Multicultural chemistry and the nature of science: but what about knowledge?

In response to Goff, Boesdorfer, and Hunter??s article on the use of a multicultural approach to teaching chemistry and the nature of science, I forward this critical reflective essay to discuss more general curriculum aspects of the relationship between the nature of science and science education in school contexts. Taking a social realist perspective, I argue for a more nuanced understanding of the role of epistemology and ontology in science classrooms, and for a reconsideration of the role of knowledge in science classrooms.     

The exclusive language of science? Comparing knowledge gains and motivation in English-bilingual biology lessons between non-selected and preselected classes

The dominant role of English as the global language of science entails a requirement for science teachers to equip their non-native English-speaking students with receptive and productive language skills for communication in scientific contexts. Although science courses with English elements are part of some schools’ bilingual programmes, they are usually not available to a wider student audience, but are restricted to high achieving or highly motivated students. The present study was to test whether a newly developed biology content and language integrated learning (CLIL) unit could also benefit standard ninth grade classes. The learning gains and motivation of bilingually inexperienced students were compared to those of a preselected group and a comparison group that had been taught solely in their native language. All participating classes achieved similar gains in content knowledge, and the standard students rated their motivation for bilingual science lessons as positive, albeit not as high as the preselected group. We thus provide evidence against concerns that teaching non-selected students bilingually might lead to deficits in content knowledge acquisition. Following this, we conclude that scientific English should be a part of standard science lessons regardless of specific school programmes.     

Who uses a means-tested scholarship,and what do they choose?

This paper provides detailed evidence regarding the nature of selection into a school voucher system. We use micro-data on scholarship applications matched with state student-level records on test scores, schools attended, and demographic background characteristics to describe the attributes of students who choose to participate in Florida's Corporate Tax Credit Scholarship Program, a means-tested scholarship program that is the largest of its type in the United States. We find evidence that those who choose to participate in the program tend to be lower-performing students from poorly performing schools, and that students of different backgrounds tend to choose different types of private schools. Students participating in the program tend to select schools that have more white students and fewer minority students, regardless of student race.     

Mastery goal,value and self-concept: what do they predict?

Background:?Students’ motivation is known to influence academic outcomes. However, there is a paucity of research showing the relative influences of motivational factors on short-term and long-term outcomes.

Purpose:?The study investigates the relative influences of motivational factors – mastery goal orientation, value of schooling, and academic self-concepts (perceived competence in and affect to schoolwork) on four outcomes – rule acceptance, identity, general self-efficacy and achievement.

Sample:?Students in grades 3 to 6 from six primary schools in the Sydney were surveyed (N = 979). The ages of the participants varied from 8 to 13 years (mean = 9.78).

Design and methods:?Students completed a questionnaire and literacy and numeracy achievement tests. Structural equation modelling was used to examine the paths from four predictors to four outcomes.

Results:?Whereas all four predictors were positively associated with all four outcomes, students’ mastery goal had stronger positive influences on self-efficacy and identity. Value, perceived competence and affect were found to influence outcomes in different ways – positive influences were found for value on achievement, rule-acceptance, and identity; for perceived competence on achievement and efficacy; and for affect on rule-acceptance and identity.

Conclusion:?Mastery goal had stronger influences on long-term outcomes while other predictors are stronger for short-term outcomes. To facilitate short-term and long-term outcomes, all four motivational factors need attention.     

School Leaders as Learners: what attitudes and preferences do they have?

Leadership development is a key issue for success in leading educational reform and school improvement. Demands for more flexible, responsive, and enterprise‐driven schooling require that school leaders can create the kind of conditions which sustain vigorous processes of continuous school improvement. To meet this requirement, school leaders must be in command of a broader range of leadership and management expertise than was traditionally required of them. The changing environments make it essential for school leaders to have a high level of awareness of their preferences for leadership development and a commitment to improve their professional performance. This paper discusses findings of a survey‐based study of school leaders’ attitudes and preferences for professional development in Western Australia. Surveys conducted among principals and deputy principals of primary (n = 233) and secondary (n = 180) schools reveal some important similarities, as well as differences, in the extent to which primary and secondary school leaders have recognized the potential for work‐based and peer‐assisted learning.     

Computer science in K-12 school curricula of the 2lst century: Why,what and when?

In this paper we have examined the position and roles of Computer Science in curricula in the light of recent calls for curriculum change and we have proposed principles and issues to consider in curriculum design as well as identifying priority areas for further research. The paper is based on discussions within and beyond the International Federation of Information Processing (IFIP) Education Community since 2012 as well as an analysis of curriculum developments in five different countries. Emerging themes have been discussed with reference to important perspectives from curriculum theory including “powerful knowledge” as a key element of entitlement and management of the growth of expertise. Based on this analysis we have identified areas of consensus as well as constraints, risks and issues that are still subject to controversy. There is an emerging consensus of the importance of Computer Science and the nature of its “powerful knowledge”. Furthermore current understanding of the opportunities and benefits for starting to learn Computer Science early in primary schools has identified this early start as an entitlement and equity issue. There is a strong consensus that teacher professional development in Computer Science Education is critical for supporting curriculum change and is currently a major challenge in many countries. Other key issues include understanding how the growth of expertise affects potential structure and sequencing in the curriculum and the balance of content. Further considerations include how new technological opportunities interact with pedagogical approaches and can provide new potential for the growth of expertise.     

So what exactly do you want? What principals mean when they say ‘male role model’

The need for more male role models in young boys’ lives is one of the main reasons underpinning the call for more male teachers in primary schools. However, the exact responsibilities and attributes associated with the term ‘male role model’ have yet to be clearly established. The purpose of this survey of 250 New Zealand primary school principals was to investigate the views of one major group of stakeholders to determine how principals defined male role models and what they considered the specific attributes of that role. The study found that the principals favoured men who exhibit a hegemonic masculinity couched in heterosexual, rugby‐playing, ‘real men’ attributes.     

Conflict between peers in infancy and toddler age: what do they fight about?

Although much psychological research has been conducted on children's conflicts with peers from as young as one year, very little attention has been paid to the question of the motivation underlying these conflicts. Nevertheless, what a child tries to achieve in a conflict can be highly relevant for understanding his/her conflict behavior, conflict resolution strategies, manner of coping with the outcome of conflicts, and impact of pedagogical intervention. Most researchers suppose that young children fight mainly over the possession of objects. In a longitudinal study, children were filmed during free play in daycare centers at ages 8, 14 and 22 months. Analyzing the film material employing qualitative methods, two different motivational themes at 8 months and an increasing variety of motivational issues at 14 and 22 months were identified. It was found that the earliest manifested and consistently dominant motivation is the need to explore, not to possess.     

What is science in preschool and what do teachers have to know to empower children?

In this article we problematize the purpose of teaching science in preschool and the competences preschool teachers need in order to conduct science activities in the classroom. The empirical data were collected through an action research project with five preschool and primary school teachers (K-6). In the first section of this paper we use one situation, a floating–sinking experiment, as an illustration of how two different epistemological perspectives generate different foci on which kind of science teaching competences can be fruitful in preschool settings. In the first perspective, the central goal of science teaching is the development of the children’s conceptual understanding. With this perspective, we found that the science activities with children were unsuccessful, because their thoughts about concepts did not develop as expected, the situation even enhanced a “misconception” concerning density. Moreover, the teacher was unsuccessful in supporting the children’s conceptual learning. The second perspective uses a feminist approach that scrutinizes science, where we investigate if the floating–sinking activity contributes to a feeling of participation in a scientific context for the children and if so how the teacher promotes this inclusion. This second perspective showed that the children’s scientific proficiency benefited from the situation; they had a positive experience with density which was reinforced by the teacher. The children discovered that they had power over their own learning by using an experimental approach. On the basis of these findings, we conclude that there are competences other than subject matter knowledge that are also important when preschool teachers engage children in scientific activities. Through process-oriented work with the teacher group, we identified four concrete skills: paying attention to and using children’s previous experiences; capturing unexpected things that happen at the moment they occur; asking questions that challenge the children and that stimulate further investigation; creating a situated presence, that is, “remaining” in the situation and listening to the children and their explanations. We discuss possible ways to move preschool teachers away from their feelings of inadequacy and poor self-confidence in teaching science by reinforcing this kind of pedagogical content knowledge.     

Women planning to major in computer science: Who are they and what makes them unique?

Despite the current growing popularity of the computer science (CS) major, women remain sorely underrepresented in the field, continuing to earn only 18% of bachelor’s degrees. Understanding women’s low rates of participation in CS is important given that the demand for individuals with CS training has grown sharply in recent years. Attracting and retaining more women to high-paying fields like CS may also help narrow the gender pay gap. Further, it is important that women participate in developing new technology so that technology advances serve the needs of both women and men. This paper explores the background characteristics, career aspirations, and self-perceptions of 1636 female first-year college students in the United States who intend to major in CS and compares them with 4402 male CS aspirants as well as with 26,642 women planning to major in other STEM sub-fields. The findings reveal a unique profile of women who pursue the CS major and notes many significant differences between men and women in CS and between women in CS and those in other STEM fields. For instance, women in CS tend to earn lower high school grades than women in other STEM fields, but earn higher SAT verbal scores. They also rate themselves higher than men in CS and women in other STEM fields on measures of their artistic ability, but rate themselves lower on other self-ratings, including academic and leadership ability. Further, women in CS are more likely to be undecided in their career plans than men in CS and women in other STEM fields. Understanding the unique characteristics of women in CS will help inform policies and recruitment programs designed to address the gender gap in computing.     

“Why do dogs pant?”: Characteristics of parental explanations about science predict children's knowledge

Using a new method for examining parental explanations in a laboratory setting, the prompted explanation task, this study examines how characteristics of parental explanations about biology relate to children's knowledge. Parents (N = 148; M_age = 38; 84% female, 16% male; 67% having completed college) of children ages 7–10 (M_age = 8.92; 47% female, 53% male; 58% White, 9.5% Black, 9.5% Asian) provided answers to eight how and why questions about biology. Parents used a number of different approaches to address the questions, including providing more mechanistic responses to how questions and more teleological responses to why questions. The characteristics of parental explanations—most notably, how frequently parents provided correct responses—predicted children's performance on measures of verbal intelligence and biological knowledge. Additional exploratory analyses and implications for children's learning are discussed.     

Fragile knowledge and conflicting evidence: what effects do contiguity and personal characteristics of museum visitors have on their processing depth?

Until recently, museums mainly communicated well-established knowledge. Current science, however, is characterized by a rapid knowledge increase, so that we often have to deal with fragile and inconsistent knowledge. In order to develop exhibitions that encourage visitors to process information in a differentiated way, museums need to know how visitors deal with conflicting information. Furthermore, museum professionals need information on personal and situational factors that may promote the processing of such information. We tested whether conflict processing is influenced by personal characteristics such as situational interest, epistemological beliefs, tolerance of ambiguity, and self-efficacy on the one hand and by situational conditions such as the spatial arrangement of information on the other hand. In two science museums and one museum of cultural history, text pairs were displayed that described a topic from conflicting perspectives. The spatial distance between the two texts was manipulated. Semi-structured interviews and questionnaires captured the personal characteristics of 323 visitors and the way they dealt with conflicting information. The results showed that a majority of the visitors perceived a conflict, and a large proportion was willing to process the information at a deeper level. Sophisticated epistemological beliefs, a high tolerance of ambiguity, and high self-efficacy were found to promote situational interest in conflicting information. High situational interest, in turn, promoted a tendency to process deeply. Placing text pairs in close proximity had a positive effect on the processing depth in science museums but not in the museum of cultural history. A possible explanation lies in the higher density of additional and potentially interfering information in the science museums compared to the museum of cultural history.     

Over reported and misunderstood? A study of teachers’ reported enactment and knowledge of inquiry-based science teaching

Science education reforms worldwide call on teachers to engage students in investigative approaches to instruction, like inquiry. Studies of teacher self-reported enactment indicate that inquiry is used frequently in the classroom, suggesting a high level of proficiency with inquiry that would be amenable to inquiry reform. However, it is unclear whether the high frequency of self-report is based on sound knowledge inquiry. In the absence of sound knowledge, high rates of self-reported enactment would be suspect. We conducted a study to measure teachers’ knowledge of inquiry as it related to the known, high frequency of reported enactment. We developed a multidimensional survey instrument using US reform documents and administered it to 149 K–12 teachers at a national science teachers’ conference. The majority of the teachers surveyed did not report inquiry enactment based on well-structured knowledge of inquiry. Interviews with participants showed how teachers could readily map non-inquiry activities onto inquiry statements taken directly from reform documents. From these results we argue that teachers often believed they were enacting inquiry, when likely they were not. We further reason that teachers may struggle to interpret and enact inquiry-related requirements of science education reform and will need support distinguishing inquiry from non-inquiry practices.     

Felder and Silverman's Index of Learning Styles and Honey and Mumford's Learning Styles Questionnaire: How do they compare and do they predict academic performance?

Samples of engineering and business students at undergraduate, postgraduate and post-experience levels at two UK universities completed the Index of Learning Styles (ILS) (N = 284) or the (Learning Styles Questionnaire LSQ) (N = 182) and a biographical data questionnaire. Broad psychological aspects of the two learning style instruments are examined and compared. Psychometric properties of the instruments, including factor structure, internal reliability and inter-scale correlation are analysed. Potential limitations are commented on, in particular those related to the construct validity and relatively low internal reliability of the ILS scales (alpha = 0.41 to 0.65). These compare with alphas of 0.59 to 0.74 for the LSQ. Relationships between the scales are discussed and a circumplex arrangement of the LSQ is proposed. Proposals for augmenting the circumplex are made. Academic performance results and scores on each of the two instruments are compared. The general lack of significant correlations between learning style scores and performance in these samples is discussed. Conclusions are drawn about the disappointing psychometric robustness of the measures, the activity-centred nature of learning styles and the advantages of viewing styles as a circumplex.     

What matters to supervisors and is this reflected in what they do? Analysing the work of university supervisors of the practicum

This study analyses the contemporary work and potential contribution of university supervisors supporting preservice teachers´ during their practicum experiences in initial English language teacher preparation. The study draws on a complex data derived from surveys, interviews, and observations of university supervisors working in a diverse array of English language teacher education programmes across Chile. A cultural historical activity theory perspective is employed to explore and analyse the motives, activities, and actions that underpinned the work of these supervisors. Findings suggest that supervisors have to respond to often contradictory demands and an overemphasis towards quality assurance actions that are potentially detrimental to preservice teachers´ development. The work of supervisors is analysed to understand how potentially to re-envision their role and functions, toward proposing how to productive expand supervisory practices as an integral part of teacher education.     

“So, where do they fit in?” Teachers’ perspectives of multi-cultural education and diversity in Singapore

This qualitative study attends to six Singaporean teachers’ experiences of diversity and understanding of multicultural education to illuminate the influence of national policies and narratives on teachers’ perceptions and practice. These cases illustrate that, beyond reflection on identity and diversity, there is a need for teachers to examine how political, cultural, and economic principles have shaped their understanding of diversity and multicultural education. The authors discuss findings in light of socio-political constraints faced by Singapore teachers and forward implications for teacher education.
