The early years of teaching are important for science teachers, but little is known about how science teachers develop professionally in their early years. This mixed methods study took a longitudinal view of the early years of teaching. Following 95 secondary science teachers over a 5-year period, this study examined the beliefs, pedagogical…

Previous research about the presence of nature of science (NOS) within science textbooks has been found to be lacking in sufficient coverage. However, given the shift in how scholars conceive of NOS, the shortcomings may not be present in the textbooks but rather in the NOS frameworks used to analyze textbooks. Whereas traditional NOS has taken a…

Students often fail to utilize what they know about one topic (e.g., hemodynamics) when attempting to master another topic involving a similar phenomenon (e.g., airflow in airways). What accounts for this difficulty that students have? And how can students be assisted in doing a better job of applying what they already know to new topics? The…

The main aim of this paper is to address the increasing need for science-art integration across all levels of education globally. Specifically, the need to identify a signature pedagogy for the Global Science Opera (GSO) that can be used in teaching and learning contexts in formal and non-formal education. This part of the paper draws upon the…

A subject of physics includes various complex and sophisticated concepts that pose a challenge for both instructors to teach and students to grasp the clarity in the subject. Many researchers have discussed this challenge toward adopting an appropriate approach to teach physics in the institution. Therefore, the study reviews the research articles…

Difficulties presented by students on the concept of instantaneous velocity are well known. This is in part due to instantaneous speed being often defined in terms of the notion of mathematical limit, which may not be clear to many students in introductory physics courses. In this work we present a complementary teaching proposal that can help…

The purpose of this study was to examine the effects of phenomena-based inquiry on students' engagement levels in my science classroom. This action research study took place in the fall of 2021 with six student participants. Participants were enrolled in an 8th grade honors science course in a middle school in South Carolina. The research was…

Atomic orbitals represent an essential construct used to develop chemical bonding models, upon which other more advanced chemistry topics are built. In this article, we share a series of active-learning activities and a gamified approach to develop students' representational competence about atomic orbitals and to engage students in learning the…

Laboratory activities are a prevalent and essential part of chemistry learning because of their potential to help students develop problem solving abilities, visualize chemistry concepts learned in lecture, and gain practical skills. However, learning in the laboratory environment is not without its challenges. For example, cookbook-style…

There have been many attempts to address the deficits in traditional teaching methods for decades Multiple studies have been done on the Common Knowledge Construction Model (CKCM) and the results of each study has shown an improvement. The addition of relational conceptual change has added much needed improvement in teaching science. This study,…

Cultivating students' scientific knowledge and developing their capability in scientific inquiry depends on a teacher's ability to use existing resources to design rich learning opportunities. Designing such experiences is not easy, and is particularly challenging for new teachers who have little experience making decisions about the best way to…

"Cases are stories with a message. They are not simply narratives for entertainment. They are stories to educate" (Herreid, 1997, p. 92). By this definition, a case study is two things: a story and a strategy to drive learning. Although the story typically comes from a narrative purposefully written for the classroom, such as the case…

Despite the prevalent use of observational measures in teacher evaluation systems, research has only recently begun to take into account how aspects of the instructional environment and lesson sampling design may interact with teachers' scores on these measures. Instead, one assumption guiding current evaluation systems is that the variation in…

The implementation of context-based chemistry programs has been started before 40 years ago since 1980s in an attempt to make the learning of chemistry more meaningful for students. Consequent to its lengthy, there has been a steady increase in the number of interventional context-based (ICB) approach chemistry studies investigating the effect of…

Science education reform efforts have emphasized the incorporation of more authentic and meaningful scientific practices into formal learning environments. With this focus on practices, such as scientific modeling, a powerful tool for sense-making and reasoning, comes a need to observe and understand if and how it is actually occurring,…
