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 examined the use of form and function analogy object boxes to teach second graders (n = 21) animal adaptations. The study used a pretest–posttest design to examine animal adaptation content learned through focused analogy activities as compared with reading and Internet searches for information about adaptations of animals followed by making an informative puppet play. Students participated in six week‐long lesson sets, each addressing adaptations of two animals, which alternated between the two conditions. In the analogy condition, students matched cards explaining form and function analogies of animal body parts or homes to analogous manufactured items. They mapped analogies, thought of alternate manufactured items, and created new analogies. Students scored similarly on material to be taught through both conditions on the pretest, but made significantly higher posttest mean scores (76.1% analogy versus 57.2% traditional condition) with large effect size (partial η2 = 0.58) on animal adaptation content learned through the analogy activities. This study shows the usefulness of form and function analogies in teaching product innovations to second‐grade students, indicating that early childhood students are able to successfully engage in sophisticated analogy activities. Efficacy of the analogy activities was related to objects that focused attention, motivated, and gave concrete representations of concepts; to cards and graphic organizers for organization, connections, and memory; and to complex thinking activities that challenged students and promoted peer interaction.  相似文献

Repeated reading (RR) is a common fluency intervention, but recent studies comparing RR to continuous reading (CR; i.e., wide reading) found no significant differences in effects. This prompts the question of whether the mechanism that improves skills is repeatedly reading portions of connected text, or simply reading connected text. The current study examined the differential effectiveness of RR and CR for increasing oral reading fluency rate (ORF) and comprehension of 40 students in second and third grades, randomly assigned to receive the RR or CR intervention. Students in both conditions received a standardized amount of practice (dosage) in the form of number of words read during each intervention session. All but two participants increased their ORF and there were no significant differences between groups on posttest ORF or broad comprehension. Moreover, students with the highest pretest scores made slightly more growth regardless of condition. Students in the RR group demonstrated significantly higher comprehension of practiced passages and students in the CR condition reported significantly higher levels of intervention acceptability. Implications for reading fluency intervention research and practice are discussed.  相似文献

Experimentation is a complex problem-solving process. In biology lessons, experiments involve creative thinking and open discovery; however, they still require some degree of instructional guidance. The right balance between discovery learning and instructional guidance depends substantially on students’ prior knowledge. Students with low prior knowledge in particular might have difficulties with conducting and understanding experiments. Incremental scaffolds might be a valuable tool to meditate between pure discovery and strong guidance while simultaneously taking learners’ individual knowledge and skills into account. In the current study, we examined the effects of incremental scaffolds (IncSc), no scaffolds (NoSc), and worked-out examples (WoEx) on students’ knowledge acquisition while doing inquiry-based experimentation with a special focus on students with low prior knowledge. In a pre-posttest design, 193 students (Mage?=?13.02?±?0.81 years) participated in a four-hour teaching unit on animals’ overwintering strategies. In the pre- and posttest, we assessed the students’ conceptual and procedural knowledge. Our results partially confirmed our hypotheses: Regarding the conceptual and procedural knowledge of all students, incremental scaffolds showed no additional benefit regarding students’ knowledge in the posttest when compared to working with no scaffolds or worked-out examples. For the students with low prior knowledge, working with incremental scaffolds led to higher conceptual and procedural knowledge after the teaching unit than working with worked-out examples.  相似文献

This study evaluates the effects of an intervention aimed at improving representational flexibility in linear-function problems. Forty-nine students aged 13–16 participated in the study. A pretest–intervention–posttest design with an experimental and control group was used. At pretest, both groups solved a choice test, where they could freely select a table, a graph, or a formula, and three no-choice tests, where they used predetermined representations. Twenty-five students in the experimental group were exposed to the intervention, where they learnt to fine-tune their choices both to the task at hand and to their own characteristics as representational users. The control group was not exposed to any intervention. The posttest was similar to the choice pretest. A flexibility score was calculated per student based on Siegler and Lemaire’s score. At posttest, the experimental group became more flexible than the control group. The impact of increased flexibility on problem-solving accuracy and speed is discussed.  相似文献

High-quality professional development is needed to prepare teachers to help students learn how to conduct online academic research and meet Common Core State Standards for English Language Arts. This study created and evaluated a Web-based professional development program with five instructional modules designed to prepare middle-school teachers to teach their students nine strategies for conducting academic research online. The online professional development program was specifically created to help teachers implement the previously developed online SOAR Student Toolkit curriculum with all students in inclusive classrooms. Results of a 2015–2016 pilot study conducted with 13 teachers and 477 students in sixth to eighth grades indicated that most teachers perceived the professional development program to be of high quality and relevant in helping them teach online research skills to their students. Students significantly improved online research skills after learning from trained teachers (27 percentage points improvement, from 18% at pretest to 45% at posttest).  相似文献

Students who lack metacognitive skills can struggle with the learning process. To be effective learners, students should recognize what they know and what they do not know. This study examines the relationship between students’ perception of their knowledge and determined knowledge in an upper-level biology course utilizing a pre/posttest approach. Significant differences in students’ perception of their knowledge and their determined knowledge exist at the beginning (pretest) and end (posttest) of the course. Alignment between student perception and determined knowledge was significantly more accurate on the posttest compared with the pretest. Students whose determined knowledge was in the upper quartile had significantly better alignment between their perception and determined knowledge on the pre- and posttest than students in the lower quartile. No difference exists between how students perceived their knowledge between upper- and lower-quartile students. There was a significant difference in alignment of perception and determined knowledge between males and females on the posttest, with females being more accurate in their perception of knowledge. This study provides evidence of discrepancies that exist between what students perceive they know and what they actually know.  相似文献

This study investigates the effects and feasibility of an intervention for first-grade students at risk for reading difficulties or disabilities (RD). The intervention was provided by general education classroom teachers and consisted of 15 min whole-class comprehension lessons (Tier 1) and 30 min Tier 2 intervention sessions in word reading, comprehension, and text reading. First-grade teachers (n = 21), with 4–5 students at risk for reading difficulties and potential reading disability were randomly assigned to treatment or typical practice comparison conditions. Significant group differences were detected on all measures of word reading, decoding, and fluency. Effect sizes were educationally important for all measures of word reading, decoding, and reading comprehension; however, effects on standardized measures were smaller than those in prior studies with similar students in which intervention was typically provided outside the regular classroom. An exploratory analysis indicated that students at different parts of the pretest and posttest distributions responded more and less positively to the intervention, providing insights that may help guide future revisions. The study provides preliminary evidence of the intervention's promise for positively impacting student outcomes.  相似文献

We investigated students’ emotions as intervening variables between teaching methods, motivational and performance prerequisites, and outcomes. 144 students from German schools were assigned to two conditions. In one condition, students were prompted to develop multiple solutions for modelling problems that were missing information. In the other condition, students had to find one solution for modelling problems that were not missing information. Students’ interest and performance were measured before and after the 5-lesson teaching unit, and students’ enjoyment and boredom were measured during the teaching unit. The path analyses revealed: (1) Students who developed more solutions enjoyed their mathematics lessons more and were less bored than students in the other condition; (2) Enjoyment affected students’ interest and performance at posttest and mediated the effects of prompting them to find multiple solutions on interest at posttest; (3) Students’ enjoyment during learning mediated the effects of prior interest on interest at posttest.  相似文献

We designed an educational activity for undergraduate students and assessed how this newly-constructed activity promoted students’ argumentation skills, thereby fostering their epistemic beliefs. This argumentation-based learning activity involved digital concept mapping. A quasi-experimental design involved pretests and posttests that were administered to 52 research participants in a group and 61 participants in a control group. Students’ argumentation skills were qualitatively examined by analyzing the structure of their arguments before and after the activity. Their perceptions of the activity and epistemic belief types (from absolutism to evaluativism) were measured with the Epistemic Beliefs Scale and the Concept Mapping for Problem-Based Learning Scale. The designed activity evoked epistemic change toward evaluativism among the students who were enrolled in the activity, whereas nonsignificant results emerged for the control group. However, for both pretest and posttest, the highest score was for Absolutist, followed by Multiplist, and Evaluativist had the lowest mean. The technology-enabled concept-mapping tool supported the research group’s online argumentation design. This tool helped students mainly at the cognitive level to discern between the arguments and better learn the topic. These findings are interpreted in relation to student characteristics.

In this study, pretest and posttest achievement test data were collected for 67 children with learning disabilities assigned to one of four conditions: one period of resource room instruction per day; two periods of resource room instruction per day; consultative services combined with in-class instruction; and consultative services to classroom teachers. Analysis of pretest achievement measures indicated that students assigned to two periods of resource room per day differed significantly from the other groups and results from this group were analyzed separately. Students in the remaining three conditions made gains in standing relative to same-age peers from pretest to posttest. Students receiving a combination of consultation and direct services showed small, but significantly greater overall gains in achievement than did students placed in the resource room.  相似文献

Minimal evidence exists regarding the retrospective pretest’s effectiveness as a tool to obtain usable, indirect evidence of student learning in open admissions institutions. The researcher conducted this study to determine if a retrospective pretest more accurately detected a change in students’ knowledge compared to a conventional pretest–posttest. The researcher designed a 17‐item inventory covering course objectives, and students were randomly assigned to either a retrospective pretest (referred to as post‐then) or a conventional pretest–posttest group. Findings indicated that participants in the post‐then group reported a greater change in knowledge compared to the conventional group. This finding supported the use of the retrospective pretest as a tool for getting usable, indirect evidence of student learning. Future research needs to examine response effect, alternative ways of calculating treatment effect and the confounding influences of other perceptual variables.  相似文献

Educational researchers have indicated that although computer games have the potential to promote students’ motivation and engagement, the work on how to design effective games that fulfil educational purposes is still in its infancy. This study aimed to examine how integration of self-explanation into a computer game affected primary schoolers’ acquisition of light and shadow concepts. The participants were randomly assigned to either an experimental group or a control group and played a computer game with or without self-explanation prompts individually as a treatment. Students’ conceptual understanding was evaluated through a pretest and a posttest administered right after the treatment. The results revealed that by controlling the pretest scores, students who played the game with self-explanation features did not outperform those who played the game without any prompts in the posttest. Further analyses of the experimental group students’ responses to the self-explanation prompts also indicated that the students with more correct responses to the prompts did not perform better than those with lower accuracy rates. The deficits in the use of self-explanation prompts are identified, and possible improvements to enhance the function of self-explanation in educational games are proposed.  相似文献

A quasi-experimental research design was used to investigate the effectiveness of synthetic phonics in the development of early reading skills among struggling young English as a second language (ESL) readers in a rural school. The pretest and posttest, adapted from the Phonological Awareness Literacy Screening (PALS) for Preschool Students and Grades 1 to 3 tests, assessed children’s early reading skills. A semi-structured interview was used to gather information. The findings indicated that the performance of students in the experimental group in decoding was significantly higher in the posttest, where t(39) = 31.441, p < .00005. Likewise, in comprehension, the experimental group achieved significantly higher scores in the posttest, where t(39) = 15.322, p < .00005. There was a significant difference in the achievement between the two groups, where t(78) = 31.010, p < .00005. This indicates that synthetic phonics could be effective in developing early reading skills for struggling readers.  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

The present study aimed to assess the effect of two different types of digital technologies (computers and tablets) in early childhood students’ understanding of numbers. Three hundred and sixty-five children (mean age in months, M?=?62.0, SD?=?5.5) from 21 kindergarten classes were randomly assigned to two intervention groups and a business-as-usual control group. The interventions were conducted over 24 half-hour lessons. Data was collected during the 2013–2014 school year using a three-step research procedure. Students’ knowledge about numbers was assessed using the Test of Early Mathematics Ability-3 (TEMA-3). Findings were that (a) both experimental groups significantly outperformed the control group on the posttest, (b) the group that used tablet computers significantly outperformed the group that used personal computers on the posttest, and (c) there was no significant difference between genders on the posttest. Our findings support that computers and especially tablets, when combined with the use of developmentally appropriate software into the children’s daily routines, may provide a substantial contribution to early childhood students’ comprehension of numbers.  相似文献

In science education, dissections of animals are an integral part of teaching, but they often evoke negative emotions. We aimed at reducing negative emotions (anxiety, negative affect [NA]) and increasing positive affect (PA) and self-efficacy by an experimental intervention using a predissection video to instruct students about fish dissection. We compared this treatment with another group that watched a life history video about the fish. The participants were 135 students studying to become biology teachers. Seventy received the treatment with the dissection video, and 65 viewed the life history video. We applied a pre/posttest treatment-comparison design and used the Positive and Negative Affect Schedule (PANAS), the State–Trait–Anxiety Inventory for State (STAI-S), and a self-efficacy measure three times: before the lesson (pretest), after the film treatment (posttest 1), and after the dissection (posttest 2). The dissection film group scored higher in PA, NA, and state anxiety (STAI-S) after the dissection video treatment and higher in self-efficacy after the dissection. The life history group showed no differences between the pretest and posttest 1. The dissection film has clear benefits—increasing PA and self-efficacy—that come at the cost of higher NA and higher STAI-S.  相似文献

There is growing evidence that targeted instruction can improve diagram comprehension, yet one of the skills identified in the diagram comprehension literature—coordinating multiple representations—has rarely been directly taught to students and tested as a classroom intervention. We created a Coordinating Multiple Representation (CMR) intervention that was an addition to an intervention focused on Conventions of Diagrams (COD) and tested their joint effects on diagram comprehension for near transfer (uninstructed biology diagrams), far transfer (uninstructed geology diagrams), and content learning (biology knowledge). The comparison group received instruction using a previously validated intervention that focused exclusively on COD. Participants were 9th–10th grade biology students (N?=?158 from two schools), whose classes were randomly assigned to COD alone or COD?+?CMR conditions and studied with a pretest–posttest experimental design. Both groups showed significant growth in biology knowledge (d?=?.30–.53, for COD and COD?+?CMR, respectively) and biology diagram comprehension (d?=?.28–.57). Neither group showed far transfer. Analyses of student work products during the interventions suggest that gains were not simply due to the passage of time, because student effort was correlated with gains in both treatment groups. Directions for improving future CMR interventions are discussed.  相似文献
