The National Curriculum for England has been revised and the statements on energy have some new phrasing and some new ideas. In this article, I will reflect on how these changes might be beneficial, relieving some of the strictures of previous drafts and providing opportunities to talk about energy in new, more constructive ways. I will discuss…

The study investigated the common misconceptions of lower secondary school students regarding the concepts of photosynthesis and plant respiration. These are abstract concepts which are difficult to comprehend for adults let alone for lower secondary school students. Research of the students misconceptions are conducted worldwide. The researches…

This article describes an interrupted case study that intersperses information about diffusion and osmosis with content review and knowledge application questions, as well as a simple experiment that can be conducted without the use of a laboratory. The case study was developed for use in an introductory undergraduate biology course. The case…

Given the diversity of materials in our surroundings, one should expect scientifically literate citizens to have a basic understanding of the core ideas and practices used to analyze chemical substances. In this article, we use the term 'chemical identity' to encapsulate the assumptions, knowledge, and practices upon which chemical…

Three-dimensional (3D) nuclear charts were created using toy blocks, which represent the atomic masses per nucleon number and the total half-lives for each nucleus in the entire region of the nuclear mass. The bulk properties of the nuclei can be easily understood by using these charts. Subsequently, these charts were used in outreach activities…

This paper describes the design and impact of an inquiry-oriented online curriculum that takes advantage of dynamic molecular visualizations to improve students' understanding of chemical reactions. The visualization-enhanced unit uses research-based guidelines following the knowledge integration framework to help students develop coherent…

Argumentation is one of the central practices in science learning and helps deepen students' conceptual understanding. Students should learn how to communicate ideas including procedure tests, data interpretations, and investigation outcomes in verbal and written forms through argument structure. This article presents a negotiation model to…

In recent years, school science has been the target of increasing critique for two reasons. On the one hand, it is said to enforce "epic" images of science that celebrate the heroes and heroic deeds that established the scientific canon and its methods and thereby falsifies the history and nature of science. On the other hand, the…

Like the figurative apple for the teacher, the tomato is a well-known food symbol representing a variety of cuisines. We drew on current scientific research and partnerships with classroom teachers to develop a case study activity consisting of four layers to teach concepts of plant biology and genetics to middle and high school students. The goal…

This paper discusses the nature of learner engagement with science content during small group discussions in which learners use their home languages. We observed that learners reverted to their home languages in small group discussions, yet very little is known about the dynamics of learner engagement when they use their home languages in…

Increasingly, teacher leadership is being recognized as an essential ingredient in education reforms; however, few teachers consider themselves leaders. Becoming a leader is not just acquiring knowledge and skills for leadership, but developing a new "professional identity." As teachers become leaders, however, this identity might put…

The role of emotion during learning encounters in science teacher education is under-researched and under-theorized. In this case study, we explore the emotional climates (ECs), that is, the collective states of emotional arousal, of a preservice secondary science education class to illuminate practice for producing and reproducing high quality…

An understanding of how genomics information, including information about risk for common, multifactorial disease, can be used to promote personal health (personalized medicine) is becoming increasingly important for the American public. We undertook a quantitative content analysis of commonly used high school textbooks to assess how frequently…

Hands-on activities with live organisms allow students to actively explore scientific investigation. Here, I present activities that combine guided inquiry with direct instruction and relate how nutrition affects the physiology and behavior of the common housefly. These experiments encourage student involvement in the formulation of experimental…

This paper compares the performance of students at a high-performing U.S. public school (n = 64) on the advanced placement (AP) chemistry exam to their performance on the ChemQuery assessment system. The AP chemistry exam was chosen because, as the National Research Council acknowledges, it is the "perceived standard of excellence and school…
