Device Comparability of Tablets and Computers for Assessment Purposes

The definition of what it means to take a test online continues to evolve with the inclusion of a broader range of item types and a wide array of devices used by students to access test content. To assure the validity and reliability of test scores for all students, device comparability research should be conducted to evaluate the impact of testing device on student test performance. The current study looked at the comparability of test scores across tablets and computers for high school students in three commonly assessed content areas and for a variety of different item types. Results indicate no statistically significant differences across device type for any content area or item type. Student survey results suggest that students may have a preference for taking tests on devices with which they have more experience, but that even limited exposure to tablets in this study increased positive responses for testing on tablets.     

Unvarnished Documentation: A Dialogue Between Teacher and Parent in Understanding a Child's “Bad” Behavior

Teachers are often asked to fill out progress reports that include check marks indicating if a child has met certain criteria. While this document offers a superficial glance at knowing a child, it is often the only kind of “assessment” a parent receives. The authors, a daycare teacher and a parent of Rosa, “the mean girl” in the daycare, show how the teacher's daily, unvarnished observations of Rosa and her daycare peers are written and shared publicly in a way that not only helps Rosa's mother gain profound new understandings of her daughter but also helps create a trusting community.     

An analysis of assignment completion and accuracy across time under fixed, variable, and extended token exchange periods in a classroom token economy

This research investigated the effects of employing fixed, variable, and extended token exchange periods for backups on the completion and quality of daily assignments of a total fifth- and sixth-grade class. The results indicated a higher percentage of assignments was completed when the number of days between point exchanges was variable, and that performance was maintained when the number of school days between point exchanges was gradually increased. The overall accuracy on assignments was high, but varying, and did not appear to be under the systematic control of the experimental procedures. Data for all pupils indicated that there were individual differences as to the effects of the various token (point) exchange procedures. Pupils with inconsistent assignment completion during Fixed Exchange Conditions (Fixed Period (FP-I, -II, -III) increased their assignment completion during the Variable Token Exchange Procedures (Variable Period (VP)-I, -II, -III). Thus, the variable sequencing of the number of days should be an important consideration in any effort to maintain the positive effects of token-reinforcement systems within classroom settings.     

Discovering Differences in the Nature of Verbal and Visual Messages

Objective: Students will identify several unique characteristics of verbal vs. visual messages, including the superior ability of language to communicate objective, factual, philosophical content in past, present, and future terms; and the superior ability of visual images to communicate social-emotional meaning and concrete information limited in time to the present

Courses: This activity could be useful in any class that includes units on the nature of verbal and nonverbal messages, such as a basic survey course, communication theory, media literacy, language and communication, and verbal and nonverbal communication

A version of this assignment was presented at the 2004 Central States Communication Association Convention, Cleveland, Ohio     

Differences among fastball,curveball, and change-up pitching biomechanics across various levels of baseball

Controversy continues whether curveballs are stressful for young baseball pitchers. Furthermore, it is unproven whether professional baseball pitchers have fewer kinematic differences between fastballs and off-speed pitches than lower level pitchers. Kinematic and kinetic data were measured for 111 healthy baseball pitchers (26 youth, 21 high school, 20 collegiate, 26 minor league, and 18 major league level) throwing fastballs, curveballs, and change-ups in an indoor biomechanics laboratory with a high-speed, automated digitising system. Differences between pitch types and between competition levels were analysed with repeated measures ANOVA. Shoulder and elbow kinetics were greater in fastballs than in change-ups, while curveball kinetics were not different from the other two types of pitches. Kinematic angles at the instant of ball release varied between pitch types, while kinematic angles at the instant of lead foot contact varied between competition levels. There were no significant interactions between pitch type and competition level, meaning that kinetic and kinematic differences between pitch types did not vary by competition level. Like previous investigations, this study did not support the theory that curveballs are relatively more stressful for young pitchers. Although pitchers desire consistent kinematics, there were differences between pitch types, independent of competition level.     

Life events,self‐concept,and adolescents' positive subjective well‐being

This study investigated the interrelationships among global self‐concept, life events, and positive subjective well‐being (positive affect [PA], negative affect [NA], and life satisfaction [LS]) in a sample of 92 high school students. The results demonstrated that life events contributed significant variance to predictions of PA, NA, and LS, over and above that of global self‐concept. Also, daily events contributed variance over and above that of major life events. Looking at the specific event types that related uniquely to the positive well‐being measures, only negative daily events related significantly to PA and NA, and only positive daily events related significantly to LS. The results also indicated that the positive well‐being constructs each contained unique variance and had different correlates, thus providing strong support for the multidimensionality of adolescent positive well‐being reports. Implications for further research and intervention programs are discussed. © 2000 John Wiley & Sons, Inc.     

The effects of baseball bat mass properties on swing mechanics,ground reaction forces,and swing timing

Swing trajectory and ground reaction forces (GRF) of 30 collegiate baseball batters hitting a pitched ball were compared between a standard bat, a bat with extra weight about its barrel, and a bat with extra weight in its handle. It was hypothesised that when compared to a standard bat, only a handle-weighted bat would produce equivalent bat kinematics. It was also hypothesised that hitters would not produce equivalent GRFs for each weighted bat, but would maintain equivalent timing when compared to a standard bat. Data were collected utilising a 500 Hz motion capture system and 1,000 Hz force plate system. Data between bats were considered equivalent when the 95% confidence interval of the difference was contained entirely within ±5% of the standard bat mean value. The handle-weighted bat had equivalent kinematics, whereas the barrel-weighted bat did not. Both weighted bats had equivalent peak GRF variables. Neither weighted bat maintained equivalence in the timing of bat kinematics and some peak GRFs. The ability to maintain swing kinematics with a handle-weighted bat may have implications for swing training and warm-up. However, altered timings of kinematics and kinetics require further research to understand the implications on returning to a conventionally weighted bat.     

Item-Level Comparative Analysis of Online and Paper Administrations of the Texas Assessment of Knowledge and Skills

This article describes a comparative study conducted at the item level for paper and online administrations of a statewide high stakes assessment. The goal was to identify characteristics of items that may have contributed to mode effects. Item-level analyses compared two modes of the Texas Assessment of Knowledge and Skills (TAKS) for up to four subjects at two grade levels. The analyses included significance tests of p-value differences, DIF, and response distributions for each item. Additional analyses investigated item position effects and objective-level mode differences. No evidence of item position effects emerged, but significant differences were found for several items and objectives in all subjects at grade 8 and in mathematics and English language arts (ELA) at grade 11. Differences generally favored the paper group. ELA items that were longer in passage length and math items that required graphing and geometric manipulations or involved scrolling in the online administration tended to be the items showing mode differences.     

ITALIAN PEOPLE AGED 50–75 YEARS ENROLLED IN A HEALTH PROMOTION PROGRAM: HEALTH AND LIFESTYLE

The article presents a quantitative and qualitative analysis that identifies the most important lifestyle factors of an independent population of 50-75 years living at home and in a variety of middle-sized towns in the Marche Region (Italy). The first step was an investigation of multiple associations among state of health, socioeconomic variables, and lifestyle. After studying the set of variables defining lifestyle, we proceeded to identify the most important ones in order to select a group of elderly with a "correct" lifestyle. The principal outcome concerns the overwhelming role played by the subjective perception of aging. It is, therefore, necessary for social policies to concentrate on the importance of promoting educational campaigns for the achievement of successful aging, stressing the value of both personal well-being and socializing activities.
