The Resilient Survivor—A Student Social Worker's Journey on Placement

This paper represents the continuation of my ‘personal and professional journey’ from social work student to social work practitioner focusing on my first Practice Learning Opportunity (PLO). Recognising the potential impact of childhood sexual abuse (CSA) in a classroom environment is as important as the potential impact on actual practice learning and practice. This is salient in the real world of social work practice as the potential misuse of a painful childhood experience has greater ramifications. Utilising the ideas and assumptions of social constructionism (including context and multivocality) the significance of silence from social work educators shall be examined in relation to self-disclosure as a means of aiding PLO learning and practice. This paper will also focus on the concept of critical reflection and its significance in exploring the transferability of a childhood experience such as CSA and personal and professional dilemmas regarding self-disclosure. This paper concludes by highlighting areas for consideration for both students and social work educators and conveys an important message regarding the importance of communication between students and social work educators.     

Effects of critical incident tasks on the intercultural competence of English non-majors

ABSTRACT

In this internationalised world, graduate employability in terms of intercultural communication skills needs to be taken into account in higher education. The present study aims to explore the effects of critical incident task instruction on English non-majored undergraduates’ intercultural competence. One group of students received ten weeks of instruction with one critical incident task per week and another group received standard English classes. Data were collected from the students’ pre- and post-test. The results showed a significant and strong effect of the intervention with critical incident tasks. Implications for educational practice are presented for further teaching with critical incident tasks.     

Assumptions,conjectures, and other miracles: The application of evaluative thinking to theory of change models in community development

Unexamined and unjustified assumptions are the Achilles’ heel of development programs. In this paper, we describe an evaluation capacity building (ECB) approach designed to help community development practitioners work more effectively with assumptions through the intentional infusion of evaluative thinking (ET) into the program planning, monitoring, and evaluation process. We focus specifically on one component of our ET promotion approach involving the creation and analysis of theory of change (ToC) models. We describe our recent efforts to pilot this ET ECB approach with Catholic Relief Services (CRS) in Ethiopia and Zambia. The use of ToC models, plus the addition of ET, is a way to encourage individual and organizational learning and adaptive management that supports more reflective and responsive programming.     

Task-based learning approaches for supporting the development of social science researchers’ critical data skills

Conducting social science research is a complex process, and social science students face a number of learning challenges in order to develop their skills. Moreover, new sources and types of data including so-called big data are providing new opportunities for research, but also pose methodological challenges. In this article, we explore a task-based learning approach for teaching social science research methods. We draw on evidence from two case study learning tasks: (i) the collection and analysis of Twitter data; and (ii) designing and conducting a face-to-face and online survey. The students were guided to co-lead the tasks, apply their knowledge and then to critically reflect. The pedagogical framework of task-based learning provides opportunities to embed learning in new ways by integrating knowledge, practice and critical reflection. Task-based learning can create a dynamic learning environment and can empower students to develop their identities as researchers.     

农村校车安全事故背后的教育公平问题

近年来农村校车事故频发,使得校车安全问题浮出了水面。其实,校车不够规范只是校车事故频发的表层原因,而更深层次的原因却在于城乡教育资源配置的不公平。所以要解决校车安全问题,不仅在于规范校车、提高校车的质量,还在于合理配置教育资源,实现城乡教育公平。     

Falsificationism is not just ‘potential’ falsifiability,but requires ‘actual’ falsification: Social psychology,critical rationalism,and progress in science

Based on an analysis of ten popular introductions to social psychology, we will show that Karl Popper's philosophy of ‘critical rationalism’ so far has had little to no traceable influence on the epistemology and practice of social psychology. If Popper is quoted or mentioned in the textbooks at all, the guiding principle of ‘falsificationism’ is reduced to a mere ‘falsifiability’ and some central elements of critical rationalism are left out – those that are incompatible with positivism and inductivism. Echoing earlier attempts to introduce Popper to social psychology by Paul Meehl and Tom Pettigrew, we will argue that a discussing Popper's ideas in more depth could help social psychology to move forward in view of the ‘crisis of confidence’ (Pashler and Wagenmakers, 2012) that has emerged recently in view of the ‘Stapel affair’ and the reports of failures to replicate social psychological experiments in high‐powered replication attempts.

Traditional,Problem-Solving and Critical Theory: An Analysis of Horkheimer and Cox's Setting of the ‘Critical’ Divide

Abstract

Robert W. Cox's dictum that ‘(t)heory is for someone and for some purpose’ (emphasis in the original) is said to be the most-quoted line in International Relations (IR) theory. Yet whilst this spurred a revolution in critical thinking in IR, it echoed a far older conception of Critical Theory advanced by Max Horkheimer in the 1930s that claimed there is ‘no theory of society?…?that does not contain political motivations'. Both sentiments emphasize the relation between knowledge and human interests, and yet both formulate two distinct—though allied—ways of approaching ‘critical’ theorizing. In order to understand the similarities and differences in their approaches, this paper draws out three loci of difference between Cox and Horkheimer regarding the question of emancipation: (i) the epistemological relation between ‘critical’ and ‘Problem-Solving’ (Cox) or ‘Traditional Theory’ (Horkheimer); (ii) the emphasis placed on transformation and historical process; and (iii) the importance of intersubjectivity in how each approach emancipation. It is argued that by actively combining critical (dialectical) approaches across the social sciences, broadening human agency through civilizational dialogue, and retaining a commitment to emancipatory (and visionary) political futures based on human association, that Critical International Theory can maintain ongoing relevance in IR.
