Background: In science education asynchronous online interactions have increased dramatically during the recent pandemic and some of these practices will stay. One of the characteristics in asynchronous exchanges is the spacing and sequencing of online interaction. It means that dialogue partners do not necessarily receive immediate feedback as is…

Background: With a growing new materialism paradigm and research on multimodality, there is an increasing attention on the role of material objects in science teaching and learning. However, there is currently no available framework, coding scheme, or method of inquiry to specifically analyze the use of material objects in science meaning-making.…

Background: In the field of science education, the importance of assessment in students' learning process has been recognized. Understanding of how students perceive science assessment and feedback may be an important issue that science education researchers need to pay attention to in order to achieve meaningful learning. Purpose: The purpose of…

Background: In many classrooms, science textbooks remain a significant tool, functioning in some instances as the de facto curriculum and influencing pedagogical practices. Such conventions are more noticeable in the science classrooms of developing countries, like Jamaica, because of a chronic shortage of specialist science teachers and the…

Background: In recent years, science curricula (chemistry, physics, biology, earth science, life science, etc.) in many countries have been prepared and applied according to the inquiry-based learning approach. Although the acquisition and application of the inquiry skills are one of the important objectives of the science curriculum, the inquiry…

Background: This article describes the design and the evaluation of a student lab program on the topic of nanoscience and technology (NST), mainly focusing on Nanoscience and its applications. The program was designed for students in grades 8-10 and was part of a larger outreach program of the Collaborative Research Center 'Function by Switching'…

Background: Density is difficult to learn and teach in middle schools. This study, hypothesizing that the density concept develops as part of a conceptual system, used a conceptual change approach to teaching density. The approach emphasized the use of multiple strategies to teach the density concept and the associated concepts in the conceptual…

Background: One of the most important goals of science education is to enable students to understand the nature of science (NOS). However, generally regular science teaching in classrooms does not help students improve informed NOS views. Purpose: This study investigated the influence of an explicit reflective conceptual change approach compared…
