Experimentation in biology lessons: guided discovery through incremental scaffolds

Experimentation is a complex problem-solving process. In biology lessons, experiments involve creative thinking and open discovery; however, they still require some degree of instructional guidance. The right balance between discovery learning and instructional guidance depends substantially on students’ prior knowledge. Students with low prior knowledge in particular might have difficulties with conducting and understanding experiments. Incremental scaffolds might be a valuable tool to meditate between pure discovery and strong guidance while simultaneously taking learners’ individual knowledge and skills into account. In the current study, we examined the effects of incremental scaffolds (IncSc), no scaffolds (NoSc), and worked-out examples (WoEx) on students’ knowledge acquisition while doing inquiry-based experimentation with a special focus on students with low prior knowledge. In a pre-posttest design, 193 students (M_age?=?13.02?±?0.81 years) participated in a four-hour teaching unit on animals’ overwintering strategies. In the pre- and posttest, we assessed the students’ conceptual and procedural knowledge. Our results partially confirmed our hypotheses: Regarding the conceptual and procedural knowledge of all students, incremental scaffolds showed no additional benefit regarding students’ knowledge in the posttest when compared to working with no scaffolds or worked-out examples. For the students with low prior knowledge, working with incremental scaffolds led to higher conceptual and procedural knowledge after the teaching unit than working with worked-out examples.     

Strategic and bonding effects of enhancing the student feedback process

In order to produce distinctiveness that leads to competitive advantage, higher education institutions must remain cognizant that students are co-creators. Thus, to create genuine value in educational service delivery, there is a need for a more highly developed understanding of the student-institutional intersection. The present research contributes to the marketing of higher education by developing and testing a model related to the antecedents of a broader conception of student feedback as part of student/customer orientation and co-creation. Conceived as customer feedback, student feedback to an educational institution can be positive (compliment), negative (complaint), or be an idea for an improvement to any person, or service group of the institution. Perceived ease of the feedback process and perceived usefulness, customer orientation and affective commitment are found as antecedents to intention to provide feedback. The result is a model with conceptual and managerial implications for strategically bonding students to universities.     

The changing discourse on race in contemporary Cuba

During the last decade, the positivist perspective of social reality has lost credibility in education and other fields, giving way to a wide range of alternative conceptions of social science. This proliferation is welcome but confusing. This paper examines several intellectual traditions within the “post‐positivist camp” and identifies a number of approaches to decoding social reality as guidelines for field‐based research.     

Popularizing the ancestry of man: Robert Ardrey and the killer instinct

This essay examines Robert Ardrey (1908-1980)-American playwright, screenwriter, and prolific author-as a case study in the popularization of science. Bringing together evidence from both paleoanthropology and ethology, Ardrey became in the 1960s a vocal proponent of the theory that human beings are innately violent. The essay shows that Ardrey used his popular scientific books not only to consolidate a new science of human nature but also to question the popularizer's standard role, to reverse conventional hierarchies of scientific expertise, and to test the boundaries of professional scientific authority. Understanding how he did this can help us reassess the meanings and uses of popular science as critique in Cold War America. The essay also shows that E. O. Wilson's sociobiology was in part a reaction to the subversive political message of Ardrey's science.     

Hiding in plain sight: Paratextual utterances as tools for information-related research and practice

Through a qualitative content analysis of a purposive sample (the 2010 finalists of the Canadian Governor General's Literary Awards in both French and English), this study investigates what information can be gleaned from the book-as-object using peritext as a research tool. Using the theories of Gérard Genette, who defined the paratext, and Pierre Bourdieu, this research posits that paratextual utterances serve as an expression and tool of the cultural realm of publication and can be used for informational purposes in library and information science (LIS) research and practice. Findings indicate that the peritext is a rich source for gathering information about authorship and publishing as it reveals contextually relevant information, shares the author's informational tools, constructs the author, markets titles, and provides relevant information for specific age groups and genres. Discussion centers on the impact for libraries and the LIS community, with a focus on readers' advisory.

Validity and reliability of portfolio assessment in pre‐service teacher education

This article concentrates on the validity and reliability of portfolio assessment as used in pre‐service teacher education. It is not possible to make general pronouncements about the validity of portfolio assessment in pre‐service teacher education as there are multiple portfolio applications. The validity depends on the purpose, namely the divers competencies which the course organisers wish to assess with it. Therefore, three categories of competencies and consequently three types of portfolios were distinguished in order to determine the validity of portfolio assessment. For the assessment of teaching and partnership competencies, it is argued that the validity is low due to the roundabout nature of the assessment. On the contrary, the validity of portfolio assessment for learning competencies can be high. The execution of a self‐regulated learning process can be accurately assessed using portfolios. The reliability of portfolio assessment is problematic, since it is incapable of fulfilling the classic psychometric requirement of reliability. Nevertheless, provided that the necessary measures are taken, the reliability of portfolio assessment can still be brought to an acceptable level. Five measures are proposed.     

The impact of the French policy mix on business R&D: How geography matters

Based on a spatial extension of an R&D investment model, this paper measures the macroeconomic impact of the French R&D policy mix on business R&D using regional data. Our measure takes into account not only the direct effect of policies but also indirect effects generated by the existence of spatial interaction between regions. Using a unique database containing information on the levels of various R&D policy instruments received by firms in French NUTS3 regions over the period 2001–2011, our estimates of a spatial Durbin model with structural breaks and fixed effects reveal the existence of a negative spatial dependence among R&D investments in regions. In this context, while a-spatial estimates would conclude that all instruments have a crowding-in effect, we show that national subsidies are the only instrument that is able to generate significant crowding-in effects. On the contrary, it seems that the design, size and spatial allocation of funds from the other instruments (tax credits, local subsidies, European subsidies) lead them to act (in the French context) as beggar-thy-neighbor policies.     

Assessing pupils’ intelligence through self,parental, and teacher estimates

This study examined the accuracy of self‐ and other‐estimated intelligence in relation to tested cognitive ability and gender. Three groups of raters were examined: 187 (102 male, 85 female; mean age 14.33 years, SD = .32) pupils of single‐sex comprehensive schools, 109 (55 mothers and 54 fathers) parents, and six teachers of the pupils. Pupils estimated their own overall IQ, while their parents and teachers estimated the pupils’ overall, mathematical, spatial, and verbal abilities. Self‐ and other‐estimates were compared to each other, and to the child’s psychometric test scores in verbal, quantitative, and figural/non‐verbal reasoning ability. Results suggested that participants were reasonably accurate at estimating pupils’ intelligence – teachers significantly more so than parents, and pupils significantly more so than fathers. Although both parents significantly overestimated their child’s IQ, this overestimation was more pronounced in fathers.
