With each passing year, the public expects more of schools and teachers. Curricula become more complex, student populations become more diverse, responsibilities are added, and, except for resources, very little is taken away. Fundamentally, teachers are held responsible for everyone and everything that goes on in their classrooms, an awesome…

This study examined the writing strategies and text characteristics associated with discovering a scientific principle by writing about an experiment. Sixty-four university students (non-science majors) carried out a physics experiment concerning either buoyancy, or the forces acting on a balance scale, then wrote an informal journal-style note…

Diffusion and osmosis are central concepts in biology, both at the cellular and organ levels. They are presented several times throughout most introductory biology textbooks (e.g., Freeman, 2002), yet both processes are often difficult for students to understand (Odom, 1995; Zuckerman, 1994; Sanger "et al.", 2001; and results herein). Students…

Several studies support that stored memories undergo a new period of consolidation after retrieval. It is not known whether this process, termed reconsolidation, requires the same transcriptional mechanisms involved in consolidation. Increasing evidence supports the participation of the transcription factor NF-[Kappa]B in memory. This was…

The candle burning experiment is usually conducted in lower secondary classes to prove the (about) 20% oxygen in air. The aim of this paper is to show that teachers misinterpret the results of the experiment to satisfy the objectives of teaching this experiment. However, when the results of this experiment are interpreted correctly, the objectives…

As science teachers, they understand the importance of gaining student interest to promote learning. They know how challenging it is to spark the curiosity to truly engage students in the processes of "doing science." One often-used method of motivation is the demonstration of science in action. Demonstrations such as "discrepant events". They are…

Science and social studies have much to offer to all learners--including those with disabilities. However, instruction in these subjects has often been overlooked in the quest to better understand and improve leaning in English/language arts and mathematics. As we demonstrate in this paper, science and social studies help students attain skills,…

This manual is intended as a resource for teachers who have special education students in their mainstream science classes, for curriculum adoption committees, and for publishers and consumers of science curriculum materials. Part 1 describes general characteristics of students with disabilities and provides general mainstreaming strategies and…

Science process skills such as observing, classifying, inferring, interpreting, predicting, and hypothesizing can all be classified as a sub category of thinking skills. This book is part of the series "Strategies for Learning" that focuses on the step-by-step development and application of thinking skills as a vehicle for learning science. The…

Demonstration of chemical reactions is a tool used in the teaching of inorganic descriptive chemistry to enable students to understand the fundamental concepts of chemistry through the use of concrete examples. For maximum benefit, students need to learn through discovery to observe, interpret, hypothesize, and draw conclusions; however, chemical…

This document series has been established as part of Unesco's Science and Technology Programme to encourage an international exchange of ideas and information in science education. This volume addresses the improvement of biotechnology education in school up to year 10 and aims at improving the quantity and quality of biotechnology taught in…

This document is written to encourage college faculty to use a student-centered, activity-related, approach to science instruction. Suggestions are provided for methods that can be used by faculty and administrators to develop alternatives to lecturing. The major sections of this document include the following: (1) Is There an Alternative to…

These supplemental units contain four laboratory exercises that can be used to enhance the labs in "Physics for the Technologies." The four units (one mechanical, two thermal, and one electrical) are designed to enhance labs in presenting specific concepts. Each unit can be used as an example of how the concepts behind the theory apply…

This set of 16 laboratory activities is designed to illustrate the life cycle of Brassicae plants from seeds in pots to pods in 40 days. At certain points along the production cycle of the central core of labs, there are related lateral labs to provide additional learning opportunities employing this family of plants, referred to as "fast…

The study reported in the paper attempted to compare the science laboratory teaching practices and the learning environments of secondary schools in some developing and developed South Pacific countries. This study combined qualitative (observation, interview, and case study techniques) with quantitative methods. Analysis of data found similar…
