 In this revision, three species are recognised. A discussion is made on merging the genus Polysolenia into Leptomischus. Indopolysolenia burmanica Deb et Rout is reduced to a synonum of Leptomischus primuloides Drake.  A key to species is given below: l. Flowers larger, with corollas more than 2cm long.   2.Stipules 3-fid or torn;  Leaves narrowly lanceolate;  stigmas with 2 short obtuse     lobes  ......................................................  1.L. wallichii   2.Stipules entire;  leaves obovate to elliptic;  stigmas with 2 slender elongate lobes         .........................................................  2. L. primuloides 1.Flowers smaller, with corollas 6-6.5mm long;  stigmas with 2 lanceolate lobes       ..........................................................  3. L. parviflorus     

The research and evaluation of serious games: Toward a comprehensive methodology

The authors present the methodological background to and underlying research design of an ongoing research project on the scientific evaluation of serious games and/or computer‐based simulation games (SGs) for advanced learning. The main research questions are: (1) what are the requirements and design principles for a comprehensive social scientific methodology for the evaluation of SGs?; (2) to what extent do SGs contribute to advanced learning?; (3) what factors contribute to or determine this learning?; and (4) to what extent and under what conditions can SG‐based learning be transferred to the real world? In the Netherlands between 2005 and 2012, several hundred SG sessions with 12 SGs were evaluated systematically, uniformly and quantitatively to create a dataset, which comprises data on 2488 respondents in higher education or work organizations. The authors present the research model, the quasi‐experimental design and the evaluation instruments. This focus in this paper is on the methodology and dataset, which form a sound foundation for forthcoming publications on the empirical results.     

Syntactic and discourse skills in Chinese adolescent readers with dyslexia: a profiling study

This study aims to investigate the relation of syntactic and discourse skills to morphological skills, rapid naming, and working memory in Chinese adolescent readers with dyslexia and to examine their cognitive–linguistic profiles. Fifty-two dyslexic readers (mean age, 13;42) from grade 7 to 9 in Hong Kong high schools were compared with 52 typically developing readers of the same chronological age (mean age, 13;30) in the measures of word reading, 1-min word reading, reading comprehension, morpheme discrimination, morpheme production, morphosyntactic knowledge, sentence order knowledge, digit rapid naming, letter rapid naming, backward digit span, and non-word repetition. Results showed that dyslexic readers performed significantly worse than their peers on all the cognitive-linguistic tasks. Analyses of individual performance also revealed that over half of the dyslexic readers exhibited deficits in syntactic and discourse skills. Moreover, syntactic skills, morphological skills, and rapid naming best distinguished dyslexic from non-dyslexic readers. Findings underscore the significance of syntactic and discourse skills for understanding reading impairment in Chinese adolescent readers.

Teaching for deeper political learning: a design experiment

Is in-depth political learning possible in college-preparatory courses known for curricular breadth at an accelerated pace plus a high-stakes exam? A multidisciplinary research team conducted design-based implementation research (DBIR) for seven years across three school systems for the purpose of achieving deeper learning in an ‘advanced’ high school government and politics course. This article reports findings from the final year of research and development. The design centres on cyclical learning, projects (simulated political processes) and strategic use of texts as resources for learning the curriculum. Quantitative analysis shows comparable achievement to students in traditional classrooms on the high-stakes summative assessment despite the dramatic departure from test-prep instruction. Qualitative analyses focus on two of the design elements: learning from simulations and learning from text. The first allowed students to ‘experience’ political beliefs, institutions, and conflict, although simulated; the second required students to learn subject matter not only from simulations and teacher lectures but from texts, too. The discussion shows how these two in combination with cyclical learning required skilful attention to content selection. We conclude that when deeper learning is the goal, content selection cannot be elided or presumed, particularly with respect to the articulation of depth and breadth in curriculum and instruction.
