Reasoning from data: How students collect and interpret data in science investigations

This study explored the understandings of data and measurement that school students draw upon, and the ways that they reason from data, when carrying out a practical science inquiry task. The two practical tasks used in the study each involved investigations of the relationships between two independent variables (IVs) and a dependent variable (DV); in both tasks, one IV covaried with the DV, whereas the other did not. Each was undertaken by 10 students, aged 10, 12, and 14 years (total n = 60 students), working individually. Their actions were video‐recorded for analysis. In a subsequent interview, each student was asked to discuss and interpret data collected by two other students, undertaking a similar (but different) practical task, shown on a video‐recording. An analysis of the sample students' performance on the practical tasks and their interview responses showed few differences across task contexts, or with age, in students' reasoning, but significant differences in performance when investigating situations of covariation and non‐covariation. Few students in the sample displayed sufficient understanding of measurement error to deal effectively with the latter. Investigations of non‐covariation cases revealed, much more clearly than investigations of covariation cases, the students' ideas about data and measurement, and their ways of reasoning from data. Such investigations therefore provide particularly valuable contexts for teaching and research. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 748–769, 2004     

Community College Students' Conceptual Understanding of Statistical Measures of Spread

This study investigated the conceptual understanding of measures of spread among community college students in an introductory statistics course. The course is centered around deemphasizing computational skills and focused, rather, on development of conceptual understanding. Open-ended questions were developed to explore and assess students' conceptual understanding of measures of spread. A detailed analysis of the students' responses is presented to reveal the range of students' conceptions of the measures of spread. The analysis of a wide variety of responses provides evidence of the students' ability to organize concepts of spread in a way that is meaningful to them individually. Some common student misconceptions revealed by this study should be examined closely and taken into consideration to promote students' development of understanding of spread.     

Relationships between students' meaningful learning orientation and their understanding of genetics topics

This study explored factors predicting the extent to which high school students (N = 140) acquired meaningful understanding of the biological topics of meiosis, the Punnett-square method, and the relationships between these topics. This study (a) examined mental modeling as a technique for measuring students' meaningful understanding of the topics, (b) measured students' predisposed, generalized tendency to learn meaningfully (meaningful learning orientation), (c) determined the extent to which students' meaningful learning orientation predicted meaningful understanding beyond that predicted by aptitude and achievement motivation, (d) experimentally tested two instructional treatments (relationships presented to students, relationships generated by students), (e) explored the relationships of meaningful learning orientation, prior knowledge, instructional treatment, and all interactions of these variables in predicting meaningful understanding. The results of correlations and multiple regressions indicated that meaningful learning orientation contributed to students' attainment of meaningful understanding independent of aptitude and achievement motivation. Meaningful learning orientation and prior knowledge interacted in unique ways for each topic to predict students' attainment of meaningful understanding. Instructional treatment had relatively little relationship to students' acquisition of meaningful understanding, except for learners midrange between meaningful and rote. These findings imply that a meaningful learning approach among students may be important, perhaps as much or more than aptitude and achievement motivation, for their acquisition of interrelated, meaningful understandings of science.     

Economic aspects of citizenship education: an investigation of students' understanding

In 2002 education for citizenship will become a statutory requirement in English secondary schools for the first time. Broad guidelines which have been issued to schools include some elements of economic understanding, although this aspect of citizenship has attracted little attention in public debate. Moreover, relatively little is known about students' current thinking on these aspects of citizenship. Our article addresses this gap in current knowledge through reporting results from a large-scale (over 1000 responses) survey of 15- and 17-year-old students. A draft survey was trialled in May 2000 and revised in the light of students' responses and discussion at a research seminar in July 2000. The questionnaire focuses on students' understanding of, and attitude towards, aspects of taxation, government spending, employment and inflation. These results may usefully inform planning for programmes of citizenship education and they can also provide a point of reference for subsequent evaluation of those programmes.     

Interpretive responses to images in picture books by primary and secondary school students: Exploring curriculum expectations of a ‘visual grammatics’

As well as maintaining the central role of literature, the new Australian Curriculum: English emphasises the multimodal nature of literacy and requires students in primary and secondary schools to develop explicit knowledge about visual and verbal grammar as a resource for text interpretation and text creation. This study investigated the use of visual grammatics in interpreting picture books by students across Years Four, Five, Seven and Ten following an intensive professional learning programme undertaken by their teachers. A proposed framework describes variation in students' interpretive stance from tactical to diegetic to semiotic. Levels of student semiotic understanding are differentiated and differences between students' oral and written interpretations are discussed in relation the need for explicit teaching of written interpretive responses to multimodal literary texts, drawing on an articulated visual and verbal grammatics appropriate to the teaching of English in primary and secondary schools.     

Useful interactive teaching tool for learning: clickers in higher education†

Many university lecturers are encouraged to implement innovative teaching tools and methodologies such as clickers in order to create an interactive learning environment and improve student learning, but its performance must be evaluated. The aim of this paper is to test empirically the impact of the use of clickers on students' learning processes. The teaching experience applied to the subject of Financial Accounting is specifically described. The total sample size is 77 students from a Business Administration and Economics Degree, taught in English and in Spanish. The analysis, using multivariate techniques, of the questionnaire responses, students' grades and a reflexive experience of the lecturer conclude that learning with clickers is effective. There is a positive relationship between grades and intrinsic motivation through clickers. Consequently, the students' marks are related to its intrinsic motivation, feedback to understanding, students' discussion and its negative aspects but not gender nor age.     

The role of written formative feedback in inducing non-formal learning among masters students

This article adds to the existing literature on nonformal learning in education in general and the role played by written feedback in providing the space for such learning in particular. The study was conducted in an English as a Foreign Language context in which the participating students received written feedback on their English writings. Employing qualitative interviews and stimulated recall methodology, we explored interstudent interactions, cross-cultural understanding, and initiation into communities of practice, and categorized these as reactive and deliberative types of nonformal learning. Drawing upon Eraut's typology of nonformal learning, we would argue that formative written feedback provided on students' writings could lead to nonformal learning because it encourages them to act upon it.     

Scaffolding Students’ Online Critiquing of Expert- and Peer-generated Molecular Models of Chemical Reactions

In this study, we developed online critiquing activities using an open-source computer learning environment. We investigated how well the activities scaffolded students to critique molecular models of chemical reactions made by scientists, peers, and a fictitious peer, and whether the activities enhanced the students' understanding of science models and chemical reactions. The activities were implemented in an eighth-grade class with 28 students in a public junior high school in southern Taiwan. The study employed mixed research methods. Data collected included pre- and post-instructional assessments, post-instructional interviews, and students' electronic written responses and oral discussions during the critiquing activities. The results indicated that these activities guided the students to produce overall quality critiques. Also, the students developed a more sophisticated understanding of chemical reactions and scientific models as a result of the intervention. Design considerations for effective model critiquing activities are discussed based on observational results, including the use of peer-generated artefacts for critiquing to promote motivation and collaboration, coupled with critiques of scientific models to enhance students' epistemological understanding of model purpose and communication.     

The Effects of Glossary and Read-Aloud Accommodations on English Language Learners’ Performance on a Mathematics Assessment

Glossary and reading aloud test items are commonly allowed in many states' accommodation policies for English language learner (ELL) students for large-scale mathematics assessments. However, little research is available regarding the effects of these accommodations on ELL students' performance. Further, no research exists that examines how students use the accommodations. Using a randomized experimental design and think-aloud procedure, the present study explored the effects of the two accommodations. Results showed no significant effect of glossary, mixed effects of read aloud, and significant interaction effects between students' prior content knowledge and accommodations, which suggests the accommodation was effective for students with content knowledge. Think-aloud data indicated that students were not familiar with, and did not actively utilize the glossary. Implications for the effective use of accommodations and future research are discussed.     

Thinking outside the (voice) box: A case study of students' perceptions of the relevance of anatomy to speech pathology

Speech pathology students readily identify the importance of a sound understanding of anatomical structures central to their intended profession. In contrast, they often do not recognize the relevance of a broader understanding of structure and function. This study aimed to explore students' perceptions of the relevance of anatomy to speech pathology. The effect of two learning activities on students' perceptions was also evaluated. First, a written assignment required students to illustrate the relevance of anatomy to speech pathology by using an example selected from one of the four alternative structures. The second approach was the introduction of brief “scenarios” with directed questions into the practical class. The effects of these activities were assessed via two surveys designed to evaluate students' perceptions of the relevance of anatomy before and during the course experience. A focus group was conducted to clarify and extend discussion of issues arising from the survey data. The results showed that the students perceived some course material as irrelevant to speech pathology. The importance of relevance to the students' “state” motivation was well supported by the data. Although the students believed that the learning activities helped their understanding of the relevance of anatomy, some structures were considered less relevant at the end of the course. It is likely that the perceived amount of content and surface approach to learning may have prevented students from “thinking outside the box” regarding which anatomical structures are relevant to the profession.

Promoting cross‐cultural awareness and understanding: incorporating ethnographic interviews in college EFL classes in Taiwan

The emergence of the incorporation of culture into EFL education is a growing trend in Taiwan. The purpose of the study was to examine: (1) the effects of the ethnographic interview project on Taiwanese students' cognitive development in understanding native English speakers and their cultures; (2) changes in students' self‐awareness and understanding of both the target culture and their own; and (3) students' perceptions of the ethnographic interview project employed in EFL college classes. Data were collected through pre–post questionnaires, oral and written reports, classroom observation and interviews. Results indicated that participation in the ethnographic interview project helped facilitate the development of cross‐cultural awareness and communication skills by providing opportunities for students to gain insight into the values of target language countries, learn to view their own culture in new ways, increase their confidence in using English to communicate and view authentic communication as the goal of EFL learning. The majority of the participants saw the ethnographic interview project as an effective means of facilitating intercultural/interpersonal communication and understanding.     

Teaching the book and educating the person: challenges for university English language teachers in China

Recent accounts of college-level English language teaching in China describe environments that, although constrained by the College English Test (CET), are undergoing changes in a number of curriculum areas, including recognition of the need to incorporate communicative approaches and the assessment of practical language abilities. In such times, tensions between the needs and desires of society, teaching institutions, teachers and students are inevitable. In this article, we report on a study involving a group of university English teachers from across China who attended a professional development programme in Beijing in the summer of 2006. We explored the experiences of 83 teachers in their working environments, using four one-page reflective frames, which we distributed at regular intervals during the 2-week programme. Teachers described tensions between the need to achieve socially-oriented and subject-centred goals, such as passing examinations and developing communicative competence (“teaching the book”), and their desire to bring about enduring personal changes in students' awareness of themselves as learners and their approaches to learning (“educating the person”). Like colleagues in other countries and contexts, they faced ongoing challenges in trying to harmonize students' needs, curriculum obligations, and their own theories of best practice.     

Korean Students' Perceptions of Scientific Practices and Understanding of Nature of Science

Korean students have shown relatively little interest and confidence in learning science, despite being ranked in the top percentile in international evaluations of academic achievement in science such as the Trends in International Mathematics and Science Study. Although research indicates a positive relationship between student perceptions of science and their science learning, this area has not been sufficiently explored in Korea. Particularly, even though both students' perceptions of scientific practice and their understanding of the nature of science (NOS) are influenced by their science learning experiences at schools, little research examines how this perception, understanding, and experience are related to one another. This study aimed to uncover Korean students' perceptions of school scientific practice through exploring their drawings, writings, and responses to questionnaires. Participants were 500 Korean students in 3rd, 7th, and 10th grades who were asked to complete an open-ended questionnaire. The results indicated that Korean students typically viewed school scientific practices as experimental activities or listening to lecture; and that most participants held an insufficient understanding of the NOS. Overall, no significant relationship emerged between students' perceptions of school scientific practice and their understanding of the NOS. Our findings highlight the need to help both teachers and students understand the potential breadth of school scientific practices, beyond simple ‘activity mania.’ This study also suggests that teachers must balance implicit and explicit instructional approaches to teaching about the NOS through scientific practices in school science contexts.     

Phantom and big-fish-little-pond-effects on academic self-concept and academic achievement: Evidence from English early primary schools

The Big-Fish-Little-Pond Effect (BFLPE) suggests that school-average achievement has a negative effect on academic self-concept (ASC); some research has also verified a negative effect on students' academic achievement. Our study evaluates the compositional effects of school-average achievement on both outcomes, using a longitudinal sample of English early primary school students in Year 1 and Year 4. We provide evidence for BFLPEs in children as young as six to nine years of age. Further, we show that the BFLPE is a potential mechanism in the negative compositional effect of school average achievement in Year 1 on students' achievement in Year 4. Once adjustments for measurement error are made, the negative effect of school-average achievement on students' self-concept, and on their subsequent achievement, becomes even more negative. Our findings question previous research suggesting that attending a school with higher average achievement necessarily advances students’ outcomes.     

Frameworks for Language Study at A Level

This article argues that students of language study at A level need opportunities to build a broad foundation for exploring language experience, familiar issues and accessible concepts using practical activities and informal discussion if they are to develop their understanding of the more formal and systematic aspects of language theory. Teachers need familiarity with the staging points which correspond to different levels of students' understanding, and access to frameworks for language study which are sufficiently detailed to enable them to recognise growth points and build on students' achievements.     

Developing understanding through confronting varying views: The case of solving qualitative physics problems

This study explored high school students' collaborative efforts in solving qualitative physics problems. It aims to investigate whether and how confronting students with varying views help to improve their problem solving skills and develop better understanding of the underlying physics concepts. The varying views were provided to 18 Year 12 students by requiring them (a) to work in dyads on three problems during which they had to consider and confront each other's ideas; and (b) to consider, in a feedback session, multiple solutions to each problem, comparing the solutions with their own and reflecting on their mistakes. The study adopts Marton's emerging theory of awareness as its theoretical underpinning- that the varying views would bring to students' focal awareness and enable them to discern the different critical aspects of the problem situations and this would help them to develop conceptual understanding. The results show that confronting students with varying views have positive effects on students' learning, thus lending support to the theory of awareness.     

An exploration of Illinois students' attitudes toward science using multivariate multilevel modeling with a cross-sectional sample of responses from grades 5 through 10

The present study examined students' attitudes toward science and associated constructs, based on the theories of reasoned action and planned behavior, and explored relationships between individual and school-related variables common to the research literature. Responses from 1,291 students in Grades 5 through 10 were collected using the 30-item Behaviors, Related Attitudes, and Intentions toward Science (BRAINS) Survey along with background information questions. Additional self-report data were collected from teachers (n = 56; 82.4%) in participating schools (n = 68) to obtain information about their education and experience, characteristics and practices, as well as other classroom variables, which could influence students' outlook. Student information, teacher data collected, and other data compiled about participating schools, were used to explore patterns in students' attitudes, beliefs, and intentions. These variables were used to generate multivariate multilevel models through a forward construction process. The final model presented favors individual variables to explain differences in students' responses on all five of the BRAINS subscales, more than group-level variables captured. Of the predictor variables explored, students' perceived science ability and frequency of talk with family were influential on all subscales, and increasing these variables had a positive effect on the estimated mean scores according to the final model presented. Findings from this study also include commonly observed relationships, such as the decline in attitudes over time, but these were found to be less pervasive in this sample. The paper concludes with a discussion about the comparative ineffectiveness of teacher and school-related variables in explaining students' attitudes toward science in this study, in light of design decisions and limitations, to guide future investigations.     

Differential relations of constructivist and didactic instruction to students' cognition,motivation, and achievement

This study examined how constructivist and didactic instruction was related to students' cognitive, motivational, and achievement outcomes in English classrooms, using a sample of 3000 Grade 9 students from 108 classrooms in 39 secondary schools in Singapore. Results of hierarchical linear modeling showed differential cross-level relations. After controlling for students' prior achievement, constructivist instruction was a significant positive predictor of students' deep processing strategies, self-efficacy, task value, and English achievement, whereas didactic instruction was a significant positive predictor of students' surface processing strategies and a negative predictor of English achievement. Our findings underscore the importance of linking instructional practices with multiple outcomes, including psychological factors that are important for student learning.     

How does Donor Dissection Influence Medical Students' Perceptions of Ethics? A Cross-Sectional and Longitudinal Qualitative Study

The contribution of donor dissection to modern anatomy pedagogy remains debated. While short-term anatomy knowledge gains from dissection are questionable, studies suggest that donor dissection may have other impacts on students including influencing medical students' professional development, though evidence for such is limited. To improve the understanding of how anatomy education influences medical student professional development, the cross-sectional and longitudinal impacts of donor dissection on medical students' perceptions of ethics were explored. A cross-sectional and longitudinal qualitative study was undertaken at an Australian university where student responses to online discussion forums and in-person interviews were analyzed. Data were collected across the 1.5 years that undergraduate medical students received anatomy instruction (three semesters during first and second years). A total of 207 students participated in the online discussion forums, yielding 51,024 words; 24 students participated in at least 1 of 11 interviews, yielding over 11 hours of interview data. Framework analysis identified five themes related to ethics in an anatomical education context: (1) Dignity, (2) Beneficence, (3) Consent, (4) Justification for versus the necessity of dissection, and (5) Dichotomy of objectification and personification. The dominant themes of students' ethical perceptions changed with time, with a shift from focusing on donors as people, toward the utility of donors in anatomy education. Additionally, themes varied by student demographics including gender, ancestry, and religiosity. Together this study suggests a strong impact of donor dissection on priming students' focus on medical ethics and provides further advocacy for formal and purposeful integration of medical ethics with anatomy education.     

Patterns and Factors of High School Dropout Risks of Racial and Linguistic Groups

This study examined the dropout trajectories of racial and linguistic minority students and explored the effects of students' contextual factors on their high school dropout risks. Our motivation was to identify the dropout patterns of Black, Hispanic, and Hispanic English language learner (ELL) students, who have comparatively high dropout rates, and to suggest ways to promote high school completion. We employed a survival analysis using the National Longitudinal Survey of Youth 1997 (NLSY97) from the U.S. Bureau of Labor Statistics. The results showed that the 3 minority groups displayed significantly higher dropout risks than the White group. The overall pattern of dropout risks increased over time, with the dropout rates of the Black students high in the 1st and 2nd years of high school and the highest dropout rates for Hispanic ELL students in their senior year. A gender difference was found among the students, with male students having higher dropout risks than female students. It was also found that students' positive relationships with their teachers were associated with lower dropout risks.
