Improving the judgment of task difficulties: prospective teachers’ diagnostic competence in the area of functions and graphs

To teach adaptively, teachers should be able to take the students’ level of knowledge into account. Therefore, a key component of pedagogical content knowledge (PCK) is the ability to assume the students’ perspectives. However, due to the so-called expert blind spot, teachers tend to misestimate their students’ knowledge, such as when estimating the difficulty of a given task. This empirically well-documented estimation bias is predicted by Nickerson’s anchoring and adjustment model, which generally explains how people take on other people’s perspectives. In this article, we present an intervention study that aims to improve the accuracy of prospective teachers’ judgments of task difficulty in the area of functional thinking. Two types of treatments are derived from Nickerson’s model. In the first condition (PCK group), participants acquire knowledge about task characteristics and students’ misconceptions. The second condition (sensitizing group) serves to control the idea that potential improvements in the PCK group are not merely based on a pure sensitization of the expert’s estimation bias. Accordingly, these participants are only informed about the general tendency of overestimating task difficulties. The results showed that the PCK group improved both in terms of the accuracy of the estimated solution rates and the accuracy of rank order, whereas the sensitizing group only improved in regard to the former. Thus, the study shows that prospective teachers’ diagnostic judgments can be improved by teaching them relevant PCK in a short amount of time.     

Effects of memory load on word recognition: Are there dual-routers in Norway?

The release-from-competition (RFC) effect, inwhich a difficult concurrent memory task speedspronunciation of low-frequency irregular wordsbut slows pronunciation of other word types,has been interpreted as strong support for thedual-route approach to word recognition. However, attempts to replicate this effect havenot produced consistent results. Besides,attempts at replication have mostly beenlimited to skilled readers of English. Thepresent research attempted to replicate the RFCeffect with mature normal readers of Norwegianand thus tested the generalizability ofdual-route models to a considerably moreshallow orthography than English. There was noevidence that the RFC effect reliably occurredamong Norwegian readers in this study, not evenamong certain selected readers who were seen ascandidates for possessing a dual-routearchitecture and suffering within thatarchitecture the kind of competition in naminglow-frequency irregular words that RFC issupposed to eliminate. Thus, it was notpossible to extend the applicability of adual-route approach to word recognition to therelatively shallow Norwegian orthography, andthe question of the architectural organizationof Norwegian readers was essentially leftunanswered by our data.     

Attitudes of Teachers Towards Inclusive Education in Finland

ABSTRACT

Positive teacher attitudes are essential for success when children with special educational needs (SEN) are placed into mainstream classrooms. The present study surveyed teachers’ attitudes towards inclusion by using a large national sample and Teachers’ Attitudes towards Inclusion Scale (TAIS). A total of 1,764 Finnish basic-school teachers participated in the e-mail survey. They included 824 classroom teachers, 575 subject teachers and 365 special-education teachers. The classroom teachers scored below and the subject teachers significantly below, the neutral midpoint of the scale. The special-education teachers’ mean scores were above the midpoint. About 20% of teachers were strong opponents of inclusion, and 8% were strong advocates. The attitudes towards inclusion had only weak associations with variables other than the teacher category. Teachers’ work orientation and self-efficacy had low associations with their attitudes towards inclusion. The results illustrate the attitudinal climate of teachers towards inclusion and indicate the existing potential for policy change.     

Students’ qualification in environmental and sustainability education—epistemic gaps or composites of critical thinking?

In an ‘age of measurement’ where students’ qualification is a hot topic on the political agenda, it is of interest to ask what the function of qualification might implicate in relation to a complex issue as Education for Sustainable Development (ESD) and what function environmental and sustainability issues serve in science education. This paper deals with how secondary and upper secondary teachers in discussions with colleagues articulate qualification in relation to educational aims of ESD. With inspiration from discourse theory, the teachers’ articulations of qualification are analysed and put in relation to other functions of education (qualification, socialisation and subjectification). The results of this study show three discourses of qualification: scientific reasoning, awareness of complexity and to be critical. The discourse of ‘qualification as to be critical’ is articulated as a composite of differing epistemological views. In this discourse, the teachers undulate between rationalistic epistemological views and postmodern views, in a pragmatic way, to articulate a discourse of critical thinking which serves as a reflecting tool to bring about different ways of valuing issues of sustainability, which reformulates ‘matter of facts’ towards ‘matter of concerns’     

Can narrative cutscenes improve home learning from a math game? An experimental study with children

Little is known about the instructional effects of narrative framing elements in child learning games. In this study, second and third graders (M_age = 8.24) played one of two versions of a successful, commercial mathematical learning game at home for 2 weeks (N = 95; between-subject design). The versions differed in the presence/absence of a background story conveyed through comic cutscenes at the beginning and the end of the game. Results showed that children played the game intensively in both conditions: despite not being forced to do so. Plus, they also learned from the game. As expected, children assigned to the cutscenes condition interfaced with the cutscenes. However, no between-group difference was detected in pre-post learning gains, parent-reported engagement, self-reported enjoyment, time spent with the game and the number of solved in-game tasks (all |ds| < 0.29). Altogether, no advantage or disadvantage from the narrative comic cutscenes was revealed.     

Knowledge outside the box – sustainable development education in Swedish schools

Background: Sustainable development, as an area of knowledge, appears in several different places in the curriculum and does not fit neatly within the scope of traditional subject areas. In many countries, including Sweden, it has long been upheld as an important tool for increasing understanding of, and dealing with, environmental problems. It is not clear, however, what role education can actually have in the making of a more sustainable future. Even though there are several potential ways for sustainable development to be involved in education, the concept raises many questions when transferred to the school context.

Purpose: This paper investigates how teachers deal with the difficulty of defining and approaching sustainable development as an area of knowledge in Swedish schools.

Sample: This article is based on semi-structured interviews with 40 teachers, 13 of whom were lower secondary school teachers (pupil age 12–15) and 27 were upper secondary school teachers (pupil age 15–18). The study involves teachers in all subjects where sustainable development is a goal in the syllabus. The study is also based on participant observation in one upper secondary class. A total of 17 different schools were involved, from a wide range of locations in Sweden.

Design and methods: The paper builds on qualitative data and the analysis of transcribed interviews and group interviews with teachers in Swedish lower and upper secondary schools. Group interviews, involving three or more people, were conducted on eight occasions. The pupils at an upper secondary school were also observed while they were working on a course called ‘policy and sustainable development’. Data were transcribed and analysed thematically.

Findings: The analysis suggests that, according to the teachers’ experiences, the demands of equivalence and measurability in school have increased and that this affects how sustainable development is approached in teaching and learning. Three main categories of knowledge were identified. The study also presents two representations that model how teachers may approach knowledge about sustainable development – metaphorically termed ‘the Accountant’ and ‘the Adventurer’ – and their different effects on knowledge.

Conclusions: There is a tendency for complex knowledge areas such as sustainable development, which do not fit seamlessly into traditional curriculum subjects, to become oversimplified when translated into teaching situations. According to the representations that we described metaphorically, the teacher, as an accountant, is characterised by ‘knowledge instrumentalism’, which means that teachers administer knowledge and the pupils consume it. In this transactional model, the accountant is also very dependent on external governance and control. Alternatively, the teacher, as an adventurer, is characterised by authority, knowledge and self-control. In this model, knowledge sometimes grows in an unpredictable way in the meeting between people who share common experiences. For adventurers, sustainable development is a matter of commitment and awareness, and it involves an explicit stance. The metaphors can be placed on a continuum which describes how teachers manage the demands of the school system in relation to the knowledge area of sustainable development.     

Number of Subjects and Time Points Needed for Multilevel Time-Series Analysis: A Simulation Study of Dynamic Structural Equation Modeling

Dynamic structural equation modeling (DSEM) is a novel, intensive longitudinal data (ILD) analysis framework. DSEM models intraindividual changes over time on Level 1 and allows the parameters of these processes to vary across individuals on Level 2 using random effects. DSEM merges time series, structural equation, multilevel, and time-varying effects models. Despite the well-known properties of these analysis areas by themselves, it is unclear how their sample size requirements and recommendations transfer to the DSEM framework. This article presents the results of a simulation study that examines the estimation quality of univariate 2-level autoregressive models of order 1, AR(1), using Bayesian analysis in Mplus Version 8. Three features are varied in the simulations: complexity of the model, number of subjects, and number of time points per subject. Samples with many subjects and few time points are shown to perform substantially better than samples with few subjects and many time points.     

Effects of disfluency and test expectancy on learning with text

Do students learn better with texts that are Open image in new window (i.e., disfluent)? Previous research yielded discrepant findings concerning this question. To clarify these discrepancies, the present study aimed at identifying a boundary condition that determines when disfluent text is, and is not, beneficial to learning. This boundary condition is knowledge about whether a test will follow (high test expectancy) versus not (low test expectancy). Participants with high test expectancy may already engage in effortful processing, so that making text harder-to-read (disfluent) might not change their processing mode any further. Thus, particularly when no test is expected, disfluency is supposed to exert its beneficial effect. This assumption was tested in a 2?×?2 design (N?=?97) with text legibility (fluent vs. disfluent) and test expectancy (low vs. high) as factors, and learning outcomes (retention, transfer) and learning times as main dependent variables. Results revealed that high test expectancy led to better learning outcomes (for retention and transfer), but disfluent text did not. Unlike expected, there was no interaction between the two factors. Moreover, both high test expectancy and disfluency led to longer learning times, resulting in a lower efficiency when learning with disfluent compared to fluent text. Hence, the present results further question the stability and generalizability of a positive disfluency effect on learning, because only high test expectancy – but not disfluency - stimulated better learning through more effortful processing the way it was supposed to.
