Contrast and value: Beyond the work ethic effect. A reply to Zentall (2008)

Zentall (2008) challenges Arantes and Grace’s (2008) failure to replicate Clement, Feltus, Kaiser, and Zentall (2000) by suggesting that our results may have been due to insufficient training or to subjects’ experimental histories, and that our results are actually consistent with those of Clement et al. when examined closely. On the contrary, our pigeons received more training than Clement et al.’s did, and when an overall measure of preference on test trials was calculated, independent of the effect of initiating event that we reported, there was no evidence of preference for the stimulus preceded by the greater response requirement in our data. Although there have now been two unsuccessful attempts to replicate Clement et al.’s work ethic effect, there is evidence that in some situations, the value of a stimulus, as assessed by transfer tests, varies inversely with the context of reinforcement. It is important to look for convergent results using other procedures and transfer tests, such as resistance to change, to identify the principles that determine when contrast manipulations affect value and when they do not.     

Symbolic representation in animals: Emergent stimulus relations in conditional discrimination learning

When two initially unrelated stimuli are associated with the same event (e.g., many-to-one conditional discriminations), an emergent relation can develop between those stimuli, allowing them to be interchangeable in other contexts. The source of the emergent relation appears to be a common representation of the two stimuli, and the nature of the representation may be retrospective, involving one of the initial stimuli (probably the stimulus that first enters into association). These emergent relations have been implicated in the establishment of stimulus equivalent relations. However, the failure to find strong evidence for other emergent relations thought to be involved in stimulus equivalence (Sidman, 1990; e.g., bidirectional associations, transitive relations, and functional equivalence associated with one-to-many conditional discriminations) suggests that the mechanisms underlying the emergent relations found using transfer designs following many-to-one training are different from those presumed to underlie stimulus equivalence. On the other hand, evidence for the common representation of stimuli associated with the same arbitrary event extends the nature of those representations beyond those well-established effects found when the common events are biologically important (e.g., the differential outcomes effect).     

E-books as support for emergent writing with and without adult assistance

The question posed in the current study is whether software alone is a sufficient tool for supporting young children’s emergent writing. We researched the effect of reading an electronic book (e-book) on kindergarten children’s emergent word writing with and without adult support. Ninety-six 5 to 6 years old children from low socioeconomic status (SES) families were randomly assigned to one of three groups (32 children each): (1) independently reading the e-book; (2) reading the e-book with adult support; (3) receiving the regular kindergarten program (control). Each intervention group received four e-book reading sessions. The children’s emergent literacy was assessed before and after the intervention and included letter-name recognition, phonological awareness and emergent word writing. Reading the e-book with adult assistance supported the children’s phonological awareness and emergent word writing more significantly than reading the e-book without support and more than the control group. Reading the e-book without adult support did not differ from the control group. Furthermore, the children’s initial emergent literacy level and reading the ebook with adult assistance contributed the most to the children’s emergent word writing. Educational implications are discussed.     

Delay discounting in rhesus monkeys: equivalent discounting of more and less preferred sucrose concentrations

Humans discount larger amounts of a delayed reinforcer less steeply than smaller amounts, but studies with pigeons and rats have yet to reveal such a magnitude effect, suggesting that the effect may be unique to humans. The present study examined whether the magnitude effect is observed in a species phylogenetically closer to humans, by comparing the rates at which rhesus monkeys discounted 10% and 20% concentrations of sucrose. There were no systematic differences in the rates at which the monkeys discounted the two sucrose concentrations, despite the fact that they strongly preferred the 20% concentration. Interestingly, the monkeys discounted delayed sucrose at a rate higher than was observed with delayed cocaine, and lower than was observed with delayed saccharin in previous studies (Freeman et al. Behavioural Processes, 82, 214-218, 2009; Woolverton et al. Experimental and Clinical Psychopharmacology, 15, 238-244, 2007). Taken together, these findings suggest that although both quantitative and qualitative differences can affect monkeys’ preferences between immediate reinforcers, qualitative differences between types of reinforcers (e.g., sucrose vs. cocaine) can affect monkeys’ discounting rates in a way that quantitative differences within a reinforcer (e.g., 10% vs. 20% sucrose) do not.     

Rethinking syntax: A commentary on E. Kako’s “Elements of syntax in the systems of three language-trained animals”

Kako (1999) requests new studies of linguistic continua between humans and nonhumans. I question the value of such studies and the importance of determining whether any component of language is uniquely human. I argue that training of specific constructs (e.g., closed classes) may not provide appropriate data, and that whether a particular species lacks or has human-like syntax likely results from specific ecological/evolutionary pressures. Social factors purported to drive intelligence and communication in primates likely exist for nonprimates such as parrots; moreover, Grey parrots demonstrate rudiments of supposedly uniquely human abilities: supralaryngeal vocal tract control, anticipatory coarticulation, and sound play.     

Concept mapping as a follow-up strategy to learning from texts: what characterizes good and poor mappers?

Concept maps consist of nodes that represent concepts and links that represent relationships between concepts. Various studies have shown that concept mapping fosters meaningful learning. However, little is known about the specific cognitive processes that are responsible for such mapping effects. In a thinking-aloud study, we analyzed the relations between cognitive processes during concept mapping as well as the characteristics of the concept maps that the learners produced and learning outcomes (38 university students). To test whether differences in learning outcome are due to differences in general abilities, verbal and spatial abilities were also assessed. In a cluster-analysis two types of ineffective learners were identified: ‘non-labeling mappers’ and ‘non-planning mappers’. Effective learners, in contrast, showed much effort in planning their mapping process and constructing a coherent concept map. These strategies were more evident in students with prior concept-mapping experience (‘advanced beginners’) than in those who had not used this learning strategy before (‘successful beginners’). Based on the present findings, suggestions for a direct training approach (i.e., strategy training with worked-out examples) and an indirect training approach (i.e., supporting the learners with strategy prompts) were developed.     

Making the most of the mosaic: facilitating post-school transitions to higher education of disadvantaged students

Research studies of post-school education and training conducted in Australia and internationally have revealed a mosaic of students’ education and employment experiences, with a multiplicity of nonlinear pathways. These tend to be more fragmentary for disadvantaged students, especially those of low socio-economic background, rural students, and mature aged students seeking a ‘second chance’ education. Challenges faced by students in their transitions to higher education are made more complex because of the intersection of vertical stratification created by institutional and sectoral status hierarchies and segmentation, especially relating to ‘academic’ and ‘vocational’ education and training, and the horizontal stratification of regional, rural and remote locations in which students live. If we are to achieve the equity goals set by the Bradley Review (Bradley et al., Review of Australian Higher Education Final Report, 2008) we need to acknowledge and work with the complex realities of disadvantaged students’ situations, starting at the school level. Interrelated factors at the individual, community and institutional level which continue to inhibit student take-up of higher education places are discussed in the context of discursive constructions of ‘disadvantage’ and ‘choice’ in late modernity. Research highlights the need to facilitate students’ post-school transitions by developing student resilience, institutional responsiveness and policy reflexivity through transformative education.     

Criteria for assessing quality in academic research: the views of biomedical scientists, clinical scientists and social scientists

This study empirically addresses the claim made by Gibbons et al (The new production of knowledge: The dynamics of science and research in contemporary societies. Sage, Thousand Oaks, 1994) that a novel form of quality control (associated with Mode 2 knowledge production) is supplementing the “traditional” peer-review process (associated with Mode 1 knowledge production). A qualitative design was used to explore faculty members’ views on the criteria for assessing scientific research. Ninety-four semi-structured interviews were conducted with biomedical scientists, clinical scientists, and social scientists working in Canadian universities. Results show that the vast majority of participants are aligned with the “traditional” Mode 1 peer-reviewed procedures for assessing research and defining scientific excellence. These participants asserted that peer review is the best quality control mechanism for assessing scientific research, and peer recognition the key attribute for legitimacy in the academic arena. In contrast, participants ascribed a low value to non-academics’ judgment of their work. While the study findings do not provide support Gibbons et al.’s claim, they add to a growing body of evidence that supports the continuing importance of peer review in academic career success.     

Stimulus control of anticipatory responding in instrumental learning as revealed in serial learning tasks

Items in a fixed series A-B-C can be anticipated employing either item information (e.g., ItemA cues signal Item B) or position information (e.g., Position 2 cues signal Item B). Identical fixed series of rewarded and nonrewarded trials were employed in investigations reported by Capaldi and Miller (1988), Capaldi, Alptekin, Miller, and Birmingham (1997), and Burns, Dunkman, and Detloff (1999). These series were learned employing item cues according to Capaldi and colleagues and position cues according to Burns et al. (1999). Burns et al.’s (1999) conclusions were based on rats’ behavior when shifted to novel series, which could reveal position learning but not item learning. Employing the acquisition conditions of Burns and co-workers but shifts to series that could reveal item learning, evidence for item learning was obtained in two experiments. The most reasonable interpretation of the above set of findings is that rats employ a compound of both types of cues to signal items. To our knowledge, no set of prior findings so strongly suggests a similar conclusion.     

Books and Good Stuff: A Strategy for Building School to Home Literacy Connections

Engaging young children in literacy activities at home is one way for families to augment and enrich the home literacy setting and to participate in their child’s education at an early age (St. Pierre et al. in Dev Psychol 41(6): 953–970, 2005). Burgess et al. (Read Res Quart 4(4): 408–426, 2002) suggested that the resources families have at their disposal, the quality of literacy role models provided by parents, and the types of literacy and language activities in which parents and children engage, are all related to young children’s developing literacy and language abilities. Other studies demonstrated that even modest literacy-promoting interventions can significantly enhance a young child’s early literacy environment by increasing the frequency of parent–child book-sharing activities (Weitzman et al. in Pediatrics 113(5):1248–1253, 2004). Dever (J Early Educ Fam Rev 8(4):17–28, 2001) and Dever and Burtis (Early Child Dev Care 172(4):359–370, 2002) emphasize the use of family literacy bags for early childhood development. Developing and sharing take-home literacy bags is an exciting literacy-promoting activity that may be shared with children and families to provide support for emergent literacy. This article explores the development of the BAGS (Books and Good Stuff) take-home literacy kits and provides suggestions for content, construction, implementation, and evaluation. Sixteen current books are reviewed and recommended by theme.     

What ‘ideas-about-science’ should be taught in school science? A chemistry teachers’ perspective

The objective of this study is to facilitate in-service chemistry teachers’ understanding of nature of science and what ‘ideas-about-science’ can be included in the classroom. The study is based on 17 in-service teachers who had registered for a 11-week course on ‘Epistemology of Science Teaching’ as part of their Master’s degree program. The course is based on 17 readings drawing on nature of science and its critical evaluation. Course activities included written reports, classroom discussions based on participants’ presentations and written exams. Based on the results obtained this study has the following educational implications: (a) Experimental data need to be interpreted carefully due to underdetermination of theories by data; (b) Kuhn’s normal science manifests itself in the science curriculum through the scientific method and wields considerable influence; (c) Trilemma posed by Collins (Stud Sci Educ 35:169–173, 2000), viz., creation of new knowledge ⇔ Kuhn’s normal science ⇔ teaching nature of science, provided a big challenge and was thought provoking; (d) Of the different aspects of nature of science suggested by experts, these teachers endorsed the following as most important: Creativity, Historical development of scientific knowledge, Diversity of scientific thinking and Scientific method and critical testing; (e) With respect to the contradiction between the positions of Lederman et al. (J Res Sci Teach 39:497–521, 2002) and Osborne et al. (J Res Sci Teach 40:692–720, 2003), few supported the position of latter, viz., inclusion of scientific method in the classroom and a majority supported the former, viz., scientific method as a myth; and (f) Participants were critical of the present stage of research with respect to the scientific method and suggested the introduction of history, philosophy and epistemology of science to counteract its influence.     

The Force Concept Inventory as a Measure of Students Conceptual Coherence

The Force Concept Inventory (FCI) is a multiple choice test designed to monitor students’ understanding of the conceptual domain of force and related kinematics (Hestenes et al. Physics Teacher 30:141–158 1992; Halloun et al., 1995, Online at http://modeling.asu.edu/R&E/Research.html). It has gained wide popularity among both researchers and physics instructors in the United States and elsewhere. The FCI has also been criticized, and its validity as a measure of the coherence of a student’s understanding of the force concept has been questioned. In this paper we provide a characterization of students’ conceptual coherence and a way to evaluate it using the FCI. We divide students’ conceptual coherence into three aspects: representational coherence (the ability to use multiple representations and move between them), contextual coherence (the ability to apply a concept across a variety of contexts), and conceptual framework coherence (the ability to fit related concepts together, i.e. to integrate and differentiate between them). Postinstruction FCI results and interview data from two Finnish high school groups (n=49 total) are discussed; the data provide evidence that the FCI can be used to evaluate students’ conceptual coherence—especially contextual coherence—of the force concept.     

Evaluating the logic of perspective-taking experiments

In their recent study, Udell, Dorey, and Wynne (in press)[COMP: Ref. is LBE0034. Will have to be updated to (2011) here and in LBE0038, once page nos. are available.] showed that in a begging task, at least in some conditions, dogs as well as wolves preferentially approached a human partner who could see them in contrast to one whose eyes were occluded, and Udell et al. concluded that this success was dependent on the subjects’ experiences with the specific occluder used. Here we argue, however, that since both partners expressed similar attentiveness towards the subjects by calling their names, Udell and colleagues’ conclusion does not refer to the sensitivity of canines to others’ attentiveness, but instead reflects the fact that the animals obeyed a familiar command better in a familiar context than in an unfamiliar one. Moreover, in contrast to Udell et al.’s conclusion, we believe that their data demonstrate that pet dogs can generalize the use of the visibility of human eyes to novel situations, showing a preference towards an attentive partner even if the eyes of the other partner are occluded in a novel way (e.g., having a bucket on his or her head). Finally, after presenting alternative interpretations of the results of the wolves tested by Udell and colleagues, we conclude that there is no evidence that wolves are sensitive to the attentional states of humans.     

Looking from a CHAT-IT perspective to undergraduate Mexican physics: organizational trajectories or professors as agents of change?

Recent elaborations on cultural-historical activity theory (CHAT) (Engestr?m et al., eds., Perspectives on activity theory. New York: Cambridge University Press, 1999) and its relation to organizational theories have produced a theoretical amalgam of these earlier ideas, which allow for the exploration of learning in formal organizational contexts such as schools. In this paper I reflect on Candela’s work situated in undergraduate Mexican physics by drawing attention to the CHAT-IT framework (Ogawa et al., Educational Researcher 37(2):83–95, 2008) as a viable lens. I suggest that it is important to understand the historical development of the Mexican university as an educational organization as well as the role of physics professors as agents of change whose practices contribute to not only breaking classroom walls but also to transforming the organization affecting future activity systems.     

Undisciplining Knowledge Production: Development Driven Higher Education in South Africa

South African higher education institutions are increasingly under scrutiny to produce knowledge that is more relevant to South Africa’s social and economic needs, more representative of the diversity of its knowledge producers, and more inclusive of the variety of the sites where knowledge is produced. Only a small percentage of South Africans are graduates of universities or technology institutes, and these graduates are not representative of the diversity of the South African population. As a result there is a shortage of skills to address the country’s reconstruction and developmental needs. This places a burden on higher education institutions to expand access to their programmes, and to ensure that their programmes are relevant to the developmental context. Policy makers have found in the Gibbons [Gibbons, M., et al. (1994). The New Production of Knowledge. The Dynamics of Science and Research in Contemporary Societies. London Sage Publishers] thesis on ‘Mode 2 knowledge production’ a rationale for the transformation of higher education through the inclusion of practices which are less abstract, less discipline bound and closer to those processes which characterise the diversity and distribution of knowledge production in the wider society. Nowotny et al. [Nowtony et al. (2001). Re-thinking Science. Knowledge and the Public in an Age of Uncertainty. Cambridge: Polity Press.] have taken Gibbons’ thesis further and have described society itself as becoming increasingly ‘Mode 2’. In a Mode 2 society, differentiation is replaced with integration, and networks of knowledge producers conduct their work in transdisciplinary teams across widely distributed sites. Such ‘transgressivity’ both pushes knowledge production systems forward and distributes and diffuses knowledge more widely throughout society. In this paper, it is argued that there is a need for higher education practitioners to engage critically – and constructively – with the knowledge bases of policy directives to ensure that the new teaching and learning processes and systems adequately prepare students for the complexity and diversity of South African society, and enable them to contribute meaningfully to its reconstruction and development.     

Failure to obtain value enhancement by within-trial contrast in simultaneous and successive discriminations

The present research tested the generality of the “work ethic“ effect described by Clement, Feltus, Kaiser, and Zentall (2000). In Experiment 1, we trained 10 pigeons on a pair of either simultaneous or successive discriminations. One discrimination followed a high-effort requirement (20 pecks to the center key) and the other followed a low-effort requirement (1 peck). Contrary to Clement et al.’s results, we found that preferences between the S⁺ and S⁻ stimuli in transfer tests depended on the event that initiated the trial: Pigeons preferred the stimulus from the baseline discrimination whose initiating event was most dissimilar from that preceding the test trial. Preferences were similar but less extreme in the successive condition. In Experiment 2, we investigated whether test preferences depended on the amount of training. A total of 12 pigeons were trained on a pair of simultaneous discriminations, except that test sessions were scheduled after every three baseline sessions. Preferences increased across test sessions but were similar to those in Experiment 1. Together with Vasconcelos, Urcuioli, and Lionello-DeNolf (2007a), our study represents a second failure to replicate Clement et al.’s work ethic effect. The finding that preference depends on the event that initiates the test trial suggests that choice probes may not provide unambiguous assessments of stimulus value.     

The crisis discourse of a wicked policy problem: vocational skills training in Australia

In 2007 the Rudd Labor government in Australia introduced significant changes to education policy for the nation. The Skilling Australia’s Future (Rudd et al. Skilling Australia for the future. Election 2007 policy document, 2007) policy was meant to redress a perceived failure by the previous Howard federal Liberal-National Coalition governments to fund and manage vocational skills training adequately. The Skilling Australia’s Future policy established a number of areas for immediate action. This paper looks at one of these areas from the policy document, namely, the Rudd government’s plan for addressing skills shortages (Rudd et al. 2007, pp. 4–9) through the establishment of Trade Training Centres in schools. The policy is analysed using Critical Discourse Analysis, featuring the semiotic concept of intertextuality. Findings from the application of this method suggest that Skilling Australia’s Future (2007) belongs within a history of like-minded policy and, although a new direction is provided by the allocation of Trade Training Centres to selected high schools, the policy is not clearly separable from the market-driven discourse that has pervaded education policy since the 1990s.     

Drawing on a Theoretical Model to Study Students’ Understandings of Fractions

Teaching and learning fractions has traditionally been one of the most problematic areas in primary school mathematics. Several studies have suggested that one of the main factors contributing to this complexity is that fractions comprise a multifaceted notion encompassing five interrelated subconstructs (i.e., part-whole, ratio, operator, quotient, and measure). Kieren was the first to establish that the concept of fractions is not a single construct, but consists of several interrelated subconstructs. Later on, in the early 1980s, Behr et al. built on Kieren’s conceptualization and suggested a theoretical model linking the five subconstructs of fractions to the operations of fractions, fraction equivalence, and problem solving. In the present study we used this theoretical model as a reference point to investigate students’ constructions of the different subconstructs of fractions. In particular, using structural equation modeling techniques to analyze data of 646 fifth and sixth graders’ performance on fractions, we examined the associations among the different subconstructs of fractions as well as the extent to which these subconstructs explain students’ performance on fraction operations and fraction equivalence. To a great extent, the data provided support to the associations included in the model, although, they also suggested some additional associations between the notions of the model. We discuss these findings taking into consideration the context in which the study was conducted and we provide implications for the teaching of fractions and suggestions for further research.     

French nursery schools and German kindergartens: effects of individual and contextual variables on early learning

The present article investigates the effects of individual and contextual variables on children’s early learning in French nursery schools and German kindergartens. Our study of 552 children at preschools in France (299 children from French nursery schools) and Germany (253 children from German kindergartens) measured skills that facilitate the learning of reading, writing and arithmetic at primary school. We also evaluated educational family practices and parents’ expectations of their children’s pre-school education. In order to take into account the hierarchical structure of our data, multilevel models were used in the analysis, which was carried out using MLwiN software version 2.02 (Rasbash et al. 2005). Although French nursery schools emphasise academic learning, we did not find any significant differences in overall performances between the French and German samples. However, significant differences were obtained for some subscale results. In addition, our results indicate that individual and contextual variables have an impact on the differences observed between children from the two countries.     

A design study of a multimedia instructional grammar program with embedded tracking

This is a design study meant to demonstrate the feasibility of integrating three rather different theoretical perspectives for future efforts in multimedia instructional design. A multimedia instructional grammar program contextualized within the teaching of English as a Second Language (ESL) was developed and evaluated. The program design was grounded in Mayer’s multimedia learning theory (2001), Sweller’s cognitive load theory (CLT, 2005), and cognitive training theory using an inductive reasoning paradigm (Klauer and Phye, Rev Educ Res 78(1):85–124, 2008). A successful integration of cognitive training theory into program design is expected to facilitate the transition of student’s declarative knowledge of a grammar concept of passive voice to procedural knowledge (Phye, Contemp Educ Psychol 16:87–94, 1991; Phye et al., Empirical methods for evaluating educational interventions, Academic Press/Elsevier, San Diego, 2005). Two studies involving ten and four adult ESL learners were conducted in a Midwest community college. Grammar teaching occurred within the context of history and geography of the USA. Students with low prior knowledge of passive voice grammar concepts, intermediate level of general vocabulary, and adequate basic knowledge of content (basic geography and history) benefited most from the program. Preliminary results are encouraging for the aforementioned integrative efforts.
