The development of elementary teacher identities as teachers of science

ABSTRACT

The purpose of this qualitative study was to investigate the contributions of pre-service teachers’ memories of science and science education, combined with their experiences in a STEM-focused teacher preparation programme, to their developing identities as elementary school teachers of science. Data collected over three years include a series of interviews and observations of science teaching during elementary teacher preparation and the first year of teaching. Grounded within a theoretical framework of identity and using a case-study research design, we examined experiences that contributed to the participants’ identity development, focusing on key themes from teacher interviews: memories of science and science instruction, STEM-focused teacher preparation programme, field experiences, first year of teaching, and views of effective science instruction. Findings indicate the importance of exposure to reform strategies during teacher preparation and are summarised in main assertions and discussed along with implications for teacher preparation and research.     

The Role of Informal Support Networks in Teaching the Nature of Science

This study reports the participation of 13 secondary science teachers in informal support networks and how that participation was associated with their nature of science (NOS) teaching practices 2 to 5 years after having graduated from the same science teacher education program. The nine teachers who participated in informal support networks taught the NOS at high/medium levels, while the four non-participating teachers taught the NOS at low levels. The nine high/medium NOS implementation teachers credited the informal support networks for maintaining/heightening their sense of responsibility for teaching NOS and for helping them navigate institutional constraints that impede effective NOS instruction. Several high/medium NOS instruction implementers initially struggled to autonomously frame and resolve the complexities experienced in schools and thus drew from the support networks to engage in more sophisticated forms of teacher decision-making. In contrast, the NOS pedagogical decisions of the four teachers not participating in support networks were governed primarily by the expectations and constraints experienced in their schools. Implications of this study include the need for reconsidering the structure of teacher mentorship programs to ensure they do not promote archaic science teaching practices that are at odds with reform efforts in science education.

     

The Pedagogical Orientations of South African Physical Sciences Teachers Towards Inquiry or Direct Instructional Approaches

In recent years, inquiry-based science instruction has become widely advocated in science education standards in many countries and, hence, in teacher preparation programmes. Nevertheless, in practice, one finds a wide variety of science instructional approaches. In South Africa, as in many countries, there is also a great disparity in school demographic situations, which can also affect teaching practices. This study investigated the pedagogical orientations of in-service physical sciences teachers at a diversity of schools in South Africa. Assessment items in a Pedagogy of Science Teaching Test (POSTT) were used to identify teachers’ science teaching orientations, and reasons for pedagogical choices were probed in interviews. The findings reveal remarkable differences between the orientations of teachers at disadvantaged township schools and teachers at more privileged suburban schools. We found that teachers at township schools have a strong ‘active direct’ teaching orientation overall, involving direct exposition of the science followed by confirmatory practical work, while teachers at suburban schools exhibit a guided inquiry orientation, with concepts being developed via a guided exploration phase. The study identified contextual factors such as class size, availability of resources, teacher competence and confidence, time constraints, student ability, school culture and parents’ expectations as influencing the methods adopted by teachers. In view of the recent imperative for inquiry-based learning in the new South African curriculum, this study affirms the context specificity of curriculum implementation (Bybee 1993) and suggests situational factors beyond the curriculum mandate that need to be addressed to achieve successful inquiry-based classroom instruction in science.     

Differences in teachers’ comments on classroom events as indicators of their professional development

This study aims at identifying indicators of schoolteachers’ professional development by learning teachers’ perceptual and thinking capabilities of classroom events as reflected in their comments. The analysis of comments produced by novice and expert teachers on videotaped lesson activities, based mainly on the grounded theory strategy, revealed that expert teachers are more sensitive towards certain instructional events and to general teaching strategy used by the model teacher than novice teachers. The findings of this study might be useful for promoting student teachers’ professional sensitivity towards relevant features of classroom instruction and atmosphere in pre-service teacher education programs.     

An Examination of Effective Practice: Moving Toward Elimination of Achievement Gaps in Science

This longitudinal study of middle school science teachers explored the relationship between effective science instruction, as defined by the National Science Education Standards (NRC in National science education standards. National Academy Press, Washington, DC, 1996), and student achievement in science. Eleven teachers participated in a three year study of teacher effectiveness, determined by the LSC Classroom Observation Protocol (Horizon Research, Inc. in Local Systemic Change Classroom Observation Protocol. May 1, 2002) and student achievement, which was assessed using the Discovery Inquiry Test in Science. Findings in this study revealed the positive impact that effective science teachers have on student learning, eliminating achievement gaps between White and Non-White students. Case studies of three teachers, both effective and ineffective explore the beliefs and experiences that influence teachers to change, or not to change practice. This study provides justification for teaching science effectively to narrow achievement gaps in science and provides insight to stakeholders in science education as to how to support teachers in becoming more effective, through addressing existing teacher beliefs and providing experiences that challenge those beliefs.     

Implications of a comparative assessment of exemplary and novice elementary teachers

Conclusion This study points to the fact that it would be practical to compare and assess the instructional strategies of exemplary and novice elementary science teachers using a set of criteria derived from published teacher effectiveness studies. According to this study there are differences ranging from significant to null between the instructional behaviors of exemplary and novice teachers, and it indicates that it may not be appropriate to rely entirely upon the findings of individual teacher effectiveness studies to prepare effective preservice teachers. Science teacher educators need to focus more directly on the differences in instructional strategies between the exemplary and novice teachers and inquire further into determining the causes for the differences. Hurd (1982) reported that about half of the elementary teachers studied believe that their preservice education failed to prepare them to teach science in real classrooms. If what separates exemplary teachers from novices can be clearly identified, then the science teacher educator’s task of preparing effective preservice teachers will be an easier one. Then it would be also possible to develop effective preservice science teacher education programs more congruent with exemplary science teaching practices and augment the existing science teacher education knowledge base through further research.     

Capturing teacher priorities: Using real-world eye-tracking to investigate expert teacher priorities across two cultures

Classroom teaching is complex. In the classroom, teachers must readily attend to disruptions and successfully convey new tasks and information. Outside the classroom, teachers must organise their priorities that are important for successful student learning. In fact, differing gaze patterns can reveal the varying priorities that teachers have. Teacher priorities are likely to vary with classroom expertise and can conceivably change with culture too. Therefore, the present study investigated expertise related and cultural teacher priorities by analysing their gaze proportions. To obtain this data, 40 secondary school teachers wore eye-tracking glasses during class time, with 20 teachers (10 expert; 10 novice) from the UK and 20 teachers (10 expert; 10 novice) from Hong Kong. We analysed gaze proportions during teachers' attentional (i.e., information-seeking, e.g., teacher questioning students) and communicative (i.e., information-giving, e.g., teacher lecturing students) gaze. Regardless of culture, expert teachers' gaze proportions revealed prioritisation of students, whereas novice teachers gave priority to non-instructional (i.e., not students, teacher materials, or student materials) classroom regions. Hong Kong teachers prioritised teacher materials (e.g., whiteboard) during communicative gaze whereas UK teachers prioritised non-instructional regions. Regarding culture-specific expertise, with Hong Kong experts prioritised teacher materials more than UK experts who, in turn, did so more than UK novices. We thus demonstrate the role of implicit teacher gaze measures as micro-level indicators of macro-level and explicit aspects of instruction, namely teacher priority.     

Novice teachers' encounter with national science education reform: Entanglements or intelligent interconnections?

This study centers on developing a structure and forum for novice teachers to explore science education reform documents and to link them to practice. To date, science education reform efforts have focused mainly on intended curricula (goals, standards, frameworks, etc.) and outcome-based measures (assessments). The implemented curriculum—the way teachers plan to teach—has received less attention. Moreover, the literature indicates that the gap between reform goals and practice can be attributed to the lack of attention to the implemented curriculum. In this project, 25 preservice and recently inducted science teachers analyzed the materials of Project 2061 or the National Research Council standards. A series of structured and interconnected activities allowed them to create summaries and an evaluation instrument, teachers' criteria, parallel to reform goals. Teams developed 10-day teaching units based on reform principles, then analyzed the products using the criteria they had developed. The study suggests some methods to help new teachers understand science education reform and create products that can be used for planning, teaching, and evaluation. © 1997 John Wiley & Sons, Inc.

The dilemma of dealing with persistent teaching traditions: findings of a video study

Nowadays, there is a consensus that good teaching and learning needs instructional variation and personalised forms of learning. In teacher education, these concepts have been implemented for years, and prospective teachers are taught accordingly; it is thus assumed that the teaching of novice teachers is in accordance with these new teaching concepts. In the research project ‘ALPHA’, the teaching of novice teachers at the beginning and at the end of their first year in the profession and the teaching of experienced teachers with five or more years of teaching experience was videotaped, so that longitudinal and cross-sectional comparisons were possible. The lessons were analysed by applying a coding system on the instruction and by employing a rater inventory in order to understand the structure and quality of the lessons. Overall, the results indicate high levels of whole class teaching with a rather high level of traditional classroom instruction both for the novice and the experienced teachers. However, the proportions vary depending on the location of teacher education. The results provide evidence that the new teaching concepts learned on the teacher education programme are not necessarily implemented in the classroom and provide possible reasons why this might be the case.     

The teaching of the philosophy of science in secondary classrooms: case studies of teachers’ personal theories

This study examines teachers’ philosophies of science and describes how these philosophies influence their classroom instruction. Three science teachers with very diverse views of science were interviewed and observed in their classrooms for several months. These teachers’ philosophies were found to influence laboratory instruction, the manner in which demonstrations were used, the teaching of evolution, science‐technology‐society (STS) instruction, word usage, and instructional goals. The findings are relevant to issues in teacher education as well as the institutional environment of teaching.     

Crossing the Border from Science Student to Science Teacher: Preservice Teachers’ Views and Experiences Learning to Teach Inquiry

Preservice science teachers face numerous challenges in understanding and teaching science as inquiry. Over the course of their teacher education program, they are expected to move from veteran science students with little experience learning their discipline through inquiry instruction to beginning science teachers adept at implementing inquiry in their own classrooms. In this study, we used Aikenhead’s (Sci Educ 81: 217–238, 1997, Science Educ 85:180–188, 2001) notion of border crossing to describe this transition preservice teachers must make from science student to science teacher. We examined what one cohort of eight preservice secondary science teachers said, did, and wrote as they both conducted a two-part inquiry investigation and designed an inquiry lesson plan. We conducted two types of qualitative analyses. One, we drew from Costa (Sci Educ 79: 313–333, 1995) to group our preservice teacher participants into one of four types of potential science teachers. Two, we identified successes and struggles in preservice teachers’ attempts to negotiate the cultural border between veteran student and beginning teacher. In our implications, we argue that preservice teachers could benefit from explicit opportunities to navigate the border between learning and teaching science; such opportunities could deepen their conceptions of inquiry beyond those exclusively fashioned as either student or teacher.     

Exploring teachers’ meta-strategic knowledge of science argumentation teaching with the repertory grid technique

ABSTRACT

This study investigated two science teachers’ meta-strategic knowledge (MSK) of argumentation teaching by applying the repertory grid technique (RGT). One teacher was a novice, while the other was experienced in teaching argumentation. Using the RGT, we elicited the objectives and strategies of the two teachers regarding their argumentation teaching involving two social scientific issue (SSI) scenarios. The results showed that the experienced teacher had more varied and organised MSK for teaching argumentation than the novice teacher. Meanwhile, the novice teacher indicated a belief that the learning of argumentation should occur in a more student-centred manner, rather than relying on a traditional lecture-based environment. Consequently, she spent a considerable amount of time engaging students with their peers’ ideas through discussion and collaboration. On the other hand, the experienced teacher noticed that most of students had the ability to generate arguments, but that few knew how to argue based on evidence. Therefore, she helped students to collect data from various resources and suggested that they construct their own knowledge framework in order to improve students’ ability to incorporate their understanding of scientific knowledge into scientific argumentation.     

Facilitating Primary Science Teaching: A narrative account of research as learning

This paper is, in part, a narrative account of a teacher educator's professional growth during a longitudinal case study of three primary science teachers, Katie, Jean and Ruth, as they made the transition from pre-service to inservice teaching. The study sought to explore ways in which the beginning teachers perceived and dealt with constraints to science teaching in the primary school, and how they changed and adapted the knowledge and skills developed at university in a practical situation. The findings of the study are organised by considering what we, the researchers, saw as three categories of challenge for these beginning primary science teachers, their initial alienation from the study of science, the differences between teaching science and teaching other subjects in the primary school, and the impact of novice status on science teaching. Working with participants to help them respond to these challenges became an occasion for our own development as science educators.     

Science Teachers Without Classrooms of Their Own: A Study of the Phenomenon of Floating

“Floating” teachers, or teachers without their own classroom, experience unique affordances and constraints as they develop professionally. To increase the knowledge in this area, this study looks at how traveling to different classrooms affects beginning secondary science teachers’ development and instruction. The participants in this study were three first-year floating secondary science teachers whose experiences were analyzed through a cultural historical activity theory framework. The data revealed how floating can either support or constrain the development of beginning science teachers, and limit the implementation of standards-based instruction. Finally, this study shows that high levels of human, physical, and social resources are necessary for progress towards standards-based science teaching. It suggests that if science teachers must move to different classrooms, we need to create ways in which to support their instruction and development. Furthermore, this study recommends that all teachers and supervisors work toward a deeper understanding of the school community’s role in the experience of the floating science teacher.     

Secondary science teachers' attitudes toward and beliefs about science reading and science textbooks

Science textbooks are dominant influences behind most secondary science instruction but little is known about teachers' approach to science reading. The purpose of this naturalistic study was to develop and validate a Science and Reading Questionnaire to assess secondary science teachers' attitudes toward science reading and their beliefs or informed opinions about science reading. A survey of 428 British Columbia secondary science teachers was conducted and 215 science teachers responded. Results on a 12-item Likert attitude scale indicated that teachers place high value on reading as an important strategy to promote learning in science and that they generally accept responsibility for teaching content reading skills to science students. Results on a 13-item Likert belief scale indicated that science teachers generally reject the text-driven model of reading, but they usually do not have well-formulated alternative models to guide their teaching practices. Teachers have intuitive beliefs about science reading that partially agree with many research findings, but their beliefs are fragmented and particularly sketchy in regard to the cognitive and metacognitive skills required by readers to learn from science texts. The findings for attitude, belief, and total scales were substantiated by further questions in the Science and Reading Questionnaire regarding classroom practice and by individual interviews and classroom observations of a 15-teacher subsample of the questionnaire respondents.     

A comparative study of the impact of enhanced input on inclusion at pre-service and induction phases on the self-efficacy of beginning teachers to work effectively with children with special educational needs

There is a well-founded assumption in the literature that the first year of teaching presents challenges to beginning teachers. However, few studies have looked empirically at how beginning teacher perceptions about teaching ability change from the pre-service to the novice teacher year. This is particularly the case for inclusive education, where no substantive empirical studies have measured such a change in teacher perceptions across these phases of teacher development. This study tracks changes in the perceived self-efficacy of teachers in relation to working effectively with children with special educational needs (n = 67) following an inclusion-enhancement programme in the pre-service phase and enriched induction on inclusion in the novice teacher phase. The study employed a repeated panel survey design with an intervention and comparison group. A critique is made of the domain specificity of current measures used for considering self-efficacy for inclusion, and an alternative approach proposed. Results indicate that there were relative gains in self-efficacy from the start to the end of the pre-service teacher year due to the enhancement programme, and that these gains were maintained in the novice teacher year. However, there was no evidence that the induction enrichment had any impact on self-efficacy in this domain. Implications for the timing and intensity of induction for beginning teachers, as well as for future research directions on teacher education, are considered.     

Research interests of secondary science teachers

In the past few years, science educators and the nation at large have become increasingly concerned about the “Crisis in Science Education.” An underlying cause of this crisis is the nonuniform quality of instruction delivered by secondary science teachers. One way to improve the quality of teaching in the schools is the application of science education research findings to teaching. Most teachers are unaware of the research findings and/or do not apply them in their classrooms. This study helps determine the areas of research which are of greatest interest to secondary science teachers. Results will be used by NSTA to determine the contents of future volumes of the monograph What Research Says to the Science Teacher. A random sample of 600 secondary science teachers was obtained from the National Registry of NSTA. Teachers were sent a 23 item questionnaire that asked them to rate their interest in each research topic on a five point scale. The questionnaire contained the 12 items prepared by a NARST-NSTA committee in 1979 and an additional 11 items using the same format. Demographic data collected from the survey included sex, teaching assignment, role in school, type of school, type of community, years of teaching experience, and familiarity with What Research Says. … Data were analyzed using this demographic data as well as according to whether teachers returned the original or a follow-up questionnaire. Teachers who returned the first questionnaire had basically the same preferences as those who returned the follow-up questionnaire. Sixty percent of the teachers completed the questionnaire in usable form. Overall results of the study based on both frequency of response and on mean rating indicate that the following five topics are of greatest interest to secondary science teachers: laboratory experiences, motivational techniques, effect on college courses, problem solving, and meaningful learning. Analysis of data according to the subject taught indicated that chemistry and physics teachers are more interested in problem solving than biology teachers, and that chemistry, physics, and earth science teachers are also interested in the sequence of the content. Males and females had the same top five interests but in a different order. The same is true for teachers of grades 7–9 versus grades 10–12. Rural teachers preferences varied substantially from those in other settings and differences were also found for teachers familiar with What Research Says … compared to the rest of the sample. For every classification of teacher, the area of least interest was sex difference research.
