基于认知诊断测评的个性化补救教学效果分析：以“一元一次方程”为例

基于“为学习而测评”理念,以促进学生学习为目的,本研究进行了基于认知诊断测评的个性化补救教学效果分析。首先,以“一元一次方程”章节为例,编制两份平行的认知诊断测评试卷。然后,通过对不同地区（城市和农村）七年级学生的施测与分析,发现城市学生对属性的掌握情况优于农村学生对属性的掌握情况。之后,选择农村学生为补救对象,通过对比基于认知诊断测评和传统教学两种个性化补救教学的效果,发现两种补救教学方法均能提高学习成绩,但前者的补救效果显著优于后者的。总之,本研究结果表明采用基于认知诊断测评的个性化补救教学能够有效促进学生学习,为实践者应用认知诊断测评促进学生学习提供了实践依据。     

Effects of Error Correction on Spanish Spelling Words for Students Whose Primary Language Is Spanish

The purpose of this study was to examine the effects of an error correction strategy on the spelling accuracy of Spanish words by elementary school students who come from a bilingual home environment, where the home language is Spanish. In the error correction strategy students wrote the word, viewed an accurate model of the word, and self-corrected any errors. In the traditional strategy students wrote each word three times on a paper after viewing an accurate model. All words and examples were presented in the student's home language (Spanish). Results showed that students spelled more words correctly under the error correction strategy.     

The Effects of Partner Learning During Spelling for Students with Severe Disabilities and Their Peers

A multiple baseline across subjects design was used to examine the effects of partner learning on the spelling performance, academic responding, and competing behavior of three students with severe disabilities and three of their classmates without disabilities. The students were enrolled in different general elementary classes. All students in these classes were assigned to partner learning triads by the general education teacher. One triad in each class included the student with severe disabilities and two classmates without disabilities. All students in the class received two, 20 min partner learning sessions each week. During partner learning, each member of the triad was asked to spell words, present words to be spelled, provide feedback to the speller, and check the spelling accuracy. These roles were rotated among the members of the triad after each trial. These roles were adapted as necessary to accommodate the academic and communication skills of the students with severe disabilities. The effects of partner learning on spelling accuracy were assessed through weekly spelling tests. The effects of partner learning on academic responding and competing behavior were assessed using the MS-CISSAR (Carta, Greenwood, Schulte, Arreaga-Mayer, Terry, 1988). Results of weekly spelling indicated that partner learning led to improved spelling accuracy for students with severe disabilities and did not negatively affect the spelling accuracy of their peers. Partner learning also led to improved rates of academic responding and reduced rates of competing behavior for 5 of 6 students. The results are discussed in terms of their implications for practice and future research.     

The Foundations of Literacy

Learning to read and write in English requires children to master the alphabetic principle, the idea that the letters in printed words represent the sounds in spoken words in a more or less regular manner. Children need at least two skills in order to grasp the alphabetic principle. The first is phonological awareness, or a sensitivity to the sound structure of spoken words. The second is knowledge about letters, including knowledge of letter names and knowledge of letter sounds. Recent research sheds light on these foundational skills, documenting the linguistic factors that affect children's performance and how children put their phonological skills and knowledge of letters to use in learning to read and spell.     

Effects of teacher-directed versus student-directed instruction and cues versus no cues for improving spelling performance

THE PURPOSE OF THIS STUDY WAS TWOFOLD: to examine the effects of imitating children's spelling errors alone and in combination with visual and verbal cues on spelling accuracy and retention among poor spellers and to compare the effectiveness of student-directed versus teacher-directed spelling instruction on children's spelling accuracy and retention. Nine children received four alternating experimental treatments during a 16-week spelling program. Results indicated that student-directed instruction that incorporated visual and verbal cues was most effective in increasing children's spelling accuracy.     

Classroom applications of stimulus equivalence technology

We review basic concepts and methods of stimulus equivalence research and suggest applications in teaching rudimentary language arts skills in the classroom. We describe methods of establishing equivalence-based networks of matching-to-sample, writing, and naming performances. The methods may be used as a supplement to classroom instruction to assess whether standard curriculum-based approaches establish such integrated networks. Methods derived from equivalence research may be useful for remediation when traditional teaching approaches fail. Recent research suggests that direct focus on spelling performances may be required if entire networks of language arts skills are to be acquired. In addition, the equivalence relations themselves may require concentrated teaching in some children.     

The Effects of Self-Correction Versus Traditional Spelling on the Spelling Performance and Maintenance of Third Grade Students

We examined the effect of self-correction versus a traditional spelling approach on the acquisition and maintenance of written spelling of elementary school students enrolled in third grade. Six students, who were at risk for spelling failure, served as subjects. During self-correction, students used a form with five columns that contained correct pre-written models of spelling words. After reviewing the word list, students folded back the first column, which contained the words. Then, they listened to their spelling list on individual cassette players and spelled each word in turn in the subsequent columns of the form. Students checked their spelling responses by unfolding the first column and matching their responses to the sample. Each correct spelling response was marked with a C incorrect spellings were fixed by writing the correct orthography above the word. During traditional spelling, students wrote each spelling word five times, using a pre-written model as a guide. Results showed a functional relationship between self-correction and improved spelling performance. Five of the six maintained a higher number of posttests words on maintenance probes. All students preferred the self-correction method over the traditional spelling method.     

Classwide Peer Tutoring: Effects on the Spelling Performance and Social Interactions of Students with Mild Disabilities and Their Typical Peers in an Integrated Instructional Setting

The effectiveness of Classwide Peer Tutoring (CWPT) to enhance the spelling performance and social interactions of three typical students and three students with mild disabilities was investigated. The classroom ecology was measured using the New Code for Instructional Structure and Student Academic Response (NCISSAR). Social interactions were assessed using the Multiple Option Observation System for Experimental Studies (M.O.O.S.E.S.). Spelling performance was measured by weekly pre-posttests. Using an ABAB single-subject design, results indicated that CWPT resulted in: (a) gains in the spelling accuracy of all students (up to 49%), (b) increases of students' duration of positive social interactions (up to 86%), and (c) high satisfaction ratings for both the students and the teacher. Comparisons between typical students and students with mild disabilities during CWPT suggested no differences in their duration of social interactions. Furthermore, the mean spelling accuracy of the students with mild disabilities was comparable to the spelling accuracy of the typical students (91% vs. 96%, respectively). Implications of the findings for the inclusion of students with mild disabilities in general education settings are discussed.     

TEACHING CHILDREN TO SPELL: DECREASING CONSONANT CLUSTER ERRORS BY ELIMINATING SELECTIVE STIMULUS CONTROL

Six elementary-aged children were taught to spell words containing initial consonant clusters (CCs). They were trained to select printed words in response to the corresponding spoken words using computerized matching-to-sample procedures. After each training session, they were tested for spelling with a constructed-response transfer test. Based on previous selective stimulus control research, we hypothesized that only the first letter of an initial CC might control spelling when CC spelling errors are made. Thus, a critical-difference matching-to-sample training condition that required the children to respond to both letters of the CC to be correct was compared to a multiple-difference training condition that required the children to respond to only one letter of the pair. Results showed that children made fewer errors during the multiple-difference training condition than during the critical-difference training condition. On the constructed-response transfer tests, however, more overall errors and CC errors were made in the multiple-difference condition than in the critical-difference condition, and the words trained in the multiple-difference condition required more training sessions to reach criterion. All children improved their spelling of novel CC words by the completion of training. If normal classroom or home reading was to be supplemented by computer tasks of the kind used here, some spelling problems could be circumvented without costly intervention by a teacher or a special trainer.
