Understanding the relationship between energy and temperature can be challenging, but it is crucial to developing an understanding of the underlying mechanism behind climate change. In this article, the authors review the development of a unit that focuses on the relationship between energy, greenhouse gases, aerosols (a suspension of fine solid…

The internet is prevalent in society today, and user-friendly web-based productivity tools are readily available for developing diagnostic instruments. This study sought to determine the affordances of a web-based diagnostic instrument on ionisation energy (wIEDI) based on the pen-and-paper version, the Ionisation Energy Diagnostic Instrument…

This paper presents a revised learning progression for the energy concept and initial findings on diverse progressions among subgroups of sample students. The revised learning progression describes how students progress towards an understanding of the energy concept along two progress variables identified from previous studies--key ideas about…

Lay conceptions of energy often conflict with scientific knowledge, hinder science learning and scientific literacy, and provide a basis for ungrounded beliefs. In a sample of Finnish upper secondary school students, energy was attributed with features of living and animate beings and thought of as a mental property. These ontologically confused…

The concept of energy is central to all the science disciplines, seamlessly connecting science, technology, and mathematics. For high school and upper middle school teachers, this compendium comprises inquiry-based activities, lesson plans, and case studies designed to help teach increased awareness of energy, environmental concepts, and the…

The results from a study to explore pre-service teachers' understanding of ionization energy, a topic that features in A-level (grade 11 and 12) chemistry courses. in Singapore , is described. A previous study using a two-tier multiple choice diagnostic test has shown that Singapore A-level students have considerable difficulty understanding the…

Principles of Technology was designed as a high school course in applied science for vocational students in the 11th and 12th grades in Leander, Texas. It consists of a 2-year curriculum covering 14 units in applied physics: (1) force; (2) work; (3) rate; (4) resistance; (5) energy; (6) power; (7) force transformers; (8) momentum; (9) waves and…

This instructional unit for use in 11th and 12th grade social studies and science courses contains six classroom lessons dealing with United States energy policy. The overall objective is to help students understand how circumstances, present and proposed legislation, political action, and the Constitution itself become linked in the development…

The instructional materials and classroom activities described in the document are intended to aid teachers in grades 10 through 12 develop and implement educational programs dealing with energy-related issues. The document is presented in four sections. Section I explains the organization of the document and summarizes how teachers should…
