Under the new ABET accreditation framework, students are expected to demonstrate "an ability to develop and conduct appropriate experimentation, analyze and interpret data, and use engineering judgment to draw conclusions." Traditional, recipe-based labs provide few opportunities for students to engage in realistic experimental design or…

The main objective of the study was to determine Pre-service Chemistry Teachers' (PCTs) understanding of isomerism related concepts of Aliphatic Hydrocarbons (AHs). To get in-depth picture of PCTs understanding on isomerism related concepts of AHs, case study was employed. The sample for this study consisted of twelve participants selected from 87…

The preponderance of visually oriented and visually complex concepts and information in science classrooms poses significant challenges to learning among students with visual impairment (VI). It is acknowledged that the good quality of practical work promotes the engagement and interest and curiosity of students as well as developing a range of…

Instructional materials are an important resource in US classrooms. They represent the intersection of standards, subject matter knowledge and practice, and pedagogy. In light of the Framework for K-12 Science Education (National Research Council, 2012) and the subsequently released Next Generation Science Standards (Next Generation Science…

Biological materials oversight in life sciences research in the United States is a challenging endeavor for institutions and the scientific, regulatory compliance, and federal communities. In order to assess biological materials oversight at Institutional Biosafety Committees (IBCs) registered with the United States National Institutes of Health,…

Previous research has identified various factors that contribute to readers' comprehension of expository texts, including strategy expertise, language proficiency, prior knowledge, and more recently, readers' beliefs about knowledge. This study addresses the need to understand the relative contributions of these predictors to readers'…

This qualitative case study examines the initial implementation of a problem-based version of an undergraduate course in materials science for the purpose of identifying areas of improvement to the curriculum prior to a planned second implementation. The course was designed around problems that students work in small teams to solve under the…

Compared is the mass of a dozen eggs with the mass of air in an empty refrigerator. An answer and reasons for the answer are provided. (YP)

This instrument contains activities by which one can determine a child's intellectual development in: (1) observing, (2) classifying, (3) measuring, (4) using numbers, (5) using space/time relationships, (6) inferring, and (7) communicating and predicting. The seven sections of the instrument correspond to those processes defined in Science - A…

This booklet, compiled by the Ontario Institute for Studies in Education, lists behavioral objectives for biology in grades 4-6. The major areas of biology objectives presented are relations among plants, animals, and the environment; identifying and classifying plants and animals; and structures and functions of plants and animals. Each major…

Describes a paper-and-pencil test for high school biology students measuring science process skills, such as developing hypotheses; making predictions; identifying assumptions; analyzing data; and formulating conclusions. Reports some data on reliability and validity of the test. Provides all 35 items of the test. (YP)

This study was designed to identify students' misconceptions concerning frictional force, and Newton's laws of motion. It was also designed to determine the effectiveness of using instructions based on students' misconceptions to improve the teaching of physics. A pencil-and-paper test was administered to three groups of 16-year-old students:…

Refutes 14 items from "Computer Test Bank for Heath Physical Science." Discusses the correct answers item by item. (YP)

This is the teacher's guide to a student text designed to help users understand: (1) what groundwater is and how it is part of the hydrologic cycle; (2) how groundwater travels; (3) how groundwater is stored, purified, or contaminated; (4) the five physiographic regions in Virginia that store groundwater; and (5) the everyday activities that help…

This science test was intended for administration during June, 1989. It contains 75 multiple-choice questions. Ninety minutes are allowed for completing the test. No answer key is included since scoring is done by the provincial education department. The test is provided in both English and French. (YP)
