Teacher Effects on Minority and Disadvantaged Students’ Grade 4 Achievement

ABSTRACT

The authors examined the differential effects of teachers on female, minority, and low-socioeconomic status (SES) students’ achievement in Grade 4. They used data from a randomized experiment (Project STAR) and its follow-up study (LBS). Student outcomes included Grade 4 SAT scores in mathematics, reading, and science and student demographics included gender, race, and SES. The authors used multilevel models to determine how teacher effectiveness interacted with student gender, race, and SES. We also explored whether teacher effects were more pronounced in schools with high proportions of minority or female students. Results indicated that all students benefited from having effective teachers. The differential teacher effects on female, minority, and low-SES students’ achievement, however, were insignificant. There is some evidence in mathematics that teacher effects are more pronounced in high-minority schools. Finally, teacher effects seem to be consistent within and between schools.     

How do Teachers and Textbook Writers Model Scientific Ideas for Students?

Ten experienced science teachers were interviewed about their understandings of the analogical models they use to explain science to their students. The aim was to investigate the notion that teaching pedagogy is influenced by the textbooks commonly used in class. A previously developed typology of analogical models was used to classify each teacher's repertoire of models and the models found in the prescribed science textbooks. The classifications of teacher and textbook models were then compared to identify patterns, similarities and differences. In their interviews, eight of the 10 teachers volunteered that they regularly used models in their lessons. The claimed model use was least for chemistry teachers and highest for physics teachers. Textbook analysis showed that chemistry textbooks used the most models and physics textbooks the least with biology in between. Five teachers saw a need to negotiate with their students the shared and unshared attributes of teaching models and two consistently discussed the limitations of their models. Vignettes and extracts are used throughout the paper to explain how teachers and textbooks use and discuss models.     

Student teachers' conceptions of how to recognise a “Good” primary science teacher: Does two years in a teacher education program make a difference?

Several studies have suggested that preservice teacher education has little impact on student teacher conceptions about various facets of teaching and learning. Most of these studies refer to generic teaching and learning, and very few have related to primary science in particular. To explore this area eight primary student teachers were interviewed on six occasions during the first two years of their Bachelor of Teaching degree. This paper reports the findings from part of these interviews. It describes the (sometimes changing) conceptions which these eight students held about how they would recognise a “good” teacher of science and the people and experiences they believed influenced the formation of these views. The differential impact of past and present teachers and the teacher education program revealed possible implications for practica and science curriculum units in particular, if teacher education is going to have an influence on preservice teachers' conceptions about teaching and learning.     

Addressing Equity and Diversity with Teachers Though Informal Science Institutions and Teacher Professional Development

This study explores how activities developed by science experts in partnership with middle school teachers were employed and interpreted. The goals of this partnership were to (a) help the science teacher meet earth science content standards in new ways, (b) expose students to ‘real world’ experiences outside their school setting, and (c) positively impact teacher practice by providing a program to be used as a catalyst for future learning. Over 300 sixth graders mostly underrepresented science students attended activities at an aquarium serving an urban West Coast urban context. Science teachers, non-science teachers, scientists, and volunteers were all engaged in pre-trip instruction, professional development opportunities, and follow-up activities as this partnership effort explored ways to enhance local literacy initiatives across the curriculum. Results suggest that teacher beliefs about informal education impacted their view and participation in the program and the level of submersion of teachers in collaboration strongly affects the ability to serve underrepresented students on informal excursions. Implications for teacher education and outreach are discussed.     

Understanding aims and values of science: developments in the junior cycle specifications on nature of science and pre-service science teachers’ views in Ireland

Irish science education is aiming to develop post-primary students’ knowledge of and about science through the introduction of ‘nature of science’ (NOS) in the new junior cycle science specification. This study aimed to investigate pre-service science teachers’ views about a particular aspect of NOS, namely the aims and values of science. Aims and values in relation to science can be considered from epistemic, cognitive, cultural, social, political, moral and ethical perspectives. In this paper, we focus on the epistemic, cognitive and social aims and values of science to provide a broad overview and investigate pre-service science teachers’ understanding of them. Qualitative methods are used to highlight two case studies that provide an in-depth record of how pre-service science teachers interpret aims and values of science. Although the sample is limited in terms of its generalisability to pre-service teacher education at large, the study provides a framework for (a) what to target and investigate about NOS in science education, particularly about aims and values of science, and (b) how pre-service science teachers are likely to make sense of such relatively new curricular goals. Implications for pre-service science teacher education are discussed.     

Meta-Representation in an Algebra I Classroom

We describe how 1 Algebra I teacher and her 8th-grade students used meta-representational knowledge when generating and evaluating equations to solve word problems. Analyzing data from a sequence of 4 lessons, we found that the teacher and her students used criteria for evaluating equations, in addition to other types of knowledge (e.g., different interpretations of the equal sign) previously reported in the literature. Moreover, the teacher and her students had trouble understanding one another's proposed algebraic models of problem situations due to differences in the criteria that each applied, and this impeded learning. These findings (a) extend an accumulating body of evidence for the role meta-representation plays in mathematics and science learning and (b) add a new dimension to researchers' growing understanding of what teachers must know in order to teach algebra and other complex mathematics and science topics effectively.     

Positioning participation in the NGSS era: What counts as success?

The Next Generation Science Standards (NGSS) strives to shift science learning from the teacher as a single cognitive agent, to a classroom community in which participants are working together in directing the classroom's communal knowledge to figure out questions about how phenomena occur, and building, testing, and refining their ideas to address those questions. To achieve this type of classroom environment, teachers should attend to students' knowledge and ideas and pay attention to how students are located within teacher-led interactions, such as being positioned as active discussants or designated listeners. In this study, we explore if and how this is occurring in the NGSS era. We used a naturalistic inquiry to explore how an experienced first-grade teacher used a new NGSS-aligned unit that called for students to use the science and engineering practices (SEP) to build content knowledge. We used a macro-analytic lens to answer the research question “how are class discussions shaped to address the SEP”? We used a micro-analytic lens to answer the research question “how are students positioned during these science discussions in this classroom?” Evidence suggests that the teachers' whole class discussions incorporated and involved the SEP which were specified in the unit lessons for content learning. However, on a micro-analytic level, we found that few students were positioned as active discussants. The teacher heavily relied on those students who could provide succinct and clearly relevant answers while positioning the remainder of the students as silent spectators. Implications from this research suggest that not only new NGSS curriculum materials need to focus on what students should know and do but they also need to address heuristics for teachers that show them how to position all of their students as active doers of science so all students have opportunities to build deeper, core science knowledge.     

The pedagogical potential of drawing and writing in a primary science multimodal unit

In consideration of the potential of drawing and writing as assessment and learning tools, we explored how early primary students used these modes to communicate their science understandings. The context for this study was a curricular unit that incorporated multiple modes of representation in both the presentation of information and production of student understanding with a focus on the structure and function of carnivorous plants (CPs). Two science teacher educators and two first-grade teachers in the United States co-planned and co-taught a multimodal science unit on CP structure and function that included multiple representations of Venus flytraps (VFTs): physical specimens, photographs, videos, text, and discussions. Pre- and post-assessment student drawings and writings were statistically compared to note significant changes, and pre- and post-assessment writings were qualitatively analysed to note themes in student ideas. Results indicate that students increased their knowledge of VFT structure and function and synthesised information from multiple modes. While students included more structures of the VFT in their drawings, they were better able to describe the functions of structures in their writings. These results suggest the benefits for student learning and assessment of having early primary students represent their science understandings in multiple modes.     

Student teachers' entry perceptions about teaching primary science: Does a first degree make a difference?

It is problematic whether primary teachers benefit by completing a first degree especially when the teaching of specific subjects, here science, is the focus of attention. This study reports the comparative results of interviewing thirteen Canadian and ten Australian student teachers, both about to commence their Bachelor of Education. The Canadian students had completed an initial degree while nine of the Australian students were school leavers. The interviews, which explored views about teaching primary science, were analysed with this factor in mind. Student teacher perceptions reported include: how to recognise a “good” primary science teacher; perceptions of self as a “good” primary science teacher; expectations of how the teacher education program could assist their science teaching; and whether (for the Canadian students) the initial degree will help in becoming a primary science teacher. Analysis of the interviews suggests possible influences a first degree (among other factors) may have on perceptions related to primary science teaching and raises questions about what is the best general approach for preparing primary teachers to teach science effectivly.     

Curriculum as Experienced by Students: How Teacher Identity Shapes Science Notebook Use

This mixed-methods case study examined the notebook entries of one class of 22 second graders as a way of examining how teacher identity shaped the way students experienced their science curriculum. These notebook entries were created during lessons with three different teachers over the course of one school year, using similar kit-based materials to teach science. The entries were coded for inquiry phase, percent missing or incomplete entries, and driving force (teacher-driven, student-driven, or balanced); chi-squared analyses revealed significant differences among the notebook entries created by the same students during lessons taught by each of the three teachers. Qualitative observations of each teachers' instruction around notebook use supported these quantitative differences, and suggested that the differences in curriculum as experienced by students could be attributed to differences in teacher identity, both who the teacher is and what they do in the classroom. These findings indicate that students' notebooks are useful tools for examining how teachers' identities might shape how elementary students experience science curriculum, and that they can be used to help structure more effective professional development plans for each teacher.     

Understanding the Development of a Hybrid Practice of Inquiry-Based Science Instruction and Language Development: A Case Study of One Teacher’s Journey Through Reflections on Classroom Practice

This qualitative case study looks closely at an elementary teacher who participated in professional development experiences that helped her develop a hybrid practice of using inquiry-based science to teach both science content and English language development (ELD) to her students, many of whom are English language learners (ELLs). This case study examines the teacher’s reflections on her teaching and her students’ learning as she engaged her students in science learning and supported their developing language skills. It explicates the professional learning experiences that supported the development of this hybrid practice. Closely examining the pedagogical practice and reflections of a teacher who is developing an inquiry-based approach to both science learning and language development can provide insights into how teachers come to integrate their professional development experiences with their classroom expertise in order to create a hybrid inquiry-based science ELD practice. This qualitative case study contributes to the emerging scholarship on the development of teacher practice of inquiry-based science instruction as a vehicle for both science instruction and ELD for ELLs. This study demonstrates how an effective teaching practice that supports both the science and language learning of students can develop from ongoing professional learning experiences that are grounded in current perspectives about language development and that immerse teachers in an inquiry-based approach to learning and instruction. Additionally, this case study also underscores the important role that professional learning opportunities can play in supporting teachers in developing a deeper understanding of the affordances that inquiry-based science can provide for language development.     

Construction of meaning in the authentic science writing of deaf students

This study examines how students construct meaning through writing during authentic science activities. To determine how well students understood science concepts, we analyzed 228 writing samples from deaf students in grades 6 through 11 as well as the explanatory and reflective comments of their teachers. The analyses indicate that certain process writing strategies were differentially useful in helping deaf students to construct meaning and in allowing teachers to evaluate the constructed meaning. Three instructional conditions and two teacher variables were found to play roles in determining the accuracy and adequacy of the writing: (1) the writing prompts the teachers used, (2) the focus for the writing, (3) follow-up to the initial writing activity, (4) the teacher's content knowledge, and (5) the teacher's ability to interpret student writing. The authors recommend future applications of writing-to-learn strategies and suggest directions for further research and changes in teacher education.     

Understanding science teaching effectiveness: examining how science-specific and generic instructional practices relate to student achievement in secondary science classrooms

ABSTRACT

In order to create conditions for students’ meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students’ scientific literacy. Better understanding how science teachers’ instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students’ science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers’ value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers’ instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed.     

Ways to prepare future teachers to teach science in multicultural classrooms

Roussel De Carvalho uses the notion of superdiversity to draw attention to some of the pedagogical implications of teaching science in multicultural schools in cosmopolitan cities such as London. De Carvalho makes the case that if superdiverse classrooms exist then Science Initial Teacher Education has a role to play in helping future science teachers to become more knowledgeable and reflective about how to teach school students with a range of worldviews and religious beliefs. The aim of this paper is to take that proposition a step further by considering what the aims and content of a session in teacher education might be. The focus is on helping future teachers develop strategies to teach school students to think critically about the nature of science and what it means to have a scientific worldview. The paper draws on data gathered during an interview study with 28 students at five secondary schools in England. The data was analysed to discover students’ perceptions of science and their perceptions of the way that science responds to big questions about being human. The findings are used to inform a set of three strategies that teachers could use to help young people progress in their understanding of the nature of science. These strategies together with the conceptual framework that underpins them are used to develop a perspective on what kinds of pedagogical content knowledge teacher education might usefully provide.     

Reconceptualised family resemblance approach to nature of science in pre-service science teacher education

A recent framework on nature of science (NOS) is the Family Resemblance Approach (FRA). FRA presents NOS as a cognitive-epistemic and social-institutional system with a set of categories: aims and values, scientific methods, scientific practices, scientific knowledge and social-institutional aspects of science. Although FRA has been problematised philosophically and its implications for science education have been considered by science educators, its empirical adaptations in science education are limited. In order to illustrate the educational adaptations of FRA, we refer to Reconceptualised Family Resemblance Approach to Nature of Science or RFN. We present a study based on a funded pre-service science teacher education project whose aim was to design, implement and evaluate the impact of RFN strategies. Fifteen pre-service teachers participated in a 14-week teacher education intervention that infused RFN. A 70-item questionnaire was designed to investigate the outcomes of the teacher education intervention. Individual interviews with pre-service teachers were also conducted. Quantitative and qualitative data analysis suggest that the teacher education intervention had an overall significant impact on pre-service teachers’ views of NOS. The paper contributes to the understanding of how NOS can be incorporated in science teacher education using a new orientation to NOS based on FRA.     

Coteaching with senior students – a way to refine teachers’ PCK for teaching chemical bonding in upper secondary school

During the last decade there has been on-going discussions about students’ declining interest and low achievement in science. One of the reasons suggested for this decline is that teachers and students have different frames of reference, whereby teachers sometimes communicate science in the classroom in a way that is not accessible to the students. There is a lack of research investigating the effects of coteaching with senior students in science in upper secondary schools. To improve teaching and to narrow the gap between teachers’ and students’ different frames of references, this study investigates how an experienced chemistry teacher gains and refines her pedagogical content knowledge (PCK) by cooperating with two grade 12 students (age 18) as coteachers. The teacher and the two coteachers coplanned, cotaught and coevaluated lessons in chemical bonding in a grade 10 upper secondary class. Findings indicate that the coteachers contributed with their own learning experiences to help the teacher understand how students perceive difficult concepts. In such way, the coteachers were mediating between the teacher and the students, thus bridging the gap between the teacher and the students’ frames of references. The teachers’ PCK was refined which in turn lead to improved teaching strategies.     

Using Automated Scores of Student Essays to Support Teacher Guidance in Classroom Inquiry

Computer scoring of student written essays about an inquiry topic can be used to diagnose student progress both to alert teachers to struggling students and to generate automated guidance. We identify promising ways for teachers to add value to automated guidance to improve student learning. Three teachers from two schools and their 386 students participated. We draw on evidence from student progress, observations of how teachers interact with students, and reactions of teachers. The findings suggest that alerts for teachers prompted rich teacher–student conversations about energy in photosynthesis. In one school, the combination of the automated guidance plus teacher guidance was more effective for student science learning than two rounds of personalized, automated guidance. In the other school, both approaches resulted in equal learning gains. These findings suggest optimal combinations of automated guidance and teacher guidance to support students to revise explanations during inquiry and build integrated understanding of science.     

Elementary teachers’ use of content knowledge to evaluate students’ thinking in the life sciences

Science learning environments should provide opportunities for students to make sense of and enhance their understanding of disciplinary concepts. Teachers can support students’ sense-making by engaging and responding to their ideas through high-leverage instructional practices such as formative assessment (FA). However, past research has shown that teachers may not understand FA, how to implement it, or have sufficient content knowledge to use it effectively. Few studies have investigated how teachers gather information to evaluate students’ ideas or how content knowledge factors into those decisions, particularly within the life science discipline. We designed a study embedded in a multi-year professional development program that supported elementary teachers’ development of disciplinary knowledge and FA practices within science instruction. Study findings illustrate how elementary teachers’ life science content knowledge influences their evaluation of students’ ideas. Teachers with higher levels of life science content knowledge more effectively evaluated students’ ideas than teachers with lower levels of content knowledge. Teachers with higher content exam scores discussed both content and student understanding to a greater extent, and their analyses of students’ ideas were more scientifically accurate compared to teachers with lower scores. These findings contribute to theory and practice around science teacher education, professional development, and curriculum development.
