A constructivist framework for online collaborative learning:adult learning and collaborative learning theory

The purpose of this chapter is to review and discuss theoretical perspectives that help to frame collaborative learning online. The chapter investigates literature about the type of learning and behavior that are anticipated and researched among participants learning collaboratively and discusses how these attributes explain computer-supported collaborative learning. The literature about learning is influenced by perspectives from a number of fields, particularly philosophy, psychology, and sociology. This chapter describes some of these perspectives from the fields of cognitive psychology, adult learning, and collaborative group learning. Recent research into computer-supported collaborative learning that applies these theories will also be discussed.

Adult rape scripting within a victimological perspective

This review of the adult rape experience draws from theoretical conceptualizations in both psychology and victimology. It is an integrative discussion of Lerner's [Lerner, M.J. (1980). The Belief In A Just World. New York: Plenum] victimological theory of the “just world” and Gagnon and Simon's [Gagnon, J.H., & Simon, W. (1973). Sexual Conduct: The Sources of Human Sexuality. Chicago: Aldine] conceptualization of cognitive sex scripting. The “just world” is one in which an individual gets what he/she deserves. People will construe events and interpret the character of people to maintain this ideology. As theorized by Perloff [Perloff, L.S. (1983). Perceptions of vulnerability to victimisation. J Soc Issues 39, 41–61], this promotes a feeling of “unique invulnerability” in the absence of victimization. However, should victimization, such as rape, occur, this ideology can implicate detrimental effects of adjustment. This includes the “secondary victimization” from others, as theorized by Williams [Williams, J.E. (1984). Secondary victimisation: confronting public attitudes about rape. Victimol Int J 9, 66–81]. These victimological perspectives are cognitive scripts. They develop over time from exposure to family dynamics, sociocultural tenets describing gender roles and sexual conduct, and from an individual's parameters and dimensions of sexual individuality and disposition. How these victimological scripts may impact on the adjustment of adult raped men and women is discussed.

Multiple forms of child abuse and neglect: adult retrospective reports

There are few research reports of the experience of multiple forms of child abuse and neglect (multi-type maltreatment). A critical review is presented of 29 studies in which adult retrospective reports of more than one form of child maltreatment (sexual abuse, physical abuse, psychological maltreatment, neglect, or witnessing family violence) are assessed. Empirical investigations of the extent and impact of multi-type maltreatment are identified. Data on the relationship between the different forms of maltreatment and the adjustment problems associated with each type of maltreatment are critiqued. As well as using dichotomous measures of maltreatment, an important methodological problem was the failure of researchers to assess all child maltreatment types, the relationship between multi-type maltreatment and adjustment, and the role of variables influencing the occurrence or impact of maltreatment. Considerable overlap was found in the occurrence of maltreatment types. The compounding or interacting effects of experiencing multi-type maltreatment were ignored in many studies. Where an assessment was made of the specific impact of multi-type maltreatment, it was associated with greater impairment than single forms of abuse or neglect. A multi-dimensional approach to prevention and treatment of child abuse and neglect is required in which children's vulnerability to multi-type maltreatment is addressed.

Foods prepared outside the home: association with selected nutrients and body mass index in adult Australians

Objective: To determine the proportion of energy from foods prepared outside the home (FPOH) and the relationships with energy and nutrient intakes and body mass index (BMI).

Design: A nutrition survey of a representative sample of the Australian population aged 18 years and over (n = 10 863). Measure used was a 24-hour dietary recall. Underreporters (energy intake/estimated basal metabolic rate (EI/BMR) <0.9) were excluded from analysis. Daily energy and selected nutrient intakes were calculated using a 1996 nutrient composition database for all foods/beverages during the 24-hour period.

Results: On average FPOH contributed a significant 13% to total energy intake. About a third of the sample had consumed FPOH in the last 24 hours and on average this group consumed a third of their total energy as FPOH. The relative contributions of fat (for men and women) and alcohol (for women) were significantly higher for those in the top tertile of FPOH consumers. The intakes of fibre and selected micronutrients (calcium, iron, zinc, folate and vitamin C) were significantly lower in this group. After adjustment for age and income no relationship between FPOH and BMI was observed.

Conclusions: FPOH make a significant contribution to the energy intake of a third of the Australian population. FPOH contribute to poor nutritional intakes. Altering the supply of FPOH may be an effective means of improving diets at a population level.

The transition from pediatric to adult health care services for young adults with a disability : an ethical perspective

Young children with disabilities and their carers or parents tend to form a long-term dependent relationship with a paediatrician throughout childhood At some stage when the young person with a disability reaches early adulthood, the relationship is severed This paper draws upon recent research undertaken by the authors that describes the difficulties experienced by young people with disabilities as they go through the transition from paediatric care to adult mainstream health care services. The purpose of this article is to present the argument that the dependent, paternalistic relationship that tends to exist between young people with disabilities (and/or their carers) and paediatricians throughout childhood does not facilitate the successful negotiation of adult mainstream health care services, nor optimally promote the well-being of these young people with disabilities. It is proposed that the promotion of autonomy (or self-determination) via a well planned transition program will increase the likelihood that young adults with disabilities and/or their carers will be empowered to successfully negotiate the current mainstream health care system in Australia, and will enhance the well-being of young adults with disabilities.

Child maltreatment, family characteristics and adult adjustment: mediating and moderating processes

Two alternate processes that may explain the relationship between child maltreatment, childhood family characteristics and adult adjustment (mediation and moderation) were tested using retrospective data from a community sample (N = 175). The levels of five different types of child maltreatment did not mediate the relationship between childhood family variables and adult adjustment. In contrast, family background played a mediating role in the relationship between maltreatment and adjustment. Evidence of moderation was found in the interactions between different maltreatment types in predicting adjustment. Partial support was found for the moderating influence of family factors on the relationship of maltreatment to adjustment.

Breeding biology, adult survival and territoriality of the white-browed treecreeper (climacteris affinis) in north-west Victoria, Australia

This is the first study to present empirical data describing the social organisation and breeding biology of the White-browed Treecreeper (Climacteris affinis). The species is typical of many small Australian passerines in that it has high annual survival (~80%), small clutches (mean = 1.95 ± 0.05), long breeding seasons (eggs laid August to November) and long incubation (17–18 days) and nestling periods (25–26 days), corrected for body weight. Reproductive effort is modified in response to variation in climatic conditions by adjusting the commencement of breeding and number of clutches laid per season, which is facilitated by an extended breeding season. White-browed Treecreepers occupied relatively large (mean = 8.4 ± 0.8 ha), all-purpose territories throughout the year. However, unlike many group territorial birds, territory size was not related to the number of occupants. The role of food limitation and climatic variability in relation to territory dispersion and life-history traits is explored. Facultative cooperative breeding was confirmed. Cooperative groups were formed through male philopatry, with usually only one, but up to three, male helpers present in a moderate fraction (35%) of breeding units. Thus, all species of Climacteris are now confirmed as facultative cooperatively breeding species, which provides further evidence for the aggregation of cooperative breeders at the generic level in mixed (i.e. cooperative and pair breeders) phylogenetic clades. In C. affinis, males may attain breeding positions through inheritance of their natal territory or by filling vacancies in nearby territories. Females obtained breeding positions by ‘floating’ as non-breeding residents in established territories, waiting for a vacancy to arise.

Adult learners in the workplace: online learning and communities of practice

Seven in-employment postgraduate Master's level students in an e-learning unit participated in this research, designed to identify tensions between participation in a community of learning that was part of their studies, and participation in the communities of practice that they were engaged in at their workplaces. It was hypothesised that participation in both these forms of community in their different contexts may enhance each other, or could potentially have a disrupting effect on each. The research employed an interviewing technique. The students' perceptions of the impact of participation in the one form of community on their participation in the other was mixed, with some suggesting that it was enhancing, and others suggesting the contrary, or that there was no impact. The findings indicate that the enhancing effect of participation in communities of learning relevant to a learner's workplace community of practice occur when the learning tasks are designed to enable negotiation of tasks and collaboration with learners who have similar workplace issues.

Training for the new work order : the adult classroom as a site of class(ed) work

This paper reports on a qualitative case study that investigated how the professional identities of trainers in the adult sector in Australia are shaped by intersecting relations of social class, ethnicity, gender and the discourses of vocational adult education. Interviews with two trainers as well as observations of them at work are analysed and presented here to illustrate how social class, considered in relation to gender and race, is played out through the trainers' identity investments in discourses of nurturance and care and economic rationalism. Such identity investments shape the relationships the trainers develop with their students and the training strategies and practices they privilege. The paper argues the need for trainers to develop critical reflective practices and to interrogate how their investments in particular classed identities shape their views about learning for work and training for work. It also argues the need for more research around social class and trainer identity within the adult sector.

The effect of focus on form in the written work of adult learners of Arabic

One of the key debates within SLA research circles concerns grammar
- whether and hov to include it in second language (L2) instruction. 'Noninterventionist' approaches to language leaching, which centre on focus on meaning (FonM) , have been found to be neither economical nor expedient in terms of use of learners' classtime (Long & Robinson, 1998). This paper is a study of the effects oj direct grammatical instruction within a communicative context (Focus on Form - FonF) on the accuracy rate of the use of noun-adjective agreement in the written work of adult learners of Arabic. Learning the systems oj noun/adjective agreement in Arabic presents problems for beginners since. unlike languages such as English. Arabic needs to be modified for gender, number. definiteness and case. Through teaching material and methods, first-year university English speaking students of Arabic were directly exposed to morpho-syntactic inflections relevant to noun-adjective agreement. In post-tests over an extended period. instructed students showed a higher accuracy rate of some forms than their uninstructed colleagues. suggesting focusing on form is beneficial to the Arabic learner and does not need to interrupt the communicative flow in the classroom (Ellis et al. 2001).

Australian adult consumers' beliefs about plant foods: a qualitative study

This exploratory qualitative study examined consumers’ perceived barriers and benefits of plant food (fruits, vegetables, grains, legumes, nuts, seeds) consumption and views on the promotion of these foods. Ten focus groups were conducted in Melbourne, Australia. Groups consisted of employees of various workplaces, community group members, university students, and inner-city residents. Health-related benefits predominated, particularly relating to the properties of plant foods (e.g., vitamins). Taste, variety, versatility, and environmental benefits were also considered important. The main barriers to eating plant foods were lack of knowledge and skills and length of preparation time. The poor quality of plant foods was also an issue for consumers. Awareness of the promotion of plant foods was generally high. Participants noted that promotions require a stronger practical emphasis with a focus on quick, easy-to-prepare foods and meals. These findings provide insight into effective ways to promote a higher consumption of plant foods

The dynamics of adult education : effectiveness of financial education seminars

This study examines the impact of adult education seminars in superannuation investments for retirement has on the investment intentions and decision making of those adults attending the seminars.  The socio-political context of the data is that of an aging population and a future government being unable to afford the current level of age pensions being paid, and attempting to encourage individuals to plan and provide for their own financial well-being in retirement.  Three themes emerged from the data and were seen to be representative of the major issues found in adult education for financial self-sufficiency: education for knowledge, education for decision making, and education for action.  In an attempt to measure the immediate impact of the seminar on the attendees decision making, the investment intentions of seminar attendees were captured at the start and end of the seminar. This was followed up three months later to see whether the intentions expressed at the end of the seminar had been implemented.  The immediate impact of the seminar was to encourage the respondents to express an intention to increase their investment strategy, however when the follow-up was done three months later, the results were mixed. Some respondents who did not express an intention to change their investment strategy actually made changes, and other respondents who did express an intention to make a change, did not do so.

Assessing adult adjustment to relationship separation : the Psychological Adjustment to Separation Test (PAST)

Relationship separation is associated with substantial adult adjustment problems. The Psychological Adjustment to Separation Test (PAST) was developed as a self-report measure of 3 key dimensions of separation adjustment problems: lonely negativity, ex-partner attachment and coparenting conflict. Two independent samples (n = 219 and n = 169, respectively) of recently separated adults, 60% of whom had children, completed the PAST and other measures of general adjustment. Exploratory and confirmatory factor analyses demonstrated a replicable 3-factor structure, with each factor showing satisfactory test–retest and internal reliability and good convergent and discriminant validity. The PAST meets initial criteria for a potentially useful new measure of adult separation adjustment.
