The level of abstraction of textual materials: a new and an old measure compared     

Douglas P. Newton 《Journal of Research in Reading》1992,15(2):117-119

The level of abstraction of textual material is one factor affecting the difficulty it presents to the reader and so effective ways of assessing it are potentially useful for the teacher and researcher. A ‘new’ measure was compared with an old one and some similarity found in their assessment of science texts. The earlier measure may be the easier one for the non-specialist to use. The results also suggested a rule of thumb which practising teachers might find useful.  相似文献

Do NESB University Students with Poor English Skills Make Rapid Linguistic Gains in Mainstream Studies?     

Douglas Farnill  Susan Hayes 《高等教育研究与发展》1996,15(2):261-268

This paper reports the testing and retesting two years later of 147 first‐year medical students for English language proficiency (ELP). A group of 66 with low initial proficiency, all of non‐English‐speaking background (NESB), improved from an average language age of 14.3 years to 15.2 years over the period. A comparison group of 81, randomly drawn from those who were of adequate ELP, 48% of whom were NESB, were close to the test ceiling on both occasions with an age equivalence of 33 years. Generalisation to other courses and samples may be limited but this study did not indicate great linguistic gains associated with mainstream studies for those whose English was poor at the beginning of their course.  相似文献   

Stress Reactivity and Self-Recognition   总被引：1，自引：0，他引：1  

Michael Lewis  Douglas S. Ramsay 《Child development》1997,68(4):621-629

This study examined longitudinally whether early differences in reactivity to stress are related to self-recognition at 18 months of age. Adrenocortical and behavioral to Stress responses to routine inoculation at 2, and 4 months and at 6 and 18 months were obtained. Previous finding indicated a development shift in adrenocortical functioning by 6 months of age that included the emergence of stable individual differences in cortisol response from this point in development. Self-recognition was related to greater cortisol response and less rapid quieting at 6 to 18 months, whereas 2- to 4-month cortisol and quieting response did not differentiate self-recognizers and non-self-recognizators. These findings indicate a role for temperament differences in facilitating the emergence of self-recognition.  相似文献

Lawson's Shoehorn, or Should the Philosophy of Science Be Rated ‘X’?     

Douglas Allchin 《Science & Education》2003,12(3):315-329

Lawson's (2002) interpretations of Galileo's discovery of the moons of Jupiter and other cases exhibit several historical errors, addressed here both specifically and generally. They illustrate how philosophical preconceptions can distort history and thus lessons about the nature of science.  相似文献   

Novice Supervisees' Self‐Evaluations and Their Perceptions of Supervisor Style     

Robbie J. Steward  Alfiee Breland  Douglas M. Neil 《Counselor Education & Supervision》2001,41(2):131-141

Multiple regression analyses of data obtained for 36 counseling supervision dyads indicated that attractiveness, an aspect of supervisory style, was negatively associated with supervisees' self‐evaluations and positively associated with the difference between trainees' and supervisors' evaluations of counseling competence at the end of the 1st practicum experience. Supervisors' interpersonal sensitivity and task orientation were not found to contribute significantly to either of the criterion variables.  相似文献   

Tiers of intervention in responsiveness to intervention: prevention outcomes and learning disabilities identification patterns     

Marston D 《Journal of learning disabilities》2005,38(6):539-544

Response to Intervention (RTI) models have attracted great attention as an alternative to traditional methods used for identifying students with learning disabilities. A major feature of this approach is the implementation of academic interventions in general education and measuring the student's response to those interventions. A common question that needs to be addressed is the number of stages or tiers of intervention necessary in the Response to Intervention model. This article reviews three studies of RTI that investigate the RTI tiers. Sharon Vaughn and Rollanda O'Connor report on studies using the Standard Protocol approach to RTI. David Tilly reports on using the Problem Solving Model as an RTI model. This article summarizes the results of these three investigations.  相似文献   

Further evidence that conditioned inhibition is not the mechanism of an extinction cue’s effect: A reinforced cue prevents spontaneous recovery     

Douglas C. Brooks  Jonna L. Bowker 《Learning & behavior》2001,29(4):381-388

Previous research has demonstrated that discrete cues presented during extinction of a conditioned response (extinction cues) subsequently reduce spontaneous recovery and the renewal effect. In order to assess whether an extinction cue’s effect is due to conditioned inhibition, the effect of pairing an extinction cue with food on the cue’s capacity to modulate spontaneous recovery was investigated in an appetitive conditioning experiment with rats. Conditioned inhibitors paired with the unconditioned stimulus lose their potential to inhibit responding. The food-paired extinction cue did not lose its potential to reduce spontaneous recovery. In fact, it reduced spontaneous recovery more than did an extinction cue that was not paired with food. The results indicate that extinction cues attenuate postextinction recovery of conditioned responding through a mechanism other than conditioned inhibition. The cue’s action appears to be similar to that of serial negative occasion setters. Theories of spontaneous recovery and the relationship of extinction cues to other modulatory stimuli are discussed.  相似文献   

Generative aspects of the Computer Based Educational Software System (CBESS)     

C. Douglas Wetzel 《Instructional Science》1992,21(4):269-293

A system of computer-based instruction (CBI) authoring and delivery tools was developed in which generative CBI techniques were used to dynamically create instructional presentations from content databases during program execution. Three applications using these techniques are examined with regard to trade-offs between case of development and limitations imposed by program specificity: 1) A semantic network was used to represent large bodies of terse facts to be memorized. The need for authors to create large numbers of question screens was avoided by a feature enabling questions and foils to be generated on-the-fly from database assertions as the student programs ran. 2) Technical vocabulary training was accomplished with a generative approach in which an array of student learning activities were automatically generated from a database minimally consisting of technical terms and their definitions. 3) A more difficult program allowed greater interface and lesson control flexibility for creating more sophisticated practice lessons in which new instances were dynamically inserted into templates for questions, anticipated answers and feedback. A common application theme emerging from field-testing the programs was their use in learning resource centers to address specific learning objectives from larger courses.  相似文献
