The purpose of this study is to compare school readiness of children who had pre-school experiences and children without such experiences on the basis of scientific thinking skills. This comparison is held in terms of variables of age, gender, and socio economic status. The questions of the study in relation to the purpose of the study are as…

This science activity book, for grades 8-12, can be used to teach students the thinking skills they will need to undertake scientific exploration on their own. The skills they develop will improve their science abilities and enhance their overall academic performance. This book is divided into two sections: (1) "Dynamo Demos", teacher-led…

Assessment, when integrated with instruction, can provide a basis for restructuring science education. The National Science Education Standards are incorporated into this guide to assessing student understanding in science. Chapters include: (1) "Assessment Based on Six Domains of Science," which organizes an assessment framework for…

In this activity, students experiment and observe the similarities and differences between human-made objects and nature in small groups. Students compare the function and structure of hollow bones with drinking straws, bird beaks and tool pliers, and bat wings and airplane wings. A classroom discussion can be held to discuss similarities and…

In this activity, students learn about composite materials, tension as a force, and how they act on structural components through the design and testing of a strip of plastic chair webbing. This activity requires a 60-minute time period for completion. (Author/NB)

In their complex nature, early adolescents want to believe in their teachers. Teachers demonstrating what they believe earn respect from students. In science education, it is vital to link scientific phenomena to daily life and social decision making skills to engage students in developing science-process skills. The science-technology- society…

This paper argues for extending the definition of "technology" in education to include much more than just computers, and for recognizing the dangers of using technology for its entertainment purposes. Two conceptions of the proper use of technology in science classrooms are offered: (1) technology as tool; and (2) technology as topic. Specific…

Elementary teachers must make thousands of decisions about their teaching practices every day. From whom should they first seek a response? Who should be asked the next question? Will the students be in groups for this activity or do it alone? While many science educators have clear visions of strategies they should employ in science classrooms,…

Argues that in order to have bona fide inquiry experiences, students must formulate their own questions, create hypotheses, and design investigations that test those hypotheses and answer the proposed questions. (DDR)

Addresses the need for a good science program to teach students to integrate both the analytical and the creative pathways of inquiry. Also compares the specific functions of the brain's right (creative) and left (analytical) hemispheres as related to science. Suggests how to design a creative sense-gathering activity, and offers several sample…

Describes the new national biology curriculum in the Netherlands, including a modern branch of biology called ethology. Topics covered include General Objectives, Lessons on Ethology and Student Skills, Role of Ethological Theory in Lessons, Emphasis on Human Behavior, Student Skills to be Developed, and items to be included in lessons such as…

Identifies and describes the differences in the problem-solving methods used by faculty teaching introductory chemistry and students enrolled in an introductory chemistry course. Results indicate that students correctly solve algorithmic-mode problems more frequently. Contains 33 references. (DDR)

Details an activity in which students study physics concepts and principles of motion by observing sporting events. Specific examples, samples of finished projects, and a flipchart scoring rubric are included. (DKM)

Defines an exploratory lab as consisting of a series of hands-on, qualitative activities that are safe, simple, and inexpensive, use readily available supplies, and illustrate a concept being studied concurrently in the course. Summarizes the results of four years of testing the exploratory program. (DDR)

Describes a titrator system, constructed from a computer-interfaced pH-meter, that was designed to increase student involvement in the process. Combines automatic data collection with real-time graphical display and interactive controls to focus attention on the process rather than on bits of data. Improves understanding of concepts and…
