The effect of the number of syllables on handwriting production

Four experiments examined whether motor programming in handwriting production can be modulated by the syllable structure of the word to be written. This study manipulated the number of syllables. The items, words and pseudo-words, had 2, 3 or 4 syllables. French adults copied them three times. We measured the latencies between the visual presentation and the first production (L1), the first and second production (L2), and the second and third production (L3). The results show an effect of the number of syllables in L1 for pseudo-words but not for words and on L2 and L3 for all the items (Experiments 1 and 2). Experiment 3 ruled out an interpretation of the latencies for pseudo-words in terms of reading time with a delayed copying task. Experiment 4 replicated the previous results and assessed the effect of varying the temporal interval between the second and third trials. The results of the four experiments confirm the role of the syllable in word writing. The number of syllables of a word modulates the time course of handwriting production.

Exemplarism in moral education: Problems with applicability and indoctrination

ABSTRACT

This article introduces an account of moral education grounded in Zagzebski’s recent Exemplarist Moral Theory and discusses two problems that have to be solved for the account to become a realistic alternative to other educational models on the market, namely the limited-applicability problem and the problem of indoctrination. The first problem raises worries about the viability of the account in ordinary circumstances. The second charges the proposed educational model with indoctrinating students. The main goal of this article is to show how an exemplar-based account of moral education can handle both problems without compromising its structure and upshot.     

Nature of Science and Science Content Learning

Besides viewing knowledge about the nature of science (NOS) as important for its own value with respect to scientific literacy, an adequate understanding of NOS is expected to improve science content learning by fostering the ability to interrelate scientific concepts and, thus, coherently acquire scientific content knowledge. However, there is a lack of systematic investigations, which clarify the relations between NOS and science content learning. In this paper, we present the results of a study, conducted to investigate how NOS understanding relates to students’ acquisition of a proper understanding of the concept of energy. A total of 82 sixth and seventh grade students received an instructional unit on energy, with 41 of them receiving generic NOS instruction beforehand. This NOS instruction, however, did not result in students having higher scores on the NOS instrument. Thus, correlational analyses were performed to investigate how students’ NOS understanding prior to the energy unit related to their learning about science content. Results show that a more adequate understanding of NOS might relate to students’ perspective on the concept of energy and might support them in understanding the nature of energy as a theoretical concept. Students with higher NOS understanding, for example, seemed to be more capable of learning how to relate the different energy forms to each other and to justify why they can be subsumed under the term of energy. Further, we found that NOS understanding may also be related to students’ approach toward energy degradation—a concept that can be difficult for students to master—while it does not seem to have a substantive impact on students’ learning gain regarding energy forms, transformation, or conservation.     

Ignis Fatuus Effect of Faculty Category: Is the Tenure Versus Non-Tenure Debate Meaningful to Students’ Course Experiences?

The American professoriate is shifting its majority makeup from tenure track to non-tenure track faculty members. Less known, though, is what the implications of this shift are for students’ course experiences. We sought to examine the extent to which the teaching practices, with regard to academic rigor and cognitively responsive teaching, differ between faculty category using observational measures of teaching in the classroom. We found that broad categorizations of faculty may not be meaningful unless they are examined in particular contexts, such as discipline and class size.     

Genetic evidence for bidirectional effects of early lexical and grammatical development

This article addresses the autonomy hypothesis of vocabulary and grammar and bootstrapping mechanisms in early language development. Two birth cohorts of 1,505 and 1,049 same-sex twin pairs from the UK were assessed at 2 and 3 years on grammar and vocabulary, using adapted versions of the MacArthur Communicative Development Inventory. Vocabulary and grammar correlate strongly at both 2 and 3 years in both cohorts. Multivariate genetic modeling reveals a consistently high genetic correlation between vocabulary and grammar at 2 and 3 years. This finding suggests the same genetic influences operate for both vocabulary and grammar, a finding incompatible with traditional autonomy hypothesis, at least in early acquisition. Crosslagged longitudinal genetic models indicate both lexical and syntactical bootstrapping operate from 2 to 3 years.     

Teacher's role and reproducibility of didactical situations

Is it possible to specify teaching situations and to control their effects on students' learning? This general question is essential regarding the scientific character of research on mathematics education. It especially concerns the teacher's role in the class: can she ensure sufficient fidelity to a predefined scenario? This question is of special importance in the case of an experimental scenario the design of which is the result of a collaboration between a researcher and a teacher. This is considered here in the context of two case-studies. These case-studies exhibit two types of factors which tend to hamper fidelity in reproducing a given scenario:

- first, constraints on the teacher resulting from the didactical system: time constraints, success of the teaching process;

- second, teachers' conceptions about mathematics and learning. These results are considered with reference to prior research on didactical transposition and teacher's beliefs.
