Comprehension tests in mathematics

An alternative way for testing a student's understanding of theory in a tertiary mathematics course is presented. Two sample questions are provided and advantages and disadvantages of the method are discussed. We argue that the method is an acceptable and flexible means of testing students, and can be adapted to be used in other contexts as well. This revised version was published online in July 2006 with corrections to the Cover Date.     

Characteristics of Children with Moderate Mathematics Deficiencies: A Longitudinal Perspective

The reading and mathematics achievement and specific mathematical competencies of 74 children were followed over four time points during second and third grades. At the beginning of the study, children were classified into one of four groups: moderate mathematics deficiencies but normal reading (MMD‐only); moderate mathematics and reading deficiencies (MMD/MRD); moderate reading deficiencies but normal mathematics (MRD‐only); and normal achievement in reading and mathematics (NA). Although the MMD‐only and the MMD/MRD groups started out at the same level in mathematics, the MMD‐only group surpassed the MMD/MRD group over time. A parallel pattern in reading was not observed for the MRD‐only and MMD/MRD groups, with children in both groups performing at consistently low levels. Weaknesses in fact retrieval and estimation characterized children with MMD, with or without RD. The MMD‐only group showed an advantage over the MMD/MRD group in problem solving. Reading and language strengths help children compensate for deficiencies in selected areas of mathematics.     

Acute citrulline-malate supplementation improves maximal strength and anaerobic power in female,masters athletes tennis players

Citrulline-malate (CM) is a precursor to nitric-oxide (NO) in the NO synthase (NOS) pathway and is suggested to increase exercise performance in younger individuals. With age, NO production decreases and augmented NO production may provide beneficial effects on sports performance among masters athletes (MAs). Purpose: To examine the effects of acute CM supplementation on grip strength, vertical power, and anaerobic cycling performance in female, MA tennis players. Methods: Seventeen female MA (51?±?9 years) completed two double-blind, randomized trials consuming CM (12?g dextrose?+?8?g CM) and placebo (PLA) (12?g dextrose). One hour after consumption, subjects completed grip strength, vertical power, and Wingate anaerobic cycling assessments in respective order. Maximal and average grip strength, peak and average vertical power, anaerobic capacity, peak power, explosive power, and ability to sustain anaerobic power were calculated from the tests. Results: When consuming CM, participants exhibited greater maximal (p?=?.042) and average (p?=?.045) grip strength compared to PLA. No differences existed between trials for peak (p?=?.51) or average (p?=?.51) vertical power. For the Wingate, peak power (p?p?p?Conclusions: These data suggest that consuming CM before competition has the potential to improve tennis match-play performance in masters tennis athletes. However, this study utilized a controlled laboratory environment and research evaluating direct application to on-court performance is warranted.     

The ABCs of private equity and venture capital data and information

ABSTRACT

In June 2017, the Business Reference & Services Section of the Reference & User Services Association organized and hosted an event known as the Publishers' Forum during the annual American Library Association Conference in Chicago, Illinois. The Publishers' Forum is a professional development event that brings together business librarians and publishers of business information to engage in a discussion about business information products. The theme of the 2017 Publishers' Forum was private equity and venture capital data and information, and three different publishers were invited to speak and showcase their information products. This article will provide an overview of the Publishers' Forum, discuss the selection of private equity and venture capital as the theme, and highlight the importance of private equity and venture capital to business librarianship. Finally, this article will include a discussion of each of the publishers who presented at the Publishers' Forum and the information products they showcased.     

Seeking Emergence Through Temporal Analysis of Collaborative-Group Discourse: A Complex-Systems Approach

Abstract

Research around problem solving in collaborative groups has made progress, but several conceptual and methodological issues remain. These issues include the appropriate choices of units of analysis; the ability of current theoretical sets of macrocognition codes to capture group dynamics; detection and identification of potentially emergent phenomena within groups; and the extent to which multiple dynamics are integral to understanding groups. Using data from a complex engineering challenge, we applied methods drawn from complex-systems analysis to offer insight into each of these issues, showing the need for multiple dimensions when studying group dynamics and highlighting methodological difficulties when dealing with emergent phenomena. We suggest future research to improve the understanding of the complex dynamics of collaborative groups.     

True-False Testing on Trial: Guilty as Charged or Falsely Accused?

Although widely used, the true-false test is often regarded as a superficial or even harmful test, one that lacks the pedagogical efficacy of more substantive tests (e.g., cued-recall or short-answer tests). Such charges, however, lack conclusive evidence and may, in some cases, be false. Across four experiments, we investigated how true-false testing of studied passages (e.g., on Yellowstone National Park) might enhance—or be optimized to enhance—performance on subsequent cued-recall tests. In Experiments 1–2, relative to control performance that did not benefit from any additional exposure, we found that (a) the evaluation of true statements enhanced the recall of tested (but not related) content and that (b) the evaluation of false statements enhanced the recall of related (but not tested) content, a differential pattern of benefits that did not depend on the syntactic structure of the test items. Moreover, when competitive clauses were embedded within the true-false items of Experiment 3 (e.g., True or false? Castle Geyser (not Steamboat Geyser) is the tallest geyser), we found that the evaluation of both types of statements enhanced the recall of both types of content. Finally, in Experiment 4, these holistic benefits proved robust to a retention interval of 48 h and were comparable with the benefits of a restudy condition in which learners restudied all of the propositions that could have been retrieved in the evaluation of the true-false items. Accordingly, although it was not uncommon for participants to misremember information as a consequence of true-false practice, our findings broadly indicate that, especially when carefully constructed, true-false tests can elicit beneficial, not superficial, processes that belie their poor reputation.

     

An assessment matrix for library makerspaces

The emergence of maker culture has led to an increase of makerspaces across a variety of educational organizations, including public libraries. These makerspaces provide library patrons with new opportunities to learn and create through exploration, creation, and play. However, as the number of library makerspaces grows, so does the need for assessing learning in those same spaces. There is a small amount of research completed on assessing learning of makerspaces in public libraries. The researchers in this study examine patron use of a library makerspace through a theoretical framework based on modern assessment research. Soon after the study began, it was necessary to rethink the original research questions and methods in order to better understand how assessment could be effectively implemented. Findings include determining the scope of library makerspace participants and their assessment needs, potential assessments that can address those needs, and design implications for assessments in library makerspaces.     

Die Umwegrentabilit?t einer Hochschule am Beispiel der FH JOANNEUM Campus Kapfenberg

Hochschulen verursachen nicht nur Kosten, sondern generieren auch einen erheblichen Nutzen, da sie Geld- und Güterstr?me zwischen der ?ffentlichen Hand, Privatpersonen und Unternehmen in Gang setzen. Daraus resultieren tangible (in Geldwerten messbare) und intangible (nicht in Geldwerten messbare) Effekte, die durch den Betrieb einer Hochschule entstehen. Diese Auswirkungen wurden für den Standort Kapfenberg der FH JOANNEUM erhoben. Aus der durchgeführten Analyse ergeben sich folgende Effekte: aus kurzfristiger Sichtweise flie?en j?hrlich fast 3,0 Mio. € der Region Bruck/Mur-Kapfenberg zu, der mittelfristig in der Region verbleibende Kaufkraftanteil betr?gt über 2,0 Mio. € und aus langfristiger Perspektive werden durch das Bestehen der FH JOANNEUM Campus Kapfenberg fast 3,6 Mio. € an zus?tzlichem Einkommen in der Region Bruck/Mur-Kapfenberg induziert. Daneben entstehen durch die Existenz einer Hochschule auch noch positive Effekte für eine Region, die nicht eindeutig quantifizierbar sind.
