Environmental identity,pro-environmental behaviors,and civic engagement of volunteer stewards in Portland area parks

We conducted surveys of adults participating in municipally sponsored volunteer events in the Portland, OR metropolitan area in order to understand the range of attitudes and behaviors associated with volunteer work. We sampled 172 individuals in 18 events from February to June 2012. Principal components and factor analyses of survey responses identified three groups based on annual frequency of participation in stewardship events: first-time volunteers, mid-level volunteers (3–10 events per year), and frequent volunteers (>10 events per year). Our analyses revealed three main factors that explained the variation in survey response for the three volunteer groups: environmental identity, private pro-environmental behavior, and civic engagement. All three factors were positively correlated with frequency of participation in stewardship events, with the most frequent volunteers indicating the highest degree of attention to environmental issues, environmental identity, and self-reported pro-environmental behaviors. Frequent volunteers were more likely to feel personally attached to their local environment, believe that their efforts help solve environmental problems, and enjoy being part of community efforts. These results suggest that stewardship activities provide opportunities for volunteers to interact with others while working collectively toward restoring and maintaining parks, which may contribute to more resilient communities.     

Children’s sexual behavior problems: An ecological model using the LONGSCAN data

BackgroundAlthough prior research has indicated that sexual behavior problems (SBPs) are present among maltreated and non-maltreated children, risk factors for SBPs remain understudied. Further, few studies have examined multiple forms of trauma such as exposure to community violence and several likely important familial and environmental factors have yet to be investigated in the context of SBPs. The use of a more comprehensive ecological model of child, trauma-related, family, and environmental risk factors may help to further delineate the factors that contribute to the development of SBPs.ObjectiveThe aim of the current study was to build upon previous research by utilizing an ecological model that includes child, trauma-related, caregiver and familial, and environmental factors as potential predictors of SBPs.Participants and SettingThe present study was conducted with 1,112 8-year-old children (51.6% female; 48.9% Black) and their primary caregivers from the Longitudinal Studies in Child Abuse and Neglect (LONGSCAN) study.ResultsSeveral child, caregiver, and familial factors, as well as sexual and physical abuse demonstrated bivariate associations with SBPs. A number of these factors remained significant in a regression model, such as child’s living arrangement, child’s aggressive behaviors and posttraumatic stress symptoms (PTSS), sexual and physical abuse, caregiver’s psychological difficulties, and children’s perceptions of family health.ConclusionsThe findings highlight the role of select child, trauma-related, caregiver and familial, and environmental factors in the context of SBPs and also demonstrate the need to examine multiple levels of children’s environments when investigating SBPs.     

Early life stress moderates the relationship between age and prosocial behaviors

BackgroundSeveral studies suggest that prosocial behaviors gradually increase with age, but others report that prosocial behaviors are fixed traits with only minor fluctuations throughout the lifespan. Early life stress may help explain these inconsistencies, as distinct types of stress have been negatively or positively associated with prosocial behaviors.ObjectiveThis current investigation used two studies to test whether distinct types of early life stress moderated the association between age and prosocial behavior.Participants and settingStudy 1 recruited undergraduate students (n = 69) between the ages of 18–35, and Study 2 was conducted on Amazon Mechanical Turk responders (n = 499) whose ages ranged from 18-74.MethodsStudy 1 employed behavioral economic tasks to measure cooperation and charitability, while Study 2 utilized an online survey to measure helping attitudes.ResultsModeration analyses revealed the association between age and cooperation was significantly weakened by a history of family violence (β=−0.37,p = 0.002), community violence (β=−0.30,p = 0.012), emotional abuse (β=−0.27,p = 0.026), and an overall summary score of early life stress (β=−0.33,p = 0.006). The relationship between age and charitability was only weakened by family violence (β=−0.24,p = 0.048). The association between age and helping attitudes was weakened by family violence (β=−0.10, p = 0.023), community violence (β=−0.13,p = 0.003), and physical neglect (β=−0.11,p = 0.018).ConclusionsCollectively, these results suggest that some types of early life stress, especially exposure to violent environments, may reduce the likelihood of prosocial behaviors increasing throughout the lifespan. This study suggests that age-related effects on prosocial behaviors may not be universal, but rather depend on individual differences in childhood stress.     

Computer-aided authoring of assessment instruments: An activity-theoretical approach

Abstract

Various researches have been conducted on the role and importance of assessment in education as well as its impact on the learner and the overall learning process. In fact, the way assessment is formulated in a particular subject shapes the way students learn. They focus their learning to comply with assessment requirements that they anticipate. In this article, the study is focused on the written examination papers (teacher-made tests) that are normally prepared at the end of a semester or an academic year to assess students of secondary and tertiary levels. The study also investigates how well papers are set and balanced according to the cognitive levels defined by Bloom (1956) and the learning outcomes/objectives as defined for the subjects. A collaborative process model as a framework for the design of such tests that can enhance the evaluation process is proposed. A brief argument is made for a case for a computer-supported collaborative environment to implement such a framework and which is based on activity theory. Such a framework is implemented in the form of MYSTIC; a collaborative authoring software for assessment instruments. The software allows stand-alone as well as collaborative authoring of examination papers and also helps academics' decision-making concerning the examination paper balancing and moderating process by graphically displaying and comparing marks allocated per question paper against the learning objectives

Test Anxiety Among Students Taking Semesterised and Traditional Courses

Abstract

A survey was conducted of the test anxiety of 154 second year students of a variety of subjects at a new British university. Half of the sample were studying on conventionally structured degree courses and half on newly semesterised degree courses. It was found that students on semesterised arts and science courses exhibited higher levels of test anxiety than did their counterparts on conventional courses but no such difference was observed for social science and business (including law) students. This finding is contrary to predictions based on a desensitisation model which would predict an attenuation of test anxiety as a result of more frequent testing under semesterised arrangements. A case is made that the character of assessment procedures, and possibly also students’ previous experience of the outcomes of assessment, contribute to an increase in test anxiety in the short to medium term. Any effects of desensitisation may only be evident in the longer term and may be opposed by other factors such as the timing of assessments under semesterised arrangements. Further research is required to fully investigate the long‐term effects of these variables.     

Pathways to delinquent and sex offending behavior: The role of childhood adversity and environmental context in a treatment sample of male adolescents

BackgroundExposure to greater Adverse Childhood Experiences (ACEs) has been associated with increased likelihood of general and sex offending behaviors. However, few studies consider both the impact of varied ACE exposures and other early experiences on pathways to offending behaviors in adolescents who have engaged in sexually abusive behaviors.ObjectiveThe purpose of this study was to examine the impact of ACEs and sexual boundary problems within the home on the development of delinquent and sexually abusive behavior.Participants & settingData were collected from archival records of male adolescents (N = 285) who had received treatment for sexually abusive behavior at a youth facility.MethodsThis study investigated the effects of individual adverse experiences on delinquent nonsexual and sexually abusive behaviors through structural equation modeling.ResultsStructural equation modeling revealed a three-factor model for ACEs. Direction and significance of paths between ACEs and the onset, persistence, and nature of maladaptive behaviors differed. Household dysfunction was related to an earlier onset (β = 1.19, p = 0.013) and more persistent nonsexual delinquent offending (β = 1.05, p = 0.048) and contact sexual offending (β = 1.19, p = 0.010). Conversely, sexual abuse and exposure to sexual boundary problems were associated with an earlier onset of sexually abusive behavior (β = −1.08, p = 0.038) as well as indicators of adolescent-onset (β = −1.30, p = 0.002), less persistent (β = −1.53, p = 0.001), and nonviolent (β = −1.89, p = 0.001) delinquency.ConclusionsFindings suggest variations in ACE exposures differentially influence the onset, severity, and persistence of delinquent and sexually abusive behaviors among these youths.     

DISTANCE TRAINING IN FUNCTION‐BASED INTERVENTIONS TO DECREASE STUDENT PROBLEM BEHAVIOR: SUMMARY OF 74 CASES FROM A UNIVERSITY COURSE

In this study, 188 master‐level students received training through a distance education course to conduct functional behavioral assessments (FBAs) and behavior support plans with 68 boys and six girls (aged 3–20 years) displaying persistent behavior problems in inclusive preschools, elementary, and secondary schools. In the course, master‐level students’ scores on an FBA knowledge test increased from 13.2% to 68.8% correct. Changes in pupils’ target behaviors were evaluated with a total of 114 AB single‐subject designs and combined data with one‐group pretest–posttest designs. Comparing medians of means, disruptive behaviors decreased by 77.8% and aggressive behaviors by 88.7%, whereas task engagement increased by 91.5% after intervention. Nonparametric Wilcoxon signed‐ranks tests for related samples showed that changes were statistically significant for all groups with sufficient sample sizes. Adjusted effect sizes ranged from d = .5 to 1.6. Results indicate that positive changes in student behavior problems can be attained with function‐based interventions conducted by teams trained through a distance education course.     

Teachers' perspectives on student problematic behavior and social skills

This study examined program outcomes of student problem behavior and social skills, based on teachers' perspectives, before and after early behavioral intervention services. The study targeted students in kindergarten through grade 5 who were identified by the school system as being at risk for emotional and behavioral disorders. Students identified received early intervention services based on individualized positive behavior supports (i.e. social skills training, functional behavioral assessment, and team collaboration). The results indicate that early intervention services that teach social skills and use functional behavioral assessments to deal with problem behaviors are beneficial to children displaying behavioral challenges.     

Effects of academic performance on the relationship between child maltreatment and deviant behavior: A national study in Taiwan

BackgroundChild maltreatment has been found to significantly increase the risk of deviant behavior. Academic performance has been shown to have an indirect effect on the relationship between child maltreatment and deviant behavior. However, not all adolescents who have been maltreated engage in deviant behavior, so the relationship between child maltreatment and deviant behavior has remained unclear.ObjectiveThe aim of this research was to examine the potential mediating and/or moderating effects of academic performance on the relationship between child maltreatment and deviant behavior.Participants and settingThe data in this study were from a nationwide study examining the consequences of childhood maltreatment in Taiwan. The database consisted of data from 2321 adolescents.MethodsA secondary data analysis was conducted. Self-report data were obtained on childhood maltreatment experiences, academic performance, and deviant behaviors. Path analyses and a generalized linear model were used to examine the effects of academic performance on the relationship between child maltreatment and deviant behavior.ResultsMost participants were male (61.4%), with a mean age of 15.9 years. The mean scores of self-rated academic performance and deviant behavior were 2.86 and 8.2, respectively. A total of 83% participants reported having experienced childhood maltreatment. In this study, academic performance was found to have a moderating rather than a mediating effect on the relationship between child maltreatment and deviant behavior. Among adolescents who had been maltreated during childhood, those who self-rated poorer academic performance were more likely to have a higher deviant behavior score than those who self-rated better academic performance.ConclusionsGood academic performance can be a buffer that reduces the risk of deviant behavior among individuals with a history of childhood maltreatment. Healthcare professionals and educators can tailor early prevention and intervention educational programs targeted toward adolescents with experience of childhood abuse or poor academic performance to prevent the incidence of deviant behavior and thus break the cycle of violence.

Development,Dissemination, and Assessment of a Food Safety Systems Management Curriculum for Agribusiness Students in Armenia

This study addresses the development, dissemination, and assessment of a Food Safety System Management (FSSM) curriculum offered to college‐aged, agribusiness students in Yerevan, Armenia. Prior to beginning the program, demographic data were collected and a paper‐based pretest was administered to access the food safety knowledge, behavior, and attitude of participants (n = 29). For assessment of a skill, participants’ handwashing techniques were videotaped and scored before the program commenced. Immediately after completion of the entire curriculum, a paper‐based post‐test with identical questions for food safety knowledge, behavior, and attitude was administered and handwashing skills were assessed. ANOVA with repeated measures was used to evaluate significant differences (α = 0.05) for food safety knowledge using a pretest, post‐test, and a 3‐mo follow‐up. A paired t‐test was used to evaluate handwashing skills before and after the curriculum was presented. The pretest score (44.93%, ± 2.87) for food safety knowledge (n = 29) differed significantly (P <0.0001) when compared with the post‐test score (73.21%, ± 3.28) and the 3‐mo follow‐up (n = 23) score (67.76%, ± 3.93). Participants’ (n = 9) handwashing skills prior to delivery of the FSSM curriculum differed significantly (P <0.0001), when compared to handwashing skills after completion of the curriculum. Students’ food safety attitudes and behavior assessed using a five‐point Likert scale, also improved significantly as a result of the FSSM program. The 3‐mo follow‐up survey on food safety attitude and behavior was consistent with the post‐test survey results. The information from this project may be of interest to education experts, Extension professionals, food industry personnel, or regulatory agencies, in the development and dissemination of an international food safety program.     

Factors associated with students’ attitude change in online peer assessment – a mixed methods study in a graduate-level course

Abstract

Positive student attitude towards peer assessment can be demonstrated through high-quality peer assessment activities. Research findings on students’ attitudes before and after such activities were mixed. This study was conducted using a mixed-methods approach to investigate the underlying factors influencing students’ attitude change. Participants were students enrolled in an online graduate-level assessment course in the college of education in a university in the southeast United States in the fall of 2017 (N?=?31). Surveys and interviews were used to collect quantitative and qualitative data separately, both of which indicated that perceived accurate and specific feedback tended to help students shift to more positive attitudes towards online peer assessment. In addition, final task score improvement after the activity was correlated with positive attitude change. Qualitative results also identified other factors, such as communication with the peers’ work and logistic concerns. The current study offers insights for researchers and instructors to promote positive attitude changes in online peer assessment activities.     

Accuracy in direct behavior rating is minimally impacted by completion latency

Direct behavior ratings (DBRs) have been proposed as an efficient method to assess student behavior in the classroom due to their relative ease of administration compared to alternative methods like systematic direct observation. DBRs are considered low‐inference assessments of behavior because they are designed to be completed immediately following a specified observation period of student behavior; however, in practice it is common for teachers and other respondents to delay completion of a DBR until they are reminded to do so. It is unclear what effect, if any, this latency between observation and DBR completion has on rater accuracy. Thus, the purpose of this study was to examine the effect of completion latency on accuracy in an analogue setting. Two‐hundred forty‐one undergraduate students (83.8% female) with a mean age of 21 participated across eight groups and were asked to complete an electronic DBR immediately after watching a video of student behavior or after a predetermined delay of 5 minutes, 15 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, or 6 hours. A one‐way analysis of variance revealed that there was no statistically significant relationship between completion latency and DBR accuracy, F(7, 233) = .959, p = .46, η² = .028.     

Examining youth perceptions and social contexts of litter to improve marine debris environmental education

Abstract

Youth have astute observations about site-specific personal and environmental factors that contribute to littering and marine debris, and they have a strong potential to act as change agents in communities. Interactions with youth in Pinellas County Florida add insights into a growing body of research on environmental education and marine debris prevention. This study assessed perceptions of marine debris and littering behaviors through group discussions with middle school and high school students (N = ～44), evaluations at summer camp programs (N = ～31) and pre- and post-assessments of environmental field trips (pre-assessment N = ～120; post-assessment N = ～140). Youth showed high initial awareness of the effects of marine debris on the environment but showed less understanding about the role of watersheds and biodegradation in marine litter issues. A majority of youth attributed others’ littering behavior to dispositional factors, like laziness, while attributing their own littering to situational factors, like poorly placed bins. Student observations of educators and parents also influenced littering behaviors and willingness to act. To reduce littering, education and outreach programs need to (1) provide opportunities for ongoing assessment of complex marine debris topics, (2) align visual and written or verbal messages, (3) reduce actor/observer bias related to littering behaviors, and (4) support adult role models.     

Functional Analysis and Intervention for Disruptive Behaviors of a Kindergarten Student

Abstract

A functional analysis involving interviews and direct observation was used to analyze the multiple disruptive behaviors of a kindergarten student. Following this analysis, an intervention that combined reinforcement and teacher-cued self-monitoring procedures was implemented using an A-B-A-B withdrawal design. The procedures produced a significant decrease in his disruptive behavior and changes in the functions of disruptions across experimental phases.
