The authors examined whether motivational goals influenced the participation and performance of low-achieving students during collaborative problem solving with a high-achieving partner. Thirty-five pairs of 4th- and 5th-grade students were randomly assigned a set of instructions designed to induce students to adopt a learning goal or a performance goal. The following day, the students were individually given a posttest on problems similar to those worked on collaboratively. The low-achieving students given learning-goal instructions performed better on the posttest problems and perceived their partner's competence as more similar to their own than did the low-achieving students given performance-goal instructions. No differences in overall amount or level of low achievers' participation during collaborative problem solving were observed. Implications of the findings for the use of peer learning in heterogeneous classrooms are discussed.  相似文献

This study explored third-grade elementary students' conceptions of nature of science (NOS) over the course of an entire school year as they participated in explicit-reflective science instruction. The Views of NOS-D (VNOS-D) was administered pre instruction, during mid-school year, and at the end of the school year to track growth in understanding over time. The Young Children's Views of Science was used to describe how students conversed about NOS among themselves. All science lessons were videotaped, student work collected, and a researcher log was maintained. Data were analyzed by a team of researchers who sorted the students into low-, medium-, and high-achieving levels of NOS understandings based on VNOS-D scores and classwork. Three representative students were selected as case studies to provide an in-depth picture of how instruction worked differentially and how understandings changed for the three levels of students. Three different learning trajectories were developed from the data describing the differences among understandings for the low-, medium-, and high-achieving students. The low-achieving student could discuss NOS ideas, the medium-achieving student discussed and wrote about NOS ideas, the high-achieving student discussed, wrote, and raised questions about NOS ideas.  相似文献

In this study we describe the social interactions of ability-grouped dyads as they constructed knowledge of balance concepts to elucidate the relationship between interactions and conceptual growth. The verbal and nonverbal behaviors of 30 fifth-grade students were recorded as they completed three activities related to balance. These student interactions were examined within a framework of social cognition. For each dyad, characteristics of ability-grouped dyads were identified. Results revealed that high-achieving students effectively used prior experiences, maintained focus on the learning task, and were able to manipulate the equipment effectively to construct knowledge. Low-achieving students exhibited off-task behavior, lacked a metacognitive framework for organizing the learning tasks, centered on irrelevant features of the equipment, and were unable to use language effectively to mediate learning. Within low-high student dyads, high-achieving students typically modeled thinking processes and strategies for manipulating equipment. In addition, they focused the low-achieving students on the components of the tasks while verbally monitoring their progress, thus enabling low students to identify the critical features necessary for concept construction. These results highlighted the differences that students have in the use of language and tools. Low students' inefficient use of tools has implications for the ways science teachers structure lessons and group students for laboratory work.  相似文献

Instructional design research promotes interactive and adaptive scaffolds as features of educational technology. Mathematics education research can guide elaborated fractions curricula to develop basic fraction concepts while challenging the natural number bias. Thus, we developed theory-grounded interactive material for learning fractions providing scaffolds in an eBook. Evaluating both, curriculum and scaffolds, we split 745 high-achieving and 260 low-achieving 6th graders into three groups: Scaffolded Curriculum group (using the eBook on iPads), Curriculum group (using a paper copy of our developed material), and Traditional group (using conventional textbooks). Generalized linear mixed models revealed diverse positive effects on the achievement of students in the experimental conditions: Results showed that high-achieving students did benefit from the curriculum, regardless of whether it was presented with or without scaffolds, while for low-achieving students using scaffolds was decisive. This suggests that interactive and adaptive scaffolds can support students in learning mathematical concepts, especially for low-achieving students.  相似文献

The present study investigated the differences of strategy use between low-, average-, and high-achieving students when solving different multiplication problems. Nineteen high-, 48 average-, and 17 low-achieving students participated in this study. All participants were asked to complete three different multiplication tests and to explain how they solved these problems. Results suggested that low achievers used incorrect operation strategies more frequently, indicating a lack of conceptual understanding of multiplication. High-achieving students demonstrated greater flexibility in problem-solving and were more accurate in performing direct retrieval or math algorithm strategies. Results were discussed about improving low achievers’ use of advanced strategies, enhancing their flexibility in choosing strategies and improving students’ accuracy in using direct retrieval or math algorithms.  相似文献

Meta-strategic Knowledge (MSK) is a sub-component of metacognition that is defined in the present study as general, explicit knowledge about thinking strategies. In the present study we shall focus on the control of variables thinking strategy. Following an earlier study (Zohar & Peled 2007) that showed considerable effects of explicit instruction of MSK in laboratory setting, this study explores whether these effects are preserved in authentic classroom situations. Participants were 119 8th grade students from 6 classes of a heterogeneous school. Equal numbers of low-achieving and high-achieving students were randomly assigned into experimental and control groups. The findings showed dramatic developments in students’ strategic and meta-strategic thinking following instruction. The effect of the treatment was preserved in delayed transfer tests. Our findings show that explicit teaching of MSK had a strong effect on low achieving students. The implications of the findings for learning and instruction are discussed.  相似文献

Abstract

This study examined the effect of schema-based instruction (SBI) on 7th-grade students’ mathematical problem-solving performance. SBI is an instructional intervention that emphasizes the role of mathematical structure in word problems and also provides students with a heuristic to self-monitor and aid problem solving. Using a pretest-intervention–posttest-retention test design, the study compared the learning outcomes for 1,163 students in 42 classrooms who were randomly assigned to treatment (SBI) or control condition. After 6 weeks of instruction, results of multilevel modeling indicated significant differences favoring the SBI condition in proportion problem solving involving ratios/rates and percents on an immediate posttest (g = 1.24) and on a 6-week retention test (g = 1.27). No significant difference between conditions was found for a test of transfer. These results demonstrate that SBI was more effective than students’ regular mathematics instruction.  相似文献

The present study evaluated the effectiveness of an instructional intervention (schema-based instruction, SBI) that was designed to meet the diverse needs of middle school students by addressing the research literatures from both special education and mathematics education. Specifically, SBI emphasizes the role of the mathematical structure of problems and also provides students with a heuristic to aid and self-monitor problem solving. Further, SBI addresses well-articulated problem solving strategies and supports flexible use of the strategies based on the problem situation. One hundred forty eight seventh-grade students and their teachers participated in a 10-day intervention on learning to solve ratio and proportion word problems, with classrooms randomly assigned to SBI or a control condition. Results suggested that students in SBI treatment classes outperformed students in control classes on a problem solving measure, both at posttest and on a delayed posttest administered 4 months later. However, the two groups’ performance was comparable on a state standardized mathematics achievement test.  相似文献

This retrospective study examined L1 achievement, intelligence, L2 aptitude, and L2 proficiency profiles of 208 students completing two years of high school L2 courses. A cluster analysis was performed to determine whether distinct cognitive and achievement profiles of more and less successful L2 learners would emerge. The results of nonhierarchical (k — means clustering) revealed three distinct cognitive and achievement profiles. Participants in the high-achieving cluster scored above average range generally on all L1 and L2 measures; students in the average-achieving cluster scored average range generally on all L1 and L2 measures; and those in the low-achieving cluster scored low to below average range generally on all measures except IQ. Findings suggest that students' level of achievement in L1 skills developed prior to L2 exposure is strongly related to and consistent with their L2 aptitude and proficiency, level of attainment in L2 is moderated by level of attainment in L1, and L2 learning runs along a continuum of learners with stronger to weaker language skills.  相似文献

This study assessed the effects of explicit teaching of metastrategic knowledge (MSK) on gains of low-achieving (LA) and high-achieving (HA) 5th grade students (N = 41). Gains in reasoning scores of students from the Experimental group (compared to students from the control group) were obtained on the strategic and on the metastrategic level. Gains were preserved in near and far transfer tasks immediately after the end of instruction and 3 months later. Explicit teaching of MSK affected both LA and HA students, but it was extremely valuable for LA students who required a longer period than HA students to reach their top score.  相似文献

The purpose of this study was to explore the role of students' use of writing strategies in light of their English writing achievements in Taiwan. This research used a cognitive approach to examine the process of writing. Forty student writers (including 20 low and 20 high achievers) in Taiwan participated in this study. Strategies used for writing by high and low achievers as revealed by a concurrent think-aloud protocol and immediate retrospective interviews with students were investigated, analysed, and compared. Results indicated that compared to low-achieving student writers, high-achieving student writers were more aware of and focused more on formulating their position statement in planning, generating text, and revising and editing their text, such as changing the meaning and fixing grammatical and spelling errors during their review. The findings are discussed in light of writing strategies and implications for writing pedagogy and teacher education.  相似文献

Abstract

The authors investigated the influence of engaging in a problem-based learning unit on middle school students' epistemic beliefs, and how such students' epistemic beliefs and approaches to argumentation within and outside of their small groups related. Data sources include state science achievement test scores, epistemic beliefs pre- and posttests, videotaped class sessions, retrospective interviews, and pre- and post-cognitive interviews. Quantitative data were collected and analyzed from 59 students, while the qualitative subsample consisted of 15 students. Engaging in problem-based learning led to a significant effect on students' epistemic beliefs. The effect was of a large magnitude among high-achieving students, of a small magnitude among average-achieving students, and of a small negative magnitude among lower-achieving students. Students employed different approaches to generating and evaluating arguments in different ecosystems, including as small groups and in discussions with the teacher.  相似文献

The results of two experiments demonstrate that preservice teachers made biased school-placement recommendations depending on student's ethnicity, which on average penalized students from an ethnic minority. Moreover, additional information that was supposed to disconfirm ethnic stereotypes (religious affiliation in Experiment 1, number of missed school days in Experiment 2) led to more high-track recommendations for low-achieving minority students and to fewer high-track recommendations for high-achieving minority students. Conversely, stereotype-disconfirming information exerted little or no influence on the recommendations for high-achieving native students but worsened recommendations for low-achieving students. The results were interpreted as being based either on subtyping (predominantly for minority Turkish students) or subgrouping (predominantly for majority German students) of ethnic stereotypes.  相似文献

This study investigated the hypothesis that the academic achievement of Mexican-American students could be explained in part by a conflict in the values of Mexican-American and Anglo-American cultures. Mexican-American and Anglo-American students, their parents, and teachers reported their adherence to traditional school values and their view of the importance of field independent behaviors to success in school. Differences in perceptions and values were observed between cultures and between high-achieving and low-achieving students. The greatest attitudinal differences were observed when high-achieving students were compared with parents and teachers. High-achieving students were less traditional in their attitudes toward school and more field independent than were parents, teachers, and low-achieving students.  相似文献

Background: This study deals with the application of concept mapping to the teaching and learning of a science topic with secondary school students in Germany.

Purpose: The main research questions were: (1) Do different teaching approaches affect concept map structure or students' learning success? (2) Is the structure of concept maps influenced by gender? (3) Is the concept map structure a reliable indicator of students' learning success?

Sample: One hundred and forty-nine high-achieving 5th-grade students from four German secondary schools participated in the study. The average age of participants was 10½ years. Gender distribution was balanced. Students produced concept maps working in small, single-sex groups.

Design and methods: There were two teaching approaches used: one based upon teacher-centred instruction and one consisting of student-centred learning. Both were followed by a concept-mapping phase. Student groups experienced either one or the other teaching approach. Concept map structures were analysed using of the method of Kinchin, Hay and Adams. We defined three different possible types of concept map structure: spokes, chains and nets. Furthermore, for assessing a student's short- and longer-term learning success, we constructed a multiple-choice knowledge test applied in a pre-, post-, retention-test design. Parametric tests, such as MANOVA, one-way ANOVA and t-tests were used to identify any differences in gender, teaching approach, number of nets per concept map and their interactions.

Results: Type of teaching approach had an effect on concept map structure but not on students' longer-term learning success. Students of the teacher-centred approach produced more net structures than those students who participated in the hands-on instruction. Subsequent analyses showed in total more net structures for female groups. The interaction of gender and number of nets per concept map showed a significant effect on students' longer-term learning success.

Conclusion: The study suggests that Kinchin's classification scheme for assessing concept map quality may be a good indicator of students' learning success when applied in combination with a knowledge test.  相似文献

Many students find math difficult, but those who are intrinsically motivated learn and do well even when they face obstacles. Here, we examine an environmental factor that might affect students' intrinsic motivation in math: namely, teachers' beliefs about success in math. Do teachers perceive elementary school math as a domain that requires an innate ability, and does this belief relate to students' intrinsic motivation in math? Our study explored these questions in a sample of 830 German fourth graders and their 56 teachers. Teachers reported stronger beliefs in the role of innate ability for math than for German language arts. In addition, the more teachers believed that math requires innate ability, the lower was the intrinsic motivation of their low-achieving students. These results suggest that teachers’ beliefs that math success depends on innate ability may be an important obstacle to creating a classroom atmosphere that fosters engagement and learning for all students.  相似文献

A prerequisite for correcting ineffective education is the examination of research on the learning environments of successful schools and the conditions and processes that enable quality outcomes. The research described in this article supports the Talent Development philosophy, which rejects deficit-based "talent sorting" models of schooling and promotes widespread academic success in appropriately supportive environments. The study delineates the common organizational characteristics of schools in low-income areas that defy the odds by producing high numbers of high-achieving African American students. Specifically, it explores how urban elementary schools that successfully serve primarily low-income African American students are configured to support students' academic and personal growth.

Participating schools were selected based on test scores evidencing their students' sustained mathematics and reading achievement. The data for the analysis was obtained from questionnaires mailed to the schools' principals. Patterns in the data and discernable trends across schools are described.  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 article reports a quasi-experimental study on the effects of multimedia teaching and learning in English Literature – a subject which places high cognitive load on students. A large-scale study was conducted in 4 high-achieving secondary schools to examine the differences made to students' learning and performance by the use of multimedia and to relate this to different kinds of multimedia. Statistical significance and effect size calculations indicated that the equivalent of one grade level in General Certificate of Secondary Education (GCSE) was associated with the use of advanced and integrated multimedia, and that this was stronger than the effects of schools and sex of the students. It was found that advanced multimedia software eased cognitive overload, particularly in the area of intrinsic cognitive load. Limitations of the study are drawn, including the needs to examine process variables and learner-related variables. Conclusions and implications for further research and for enhancing teaching and learning with multimedia are made.  相似文献
