Many biology students struggle to learn about the process of meiosis and have particular difficulty understanding the molecular basis of crossing over and the importance of homologous pairing for proper segregation. To help students overcome these challenges, we designed an activity that uses a newly developed Chromosome Connections Kit® from 3-D…

We describe the development, design, implementation, and preliminary classroom results of an innovative curriculum, "Focus on Energy," that supports learning about energy in Grades 4-5. The curriculum is grounded in the concepts of science as practice, model-based reasoning, and learning progressions, and builds on students' pre-existing…

Although physical hands-on laboratory experiments are commonly used in schools, virtual laboratory environments are also being used in science classrooms. Their possibilities and impact on students' achievement, conceptual understanding, and inquiry skills have been investigated by other researchers. Yet, it is difficult to find studies about the…

Background: Bringing about conceptual change in school science classrooms is difficult for teachers. Researchers in this field have struggled to influence classroom practice. Purpose: The present research presents a method and a framework for video-based pedagogy analysis. Sample: Six groups of 11-year-old pupils took part (three girls and three…

This article aims to explore the experiences of science instructors who are active participants in the design and enactment of an interdisciplinary science course with student-centered pedagogy in a large-enrollment class. The data were collected through interviews with instructors and analyzed using the inductive thematic approach. Results show…

During the SARS-2-COVID pandemic our institution sought to continue the teaching and learning of experimental laboratories by designing, assembling, and delivering a microscale chemistry kit to the students' homes. Thanks to this approach students were able to perform [approximately]25 experiments during each one of the Fall 2020 and Spring 2021…

Teachers are highly reliant on textbooks for teaching. In the Republic of Korea, science textbooks help students to understand scientific terms through inquiry activities. However, there is a lack of analysis on whether the inquiry activities suggested in these textbooks appropriately cover the terms included in the main text. Therefore, this…

This study examined the predictive effect of students' perceptions of science teacher's autonomy support and classmates' support on their basic psychological needs (i.e., relatedness, autonomy, and competence) in science. 1,018 middle school students from 9 public schools in Turkey completed self-report surveys. Hierarchical multiple regression…

Facilitating discussions is a key approach that science teachers use to engage students in scientific argumentation. However, learning how to facilitate argumentation-focused discussions is an ambitious teaching practice that can be difficult to learn how to do well, especially for preservice teachers (PSTs) who typically have limited…

A significant issue in the teaching, learning and summative assessment of practical science is that the underpinning model of scientific methods is based on a fairly simplistic and linear account that does not represent how scientists actually do practical work. In this paper, we examine how science teachers in England and Wales view scientific…

Modeling, which is the process of constructing, testing, and refining models, is an important skill in experimental physics, and thus a learning goal of many physics laboratory classes. One promising approach to help students develop modeling skills is to incorporate multiweek student-designed projects into lab courses. In order to assess the…

In the past decade, emphasis on promoting "climate literacy" in K-16 science classrooms has increased. Teachers play a critical role in cultivating these opportunities, especially in secondary science classrooms. However, most prior climate education research has focused on students and student learning; little is known about how…

This study explored the situational interest and emotional valence of 13-year-old students (N = 94) participating in a five-session science course. The relationship between students' situational interest and emotional valence and their individual interest was also studied. During each session, students participated in a collaborative learning…

Cartoons are an effective alternative to create a rich learning environment that is visually and audibly equipped for students in an effective science education. It is of upmost significant for science teachers to possess the necessary knowledge, activity experience and equipment in order to carry out a qualified science teaching. Therefore, the…

Lesson study (LS) is an effective means of improving teachers' facility with teaching design. This research designs a case study of online to offline (O2O) LS and explores the social interaction and behaviour patterns in the process of the LS. The participants included 29 chemistry teachers from 10 secondary schools and two educational technology…
