Child and Adolescent Use of Mobile Phones: An Unparalleled Complex Developmental Phenomenon

This article addresses why children's use of mobile phones is an unparalleled complex developmental phenomenon in hopes of providing a broad context for this special section. It first outlines mobile phones as a sophisticated personalized and multifunction technology. Then it presents mobile phone use by children as an unparalleled complex developmental phenomenon on the basis of its four behavioral elements, two mobile cultures, and two developmental processes. It further illustrates the existing knowledge about children's mobile phones use that has been accumulated over the past 23 years and highlights 12 most studied topics, especially distracted driving and radiation exposure. It concludes with three types of scientific contributions made by the 12 articles in the special section.     

The Reciprocal Links Between School Engagement,Youth Problem Behaviors,and School Dropout During Adolescence

Drawing on the self‐system model, this study conceptualized school engagement as a multidimensional construct, including behavioral, emotional, and cognitive engagement, and examined whether changes in the three types of school engagement related to changes in problem behaviors from 7th through 11th grades (approximately ages 12–17). In addition, a transactional model of reciprocal relations between school engagement and problem behaviors was tested to predict school dropout. Data were collected on 1,272 youth from an ethnically and economically diverse county (58% African American, 36% European American; 51% females). Results indicated that adolescents who had declines in behavioral and emotional engagement with school tended to have increased delinquency and substance use over time. There were bidirectional associations between behavioral and emotional engagement in school and youth problem behaviors over time. Finally, lower behavioral and emotional engagement and greater problem behaviors predicted greater likelihood of dropping out of school.     

Old Tricks Are the Best Tricks: Repurposing Programmed Instruction in the Mobile,Digital Age

This article describes an interesting mash‐up between programmed instruction and cloud‐based, mobile technology currently being used for learning retention and habit formation, both in enterprise settings and in the public. The technology is called Ringorang (ring‐o‐rang), and it delivers practical, incentive‐based education and behavioral impacts. It is an app for mobile and PC devices that produces tangible performance results by interweaving multiple components of behaviorism (and its derivatives) in a deceptively simple user experience: the app asks you a question and incentivizes you to answer. In some regards, it is a modern take on the teaching machine, with a few new tricks thrown in.     

Pre-service teachers’ acceptance of mobile-technology-supported learning activities

The purpose of this study was to develop a mobile learning acceptance model for pre-service teachers and to examine the relationships among technology acceptance factors. The literature on mobile learning acceptance lacks studies on pre-service teachers and studies that include concrete mobile learning scenarios. To overcome these problems, we have developed and implemented a mobile-technology-enabled information technology course. The data collection and analysis were conducted in two separate studies. First, we developed a mobile learning acceptance scale and applied confirmatory factor analysis with 408 participants. The final instrument included 28 items measuring eight technology acceptance factors, namely behavioral intention, attitude towards use, perceived usefulness, perceived ease of use, social influence, facilitating conditions, self-efficacy, and anxiety. After this, we collected a new set of data from 316 participants to examine the relationships among the factors using structural equation modeling. In both studies, we investigated the respective models’ invariance across gender and discipline groups, and both models fulfilled invariance requirements. The results indicated that perceived ease of use and social influence have direct effects on behavioral intention, whereas self-efficacy has an indirect effect. Depending on the group, the explained variance of behavioral intention ranged between 18.1% and 60.6%.

One‐to‐one mobile technology in high school physics classrooms: Understanding its use and outcome

This study examined ways in which high school students used mobile devices in physics classrooms and after school, and the impact of in‐class and after‐school mobile technology use on their physics learning performance and interest. We collected data from 803 high school freshmen in China after they had used mobile devices for over five months. A fixed‐effects model was employed to control the undetected variances. Results indicated that the students frequently used their mobile devices for physics learning in class and after school. Students also perceived the mobile devices as very useful for their physics learning, and their perception of usefulness was positively correlated with their frequency of use. Both the in‐class and after‐school duration and frequency of mobile technology use positively influenced students' physics learning achievement and interest. However, we also found that mobile technology was mainly used to augment rather than to transform instructional practices in physics classrooms. The paper concludes with a discussion of implications and limitations of these results for research and practice.     

University students' behavioral intention to use mobile learning: Evaluating the technology acceptance model

As many Korean universities have recommended the implementation of mobile learning (m‐learning) for various reasons, the number of such tertiary learning opportunities has steadily grown. However, little research has investigated the factors affecting university students' adoption and use of m‐learning. A sample of 288 Konkuk university students participated in the research. The process by which students adopt m‐learning was explained using structural equation modeling technique and the Linear Structural Relationship (LISREL) program. The general structural model based on the technology acceptance model included m‐learning self‐efficacy, relevance for students' major (MR), system accessibility, subjective norm (SN), perceived usefulness, perceived ease of use, attitude (AT), and behavioral intention to use m‐learning. The study results confirmed the acceptability of the model to explain students' acceptance of m‐learning. M‐learning AT was the most important construct in explaining the causal process in the model, followed by students' MR and SN.

Role of student engagement in the resilience of african american adolescents from low‐income rural communities

The study sought to determine whether behavioral and psychological engagement in middle school served a protective or promotive role, thereby contributing to the resilience of African American youth from low‐income rural communities. Teacher reports of adjustment (i.e., aggression, academic competence, popularity) in the sixth grade were gathered. Data on behavioral and psychological engagement across the seventh and eighth grade were collected from student self‐reports. In the ninth grade, achievement data were obtained from school grades and peer assessments measured aggression. To identify profiles across multiple behavioral measures that increase risk, early adjustment configurations were derived from sixth grade teacher reports. Regression analyses indicated that youth with Troubled, Tough, and Disengaged profiles were at risk for difficulties in subsequent achievement and/or aggression. In addition, behavioral and psychological engagement had a main effect relation with achievement and/or aggression, indicating that engagement served a promotive role. © 2011 Wiley Periodicals, Inc.     

M‐learning adequacy and perceptions of students and teachers in secondary schools

In recent years, the use of mobile technologies has increased in a number of fields such as banking, economy, tourism, entertainment, library research, etc. These developments have also led to the use of mobile technologies for educational purposes. The successful integration of mobile learning (m‐learning) technologies in education primarily demands that teachers' and students' adequacy and perceptions of such technology should be determined. Therefore, the aim of this study was to compare teachers' and students' abilities and perceptions concerning m‐learning. Research data for the analysis were obtained from a sample of 467 teachers and 1556 students from 32 schools that were surveyed in Northern Cyprus. Based on our results, we conclude that teachers and students want to use m‐learning in education. Their perceptions are positive but their m‐learning adequacy levels are not sufficient.     

The effects of developmental mentoring and high school mentors' attendance on their younger mentees' self‐esteem,social skills,and connectedness

Far more has been written about the possible outcomes of cross‐age mentoring than about actual outcomes and the processes that lead to change. This study examined the effect of mentors' attendance on their mentees' outcomes after six months of developmental mentoring. Developmental mentoring is a structured, cross‐age peer mentoring program designed to promote children's development by facilitating connectedness. In this randomized study of 73 Caucasian, rural youth, multiple analyses of covariance revealed that connectedness to school and parents at posttest were significantly greater for mentees than for the comparison group. Regression analyses revealed that changes in self‐esteem, social skills, and behavioral competence were highly related to mentors' attendance, suggesting relational processes accounted for more change than did exposure to program curricula. However, the relationship between mentors' inconsistent attendance and mentees' decline in self‐esteem and behavioral competence suggests that absent mentors may do more harm than good. © 2005 Wiley Periodicals, Inc.

Socio‐demographic factors relating to perception and use of mobile technologies in tertiary teaching

In 2014, we investigated how socio‐demographic factors such as gender, teaching disciplines, teaching experience and academic seniority were related to the perception and use of digital mobile technologies in learning and teaching of a group of university teachers from one research‐intensive university in New Zealand. Three hundred and eight teachers from this university completed an online questionnaire and 30 of them participated in a follow‐up interview. Survey results showed that while there was a strong positive correlation between using mobile technologies for personal learning and their use in teaching, only a small number of participants utilised mobile technologies in their learning and the vast majority also did not use these technologies in their teaching, More female teachers and humanities teachers used mobile devices and applications more frequently than male teachers and teachers from other academic disciplines. Also, female teachers had a more positive perception in learning and using mobile technologies. Junior teachers also tended to be more positive in technology use. While the overwhelming majority of the interview participants also perceived positive benefits of incorporating mobile devices and applications into their teaching, it was found that female teachers paid greater attention to pedagogy when considering mobile technology use and the lack of professional development limited their use in teaching.     

LD status and achievement: confounding variables in the study of children's social status, self-esteem, and behavioral functioning

The purpose of the present study was to examine the role of achievement in explaining the poor social and behavioral functioning associated with LD status, and to evaluate potential gender differences in patterns of interpersonal functioning among youth with learning disabilities (LD) and nondisabled (NLD) youth. Thirty-two students with learning disabilities (21 boys, 11 girls) were matched with same-sex, same-race classmates whose reading achievement was low (LA) or average (AA), and these groups were compared on peer ratings of liking and disliking, perceptions of self-worth and social acceptance, and teacher ratings of conduct problems, anxiety-withdrawal, and attention problems. Students with learning disabilities were less accepted and less well-liked than children in the LA or AA groups and also perceived their self-worth and social acceptance to be lower than LA or AA students. Group by Sex interactions were apparent for several of the peer rating and behavioral variables, indicating that different patterns of social and behavioral functioning distinguished LD boys and LD girls from their NLD peers. The findings highlight the potential role of low achievement in peers' dislike of LD girls and suggest the importance of investigating well-defined subgroups of youth with LD in future research.     

BEHAVIORAL INTENTION OF TEACHERS,SCHOOL PSYCHOLOGISTS,AND COUNSELORS TO INTERVENE AND PREVENT HARASSMENT OF LGBTQ YOUTH

A national sample of educators were surveyed to identity the attitudes, beliefs, school culture, and perceived barriers that would predict whether educators would intervene to stop bias and harassment directed at lesbian, gay, bisexual, transgendered, and questioning (LGBTQ) youth in schools. The survey questionnaire was organized according to the theory of planned behavior (TpB), a theoretical model linking attitudes to behavior. A sample of 968 teachers, school psychologists, and school counselors participated. Factor analysis indicated that the three TpB components (attitude, subjective norm, and perceived behavioral control) accurately predicted behavioral intention to advocate for LGBTQ youth. Path analysis supported the components of TpB in predicting behavioral intention, accounting for 21% of the variance. The path coefficients linking attitudes and subjective norm to behavioral intention were particularly robust and less so for perceived behavioral control. Implications for intervention and training of school personnel to improve advocacy for LGBTQ youth and reduce bias and harassment are discussed.     

Onset,development, and prevention of drinking and driving among adolescents

An etiological study was designed to investigate the onset and development of drinking and driving among adolescents who recently received their driver’s license. A theoretical framework, derived from Problem Behavior Theory, was applied in order to identify environmental, personality and behavioral factors associated with drinking and driving. Among students who reported that they had driven a motor vehicle in the past three months (N=1416), 33 percent of the males and 22 percent of the females (who averaged 16.7 years) reported “drinking at least two drinks on a single occasion prior to driving” at least once in the previous three months. Personality factors (including perceived ability to drive after drinking, tolerance of drinking and driving, and lack of self-confidence in avoiding drinking and driving situations), perceived environmental factors (perceived car availability and friends modelling of drinking and driving) and behavioral factors (riding with a drinking driver and marijuana use) accounted for a large proportion (49%) of the variance in reported drinking and driving. It is recommended that school-based, peer-led educational programs be designed which target young adolescents prior to the age at which legal driver license is obtained. The programs should be broad-based and consider drinking and driving within the larger context of drinking and driving related behaviors and traffic safety in general.     

Globalization,public policy,and ‘knowledge gap’: Ethiopian youth and the HIV/AIDS pandemic

Set against trans‐ or supra‐national policy initiatives which have framed the HIV/AIDS pandemic as in part a pedagogical issue, this paper critically explores local understandings of sexual practices (generally) as well as of HIV/AIDS (more specifically) among young people in the sub‐Saharan African country of Ethiopia. Ethiopia has the third largest number of HIV/AIDS infections in the world, behind only South Africa and India. Like many countries dealing with this pandemic, the Ethiopian government has articulated its response to a broader set of global presses, including those around information and education. Such responses, we will argue, are helpful but have important limitations. As this study shows, knowledge about safer sex practices and the dangers of HIV/AIDS are by now well known among many Ethiopian youth. Yet, this knowledge does not always effect behavioral change. Taking condom use as a key exemplar, we will look at how Ethiopian youth narrate their own sexual experiences, conduct, and practices. Deeply informed by the work of Pierre Bourdieu, we look to open new ‘thinking tools’ for a range of actors addressing this global pandemic in situated contexts. In particular, we challenge the ‘pedagogical subject’ – a subject lacking key information – interpolated into many of these policies. We highlight, instead, new disjunctures between emergent discourses around sex and sexuality as well as long‐standing, conservative attitudes toward gender.     

The relation between dimensions of maltreatment,placement instability,and mental health among youth in foster care

Youth in foster care with maltreatment experiences often demonstrate higher rates of mental and behavioral health problems compared to youth in the general population as well as maltreated youth who remain at home. Previous research has demonstrated that dimensions of maltreatment (type, frequency, and severity) and placement instability are two prominent factors that account for high rates of psychopathology (e.g., depression, anxiety, and disruptive behavior disorders). The present study sought to clarify the relation between maltreatment and mental health among youth in foster care by studying both the isolated dimensions of maltreatment and cumulative maltreatment, and to determine whether the effects of maltreatment on mental health operated indirectly through placement instability. Information on youth in foster care’s (N = 496, M_age = 13.14) mental and behavioral health, maltreatment history, and placement changes were obtained from state records and primary caregivers. Using a SEM framework, the results suggest that maltreatment and placement instability each independently relate to mental and behavioral health problems. Further, none of the maltreatment types predicted greater placement instability in the current models. These findings suggest that placement stability is critical for mental health for youth in foster care, regardless of the type, severity, or frequency of their maltreatment experiences. Results also indicated that, although cumulative maltreatment predicted both internalizing and externalizing symptoms, maltreatment frequency and severity had direct relations to externalizing symptoms only. These findings underscore the utility of comprehensive maltreatment assessment, encouraging researchers and clinicians to assess and carefully consider the relation between maltreatment dimensions and outcomes.     

The cross-cutting psychosocial and systemic barriers to holistic rehabilitation,including educational re-engagement,of incarcerated adolescents: Realities in and perspectives from Africa

The present study identifies the potential barriers to holistic rehabilitation, including educational re-engagement, of justice-involved youth in Africa. This was done using quantitative data on the educational and other psychosocial problems presented by a cohort of justice-involved youth and qualitative data on the realities on ground in the correctional school within a youth correctional facility in Lagos, Nigeria, as an illustrative example. Findings showed a lot of cross-cutting psycho-social and systemic barriers to holistic psycho-social rehabilitation of justice-involved adolescents. These include pre-existing psychosocial problems such as, educational disengagement prior to incarceration, high prevalence rates of untreated intercurrent behavioral disorders such as conduct disorders and attention-deficit/ hyperactivity disorder among detained youth, and lack of community- or school-based pre-emptive interventions for school-related indicators of delinquency within the juvenile justice system. Others are lack of non-incarcerating correctional system with focus on psychosocial and educational rehabilitation, poor standard of human/ infrastructural resource-capacity within the facilities, and low level of school-engagement occasioned by poor mental and behavioral health among those enrolled in correctional schools. Context-appropriate pre-emptive and responsive strategies to address cross-cutting psycho-social and rehabilitative needs of justice-involved youth were discussed.     

The Effectiveness of Mentoring Youth with Externalizing and Internalizing Behavioral Problems on Youth Outcomes and Parenting Stress: A Meta-analysis

Parents of children with significant externalizing and internalizing behavioral problems habitually report greater parenting stress compared to parents of children without these challenges. One avenue to alleviate parenting stress and ameliorate youth outcomes is youth mentoring, which includes a supportive adult paired with a child with the objective of engendering positive outcomes. The researcher sought to (a) evaluate the effectiveness of mentoring programs for children with significant externalizing and internalizing behavioral problems on parenting stress and youth outcomes and (b) explore moderator variables that may influence program effectiveness. Five studies were included in the current meta-analysis. Results revealed a small effect of these specialized mentoring programs on youth outcomes and parenting stress. Moderator analyses revealed program characteristics that enhance effectiveness. Mentoring programs that target children with significant behavioral and emotional problems may function as an additional service to improve youth outcomes and family functioning.     

Using 21st century video prompting technology to facilitate the independence of individuals with intellectual and developmental disabilities

Barriers in acquiring, maintaining, and generalizing daily living skills are factors that contribute to discrepancies in independent living outcomes among transition age youth and young adults with intellectual and developmental disabilities (IDD). Acquisition and generalization of daily living skills empowers transition age youth and young adults with disabilities to meet their own needs with minimal reliance on others. Infusing the use of technology as a self‐prompting device facilitates the acquisition of tasks that may not be otherwise attainable. In this study, self‐directed video prompting on an iPad with the My Pictures Talk application was used to help young adults with IDD in a postsecondary program acquire daily living skills in a single subject, multiple probe across subjects design. The effects of the intervention on generalization to tasks that were one, two, and three components different were also assessed. Results demonstrated a functional relationship between the introduction of the intervention and improvement in skill performance.
