The diploma thesis deals with a didactic use of selected angiosperms in teaching at elementary and high schools. It provides theoretical knowledge concerning angiosperms, selected families, and plant species. Furthermore, it describes selected teaching techniques and methodology which can be used in teaching of the angiosperms. This thesis contains specific suggestions of the teaching methodology dependent on the selected plant families. A part of the thesis is a questionnaire survey, which contains the use of various forms and methods of teaching in natural science lessons at elementary schools and high schools. The results of the practical work are represented by practical exercises, worksheets and didactic games which teachers could use in teaching of the angiosperms. Key words: teaching techniques and methodology, questionnaire suvey, angiosperms

The lifetime prevalence of clinical depression in patients living with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) is approximately 22% compared to 3% to 10% in the primary care population. The nursing practice problem at the project site concerned nurses' lack of knowledge and understanding of procedures to help ensure that all patients living with HIV/AIDS were properly screened for depression and referred for further evaluation and treatment. The purpose of this project was to implement a staff education module to address the use of the PHQ-9 screening tool to identify depression in people diagnosed with HIV/AIDS. The theoretical framework for this educational module was the theory of planned behavior. The practice-focused question explored the extent to which the implementation of an evidence-based practice education model in a primary care clinic treating patients living with HIV/AIDs would increase staff knowledge on the use of the PHQ-9 tool to screen for depression. A staff education project incorporating a pretest and posttest design was conducted to determine whether a significant change existed in the test scores of the participants between the pretest and the posttest. After completion, the posttest measures showed an improvement of 35%. The implications of this project for social change might include improvement in the knowledge, attitudes, and practices of the nurses in the treatment of depression in adults living with HIV/AIDS.

Eating disorders are alarmingly prevalent and potentially lethal. The proper assessment of eating disorder symptoms is therefore crucial for the early identification and treatment of those suffering from these serious illnesses. Current measures of eating disorder symptoms are either very narrow in scope (e.g., assess only one aspect of disordered eating, such as bingeing) and/or have one or more serious limitations, such as inconsistent factor structures and/or poor discriminant validity. Because several of the existing measures of eating disorders were created over 20 years ago, many of these limitations are the direct result of out-dated scale development methods and testing.The goal this study was to determine the structure underlying the symptoms of eating disorders and develop a multidimensional measure of eating pathology based on this structure. To accomplish this goal, an initial item pool was developed to assess 20 dimensions of eating pathology. The initial item pool of 160 items was administered to a student sample (N=433) and community sample(N=407) to determine the preliminary structure of the measure using exploratory and confirmatory factor analyses. The revised measure was then administered to independent samples of psychiatric patients (N=190) and students (N=227). Exploratory and confirmatory factor analyses revealed a 7-factor structure that showed excellent convergent and discriminant validity. The final measure was also internally consistent (median coefficient alphas ranged from .84-.89) and reliable over a two- to four-week period (r's ranged from .70-.84). The current study represents one of, perhaps, the most comprehensive scale development project ever conducted in the field of eating disorders and is expected to improve future basic and treatment research focused on eating disorders.

This correlational study attempted to determine if the Outcome Questionnaire can be used to collect the same information as the Revised Dyadic Adjustment scale in marital assessment. Both measures are common pretreatment assessments and have relational components. The study used secondary data from the Utah State University Marriage and Family Therapy Clinic. Reliability and correlational tests were performed and the results indicate that the assessments measure different constructs. There also were no statistically significant correlations when comparing the measures by gender, marital distress, and marital satisfaction. Implications are discussed including the formulation of new clinical cut-off scores and the importance of using both measures to perform better assessments.

The researcher examined the relationships between tuberous sclerosis, a multi-system genetic disorder, and school functioning through the use of a parent questionnaire and behavior rating scale. Information was gathered on the typical school experiences of children with tuberous sclerosis, including educational placement and services, behavioral functioning, parent involvement, and parent satisfaction. The results indicated that the majority of students with tuberous sclerosis are in special education and receiving related services. Three-quarters received one or more related services through the public school, and 30% received private related services paid for by their parents. Parent involvement was positively correlated with parent satisfaction, and negatively correlated with t-scores on the Withdrawn/Depressed subscale of the CBCL. Parents of children receiving Autism services were generally less satisfied with their children's school experiences than other parents. Parent satisfaction was negatively correlated with the Attention Problems scale of the CBCL. Student age was negatively correlated with time in inclusion and with related services. This information forms the basis for a discussion of school psychologists' roles in the educational success of students with tuberous sclerosis and the critical areas towards which interventions should be directed.

The major purposes of this study were to provide validation data for the Questionnaire on Teacher Interaction (QTI) with a large Australian sample and examine the relationship of teacher-student interpersonal behaviour with student sex, cultural background and student outcomes. The sample from lower secondary science classrooms in Australia consisted of 3,215 students in 158 classes in 43 schools in two Australian states, namely Tasmania and Western Australia. The sample was chosen carefully so as to be representative, though only co-educational classes were used in order to permit an unconfounded test of sex differences. Students and teachers completed a questionnaire which included the QT1, an attitude to class scale based on the Test of Science Related Attitudes (TOSRA), a cognitive achievement measure based on items from the Test of Enquiry Skills (TOES) and a five-item cultural background survey. The study follows the current trend in the field of classroom environment research of combining qualitative and quantitative methods. The qualitative component of the study involved about 100 interviews. This study is unique in that it provides a very large database of teacher-student interaction data in science classrooms and provides new insights into the relationships between teacher-student interpersonal behaviour with student sex, cultural background and student outcomes. The study found that there were associations between teacher student interpersonal behaviour and student sex and that there were differences in the way that students from different cultural backgrounds perceived their learning environments. Student achievement and student attitude to class were also found to be positively associated with teacher-student interpersonal behaviour. As a practical outcome of this study, the 48-item QT1 has been shown to be useful to Australian lower secondary science ++ / teachers as an initiator of self reflection on teaching practice.

The first purpose of the study described in this thesis was to provide validation information of three questionnaires that were modified and translated into the Thai language, namely, the Questionnaire on Teacher Interaction (QTI), the Science Laboratory Environment Inventory (SLEI), and the Attitude to Biology Class (ABC). A second purpose was to determine students' perceptions of teacher-student interactions and laboratory learning environments and their attitudes to biology classes in secondary schools in Thailand. A sample of 1,194 students from 37 biology classes in 37 schools completed the three questionnaires. The results of the study showed that most students in secondary schools of Thailand have moderately positive attitudes to their biology class. Students perceived their teachers as having good leadership, being helping/friendly, and understanding, but seldom uncertain, dissatisfied or admonishing. They also perceived that sometimes their teachers were strict, however allowing students responsibility and freedom. In biology laboratories, they perceived the environments as employing good student cohesiveness, less open-endedness and integration of the theory and practical, the rules were not clear and the materials were not good and insufficient. There were differences between students' actual and ideal perceptions of classroom interactions and laboratory learning environments. Students preferred teachers who showed strong leadership, were more helping and understanding, who gave their students more responsibility and freedom, and who were less uncertain, dissatisfied, admonishing and strict. / Also, students preferred a biology laboratory environment with higher levels on the scales of Open-Endedness, Integration, Rule Clarity, and Material Environment but not Student Cohesiveness. Some commonality between the QTI and the SLEI scales was found in their contributions to the variance in student attitudes to biology classes. So now the QTI and the SLEI can be used by biology teachers and other science teachers in secondary schools who wish to improve science teaching and learning in Thailand.

This longitudinal study explored the extent to which mathematics education lecturers' constructivist beliefs and aligned practices were communicated to students in a New Zealand primary pre-service teacher education degree programme. An integral part of this exploration was the identification of particular aspects of lecturers' practice that had a significant impact in enhancing the adoption of constructivist ideas on learning and constructivist-aligned teaching practices by student teachers. This goal had a practical focus on more effective course teaching within the chosen philosophical framework of constructivism. At a more theoretical level, there was a focus on the development of a constructivist approach to teacher education for teacher educators through the medium of mathematics education. A potential outcome of the development and widespread adoption of such a constructivist-aligned pedagogy within teacher education could be the significant furthering of a "reform" (or transformative) agenda in school education with its potential for enhanced learning by children. The methodology comprised both quantitative (survey) and qualitative (interview) techniques to collect information which allowed the capture of different but complementary data, so building a "rich" data set. The surveys were conducted using two leaming environment instruments underpinned by particular constructivist perspectives: one focusing on the overall nature of the learning environment at an individual level from a critical constructivist perspective, and the other focusing on the nature of interactions between teacher and student teachers at a classroom level from a socio-cultural constructivist perspective. / Surveys were conducted with the lecturers at the beginning and toward the end of the study, while the student teachers in these lecturers' classes were surveyed over a three year period. The interviews were semi-structured following an interpretative (evolving) research approach, with the "results" of ongoing data analysis being fed into later interviews. The interview data were analysed for personal perceptions and understandings rather than for generalisation and prediction with the intention of focusing on the identification of emergent themes. Interviews were conducted with lecturers at the beginning of the study and again toward its conclusion while student teachers were interviewed at the end of the study. The lecturers claimed constructivism as their underlying philosophical belief system and the initial surveys established baseline data on the actual nature of the lecturers' beliefs and how these were perceived by the student teachers. Similarly, the initial interviews explored the espoused beliefs and congruent practices of lecturers and student teachers. These two sets of data were compared to establish their congruence or otherwise. Further interviews with the lecturers focused on the survey data and my reconstruction of what the lecturers had said previously when interviewed. Later survey and interview data were also examined against the baseline data for evidence of change over the four years of the study. The data demonstrated that the student teachers perceived the existence of moderate to strong socio-cultural constructivist-aligned classroom environments when considered at a class (group) level, and a moderate alignment with critical perspectives at the individual (personal) level. / There was a high degree of consistency between staff and student teacher views, and the student teachers' views were consistent across the year groups (first, second and third years) and throughout the four years of the study. Lecturer practice(s) congruent with constructivism were the basis for student teacher change toward understanding and their adoption of constructivist ideas and aligned practices. Specific lecturer practices were identified as particularly effective in achieving such change. These effective lecturer practices may assist in establishing the foundations of a constructivist-aligned pedagogy for teacher education. The lecturers' modeling of the practices they were promoting for student teachers' practice was identified as a key element in promoting change. Indeed, the tension between traditional and transfornative approaches was exacerbated in situations where lecturers' promotion of a preferred practice was different from that which they enacted. The continuing existence of such situations and associated tensions has the potential to limit the extent of any change.

The aim of this research programme was to examine the 3P model of learning (Biggs, 1987a, 1999). The first stage necessarily involved an examination of the Study Process Questionnaire (SPQ) (Biggs, 1987a), an instrument developed to measure the process component of the model. The structure of the SPQ was examined utilising exploratory and confirmatory factor analysis of undergraduate responses (n= 260). The results indicated the higher-order factor structure of deep-achieving and surface-achieving-motive provided the most reliability and a better model fit than either the subscales or scales of the SPQ. The construct validity of the two constructs deep and surface was assessed next using a multitrait-multimethod matrix (MTMM) constructed from the three measures of the self-report questionnaire, interview ratings and written assessments from first-year students (n = 50). The results indicated good convergent validity between the deep scale of the SPQ and the interview ratings on the deep scale, between the deep scale on the SPQ and the written assessment ratings, and between the interview ratings and written assessment ratings. The results indicated good convergent validity between the surface scale on the SPQ and the interview ratings on the surface scale, but not between the surface scale on the SPQ and the written assessment ratings, and between the interview ratings and written assessment ratings. The discriminant validity between deep and surface was good for the SPQ, but not for either the interview or the written assessment. The findings indicate the deep and surface scales of the SPQ adequately measure the underlying deep and surface constructs. The retest reliability of the SPQ was then examined utilising Spearman’s Rho to assess the rank-order correlations with a sample of third-year students (n=87). Over a period of three months there were significant correlations for the surface motive, surface strategy, deep strategy, achieving motive and achieving strategy subscales of the SPQ, suggesting good reliability for these subscales. The results at the scale level of the SPQ result in similar conclusions. There was a moderate significant correlation for the surface, deep and achieving scales of the SPQ, suggesting the scales have good reliability over a period of three months. There was also a moderate significant correlation for the surface-achieving-motive and deep-achieving scales over a period of three months. The stability of SPQ scores was also assessed utilising a series of one-way repeated measures MANOVA’s with a sample of third-year undergraduates (n = 64). The results suggest some change occurs in self-reported use of approaches to learning between the first and third-years of an undergraduate degree programme. The role of the teaching-learning environment was next examined. Utilising a within-subjects design, undergraduate students (n=48) concurrently enrolled in traditional (viz. lecture and tutorial) and non-traditional (viz. workshops and group projects) subjects completed the SPQ to describe their approaches to learning in each subject. A series of 2x2 repeated measures MANOVA’s were undertaken. The results indicated students were likely to change their approach to learning based on their perceptions of the learning environment (traditional or non-traditional subject). However, those students identified as predominantly surface learners significantly increased their deep scale scores in the non-traditional subject when compared to deep learners. The next study examined a range of personality (locus of control, sensing function, thinking function, intelligence) and demographic variables (age, gender, year of study) to assess which were good predictors of deep and surface approaches to learning. A series of regression analyses identified age, sensing function and locus of control as significant predictors of the surface, surface-achieving-motive, and deep approaches to learning. Locus of control was found to be a significant predictor of the deep-achieving approach to learning. The final study examined the 3P model of learning. Based on the results of earlier studies in the research programme the situational component of the presage factors was not included. The model was examined using structural equation modelling (n= 394). Two initial models were tested using both the three (deep, surface, achieving) and two (surface-achieving-motive and deep-achieving) process factor models. The three process factor model provided the better model fit. The results suggest deep and surface approaches to learning do not mediate between personal characteristics and learning outcomes (i.e. GPA). The results of this series of studies suggest the need for further research into the SPQ and the 3P model of learning. The implications of the research programme are also discussed.

Sufficient physical activity, a key prerequisite for health, is lacking in many teenagers. Limited knowledge, however, exists about who, when, why, and if New Zealand teenagers are getting their daily dose of health-related physical activity. At conception of this thesis, available information was predominantly survey-derived with no New Zealand data and few international studies that had assessed adolescent physical activity levels objectively. Data were collected from three projects. Convenience sampling was used across all projects to recruit students from low-decile high schools located in the Auckland region. For Project 1, 236 Year 9 to Year 13 students each wore a pedometer for five days (three weekdays and two weekend days) and reported their mode of transportation to and from school. To explore ethnic and sex-specific perceptions of physical activity among youth (i.e., barriers, benefits, potential physical activity enhancing strategies), Project 2 involved nine focus group discussions with 44 Year 9 and Year 10 students who identified as Māori or European. Project 3 was a large cross-sectional study of 3,451 high school students (Years 9 - 13) from seven low-decile schools. Through this project the following self-reported data were collected: demographics, physical activity levels during four school-day physical activity opportunities (i.e., active travel, lunchtime physical activity, recess physical activity, after-school physical activity), sedentary behaviour (i.e., school-day television (TV) watching), level of perceived encouragement to be active, and the presence of home policies regarding TV use. Analyses revealed low physical activity participation and high TV use behaviours. Pedometer data showed that only 14.5% of participants achieved a conservative criterion of 10,000 steps daily. Also, daily steps varied by age group (junior students: 11,079 ± 330; senior students: 9,422 ± 334), sex (males: 10,849 ± 381; females: 9,652 ± 289), time of week (weekday: 12,259 ± 287; weekend day: 8,241 ± 329), and transportation mode to/from school (walkers: 13,308 ± 483; car transit users: 10,986 ± 435). Low school-day physical activity levels emerged, especially during school hours (i.e., during recess and lunchtime). Based on dichotomised grouping (less active versus more active), the proportion of students in the ‘more active’ group during morning recess and lunchtime, after school, and as part of active travel to/from school were 26%, 32.4%, 56.3%, 58.1% respectively. Only 11.1% of participants were in the ‘more active’ group across all four physical activity opportunities. The focus group data revealed primarily social benefits of physical activity (e.g., meeting new people, fun). Barriers were mainly environment-related and included lack of peer support, low accessibility to and availability of physical activity opportunities, alternative sedentary activities, structure of physical education classes (females only), and distance between home and school (in terms of active transportation). Potential strategies to increase physical activity reflected the articulated barriers and benefits (e.g., increase peer support, parents to turn off the TV, organised activities at school, restructure physical education classes to allow student involvement in the decision-making process of class content). No ethnic and few sex differences in perceptions were found. Focusing on the verbalised importance of social support from the focus groups, Project 3 data showed that the strength of association between perceived encouragement from different support sources (i.e., parents, older siblings/cousins, peers, school) and physical activity participation varied by the physical activity opportunity examined. In particular, multivariate logistical regression showed reduced odds of being in the ‘more active’ group was associated with low parental encouragement (Juniors, OR: 0.47, 95% CI: 0.38-0.58; Seniors, OR: 0.41, 95% CI: 0.29-0.60) and low peer encouragement (Juniors, OR: 0.61, 95% CI: 0.51-0.74; Seniors, OR: 0.49, 95% CI: 0.35-0.69) for after-school physical activity, low peer encouragement (Juniors, OR: 0.39, 95% CI: 0.32-0.48; Seniors, OR: 0.41, 95% CI: 0.29-0.57) for lunchtime activity, and low peer encouragement (Juniors, OR: 0.78, 95% CI: 0.66-0.92) for active transportation (junior students only). No significant difference in physical activity was found between students who received high encouragement from two parents than students who reported high encouragement from their sole parent in a single parent family. Concentrating on the after-school period, Project 3 data were analysed to examined the relevance of the displacement hypothesis during this school-day period. The association between parental strategies (i.e., encouragement to be active and having TV limits) and youth after-school activity behaviours (i.e., hours spent viewing TV, physical activity participation) was also examined. Support for the displacement hypothesis emerged. In particular, compared to students who watched less than one hour of TV, those who watched greater than four hours of TV were half as likely to be in the more active group for after-school physical activity participation (adjusted OR: 0.51; 95% CI: 0.40-0.65). Comparing activity profile groups (i.e., based on combined TV use and after-school activity levels), compared to the participants in the ‘low TV/active’ group, participants in the other three activity groups (e.g., ‘high TV/low active’) were at least 1.28 times more likely to have parents that executed only one parental strategy and up to 4.77 times more likely to have parents that did not carry out either strategy. Substantive opportunities exist for youth to be active every day, and in different contexts and environments, yet a large proportion of young people are not maximising these opportunities to be active. If the health issue of inactivity is to be tackled in a comprehensive and efficient manner, a multi-strategy, multi-environment, coordinated approach among local authorities, government agencies, schools, families, and neighbourhoods is required to address the noted policy, physical, and social-related associates of an active lifestyle for youth. Future effort, whether in the form of strategy development, intervention work, or research, needs to be founded upon ecological theory, where both individual and a range of familial, social, and physical environmental factors (and there potential interactions) are considered. Lastly, equal research attention should be directed at improved physical activity levels, and just as importantly, reducing time youth spend in a sedentary state.
