Experimental Findings

This paper examines the logical problem of language acquisition drawing upon an experimental study on children’s knowledge of anaphoric <em>one</em> by Lidz, Waxman and Freedman (2003). The finding was that, upon being presented with the instruction “<em>Look! A yellow bottle. Do you see another one?</em>”, 18-month-old children prefer to look at a yellow bottle rather than to a bottle of a different color. According to Lidz et al. (2003), the results that children cannot interpret <em>one</em> as anaphoric to head nouns. We point out that the experimental findings are not explained under the hypothesis offered by the authors of that study. Secondly, we consider whether, under current assumptions, children’s knowledge of anaphoric <em>one</em> can be inferred from the properties of the final state. Thirdly, we reaffirm the validity of the Poverty of the Stimulus argument, despite the challenge posed by the learning model proposed by Regier and Gahl (2004). Finally, we draw upon recent psycholinguistic work to propose an explanation for the findings documented by Lidz et al. (2003) that is independent from – though consistent with – their knowledge of the constraint on anaphoric <em>one</em>.

Abstract This paper reports on an experimental study that investigates the influence of the disparity between English and Arabic on second language acquisition, namely the phenomenon of the acquisition of the English dative alternation by Arab learners. The disallowance of certain Arabic verbs to occur in the double object dative structure causes difficulty for Arab learners to acquire English as far as the acquisition of the dative alternation is concerned. The experiment is devised to examine whether Arab learners are sensitive to syntactic and semantic properties associated with the English dative alternation. The experiment involved picture tasks with two structures: the prepositional dative structure and the double object dative structure. Overall, the results of the experiment show that the L2 learners failed to acquire the double object dative structure which does not exist in their L1. Based on these results, it is argued that L1 has an important effect on the acquisition of L2.

Learning science in SMPN 1 Padang has been running pretty well in accordance with the curriculum of 2013. However, there are still shortcomings in the aspect of attitude. Such as low self-care among others, mutual esteem is very low when friends come forward, attitudes tend to be selfish and apathetic attitude towards the environment, resulting in low competence of the social attitudes of learners. One of the ways that teachers can do is to implement cooperative learning model Numbered Head Together (NHT). This study aims to determine the effect of cooperative learning model Numbered Head Together (NHT) the competence of the social attitudes of students of class VII SMPN 1 Padang. This study was an experimental study with a quasi-experimental methods (quasi-experimental). The study population was the students of class VII SMPN 1 Padang. Sampling was done by purposive sampling with learners VII.D class as the control class and the class as a class experiment VII.E. The instrument used is the observation sheet attitude competence of learners. The result shows that there are improvement of students social attitude competence after using NHT in class VII SMPN 1 Padang. Factors include are discussed.

Experimental Findings

The scope of this work shows novel experimental findings on preparing anatase TiO2 nanoparticles, first anodizing titanium into an organic media for obtaining TiO2 nanotubes, and using these as a photocatalytic active electrode in treating water polluted with organic contaminants. The substrates were grit blasted to obtain mechanical fixation of the generated nanotubular TiO2 structure. This was successfully achieved without diminishment of the nanotubes order and with a self-leveling of the outer surface. A new phenomenon has been investigated consisting of the process of oxidation of the nanotubes in water after anodizing. Along this process, methyl orange added to the aqueous solution was discolored as part of the redox reaction involved. The final state of the modified layer was composed of conglomerates of almost completely crystalline TiO2 nanoparticles, around 4 nm in size, consisting of anatase. SEM and TEM images show the transition of the amorphous nanotubes (atomic disorder/nanometric order) to crystalline disordered particles (atomic order/nanometric disorder).

Probabilistic Nature

MacWhinney (2004) has provided a clear and welcome synthesis of many strands of the recent research addressing the logical problem of first language acquisition from a non-nativist or non-generative grammar framework. The strand that I will comment on is the one MacWhinney calls the ‘pivot’ of his proposal, namely, that acquiring a grammar is primarily a function of learning ITEM-BASEDPATTERNS (e.g. pp. 23–29, 41, passim). These item-based patterns serve a number of dominant roles within MacWhinney's proposal, including enforcing children's conservatism (thereby reducing greatly their overgeneralizations and need to recover from the same), supporting the probabilistic nature of grammar, and enabling the competition that promotes recovery from the overgeneralizations that do occur. My concern here is primarily with the first role, that of enforcing children's conservatism, and especially with the exclusive use of language PRODUCTION as the demonstrated support of this conservatism.
