AbstractThe United Nations Office for Outer Space Affairs and the International Heliophysical Year (IHY) community have joined hands to deploy arrays of small, inexpensive instruments such as magnetometers, radio telescopes, GPS receivers, all-sky cameras, and particle detectors around the world to provide global measurements of ionospheric, magnetospheric and heliospheric phenomena. The small instrument programme is envisioned as a partnership between instrument providers, and instrument hosts in developing countries as one of United Nations Basic Space Science (UNBSS) activity. The lead scientist will provide the instruments (or fabrication plans for instruments) in the array; the host country will provide manpower, facilities, and operational support to obtain data with the instrument, located typically at a local university. This paper provides an overview of the IHY/UNBSS programme, its achievements and future plans.

A few years ago, I surprised my wife by asking for a guitar for Christmas. Our budget was limited in those days, so I started at the low-cost end and remember being disappointed with the tone quality of the guitar we purchased. Even with my poorly trained ear, I could tell the difference between a $50 guitar and a $100 instrument. The jump from $100 to $200 was also easily detectable. I could even make out the difference in tone quality between a $200 and a $500 guitar. One hand-crafted instrument with a $1000 price tag had a lovely tone. However, the limitations of my ear made it difficult to detect significant improvement in tone quality beyond that stage. At any rate, I realized that an instrument manufacturer would clearly not waste precious select woods on a “cigar-box” instrument. Since then, while trying to unlock the secrets of fine tone quality, the importance of materials in crafting fine musical instruments has become apparent during my investigations of various musical instruments in the laboratory.

Full textAbstract:
Increased understanding of the importance of the affective domain in chemistry education research has led to the development and adaptation of instruments to measure chemistry-specific affective traits, including motivation. Many of these instruments are adapted from other fields by using the word ‘chemistry’ in place of other disciplines or more general ‘science’ wording. Psychometric evidence is then provided for the functioning of the new adapted instrument. When an instrument is adapted from general language to specific (e.g.replacing ‘science’ with ‘chemistry’), an opportunity exists to compare the functioning of the original instrument in the same context as the adapted instrument. This information is important for understanding which types of modifications may have small or large impacts on instrument functioning and in which contexts these modifications may have more or less influence. In this study, data were collected from the online administration of scales from two science motivation instruments in chemistry courses for science majors and for non-science majors. Participants in each course were randomly assigned to view either the science version or chemistry version of the items. Response patterns indicated that students respond differently to different wordings of the items, with generally more favorable response to the science wording of items. Confirmatory factor analysis was used to investigate the internal structure of each instrument, however acceptable data-model fit was not obtained under any administration conditions. Additionally, no discernable pattern could be detected regarding the conditions showing better data-model fit. These results suggest that even seemingly small changes to item wording and administration context can affect instrument functioning, especially if the change in wording affects the construct measured by the instrument. This research further supports the need to provide psychometric evidence of instrument functioning each time an instrument is used and before any comparisons are made of responses to different versions of the instrument.

Abstract<title> SUMMARY </title>This paper is concerned with the relationship between scientific instruments and their corresponding science, and thus with the relationship between the studies of the history of instruments and the history of science. It discusses these relationships chiefly with reference to astronomy and related mathematical sciences in the period from about 1400 to 1650, but also suggests possible parellels in eighteenth- and nineteenth-century astronomy. On the basis of this analysis, it is suggested that the history of instruments, which at present is largely conceived as the history of instruments like those to be found in museums or private collections, is of most importance to those historians of science who are interested in exploring its social context.

Full textAbstract:
Biological small-angle neutron scattering (SANS) instruments facilitate critical analysis of the structure and dynamics of complex biological systems. However, with the growth of experimental demands and the advances in optical systems design, a new neutron optical concept is necessary to overcome the limitations of current instruments. This work presents an approach to include experimental objectives (i.e. the science to be supported by a specific neutron scattering instrument) in the optimization of the neutron optical concept. The approach for a proposed SANS instrument at the Second Target Station of the Spallation Neutron Source at Oak Ridge National Laboratory, USA, is presented here. The instrument is simulated with the McStas software package. The optimization process is driven by an evolutionary algorithm using McStas output data, which are processed to calculate an objective function designed to quantify the expected performance of the simulated neutron optical configuration for the intended purpose. Each McStas simulation covers the complete instrument, from source to detector, including realistic sample scattering functions. This approach effectively navigates a high-dimensional parameter space that is otherwise intractable; it allows the design of next-generation SANS instruments to address specific scientific cases and has the potential to increase instrument performance compared with traditional design approaches.

A new survey for measuring students’ astronomy and science attitudes that has been validated for use with high school students (with a future intent to expand to middle school and university) is presented. We initially present a short review of instruments in the literature that attempt to measure attitudes in astronomy together with the difficulties encountered in measuring these by researchers in the subsequent analyses of results. To illustrate this, we present an example from an Astro101-level university course to display the problems with the current, most commonly used, astronomy attitude instrument. We then present the initial design and the Factor Analysis of a new instrument designed to address the deficiencies of this existing instrument from a sample of students in a high school-level astronomy education project. The factors identified by this instrument include: Interest in Astronomy, Interest in Science Outside of School, Practical Work in Science, Teacher’s Actions in science, Perceptions of Ability in Science, Future Aspirations in Science, Benefits of Science, and Personal Relevance of School Science, all of which possess high internal response consistency and construct validity.

Abstract Line intensity mapping (LIM) is a new technique for tracing the global properties of galaxies over cosmic time. Detection of the very faint signals from redshifted carbon monoxide (CO), a tracer of star formation, pushes the limits of what is feasible with a total-power instrument. The CO Mapping Project Pathfinder is a first-generation instrument aiming to prove the concept and develop the technology for future experiments, as well as delivering early science products. With 19 receiver channels in a hexagonal focal plane arrangement on a 10.4 m antenna and an instantaneous 26–34 GHz frequency range with 2 MHz resolution, it is ideally suited to measuring CO (J = 1–0) from z ∼ 3. In this paper we discuss strategies for designing and building the Pathfinder and the challenges that were encountered. The design of the instrument prioritized LIM requirements over those of ancillary science. After a couple of years of operation, the instrument is well understood, and the first year of data is already yielding useful science results. Experience with this Pathfinder will guide the design of the next generations of experiments.

Kata Kunci: Pelatihan, Penyusunan, Instrumen, AKM ABSTRACT Minimum Competency Assessment is a minimum ability assessment carried out on students. The minimum ability in question is the most basic ability that must be possessed by students at a certain level, namely reading literacy and numeracy. AKM measures the thinking or reasoning competence of students when reading texts (literacy) and dealing with problems that require mathematical knowledge (numbering). Not all teachers have the knowledge and skills to compose instruments, for example, teachers at SMK Bina Kusuma Ruteng. Therefore, the community service team carried out training activities for the preparation of Minimum Competency Assessment instruments for teachers of SMK Bina Kusuma Ruteng. The training was conducted to develop teacher competence in compiling the AKM instrument to support the achievement of the expected learning objectives. The training activity was attended by 30 teachers of SMK Bina Kusuma Ruteng. This activity was carried out through several stages, namely interviews, planning, implementation, and evaluation. This activity can have a positive effect on the ability and skills of teachers in preparing the Minimum Competency Assessment instrument. Based on the results of data analysis, it was found that the quality of the training was in the very good category (4.75) and had an impact in the very good category (4.92). It is proven that the teachers can arrange the AKM instrument well. Meanwhile, the impact of the implementation of the training is in the very good category (4.82). It is proven that the teachers can arrange the AKM instrument well. Meanwhile, the impact of the implementation of the training is in the very good category (4.82).

Full textAbstract:
Existing survey instruments of trust in science and scientists that focus on the general public are potentially insufficient to assess climate skeptics’ perspectives towards climate science. They may miss important aspects of climate science about which skeptics raise concerns, and may not accurately measure climate skeptics’ distrust in climatology. We introduce a new survey instrument developed using data gathered from interviewing 33 self-identified climate change skeptics in Idaho. The survey items capture skeptics’ beliefs regarding climate scientists’ trustworthiness and credibility, their deference to scientific authority, and their perceptions of alienation from the climate science community. We validate our survey instrument using data from an online survey administered to 1000 residents in the U.S. Pacific Northwest who are skeptical of climate change. By employing standard survey design principles, we demonstrate how our new (dis)trust in climate science instrument performs in tandem with well-known predictors of science attitudes and pro-environmentalism.

Abstract
Objective – The objective of this review was to examine research instrument characteristics, and to examine the validity and reliability of research instruments developed by practicing librarians, which measure the construct of patron satisfaction with academic library reference services. The authors were also interested in the extent to which instruments could be reused
Methods – Authors searched three major library and information science databases: Library and Information Science Technology Abstracts (LISTA); Library Science Database (LD); and Library Literature & Information Science Index. Other databases searched were Current Nursing and Allied Health Literature (CINAHL); Education Resources Information Center (ERIC); Google Scholar; PubMed; and Web of Science. The authors identified studies of patron satisfaction with academic library reference services in which the researcher(s) developed an instrument to study the satisfaction construct. In this rapid-review study, the studies were from 2015 and 2016 only. All retrieved studies were examined for evidence of validity and reliability as primary indicators of instrument quality, and data was extracted for country of study, research design, mode of reference service, data collection method, types of questions, number of items related to satisfaction, and content of items representing the satisfaction construct. Instrument reusability was also determined.
Results – At the end of the screening stage of the review, a total of 29 instruments were examined. Nearly all studies were quantitative or mixed quantitative/qualitative in design. Twenty-six (90%) of the studies employed surveys alone to gather data. Twelve publications (41%) included a discussion of any type of validity; five (17%) included discussion of any type of reliability. Three articles (10%) demonstrated more than one type of validity evidence. Nine articles (31%) included the instrument in full in an appendix, and eight instruments (28%) were not appended but were described adequately so as to be reusable.
Conclusions – This review identified a range of quality in librarians’ research instruments for evaluating satisfaction with reference services. We encourage librarians to perform similar reviews to locate the highest-quality instrument on which to model their own, thereby increasing the rigor of Library and Information Science (LIS) research in general. This study shows that even a two-year rapid review is sufficient to locate a large quantity of research instruments to assist librarians in developing instruments.
