4NASA Technical Reports Server (NTRS) 20160006642: Relative Throughput Of The Near-IR Science Instruments For The James Webb Space Telescope As Measured During Ground Testing The Integrated Science Instrument Module

By

Data were obtained for the purpose of measuring the relative throughput of the Near-IR Science Instruments (SIs) of the James Webb Space Telescope (JWST) as part of the second and third cryogenic-vacuum tests (CV2CV3) of the Integrated Science Instrument Module (ISIM) conducted at the Goddard Space Flight Center (GSFC) in 2014 and 20152016, at the beginning and end of the environmental test program, respectively. This Poster focuses on data obtained as part of the Initial Optical Baseline and as part of the Final Performance test -- two epochs that roughly bracket the CV3 test. The purpose of the test is to trend relative throughput to monitor for any potential changes from gross problems such as contamination or degradation of an optical element. Point source data were taken at a variety of wavelengths for NIRCam Module A and Module B, NIRSpec, NIRISS, Guider 1 and Guider 2 using the Laser Diode (LD) 1.06 micron, LD 1.55 micron, 2.1 micron LED and 3.5 micron LED, as well as for NIRCam Mod A and B and NIRISS using a tungsten source and the F277W, and F480M filters. Spectra were taken using the G140M, G235M, and G395M gratings for NIRSpec, the GRISMR grism for NIRCam Mod A and B and the GR150C grism for NIRISS. The results of these measurements are compared to what would be expected given the efficiency of each of the optical elements in each SI. Although these data were taken as a check against gross problems, they can also be used to provide the first relative throughput estimate for each SI through the various filters source wavelengths measured in their flight-like configurations.

5NASA Technical Reports Server (NTRS) 20160003704: A Miniaturized Variable Pressure Scanning Electron Microscope (MVP-SEM) For The Surface Of Mars: An Instrument For The Planetary Science Community

By

The Miniaturized Variable Pressure Scanning Electron Microscope(MVP-SEM) project, funded by the NASA Planetary Instrument Concepts for the Advancement of Solar System Observations (PICASSO) Research Opportunities in Space and Earth Science (ROSES), will build upon previous miniaturized SEM designs for lunar and International Space Station (ISS) applications and recent advancements in variable pressure SEM's to design and build a SEM to complete analyses of samples on the surface of Mars using the atmosphere as an imaging medium. By the end of the PICASSO work, a prototype of the primary proof-of-concept components (i.e., the electron gun, focusing optics and scanning system)will be assembled and preliminary testing in a Mars analog chamber at the Jet Propulsion Laboratory will be completed to partially fulfill Technology Readiness Level to 5 requirements for those components. The team plans to have Secondary Electron Imaging(SEI), Backscattered Electron (BSE) detection, and Energy Dispersive Spectroscopy (EDS) capabilities through the MVP-SEM.

9NASA Technical Reports Server (NTRS) 19900017845: Applications Of ISES For Instrument Science

By

It is often the case that some instruments being used for geophysical measurements cannot measure some parameters that are important for processing the data obtained using the instrument. However, the parameters of interest may be measured by other instruments and these data made available to the operators of the first instrument. Processing the data immediately after it is acquired is useful in directing the operation of the same or different instrument or in providing a quick look data set to users on the ground. The four applications which are considered are: the decision to acquire data due to some important occurrence detected by Eos instruments; the decision not to acquire data at a scheduled time and/or location; the decision to acquire additional data to improve data quality; and combining data from several sources to enhance data quality. General examples are presented, which may or may not apply directly to Eos instruments on the various platforms.

By

The CheMin mineralogical instrument on MSL will return quantitative powder X-ray diffraction data (XRD) and qualitative X-ray fluorescence data (XRF; 14)Z)92) from scooped soil samples and drilled rock powders collected on the Mars surface. The geometry of the source, sample, and detector is shown. A transmission geometry was chosen so that diffracted intensities in the low-20 region (5-15 deg), important for phyllosilicate identification, could be detected.

12ERIC ED041843: The Instrument For The Analysis Of Science Teaching: A System For Measuring Teaching Behavior.

By

A system of interaction analysis, the Instrument for the Analysis of Science Teaching (IAST, Part 1), and an accompanying sign system (IAST, Part 2) were developed. Originally used to analyze teaching behavior observed in elementary school classrooms where "Science--A Process Approach" was being taught, IAST was later found to be applicable as a research tool and supervisory aid in other curriculum areas and at other levels. Part 1, a 26-category system based on the 10-category Flanders system, includes 10 student, 14 teacher, and two new categories. Data may be treated for the analysis of various tally records, graphs, ratios, matrices, and tactical findings. Part 2 is a 15-item check list designed to measure some of the characteristics considered to be important in teaching elementary science and "Science--A Process Approach" which could not be determined by part 1 alone. Training in using IAST entails approximately 12 hours of discussion and observation practice. Since the validity of the Scott coefficient PI, the customary statistic for calculating observer reliability, appears to decrease as the number of categories in a system increases, a standardized, nationally available recording of teaching behavior (the Suchman recording of an inquiry session available from Science Research Associates) was used in estimating reliability of observers, demonstrating the possibility of establishing a universal reference for estimates of observer reliability.

15ERIC ED366650: Factor Analysis Of The IDEA Student Rating Instrument For Introductory College Science And Mathematics Courses.

By

This study illustrates how a factor analysis of a well-designed student-rating instrument can increase its utility. Factor analysis of a student-rating instrument was used to reveal constructs that would explain student attrition in science, mathematics, and engineering majors. The Instructional Development and Effectiveness Assessment (IDEA) instrument is used to rate college courses in science or mathematics at Kansas State University. It is used to gather students' reactions to instructors, personal progress, and courses, as well as students' attitudes, and to obtain an overall rating. Subjects for the factor analysis were 141 upperclass students (56.7 percent male). The factor analysis reveals constructs about which students in science and mathematics have expressed concern. Of seven identified factors, the first three, interpreted as instructor presentation skills, student perception of personal progress, and student-teacher interaction, are particularly important in distinguishing instructor presentation from the personal aspects of course takers. Three tables present analysis results. (Contains 23 references.) (SLD)

16ERIC ED091188: The Effectiveness Of The Concept/Process Section Of The Assessment Instrument For The Science Curriculum Improvement Study First Grade Biological Science Unit Entitled "Organisms."

By

Eighty first-grade students, randomly selected from eight elementary schools, participated in this study. Four of the schools were located within the city and four in the rural area surrounding the city. The assessment instrument was the Organisms Evaluation Supplement, designed to evaluate students' attitudes in science, students' perception of the classroom environment, and how well students are achieving the specified cognitive objectives of the unit. The instrument was administered as a pretest and a posttest to all students. The treatment consisted of instructing the students in the "Organisms" unit of the Science Curriculum Improvement Study (SCIS) program. Significant positive change in pupil performance as a result of instruction was found. The gain scores were subjected to a t-test at the .05 level. No pretest or posttest differences were found when examining urban versus rural populations. It was concluded that the "Organisms" assessment instrument is effective in terms of content validity, reliability, objectivity and interest. (Author/EB)

18NASA Technical Reports Server (NTRS) 20060046733: Development And Sizing Of The JWST Integrated Science Instrument Module (ISIM) Metering Structure

By

The JWST Integrated Science Instrument Module (ISIM) includes a large metering structure (approx. 2m x 2m x 1.5m) that houses the science instruments and guider. Stringent dimensional stability and repeatability requirements combined with mass limitations led to the selection of a composite bonded frame design comprised of biased laminate tubes. Even with the superb material specific stiffness, achieving the required frequency for the given mass allocations in conjunction with severe spatial limitations imposed by the instrument complement has proven challenging. In response to the challenge, the ISIM structure team considered literally over 100 primary structure topology and kinematic mount configurations, and settled on a concept comprised of over 70 m of tubes, over 50 bonded joint assemblies, and a "split bi-pod" kinematic mount configuration. In this paper, we review the evolution of the ISIM primary structure topology and kinematic mount configuration to the current baseline concept.

19ERIC ED069155: A Study Of The Effects Of The Use Of A Pupil Response Instrument On The Behaviors Of Biological Science Teachers. Dinal Report.

By

Three separate, sequential three-month studies were made to determine the effects of timed pupil feedback on teaching behavior. Audiotapes were made of the teaching behaviors of eighteen teachers before, during, and after the teachers introduced a feedback instrument to their pupils. The tapes were analyzed for changes in teacher behavior over the period of time the feedback was used. The results indicated that student feedback did change the teaching behavior significantly. The general direction of change was toward less teacher talk and lecture. The questioning techniques of teachers stayed fairly constant with the only statistically significant change being in the mean number of questions asked each month. The conclusions were that students can give accurate feedback which effects change in teacher behavior and that this change can be described and quantified using interaction analysis techniques.

20ERIC ED139623: Development Of An Instrument To Measure Beliefs About Teaching Science.

By

An instrument was constructed to measure changes in teacher attitudes and beliefs resulting from training in the teaching of the Elementary Science Study (ESS) program. The 40-item, Likert type instrument was administered to a group of 22 elementary teachers attending a three-week National Science Foundation summer institute, on the first morning of their attendance and again on the last afternoon. Analyses of the data revealed that no items showed significant change in the non-preferred direction and that the means of 21 of the 40 items had changed significantly in the preferred direction. Of those items showing no significant change, most were high on the pretest. Analysis by subject revealed that 14 subjects showed significant change in the preferred direction, one showed significant change in the unpreferred direction, and seven subjects showed no significant change. The instrument developed is included in the document. (CS)

22ERIC ED282761: Predictive Validity Of GPA, CAT And NTE Science Specialty Tests On Scores Of A Performance Based Student Teaching Evaluation Instrument. Teacher Education Research Center Research Report No. 87-1.

By

The issues of teacher quality expressed by many of the recent national reports on excellence in education have led a number of universities and colleges to increase the admission requirements and/or the exit standards for teacher certification programs. Emphasis has been placed on higher grade point averages and demonstrated academic ability on national standardized tests, among which are the Professional Knowledge, General Knowledge, and discipline specific Specialty Tests of the National Teachers Examination. The purpose of this study was to examine some of the criteria currently used for admission or exit standards and to seek effective predictors for student teaching success. Specifically, this study attempts to determine whether grade point average (GPA), the California Achievement Test of Basic Skills--Total score (CAT-T), and the National Teachers Exams Specialty Tests for Chemistry, Physics and General Science and for Biology and General Science predict student teaching competence as measured by a performance-based assessment instrument. A number of studies have looked at GPA and standardized test scores, specifically those core exams of the National Teachers Examination, and have concluded standardized test scores and GPA are not effective predictors for teaching success. This study on NTE Science Specialty Exams confirms these findings, in that the NTE Science Specialty Exams showed little predictive capability of these measures of academic competence. It would seem that academic competence is just one of the important criteria in selecting teachers. (Author)

By

The persistent and prolonged pitiable state of teachers' job performance leading to poor academic achievement of secondary school students in Ebonyi State has become a source of concern and worry among stakeholders and parents. This could be that instructional supervision is not regularly performed by the principals in order to provide professional guidance and assistance to teachers to enable them improve on their instructional delivery. It therefore becomes necessary to investigate the relationship between principals supervisory techniques and teachers job performance in secondary schools in Ebonyi State. The study was guided by three research questions and three hypotheses were tested at 0.05 level of significance. The study adopted a correlation research design. The study population comprised 4,368 secondary school teachers in Ebonyi State. Stratified proportionate sampling technique was used to sample 1005 respondents from the population of the study. The researchers developed two sets of instruments titled "Principals' Supervisory Techniques Questionnaire (PSTQ)" and "Teachers Job Performance Questionnaire (TJPQ)" were used for data collection. The instrument was subjected to face and content validation by three experts who are lecturers; two in Department of Foundations and the other in Measurement and Evaluation Unit in the Department of Science Education, all from Faulty of Education, Ebonyi State University, Abakaliki. Cronbach alpha was employed for the reliability test and this yielded a coefficient of 0.78, 0.68 and 0.81 for the three parts of PSTQ and 0.78 for TJPQ respectively. Pearson product moment coefficient was used in answering the research questions and t-test was used in testing the hypotheses. The findings of the study revealed among others that there is a high positive correlation between classroom observation techniques and teachers' job performance in secondary schools in Ebonyi State. It also revealed that there was a significant relationship between principals' demonstration techniques and teachers' job performance in secondary schools in Ebonyi State. Based on the findings, conclusion was drawn and it was recommended among others that government should provide opportunity for principals to attend conferences, workshops, seminars and colloquiums on supervisory techniques at least once a year both nationally and internationally for more acquisition of skills and knowledge for effective instructional supervision in order to keep them at par with their foreign counterparts.

25GDC 2008: Troels Folmann - "The Art And Science Of Creating Your Own Instrument Samples"

BAFTA-award winning composer, Troels Folmann, will be describing a variety of custom sample techniques and tricks used in his latest TOMB RAIDER soundtracks and by the majority of A-listed composers in Hollywood. "The Art and Science of Creating Your Own Instrument Samples" involves a variety of exclusive recording, editing, programming and scoring techniques that are used to simulate full symphonic orchestras and choirs. The prime focus of this session is provide the audience with applicable knowledge in custom sample techniques for strings, brass, woodwinds, percussion and choirs - and provide an insight into the latest emerging trends within epic orchestral scoring. The custom sample techniques are meant to replace- and/or support commercial samples. The general difference between commercial sampling and custom sampling is based in technique. The commercial sample developers have a tendency to create clean- and studio polished samples, which have many great applications. However, in the simulation of something as complex as a symphonic orchestra you also need imprecision, power and emotive qualities in the samples, which is core of the custom sampling techniques.

32NASA Technical Reports Server (NTRS) 20120012554: Extreme Ultraviolet Variability Experiment (EVE) On The Solar Dynamics Observatory (SDO): Overview Of Science Objectives, Instrument Design, Data Products, And Model Developments

By

The highly variable solar extreme ultraviolet (EUV) radiation is the major energy input to the Earth's upper atmosphere, strongly impacting the geospace environment, affecting satellite operations, communications, and navigation. The Extreme ultraviolet Variability Experiment (EVE) onboard the NASA Solar Dynamics Observatory (SDO) will measure the solar EUV irradiance from 0.1 to 105 nm with unprecedented spectral resolution (0.1 nm), temporal cadence (ten seconds), and accuracy (20%). EVE includes several irradiance instruments: The Multiple EUV Grating Spectrographs (MEGS)-A is a grazingincidence spectrograph that measures the solar EUV irradiance in the 5 to 37 nm range with 0.1-nm resolution, and the MEGS-B is a normal-incidence, dual-pass spectrograph that measures the solar EUV irradiance in the 35 to 105 nm range with 0.1-nm resolution. To provide MEGS in-flight calibration, the EUV SpectroPhotometer (ESP) measures the solar EUV irradiance in broadbands between 0.1 and 39 nm, and a MEGS-Photometer measures the Sun s bright hydrogen emission at 121.6 nm. The EVE data products include a near real-time space-weather product (Level 0C), which provides the solar EUV irradiance in specific bands and also spectra in 0.1-nm intervals with a cadence of one minute and with a time delay of less than 15 minutes. The EVE higher-level products are Level 2 with the solar EUV irradiance at higher time cadence (0.25 seconds for photometers and ten seconds for spectrographs) and Level 3 with averages of the solar irradiance over a day and over each one-hour period. The EVE team also plans to advance existing models of solar EUV irradiance and to operationally use the EVE measurements in models of Earth s ionosphere and thermosphere. Improved understanding of the evolution of solar flares and extending the various models to incorporate solar flare events are high priorities for the EVE team.

By

In the spring of 1962, engineers from the Engineering Mechanics Division of the Jet Propulsion Laboratory gave a series of lectures on spacecraft design at the Engineering Design seminars conducted at the California Institute of Technology. Several of these lectures were subsequently given at Stanford University as part of the Space Technology seminar series sponsored by the Department of Aeronautics and Astronautics. Presented here are notes taken from these lectures. \n\nThe lectures were conceived with the intent of providing the audience with a glimpse of the activities of a few mechanical engineers who are involved in designing, building, and testing spacecraft. Engineering courses generally consist of heavily idealized problems in order to allow the more efficient teaching of mathematical technique. Students, therefore, receive a somewhat limited exposure to actual engineering problems, which are typified by more unknowns than equations. For this reason it was considered valuable to demonstrate some of the problems faced by spacecraft designers, the processes used to arrive at solutions, and the interactions between the engineer and the remainder of the organization in which he is constrained to operate. \n\nThese lecture notes are not so much a compilation of sophisticated techniques of analysis as they are a collection of examples of spacecraft hardware and associated problems. They will be of interest not so much to the experienced spacecraft designer as to those who wonder what part the mechanical engineer plays in an effort such as the exploration of space.

35ERIC ED406201: Development Of An Instrument To Measure Teacher Candidates' Attitudes And Beliefs About The Nature Of And The Teaching Of Mathematics And Science.

By

This paper describes the development of a valid and reliable instrument to measure teacher candidates' attitudes and beliefs about the nature of and the teaching of mathematics and science. The instrument--Attitudes and Beliefs about the Nature of an the Teaching of Mathematics and Science--was developed for the Maryland Collaborative for Teacher Preparation (MCTP), an undergraduate teacher preparation program for specialist mathematics and science elementary/middle level teachers funded by the National Science Foundation. Sections of the instrument that were verified by factor analysis dealt with beliefs about mathematics and science, attitudes toward mathematics and science, beliefs about teaching mathematics and science, attitudes toward learning to teach mathematics and science, and attitudes toward teaching mathematics and science. It is concluded that the survey instrument has proven useful as one tool in an effort to landscape the attitude and belief paths the MCTP teacher candidates travel during their undergraduate years. The survey instrument is included in the appendix. Contains 37 references. (Author/JRH)

39NASA Technical Reports Server (NTRS) 20140017075: Detection And Quantification Of Nitrogen Compounds In The First Drilled Martian Solid Samples By The Sample Analysis At Mars (SAM) Instrument Suite On The Mars Science Laboratory (MSL)

By

The Sample Analysis at Mars (SAM) instrument suite on the Mars Science Laboratory (MSL) Curiosity Rover detected both reduced and oxidized nitrogen-bearing compounds during the pyrolysis of surface materials at Yellowknife Bay in Gale Crater. Preliminary detections of nitrogen species include NO, HCN, ClCN, CH3CN, and TFMA (trifluoro-N-methyl-acetamide). Confirmation of indigenous Martian N-bearing compounds requires quantifying N contribution from the terrestrial derivatization reagents (e.g. N-methyl-N-tertbutyldimethylsilyltrifluoroacetamide, MTBSTFA and dimethylformamide, DMF) carried for SAM's wet chemistry experiment that contribute to the SAM background. Nitrogen species detected in the SAM solid sample analyses can also be produced during laboratory pyrolysis experiments where these reagents are heated in the presence of perchlorate, a compound that has also been identified by SAM in Mars solid samples.

43NASA Technical Reports Server (NTRS) 20100025442: Thermal Design Considerations Of The Hubble Space Telescope (HST) Science Instrument Control And Data Handler (SI C And DH-2)

By

Following a failure in side 1 of the HST SI C&DH in September 2008, HST Servicing Mission 4 (SM-4) was delayed so that a SI C&DH Orbital Replacement Unit (ORU) could be qualified for flight. This second generation SI C&DH (SI C&DH-2) included several enhancements which increased its thermal dissipation near critical components. In order to maintain the SI C&DH-2 within its operational temperature limits, several thermal modifications were installed prior to its final qualification testing. This paper presents the thermal modifications performed on the SI C&DH-2, as well as the thermal ground test results and a correlation of the SI C&DH-2 thermal design to flight telemetry.

44NASA Technical Reports Server (NTRS) 20110008098: Detection Limit Of Smectite By Chemin IV Laboratory Instrument: Preliminary Implications For Chemin On The Mars Science Laboratory Mission

By

The CheMin instrument on the Mars Science Laboratory (MSL) is an miniature X-ray diffraction (XRD) and X-ray fluorescence (XRF) instrument capable of detecting the mineralogical and elemental compositions of rocks, outcrops and soils on the surface of Mars. CheMin uses a microfocus-source Co X-ray tube, a transmission sample cell, and an energy-discriminating X-ray sensitive CCD to produce simultaneous 2-D XRD patterns and energy-dispersive X-ray histograms from powdered samples. CRISM and OMEGA have identified the presence of phyllosilicates at several locations on Mars including the four candidate MSL landing sites. The objective of this study was to conduct preliminary studies to determine the CheMin detection limit of smectite in a smectite/olivine mixed mineral system.

48NASA Technical Reports Server (NTRS) 20140010429: Detection Of Reduced Nitrogen Compounds At Rocknest Using The Sample Analysis At Mars (SAM) Instrument On The Mars Science Laboratory (MSL)

By

The Sample Analysis at Mars (SAM) instrument suite on the Mars Science Laboratory (MSL) Curiosity Rover detected nitrogen-bearing compounds during the pyrolysis of Rocknest material at Gale Crater. Hydrogen cyanide and acetonitrile were identified by the quadrupole mass spectrometer (QMS) both in direct evolved gas analysis (EGA). SAM carried out four separate analyses from Rocknest Scoop 5. A significant low temperature release was present in Rocknest runs 1-4, while a smaller high temperature release was also seen in Rocknest runs 1-3. Here we evaluate whether these compounds are indigenous to Mars or a pyrolysis product resulting from known terrestrial materials that are part of the SAM derivatization.

By

Calibration and testing of the instruments on the Integrated Science Instrument Module (ISIM) of the James Webb Space Telescope (JWST) is being performed by the use of a cryogenic, full-field, optical simulator that was constructed for this purpose. The Pupil Select Mechanism (PSM) assembly is one of several mechanisms and optical elements that compose the Optical Telescope Element SIMulator, or OSIM. The PSM allows for several optical elements to be inserted into the optical plane of OSIM, introducing a variety of aberrations, distortions, obscurations, and other calibration states into the pupil plane. The following discussion focuses on the details of the design evolution, analysis, build, and test of this mechanism along with the challenges associated with creating a sub arc-minute positioning mechanism operating in an extreme cryogenic environment. In addition, difficult challenges in the control system design will be discussed including the incorporation of closed-loop feedback control into a system that was designed to operate in an open-loop fashion.
