This study aims to develop an indigenous science instructional model. The samples were divided into two groups. Firstly, 24 experts for designing an indigenous science instructional model using Delphi Technique. Secondly, three classrooms of Mathayomsuksa 3 students for developing an instructional model. The findings revealed that Delphi technique…

A simple, guided-inquiry investigation using stacked sandwich cookies is employed to develop a simple linear mathematical model and to explore measurement error by incorporating errors as part of the investigation. Both random and systematic errors are presented. The model and errors are then investigated further by engaging with an interactive…

The Child Development & Behavior (CDB) Branch of the National Institute of Child Health and Human Development (NICHD) seeks to improve the health and well-being of individuals from infancy through early adulthood by supporting research into healthy growth and development, including all aspects of child development. The study of typical child…

Indonesian primary school children are taught to memorize science facts and learn only routine skills. School science lessons focus on low-order thinking as required on the frequent district formative tests and a national year six examination. Because of this emphasis on testing, students show little interest in asking questions about everyday…

This document provides practical suggestions and meaningful activities for implementing Ohio's model curriculum in science for instruction that emphasizes hands-on experience and diverse learning opportunities. It also includes a variety of nonscience activities that emphasize and utilize the outdoors. This Sampler lists activities by indoor or…

This book contains innovative hands-on science laboratory activities that teach basic scientific method skills and are designed to be used directly with 4th- through 9th-grade students. The background materials and instructions included in each activity are written for students to work together in teams. Lab titles are: observation lab,…

In a world where science has become too confined to books and too reliant on technology, and science fairs have been taken over by parents, this paper offers suggestions to help young people have actual hands-on experience with nature. Topics include soil formation; ants; earthworms; temperature; weather predictions; rain acidity; physical science…

The study reported in this paper combined qualitative (observation, interview and case study techniques) and quantitative (questionnaire and survey instruments) methods to examine: (1) the relationship of current teaching practices to a number of variables that affected students' learning in science laboratory classrooms, (2) which factors…

This paper reports on a study involving the development and application of an instrument to identify and measure ill-structured problem formulation and resolution (PFR) in online asynchronous discussions (OADs). The instrument was developed by first determining PFR processes relevant to ill-structured problems in professional practice. The…

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…
