ABSTRACT

Many science curricula and standards emphasise that students should learn both scientific knowledge and the skills associated with the construction of this knowledge. One way to achieve this goal is to use inquiry-learning activities that embed the use of science process skills. We investigated the influence of scientific reasoning skills (i.e. conceptual and procedural knowledge of the control-of-variables strategy) on students’ conceptual learning gains in physics during an inquiry-learning activity. Eighth graders (n?=?189) answered research questions about variables that influence the force of electromagnets and the brightness of light bulbs by designing, running, and interpreting experiments. We measured knowledge of electricity and electromagnets, scientific reasoning skills, and cognitive skills (analogical reasoning and reading ability). Using structural equation modelling we found no direct effects of cognitive skills on students’ content knowledge learning gains; however, there were direct effects of scientific reasoning skills on content knowledge learning gains. Our results show that cognitive skills are not sufficient; students require specific scientific reasoning skills to learn science content from inquiry activities. Furthermore, our findings illustrate that what students learn during guided inquiry activities becomes visible when we examine both the skills used during inquiry learning and the process of knowledge construction. The implications of these findings for science teaching and research are discussed.  相似文献

Previous research studies examining the effects of graphic organizers on reading comprehension for students with learning disabilities (LD) are reviewed. An extensive search of the professional literature between 1963 and June 2001 yielded a total of 21 group design intervention studies that met the criteria for inclusion in the synthesis. Using graphic organizers (i.e., semantic organizers, framed outlines, cognitive maps with and without a mnemonic) was associated with improved reading comprehension overall for students with LD. Compared to standardized reading measures, researcher-developed comprehension measures were associated with higher effect sizes. Initial gains demonstrated when using graphic organizers were not revealed during later comprehension tasks or on new comprehension tasks.  相似文献

This study examines the effect of teacher reasoning level (i.e., concrete versus formal) and teaching style preference (i.e., inquiry vs. expository) on improvement in student reasoning ability. A random sample of fourth and seventh grade teachers and their students were selected to participate over one school year. Students completed a reasoning test in the early fall and late spring. Teachers completed two instruments in the Spring, a reasoning test and a teaching style preference questionnaire. Students of concrete operational teachers showed greater gains in reasoning ability than students of formal operational teachers while students of inquiry teachers showed slightly greater gains than students of expository teachers. Possible explanations are discussed as are suggestions for future research.  相似文献

Serious educational gameplay continues to gain traction in K-12 educational settings, as access to novel technologies increases. Increased access to computers and other devices has shifted the landscape of the classroom, increasing students' screen-time, as technology infused lessons replace other learning experiences. Amid this context, our research team created a serious educational game (SEG) designed for elementary science learners. Previous studies have linked serious gameplay to learning gains and changes in attitudes, yet the rigor of the studies often underwhelms, as the studies lack an adequate sample size, detailed student data, or quality comparison groups. These limitations are compounded in the study of science learning in elementary schools, due to structural difficulties and student variability that impede the implementation of this type of experimentation. This research attends to this knowledge gap, as our team conducted two quasi-experimental studies to explore the learning gains associated with Virtual Vet, a SEG designed to address the fundamental science concepts associated with the human body systems and the subsequent effect of diabetes and obesity related illnesses on the given body systems. In Study 1, students (n = 232) were randomly assigned to play Virtual Vet or participate in guided inquiry lessons that addressed the same objectives. Our study found that students in the game condition outperformed the non-game condition. Based on this finding, we designed Study 2 to compare learning outcomes associated with two conditions: students play only Virtual Vet or students play Virtual Vet and they participate in the guided inquiry activities, which doubled the instructional time for this group. Students (n = 166) were assigned to one of the conditions and we found no significant increase in learning gains for the students who participated in both activities. These results indicate that well-designed SEGs powerfully facilitate and support science learning in elementary settings.  相似文献

Although the effects of open inquiry vs. more didactic approaches have been studied extensively, the effects of different types of inquiry have not received as much attention. We examined the effects of guided vs. structured inquiry on secondary students' learning of science. Students from three schools in north-eastern Thailand participated (N?=?239, Grades 7 and 10). Two classes in each school were randomly assigned to either the guided or the structured-inquiry condition. Students had a total of 14–15 hours of instructions in each condition. The dependent measures were science content knowledge, science process skills, scientific attitudes, and self-perceived stress. In comparison to the structured-inquiry condition, students in the guided-inquiry condition showed greater improvement in both science content knowledge and science process skills. For scientific attitudes and stress, students in one school benefited from guided inquiry much more than they did from structured inquiry. Findings were explained in terms of differences in the degree to which students engaged effortfully with the teaching material.  相似文献

Two studies examined response to varying amounts of time in reading intervention for two cohorts of first-grade students demonstrating low levels of reading after previous intervention. Students were assigned to one of three groups that received (a) a single dose of intervention, (b) a double dose of intervention, or (c) no intervention. Examination of individual student response to intervention indicated that more students in the treatment groups demonstrated accelerated learning over time than students in the comparison condition. Students' responses to the single-dose and double-dose interventions were similar over time. Students in all conditions demonstrated particular difficulties with gains in reading fluency. Implications for future research and practice within response to intervention models are provided.  相似文献

This study examined the relationship between cognitive abilities and math achievement within a sample of college students with learning disabilities (LD). The cognitive abilities were seven areas identified by Stratum II of the Cattell-Horn-Carroll (CHC) theory of cognitive abilities, in addition to the eighth area of Working Memory. Math performance was assessed via math calculation and math reasoning tasks. Instruments include the Woodcock-Johnson III Tests of Cognitive Abilities and Tests of Achievement. Participants were 158 college students with a diagnosed LD in math. Multiple regression analyses found that Processing Speed and Working Memory were related to Math Calculation scores and that Comprehension-Knowledge, Fluid Reasoning, and Working Memory were related to Math Reasoning. Implications for the assessment of math LD in the college populations are discussed.  相似文献

We transformed our first-year curriculum in biology with a new course, Biological Inquiry, in which >50% of all incoming, first-year students enroll. The course replaced a traditional, content-driven course that relied on outdated approaches to teaching and learning. We diversified pedagogical practices by adopting guided inquiry in class and in labs, which are devoted to building authentic research skills through open-ended experiments. Students develop core biological knowledge, from the ecosystem to molecular level, and core skills through regular practice in hypothesis testing, reading primary literature, analyzing data, interpreting results, writing in disciplinary style, and working in teams. Assignments and exams require higher-order cognitive processes, and students build new knowledge and skills through investigation of real-world problems (e.g., malaria), which engages students’ interest. Evidence from direct and indirect assessment has guided continuous course revision and has revealed that compared with the course it replaced, Biological Inquiry produces significant learning gains in all targeted areas. It also retains 94% of students (both BA and BS track) compared with 79% in the majors-only course it replaced. The project has had broad impact across the entire college and reflects the input of numerous constituencies and close collaboration among biology professors and students.  相似文献

Students with learning disabilities (LD) experience pervasive academic deficits requiring extensive academic intervention; however, they may also engage in problem behaviors that adversely affect teaching and learning, thus lessening the potential impact of specialized instruction and supports. The learning deficits of students with LD are prevalent in the extant research, but behavioral needs appear to receive less attention. The authors report the results of a systematic review investigating the evidence‐base for function‐based interventions for students with LD using the What Works Clearinghouse (WWC) criteria for evaluating single‐case studies. Fourteen studies with 17 participants met inclusion criteria, with the majority occurring in elementary settings. Although interventions tended to be effective, few included maintenance and generalization measures. Because of the small number of studies (n = 4) that met WWC design and effectiveness standards, the authors conclude that function‐based interventions, although promising, cannot currently be considered an evidence‐based practice for students with LD. Implications for practice, areas for future research, and study limitations are reported.  相似文献

The two case studies reported in this article contribute to a better understanding of how inquiry tasks and activities are employed as resourceful means for learning in higher professional education. An observation-based approach was used to explore characteristics of and challenges in students’ participation in collaborative inquiry activities in two first-year introductory courses in teacher and computer engineering education. The findings highlight that the students’ activities varied with regard to focus and structure and were shaped by the types of inquiry tasks, i.e. case analysis and project-based work, by how the inquiry process was guided and supported and the way the domain-specific knowledge resources and practices were introduced. An exploratory strategy and rather confined use of resources characterised the teacher education students’ inquiry, while collaborative programming, a trial-and-error approach and extensive use of external resources that of the engineering education students’. For the teacher students, the main challenge was to construct meaning of conceptual knowledge and to integrate different forms of knowledge as a lens for analysing practice. The computer engineering students experienced challenges with unpacking the underlying principles and knowledge black-boxed in the widely available resources. The article suggests that future research and curriculum designs should depart from a more refined understanding of inquiry as a learning means, by connecting inquiry activities to the specific knowledge domains, the type of tasks most suited to explore each of this domains and the challenges that may arise for students.  相似文献

Fluent reading, often defined as speed and accuracy, is an important skill for all readers to develop. Students with learning disabilities (LD) often struggle to read fluently, leading to difficulties in reading comprehension. Despite recent attention to reading fluency and ways to improve fluency, it is not clear which features of interventions that are designed to enhance fluency are beneficial for the most struggling readers. The purpose of this study is to synthesize research on interventions that are designed primarily to build reading fluency for students with LD. The search yielded 24 published and unpublished studies that reported findings on intervention features, including repeated reading with and without a model, sustained reading, number of repetitions, text difficulty, and specific improvement criteria. Our findings suggest that effective interventions for building fluency include an explicit model of fluent reading, multiple opportunities to repeatedly read familiar text independently and with corrective feedback, and established performance criteria for increasing text difficulty.  相似文献

This article presents a framework and methodology for designing learning goals targeted at what students need to know and be able to do in order to attain high levels of literacy and achievement in three disciplinary areas—literature, science, and history. For each discipline, a team of researchers, teachers, and specialists in that discipline engaged in conceptual meta-analysis of theory and research on the reading, reasoning, and inquiry practices exhibited by disciplinary experts as contrasted with novices. Each team identified discipline-specific clusters of types of knowledge. Across teams, the clusters for each discipline were grouped into 5 higher order categories of core constructs: (a) epistemology; (b) inquiry practices/strategies of reasoning; (c) overarching concepts, themes, and frameworks; (d) forms of information representation/types of texts; and (e) discourse and language structures. The substance of the clusters gave rise to discipline-specific goals and tasks involved in reading across multiple texts, as well as reading, reasoning, and argumentation practices tailored to discipline-specific criteria for evidence-based knowledge claims. The framework of constructs and processes provides a valuable tool for researchers and classroom teachers' (re)conceptualizations of literacy and argumentation learning goals in their specific disciplines.  相似文献

The objectives of this study were to (1) evaluate group differences in specific arithmetic competencies among students with various types of learning difficulties (LD) and (2) to examine the influence of attention behaviors on possible group differences. Participants were a community sample of 291 third‐ and fourth‐grade students with reading difficulties (RD) and/or math difficulties (MD), or with no LD (51 MD, 66 RD, 89 MD + RD, and 85 No LD students). Students were administered computerized measures of cognitive addition, subtraction, and estimation (accuracy and response times), as well as other measures. Groups were compared with and without covariation for behavioral inattention and their interactions. Small sums addition, thought to reflect retrieval processes, estimation accuracy, and number knowledge, did not show differences between MD and MD + RD students, although both showed lower performance than the RD and No LD groups. Attention behavior had a variable impact, most typically making group differences larger, but did not alter the general pattern of group differences, except in the case of estimation.  相似文献

Abstract The purpose of this article is to provide an overview of research‐based interventions that incorporate self‐regulation strategies to improve mathematics performance of students with learning disabilities (LD). Self‐regulation is a metacognitive function essential to academic success. Students with LD are notoriously poor at self‐regulation and must be taught explicitly to monitor and control their cognitive activities as they engage in academic tasks such as mathematical problem solving. This article describes intervention studies that use self‐regulation strategies to improve mathematics performance of students with LD at the elementary, middle, and secondary school levels. Several techniques to facilitate effective implementation of self‐regulation instruction in the classroom are presented.  相似文献

Previous research studies examining the effects of spelling and reading interventions on the spelling outcomes of students with learning disabilities (LD) are synthesized. An extensive search of the professional literature between 1995 and 2003 yielded a total of 19 intervention studies that provided spelling and reading interventions to students with LD and measured spelling outcomes. Findings revealed that spelling outcomes were consistently improved following spelling interventions that included explicit instruction with multiple practice opportunities and immediate corrective feedback after the word was misspelled. Furthermore, evidence from spelling interventions that employed assistive technology aimed at spelling in written compositions indicated positive effects on spelling outcomes.  相似文献

Operation ARA (Acquiring Research Acumen) is a computerized learning game that teaches critical thinking and scientific reasoning. It is a valuable learning tool that utilizes principles from the science of learning and serious computer games. Students learn the skills of scientific reasoning by engaging in interactive dialogs with avatars. They are tutored by avatars with tutoring sessions that vary depending on how well students have responded to questions about the material they are learning. Students also play a jeopardy-like game against a feisty avatar to identify flaws in research and then generate their own questions to determine the quality of different types of research. The research examples are taken from psychology, biology, and chemistry to help students transfer the thinking skills across domains of knowledge. Early results show encouraging learning gains.  相似文献

In this investigation, fifth‐ and sixth‐grade children (N= 289) completed a measure to assess aspects of their relationships with teachers and bonds with schools. Children and teachers also completed measures related to children's social and emotional adjustment. Analyses of responses to these measures indicated that students with disabilities had greater dissatisfaction with their relationships with teachers, poorer bonds with school, and perceived higher school danger than did students without disabilities. Comparisons involving students who were receiving services for emotional disturbance (ED), learning disabilities (LD), mild mental retardation (MMR), other health impairments (OHI), and no disabilities indicated that students with ED and students with MMR had poorer affiliation with teachers and greater dissatisfaction with teachers than students without disabilities. Students with ED also had poorer bonds with school than did students without disabilities. Students with LD and students with MMR had significantly higher ratings of perceived school danger than did students without disabilities. Results of correlational analyses indicated that student‐teacher relationship and school bonding variables were associated with social and emotional adjustment variables for students with and without disabilities. © 2001 John Wiley & Sons, Inc.  相似文献

This study investigates the Chinese reading patterns of students with learning disabilities (LD). The performances of students with LD in reading the three categories of Chinese characters were particularly analysed: regular, irregular, and pseudo-characters. Fifty-three students with LD in reading and 44 students without LD of Year 4 were selected from five Hong Kong primary schools. Their abilities for reading Chinese characters were measured using Rasch analysis. Both types of students found regular characters as the easiest to read. Students without LD showed better performance in reading irregular characters than pseudo-characters, whereas students with LD exhibited no significant performance difference in reading these two categories. The implication of these results is that the students without LD might rely on using the orthographic processing than that of phonological processing to read. On the other hand, students with LD might not have the preference of using the orthographic processing.  相似文献

Designing and conducting sound and informative experiments is an important aspect of inquiry learning. Students, however, often design experiments that do not allow them to reach conclusions. Considering the difficulties students experience with the process of designing experiments, additional guidance in the form of an Experiment Design Tool (EDT) was developed, together with reflection questions. In this study, 147 pre-university students worked in an online inquiry learning environment on buoyancy and Archimedes’ principle. Students were randomly assigned to one of three conditions, each of which contained a different version of the EDT. Since students’ prior knowledge has been found to influence the amount and type of guidance they need, the versions of the tool differed with respect to the level of guidance provided. A pre- and post-test were administered to assess students’ conceptual knowledge. No overall differences between conditions were found. In a subsequent analysis, students were classified as either low, low-intermediate-, high-intermediate, or high prior knowledge students. For Archimedes’ principle we found that low-intermediate prior knowledge students gained significantly more conceptual knowledge than low prior knowledge students in the fully guided condition. It is hypothesised that students need at least some prior knowledge in order to fully benefit from the guidance offered.  相似文献

A student teacher placed at a school with a high English Language Learner population used mini iPads, and an application called Nearpod, during guided reading instruction. Groups of students in a fourth grade classroom used this application. The students and the teacher were interviewed to determine the benefits and challenges of this approach. An analysis of data revealed that all of the students found this type of guided reading to be beneficial and motivating in learning the content presented through the application. Students also explained how they could transfer the knowledge gained into their independent work. The teacher discussed how it improved organization in a guided reading group, but how careful consideration and planning must be done to ensure the technology will work properly during guided reading. It is recommended that the Nearpod application be used in guided reading lessons because of its user-friendliness, ability to engage students, and monitor their progress.  相似文献
