The real time PCR (qPCR) method provides a powerful method to assess levels of particular species of DNA. When combined with reverse transcription (RT-qPCR) it is the predominate technique to measure expression of gene transcripts. While this approach is very powerful, particular care must be taken in the design of the primers to facilitate…

Science teachers can always benefit from efficient tools that help students to engage with the subject and understand it better without significantly adding to the teacher's workload nor requiring too much of class time to manage. Reflective writing is such a low-impact, high-return tool. What follows is an introduction to reflective writing, and…

Traditional methods for teaching the Lewis dot structure model emphasize rule-based learning and often neglect the purpose and function of the model. Thus, many students are unable to extend their understanding of molecular structures in new contexts. The assignment described here addresses this issue by asking students to read and write about the…

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…

Children's work documents their thinking and the details they note as they learn more. Over time, by drawing, dictating, or writing about their observations, children can reveal and deepen their understanding of science concepts. Documenting work to further understanding and sharing information is part of the National Science Education Teaching…

Explores the concept worksheet, which can help students identify and analyze important mathematical concepts and is a simple assignment that can be completed by students overnight. Four types of exercises are included: definition, web of attributes, examples, and nonexamples. (MKR)

Cites results of studies showing that students' language skills are not deteriorating. Suggests using class time for writing workshops to give students feedback on work-in-progress. Considers that difficulty with concepts and subject content may come across as poor writing. Notes that additional writing can be helpful without being graded. (DK)

Presents class activities to facilitate concept acquisition in elementary social studies classes. Suggests ways to teach the concepts of family, city, the presidency, and immigration. Methods outlined include field trips, oral history projects, family shield design, letters to past U.S. Presidents, fact quizzes, art activities, and guest speakers.…

Discussed is the importance of students being able to read and understand mathematics. The need for students to practice reading mathematics is emphasized. Discussions and homework are presented as examples of this needed practice. (KR)

Presents a lesson plan that uses subordinating conjunctions and prepositions as "magic words." After a lesson or unit of study, students write content specific sentences using the "magic" conjunctions and prepositions. This activity serves as a unit review, helps with concept formation, and increases writing skills. (MJP)

This book is a collection of essays by full-time classroom teachers who describe their efforts to implement the vision of the National Council of Teachers of Mathematics Standards documents and to empower their students in mathematics. Chapter 1, "Students' Conceptions of Mathematics and the Challenge of the Standards" (Dorothy Buerk),…
