Ant communities in the grasslands of the Australian Capital Territory and the role of ants in the ecology of the pink-tailed legless lizard, Aprasia parapulchellaRobinson, Wayne, n/a January 1996 (has links)
This study examined the ant communities of several grasslands of the Australian
Capital Territory (ACT) and their relevance to the pink-tailed legless lizard, Aprasia
parapulchella (Pygopodidae). A. parapulchella is a fossorial species that shares
burrows with, and eats the brood of, several grassland ant species.
Foraging ants were collected from sites by pitfall trapping throughout one calendar
year and comparisons of ant communities made between seasons and sites of differing
vegetation structure. Competition between ant species for artificial nest sites and the
effects of temperature on selection of nest site selection were also studied. The role that
ants play in the distribution of A. parapulchella was investigated by (i) comparing ant
faunas from several sites throughout the geographic range of the lizard, including sites
in New South Wales and Victoria, (ii) performing feeding preference experiments with
A. parapulchella, and (iii) investigating the seasonal nature of brood production and
nest establishment by ants in ACT grasslands. Major findings were used to make
recommendations to assist in the management, including rehabilitation, of
A. parapulchella grassland sites.
Low insolation appears to significantly affect the ant species composition of
grassland sites in the ACT relative to other Australian vegetation types. In the ACT
grassland sites, large species of the Dominant Dolichoderinae functional group were
absent, or present only in very low numbers. The communities were species-poor
relative to other Australian studies with only 60 species being recorded across all sites
studied, with no more than 21 species recorded at any site on any sampling occasion.
Whilst ant species community structure was highly variable between seasons and sites,
more than 95% of ants were from the three functional groups, Dominant
Dolichoderinae, Generalized Myrmicinae and Opportunists. The communities were
numerically dominated throughout the year by the ubiquitous species groups
Iridomyrmex 'rufoniger' and Rhytidoponera 'metallica'. Almost all taxa increased in
foraging abundance during summer months and Pheidole spp., Monomorium spp.,
Crematogaster sp. Paratrechina sp. and Notoncus ectalomoides were occasionally
locally abundant. There were no significant relationships between ant and vegetation
community structures, but Solenopsis sp. showed an alliance with sites that had a high
abundance of Themeda australis (kangaroo grass), whilst Crematogaster sp. and
Paratrechina sp. are potential bioindicators of disturbance from grazing or pasture
improvement.
Iridomyrmex 'rufoniger' were the numerically dominant foraging ants, making up
50% of all captures, but they held only 80% of their nest sites when faced with
competition from other species. R. 'metallica' and Pheidole spp. on the other hand,
gained 80% more nests than they lost to other taxa. I. 'rufoniger' and R. 'metallica'
both preferred nest sites with warmer temperature regimes when given the choice, and
this assisted them to tend brood throughout the year. All ant species in ACT grasslands
had summer peaks in brood production. Most nests were inactive throughout the cooler
months and nest founding was predominantly between September and November. The
common species, Iridomyrmex spp., Paratrechina sp. and R. 'metallica' held winged
reproductives in their nests from April and all ant taxa had released all alates by mid-
November.
Although there were differences in ant community structure throughout the range of
A. parapulchella, the ubiquitous R. 'metallica' and I. 'rufoniger' were always abundant,
whilst again, Dominant Dolichoderinae and associated subordinate taxa were absent or
present only in relatively low numbers. The lizards consumed brood from all the
common ant species in ACT grasslands and showed preference for consuming brood of,
and living with, small Iridomyrmex spp. The range of the small Iridomyrmex spp.
preferred by A. parapulchella extends far beyond that of the lizard. Its distribution is
apparently not restricted by the range of its ant prey species.
For rehabilitation of A. parapulchella sites in the ACT, it is recommended that a
significant ground cover of native grasses is established to ensure the low abundance of
large and territorial ants from the Dominant Dolichoderinae functional group. Along
with a high abundance of shallow surface rocks, this will ensure the establishment of ant
communities that are numerically dominated by small Iridomyrmex spp., which are
preferred by A. parapulchella for homesite sharing and as a food source.

"The extension group" - a part-time, withdrawal, enrichment program for gifted and talented children at Holt Primary School, A.C.T. : an action research studyRoss, Ruth O., n/a January 1985 (has links)
Over the past six years, a part-time withdrawal-from-mainstream-class enrichment program for gifted and talented
children has been operating at the Holt Primary School in the
Australian Capital Territory.
In keeping with the neighbourhood school policy of the ACT
Schools Authority, the program caters only for children within
the school and has included those from grades three to six.
Based on Renzulli's Enrichment Triad Model, the program has
a thematic approach which provides opportunities for participants
to pursue both group and individual research on topics of
interest to them.
Identified children remain in the program for as long as
possible and some have continued for as long as three years when
resources have been available.
This Action Research Study by the Co-ordinator of the
program describes the setting up, objectives, identification
methods, resources and evaluation.

Keyboard laboratories : their adoption and use in A.C.T. educational institutionsRussell, Kathryn, n/a January 1983 (has links)
Since 1977 ten innovatory keyboard laboratories, which enable
teachers to utilize group teaching methods in musical instrument instruction,
have been set up in A.C.T. educational institutions. Reactions to
this innovation have been varied, and its usefulness queried. However,
there has been a lack of information and little evidence of systematic
research in Australia on this topic, perhaps because there are very few
areas outside the A.C.T. where keyboard laboratories are used in schools.
The investigation reported here attempted to determine why the
innovation spread so rapidly in the A.C.T., the uses to which it was
being put, and the kinds of support mechanisms that were necessary to
ensure its optimum use. An interview known as the Levels of Use Interview
was selected as the main method of collecting data from teachers using
keyboard laboratories, and by analysing these interviews in the context of
the A.C.T. educational milieu it was possible to predict a future pattern
of usage, and recommend appropriate action to be taken by administrators
responsible for the organization of A.C.T. education.
The findings of the study supported theories that innovations are
adopted by members of social networks and that the size of the system and
degree of administrative and financial support may positively affect the
spread of an innovation. All teachers using keyboard laboratories were
convinced of their value, although this perception varied according to
factors such as promotional status and recency of teacher training. In
addition, the LoU Interview was found to be a highly appropriate tool for
a practising classroom teacher to use in an investigation of this kind.

Primary-secondary transition : coping in a new school environmentSen, Veronica, n/a January 1978 (has links)
The aim of the Field Study described in this Report
was to examine the nature of primary-secondary transition
as perceived by students themselves. Twelve students from
four A.C.T. primary schools were interviewed prior to their
entry to one or other of two high schools, and subsequent
interviews were conducted at intervals during the students'
first six months in high school. Further information was
obtained from interviews with their parents and from formal
and informal assessments made by their primary and
secondary teachers. To place the trends revealed in the
interviews in a wider context, surveys were administered
at the beginning and end of the six months' period to all
Year 7 students in both high schools.
A major emphasis of the Study was an investigation of
how students cope with new tasks, social and academic, at
a time when there is a potentially stressful conjunction
of early adolescence and major educational transition.
Such coping is conceptualised as the individual matching
his resources against the demands made by a new situation.
The initial appraisal by students of the new situation
was a general perception of high school as either benign or
threatening. The more differentiated, or secondary,
appraisal was influenced by further information and
experiences; and re-appraisal was characterised, after a
further lapse of time, by either a reinforcement or reversal
of original perceptions.
It was found that upon moving to the more complex
institutional setting of high school some students had
difficulty in adjusting to a more formal organisation and
a more demanding curriculum. The students' response to
high school included such coping strategies as hostility,
withdrawal or active striving to meet the challenge of a
new school. Some students who showed a marked inability
to cope with one or more of the tasks, social or
academic, of high school were deemed to have experienced
adaptive failure.
A key factor in adjustment to high school, and one
that was at least as important as academic achievement,
was that of interpersonal relationships. Success in
relating to both teachers and peers was found to be a
crucial factor for students, whether bright or less
bright, and it was found that students of limited academic
achievement could find compensation if they perceived
their "person environment" as benign.

Peer counselling in schools : an experimental study of human relations training in an A.C.T. high schoolSimic, Ann, n/a January 1982 (has links)
The main purpose of this study was to examine the efficacy of
a human relations programme for high school students in Years 7, 8
and 9. The programme, based on the course devised by Varenhorst (1976;
Appendix B), was run as a non-assessable option for one semester in an
A.C.T. high school by the author, who was the counsellor at the school,
and a volunteer teacher. Humanistic, behavioural and cognitive methods
of implementation were used.
As well as trying to achieve more effective interpersonal relations
between students, so that they could more successfully relate and resolve
differences, a secondary aim was to try to make the counsellor's role
a more preventative rather than a largely remedial and crisis-laden one.
Twenty-eight students enrolled for the course. Fourteen were
assigned to the experimental group and experienced the human relations
programme; the fourteen in the control group undertook a variety of
other options they had chosen. Both groups completed pre- and postquestionnaires
from which quantitative data was gathered. As a check
on these quantitative results, post-study qualitative data were also
gathered from the experimental group.
The course taught verbal and non-verbal communication skills,
decision-making and problem-solving skills, particularly in relation to
such areas as the peer group, the family and the school. The ethics
of helping others experiencing problems in any of these areas was an
integral part of the course.
iv
The study showed that human relations skills can be taught,
although the findings were interpreted cautiously because of design
and methodological difficulties. The lack of randomisation and
reported, rather than behavioural, change per se are two areas which
restrict the generalisability of the results.
It is suggested that, to achieve more widespread gains, such a
course could be incorporated into the existing pastoral care programme
of the school in which all teachers and students took part. It is
further suggested that, for optimal effectiveness, parents and teachers,
as well as students, would need to be aware of, and know how to put into
practice, the skills taught in this programme and relate them to interaction
generally.
A first step was made by the experimenter towards widening the role
of the school counsellor away from crisis cases towards prevention of
problems. Ideally, the programme could be expanded to include teachers
and parents who could, in turn, become human relations educators, thus
serving the whole student population.
The teaching, learning and practising of skill became the main focus
of the programme. Although some peer counselling was involved in assignments,
time precluded an experimental study of effectiveness in this
applied area. All students but one wanted to proceed with this practical
work.

Influences on teachers' discipline in the primary schoolSloane, Alwyn M., n/a January 1987 (has links)
The study described in this report attempted to investigate the area of classroom discipline in the primary
school. In particular the objectives were to ascertain the
factors which influences teachers' knowledge of discipline
procedures and the factors which influence teachers'
implementation of discipline procedures.
The study first examined discipline policies and
practices in Australian schools generally and in Australian
Capital Territory government schools in particular. A review
of the literature indicated that the area of discipline in
the classroom is one which seems to be increasingly
important in the range of presage variables under
investigation by researchers.
Information was obtained from sixty completed
questionnaires from primary teachers in eight primary
schools. Respondents indicated that they taught over the
full range of primary school years/grades. Results suggested
that senior management in the schools appeared to have a
relatively unimportant role in influencing classroom
teachers' discipline programmes.
The results indicated that the in-school influences
which were perceived as the most influential on both
teachers' knowledge of discipline procedures and on
teachers' current discipline procedures were a) those
connected with pupils and b) factors about the personal
preference of teachers.
The out-of-school influences which were perceived as
the most influential on both teachers' knowledge of
discipline and on teachers' current discipline procedures
were a) those connected with professional development and b)
factors about the intuitions and reactions of teachers.
Results in general suggested that some primary
teachers may be depending or) outdated information regarding
school and classroom discipline programmes. These findings
could have important ramifications for teacher training
agencies regarding the allocation of resources to the area
of school discipline programmes.

Change, conflict and control : a case-study on the incorporation of the Neighbourhood Community Centre into the ACT government school system and its first year of operation as the Co-operative Peoples SchoolSmith, Libby, n/a January 1982 (has links)
This field study is an examination, by a partisan participant
observer, of the Neighbourhood Community Centre and its first year
of operation as the Co-operative Peoples School, in the ACT government
school system.
The Neighbourhood Community Centre was a small, alternative,
independent school for children from three to eight years of age. The
school's philosophy was progressive and its management policies and
structures co-operative and non-hierarchical. For two years, parents
campaigned to become part of the ACT government school system. In
February 1978, the school opened as a government school, with funding
and staffing arrangements similar to other schools in the ACT.
Soon after incorporation, the distinctive attributes of the
Neighbourhood Community Centre began to disappear. Conflict became
the dominant characteristic of the new school: the degree, extent
and duration were extreme for a group that had asserted a commitment
to consensus and co-operation. Two identifiable and, ultimately,
irreconciliable parent factions emerged.
Three factors were linked in the events of 1978: conflict,
ideology and power struggles in a situation of change. These factors
do not easily fit into the dominant sociological paradigm, functionalism,
as an explanation of the events of 1978, for the concept of power has
been, at best, slow to be incorporated into that sociological tradition.
Yet the events, to this observer, were linked to a political struggle
between competing groups for the domination of the school: power was
a major dimension. Only at a superficial level was the conflict
ideological.
Parent factions concealed a third group, the teachers, who
were striving to dominate the school, a domination that was not
accepted unequivocally in the new school. Their ultimate success
depended not on their coalition with a parent faction, the support
of the Schools Office, strategies for isolating criticism and critics
and their professional ideology; their success depended on their
structural power within the school system which provided resources,
support and justification for their position.
This analysis endorses sociological theorists who maintain that
power, and structural power in particular, is a central concern in
organisational life. The failure of the Co-operative Peoples School
was linked to the unequal distribution of power within the co-operative.

Transition from high school to college in the A.C.T.Strauch, Helen M., n/a January 1979 (has links)
This study examines some aspects of the transition of students
from high schools to a particular college in the A.C.T.
The stimulus for the study arose from the writer's perception
of problems being experienced by beginning college students and a
concern that these were in part due to the recent restructuring of
secondary education in the A.C.T.
The study investigated a number of areas affecting the
transition experiences of students moving from high schools to
Hawker College. A comparative study was undertaken of the various
curricula of the feeder high schools and of the College. Instruments
were devised to measure student's perceptions of their transition
experiences and of their orientation to the College. Interviews
were conducted with College and high school teachers, a random
selection of parents and some ex-students. The modified American
CUES questionnaire used by Whitta in Queensland formed the basis of
a study of environmental press in the high schools and College. An
analysis was also undertaken of the nature and extent of communication
between the high schools and College.
Results indicated that for most students the transition to the
College was short and relatively smooth, although not without
problems. However 10 to 15 per cent of students, particularly
those of lower ability and low motivation, were observed to have
experienced a difficult and often prolonged transition. Problems
for students arose from a sudden increase in the amount of freedom
given them, a significant rise in teachers' expectations of their
written language skills and their lack of self-organisational skills.
On the basis of the findings certain recommendations are made
aimed at increasing the communication between teachers in high
schools and the College and at improving the orientation of students
to the College. Other recommendations are concerned with easing the
transition of students, particularly those most likely to experience
transition problems.

Simultaneous and successive synthesis and their interaction with instructional treatments in year eigth mathematics in the A.C.T.Sullivan, Carolyn Wendy, n/a January 1987 (has links)
This study addresses the criticism leveled at A.C.T.
Mathematics teachers with regard to their failure to use
any other method of teaching than chalk-and-talk. By
considering the changed needs of society for mathematics
and the changed perceptions by society of education, the
criticism is placed in context.
The importance of spatial ability for mathematics is
examined in the context of theories of cognitive abilities
and its current under utilization within the classroom. On
the basis of the increased need to utilize more talent the
study was designed to operationalise in the classroom the
constructs of simultaneous and successive synthesis,
derived from Luria's model of brain functioning.
The question of gender differences in mathematics
achievment and spatial ability is addressed.
The possible role of the maturation of language in
determining differences in the acquistion of ability to
form simultaneous synthesis is briefly discussed.
The study was designed to utilize and enhance
simultaneous synthesis. By demonstrating an
Aptitude-Treatment Interaction it was intended to confirm
that students, who function at a high level in
simultaneous synthesis but at a low level in successive
synthesis, would achieve more with experience with spatial
activates than in a more traditional chalk-and-talk
classroom.
Gender differences in achievement were not found.
Gender differences in successive/simultaneous profiles
were found in accordance with theory predictions. The need
for the duration of longer treatment periods is briefly
discussed in the context of funding and the appearance of
greater efficiency of traditional teaching methods when
the students are functioning at the highest level of
symbolic thought.
