The list of physiological events in which sex steroids play a role continues to increase. To decipher the roles that sex steroids play in any condition requires high quality cohorts of samples and assays that provide highly accurate quantitative measures. Liquid and gas chromatography coupled with mass spectrometry (LC-MS and GC-MS) have…

This paper is an examination of a teacher professional development program in northeast Louisiana, that provided 30 teachers and their students with the technology, skills, and content knowledge to collect data and explore weather trends. Data were collected from both continuous monitoring weather stations and simple school-based weather stations…

Accusport analyzers were used to generate lactate performance curves in an investigative laboratory activity emphasizing the importance of reliable instrumentation. Both the calibration and testing phases of the exercise provided students with a hands-on opportunity to use laboratory-grade instrumentation while allowing for meaningful connections…

A unifying modular approach to the description of modern instrumentation used in analytical measurements is described. Through the identification of five modules for analytical instrument, discussions pertaining to the different physical and chemical interactions can be better directed towards the similarities and differences in the actual methods.

This report is one of three publications from the task analysis study of ornamental horticulture conducted at Cornell University. It was designed to develop a procedural model for task analysis in the area of agribusiness. The personal interview method was used to collect data from businesses within nine identified areas of ornamental…

A method and apparatus for collecting and interpreting eye movement data is described that is both relatively inexpensive and portable. The study lists and describes hardware and software components of a data collection and data analysis system which provides precise information regarding the location, duration, and sequence of eye fixations while…

Infrared remote sensors, plus photometric interpretation and digital data analysis are being used to record the stresses on air, water, vegetation and soil. Directly recorded photographic information has been the most effective recording media for remote sensing. (BT)

Presented is a three-hour instrumental analysis experiment which allows study of software data-handling methods. These methods include sampling, boxcar averaging, smoothing, ensemble averaging, and digital filtering. Use of the program should provide students with a better idea of advantages and disadvantages of using such software data-handling…

The Student Behavior Analysis System is a simple, reliable instrument for evaluating student behaviors and providing feedback to teachers on the efficiency and quality of their instructional strategies. (MB)

Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (JN)

This book presents new ideas and approaches in research techniques in the areas of health, physical education, and recreation. Part 1, the introduction, includes two articles, which are "Why This Research?" by Arthur H. Steinhaus and "Overview of Research: Basic Principles" by Benjamin H. Massey. Part 2, discusses preparations…

The field test of using task data for recruitment of horticulture workers is the final phase of a larger task analysis study of the ornamental horticulture industry in New York State. The field test is designed to obtain a realistic assessment of the potential of task checklists for recruitment, including: (1) employer acceptance attitudes toward…

The author presents a brief statement giving reasons for followup studies of teacher problems and explains the procedure for conducting such studies, the instruments used for data collection, and the estimated costs of a follow-up program. The four reasons cited for investigating teacher problems are: (1) to expose teacher educators to current…

This packet of forms, instruments, and guidelines has been assembled to aid in the determination of the articulation status and needs existing in elementary-junior high school and junior-senior high school programs. The term "articulation" is understood to mean the smooth transition from one grade or subject area into the next with as little…

Without an efficient, effective data storage and retrieval system, no performance based teacher education assessment plan will succeed. Concepts and techniques fundamental to the establishment of such a system are described. (MJB)
