Science Teacher Attitudes Toward Inquiry-Based Teaching and Learning

The purpose of this study was to determine teachers’ attitudes, values, and beliefs about inquiry. The participants of this study were 275 middle grade and secondary science teachers from four districts in North Carolina. Issues such as class size, accountability, curricular demands, and administrative support are perceived as constraints, impeding the use of inquiry. These are the issues that must be effectively dealt with in the professional education and professional development of all science teachers.     

Effects of Inquiry-Based Teacher Practices on Science Excellence and Equity

Abstract

Within science education reforms, a pedagogical shift from a teacher-centered, textbook-based instructional paradigm to a student-centered, inquiry-based model is called for. Despite strong theoretical grounding, there is limited empirical evidence that these reforms will achieve national goals of academic excellence and equity. The author used hierarchical linear models to estimate the extent to which 5 inquiry-based teacher practices promote achievement of all students (excellence) and reduce gaps in achievement among students with different demographic profiles (equity). Findings suggest that teacher practices that improve overall academic excellence simultaneously are as likely to contribute to greater inequities among more and less advantaged students as they are to close persistent achievement gaps.     

Unpacking the Complex Relationship Between Beliefs,Practice, and Change Related to Inquiry-Based Instruction of One Science Teacher

This case study examines the complex relationship between beliefs, practice, and change related to inquiry-based instruction of one science teacher teaching in a high-poverty urban school. This study explores how video-supported collaboration with peers can provide the catalyst for change. Transcribed collaborative dialogue sessions, written self-reflections, and videotapes of lessons were used to identify and isolate the belief systems that were critical to the teacher’s decision making. The Interconnected Model of Professional Growth was then used to trace the trajectories of change of the individual belief systems. Analysis of the data revealed the relationship between beliefs and practices was complex in which initially espoused beliefs were often inconsistent with enacted practice and some beliefs emerged as more salient than others for influencing practice. Furthermore, this research indicates change in both beliefs and practice was an interactive process mediated by collaborative and self-reflection through participation in the video-supported process.     

Managing Inquiry-Based Science: Challenges in Enacting Complex Science Instruction in Elementary and Middle School Classrooms

Effectively enacting inquiry-based science instruction entails considerable changes in classroom management practices. In this article, we describe five interconnected management areas that need to be addressed when managing an inquiry-oriented K-8 science classroom. We introduce a pyramid model as a framework for thinking about these management areas and present a brief review of what the research literature says about each area. We propose that enacting inquiry-based instruction requires a different kind of approach to classroom management that takes into account the close-knit relationship between management and instruction. This perspective recognizes the pervasive nature of managing the classroom for inquiry learning.

Development and Evaluation of an Inquiry-Based Elementary Science Teacher Education Program Reflecting Current Reform Movements

The National Science Education Standards (National Research Council 1996, National science education standards. Washington, DC: National Academy Press) and various other national and state documents call for teachers who possess science content knowledge, employ an inquiry approach in teaching, and engage in reflective practices. This paper describes a rationale for choosing particular recommendations to implement and how we incorporated those as we revised our elementary science education program. An analysis of the impact of the reformed inquiry-based content courses revealed that students who take more than one reformed content course improve their science content knowledge and efficacy towards teaching science significantly more than students who take fewer courses.     

The Efficacy of Inquiry-Based Instruction in Science: a Comparative Analysis of Six Countries Using PISA 2015

This study is a comparative analysis of 15-year-old students’ scientific literacy, and its association with the instructional strategies that students experience, across six OECD countries that participated in PISA 2015. Across the six countries, the study investigates the efficacy of inquiry-based instruction in science in contrast with two other instructional approaches to teaching secondary science: adaptive and teacher-directed teaching. The analysis shows that students who reported experiencing high frequencies of inquiry strategies in their classrooms consistently evidenced lower levels of scientific literacy across the six countries. Benchmark analysis also showed, common to all six countries, a strongly positive association between the frequency of teacher-directed and adaptive teaching strategies and students’ scientific literacy. Additionally, the study disaggregates PISA’s composite variable representing inquiry-based instruction and shows that different components of inquiry are differentially associated with students’ scientific literacy. We discuss the implications of these analyses for science teacher educators, science teachers, and educational policy makers. In doing so, we add nuance to our understanding of the efficacy of inquiry-based instruction in science, suggesting that some components, as conceptualised and assessed in PISA, seem to suggest greater attention and use, and others more moderated use.

     

Teaching Neuroscience to Science Teachers: Facilitating the Translation of Inquiry-Based Teaching Instruction to the Classroom

In science education, inquiry-based approaches to teaching and learning provide a framework for students to building critical-thinking and problem-solving skills. Teacher professional development has been an ongoing focus for promoting such educational reforms. However, despite a strong consensus regarding best practices for professional development, relatively little systematic research has documented classroom changes consequent to these experiences. This paper reports on the impact of sustained, multiyear professional development in a program that combined neuroscience content and knowledge of the neurobiology of learning with inquiry-based pedagogy on teachers’ inquiry-based practices. Classroom observations demonstrated the value of multiyear professional development in solidifying adoption of inquiry-based practices and cultivating progressive yearly growth in the cognitive environment of impacted classrooms.Current discussion about educational reform among business leaders, politicians, and educators revolves around the idea students need “21st century skills” to be successful today (Rotherham and Willingham, 2009 ). Proponents argue that to be prepared for college and to be competitive in the 21st-century workplace, students need to be able to identify issues, acquire and use new information, understand complex systems, use technologies, and apply critical and creative thinking skills (US Department of Labor, 1991 ; Bybee et al., 2007 ; Conley, 2007 ). Advocates of 21st-century skills favor student-centered methods—for example, problem-based learning and project-based learning. In science education, inquiry-based approaches to teaching and learning provide one framework for students to build these critical-thinking and problem-solving skills (American Association for the Advancement of Science [AAAS], 1993 ; National Research Council [NRC], 2000 ; Capps et al., 2012 ).Unfortunately, in spite of the central role of inquiry in the national and state science standards, inquiry-based instruction is rarely implemented in secondary classrooms (Weiss et al., 1994 ; Bybee, 1997 ; Hudson et al., 2002 ; Smith et al., 2002 ; Capps et al., 2012 ). Guiding a classroom through planning, executing, analyzing, and evaluating open-ended investigations requires teachers to have sufficient expertise, content knowledge, and self-confidence to be able to maneuver through multiple potential roadblocks. Researchers cite myriad reasons for the lack of widespread inquiry-based instruction in schools: traditional beliefs about teaching and learning (Roehrig and Luft, 2004 ; Saad and BouJaoude, 2012 ), lack of pedagogical skills (Shulman, 1986 ; Adams and Krockover, 1997 ; Crawford, 2007 ), lack of time (Loughran, 1994 ), inadequate knowledge of the practice of science (Duschl, 1987 ; DeBoer, 2004 ; Saad and BouJaoude, 2012 ), perceived time constraints due to high-stakes testing, and inadequate preparation in science (Krajcik et al., 2000 ). Yet teachers are necessarily at the center of reform, as they make instructional and pedagogical decisions within their own classrooms (Cuban, 1990 ). Given that effectiveness of teachers’ classroom practices is critical to the success of current science education reforms, teacher professional development has been an ongoing focus for promoting educational reform (Corcoran, 1995 ; Corcoran et al., 1998 ).A review of the education research literature yields an extensive knowledge base in “best practices” for professional development (Corcoran, 1995 ; NRC, 1996 ; Loucks-Horsley and Matsumoto, 1999 ; Loucks-Horsley et al., 2009 ; Haslam and Fabiano, 2001 ; Wei et al., 2010 ). However, in spite of a strong consensus on what constitutes best practices for professional development (Desimone, 2009 ; Wei et al., 2010 ), relatively little systematic research has been conducted to support this consensus (Garet et al., 2001 ). Similarly, when specifically considering the science education literature, several studies have been published on the impact of teacher professional development on inquiry-based practices (e.g., Supovitz and Turner, 2000 ; Banilower et al., 2007 ; Capps et al., 2012 ). Unfortunately, these studies usually rely on teacher self-report data; few studies have reported empirical evidence of what actually occurs in the classroom following a professional development experience.Thus, in this study, we set out to determine through observational empirical data whether documented effective professional development does indeed change classroom practices. In this paper, we describe an extensive professional development experience for middle school biology teachers designed to develop teachers’ neuroscience content knowledge and inquiry-based pedagogical practices. We investigate the impact of professional development delivered collaboratively by experts in science and pedagogy on promoting inquiry-based instruction and an investigative classroom culture. The study was guided by the following research questions:

1. Were teachers able to increase their neuroscience content knowledge?
2. Were teachers able to effectively implement student-centered reform or inquiry-based pedagogy?
3. Would multiple years of professional development result in greater changes in teacher practices?

Current reforms in science education require fundamental changes in how students are taught science. For most teachers, this requires rethinking their own practices and developing new roles both for themselves as teachers and for their students (Darling-Hammond and McLaughlin, 1995 ). Many teachers learned to teach using a model of teaching and learning that focuses heavily on memorizing facts (Porter and Brophy, 1988 ; Cohen et al., 1993 ; Darling-Hammond and McLaughlin, 1995 ), and this traditional and didactic model of instruction still dominates instruction in U.S. classrooms. A recent national observation study found that only 14% of science lessons were of high quality, providing students an opportunity to learn important science concepts (Banilower et al., 2006 ). Shifting to an inquiry-based approach to teaching places more emphasis on conceptual understanding of subject matter, as well as an emphasis on the process of establishing and validating scientific concepts and claims (Anderson, 1989 ; Borko and Putnam, 1996 ). In effect, professional development must provide opportunities for teachers to reflect critically on their practices and to fashion new knowledge and beliefs about content, pedagogy, and learners (Darling-Hammond and McLaughlin, 1995 ; Wei et al., 2010 ). If teachers are uncomfortable with a subject or believe they cannot teach science, they may focus less time on it and impart negative feelings about the subject to their students. In this way, content knowledge influences teachers’ beliefs about teaching and personal self-efficacy (Gresham, 2008 ). Personal self-efficacy was first defined as “the conviction that one can successfully execute the behavior required to produce the outcomes” (Bandura, 1977 , p.193). Researchers have reported self-efficacy to be strongly correlated with teachers’ ability to implement reform-based practices (Mesquita and Drake, 1994 ; Marshall et al., 2009 ).Inquiry is “a multifaceted activity that involves making observations, posing questions, examining books and other sources of information, planning investigations, reviewing what is already known in light of evidence, using tools to gather, analyze and interpret data, proposing answers, explanations and predictions, and communicating the results” (NRC, 1996 , p. 23). Unfortunately, most preservice teachers rarely experience inquiry-based instruction in their undergraduate science courses. Instead, they listen to lectures on science and participate in laboratory exercises with guidelines for finding the expected answer (Gess-Newsome and Lederman, 1993 ; DeHaan, 2005 ). As such, teachers’ knowledge and beliefs about teaching and learning were developed over the many years of their own educations, through “apprenticeship of observation” (Lortie, 1975 ), in traditional lecture-based settings that they then replicate in their own classrooms. To support the implementation of inquiry in K–12 classrooms, teachers need firsthand experiences of inquiry, questioning, and experimentation within professional development programs (Gess-Newsome, 1999 ; Supovitz and Turner, 2000 ; Capps et al., 2012 ).A common criticism of professional development activities is that they are too often one-shot workshops with limited follow-up after the workshop activities (Darling-Hammond, 2005 ; Wei et al., 2010 ). The literature on teacher learning and professional development calls for professional development that is sustained over time, as the duration of professional development is related to the depth of teacher change (Shields et al., 1998 ; Weiss et al., 1998 ; Supovitz and Turner, 2000 ; Banilower et al., 2007 ). If the professional development program is too short in duration, teachers may dismiss the suggested practices or at best assimilate teaching strategies into their current repertoire with little substantive change (Tyack and Cuban, 1995 ; Coburn, 2004 ). For example, Supovitz and Turner (2000 ) found that sustained professional development (more than 80 h) was needed to create an investigative classroom culture in science, as opposed to small-scale changes in practices. Teachers need professional development that is interactive with their teaching practices; in other words, professional development programs should allow time for teachers to try out new practices, to obtain feedback on their teaching, and to reflect on these new practices. Not only is duration (total number of hours) of professional development important, but also the time span of the professional development experience (number of years across which professional hours are situated) to allow for multiple cycles of presentation and reflection on practices (Blumenfeld et al., 1991 ; Garet et al., 2001 ). Supovitz and Turner''s study (2000) suggests that it is more difficult to change classroom culture than teaching practices; the greatest changes in teaching practices occurred after 80 h of professional development, while changes in classroom investigative culture did not occur until after 160 h of professional development.Finally, research indicates that professional development that focuses on science content and how children learn is important in changing teaching practices (e.g., Corcoran, 1995 ; Desimone, 2009 ), particularly when the goal is the implementation of inquiry-like instruction designed to improve students’ conceptual understanding (Fennema et al., 1996 ; Cohen and Hill, 1998 ). The science content chosen for the professional development series described in this study was neuroscience. This content is relevant for both middle and high school science teachers and has direct connections to standards. It also is unique in that it encompasses material on the neurological basis for learning, thus allowing discussions about student learning to occur within both a scientific and pedagogical context. As a final note, it is rare for even a life science teacher to have taken any coursework in neuroscience. The inquiry-based lessons and experiments encountered by the teachers during the professional development provide an authentic learning experience, allowing teachers to truly inhabit the role of a learner in an inquiry-based setting.     

Effective,Sustained Inquiry-Based Instruction Promotes Higher Science Proficiency Among All Groups: A 5-Year Analysis

Student’s performance in science classrooms has continued to languish throughout the USA. Even though proficiency rates on national tests such as National Assessment of Educational Progress are higher for Caucasian students than African-Americans and Hispanics, all groups lack achieving desired proficiency rates. Further, the Next Generation Science Standards detail a new higher benchmark for all students. This study analyzes a professional development (PD) project, entitled Inquiry in Motion, designed to (a) facilitate teacher transformation toward greater quantity and quality of inquiry-based instruction, (b) improve student achievement in science practices and science concepts, and (c) begin to narrow the achievement gap among various groups. This 5-year PD study included 11 schools, 74 middle school teachers, and 9,981 students from diverse, high minority populations. Findings from the quasi-experimental study show statistically significant gains for all student groups (aggregate, males, females, Caucasians, African-Americans, and Hispanics) on all three science Measure of Academic Progress tests (composite, science practices, and science concepts) when compared to students of non-participating teachers. In addition to an increase in overall performance for all groups, a narrowing of the achievement gap of minority students relative to Caucasian students was seen. When combined with other studies, this study affirms that, when facilitated effectively, inquiry-based instruction may benefit all students, for all demographic groups measured.     

Multifaceted Assessment of Inquiry-Based Science Learning

To improve student science achievement in the United States we need inquiry-based instruction that promotes coherent understanding and assessments that are aligned with the instruction. Instead, current textbooks often offer fragmented ideas and most assessments only tap recall of details. In this study we implemented 10 inquiry-based science units that promote knowledge integration and developed assessments that measure student knowledge integration abilities. To measure student learning outcomes, we designed a science assessment consisting of both proximal items that are related to the units and distal items that are published from standardized tests (e.g., Trends in International Mathematics and Science Study). We compared the psychometric properties and instructional sensitivity of the proximal and distal items. To unveil the context of learning, we examined how student, class, and teacher characteristics affect student inquiry science learning. Several teacher-level characteristics including professional development showed a positive impact on science performance.

Inquiry-Based Early Childhood Teacher Preparation: The Personal Learning Plan Method

The purpose of this paper is to describe a Personal Learning Plan method used in undergraduate early childhood education courses as a specific case of learner-centered, inquiry-based instruction. A rationale for this approach to instruction, the instructional context in which the specific method was developed and used, the method framework (i.e., preliminary and final plans, activities, products, and reflections), and the evaluation process will be discussed. Finally, a discussion of the perceived benefits and challenges of the method as it has been implemented will be presented.     

Organizing for Teacher Agency in Curricular Co-Design

Cultural-historical activity theory (CHAT) approaches to intervention aim for transformative agency, that is, collective actions that expand and bring about new possibilities for activity. In this article, we draw on CHAT as a resource for organizing design research that promotes teachers’ agency in designing new science curriculum materials. We describe how CHAT informed our efforts to structure a collaborative design space in which teachers and other participants sought to develop new curriculum materials intended to help realize a new vision for science education. Specifically, we describe the tools and routines we deployed to support the design process, and we analyze the ways in which teachers took up elements of our design process as well as how they adapted, resisted, and suggested alternative tools and strategies to help develop new curriculum materials. In so doing, we illustrate ways in which CHAT can serve as a guide both for organizing collaborative design processes and for analyzing their efficacy.     

Elementary Preservice Teachers' Struggles to Define Inquiry-Based Science Teaching

Our Practice, Their Readiness: Teacher Educators Collaborate to Explore and Improve Preservice Teacher Readiness for Science and Math Instruction

Since many preservice teachers (PTs) display anxiety over teaching math and science, four PT educators collaborated to better understand the PTs’ background experiences and attitudes toward those subjects. The research project provided two avenues for professional learning: the data collected from the PTs and the opportunity for collaborative action research. The mixed method study focused on: the relationship between gender and undergraduate major (science versus non-science) with respect to previous and current engagement in science and math, understanding the processes of inquiry, and learning outside the classroom. A field trip to a science center provided the setting for the data collection. From a sample of 132 PTs, a multivariate analysis showed that the science major of PTs explained most of the gender differences with respect to the PTs’ attitudes toward science and mathematics. The process of inquiry is generally poorly interpreted by PTs, and non-science majors prefer a more social approach in their learning to teach science and math. The four educators/collaborators reflect on the impacts of the research on their individual practices, for example, the need to: include place-based learning, attend to the different learning strategies taken by non-science majors, emphasize social and environmental contexts for learning science and math, be more explicit regarding the processes of science inquiry, and provide out-of-classroom experiences for PTs. They conclude that the collaboration, though difficult at times, provided powerful opportunities for examining individual praxis.     

Risk in Science Instruction

Risk is always present in people’s lives: diseases, new technologies, socio-scientific issues (SSIs) such as climate change, and advances in medicine—to name just a few examples—all carry risks. To be able to navigate risks in everyday life, as well as to participate in social debate on risk-related issues, students need to develop risk competence. Science education can be a powerful tool in supporting students’ risk competence, which is an important component of scientific literacy. As there are different definitions of risk within the scientific community, the aims of this article are (1) to review the literature on two major theoretical frameworks for conceptualising risk, the realist, and the constructivist paradigms of risk and (2) to connect both in order to suggest a working definition of what can be understood as risk competence in science instruction.     

Inquiry-Based Science: Turning Teachable Moments into Learnable Moments

This study examines how an inquiry-based approach to teaching and learning creates teachable moments that can foster conceptual understanding in students, and how teachers capitalize upon these moments. Six elementary school teachers were videotaped as they implemented an integrated inquiry-based science and literacy curriculum in their classrooms. In this curriculum, science inquiry implies that students search for evidence in order to make and revise explanations based on the evidence found and through critical and logical thinking. Furthermore, the curriculum material is designed to address science key concepts multiple times through multiple modalities (do it, say it, read it, write it). Two types of teachable moments were identified: planned and spontaneous. Results suggest that the consolidation phases of inquiry, when students reinforce new knowledge and connect their empirical findings to theory, can be considered as planned teachable moments. These are phases of inquiry during which the teacher should expect, and be prepared for, student utterances that create opportunities to further student learning. Spontaneous teachable moments are instances when the teacher must choose to either follow the pace of the curriculum or adapt to the students’ need. One implication of the study is that more teacher support is required in terms of how to plan for and effectively utilize the consolidation phases of inquiry.
