Students come to class with ideas about science content and the practices used to generate knowledge. Their lived experience provides them with basic ideas about how the world works. Tapping into their innate understandings and testing their ideas allows them to construct a more accurate understanding. Research shows that all students are ready to…

The ideas students bring to class and their perspectives on what is happening in the classroom change constantly. Keeping track of these changes is useful for adapting lessons, nurturing student self-reflection, increasing student ownership of learning, and building a teaching practice responsive to learners' needs. In this article, the authors…

This column provides ideas and techniques to enhance your science teaching. This month's issue discusses using the 5E learning cycle to create coherent storylines. The 5E learning cycle provides an important framework to help teachers organize activities. To realize the full potential of the 5E framework for student learning, lessons must also…

A distinguishing feature of all the formative assessment probes in the "Uncovering Student Ideas" series is that each probe has two parts: (1) a selected answer choice that usually mirrors the research on commonly held ideas students have about concepts or phenomena; and (2) an explanation that supports their answer choice. It is this…

By the age of seven, many children would have eaten jelly and many would have experienced its preparation by watching adults. This small scale study explores the use of different levels of thinking skills and language in discussing the process of jelly making among Grade 2 students. Semi-structured, one-to-one interviews with fifteen students were…

For the past five summers, the authors have taught summer school to recent immigrants and refugees. Their experiences with these fourth-grade English language learners (ELL) have taught them the value of using models to build scientific and mathematical concepts. In this article, they describe the use of different forms of 2- and 3-D models to…

This study examines the process by which a teacher may be able to answer a question asked in the classroom by using a scientific approach and a simple activity. This article examines a discussion of the question "Is space light or dark?" Priority in the discussion has been given to determining students' preconceptions about the interaction of…

Cellular respiration and metabolism are topics that are reportedly poorly understood by students and judged to be difficult by many teachers. Although these topics may not be required learning areas in some high school biology curricula, a grasp of fundamental concepts of cellular metabolic processes is advantageous for students undertaking (or…

The purpose of many animal studies at early grades is to build observation skills, develop a knowledge base, and practice age-appropriate science skills like comparing, describing, and drawing. While these are important learning experiences, the National Science Education Standards also recommend that students engage in scientific inquiry (NRC…

Adaptive chemical behavior is essential for an organism's function and survival, and it is no surprise that biological systems are capable of responding both rapidly and selectively to chemical changes in the environment. To elucidate an organism's biochemistry, its chemical reactions need to be characterized in ways that reflect the normal…

This study examined a Thai biology teacher's creative tensions when she was challenged to adopt a new teaching approach to photosynthesis with her class. The teacher was purposively selected on her need of professional growth. Data from observations and interviews documented the tensions. The data indicated that the biology teacher experienced…

When watching a small child with a toy car, it is seen that interest in motion comes early. Children often suggest speed through sounds such as "RRRrrrRRRooooommMMMmmmm" as the toy car is made to speed up, slow down, or accelerate through a turn. Older children start to consider force and motion studies in more detail, and experiences in school…

This study describes the multiple analogical models used to introduce and teach Grade 12 chemical equilibrium. We examine the teacher's reasons for using models, explain each model's development during the lessons, and analyze the understandings students derived from the models. A case study approach was used and the data were drawn from the…

Given the important role of science teacher educators in developing science teachers' understandings of nature of science (NOS), this study explores 15 Turkish "prospective" science teacher educators' beliefs about NOS in the context of teacher education reform in Turkey. A reflection-oriented qualitative approach was adopted in the…

Examines the proposed definition of biological literacy as the understanding of a small number of pervasive biological principles appropriate to making informed personal and societal decisions. Utilizes the content of a major daily newspaper to adjust biology instruction to focus on this notion of biological literacy. Discusses benefits and…
