In this study, an extension of Klahr and Nigam (2004), we tested 177 middle school students’ on their acquisition of the control of variables strategy (CVS) using an interactive virtual ramp environment. We compared the effectiveness of three pedagogical approaches, namely, direct instruction with reification, direct instruction without reification, and discovery learning, all of which were aut...

Automatic language identi cation (LID) from the spoken speech utterance is a challenging problem. In this paper, we present an LID system that works for South Indian languages and Hindi. Each language is modeled using an approach based on Vector Quantisation [1]. The speech is segmented into di erent sounds (CVs) and the performance of the system on each of the segments is studied. Our studies ...

Automatic analysis of curriculum vitae (CVs) of applicants is of tremendous importance in recruitment scenarios. The semi-structuredness of CVs, however, makes CV processing a challenging task. We propose a solution towards transforming CVs to follow a unified structure, thereby, paving ways for smoother CV analysis. The problem of restructuring is posed as a section relabeling problem, where e...

In this paper we present a rule-based technique for the automatic extraction of Bangla compound verbs from raw text corpora. In our work we have (a) proposed rules through which a system could automatically identify Bangla CVs from texts. These rules will be established on the basis of syntactic interpretation of sentences, (b) we shall explain problems of CV identification subject to the seman...

Job applicants in Europe and in Israel increasingly imbed a headshot of themselves in the top corner of their CVs. We sent 5312 CVs in pairs to 2656 advertised job openings. In each pair, one CV was without a picture while the second, otherwise almost identical CV contained a picture of either an attractive male/female or a plain-looking male/female. Employer callbacks to attractive men are sig...

Qualitative and quantitative differences in semantic priming for native and nonnative speaker groups were explored using a primed lexical decision task. In addition to response time data, coefficient of variance (CV) for response times was used to investigate quantitative differences in lexical processing between groups. Segalowitz and Segalowitz (1993) argued that differences in CV indicate pr...

In this study, we address whether learner characteristics can provide data to inform adaptive scaffolding of scientific inquiry skills in our learning environment, Science Assistments. We found that academic efficacy positively predicted students’ skills at generating hypotheses; another subscale, skeptical of school relevance, negatively predicted students’ skills at conducting controlled expe...
