Prospective elementary teachers' prior knowledge about light

This article reports on a study that was designed to describe prospective elementary teachers' prior verbal and diagrammatic knowledge about various aspects of light, seeing, shadows, and mirror images. Data were collected through individual interviews using simple apparatus (light bulb, objects, screen, and plane mirror). Included are some inferences about how students' ideas may have emerged from their interpretations of everyday experiences. The article concludes with a section that provides an example of a conceptual change instructional strategy that was based on the research results reported here.     

Preservice elementary teachers' conceptions of moon phases before and after instruction

This study focused on the conceptual understandings held by 78 preservice elementary teachers about moon phases, before and after instruction. Participants in the physics groups received instruction on moon phases in an inquiry‐based physics course; participants in the methods group received no instruction on moon phases. The instructive effect of two different types of preinstruction interviews also was compared. The instruction on moon phases used in the study is from Physics by Inquiry by Lillian McDermott. In the study, the method of inquiry followed a qualitative design, involving classroom observations, document analysis, and structured interviews. Inductive data analysis identified patterns and themes in the participants' conceptual understanding. Results indicate that without the instruction, most preservice teachers were likely to hold alternative conceptions on the cause of moon phases. Participants who had the instruction were much more likely to hold a scientific understanding after instruction. The instruction appears to be more effective in promoting a scientific understanding of moon phases than instruction previously reported in the literature. It also appears that using a three‐dimensional model or making two‐dimensional drawings during the preinstruction interviews does not have instructive value. © 2002 Wiley Periodicals, Inc.

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.     

Evaluating prospective elementary teachers' understanding of science and mathematics in a model preservice program

Two cohorts of students preparing to become elementary teachers participated in a model program in science and mathematics. These students were compared to other students taking similar courses on their conceptual understandings of science and mathematics, their investigative proficiencies, and their beliefs about effective methods of teaching these subjects. Instruments included newly developed tests of understanding, existing standardized achievement tests, and instruments devised for the evaluation to elicit conceptions of appropriate ways to teach science and mathematics to elementary children. Results from individual courses indicated that students participating in the model program developed more thorough understandings and more reform-minded beliefs related to teaching science and mathematics. Issues associated with the assessment and evaluation of innovative programs in science and mathematics are discussed, and recommendations for teacher preparation are offered.     

Combined fluency and cognitive strategies instruction improves mathematics achievement in early elementary school

One hundred and seventy-eight second grade students from two states (Georgia and Massachusetts) participated in an experiment in which they were randomly assigned to either (1) a computer program designed to increase fluency in addition and subtraction, (2) a program designed to improve cognitive strategy use for addition and subtraction, (3) a program that combined the fluency and cognitive strategy instruction programs or (4) a control condition. The intervention consisted of 40 half-hour sessions (2 sessions per week for 20 weeks). Prior to the intervention, and immediately following the intervention, the participants were tested on fluency, cognitive strategy use, and mathematics achievement. ANCOVAs indicated that children in the combined fluency and cognitive strategy use condition significantly improved their mathematics achievement in comparison to the control group. When we examined the impact of the intervention as a function of gender, boys appeared to benefit from the intervention, but girls did not.     

Impacts of contextual and explicit instruction on preservice elementary teachers' understandings of the nature of science

This mixed‐methods investigation compared the relative impacts of instructional approach and context of nature of science instruction on preservice elementary teachers' understandings. The sample consisted of 75 preservice teachers enrolled in four sections of an elementary science methods course. Independent variables included instructional approach to teaching nature of science (implicit vs. explicit) and the context of nature of science instruction (as a stand‐alone topic vs. situated within instruction about global climate change and global warming). These treatments were randomly applied to the four class sections along a 2 × 2 matrix, permitting the comparison of outcomes for each independent variable separately and in combination to those of a control group. Data collection spanned the semester‐long course and included written responses to pre‐ and post‐treatment administrations of the VNOS‐B, semi‐structured interviews, and a variety of classroom artifacts. Qualitative methods were used to analyze the data with the goal of constructing profiles of participants' understandings of the nature of science and of global climate change /global warming (GCC/GW). These profiles were compared across treatments using non‐parametric statistics to assess the relative effectiveness of the four instructional approaches. Results indicated that preservice teachers who experienced explicit instruction about the nature of science made statistically significant gains in their views of nature of science regardless of whether the nature of science instruction was situated within the context of GCC/GW or as a stand‐alone topic. Further, the participants who experienced explicit nature of science instruction as a stand‐alone topic were able to apply their understandings of nature of science appropriately to novel situations and issues. We address the implications of these results for teaching the nature of science in teacher preparation courses. © 2010 Wiley Periodicals, Inc., Inc. J Res Sci Teach 48: 414–436, 2011     

Reading comprehension instruction in Irish primary classrooms: key insights into teachers' perspectives on classroom practices

Despite a wealth of international research indicating the importance but also the dearth of explicit reading comprehension instruction in classrooms, current classroom reading pedagogy does not appear to have acknowledged and addressed this shortcoming to any significant degree. This is cause for some considerable concern, as today's students require effective, metacognitive reading comprehension strategies in order to succeed in a vastly expanding multi-literate textual environment. This paper will discuss a recent study, involving a survey (n=278) and interviews (n=12), which examined current beliefs and understandings regarding reading, as well as reading pedagogy and practice among teachers at primary level in Ireland. The findings revealed that current reading pedagogy, as indicated by the surveyed teachers, relies heavily on decoding instruction and an affective approach to reading while explicit comprehension instruction practice remains secondary and more the exception rather than the rule. The paper will attempt to examine possible reasons as to why current reading pedagogy remains ‘un-balanced’ in this manner while also exploring possible avenues for improvement.     

Flipping instruction in a fifth grade class: A case of an elementary mathematics specialist

Flipped instruction, in which information typically conveyed through in-class lectures is delivered remotely through video or text, is being used increasingly by teachers at all levels. However, there is little research documenting how elementary teachers think about, plan for, and use flipped instruction. In this article, we use data from interviews, class observations, and an analysis of instructional videos to describe an elementary mathematics specialists' efforts to incorporate flipped instruction for mathematics in her fifth grade class. We use this case to highlight how a knowledgeable teacher might use flipped instruction to enhance her teaching, and also describe potential challenges.     

Supporting mathematics vocabulary instruction through mathematics curricula

Abstract

This study examines four of the most commonly-used core mathematics curricula in the USA for evidence of support for research-based instructional strategies for mathematics vocabulary in first and second grade. Content analyses of the teachers’ editions of two units for each grade level were analyzed per curriculum (n?=?16). Statistically significant differences among curricula were found for number of target words (range 6–51 per unit), level of difficulty of terms (basic to technical), and number of support strategies per word. Multiple means of representation varied in terms of verbal and non-verbal strategies for target terms. These differences indicate children are experiencing substantially different mathematics vocabulary learning opportunities, which may impact later mathematics achievement. Implications for practice, curriculum development, and future research are addressed.     

The challenge of altering elementary school teachers' beliefs and practices regarding linguistic and cultural diversity in science instruction

This study examined the impact of a professional development intervention aimed at helping elementary teachers incorporate elements of students' home language and culture into science instruction. The intervention consisted of instructional units and materials and teacher workshops. The research involved 43 third‐ and fourth‐grade teachers at six elementary schools in a large urban school district. These teachers participated in the intervention for 2 consecutive years. The study was conducted using both quantitative and qualitative methods based on focus group interviews, a questionnaire, and classroom observations. The results indicate that as teachers began their participation in the intervention, they rarely incorporated students' home language or culture into science instruction. During the 2‐year period of the intervention, teachers' beliefs and practices remained relatively stable and did not show significant change. Possible explanations for the limited effectiveness of the intervention are addressed, and implications for professional development efforts are discussed. © 2007 Wiley Periodicals, Inc.

Journal writing and mathematics instruction

In this article we discuss the educational value of engaging mathematics students in a specific form of writing to learn—the keeping of a journal throughout a mathematics course. As the result of an analysis which comprises both conceptual and empirical components, we suggest that journals have the potential to contribute to mathematics instruction in several ways. As the students write the journals, they can be encouraged to express and reflect upon their feelings, knowledge, processes and beliefs about mathematics, and consequently grow along each of these dimensions. By reading their students' journals, teachers may receive a wealth of information about their students and the course, and consequently improve their teaching. Finally, journals can create a new form of dialogue between the teacher and each student, thus allowing for more individualized instruction and a supportive classroom atmosphere.     

On the nature of teaching nature of science: Preservice early childhood teachers' instruction in preschool and elementary settings

This study explored whether early childhood preservice teachers' concerns about teaching nature of science (NOS) and their intellectual levels influenced whether and how they taught NOS at the preschool and primary (K‐3) levels. We used videotaped classroom observations and lesson plans to determine the science instructional practices at the preschool and primary levels, and to track whether and how preservice teachers emphasized NOS. We used the Stages of Concern Questionnaire (SOCQ) pre‐ and postinternship to determine concerns about NOS instruction, and the Learning Context Questionnaire (LCQ) to determine intellectual levels. We found that neither concerns about teaching NOS nor intellectual level were related to whether and how the preservice teachers emphasized NOS; however, we found that all preservice early childhood teachers began their internships with NOS concern profiles of “worried.” Two preservice teachers' NOS concerns profiles changed as a result of their internships; one to “cooperator” and one to “cooperator/improver.” These two preservice teachers had cooperating teachers who were aware of NOS and implemented it in their own science instruction. The main factors that hindered or facilitated teaching NOS for these preservice teachers were the influence of the cooperating teacher and the use of the science curriculum. The preservice teacher with the cooperating teacher who understood and emphasized NOS herself and showed her how to modify the curriculum to include NOS, was able to explicitly teach NOS to her students. Those in classrooms whose cooperating teachers did not provide support for NOS instruction were unable to emphasize NOS. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 47:213–233, 2010     

Prospective teachers' metaphorical conceptualizations of learner

This study investigated the metaphorical images that prospective teachers in Turkey formulated to describe learners. Participants (N = 2847) completed the prompt “A student is like … because …” to indicate their conceptualizations of learner. Data were analyzed both qualitatively and quantitatively. Altogether 98 well-articulated metaphorical images were identified and 12 conceptual themes were developed. Significant associations were detected between teacher trainees' gender, programme type and status in programme, and the 12 conceptual themes. Metaphors provided a cognitive lens into prospective teachers' thinking and cognition. Implications for teacher education and further research are discussed.     

Effects of metacognitive strategy instruction and instruction time on reading comprehension

Ten-year-old students in an experimental group and a control group were tested for metacognitive abilities in reading comprehension before and after implementation of treatment in the experimental group. The teachers of the students in the experimental group were trained in metacognitive strategy instruction and in optimizing instruction time for reading comprehension. The learning gains made by the students in the experimental group in metacognitive abilities for reading comprehension turned out to be significantly greater than those made by the students in the control group. In the next school, year the students in the former experimental group and the former control group were tested for reading comprehension. It turned out that the students in the former experimental group had significantly better results on reading comprehension than the students in the former control group.
