Spatial thinking in science,technology, engineering,and mathematics: Elementary teachers' beliefs,perceptions, and self-efficacy

Fostering students' spatial thinking skills holds great promise for improving Science, Technology, Engineering, and Mathematics (STEM) education. Recent efforts have focused on the development of classroom interventions to build students' spatial skills, yet these interventions will be implemented by teachers, and their beliefs and perceptions about spatial thinking influence the effectiveness of such interventions. However, our understanding of elementary school teachers' beliefs and perceptions around spatial thinking and STEM is in its infancy. Thus, we created novel measures to survey elementary teachers' anxiety in solving spatial problems, beliefs in the importance of spatial thinking skills for students' academic success, and self-efficacy in cultivating students' spatial skills during science instruction. All measures exhibited high internal consistency and showed that elementary teachers experience low anxiety when solving spatial problems and feel strongly that their skills can improve with practice. Teachers were able to identify educational problems that rely on spatial problem-solving and believed that spatial skills are more important for older compared to younger students. Despite reporting high efficacy in their general teaching and science teaching, teachers reported significantly lower efficacy in their capacities to cultivate students' spatial skills during science instruction. Results were fairly consistent across teacher characteristics (e.g., years of experience and teaching role as generalist or specialist) with the exception that only years of teaching science was related to teachers' efficacy in cultivating students' spatial thinking skills during science instruction. Results are discussed within the broader context of teacher beliefs, self-efficacy, and implications for professional development research.     

Public dialogue with science and development for teachers of STEM: linking public dialogue with pedagogic praxis

Abstract

Despite evidence of quality teaching in Science, Technology, Engineering and Mathematics (STEM) subject domains and insistence on the part of many national governments on the economic value of STEM, education, recruitment and retention into STEM subject fields and occupations is said to be continually blighted by a ‘leaky pipeline’. In the UK context, schools are seen to benefit from a multitude of external STEM engagement and enrichment providers and initiatives. However, despite evidence of the positive impacts of STEM engagement on learners, there exists a dearth of understanding related to how principles of STEM engagement can facilitate STEM teachers in becoming more pedagogically innovative and relevant and, therefore, engaging of their learners in the classroom context. In this article, we employ a secondary data analysis of two prominent cases of public engagement in science and technology (PEST) in the UK to elicit combined lessons for STEM engagement and the pedagogical development of teachers. We consider the successes of science dialogue in establishing principles of best practice that might be transposed to the development of teachers as more able and effective in the engagement of learners in STEM.     

Creating a continuum of STEM models: Exploring how K-12 science teachers conceptualize STEM education

ABSTRACT

As more and more science teachers in the United States are now expected to implement STEM education in their classrooms, it is important to understand how teachers conceptualise STEM education. This information can then be used to provide teachers with meaningful support as they move towards implementation of STEM education. Understanding that not all representations of STEM are equal, this mixed-methods study used a phenomenographic lens to examine science teachers’ perceptions of eight different models of STEM education through photo elicitation interviews. Part of this was done though an activity in which teachers ranked different models of STEM education by arranging them in a continuum. Findings reveal that teachers are most drawn to models of STEM education that show STEM beyond school settings and that include clear intersections between the disciplines represented in the acronym. This study sheds light on the importance of creating a shared conception of STEM education in order to have productive conversations across various stakeholders within the STEM education community.     

Prospective teachers' initial conceptions about pupils' understanding of science and mathematics

Earlier reports have shown that prospective teachers' conceptions about teaching science to a high degree are resistant and do not change substantially during the teacher‐training programme. In our investigation we elucidate the prospective teachers' initial conceptions about pupils' understanding of science and mathematics. We applied ‘The Lesson Preparation Method' and used a phenomenographic approach in order to reveal the range of conceptions that the prospective teachers hold. A third of the prospective teachers did not consider pupils' conceptions when planning lessons. The rest of the 32 participants expressed awareness; some of the prospective teachers even referred to subject‐specific teaching experience. Also regarding the prospective teachers' conceptions about pupils' knowledge and beliefs, as well as about pupils' difficulties, there was a significant diversity. By raising these issues about pedagogical content knowledge the prospective teachers' conceptions can be extended and developed during the education.     

Improvement Science as a Promising Alternative to Barriers in Improving STEM Teacher Quality through Professional Development

STEM teaching occurs within national and state policy contexts that are constantly shifting in terms of standards and accountability due to the current and intense focus on students’ STEM outcomes. In the last two decades, federal legislation as well as common standards movements increasingly influence what and how STEM teachers instruct their students. Improvement science in education (ISE) has recently emerged as a new method of addressing many of the issues that impact teacher teaching and STEM teacher quality. ISE is a context-focused process improvement approach targeted at school improvement. This article explores three main barriers between STEM teacher professional development and student learning, and focuses on ISE as a promising alternative to current forms of STEM teacher professional development.

Expanding computer science education in schools: understanding teacher experiences and challenges

The increased push for teaching computer science (CS) in schools in the United States requires training a large number of new K-12 teachers. The current efforts to increase the number of CS teachers have predominantly focused on training teachers from other content areas. In order to support these beginning CS teachers, we need to better understand their experiences and challenges encountered in the classroom. This study investigated U.S. CS teachers’ perspectives on the demands of teaching computer science and support needed to ensure quality teaching. Results suggested that teachers face a number of challenges, including isolation, lack of adequate computer science background, and limited professional development resources.     

Implementing curriculum-embedded formative assessment in primary school science classrooms

The implementation of formative assessment strategies is challenging for teachers. We evaluated teachers’ implementation fidelity of a curriculum-embedded formative assessment programme for primary school science education, investigating both material-supported, direct application and subsequent transfer. Furthermore, the relationship between implementation fidelity and teacher variables was explored. N = 17 German primary school teachers participated in professional development on formative assessment, N = 11 teachers formed a control group. Teachers’ implementation fidelity was evaluated via classroom observations student ratings and an analysis of students’ workbooks, focusing on the frequency and quality of intended formative assessment elements (assessments, feedback and instructional adaptations). Regarding direct application, treatment group teachers’ implementation fidelity was high, with slight variations in quality. Regarding transfer, implementation fidelity was lower but teachers still implemented more formative assessment elements than the control group. Teachers’ pedagogical content knowledge and their evaluation of the formative assessment intervention were associated with implementation success.     

The role of non-formal contexts in teacher education for STEM: the case of horno3 science and technology interactive centre

Abstract

Teacher education can benefit directly from experiences in non-formal settings. This article presents a research study with elementary teachers who were teaching in public schools in the state of Nuevo León, México, and participated in a STEM Continuous Professional Development (CPD) workshop. The workshop provided a platform for teachers to interact with scientists and disseminators of science, allowing the appropriation of scientific knowledge applied to everyday activities and settings. Participants improved the quality of their teaching practices in classrooms and gained a new understanding of STEM subjects, enabling them to promote inspiring learning experiences with their students, where dialogue, experimentation and elucidation became an important part of their lessons. The study was carried out using ethnographic tools for analysing recorded videos, 15 sets of field notes, and 49 questionnaires. The sequential analysis of talk and gestures in their participation in the CPD workshop demonstrated high levels of involvement, creativity, and collaborative solution of STEM problems.     

Use of technology-assisted techniques of mind mapping and concept mapping in science education: a constructivist study

The study aims to investigate the effects of using mind maps and concept maps on students' learning of concepts in science courses. A total of 51 students participated in this study which used a quasi-experimental research design with pre-test/post-test control groups. The constructivist-inspired study was carried out in the sixth-grade science course unit of ‘Light and Sound’ in a primary school with two experimental groups and one control group. The intervention was held in the experimental group 1 by using technology-assisted technique of mind mapping, in the experimental group 2 by using technology-assisted technique of concept mapping, and in the control group by means of traditional classroom instruction. After the intervention in the experimental groups, concept tests and open-ended questions related to the unit were used as post-tests. According to the data obtained from concept tests, it was found out that all groups' understanding of concepts was equivalent. Significantly, students in the experimental group 2 reported positive opinions, stating that learning through concept maps was useful and engaging.     

Challenging science teachers' beliefs and practices through a video-case-based intervention in China's primary schools

The present study aims to challenge primary school science teachers' beliefs about education and teaching efficacy, as well as their teaching practices, through a video-case-based intervention programme in a Chinese educational setting. A total of 46 in-service teachers were involved in this study (experimental group = 23, control group = 23). Pre- and post-intervention surveys were administered to examine possible changes in the participants' beliefs about education and science teaching efficacy. Video data were gathered through classroom observations of 9 participants from the experimental group and 9 participants from the control group. The results of one-way analysis of covariance indicate that the reported post-intervention beliefs of teachers who participated in the programme differed significantly from their pre-intervention beliefs. More specifically, teachers in the experimental groups reported fewer traditional and more constructivist beliefs after the intervention, as well as stronger personal science teaching efficacy beliefs. One exception included beliefs about science teaching outcome expectancy. The video data showed that teaching practices became more constructivist in terms of both practical activities and student ICT use.

Preservice elementary teachers' perceptions of their science laboratory instructors in a phenomena-based laboratory and how it impacts their conceptual development

Phenomena-based approaches have become popular for elementary school teachers to engage children's innate curiosity in the natural world. However, integrating such phenomena-based approaches in existing science courses within teacher education programs present potential challenges for both preservice elementary teachers (PSETs) and for laboratory instructors, both of whom may have had limited opportunities to learn or teach science within the student and instructor roles inherent within these approaches. This study uses a convergent parallel mixed-methods approach to investigate PSETs' perceptions of their laboratory instructor's role within a Physical Science phenomena-based laboratory curriculum and how it impacts their conceptual development (2 instructors/121 students). We also examine how the two laboratory instructors' discursive moves within the laboratory align with their's and PSETs' perceptions of the instructor role. Qualitative data includes triangulation between a student questionnaire, an instructor questionnaire, and video classroom observations, while quantitative data includes a nine-item open response pre-/post-semester conceptual test. Guided by Mortimer's and Scott's analytic framework, our findings show that students primarily perceive their instructors as a guide/facilitator or an authoritarian/evaluator. Using Linn's knowledge integration framework, analysis of pre-/post-tests indicates that student outcomes align with students' perceptions of their instructors, with students who perceive their instructor as a guide/facilitator having significantly better pre-/post-outcomes. Additional analysis of scientific discourse from the classroom observations illustrates how one instructor primarily supports PSETs' perspectives on authentic science learning through dialogic–interactive talk moves whereas the other instructor epistemologically stifles personally relevant investigations with authoritative–interactive or authoritative–noninteractive discourse moves. Overall, this study concludes by discussing challenges facing laboratory instructors that need careful consideration for phenomena-based approaches.     

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.
