Learning analytics, referring to the measurement, collection, analysis, and reporting of data about learners and their contexts in order to optimize learning and the environments in which it occurs, is proving to be a powerful approach for understanding and improving science learning. However, few studies focused on leveraging learning analytics…

This is part two of a series. It covers industrial vapor explosions and gives case histories of water-molten metal explosions. (BB)

Describes the construction and application of a device small enough to be worn on a worker's clothing that can monitor exposure to mercury. (MLH)

This report contains five action research papers in science education. Papers include: (1) "Does Classroom Size in an Industrial Technology Laboratory Affect Grades and Success in Class?" (Chad Bruns); (2) "The Effects of Project Based Learning on Students' Engagement, Independence, and Interest in Physical Geology Class" (Jill…

Analyzes the dangers of lasers in a classroom situation to formulate safety standards which are contrasted with federal regulations. Suggests that every laser user should check with the safety precautions to reduce the probability of producing a burn per student contact to extremely low levels. (CC)

Discusses the possible dangers of the educational radioactive sources used in a college physics laboratory. The discussion is intended to increase the awareness of teachers and students. (HM)

This book is intended as a guide for people who are planning chemistry and physics research laboratories. It deals with the importance of effective communication between client and architect, the value of preliminary planning, and the role of the project officer. It also discusses the size and layout of individual laboratories, the design of…

Describes safety hazards encountered when placing squash balls into liquid nitrogen. Suggests using racquet balls, balloons, or economical Ping-Pong balls. (MVL)

Describes the experimental arrangement for x-ray analysis of samples which involves the following: the radioisotopic x-ray disk source; a student-built fluorescence chamber; the energy dispersive x-ray detector, linear amplifier and bias supply; and a multichannel pulse height analyzer. (GS)

Describes the construction and operational procedures of a simple setup which enables undergraduate students to conduct experiments on critical phenomena in gases. Indicates that the experimental features are proved comparable to those of the Reamer and Sage apparatus. (CC)

This booklet is made available by the National Science Teachers Association to provide district safety officers, school principals, science department heads, and secondary school science teachers with information on safety in schools, especially in science classrooms. The range of information includes Occupational Safety and Health Administration,…

Using hypothetical lawsuits as examples, the more common rules of law which define the acceptable conduct of a physics teacher in the classroom, laboratory, and general school area are examined. (BT)

An outdoor activity that demonstrates the Doppler effect is described. Class predictions are verified by actual involvement in collecting data. Presented is a method of analyzing data. Safety concerns are discussed. (KR)

This document is a report on a course in nuclear science for the high school curriculum. The course is designed to provide a basic but comprehensive understanding of the atom in the light of modern knowledge, and to show how people attempt to harness the tremendous energy liberated through fission and fusion reactions. The course crosses what are…
