Multiple Aims in the Development of a Major Reform of the National Curriculum for Science in England

In the context of a major reform of the school science curriculum for 14–16‐year‐olds in England, we examine the aims ascribed to the reform, the stakeholders involved, and the roles of differing values and authority in its development. This reform includes an emphasis on socioscientific issues and the nature of science; curriculum trends of international relevance. Our analysis identifies largely ‘instrumental’ aims, with little emphasis on ‘intrinsic’ aims and associated values. We identify five broad categories of stakeholders focusing on different aims with, for example, a social, individual, political, or economic emphasis. We suggest that curriculum development projects reflecting largely social and individual aims were appropriated by other stakeholders to serve political and economic aims. We argue that a curriculum reform body representing all stakeholder interests is needed to ensure that multiple aims are considered throughout the curriculum reform process. Within such a body, the differentiated character of the science teaching community would need to be represented.     

Cognitive development in undergraduate emerging adults: How course-taking breadth supports skill formation

Theories of cognitive development among emerging adults posit that environmental and age-related influences are responsible for individual differences in complex reasoning abilities. Exposure to and engagement with a diverse set of ideas and perspectives is stipulated to provide a context for which individuals are positioned to coordinate, integrate, and form new abstractions. This notion is implicit in the general education and elective requirements of university programs. In this study, we draw upon the cognitive psychology literature on emerging adult development to examine how intellectual breadth via course-taking patterns relates to gains in cognitive skills. Using recently collected longitudinal data of undergraduates enrolled at a large public university, we leverage a unique set of cognitive measures that tap a string of related constructs. We find moderate associations between intellectual breadth and reasoning skills, with notable differences across cognitive dimensions. Additionally, intellectual curiosity moderates the association between course breadth and cognition. Implications for theories of intellectual development are discussed in relation to undergraduate experiences.

The Use of Newspaper Articles as a Tool to Develop Critical Thinking in Science Classes

The aim of this research is to identify the difficulties experienced by secondary school students (aged 15–16) with the critical reading of newspaper articles with scientific content. Two newspaper critical reading activities in relation to the study of various scientific contents were designed and carried out in two schools (61 students in total), one with a student population from a medium to high social and economic bracket and the other with students from a medium to low social and economic bracket. These activities were designed taking into account the phases of the reading process: before, during and after reading. In order to analyse the difficulties ‘Elements of science critical reading’ were identified on the basis of the ‘Elements of reasoning’ of Paul and Elder and the categories proposed by Bartz C.R.I.T.I.C. questionnaire and a scale was drawn up. The results show that the activities designed were useful in helping students to read critically. We also rated very positively the instrument created to assess the students' answers: the scale based on the performance indicators of Paul and Elder. This instrument enabled us to detect the aspects of critical thinking where students have the most difficulties: identifying the writer's purpose and looking for evidence in a text. It was also shown that the stance taken in the articles also had an influence on the results.     

Empowerment in Science Curriculum Development: A microdevelopmental approach

This study characterizes how learning and teaching differs as the responsibility for choosing curriculum goals and the strategies to reach those goals shifts between teacher and the students. Three different pedagogical approaches were used with 125 seventh‐grade and eighth‐grade students. All three curricula focus on electromagnetism, and were taught by two teachers in different schools over a two‐week period. When students had control over the strategies employed to reach goals, their engagement stayed high. All three curricula advanced student understanding to some degree; however, large and significant gains were seen only for the pedagogy in which teachers set the specific learning goals and students had control over how to achieve them. Microdevelopment, a principle by which short‐term learning recapitulates the stages seen in long‐term developmental growth, is found to be a useful framework for curriculum development and for analyzing changes in student understanding. In general, initial “tinkering” activities are best followed by attempts at representing phenomena, only then to be followed by abstract conceptualization. On balance, we find that students benefit most from freedom to control the procedures that they generate in response to well‐structured goals presented by the teacher.     

Science Learning: A path analysis of its links with reading comprehension,question-asking in class and science achievement

The purpose of this research was to build and test a conceptual model of the complex interrelationships between students' learning in science (learning approaches and self-regulation), their reading comprehension, question-asking in class and science achievement. These variables were measured by means of a test and a series of questionnaires administered to 604 ninth-grade students, and the data collected were analysed using a correlational, cross-sectional design. Results of a path analysis indicated that (a) students’ self-regulated and intentional knowledge-constructing activity (self-regulated strategy use, deep approach and knowledge-building) were what chiefly accounted for their question-asking in class; (b) question-asking (high and low levels) was related directly to reading comprehension and indirectly, through its contribution to the this, to academic achievement; (c) reading comprehension was directly and negatively associated with surface approach and indirectly and positively related to deep approach and knowledge-building; and (d) some of these variables, particularly reading comprehension, accounted for academic achievement in science. This model explained nearly 30% of the variance in academic achievement and provided a substantial and distinctive insight into the web of interrelationships among these variables. Implications for future research and science teaching and learning are discussed (e.g. the importance of supporting students' efforts to learn science in a meaningful, active and self-regulated way and of improving their reading comprehension).

Communication about science in a traditional museum: visitors’ and staff’s perceptions

This study investigated visitors’ and staff’s perceptions about the communication of science in a traditional natural history museum. The research examined the science-related outcomes for adult visitors and explored visitors’ and staff’s ideas of science and how it is portrayed at the museum. Data were collected by questionnaire and interview from 84 staff and 102 visitors. Both groups held positive views about science, its importance and the need for everyone to understand it. Comparison of visitors’ pretest and posttest scores on the questionnaire revealed some significant changes, several suggesting a change to views about science that were less “scientific.” Most visitors thought that their ideas about science had not changed as a result of their visit, but they were positive about the museum as a place for learning science. Staff held more “scientific” views about the nature of science than did visitors; they recognized the potential of the museum to educate people about science, but felt it needed to be presented as more relevant and accessible, particularly in terms of science as a cultural practice. Neither staff nor visitors perceived that the museum stimulated visitors to think critically about science. While acknowledging that interpreting complex scientific knowledge into exhibits readily understood by lay visitors and displaying controversy are difficult, these challenges must be addressed if visitors are to be encouraged to think about science and the social, cultural and political contexts which shape it.

Her research interests include the wider community’s engagement with science in their everyday lives, and the development of community-based science projects.     

Motivational beliefs and cognitive processes in mathematics achievement, analyzed in the context of cultural differences: a Korean elementary school example

The relations among students’ motivational beliefs, cognitive processes, and academic achievement were investigated. A 51-item questionnaire together with a mathematics achievement test was administered to 459 fifth graders in Korean elementary school mathematics classrooms. Results indicated that, in general, students’ cognitive processes related closely to competence beliefs, task values, and achievement goals, and more importantly their success or failure in mathematics achievement was closely linked to competence beliefs, performance-avoidance goals, and persistence strategies. Positive evidence of performance-approach goals was observed in math learning relative to task goals. As expected, performance-avoidance goals turned out to be detrimental to students’ math learning. These findings are generally congruent with the motivational theories and support the position that students should be encouraged to adopt task goals and actively involve themselves in math class activities. However, it also behooves us to recognize the potential benefits of performance-approach goals in different cultural contexts, such as the Korean elementary school math classrooms.     

Scientific reasoning in elementary school children: Assessment and relations with cognitive abilities

The primary goal of this study was the broad assessment and modeling of scientific reasoning in elementary school age. One hundred fifty-five fourth graders were tested on 20 recently developed paper-and-pencil items tapping four different components of scientific reasoning (understanding the nature of science, understanding theories, designing experiments, and interpreting data). As confirmed by Rasch analyses, the scientific reasoning items formed a reliable scale. Model comparisons differentiated scientific reasoning as a separate construct from measures of intelligence and reading skills and revealed discriminant validity. Furthermore, we explored the relationship between scientific reasoning and the postulated prerequisites inhibitory control, spatial abilities and problem-solving skills. As shown by correlation and regression analyses, beside general cognitive abilities (intelligence, reading skills) problem-solving skills and spatial abilities predicted performance in scientific reasoning items and thus contributed to explaining individual differences in elementary school children's scientific reasoning competencies.     

Elementary Teachers' Classroom Practices and Beliefs in Relation to US Science Education Reform: Reflections from within

This study unveils the stories of 3 public school elementary teachers from the USA who reflected on their beliefs about science education reform, and implementation of the reform in their classroom teaching, in response to state recommendations for change in science education. The teachers' stories show how various factors assisted or impeded the implementations of reform in their teaching, the various challenges related to their grade-level teaching, and the teachers' personal struggles to make sense of reform recommendations. Within each case study, we describe 4 common themes from the teachers' interviews. These themes are related to teachers' science teaching strategies, their science teaching efficacy beliefs about adopting reform, the types of science learning outcomes teachers target, and the types of teaching resources available to them. Implications for teacher education and practice are discussed in relationship with study findings.     

Science identity development trajectories in a gateway college chemistry course: Predictors and relations to achievement and STEM pursuit

This investigation of undergraduates’ heterogeneous science identity trajectories within a gateway chemistry course identified three latent classes (High and Stable, Moderate and Slightly Increasing, Moderate and Declining) using growth mixture modeling. Underrepresented minorities were more likely to exhibit Moderate-and-Slightly-Increasing science identities versus High-and-Stable patterns. Students with higher perceived competence were more likely classified into the High-and-Stable class compared to the other classes. Students classified into the High-and-Stable class scored significantly higher on the final exam and appeared to be more likely to remain in a STEM major across fall and spring semesters compared to the other two classes. Results suggest that some students’ identities shift within a single semester and supporting science perceived competence before college may support students’ science identity development.     

Level of Internet Use Among Science Teachers Involved in a Professional Development Project

This study examined the level of instructional use of Internet among science teachers involved with an in-service professional development project. An instrument on Level of Use of innovation was modified for the study. A criterion sample of teachers to be interviewed via telephone was randomly selected from a pool of 347 K–12 teachers. Somers' d and contingency coefficients were determined to see whether any relationship exists between a teacher's Level of Use and the following categories: (a) amount of experience with the Internet; (b) availability of resources support and access to the Internet in classroom and at home; (c) number of teacher and student users at school, (d) gender; and (e) type of school. Results of step-wise multiple regression indicate that classroom access, instructional experience of using Internet with students, availability of resource support and number of teacher users at school are the best predictors of teacher's Level of Use. Chi square test for comparisons between groups of completers and noncompleters of On-Line West Virginia K–12 RuralNet courses also revealed that a lack of classroom access to Internet and lack of resource/technical support at school contributed significantly to lower level of use among noncompleters.     

Children's school readiness in the ECLS-K: Predictions to academic, health, and social outcomes in first grade

Two studies examine patterns of school readiness in children at school entry and how these patterns predict first-grade outcomes in a nationally representative sample of first-time kindergartners from the Early Childhood Longitudinal Study—Kindergarten Class of 1998–1999 (N = 17,219). In Study 1, cluster analyses revealed four profiles at kindergarten entry: comprehensive positive development (30%), social/emotional and health strengths (34%), social/emotional risk (13%), and health risk (22.5% of the sample). Study 2 results suggested that children with one of the two “risk” profiles were more likely to be from families with multiple socioeconomic disadvantages. In addition, all four profiles differentially predicted academic and social adjustment in early elementary school. Children with a risk profile performed the worst on all outcomes; children with a comprehensive positive development profile performed the best. The authors discuss the need for early identification of children who may be at risk for entering school with few school readiness strengths.     

Inquiring into Teaching: Lesson Study in Elementary Science Methods

This article describes an innovative approach to developing preservice elementary science teachers’ classroom confidence and skills. Based on lesson study approaches, preservice candidates designed and taught integrated science–mathematics lessons during the semester before their student teaching. Working in teams, candidates designed and taught a common lesson in 3 different classrooms, critiquing and refining their lesson between each teaching activity. Data collected from observations of classroom teaching events, team reports, and individual reflections were analyzed qualitatively. Results indicate that, over the 3 teaching events, there were dramatic improvements in lesson design and delivery, the management of the learning environment, the quality of students’ engagements with meaningful content, and the quality of assessments and generation of student data. According to the website of the Lesson Study Research Group, there were more than 2,300 teachers in over 335 schools involved in lesson study in the U.S. as of May 2004 (www.tc.edu/lessonstudy/). Additional lesson study information, projects, and resources are available through a number of other websites, including www.lessonresearch.net (at Mills College) and www.uwlax.edu/sotl.lsp (at The University of Wisconsin–La Crosse)     

Expectancy-value and cognitive process outcomes in mathematics learning: a structural equation analysis

Existing research has yielded evidence to indicate that the expectancy-value theoretical model predicts students' learning in various achievement contexts. Achievement values and self-efficacy expectations, for example, have been found to exert positive effects on cognitive process and academic achievement outcomes. We tested a conceptual model that depicted the interrelations between the non-cognitive (task value, self-efficacy) and cognitive (deep-learning approach, reflective-thinking) processes of learning, and academic achievement outcomes in mathematics. University students (n = 289) were administered a number of Likert-scale inventories and LISREL 8.80 was used to test various a priori and a posteriori models. Structural equation modeling yielded some important findings: (1) the positive temporally displaced effects of prior academic achievement, self-efficacy expectations and task value on achievement in mathematics, (2) the positive relations between self-efficacy expectations and task values and cognitive process outcomes and (3) the possible mediating role of self-efficacy expectations and task value between prior academic achievement and deep learning, reflective-thinking practice and academic achievement. Overall, our research investigation has provided empirical groundings for further advancement into this area of students' learning.
