate inquiry task, participants were asked to investigate the effects of all variables in one round of inquiry. In another group, participants were guided…

Science education reform efforts in the Unites States call for a dramatic shift in the way students are expected to engage with scientific concepts, core ideas, and practices in the classroom. This new vision of science learning demands a more complex conceptual understanding of student engagement and research models that capture both the…

This paper presents an integrative framework for analyzing science meaning-making with representations. It integrates the research on multiple representations and multimodal representations by identifying and leveraging the differences in their units of analysis in two dimensions: timescale and compositional grain size. Timescale considers the…

The Association of American Colleges and Universities ranks multiple process of science (POS) skills among the top-10 skills employers seek in college graduates. As part of an effort to explore and align the emphasis on POS skills in our science departments, we sought three things: (a) to determine if faculty and students felt enough time was…
