Complexity Conceptual Perspectives for Research About Educational Complex Systems

Abstract

This article is premised on the observation that in educational research there is an increasing use of terminology and concepts related to the field of complexity and the study of complex physical, biological, and social systems. As we are at an early stage in this cross-fertilization of complex systems ideas and methods in educational research, this article provides an overview of key complex systems conceptual perspectives and research methods in conjunction with a discussion of why educational researchers should consider their use. It is hoped that this overview of complex systems concepts and nomenclature used to describe research that views education as a complex system will help promote a broader awareness and acceptance of this work in the educational research community.     

Peer group interaction of physically abused children

The aim of this research study was to test the assumption that physically abused children differ significantly from their non-abused peers along dimensions which characterize abusing adults and other social deviants. Nineteen 5-10 year-old physically abused children and 38 non-abused peers were assessed by video-taped behavioral observations during free-flowing social interaction in a playroom. The dimensions tapped were: aggression, warmth, fear, pleasure, concentration, imagination and social participation. The dimension social participation was split into three variables: total social participation, negative participation and positive participation. The data from these nine dimensions was subject to a Pearson's correlation. Given the high correlation amongst these variables the data was subject to a principal components analysis with varimax rotation. From this analysis two components emerged which explained 76.9% of the total variance. These components were designated "social interaction" (component 1) and "hostility" (component 2) and were then subject to analyses of variance. A significant difference was found between the two groups on the "social interaction" component. The implications of these findings were explored and treatment possibilities examined.

Preparing for the Inevitable: Training Social Workers to Cope with Client Suicide

Little attention has been given to educating and training social work students and professionals about working with suicidal clients. This article summarizes the literature on client suicide and the professional social worker, as well as presents results from a mixed methods study, which utilized both qualitative and quantitative data collected from a national study on client suicide among social workers. The results indicate that 55% of social workers will experience at least one client suicide attempt and 31% will experience a client suicide completion during the course of their career. Additionally, less than 50% of the social workers surveyed received previous training or education about client suicide in their MSW programs. Suggestions from social workers for the content of training classes on client suicide are included. Implications for practice and research are also discussed.     

Students' Perceptions of Teaching in Context-based and Traditional Chemistry Classrooms: Comparing content,learning activities,and interpersonal perspectives

Context-based curriculum reforms in chemistry education are thought to bring greater diversity to the ways in which chemistry teachers organize their teaching. First and foremost, students are expected to perceive this diversity. However, empirical research on how students perceive their teacher's teaching in context-based chemistry classrooms, and whether this teaching differs from traditional chemistry lessons, is scarce. This study aims to develop our understanding of what teaching looks like, according to students, in context-based chemistry classrooms compared with traditional chemistry classrooms. As such, it might also provide a better understanding of whether teachers implement and attain the intentions of curriculum developers. To study teacher behaviour we used three theoretical perspectives deemed to be important for student learning: a content perspective, a learning activities perspective, and an interpersonal perspective. Data were collected from 480 students in 24 secondary chemistry classes in the Netherlands. Our findings suggest that, according to the students, the changes in teaching in context-based chemistry classrooms imply a lessening of the emphasis on fundamental chemistry and the use of a teacher-centred approach, compared with traditional chemistry classrooms. However, teachers in context-based chemistry classrooms seem not to display more ‘context-based’ teaching behaviour, such as emphasizing the relation between chemistry, technology, and society and using a student-centred approach. Furthermore, students in context-based chemistry classrooms perceive their teachers as having less interpersonal control and showing less affiliation than teachers in traditional chemistry classrooms. Our findings should be interpreted in the context of former and daily experiences of both teachers and students. As only chemistry is reformed in the schools in which context-based chemistry is implemented, it is challenging for both students and teachers to deal with these reforms.     

The literacy achievement of Norwegian minority students

The article presents the literacy achievement of Norwegian minority students, their reading habits, and their enjoyment of reading based on the Programme for International Student Assessment (PISA) 2000 study. Aspects of their family background and attitudes towards school are related to literacy achievement results. A comparison between Denmark, Sweden, Norway and Germany shows that the achievement gap between majority and minority students is larger in Denmark and Germany than in Norway and Sweden. A more detailed presentation of the Norwegian reading results shows that 35% of the Norwegian minority students perform at a level indicating that they are able to read in a technical sense, but they are unlikely to be able to use reading as an independent tool in acquiring knowledge and skills. The minority students' responses to questions about socio‐economic family background, reading habits, learning strategies and school motivation give a complex picture of their situation in Norwegian schools. The results indicate that there is some potential for equalising differences between minority students and majority students.     

Gender Differences in Computer-related Control Beliefs and Home Computer Use

This study explores gender differences in home computer use and control beliefs relative to being able to use computers. Perceived control of computer usage was measured in 152 Grade 8 Norwegian students. One group of students ( n = 58) had no computer training and did not use computers at school. In this group, males were found to have greater perceived control of the computer as well as greater confidence in own success, compared with females. Another group of students ( n = 94) had computer training in school. No gender differences were found in this group. The results are discussed in terms of sex stereotypes and the impact of computer training.     

Sleep and stress hormone responses to training and competition in elite female athletes

Stress hormone and sleep differences in a competition versus training setting are yet to be evaluated in elite female team-sport athletes. The aim of the current study was to evaluate salivary cortisol and perceptual stress markers during competition and training and to determine the subsequent effects on sleep indices in elite female athletes. Ten elite female netball athletes (mean?±?SD; age: 23?±?6 years) had their sleep monitored on three occasions; following one netball competition match (MATCH), one netball match simulation session (TRAIN), and one rest day (CONTROL). Perceived stress values and salivary cortisol were collected immediately pre- (17:15 pm) and post-session (19:30 pm), and at 22:00 pm. Sleep monitoring was performed using wrist actigraphy assessing total time in bed, total sleep time (TST), efficiency (SE%), latency, sleep onset time and wake time. Cortisol levels were significantly higher (p?p?p?相似文献   

Fostering Transit between Real World and Mathematical World: Some Phases on the Modelling Cycle

This study shows how, in the initial training of mathematics teachers, it is possible to promote processes of abstraction and mathematisation through modelling a real situation with the support of auxiliary material to mediate understanding. By adapting elements of the theoretical and methodological framework called Abstraction in Context (AiC), participants’ discussions while building a mathematical model—in a nested epistemic actions—are analysed. Two specific points are discussed in this paper. The first aims to identify how different types of knowledge emerge when an individual is faced with a modelling task. The second is regarding the use of auxiliary material as a means of metaphorising a situation. It was evidenced how the material favours the construction of a mathematical model through the simplification and idealisation that it brings. The meaning constructed for the model is supported in recognising a decreasing behaviour as a part of a whole.
