Drawing a computer scientist: stereotypical representations or lack of awareness?

ABSTRACT

Stereotypes people hold about computer scientists contribute to underrepresentation in computer science. Perceptions of computer scientists have historically been linked to males and a “nerd” culture, which can lead to lack of interest, particularly for girls. This article presents two studies conducted with two groups of middle schoolers: those who attended our programming camp (Study One) and those who did not (Study Two). After analyzing participants’ drawings and two survey questions we found that perceptions youth holds about computer scientists may be improving. Additionally, we found that males (versus females) and those youth who did not attend our camp (versus those who did) tended to have more stereotypical perceptions of computer scientists. With this article, we contribute to the literature on CS stereotypes by examining both positive and negative representations youth had about computer scientists. We also cast light on the lack of awareness about this profession among the youth of this age.     

Receptive sign vocabulary tests: tests of single-word vocabulary or iconicity?

First-, fourth-, and ninth-grade hearing students were administered randomly selected items from the Carolina Picture Vocabulary Test (CPVT; Layton & Holmes, 1985) to determine the degree to which signs used in the CPVT are iconic (see note) and can actually convey a sign's meaning at the moment of testing, thus providing an inflated vocabulary score. Hearing students were tested because they had no prior sign knowledge or experience. Results indicate that the signs used in the CPVT are sufficiently iconic to enable students unfamiliar with signs to identify a test picture; 73% of their responses were correct when chance selection was 25%. Such findings signal potential problems with existing receptive sign vocabulary tests; consequently, test results should be interpreted cautiously. Note: Not all signs are iconic. Iconic signs have semantic features nested in their formation, location, and movement that visually convey enough information to manifest word meaning. Formation, location, and movement are also called cheremic features of sign.     

Teacher Professional Standards: Controlling or developing teaching?

The issue of professional teaching standards has generated considerable interest from various quarters in Australia and elsewhere. In this paper, I am concerned with examining some of the claims made by advocates for the establishing of uniform standards for the teaching profession. To this end I identify three major claims derived from the Australian literature regarding the benefits that the application of a standards framework would make to the quality of teaching: the introduction of standards should improve the performance of teachers; the introduction of standards will improve the standing of teachers; and standards contribute to the on-going professional learning of teachers. Specifically, I argue that we need to look critically at the issue of professional standards for teachers and the claims that are made by their advocates. In particular, we need to ask whose interests are served by these standards and what are the effects of the imposition of these standards on teachers individually and collectively. Finally, we need to ask whether the standards judged as appropriate for today's teaching conditions and teachers will be equally appropriate in the future. Standards cannot and should not be frozen in time; they must be flexible to the changing conditions of teaching and learning as they occur inside and outside of schools.     

Leaving or staying in teaching: a ‘vignette’ of an experienced urban teacher ‘leaver’ of a London primary school

In the field of teacher attrition, there is a significant body of literature on why teachers leave high-needs urban schools and particularly why beginning teachers leave their schools and the profession. However, there is little research on the reasons why experienced teachers leave the teaching profession. This paper examines this subject by considering whether teachers experience an ‘identity crisis’ in their careers which prompts them to leave. Drawing on identity theory, data from a single case study of an experienced urban teacher are taken from a wider qualitative research study carried out in London, England. The case is made that decisions to leave or stay in a school are contingent on a number of personal, professional and situational factors related to the teacher’s identity. The article concludes that one way to understand why long-serving teachers leave the profession is to examine aspects of their teacher identity and explore how a crisis in professional identity can contribute towards teacher attrition. In the light of this alternative approach towards understanding attrition, at the very least, supportive structures can be put in place to encourage more teachers to stay and contribute to the success and well-being of children from disadvantaged backgrounds.     

More or better student teaching?

Drawing from data on over 1000 prospective teachers in a large urban district including pre and post-student teaching survey data, this study investigates whether lengthening student teaching improves teachers’ perceptions of instructional preparedness, efficacy, and career plans. The findings suggest that the duration of student teaching has little effect on teacher outcomes; however, the quality of student teaching has significant and positive effects. Moreover, the magnitude of the effects of student teaching quality are greater when student teaching is shorter and in schools with more historically underserved racial groups. The authors discuss policy implications and directions for further research.     

Risk or resilience? What makes a difference?

Dropping out of school has been associated with a student’s ethnicity, socioeconomic status, challenging behaviours and low academic achievement. This paper describes research conducted with 1050 students aged 12–15, in three North Queensland urban high schools to investigate issues related to Indigenous and non-Indigenous students at risk of dropping out of school before gaining adequate qualifications.     

Does evaluation of teaching lead to improvement of teaching?

Abstract

Given the widespread use of student evaluation of teaching in North American colleges and universities, it is reasonable to ask whether student evaluation has accomplished one of its major intended outcomes, namely improvement of instructional quality. A review of research evidence from three independent sources (faculty surveys, field experiments and longitudinal comparisons) suggests that student evaluation does in fact contribute significantly to improvement of certain aspects of university teaching, particularly if evaluation is supplemented by expert consultation. Furthermore, there is no clear evidence that student evaluation has led to undesirable instructional side‐effects, such as grade inflation and entrenchment of traditional teaching methods.     

Big brother or harbinger of best practice: Can lecture capture actually improve teaching?

Lecture capture is used increasingly in the UK, and has become a normal feature of higher education. Most studies on the impact of lecture capture have focused on benefits to student learning, the flipped classroom or student non‐attendance at lectures following its introduction. It is less clear how the use of lecture capture has impacted on lecturers’ own academic practice. In this study, we use a mixed‐methods approach to explore the impact of this intrusive yet invisible technology on the quality of teaching. We have mapped our findings to the UK Professional Standards Framework (UKPSF). In doing so, our data paints a mixed picture of lecture capture's Janus‐faced reality. On the one hand, it enhances lecturer self‐awareness, planning and conscious ‘performance’; on the other hand, it crushes spontaneity, impairs interaction and breeds wariness through constant surveillance. While the Teaching Excellence Framework rewards institutions for providing state‐of‐the‐art technology and lecture recording systems, our findings pose awkward questions as to whether lecture capture is making teaching more bland and instrumental, albeit neatly aligned to dimensions of the UKPSF. We provide contradictory evidence about lecture capture technology, embraced by students, yet tentatively adopted by most academics. The implications of our study are not straightforward, except to proceed with caution, valuing the benefits but ensuring that learning is not dehumanised through blind acceptance at the moment we press the record button.     

Beliefs about teaching: Persistent or malleable? A longitudinal study of prospective student teachers' beliefs

This longitudinal study focused on change in university students' beliefs about the role of teachers. The students (n = 80) were Estonian undergraduates, whose beliefs were investigated in the first and third years of their studies and followed up to the point at which the students either entered teacher education or chose other paths. Beliefs about teaching were neither unambiguously persistent nor malleable. Students who continued in teacher education exhibited stronger beliefs about the teacher as pedagogue and aligned less with the belief that the teacher's role is to be a subject matter expert than peers who did not choose teacher education.     

Interactive or inactive? a consideration of the nature of interaction in whole class teaching

Recent learning theories and the suggested importance of ‘interactive’ approaches in national initiatives, (NLS, NNS) led to an ESRC‐funded action research project involving the University of Exeter and teachers in three schools—‘Using Talk to Activate Learners’ Knowledge' (TALK). This investigated how ‘interactive’ whole class teaching was and whether teacher‐pupil interactions permitted recoding of information and understanding. The findings corroborate those from Galton (1999 Galton M Hargreaves L Comber C Wall D Pell T (1999a) Inside the primary classroom—20 years on (London, Routledge) [Crossref] [Google Scholar]a, 1999 Galton, M, Hargreaves, L, Comber, C, Wall, D and Pell, T. (1999b). Changes in patterns of teacher interaction in primary classrooms: 1976–1996. British Educational Research Journal, 25(1): 23–37. [Taylor & Francis Online] [Google Scholar]b), Mroz (2000 Mroz, M, Smith, F and Hardman, F. (2000). The discourse of the Literacy Hour. Cambridge Journal of Education, 30(3): 379–390. [Taylor & Francis Online] [Google Scholar]) and English (2002 English, E, Hargreaves, L and Hislam, J. (2002). Pedagogical dilemmas in the National Literacy Strategy: primary teachers' perceptions, reflections and classroom behaviour. Cambridge Journal of Education, 32(1): 9–26. [Taylor & Francis Online] [Google Scholar]): that teacher‐led questioning and explanation still dominate, as do teachers' objectives. Interaction as participation was differentially experienced by higher and lower abilities, boys and girls, with few opportunities for pupil initiation or extended response. The study, however, provides a model for more fully analysing the varying forms and functions of teachers' questions and statements which may lead to a greater clarity in recognising ways to provide more effective discourse for learning.     

Contents or ideology? A case study of mathematical teaching in North Korea

This article addresses mathematics education in one of the most closed countries in the world, North Korea. It is known that ideology permeates all aspects of life in North Korea, but how exactly do the ideological and substantive mathematical components interact in mathematics education there? What concrete form does this interaction take in actual everyday teaching practice? This article seeks to answer these questions based on interviews with former North Korean mathematics teachers and students who have found a refuge in South Korea. With their help, we attempt to analyze the everyday life of North Korean schools, by reconstructing their concrete features and the routines of North Korean mathematics education.     

The role of the teaching headteacher: A question of support?

This article reports findings from a study of 100 headteachers of very small Scottish primary schools. The main aim of the research was to follow up a sample of those schools that had participated in a larger study of all small schools in Scotland in 1996 to explore the role of the teaching headteacher. Evidence for this follow up study was collected from a postal survey and from interviews in nine case study schools. The research found that although the dual role of the teaching headteacher remained largely unchanged, pressures have increased while the available support is still perceived to be inadequate.     

Once good teaching,always good teaching? The differential stability of student perceptions of teaching quality

In many countries, students are asked about their perceptions of teaching in order to make decisions about the further development of teaching practices on the basis of this feedback. The stability of this measurement of teaching quality is a prerequisite for the ability to generalize the results to other teaching situations. The present study aims to expand the extant empirical body of knowledge on the effects of situational factors on the stability of students’ perceptions of teaching quality. Therefore, we investigate whether the degree of stability is moderated by three situational factors: time between assessments, subjects taught by teachers, and students’ grade levels. To this end, we analyzed data from a web-based student feedback system. The study involved 497 teachers, each of whom conducted two student surveys. We examined the differential stability of student perceptions of 16 teaching constructs that were operationalized as latent correlations between aggregated student perceptions of the same teacher’s teaching. Testing metric invariance indicated that student ratings provided measures of teaching constructs that were invariant across time, subjects, and grade levels. Stability was moderated to some extent by grade level but not by subjects taught nor time spacing between surveys. The results provide evidence of the extent to which situational factors may affect the stability of student perceptions of teaching constructs. The generalizability of the students’ feedback results to other teaching situations is discussed.     

Is distance teaching more work or less work?

Abstract

This article presents data collected in a year‐long study in which the author and his assistants kept detailed records of their time spent teaching and maintaining two comparable university courses. One course was offered online to adult professionals away from campus, the other offered to undergraduates in traditional classrooms on campus. The courses had similar learning objectives, similar student activities, and equally favorable ratings by students. Both were mature courses that required only routine maintenance and revision. The data do not support the widely held belief that teaching an asynchronous online course requires more effort than teaching a comparable synchronous classroom course. Although the distance course required more frequent attention, the total teaching and maintenance time spent per student was less than that required to teach and maintain the classroom course. Categories of teaching tasks are also compared.     

The teaching portfolio: institutional imperative or teacher’s personal journey?

This research draws on the experiences of a group of tertiary teachers who compiled a multi‐purpose portfolio as an assessment component of a postgraduate certificate in tertiary teaching at a New Zealand University. The research was initially undertaken in response to feedback from some of the participants that the experience of compiling a portfolio generated intense emotions. The data for this study were the retrospective reflections of the tertiary teachers on the experience of creating a portfolio as well as the portfolios themselves. The authors chose a narrative research methodology as an appropriate way to investigate a process that essentially involved the storying of the participants’ achievements and identities as tertiary teachers. The findings revealed that some participants felt uncomfortable about the blend of the formative (or developmental) and summative (or evaluative) functions of the multi‐purpose portfolio and that producing the portfolio evoked a range of complex emotions. These findings have led to the reformulation of the portfolio task.     

Building consensus views or interrogating metanarratives? Musings on teaching the nature of science

This article is a response to María del Mar Aragón, José Antonio Acevedo-Díaz and Antonio García-Carmona’s article, which investigated pre-service teachers’ understandings of epistemic and non-epistemic aspects of the nature of science (NOS) based on the historical case study of Ignaz Semmelweis and childbed fever. We situate the study in contemporary mainstream debates on teaching NOS and argue that science educators ought to focus on conveying specific aspects of NOS in-depth, instead of covering a general check list of NOS tenets in their classrooms. Furthermore, we argue that there are multiple ways of narrating the story of science, the protagonist of science classrooms, and that educators should also be conscious of the metanarratives regarding science that get conveyed in their narratives.
