Applying Tablet‐Based Performance Support Application for Technicians’ Training at the Israeli Air Force: A Case Study

Performance support systems are mechanisms enabling users) productivity while reducing training expenses as support is being delivered in real time, often eliminating the need for costly pre‐performance training. Mobile technologies have created new opportunities for improved performance support systems, especially for tasks performed outside the offi ce. This article describes the fi rst mobile learning and performance support initiative taken by the Israeli Air Force. The project included the development and eff ectiveness pilot study of a learning and performance support application delivered via tablet to helicopter engine technicians. The application provided support videos and illustrations of maintenance routines, thereby enabling learning and practicing at the same time. Pilot study results show high performance levels of application users compared to those applying traditional methods. Results also show that self‐effi cacy levels were not aff ected by the successful performance achieved when using the mobile performance support application. Plans to expand mobile support use are also described.     

Being sloppy about slope: The effect of changing the scale

What is the slope of a(linear) function? Due to the ubiquitous use of mathematical software, this seemingly simple question is shown to lead to some subtle issues that are not usually addressed in the school curriculum. In particular, we present evidence that there exists much confusion regarding the connection between the algebraic and geometric aspects of slope, scale and angle. The confusion arises when some common but undeclared default assumptions, concerning the isomorphism between the algebraic and geometric systems, are undermined. The participants in the study were 11^th-grade students, prospective and in-service secondary mathematics teachers, mathematics educators and mathematicians — a total of 124 people. All participants responded to a simple but non-standard task, concerning the behavior of slope under a non-homogeneous change of scale. Analysis of the responses reveals two main approaches, which we have termed ‘analytic’ and ‘visual’, as well as some combinations of the two.     

Positive Experiences and Life Aspirations Among Adolescents With and Without Hearing Impairments

THE STUDY investigated the nature and intensity of positive experiences as well as the aspiration toward transpersonal commitments among 79 normally hearing and 42 hearing‐impaired adolescents, in order to achieve a better understanding of those factors in the experience of hearing‐impaired adolescents that have enriched and empowered their lives. Landsman's Positive Experience Questionnaire (PEQ) and Magen's Life Aspiration Questionnaire (LAQ) were utilized. No differences were found between normally hearing and hearing‐impaired adolescent groups regarding the intensity of their remembered positive experiences. In comparison with normally hearing adolescents, those with hearing impairments reported more positive interpersonal experiences, rarely experienced positive experiences “with self,” and showed less desire for transpersonal commitment, even with their hearing‐impaired peers. The role of the socialization process, with an emphasis on communication between the hearing‐impaired youngster and his and her environment, was discussed.     

Learning Using Dynamic and Static Visualizations: Students’ Comprehension, Prior Knowledge and Conceptual Status of a Biotechnological Method

The importance of biotechnology education at the high-school level has been recognized in a number of international curriculum frameworks around the world. One of the most problematic issues in learning biotechnology has been found to be the biotechnological methods involved. Here, we examine the unique contribution of an animation of the polymerase chain reaction (PCR) in promoting conceptual learning of the biotechnological method among 12th-grade biology majors. All of the students learned about the PCR using still images (n = 83) or the animation (n = 90). A significant advantage to the animation treatment was identified following learning. Students’ prior content knowledge was found to be an important factor for students who learned PCR using still images, serving as an obstacle to learning the PCR method in the case of low prior knowledge. Through analysing students’ discourse, using the framework of the conceptual status analysis, we found that students who learned about PCR using still images faced difficulties in understanding some mechanistic aspects of the method. On the other hand, using the animation gave the students an advantage in understanding those aspects.     

Studying Biotechnological Methods Using Animations: The Teacher’s Role

Animation has great potential for improving the way people learn. A number of studies in different scientific disciplines have shown that instruction involving computer animations can facilitate the understanding of processes at the molecular level. However, using animation alone does not ensure learning. Students sometimes miss essential features when they watch only animations, mainly due to the cognitive load involved. Moreover, students seem to attribute a great deal of authority to the computer and may develop misconceptions by taking animations of abstract concepts too literally. In this study, we attempted to explore teachers’ perceptions concerning the use of animations in the classroom while studying biotechnological methods, as well as the teachers’ contribution to the enactment of animations in class. Thirty high-school biotechnology teachers participated in a professional development workshop, aimed at investigating how teachers plan for and support learning with animation while studying biotechnological methods in class. From that sample, two teachers agreed to participate in two case studies aimed at characterizing teachers’ contribution to the enactment of animations in class while studying biotechnological methods. Our findings reveal marked teacher contribution in the following three aspects: establishing the “hands-on” point of view, helping students deal with the cognitive load that accompanies the use of animation, and implementing constructivist aspects of knowledge construction while studying using animations.     

Role Taking Ability,Nonverbal Sensitivity,Language and Social Adjustment of Deaf Adolecents

The relationships between social‐cognitive processes, language, and social‐behavioural skills were evaluated by analyzing the data of 68 deaf students, aged 14 to 2o years, who attended special education classes with vocational orientation. The social‐cognitive processes included Role Taking Ability (RTA) and Non‐Verbal Sensitivity (NVS). Language was evaluated by the Peabody Picture Vocabulary Test (PPVT) and by a test of Emotional Vocabulary (EV). Social‐behavioural skills were assessed by Goldstein, Sparfkin, Greshaw and Klein's (1980) Social Skills Checklist. The social‐behavioural skills were used as indicators of social adjustment. The results revealed low performance in all the social‐cognitive abilities. Language played a major role in social adjustment. However, the availability of specific emotional vocabulary was not a better predictor of social adjustment than general language ability. Although RTA was associated with social adjustment, this association was related to language ability, and RTA did not add a unique contribution to the explanation of social adjustment. NVS emerged as an important, special and independent social‐cognitive ability. The results were discussed in relation to the function of language in social cognition.     

Students’ writing and reading preferences in a paperless classroom

ABSTRACT

This study took place in a school which adopted a “paperless classroom” policy. The purpose of the study was to examine whether students who learn in a paperless classroom really prefer reading and writing on computers rather than on paper and whether their preferences differ according to contextual conditions and personal differences. The findings show that students’ reading and writing preferences depended on the context in which the reading or writing was performed. The boys preferred to read and write on the computer significantly more than girls. Conversely, the girls’ handwriting skills and preference for handwriting were higher than the boys’. Reading and writing on computer was found to be favored among strong students, while weak students tended to prefer using paper. This research also revealed a rapid decrease in favoring computer over paper in both reading and writing over time. Students who had experienced the paperless classroom policy in this school for three years were less supportive of the use of computers for reading and writing than younger students.     

Adolescents from disadvantaged neighborhoods: Personal characteristics as related to volunteer involvement

The purpose of the present study was to investigate the relationships between involvement in volunteer activities of youth from disadvantaged neighborhoods and their life aspirations: the intensity of their remembered positive experiences: and their sense of coherence (SOC). Scales measuring these factors were administered to three groups of adolescents from disadvantaged neighborhoods: a) 57 adolescents who had been active volunteers during the course of one year, b) 37 adolescents who had merely registered to become involved but had not yet begun their activity, and c) 42 adolescents who were not involved in any volunteer activity. A cross-sectional design was selected to compare the three groups. The results showed that adolescents who had been involved in such activities for a period of at least one year expressed a stronger sense of coherence in their lives, a higher desire to commit of themselves to society, and a greater capacity to experience more intense positive experiences, in comparison to the other two groups of their noninvolved peers. The potential significance of volunteer activity for disadvantated adolescents was explored, and suggestions were offered for new directions in social rehabilitation programs.The authors would like to thank Dee B.

FACTORS AFFECTING FEMALE TEACHERS’ ATTITUDES TOWARD HELP‐SEEKING OR HELP‐AVOIDANCE IN COPING WITH BEHAVIORAL PROBLEMS

Questionnaires were given to 392 elementary school teachers to examine help‐seeking or help‐avoidance in dealing with classroom behavioral problems. Scale validity was examined through a series of exploratory and confirmatory factor analyses. Using a series of multivariate regression analyses and structural equation modeling, we identified predictors of motivational goals, predictors of attitudes toward help‐seeking or help‐avoidance, and a model of teachers’ attitudes toward help‐seeking or help‐avoidance. Results revealed four types of attitudes. Two reflected a positive approach to seeking help, but for different reasons: the first is intended to end the confrontation rapidly, and the second strives to develop new coping abilities. Also, two avoidant behaviors intended to avoid seeking help were revealed: one from fear of failure, and the other from a desire to deal with the problems independently. These four positions support a model of teacher help‐seeking, where seeking or avoiding help arises from a combination of implicit theories, efficacy beliefs, and motivational goals. Suggestions for further research into motivational factors of teachers when seeking help in coping with behavioral problems are suggested, as well as a call for a renewed consideration of the effectiveness of teacher support mechanisms.
