The potential formative benefits of portfolio assessment in second and foreign language writing contexts: A review of the literature

This article identifies the potential formative benefits of using portfolio assessment (PA) in second/foreign language classrooms by reviewing the up-to-date research. Three methods were used to search for relevant research: database search, manual search, and citation search. According to the literature, PA has potential benefits due to its process-oriented, authentic, integrated, interactive, and learner-centered characteristics. PA leads to increased motivation, learner autonomy, and improved writing performance. However, not many studies include observation as a method of collecting data. Through observation a researcher can investigate how the benefits of PA are acted upon and negotiated. There is a need for more empirical research in the juxtaposition of PA and formative assessment, particularly in primary and secondary education.     

Diagnosing Teachers’ Understandings of Rational Numbers: Building a Multidimensional Test Within the Diagnostic Classification Framework

We report a multidimensional test that examines middle grades teachers’ understanding of fraction arithmetic, especially multiplication and division. The test is based on four attributes identified through an analysis of the extensive mathematics education research literature on teachers’ and students’ reasoning in this content area. We administered the test to a national sample of 990 in‐service middle grades teachers and analyzed the item responses using the log‐linear cognitive diagnosis model. We report the diagnostic quality of the test at the item level, mastery classifications for teachers, and attribute relationships. Our results demonstrate that, when a test is grounded in research on cognition and is designed to be multidimensional from the onset, it is possible to use diagnostic classification models to detect distinct patterns of attribute mastery.     

Reference power values for the jump squat exercise in elite athletes: A multicenter study

ABSTRACT

The present study aimed to provide reference values for lower-limb muscle power assessed during the incremental jump squat (JS) test in elite athletes (i.e., professional athletes competing at international level). We pooled data from all JS tests performed by elite athletes of different sports in two high-performance centres between 2015 and 2019, and computed reference values (i.e., terciles) for mean power (MP), mean propulsive power (MPP), and peak power (PP). Reference values were obtained from 684 elite athletes (458 male and 226 female) of 16 different sports (boxing, judo, karate, fencing, taekwondo, wrestling, basketball, soccer, futsal, handball, rugby union, badminton, tennis, long distance running, triathlon, and sprinting). Significant differences (p < 0.001) were found between male and female athletes for MP (7.47 ± 1.93 and 6.15 ± 1.68 W·Kg^?1, respectively), MPP (10.50 ± 2.75 and 8.63 ± 2.43 W·Kg^?1), and PP (23.64 ± 6.12 and 19.35 ± 5.49 W·Kg^?1). However, the velocity at which these power measures was attained seemed to be independent of sex (~0.95, 1.00 and 2.00 m·s^?1 for mean, mean propulsive, and peak velocity, respectively) and homogeneous across different sport disciplines (coefficient of variation <10%). These data can be used to classify athletes’ power capabilities, and the optimum velocity ranges provided here could be useful for training purposes.     

Uncovering the Evidence: Faculty Perceptions of Distance Library Services

Usage statistics are a regular part of assessment but the lack of context leaves librarians pondering the reasons for fluctuations in use. Through development of an online survey, we examined faculty perceptions, knowledge, and use of distance library services to support online courses. Responses provided much needed context and helped to determine priorities and direction for services. While this survey was a useful marketing tool, results emphasized that the greatest need was for ongoing communication with faculty to increase awareness of services provided.     

文体分析在大学英语综合课中的应用

主要基于功能文体学的研究模式,按决定语域的三个情景变项-话语范围、话语方式和话语基调,从语音、词汇语法和篇章三层次,主要从词汇语法层分析《大学英语》(全新版)综合教程中语言变体的文体特征,阐明文体分析在大学英语综合课教学中的应用。文体分析有利于加强学生对语言特征的积累,提高使用语言的合适性,有助于实现折中法的教学方法。
