Does the mode of delivery affect mathematics examination results?

At present most examinations are delivered on paper but there is a growing trend in many subjects to deliver some or part of these examinations by computer. It is therefore important to know whether there are any differences in the results obtained by candidates sitting examinations taken by computer compared with those obtained by candidates sitting conventional examinations using pen and paper. The purpose of this article is to describe the outcome of a pilot study designed to∗ investigate possible causes of any differences in results from the use of different modes of delivery in a mathematics examination. One outcome of this study was that the process of translating examination questions into a format required for use on the computer (but keeping this as a pen and paper test) can have a significant effect on examination results. However, the main conclusion is that changing the medium only has no effect on the results in mathematics examinations

Adaptation of a moral judgment interview for a pen and paper test

The purpose of the present study was to design and validate a written instrument which would approximate the Kohlberg (1958) Moral Judgment Interview in yielded scores. Validity of the instrument was determined by whether it yielded age differences in moral stage scores. Kohlberg found age differences and he later postulated a relationship between moral stages and cognitive stages which predicts age differences. The subjects were a non-random sampling of 57 seventh-grade students, 61 twelfth-grade students, and 50 college students. The data were collected, using two comparable written instruments, one of which was an open-end questionnaire requiring self-structured responses; the other was an objective multiple-choice instrument. Analyses of score differences within groups and between groups were done by the statistical procedures of analysis of variance and t>test for significance of the differences. The open-end Instrument discriminated the scores of seventh-graders and twelfth-graders, whereas the objective instrument did not discriminate among the three different groups at all

Study of KS semileptonic decays and CPT test with the KLOE detector

Study of semileptonic decays of neutral kaons allows to perform a test of discrete symmetries, as well as basic principles of the Standard Model. In this paper a general review on dependency between charge asymmetry constructed for semileptonic decays of short- and long-lived kaons and CPT symmetry is given. The current status of determination of charge asymmetry for short-lived kaon, obtained by reconstruction of about 10^5 KS -> pen decays collected at DAFNE with the KLOE detector is also reviewed.Comment: 4th Symposium on Prospects in the Physics of Discrete Symmetries (DISCRETE2014

PIERNIK mhd code - a multi-fluid, non-ideal extension of the relaxing-TVD scheme (I)

We present a new multi-fluid, grid MHD code PIERNIK, which is based on the Relaxing TVD scheme. The original scheme has been extended by an addition of dynamically independent, but interacting fluids: dust and a diffusive cosmic ray gas, described within the fluid approximation, with an option to add other fluids in an easy way. The code has been equipped with shearing-box boundary conditions, and a selfgravity module, Ohmic resistivity module, as well as other facilities which are useful in astrophysical fluid-dynamical simulations. The code is parallelized by means of the MPI library. In this paper we shortly introduce basic elements of the Relaxing TVD MHD algorithm, following Trac & Pen (2003) and Pen et al. (2003), and then focus on the conservative implementation of the shearing box model, constructed with the aid of the Masset's (2000) method. We present results of a test example of a formation of a gravitationally bounded object (planet) in a self-gravitating and differentially rotating fluid.Comment: 6 pages, 3 figures, conference proceedings of the Torun Exoplanets 200

PET LINER AS SOLUTION FOR INKJET PRINTER INK COMPATIBILITY ISSUE

Ink compatibility test is the assessment of the ability of a polymeric material to maintain its original properties after being exposed to an indicated chemical reagent environment for a specified period. It is a critical test that will be conducted by all the printer parts that will interact with inks, be it before the pen firing event in which inks are stored inside the ink tank, ink tube, ink cartridge or after the pen firing in which waste ink will spit onto spittoon and paper path platen ribs which act as full bleed printing overspray zone

How do interactive tabletop systems influence collaboration?

This paper examines some aspects of the usefulness of interactive tabletop systems, if and how these impact collaboration. We chose creative problem solving such as brainstorming as an application framework to test several collaborative media: the use of pen-and-paper tools, the ‘‘around-the-table’’ form factor, the digital tabletop interface, the attractiveness of interaction styles. Eighty subjects in total (20 groups of four members) participated in the experiments. The evaluation criteria were task performance, collaboration patterns (especially equity of contributions), and users’ subjective experience. The ‘‘aroundthe-table’’ form factor, which is hypothesized to promote social comparison, increased performance and improved collaboration through an increase of equity. Moreover, the attractiveness of the tabletop device improved subjective experience and increased motivation to engage in the task. However, designing attractiveness seems a highly challenging issue, since overly attractive interfaces may distract users from the task

Review on pen-and-paper-based observational methods for assessing ergonomic risk factors of computer work

Background: Computer works are associated with Musculoskeletal Disorders (MSDs). There are several methods have been developed to assess computer work risk factor related to MSDs. Objective: This review aims to give an overview of current techniques available for pen-and-paper-based observational methods in assessing ergonomic risk factors of computer work. Methods: We searched an electronic database for materials from 1992 until 2015. The selected methods were focused on computer work, pen-and-paper observational methods, office risk factors and musculoskeletal disorders. This review was developed to assess the risk factors, reliability and validity of pen-and-paper observational method associated with computer work. Two evaluators independently carried out this review. Results: Seven observational methods used to assess exposure to office risk factor for work-related musculoskeletal disorders were identified. The risk factors involved in current techniques of pen and paper based observational tools were postures, office components, force and repetition. From the seven methods, only five methods had been tested for reliability. They were proven to be reliable and were rated as moderate to good. For the validity testing, from seven methods only four methods were tested and the results are moderate. Conclusion: Many observational tools already exist, but no single tool appears to cover all of the risk factors including working posture, office component, force, repetition and office environment at office workstations and computer work. Although the most important factor in developing tool is proper validation of exposure assessment techniques, the existing observational method did not test reliability and validity. Futhermore, this review could provide the researchers with ways on how to improve the pen-and-paper-based observational method for assessing ergonomic risk factors of computer work

Imperatives of Computer Base Test (CBT) on Performance of LIS Students: A Case Study

Abstract The paper espouse the fact that paper pen test (PPT) is slowly replaced by computer base test (CBT) introduced over five decades ago in most tertiary institutions. It itemized the benefits and challenges of CBT. The focus is to assess the performance of students of LIS in a Nigerian university who pioneered the project. Factoring incorporated courses, necessity for the incorporation of CBT, influence of CBT on student performance and the challenges of CBT on these students performance anchored the thrust of the paper. The study was quantitative; questionnaire was used to collect data that is guided by the objective of the study. A total of 267 students participated. The study revealed that CBT incorporation is still at pilot level and that the pencil pen test stills prevails in the study area, however, since CBT incorporation, it has put to rest the claim that drudgery was one of the reasons for its utilization. Results show that its incorporation has encouraged students to be thorough and improve their technical skills. Challenges hinges on funding of the project, training of personnel and students must be prioritized for sustainability

A Comparison of Traditional Versus Computerized Anxiety Assessment Using Personal Digital Assistants

The usage of the personal computer has become more prevalent in the field of psychology. The advent of the Personal Digital Assistant (PDA) has opened a new area of possible clinical application. These pen-based devices allow for a more natural interface and more mobility. The feasibility and application of the PDA for personality assessment will be examined in this study. Does having a test administered by a PDA lead to a significant change in response patterns compared to a test administered by the traditional pen and paper method? The purpose of this study was to examine differences in the anxiety levels of light computer users and heavy computer users using a PDA. Eight volunteers were utilized for this study. Analyses revealed no significant differences between groups concerning state anxiety and trait anxiety
