Facilitating change in undergraduate STEM instructional practices: An analytic review of the literature

This article reviews current scholarship about how to promote change in instructional practices used in undergraduate science, technology, engineering, and mathematics (STEM) courses. The review is based on 191 conceptual and empirical journal articles published between 1995 and 2008. Four broad categories of change strategies were developed to capture core differences within this body of literature: disseminating curriculum and pedagogy, developing reflective teachers, enacting policy, and developing shared vision. STEM education researchers largely write about change in terms of disseminating curriculum and pedagogy. Faculty development researchers largely write about change in terms of developing reflective teachers. Higher education researchers largely write about change in terms of enacting policy. New work often does not build on prior empirical or theoretical work. Although most articles claim success of the change strategy studied, evidence presented to support these claims is typically not strong. For example, only 21% of articles that studied implementation of a change strategy were categorized as presenting strong evidence to support claims of success or failure of the strategy. These analyses suggest that the state of change strategies and the study of change strategies are weak, and that research communities that study and enact change are largely isolated from one‐another. In spite of the weak state of the literature, some conclusions related to the design of change strategies can be drawn from this review. Two commonly used change strategies are clearly not effective: developing and testing “best practice” curricular materials and then making these materials available to other faculty and “top‐down” policy‐making meant to influence instructional practices. Effective change strategies: are aligned with or seek to change the beliefs of the individuals involved; involve long‐term interventions, lasting at least one semester; require understanding a college or university as a complex system and designing a strategy that is compatible with this system. © 2011 Wiley Periodicals, Inc.

An online categorization task to investigate changes in students' interpretations of organic chemistry reactions

In this study, we investigated how students organized their knowledge about organic chemistry reactions in a transformed curriculum, including their choices, abilities, and changes over time. This transformed curriculum focuses on interpreting the underlying mechanistic patterns of chemical reactions and emphasizes the principles of reactivity in organic chemistry. Data from this study were collected at beginning and end of an Organic Chemistry II course using an open and closed online categorization task with a set of organic chemistry reactions. In the open task, participants organized the set of reactions as they chose, giving us insight into how the participants preferred to organize their knowledge. In the closed task, participants were asked to organize the set of reactions in a specific way—by each reaction's governing mechanism—which would provide a measure of the students' ability to categorize the reactions in that way. We investigated the similarities and differences of the open and closed categorizations at each time of administration and analyzed the changes over time. Findings from this study emphasized the efficacy of the transformed curriculum for: (a) promoting a focus on process-oriented features of reactions over static features of a reaction and (b) increasing the students' abilities to categorize a set of reactions according to the mechanism governing the reaction. Findings revealed implications for the transformed curriculum, which addresses key areas for improvements, potential implications for research, and also limitations of the current study. We further describe possible extensions of this study to how the open and closed categorization tasks may be used for research and instruction in other science, technology, engineering, and math disciplines.

Teaching about ethics through socioscientific issues in physics and chemistry: Teacher candidates' beliefs

The purpose of this qualitative study was to identify and explain the origins of physics and chemistry teacher candidates' beliefs about teaching about ethics through socioscientific issues (SSI). This study utilized a series of in‐depth interviews, while the participants (n = 12) were enrolled in a 9‐month teacher education program at an urban university in Canada. Our data analysis revealed that beliefs about teaching physics and chemistry using SSI derive from a complex web of fundamental beliefs exemplified by four archetypes representing the subject‐specific identities of our teacher candidates—Model Scientist/Engineer, Model Individual, Model Teacher, and Model Citizen. Furthermore, we found that the justification for belief change required by a particular teacher candidate depends on these subject‐discipline identities. Thus, the presence of each archetype in preservice classrooms has ramifications for the way a teacher educator should encourage his or her students to include SSI in their teaching. © 2009 Wiley Periodicals, Inc.

Confronting assumptions,biases, and stereotypes in preservice teachers' conceptualizations of science teaching through the use of book club

This study focuses on the structure and theoretical foundations of the book club for promoting multicultural understandings in science teacher education. The book club was defined as an informal, peer‐directed group discussion that met regularly to discuss an ethnographic, multicultural text regarding issues pertinent to science teaching and learning in urban classrooms. Twenty‐three preservice teachers (PSTs) enrolled in a 16‐week elementary science methods course at a large urban university participated in the study. From the qualitative analyses of PSTs' written reflections and researcher journal notes, five themes which emphasize Individual, Collaborative, and Collective learning are presented. These findings highlight how the book club structure and theoretical foundation fostered critical, reflective inquiry and served as a method for effecting ideological change which is needed in order to embrace issues of diversity in urban science education. Implications for science teacher education concerning the relevancy of pedagogical strategies, the use of multiple theoretical perspectives, and the book club as a strategy in teacher education and urban education are discussed. © 2009 Wiley Periodicals, Inc.

Transversal traits in science education research relevant for teaching and research: A meta‐interpretative study

This study is a meta‐interpretative analysis that focuses on research conducted and published by other researchers. Concepts central to this study include global practical relevance, curriculum design, and formative situation. We analyzed 35 studies selected from 374 published studies in the years 2000 and 2001 in three journals referenced in the International Scientific Index. Using a replicable methodology developed specifically for this research, we found evidence of s clusters of variables that suggest the existence of transversal traits in the 35 science education research studies. These results form a reference framework of theoretical and practical knowledge relevant for research and practice pertaining to teaching and learning science. © 2008 Wiley Periodicals, Inc.

Teaching in the borderland: critical practices in foundations courses

Using first-person accounts of classroom experiences, five professors examine the intersection of social foundations and borderland theory and their efforts to move students through resistance to understanding and affirmation of sociocultural diversity. The authors present this paper in two parts, the first providing examples of using a borderland approach within the classroom and the second providing illustrations moving these borderland strategies beyond the classroom. In each case, authors show the interwoven nature of pedagogy, identity, knowledge, and experience as they work to connect theory and practice. All of the institutions represented have majority white populations, and many do not reflect the diversity of the communities in which they are situated. The need for borderland practices in social foundations courses is urgent in these areas. These pedagogical reflections, although not meant to be recipes for success, provide examples of practices that can serve to meet the growing demands from schools and communities for culturally competent, socially aware teacher–leaders, and reaffirm the critical importance of social foundations in teacher education.

Seeking effectiveness and equity in a large college chemistry course: an HLM investigation of Peer‐Led Guided Inquiry

This study employed hierarchical linear models (HLM) to investigate Peer‐Led Guided Inquiry (PLGI), a teaching practice combining cooperative learning and inquiry and tailored for a large class. Ultimately, the study provided an example of the effective introduction of a reform pedagogical approach in a large class setting. In the narrative, the strengths of HLM as a statistical technique are discussed in the context of pedagogical reforms, and the case is made for the use of HLM in rigorous determinations of both effectiveness and equity associated with reform practices. The implementation of PLGI in a college‐level general chemistry course is also described. For the study, two general HLM models suited to investigating reform were developed and utilized to examine the effectiveness and equity of PLGI as implemented in this setting. The models showed that the reform was associated with statistically significant improvement over traditional pedagogy in terms of academic performance on multiple measures, but achieving equity remained elusive: the consequences of pre‐existing achievement gaps did not lessen as a result of reform implementation. The analysis led to several implications for educational research, particularly in terms of evaluating pedagogical reforms, as well as for teaching. Choosing effective and equitable pedagogies for classroom implementation remains a critical goal for classes of any size. © 2008 Wiley Periodicals, Inc. J Res Sci Teach 45: 794–811, 2008     

Participatory action research as pedagogy: investigating social and ecological justice learning within a teacher education program

A research collective comprised of teacher candidates, graduate students, and faculty set out to investigate the role and impact of social and ecological justice learning in a teacher education program. Amidst the tensions, negotiations, and articulations of the research design, the collective came to recognize the spaces of participatory action research as sites of growth and efficacy toward justice learning. And, each began to perceive themselves as both impacted by educational structures and as agents enacting their own visions of professional practice. These outcomes are discussed in the context of the growing body of participatory action research, emphasizing the dynamic learning precipitated within the intersections of the research collective. The empirical analysis, involving survey and interview data, brought to bear the rarity of events participants (teacher candidates) recognized as invoking meaningful social and ecological justice learning, and goes some way to describe such learning in terms of embodied experience. The paper closes with a selection of testimonials provided by members of the research collective, offering personal accounts of what was gained through participating in the research process.     

Non-traditional students in tertiary education: inter-disciplinary collaboration in curriculum and pedagogy in community services education in Australia

Education policy in Australia has accelerated its aim to increase participation of under-represented groups in tertiary education including students who are culturally and linguistically diverse and have low socio-economic status. These students generally have not had prior access to privileged academic discourse, which can further disadvantage them in their participation and progress in tertiary education. In this article, we outline a cross-discipline curriculum initiative and pedagogy that draws on critical literacy and the metaphor of discourse community to integrate language and academic skills into community services qualifications. We argue that this – supports the genuine participation of under-represented (non-traditional) students. It aspires to not only support students’ entry into the new academic terrain, but to enable students to adopt a critical stance to the discourses in which they are learning to participate. This we argue is crucial, when expertise is not just a way of meeting its ostensible purposes, but is also a way of exercising power. Although we report on the application of this initiative to entry level curricula (Diploma), we suggest that it has relevance and application to Bachelor levels in a range of disciplines, both in supporting pedagogy and for transition to Bachelor level study.     

Teacher collaborative inquiry in the context of literacy education: examining the effects on teacher self-efficacy,instructional and assessment practices

This case study research reports on elementary (grade 8) and secondary school (grade 9) teachers’ participation in job-embedded, professional learning and engagement in collaborative inquiry. Teachers constructed an inquiry-oriented media literacy unit following the collaborative inquiry model. The current study sought to investigate how collaborative inquiry influenced their self-efficacy in literacy instruction, instructional and assessment practices. Qualitative data sources included researchers’ anecdotal notes, teacher interviews, and professional learning blog conversations. Inductive analyses of the data generated six major themes comprising enhancements to teachers’ literacy instructional and assessment practices, which were evident in their adoption of the backward-design model, use of success criteria, and greater emphasis on diagnostic and formative assessment. With respect to teachers’ self-efficacy, data analyses also revealed increased levels of intrinsic motivation, professional satisfaction, and reflective practice. This study provides evidence for the transformative potential and characteristics of school-based teacher collaborative inquiry and the resultant impacts on teacher learning.     

Beyond rote learning in organic chemistry: the infusion and impact of argumentation in tertiary education

ABSTRACT

There exists bias among students that learning organic chemistry topics requires rote learning. In this paper, we address such bias through an organic chemistry activity designed to promote argumentation. We investigated how pre-service science teachers engage in an argumentation about conformational analysis. Analysis of the outcomes concentrated on (a) pre-service teachers’ understanding of conformations of alkanes (b) the nature of the pre-service teachers’ discourse; (c) the quality of pre-service teachers’ argumentation; and (d) pre-service teachers’ spatial ability. Various measures were used to trace (a) conceptual understanding through the answers in the writing frames, (b) the nature of the pre-service teachers’ discourse using two different codes, (c) the quality of pre-service teachers’ argumentation by counting the number of episodes with higher-level argumentation, and (d) spatial ability by Spatial Ability Test. The results showed that high performing groups had multiple rebuttals in their argumentation and low performing groups had problems in evaluating the credibility of evidence. Furthermore, we observed that spatial abilities play an important role in pre-service teachers’ engagement in argumentation. The findings help understanding of how to further enhance pre-service teachers’ conceptual understanding and engagement in argumentation regarding organic chemistry concepts.     

Using Reflective Journals to Enhance Impoverished Practicum Placements: A case in teacher education in Ethiopia

This article investigates the value of writing reflective journals for student teachers during practicum placement. The author invited 10 pre‐service education degree teachers to write a weekly reflective journal throughout their four weeks practicum teaching. Each student teacher was given the opportunity to revisit the issues in his journals through a subsequent reflective dialogue. At the end of the practicum, the student teachers were asked to complete one additional reflective journal to provide their views about how useful and challenging they found the task of writing reflective journals on their teaching experiences. The author also kept observation notes to reflect on his own experiences of involving student teachers in reflective journal writing. It was concluded that the student teachers benefited immensely from their experiences of writing reflective journals for the purpose of reflecting on their practical experiences. They reported that the activity helped them improve their teaching experiences and deepen their understanding of the complexities involved in learning to teach. The study has implications on the role of reflective journals as a means of engaging teacher candidates in reflective thinking, a recently emerging notion in the education of teachers in Ethiopia.     

The change in epistemological beliefs and beliefs about teaching and learning: a study among pre-service teachers

This study investigated the change in Singaporean pre-service teachers' epistemological beliefs and beliefs about learning and teaching over the course of a teacher preparation program. An online survey was administered during the first week of a nine-month program and the same survey was administered after the 413 participants had completed all their course work and teaching practice. Participants exhibited significant changes in epistemological beliefs and beliefs about learning and teaching – participants indicated more relativistic epistemological outlooks and less constructivism in beliefs about teaching. At the end of the teacher preparation program, they seemed to less value effort in learning and believed more in innate ability.     

Teacher-chameleons: the glue in the alignment of teacher practices and learning in policy

This article investigates how learning outcomes, a concept inspired by an Anglo-Saxon curriculum approach, are expressed in policy documents, with an emphasis on expectations articulated to teachers. Developments in education policy for the last two decades reflect a widespread expansion of learning outcome orientation in curricula and assessment in most of the modern world. These developments have led to changes in how education is governed and practised, and this makes it necessary to form critical concepts to understand how curricula are formed and functioned today. The research questions of the study are: How is learning outcome-oriented policy defined in key policy documents and what are the implications of these policies for the teaching profession? The topic is investigated through a document content analysis of key policy documents. A complex picture of teachers emerges in which they are to be both controlled and autonomous. The study also identifies a strong belief in ‘alignment between teachers’ competences and practices and students’ life opportunities. The findings indicate that the policies move back and forth between different parameters for describing teachers and teaching, and as such, teachers must be able to adapt as chameleons in the context of each policy.
