This study investigated the effects of group personalization of instruction on the mathematics achievement and attitudes of 72 fifth-grade Taiwanese students. Personalization was accomplished by incorporating personal information and preferences provided by students into their mathematics word problems. Students were blocked by ability level, then randomly assigned to a personalized or nonpersonalized version of an instructional program on mathematics word problems. Students made significant pretest-to-posttest gains across treatments and scored significantly higher on personalized than on nonpersonalized posttest problems. However, the personalized treatment did not produce a significant achievement difference over the nonpersonalized one. Significant two-way interactions reflected greater pretest-to-posttest improvement for lower-ability than for higher-ability students and a greater difference between scores on personalized over nonpersonalized posttest problems for lower-ability students. The posttest scores of high-ability students were limited by a ceiling effect. Student attitudes were significantly more favorable toward the personalized instruction.  相似文献

This study investigated the effects of three levels of personalization—individualized, group, and non-personalized—on the mathematics achievement of 123 seventh-grade Hispanic boys and girls. Personalization was accomplished by using personal information provided by students on a biographical inventory. Subjects were randomly assigned within sex to one of three versions of a two-day instructional program on one-step and two-step mathematics word problems. Subjects in both the individual and group personalization treatments scored significantly higher on the posttest than those in the nonpersonalized treatment on two-step word problems, but not on one-step problems. Subjects in the individualized treatment had significantly more positive attitudes toward the instruction than those in the other two treatments.  相似文献

This study examined the effects of program mode (i.e., a lean program version containing a basic amount of learner practice vs. a full mode containing expanded practice) and learner preference (matched or unmatched) for amount of practice on the achievement, time-in-program, and attitudes of university undergraduate students. Subjects completed a 10-item Likert-type prequestionnaire to indicate the amount of practice they preferred, then were randomly assigned to either the type of program they preferred or to the opposite type. Subjects who used the full version of the instructional program scored significantly higher on the posttest than those who used the lean version. Matching subjects to their preferred amount of practice did not yield a significant achievement difference over assigning subjects to their less-preferred amount. Subjects preferred the lean version of the program over the full one, even though the full version produced better test performance.  相似文献

This study investigated the effects of two types of control over instruction (learner and program) and two modes of instructional programs (lean and full) on the achievement, option use, and time-in-program of 274 high-ability and low-ability students from grades 9 and 10. The basic instructional program in geometry was delivered by computer. Subjects under learner control scored significantly higher on the program posttest than those under program control, spent significantly more time in the program, and liked it better. Learner-control subjects appeared to “trust” their given version of the program, viewing many more optional screens in the full version than those in the lean one. High-ability learners adapted their study behavior to the lean version under learner control by choosing significantly more optional screens than their low-ability counterparts. This research was conducted while he was a graduate student at Arizona State University where Howard J. Sullivan is a professor in Learning and Instructional Technology.  相似文献

Learner-control strategies for selecting problem context and the level of instructional support were examined separately and in combination on a computer-based mathematics unit on the metric system. Subjects were 240 sixth-grade students assigned to 15 treatments formed by crossing five context conditions (animals, sports, clothing, nocontext, and learner control) with three instructional support conditions (minimum, maximum, and learner control). As hypothesized, comparisons of instructional support conditions on posttest achievement showed performance to be lowest under learner control. Subjects opted to view very few items and to decrease the amount they selected over the course of the instruction. No effects were associated with the context variable, although on one of the three lessons, learner-control subjects made significantly fewer on-task errors than did no-context subjects. Further analyses showed a strong tendency by learner-control context subjects to vary their selection of contexts across lessons. Subjects in the context and instructional support learner-control strategies indicated positive attitudes toward the strategies.  相似文献

This study was conducted with 75 United States and Far East employees of a major corporation to investigate the effects of assigning learners to either the amount of instruction they preferred or to the contrasting amount. Subjects completed a 10-item Likert-type prequestionnaire to indicate whether they preferred a basic instructional program or a more comprehensive one, then were randomly assigned either to the type of program they preferred or to the opposite type. Subjects who received the amount of instruction that matched their preference scored significantly higher on the posttest, spent significantly less time in the program, and had significantly more positive attitudes on four of the six attitude items. Further research is recommended to determine the generalizability of the present findings to other subject populations.  相似文献

Spatial ability and transformational geometry   总被引：1，自引：0，他引：1  
New technologies in education are placing more emphasis upon visual and spatial skills, those required to inspect, encode, transform, and construct information in visual displays. They do this by presenting students with learning material embedded in complex visual displays and hypermedia, and by requiring students to navigate through virtual space. These developments make it important for us to learn more about the underlying nature of visuospatial ability, how it is related to academic performance, and how it can be improved. This paper explores these issues in the context of instruction in transformational geometry upon geometry performance and spatial ability of Grade 7/8 students. The instructional conditions were (a) a traditional textbook approach involving paper-and-pencil tasks and verbal instruction (Traditional Group), and (b) an approach incorporating object manipulation, and visual imagery, which was designed to encourage spatial thinking (Spatial Group). Multiple regression results indicated that posttest geometry performance was predicted by pretest geometry, pretest spatial ability, and the interaction of pretest geometry and instructional condition; the interaction indicated that high prior knowledge subjects performed better in the Spatial group, low prior knowledge subjects in the Traditional group. Posttest spatial ability was predicted by handedness, pretest geometry, pretest spatial ability, and the interaction of pretest spatial ability and handedness; the interaction indicated that less right-handed subjects of low spatial ability improved on spatial ability more than their more right-handed peers.  相似文献

Abstract

In this study we describe and examine the effectiveness of an instructional program designed to teach learning disabled adolescents to make better personal decisions. We presented problems in short narratives based on the types of problems these students must solve in their own lives. The program, conducted as part of the students' regular resource room curriculum, incorporated schema‐general questions for problem solving coupled with practice in generating problem‐specific questions to reach an appropriate decision. Participants were 70 resource room students in two large, urban high schools. We employed a pretest‐posttest comparison group design. On the posttest, instructed students performed significantly better on (1) identifying a general schema for making a personal decision and (2) applying the schema to reach appropriate decisions concerning novel problem narratives. The results support the view that application of a general schema to specific problems can be an effective instructional method to improve critical thinking and decision making.  相似文献

QuickSmart is a basic academic skills intervention designed for persistently low-achieving students in the middle years of schooling that aims to improve the automaticity of basic skills to improve higher-order processes, such as problem solving and comprehension, as measured on standardized tests. The QuickSmart instructional program consists of three structured, teacher- or teacher aide-directed, 30-minute, small-group lessons each week for approximately 26 weeks. In this study, 42 middle school students experiencing learning difficulties (LD) completed the QuickSmart reading program, and a further 42 students with LD took part in the QuickSmart mathematics program. To investigate the effects of the intervention, comparisons were made between the reading and mathematics progress of the intervention group and a group of 10 high-achieving and 10 average-achieving peers. The results indicated that although the standardized reading comprehension and mathematics scores of QuickSmart students remained below those of comparison students, they improved significantly from pretest to posttest. In contrast, the standardized scores of comparison students were not significantly different from pretest to posttest. On measures of response speed and accuracy gathered using the Cognitive Aptitude Assessment System (CAAS), QuickSmart students were able to narrow the gap between their performance and that of their high- and average-achieving peers. Implications are drawn regarding the importance of interventions that emphasize the automaticity of basic academic skills for students with learning difficulties.  相似文献

This study investigated the effects of learner control and program control on the achievement and continuing motivation of high school students. The influence of the availability of computer-delivered instruction on student motivation was also examined. Continuing motivation was measured by student choice of learner control or program control as the mode for a second instructional program after subjects completed an initial program under their randomly assigned mode. Results revealed a highly significant difference in continuing motivation favoring learner over program control. The differences in posttest performance and performance during instruction between learner and program control were not significant. The data also revealed significant preferences to study both science and an alternative subject when they are presented by computer over when they are not.The research reported herein was conducted while she was a doctoral student at Arizona State University.  相似文献

This study investigated the effects of teacher evaluation and the combination of teacher evaluation and student self-evaluation on student performance and attitudes. Participants in the study were 189 Latvian high school students and their six teachers. The six teachers were assigned to one of three treatment conditions: (a) no evaluation, (b) teacher evaluation, and (c) self-evaluation plus teacher evaluation. All groups completed a 12-lesson instructional program on how to conduct experiments and produce research reports. Students in the teacher-evaluation group received teacher evaluation on their initial research reports. Students in the self-plus-teacher evaluation group self-evaluated their reports and received teacher evaluation on them. The no-evaluation group received no formal evaluation instructions. Students in the teacher-evaluation and the self-plus-teacher evaluation groups received significantly higher ratings on their final projects than those in the no-evaluation group. However, the no-evaluation group had more favorable attitudes toward the program than the other two groups, while the self-plus-teacher evaluation group was significantly more confident of their ability to independently conduct future research experiments. This study was conducted while Dr. Olina was a student at Arizona State.  相似文献

This study examined the effects of type of instructional control and program mode on the achievement, option use, time in the program, and attitudes of higher-ability and lower-ability university students. Ability level was determined using participants' Scholastic Aptitude Test (SAT) and American College Testing Assessment (ACT) scores. Participants were randomly assigned to four versions of a computer-delivered instructional program within higher-ability and lower-ability groups. The four versions of the instructional program were created by crossing the two control conditions (learner control, program control) with the two program modes (full, lean). Participants in the full program scored significantly higher on the posttest than those in the lean program, and higher-ability students scored significantly higher than lower-ability students. Learner-control participants chose to view 68% of the optional screens in the full program but only 35% in the lean one, and participants also spent significantly more time in the full version. Participants had more favorable attitudes toward learner control than program control.  相似文献

This sequential methodologic elaboration study investigated differences between the middle school and the junior high instructional strategies and the effects on adolescent attitude toward science in school and science achievement. Subjects of the quantitative phase were 570 seventh- and eighth-grade students in one school in an urban school district in the midwest United States during a transition year from junior high to middle school. Germann's Attitude toward Science in School Assessment and the school district's Benchmark Exams were employed to measure student pre- and posttest attitude and achievement. Variations within grade level, gender, race, general ability, and socioeconomic group were evaluated. Results of split plots revealed no significant differences in science attitude between the experimental middle school group and the junior high control group at this phase. However, there was significant improvement in attitude in both seventh-grade populations, but no change in attitude in either eighth-grade population. No significant differences in attitude were found between males and females, Caucasian students and students of color, or students of different ability or socioeconomic groups. Significant increases in science achievement were revealed in the seventh-grade junior high control group, the eighth-grade middle school, and the eighth-grade junior high, but not in the seventh-grade middle school. No significant differences in achievement were found between males and females. Caucasians scored significantly higher in achievement than students of color. Average and high ability students scored significantly higher pretest to posttest, but low ability students did not. High ability students scored significantly higher than both average and low ability groups. There was significant improvement in science achievement for students in the sufficient socioeconomic status group, but not in the low socioeconomic status group. These results were discussed with the five science teachers, the principal, and a university consultant in the setting, who were the informants of the qualitative elaboration phase of the study. Ethnographic methods uncovered themes explaining differences and similarities within the two instructional strategies. Teachers' feelings and stages of concern were identified. The results are discussed in terms of effectively implementing changes in instructional strategies and assessing science achievement of early adolescents.  相似文献

This study investigated the effects of a science and society intervention on elementary school students’ argumentation skills and their attitudes toward science. One hundred and eleven fifth grade students volunteered as an experimental group to join a 12-week intervention; another 107 sixth grade students volunteered to be the comparison group. All participants completed the Student Questionnaire at the beginning and end of this study. Observation and interview results were used to triangulate and consolidate the quantitative findings. The data showed that after the intervention, the quality of the experimental group students’ arguments and their attitudes toward science were significantly higher than their comparison group counterparts. In addition, the experimental group boys made significantly greater progress in the quality of their argumentation from the pretest to posttest than the girls; and low achievers made the most significant progress in their attitudes toward science and quality of argumentation. Interviews and observations indicated that their understandings of explanation and argumentation changed over the intervention. This indicated that a science and society intervention can enhance both the ability of students to develop strong arguments and their attitudes toward science.  相似文献

This study compared the fluency and error rates produced when using the Cover, Copy, and Compare (CCC) and a modified CCC procedure (MCCC) called Copy, Cover, and Compare to complete subtraction math problems. Two second‐grade classrooms consisting of 47 total students participated in the study. The following items were administered to participants: (a) a timed pretest, (b) a timed CCC worksheet, (c) a timed MCCC worksheet, and (d) a timed posttest. Then the participants were asked which procedure they liked best. Results revealed significantly higher digits correct per minute (i.e., fluency scores) on the posttest when compared with the pretest scores. Likewise, students' fluency scores were significantly higher under the CCC condition when compared to the MCCC condition. There were no significant differences in accuracy from pretest to posttest nor between the CCC and MCCC conditions. Discussion focuses on implications for modifying instructional strategies, measuring student progress, implications for practice, and directions for future research. © 2009 Wiley Periodicals, Inc.  相似文献

This study investigated the effects of cooperative group composition, student ability, and learning accountability on achievement, interaction, and instructional efficiency during computer-based instruction. A total of 125 sixth- and seventh-grade students were randomly assigned to heterogeneous or homogeneous dyads. Groups were designated as having either group or individual account-ability for mastery of lesson content. Cooperative dyads completed a tutorial on a novel symbolic mathematics topic, featuring basic symbol learning and application of the symbols. Indicators of ongoing cooperation were collected during instruction. Five days later, students completed a posttest. Low-ability students interacted more and completed the instruction more efficiently in heterogeneous than in homogeneous groups. High-ability students completed the instruction more efficiently in homogeneous than in heterogeneous groups. Cooperation was significantly related to achievement for heterogeneous ability groups, but not for either homogeneous high- or low-ability students.  相似文献

Physical science curriculum materials designed to improve the attitudes of below-average students were developed from guidelines which reflected the strengths and weaknesses of these students. The materials were administered to ninth and tenth grade students in three average-low ability physical science classes. Students in these classes had I.Q. scores of less than 100, reading achievement below grade placement, and eighth grade science averages of C or below. A control group of three physical science classes was employed. A form of the Semantic Differential was administered as a pretest and posttest. The student who received the materials demonstrated significant improvement in attitudes toward science class and science laboratory.  相似文献

Word play is an important skill allowing product names, show titles, jokes, poetry and other writings or orations to be interesting, entertaining and well-remembered. This pretest–posttest counterbalanced study compared two instructional approaches for teaching second and third grade students (n = 71) word play skills. Students at a public elementary school in Iowa, United States studied vowel patterns and rhyming as part of the regular school curriculum for literacy through two conditions: a traditional format of reading, pocket charts, worksheets and oral discussion; versus a more concrete approach of arranging objects and corresponding word cards in a chart-like formation. There was no significant difference in student performance between the conditions but an attitude survey indicated that a large majority of students preferred the object boxes for understanding of word play concepts and task enjoyment.  相似文献

In each of two studies, teachers were randomly assigned to either a Virtual Workshop (VW) group that used a computerized professional development program or an Actual Workshop (AW) group that participated in face-to-face professional development, including discussion, feedback, and collaboration. In both studies, teachers’ posttest scores related to their knowledge of the Question Exploration Routine and their plans for using it were significantly higher than their pretest scores. In Study 2, both groups’ posttest scores with regard to implementation and planning of the routine were significantly greater than their pretest scores. There were no significant differences between the groups at posttesting on any measure. The posttest knowledge scores of the whole groups of students and the subgroups of students with LD being taught by both groups of teachers were significantly higher than their pretest scores. All teachers indicated that they were satisfied with the training and the routine. VW teachers in both studies indicated that they were satisfied with the software program.  相似文献

The purpose of this research was to explore how technology can be used to teach technological skills and to determine what benefit flipping the classroom might have for students taking an introductory-level college course on spreadsheets in terms of student achievement and satisfaction with the class. A pretest posttest quasi-experimental mixed methods design was utilized to determine any differences in student achievement that might be associated with the instructional approach being used. In addition, the scalability of each approach was evaluated along with students’ perceptions of these approaches to determine the affect each intervention might have on a student’s motivation to learn. The simulation-based instruction tested in this study was found to be an extremely scalable solution but less effective than the regular classroom and flipped classroom approaches in terms of student learning. While students did demonstrate learning gains, the process focus of the simulation’s instruction and assessments frustrated students and decreased their motivation to learn. Students’ attitudes towards the topic, their willingness to refer the course to others, and the likelihood that they would take another course like this were considerably lower than those of students in the flipped or regular classroom situations. The results of this study support the conclusion that a technology enhanced flipped classroom was both effective and scalable; it better facilitated learning than the simulation-based training and students found this approach to be more motivating in that it allowed for greater differentiation of instruction.  相似文献
