Components of Conceptual Ecologies

The theory of conceptual change is criticized because it focuses only on supposed underlying logical structures and rational process processes, and lacks attention to affective aspects as well as motivational constructs in students’ learning science. This is a vast underestimation of the complexity and diversity of one’s change of conceptions. The notion of conceptual ecology provides a context for understanding individuals’ conceptual change learning, as it is the environment through which all information is interpreted. This research investigated how high school students’ statements, made in answering questions, reflect selected components of their conceptual ecologies. Data for this study was collected from six interviews in which seven students took part. The data also include the science teacher’s profiles of each student, the students’ personal journals, their assignments, and their examinations and answers in class. The analysis presented will here include only those components that were represented in the discourse of the seven high school students who were interviewed. When students were asked questions, there was evidence of the engagement of the various components of conceptual ecologies. These components include: epistemological commitments, metaphysical beliefs, the affective domain and emotional aspects, the nature of knowledge, the nature of learning, the nature of conceptions, and past experience. Evidence from this study suggests that these components might function as constraints to learning. This study contributes to the field by expanding our knowledge of the components of high school students’ conceptual ecologies through its definition of the categories and themes associated with those components. In examining across the range of components, the study illustrates the variety and sources of science conceptions within high school students’ conceptual ecologies.     

Influential factors for knowledge creation practices of CTE teachers: mutual impact of perceived school support, transformational leadership, and work engagement

This study examined the structural relationships among perceived school support, transformational leadership, teachers’ work engagement, and teachers’ knowledge creation practices. It also investigated the mediating effects of transformational leadership and work engagement in explaining the association between perceived school support and knowledge creation practices. Samples included 284 career and technical education teachers in the United States. Structural equation modeling was employed. Perceived school support was positively associated with transformational leadership and teachers’ work engagement, but had no direct impact on knowledge creation practices. Transformational leadership was found to affect knowledge creation practices, but not work engagement of teachers. Although a supportive school climate had no direct relationship with knowledge creation practices, it indirectly affected this outcome variable through transformational leadership and teachers’ work engagement. The results suggest that in order to increase teachers’ knowledge creation activities, a supportive school climate should be provided with efforts to improve teachers’ work engagement and transformational behaviors of the principal.     

The Politics of Emotions in ELT: Structure of Feeling and Anxiety of Korean English Teachers

ABSTRACT

Using the notion of structure of feeling by Raymond Williams, this article seeks to illuminate an ideological understanding of Korean English teachers’ anxiety and deep sense of insecurity in English language teaching (ELT). Through a discussion of how their anxiety is grounded deeply within unequal social relations and how they reframe their anxiety through critical reflection on the cultural and ideological bias of their own anxiety, it points out the intricate relationship between ideology and emotion; teachers’ emotions are shaped by dominant ideologies that constitute the social structures constraining their position as teachers, while their engagement with those emotions also enables their self-transformation towards gaining confidence as teachers. The results of the study emphasise the tension between social structure and agency in teachers’ emotional experiences and discuss implications for teacher education and development.     

The factors of child physical abuse in Korean immigrant families

OBJECTIVE: This study explores Korean immigrant mothers' attitudes toward child physical abuse based on an ecological perspective. METHOD: One hundred and forty-four Korean immigrant mothers who came to the US after age 16 and have at least one child under 18 years old participated in this study. Data were collected using instruments translated in Korean that measure mothers' attitudes toward child physical abuse in four areas: degree of agreement with physical abuse, conflict tactics, belief in the use of physical punishment, and perceptions regarding physical abuse. RESULTS: This study found that the following variables affect Korean immigrant mothers' attitudes toward child physical abuse at ecological levels of the environment: amount of time spent with children, experience of corporal punishment as a child, children's gender and age, family acculturation conflicts, mothers' age, and length of time in US at the micro level; involvement in their children's school and involvement in social organizations at the meso level; level of education and reported stress of immigrant life at the exo level; value of children in Korean culture, familiarity with Child Protective Services (CPS), perceived discrimination, and value of corporal punishment at the macro level. CONCLUSIONS: This study suggests the importance of cultural sensitivity in social work practice when working with Korean immigrants. It also implies that intervention and prevention efforts of child abuse should be targeted at more than one level of the environment.

Examining the effect of positive behaviour support on academic achievement of students with disabilities

Students who engage in challenging behaviour compromise the fundamental ability of schools to educate children. Consequently, teachers face the daunting task of designing effective strategies to promote positive educational outcomes for their students. Since the 1997 Individuals with Disabilities Education Act amendments, the use of positive behaviour supports (PBS) to address the behavioural needs of children challenged by disabilities has expanded. There is evidence to support the utility of PBS in reducing challenging behaviour among students. However, successful schools are also gauged by the academic achievement of their students. Hence, it is important to examine the extent to which behavioural outcomes are related to academic outcomes. The purpose of this paper is to examine the extent to which PBS interventions aimed at reducing challenging behaviour result in corresponding improvement in academic achievement. A meta‐analysis of extant research indicated a positive correlation of 0.40 between improvement in problem behaviour and academic achievement.

FIRST YEAR IMPLEMENTATION OF A PROJECT-BASED LEARNING APPROACH: THE NEED FOR ADDRESSING TEACHERS�� ORIENTATIONS IN THE ERA OF REFORM

The purpose of this study was to examine the extent to which three teachers’ professional experience and existing orientations toward teaching and learning mathematics and science influenced their implementation of a project-based curriculum (i.e. project-based learning (PBL)). Data sources included interviews, videotapes of classroom activity, and a teaching philosophy questionnaire. Data analysis was conducted using an iterative coding technique. We found coherency between the teachers’ perceived orientations and their emergent ideas about PBL, their sense of PBL as being compatible with their goals, and the specific challenges with which they struggled. All the teachers wanted their students to be successful; however, different definitions of success led to quite different approaches toward teaching, and for the most part, these differences appeared to have occurred because of existing orientations the teachers held for teaching their discipline. Implications for professional development taking into account teachers’ orientations and thus their professional experience are discussed, as well as disciplinary challenges to using PBL.     

Goethe’s Conception of “Experiment as Mediator” and Implications for Practical Work in School Science

There has been growing criticism over the aims, methods, and contents of practical work in school science, particularly concerning their tendency to oversimplify the scientific practice with focus on the hypothesis-testing function of experiments. In this article, we offer a reading of Johann Wolfgang von Goethe’s scientific writings—particularly his works on color as an exquisite articulation of his ideas about experimentation—through the lens of practical school science. While avoiding the hasty conclusions made from isolated experiments and observations, Goethe sought in his experiments the interconnection among diverse natural phenomena and rejected the dualistic epistemology about the relation of humans and nature. Based on a close examination of his color theory and its underlying epistemology, we suggest three potential contributions that Goethe’s conception of scientific experimentation can make to practical work in school science.     

Using log variables in a learning management system to evaluate learning activity using the lens of activity theory

As the advance of learning technologies and analytics tools continues, learning management systems (LMSs) have been required to fulfil the growing expectations for smart learning. However, the reality regarding the level of technology integration in higher education differs considerably from such expectations or the speed of advances in educational technologies. This research aimed to evaluate the current activation levels and usage patterns of a LMS. A large data-set was analysed, which included the online activity information from 7940 courses. Through data pre-processing, general indicators reflecting login frequencies of the virtual campus and activity-based indicators presenting the activation patterns of diverse functions provided by Moodle were derived. Activity theory was applied to interpret the results of analysis, since it has been recognised as a powerful framework to understand phenomena encompassing interactive systems. Further, time-series investigation over three consecutive semesters allowed observation of historical changes. The results revealed considerably low use of the virtual campus with only slight changes, as well as significantly different activity patterns across course attributes and colleges. Contradictions among components in the activity system are discussed, along with the implications for improving teaching and learning with LMS in higher education.
