Connecting Classroom Science with Everyday Life: Teachers’ Attempts and Students’ Insights

This multiple case study examines how teachers request students’ use of their content knowledge and conceptual understandings from out-of-school experiences while reasoning about science concepts and the ways in which students perceive and respond to these requests. Three middle school teachers and a total of 57 middle school students participated in this study. The data collection involved classroom observations and multiple interviews with each of the teachers individually and with small groups of students. The findings indicate that the students appreciate the usefulness of making relevant connections between their in-school and out-of-school learning, but seldom do so during science lessons. We also found that teachers’ attempts to facilitate these types of connections during classroom discourse events involved the use of analogies, examples, or questions. Finally, the findings also indicate that students often recognize teachers’ requests but seldom relate to these requests in the way the teacher intends.     

Opportunity-to-learn performance levels and student achievement gains for students with and without disabilities

This study examined within-year mathematics gains in the context of students’ education status and teachers’ opportunity-to-learn (OTL) performance for 60 general education teachers and 219 students with and without disabilities. Multilevel analyses did not support teachers’ OTL performance as a statistically significant predictor of model slope or intercept. Effect sizes for the Level-2 intercept variance suggested that OTL performance has some utility in explaining variations in mean initial achievement level between teachers. Contingency tables for a subsample of teachers indicated that higher OTL performance resulted in greater achievement gain irrespective of education status with greater gain for students with disabilities.     

A longitudinal study of children's early literacy experiences at home and later literacy development at home and school

Studies of literacy attainment in the early years of school have identified various measures at school entry which predict later attainment. The study reported has sought not only to replicate earlier findings but to investigate significant home factors from a younger age. Literacy experiences of 42 children at ages 3, 5 and 7 were investigated, and the relationship of home factors to literacy development explored. Findings are reported concerning two outcome measures at age 7: children's reading level, as determined by the difficulty level of their school reading book, and whether or not children at age 7 were judged to have literacy difficulties. Significant factors included having favourite books at age 3; letter knowledge and parents reading to children at school entry; and at age 7, access to home computers, and parents’ knowledge of literacy teaching in school. Children with literacy difficulties owned fewer books, were less likely to read to themselves or their parents, and generally had less support for literacy at home. Implications for teachers, highlighting the relevance of home literacy, are discussed. The findings underline the importance of home factors for children's literacy development.     

The pedagogy of argumentation in science education: science teachers’ instructional practices

ABSTRACT

Argumentation has been a prominent concern in science education research and a common goal in science curriculum in many countries over the past decade. With reference to this goal, policy documents burden responsibilities on science teachers, such as involving students in dialogues and being guides in students’ spoken or written argumentation. Consequently, teachers’ pedagogical practices regarding argumentation gain importance due to their impact on how they incorporate this practice into their classrooms. In this study, therefore, we investigated the instructional strategies adopted by science teachers for their argumentation-based science teaching. Participants were one elementary science teacher, two chemistry teachers, and four graduate students, who have a background in science education. The study took place during a graduate course, which was aimed at developing science teachers’ theory and pedagogy of argumentation. Data sources included the participants’ video-recorded classroom practices, audio-recorded reflections, post-interviews, and participants’ written materials. The findings revealed three typologies of instructional strategies towards argumentation. They are named as Basic Instructional Strategies for Argumentation, Meta-level Instructional ?St??rategies for ?Argumentation, and Meta-strategic Instructional ?St??rategies for ?Argumentation. In conclusion, the study provided a detailed coding framework for the exploration of science teachers’ instructional practices while they are implementing argumentation-based lessons.     

Country,School and Students Factors Associated with Extreme Levels of Science Literacy Across 25 Countries

A huge gap in science literacy is between students who do not show the competencies that are necessary to participate effectively in life situations related to science and technology and students who have the skills which would give them the potential to create new technology. The objective of this paper is to identify, for 25 countries, distinct subgroups of students with characteristics that appear to be associated with this proficiency gap. Data were based on the answers of 46,131 PISA 2006 students with scores classified below level 2 or above level 4, as well as the answers of their principals to school questionnaire and the OECD indicators of the financial and human resources invested in education at the national level for secondary school. The dependent variable of the analysis was a dichotomous variable the values of which represent the two different groups of students. The independent variables were the OECD indicators, and the items and indices derived from the student and school questionnaires. The analysis was based on classification trees and the findings were replicated and extended by the means of a multilevel logistic regression model. The results show that very specific levels of teachers’ salaries, parental pressure on schools, school size, awareness of environmental issues, science self-efficacy and socio-economic status have a very important role in predicting whether 15 year olds in OECD countries will belong to the lower or the highest proficiency groups as regards their aptitude in the context of life situations involving problems of a scientific nature.     

The Common Core State Standards and Reading: Interpretations and Implications for Elementary Students with Learning Disabilities

The K‐5 reading standards within the English Language Arts Common Core State Standards provide guidance to teachers about grade level expectations for students. Though the authors of the standards acknowledge that some students may experience difficulty reaching the rigorous expectations, they explain that the standards outline a pathway to proficiency for all students, including those who struggle with literacy. Students with learning disabilities, who often have significant literacy difficulties, may face particular challenges when their instruction is framed by these standards. This article unpacks the complex K‐5 reading standards and provides a discussion of the implications for students with learning disabilities and their general and special education teachers. Examples from K‐5 lessons and recommendations for teachers and researchers are provided.

Teaching primary science: emotions, identity and the use of practical activities

This paper uses cultural historical activity theory to examine the interactions between the choices primary teachers make in the use of practical activities in their teaching of science and the purposes they attribute to these; their emotions, background and beliefs; and the construction of their identities as teachers of science. It draws on four case studies of science lessons taught over a term by four exemplary teachers of primary science. The data collected includes video recordings of science lessons, interviews with each teacher and some of their students, student work, teachers?? planning documents and observation notes. In this paper, we examine the reflexive relationship between emotion and identity, and the teachers?? objectives for their students?? learning; the purposes (scientific and social) the teachers attributed to practical activities; and the ways in which the teachers incorporated practical activities into their lessons. The findings suggest that it is not enough to address content knowledge, pedagogy and pedagogical content knowledge in teacher education, but that efforts also need to be made to influence prospective primary teachers?? identities as scientific thinkers and their emotional commitment to their students?? learning of science.     

Determinants of literacy proficiency: a lifelong-lifewide learning perspective

The aim of this article is to investigate the predictive capacity of major determinants of literacy proficiency that are associated with a variety of contexts including school, home, work, community and leisure. An identical structural model based on previous research is fitted to data for 18 countries. The results show that even after accounting for all factors education remains the most important predictor of literacy proficiency. In all countries, however, the total effect of education is significantly mediated through further learning occurring at work, at home and in the community. Therefore, the job and other literacy-related factors complement education in predicting literacy proficiency. This result points to a virtual cycle of lifelong learning, particularly to how educational attainment influences other learning behaviours throughout life. In addition, results show that home background as measured by parents’ education is also a strong predictor of literacy proficiency, but in many countries this occurs only if a favourable home background is complemented by some post-secondary education.     

INSTRUCTIONAL ACTIVITIES AND GROUP WORK IN THE US INCLUSIVE HIGH SCHOOL CO-TAUGHT SCIENCE CLASS

In the US, there is a significant number of learning-disabled high school students included in regular science classrooms. It has been argued that students with learning disabilities can succeed in science if they receive the kind of instruction they need. To facilitate such instruction, the special education teacher is often incorporated into the class along with the learning disabled students. We observed 53 high school science lessons from ten pairs of science and special-education teachers who were responsible for delivering instruction to groups of students, some of whom were learning-disabled. We analyzed narrative notes collected in these lessons reflecting the kinds of classroom activities, organization of work, and teachers’ roles. In addition, we interviewed the teachers individually to gain a better understanding of these inclusive classes. The underlying question of this research was whether inclusive classes with two teachers delivered the type of science education that is better than solo-teaching in addressing the needs of learning-disabled students. Our evidence indicates that even with a special-education teacher present in the class, learning-disabled students usually did not receive a science education that met their needs. We elaborate on the reasons for this problem and make suggestions for improvement.     

A comparison of elementary teacher attitudes and skills in teaching science in Australia and the United States

A study, originally don in Australia in 1983, was replicated in an urban-suburb in the Unitd States. The Australian project vivolved matched pairs of year-fiv teachers in one of two workshops. One workshop taught the skills of teaching electricity, while the other one discussed issues in gender equity in science education (active participation of both girls and boys, comparble student-teacher interactions, and research findings concerning equity). The U.S. study provided three types of workshops (skills, equity and skills, and equity) for comparable groups of fourth and fifth grade teachers. All teachers and their students were subsequently obseved during lessons involving an electricity unit, queried both students and teachers concerning the appropriateness of different fields of science for boys and girls and their interest and aptitudes in doing various types of science. Results from both studies suggest that gender differences in student attitudes toward science may be amellorated by specific types of teacher workshop.

The characteristics of effective english teachers as perceived by high school teachers and students in Korea

This study investigated the characteristics of effective English teachers as perceived by 169 teachers and 339 students in high school in Korea, with a self-report questionnaire consisting of three categories: English proficiency, pedagogical knowledge, and socio-affective skills. Overall, the teachers perceived significantly different characteristics than the students in all three categories with the teachers ranking English proficiency the highest in contrast to the students who ranked pedagogical knowledge the highest. The student subgroups also held different perceptions of effective teaching. High achieving students reported different characteristics than low achieving students in pedagogical knowledge and socio-affective skills, whereas the male students demonstrated different characteristics from the female students in socio-affective skills. The findings have implications for knowledge-based teacher education for current and prospective English teachers.     

Supporting children’s mathematical understanding: professional development focused on out-of-school practices

This study describes the Reflection Connection Cycle professional development designed to support teachers’ use and appreciation of students’ out-of-school practices related to school mathematics. The year-long program incorporated group lesson design, readings, and video analysis for 14 elementary school (ages 5–12) teachers. Analysis of lesson development, written reflections, and analysis of teacher talk revealed important patterns related to the difficulty in writing lessons that built on students’ informal understandings. While initial lessons focused solely on the context of practices like gardening and sports, subsequent lessons show a greater concern for the mathematics in which children were engaged within a practice. A Multi-approach Engagement Framework is presented both as a tool to support further professional development efforts and as a means to describe stability and change in teachers’ efforts to connect in-school and out-of-school mathematical understandings.     

The key factors affecting students’ individual interest in school science lessons

Individual interest in school science lessons can be defined as a relatively stable and enduring personal emotion comprising affective and behavioural reactions to events in the regular science lessons at school. Little research has compared the importance of different factors affecting students’ individual interest in school science lessons. The present study aimed to address this gap, using a mixed methods design. Qualitative interview data were collected from 60 Hong Kong junior secondary school students, who were asked to describe the nature of their interest in science lessons and the factors to which they attribute this. Teacher interviews, parent interviews, and classroom observations were conducted to triangulate student interview data. Five factors affecting students’ individual interest in school science lessons were identified: situational influences in science lessons, individual interest in science, science self-concept, grade level, and gender. Quantitative data were then collected from 591 students using a questionnaire. Structural equation modelling was applied to test a hypothesised model, which provided an acceptable fit to the student data. The strongest factor affecting students’ individual interest in school science lessons was science self-concept, followed by individual interest in science and situational influences in science lessons. Grade level and gender were found to be nonsignificant factors. These findings suggest that teachers should pay special attention to the association between academic self-concept and interest if they want to motivate students to learn science at school.     

Using online glossing lessons for accelerated instruction in ASL for preservice deaf education majors

Teachers of deaf and hard of hearing students must serve as language models for their students. However, preservice deaf education teachers typically have at most only four semesters of American Sign Language (ASL) training. How can their limited ASL instructional time be used to increase their proficiency? Studies involving deaf and hard of hearing students have revealed that glosses (written equivalents of ASL sentences) can serve as "bridges" between ASL and English. The study investigated whether glossing instruction can facilitate hearing students' learning of ASL. A Web site was developed in which ASL glossing rules were explained and glossing exercises provided. Posttest scores showed the experimental group improving from 39% to 71% on ASL grammar knowledge. These findings indicate that online glossing lessons may provide the means to obtain ASL skills more readily, thus preparing deaf education teachers to serve as ASL language models.     

The development and validation of an alternative assessment to measure changes in understanding of the longleaf pine ecosystem

A drawing assessment to gauge changes in fourth grade students’ understanding of the essential components of the longleaf pine ecosystem was developed to support an out-of-school environmental education program. Pre- and post-attendance drawings were scored with a rubric that was determined to have content validity and reliability among users. In the specific context of this intervention, the assessment documented significant growth in the understanding of the essential components, processes, flora and fauna of the ecosystem. This assessment found no significant differential advantage with respect to gender or dominance status of the students and is offered as an alternative to traditional assessments that favor select groups. Extensions of this framework to other ecosystems, and implications for in-service/pre-service educators and science proficiency, are discussed.     

Effects of background and classroom characteristics on the science achievement of 10-year-old students

Effects of characteristics of science classrooms on the science achievement of students were examined in the context of a simple model. The model incorporated prior attributes of the students in terms of home background, sex, and verbal and quantitative ability. The model was estimated by means of partial least squares multivariate procedures using data for 10-year-old Queensland students from the Second International Science Study. The results demonstrated the dominant influence of home background and verbal/mathematical ability. Female students tended to have lower scores after allowing for the influence of the other variables in the model. Students who stated that there were more student initiated activities in their science lessons tended to have lower achievement.

Authentic Science Research in Elementary School After-School Science Clubs

In this paper we report on teachers’ and students’ participation in authentic science research in out of school time science clubs at elementary schools. In the program four to five teachers worked alongside practicing scientists as part of their research groups. Each teacher facilitated a club with 10–15 students who, by extension, were members of the scientists’ research groups. Over the 3 years of the project nearly 30 teachers and over 500 children participated in the clubs. In this paper we present a case study of teachers and children who worked with an analytic chemist at a major university whose field of research is environmental arsenic. We illustrate how the professor mentored the teachers and how they in turn mentored the children. We show how the elementary school teachers who had very little formal science education gained the expertise needed to mentor the children. We found that in less than one academic year the teachers were able to gain the knowledge and skills to facilitate the children’s legitimate participation in authentic scientific research; and that the children gained the methodological and intellectual proficiency needed to contribute useful data and findings to the scientist’s research program.     

Career education attitudes and practices of K-12 science educators

A random sample of 400 K-12 science educators who were members of the National Science Teachers Association were surveyed regarding their attitude toward and practice of career education in their science teaching. These science teachers rejected a narrowly vocational view, favoring instead a conception of career education which included self-perception, values analysis, and vocational skills objectives. The science educators affirmed the importance of career education for a student's education, asserted career education ought to be taught in their existing science courses, and expressed a willingness to do so. Fewer than one-third of the science teachers, however, reported incorporating career education at least on a weekly basis in their science lessons. The major impediment to including more career education in science teaching was seen to be their lack of knowledge of methods and materials relevant to science career education, rather than objections from students, parents, or administrators; their unwillingness; or their evaluation of career education as unimportant. Thus, in order to improve this aspect of science teaching, science teachers need more concrete information about science career education applications.
