this study was conducted to investigate the impact of portfolio assessment as a process-oriented assessment mechanism on iranian efl students’ english writing and its subskills of focus, elaboration, organization, conventions, and vocabulary. out of ninety juniors majoring in english literature and translation at the university of isfahan, sixty one of them who were at the same level of writing...
Fishery biology, particularly the applied aspect of stock assessment, became a truly quantitative science in the mid-1950s, when the Beverton & Holt and Schaefer"workhorse" models for stock assessment were produced. Unfortunately, the computations involved in using either of these models and their variants and successors were generallyquite tedious. In the 1960s and early 1970s, various authors...
dynamic assessment according to vygotskys sociocultural theory, states that instruction and assessment are interrelated. using static forms of assessment with second and foreign language students could do more harm than good. many teachers neglect to take account of the complexity involved in learning a second or foreign language and often wonder why learning of a language take so long. thi...
abstract this study aimed at investigating the possible relationship between self-assessment in writing and self-regulation of iranian efl learners. the main purpose of the study was not only to report and inform about this relationship, but also to investigate and find practical outcomes of the incorporation of self-assessment in writing, such as improving writing skill. the research was carr...
nothing affects learners more than assessment, so it is important to involve them in assessment process. involvment of learners in assessment helps them to become autonoumos learners. despite this importance iranian learners specialy javanroodian ones are not activily involved in the process. hence the aim of this thesis is to invesrtigate thier ability in th eassessment process
A basic sh-stock assessment system requires an integrated use of a model for the time evolution of a sh stock and information about the sh stock from catch data. Typical for common sh stock assessment systems have been the use of fairly sim-plistic data assimilation methodologies for the integration of observations with the dynamical models. On the other hand, there has been a fast development ...
Stock identification has been an important prerequisite for stock assessment throughout its history. The earliest evaluations of recruitment variability recognized that understanding the spatial scale of a fishery resource is essential for studying population dynamics. A paradigm of stock structure was based on closed migration circuits and geographic variation of phenotypic traits and formed a...
for assessment of portfolio performance, it's crucial to adjust the return by the risk which is taken. so it seems undeniable that for measuring the risk-adjusted return of portfolio, we need an appropriate and developed model for risk and asset pricing. fama & french 3 factor model could explain several return anomalies. recent studies show that capital productivity effects on stock retur...
Data used in stock assessment models result from combinations of biological, ecological, fishery, and sampling processes. Since different types of errors propagate through these processes it can be difficult to identify a particular family of distributions for modelling errors on observations a priori. By implementing several observational likelihoods, modelling both numbersand proportions-at-a...
