The Nature of Science and Science Education: A Bibliography

Research on the nature of science and science education enjoys a longhistory, with its origins in Ernst Mach's work in the late nineteenthcentury and John Dewey's at the beginning of the twentieth century.As early as 1909 the Central Association for Science and MathematicsTeachers published an article – A Consideration of the Principles thatShould Determine the Courses in Biology in Secondary Schools – inSchool Science and Mathematics that reflected foundational concernsabout science and how school curricula should be informed by them. Sincethen a large body of literature has developed related to the teaching andlearning about nature of science – see, for example, the Lederman (1992)and Meichtry (1993) reviews cited below. As well there has been intensephilosophical, historical and philosophical debate about the nature of scienceitself, culminating in the much-publicised Science Wars of recent time. Thereferences listed here primarily focus on the empirical research related to thenature of science as an educational goal; along with a few influential philosophicalworks by such authors as Kuhn, Popper, Laudan, Lakatos, and others. Whilenot exhaustive, the list should prove useful to educators, and scholars in otherfields, interested in the nature of science and how its understanding can berealised as a goal of science instruction. The authors welcome correspondenceregarding omissions from the list, and on-going additions that can be made to it.     

From Cognitive-Domain Theory to Assessment Practice

This article exemplifies how assessment design might be grounded in theory, thereby helping to strengthen validity claims. Spanning work across multiple related projects, the article first briefly summarizes an assessment system model for the elementary and secondary levels. Next the article describes how cognitive-domain theory and principles are used in the design of a scenario-based summative assessment for argumentation in the English language arts. Finally, results from several psychometric approaches are used to evaluate propositions suggested by the domain theory, including ones related to the use of topical scenarios and learning progressions in assessment design. Although results generally supported these propositions, the work described represents only a small step in a long-term, iterative process of theory development, assessment design, and empirical tryout, which should, in principle, lead to more valid assessments that better inform teaching and learning.     

Understanding How First-year Seminars Affect Persistence

First-year seminars are nearly ubiquitous fixtures in American higher education, and research has documented their positive effect on student persistence. Only limited research, however, has attempted to isolate the impact of various aspects of first-year seminars on persistence, especially on a cross-institutional basis. We use a survey of almost 20,000 first-year students at 45 four-year institutions combined with institutional-level data to understand how aspects of first-year seminars affect early intentions to persist. Because survey respondents are grouped within dissimilar institutions, we use a multilevel modeling approach to model intent to persist.     

Choice of operation in verbal problems with decimal numbers

This article examines the conceptual problems that children experience when attempting to solve verbal problems which contain decimal numbers. After discussing the existing research, we then describe an experiment that was designed in three phases:

1. Exploratory interviews to discover existing conceptions and difficulties and to discover how pupils made use of diagrams, simpler numbers, and strategies. These interviews exposed difficulties with the understanding of place value, the effect of multiplying and dividing by a positive number less than one, the symbolisms of division and its noncommutative nature, the units associated with the numbers and also with familiar names for the operations. The three strategies were all found to be unfamiliar to pupils and their difficulties are discussed.
2. The design and administration of a diagnostic test, based on the results of these interviews, to a class of less able 14 year olds.
3. The preparation and use of calculator enriched teaching materials designed to remedy the identified misconceptions. From the pre- and post-test results we note the dramatic success of the teaching in improving pupils' understanding of place value, although there is a more modest improvement in enabling pupils to choose the correct operation by drawing diagrams, using easier numbers and estimating.

     

The benefits of peer observation of teaching for tutor development

Peer observation partnerships can help teachers improve their teaching practice, transform their educational perspectives and develop collegiality (Bell 2005). This paper describes the peer observation model used in the tutor development program in the Faculty of Economics and Business at the University of Sydney, and reports on the effectiveness of this exercise using quantitative and qualitative data from five sources. Results from 32 peer observations reveal both the common strengths and the areas in which tutors need to develop their teaching practice. Ninety four percent of participants found the exercise valuable and 88% said that they would change their teaching as a result of the exercise. This model can be applied in academic development programs in any discipline and suggestions for augmentation and improvement are provided.

Development and Evaluation of a Computer Literacy Course for Preservice Teachers in Singapore

The problem was to identify topics and concepts for a computer literacy course for preservice teachers in Singapore, to develop curriculum materials, and to evaluate the course in terms of achievement, attitudes towards computers, and reactions to the course by the participants.

The syllabus was designed and curriculum materials were developed for the course. The results of the study showed that the course had been effective in raising the computer literacy achievement of the preservice teachers but not attitudes towards computers. Reactions to the course were favourable and hands-on experience on the computer was considered the most effective aspect of the course.     

Cattell‐Horn‐Carroll broad cognitive ability profiles of low math achievers

This study extends previous research examining the relations between Cattell‐Horn‐Carroll cognitive abilities and math achievement. The cognitive profiles of children with normative weaknesses in Math Calculation Skills or Math Reasoning were compared to those of their average‐achieving peers. The cognitive profile of the low Math Calculation Skills group (n = 68) was similar to that of their average‐achieving peers. The low Math Reasoning group (n = 52) scored lower than their average‐achieving peers on the cognitive abilities as a set and on Fluid Reasoning and Comprehension–Knowledge. When individual profiles were considered, approximately half of the children with normative math weaknesses demonstrated commensurate weaknesses in one or more cognitive abilities, which may inform diagnostic models of learning disabilities. © 2005 Wiley Periodicals, Inc.

Strategies for Assessing Classroom Teaching: Examining Administrator Thinking as Validity Evidence

All 50 states use observations to evaluate practicing teachers, but we know little about how administrators actually reason when they use those observation protocols. Drawing on think-aloud and stimulated recall data, this study describes the types of strategies and warrants practicing administrators used when rating with their district’s observation protocol. Administrators in a large urban district used an observation protocol aligned to Danielson’s Framework for Teaching to rate a brief lesson clip. Administrators’ thinking was recorded, clarified, and inductively coded. Findings suggest administrator thinking and justification is complex even for short lengths of instruction. Administrators used a range of reasoning strategies, many of which were not sanctioned by their training. Exploratory analyses suggest strategy use was not related to the accuracy of ratings. Implications for the validity of teacher observation scores in high-stakes settings are considered.
