This study tested the effects of an entrepreneurship education intervention, the New Youth Entrepreneur curriculum, on lower socioeconomic black high-school students' knowledge of basic and advanced concepts in entrepreneurship. Ninety-five high school sophomores (over 85% black) from a lower socioeconomic neighborhood made up the sample for the experimental design: 51 in the treatment group and 44 in the control group. The two instruments used measured participants' knowledge of basic entrepreneurship concepts and higher cognitive levels of entrepreneurship learning, including comprehension, application, and analysis. The treatment group experienced the New Youth Entrepreneur (NYE) curriculum for one period a day for a semester, while the control group was exposed to basic entrepreneurship concepts at an awareness level as part of a general business education course. It was predicted and found that the treatment group significantly outperformed the control group on all dimensions of entrepreneurship tested. The study results confirm that appropriate curricular innovation can significantly influence the acquisition of entrepreneurship concepts and skills by lower socioeconomic black students. They also confirm that these same students can even be energized to the point of moving from opportunity recognition to initial business implementation. 相似文献

This article presents two longitudinal studies that investigated expertise reversal effects in journal writing. In Experiment
1, students wrote regular journal entries over a whole term. The experimental group received a combination of cognitive and
metacognitive prompts. The control group received no prompts. In the first half of the term, the experimental group applied
more cognitive and metacognitive strategies in their journals and showed higher learning outcomes than the control group.
Towards the end of the term, the amount of cognitive and metacognitive strategies elicited by the experimental group decreased
while the number of cognitive strategies applied by the control group increased. Accordingly, the experimental group lost
its superiority on learning outcomes. In order to avoid these negative long-term effects of prompts, a gradual and adaptive
fading-out of the prompts was introduced in the experimental group in Experiment 2 while a control group received permanent
prompts. The results showed that, over the course of the term, the fading group applied increasingly more cognitive strategies
while the control group applied fewer and fewer cognitive strategies. Accordingly, at the end of the term, the permanent prompts
group showed substantially lower learning outcomes than the fading group. Together, these results provide evidence for an
expertise reversal effect in writing-to-learn. The more the students became skilled in journal writing and internalized the
desired strategies, the more the external guidance by prompts became a redundant stimulus that interfered with the students’
internal tendency to apply the strategies and, thus, induced extraneous cognitive load. Accordingly, a gradual fading-out
of the prompts in line with the learners’ growing competencies proved to be effective in mitigating the negative side-effects
of the provided instructional support. 相似文献

ABSTRACT This article reports on an intervention study into the effects of a training in the use of social and cognitive strategies on the learning outcomes of students in secondary mathematics education. Special attention is given to differential effects for high‐ and low‐achieving students. The focus on differential effects is derived from studies into learning in small co‐operative groups, and from the results of meta‐analyses into the effects of training in learning strategies. From these studies it can be concluded that in general such programs contribute to learning. However, it seems that low‐achieving students are unable to benefit from interventions of the kind investigated (i.e., co‐operative learning and training in learning strategies). The main question is whether it is possible to design an instructional program from which all students benefit, and from which the low‐achieving students profit more than their counterparts in the control‐program. In the present study three instructional programs for co‐operative learning were compared: (i) an experimental program with special instruction in the use of social strategies; (ii) an experimental program with special instruction in the use of cognitive strategies; and (iii) a control program without training in either cognitive or social strategies. The programs were identical with respect to mathematical content and general instructional settings (a combination of whole‐class instruction, working in co‐operative groups and individual work). The experiment addressed the following research question: what are the general and differential effects of a training in the use of social and cognitive strategies on the results of learning in secondary mathematics? The research was conducted in two schools for secondary education in a total of 21 classes, involving a total of 511 students. The design was a pretest‐posttest control group design, using two experimental groups and one control group. The data were analysed from a multi‐level perspective. The outcomes of the investigation clearly show the effects of the intervention. Teaching cognitive and social strategies has the expected, positive effects. In addition to this main effect, a compensatory effect for the low‐achieving students was found. The low‐achieving students in the experimental conditions outperformed their counterparts in the control group. 相似文献

The attributes of a commercial microcomputer software package were evaluated as a supplement to traditional instruction in general chemistry classes in a suburban public high school. During a unit of study of writing and naming formulas and balancing chemical equations, the experimental group received reinforcement via microcomputer while the control group used parallel worksheet exercises over a period of three weeks for concept reinforcement. Analysis of achievement scores indicated significantly higher scores among the students in the control group. In order to ascertain any possible differential effects favoring either method for students at varying cognitive development levels, the study investigated the relationship between treatment (CAI versus worksheet) and development stage; no significant interactions were discovered. 相似文献

The main objective of this study was to evaluate the effect of teaching experiments within a dialectic-constructivist framework based on the following considerations: (a) Cognitive conflicts used in the teaching experiments must be based on problem-solving strategies that students find relatively convincing: (b) after having generated a cognitive conflict, it is essential that the students be provided with an experience that could facilitate the resolution of the conflict; and (c) the teaching strategy developed is used by an interactive constructivist approach within an intact classroom. The study was based on two sections of freshman students who had registered for Chemistry I at the Universidad de Oriente, Venezuela. One of the sections was randomly designated as the control group and the other as the experimental group. To introduce cognitive conflict, the experimental group was exposed to two teaching experiments dealing with stoichiometry problems based on the concept of limiting reagent. Students in the control group were exposed to the same problems—however, without the cognitive conflict teaching experiments format. To evaluate the effect of the teaching experiments, both groups were evaluated on five different problems at different intervals during the semester, referred to as posttests. All posttests formed part of the regular evaluation of the students. Results obtained show the advantage of the experimental group on four of the posttests. It is concluded that the experimental treatment was effective in improving performance on the immediate posttests. It was observed that some students protect their core belief [see Lakatos, I. (1970). Falsification and the methodology of scientific research programmes. In I. Lakatos & A. Musgrave (Eds.), Criticism and the growth of knowledge (pp. 91–196). Cambridge: Cambridge University Press] in stoichiometry (establishing equivalent relations between different elements or compounds) by ignoring the conflicting data, just as conflicting (anomalous) data do not necessarily convince a scientist to abandon a particular theory. 相似文献

Abstract This study aimed to evaluate the impact of the “I Found a Solution” computer‐assisted social skills intervention program on students with mild mental retardation. Teachers randomly divided students from two Israeli special schools (58 males, 29 females; aged 10.6 to 17.11 years) into an experimental and a control group. Teachers trained the experimental group using a social skills package including computerized social conflict scenarios and adventure games, group discussions, and homework tasks. Within the same time frame, teachers trained the control group to use various academic computer software programs. Following the intervention process, the research team collected information on students' self‐reported social skills and teachers' ratings of the students' adaptive classroom behavior. The experimental group performed significantly better than controls on posttest criteria. Teachers rated trained students as demonstrating better task orientation and less aggression and behavior difficulties. On subjective self‐reports, trained students reported more cooperation and assertion than the control group, but self‐control and empathy measures did not differentiate between groups. The use of a naturalistic mini‐environment for experimenting and rehearsing effective social strategies appears promising but requires further exploration. 相似文献

In this study, the effects of a form of cooperative group instruction (Student Teams Achievement Divisions) on student motivation and achievement in a high school geometry class were examined. Eighty students were randomly assigned to either a control group receiving traditional instruction or one of two treatment groups receiving cooperative learning instruction. Geometry achievement was assessed using scores from the IOWA Test of Basic Skills and teacher-made exams. An 83-item questionnaire was used as a pretest, posttest, and post-posttest assessment of efficacy, intrinsic valuing, goal orientation, and cognitive processing. Students in the cooperative treatment groups exhibited significantly greater gains than the control group in geometry achievement, efficacy, intrinsic valuing of geometry, learning goal orientation, and reported uses of deep processing strategies. The implications for cooperative group structures and motivation theory are discussed. 相似文献

This study investigated the impact of taking photos using mobile phones on the English phrase-learning performance of English as a second-language learners. A total of 116 students enrolled in a college in Central Taiwan participated in this study. The participants were divided randomly into two groups: a control group and an experimental group (EG). The control group was assigned an online phrase-reading activity for the purpose of phrase learning, whereas the EG was instructed to engage in phrase learning by taking photos using their mobile phones. The study primarily investigated the participants' daily encounters with newly acquired phrases through the use of photos taken using mobile phones, which were associated with the sentences they constructed. The results of the study indicated that the students in the EG significantly outperformed the control students on the delayed posttest, and the EG exhibited a significantly higher level of perception toward the phrase-learning activities compared with that of the control group. 相似文献

The aim of the present study was to investigate whether university students can adjust their study strategies to meet the cognitive demands of testing; a metacognitive self‐regulatory skill. One hundred and fifty undergraduates attended three lectures as part of a course on the psychology of individual differences. These participants were then assigned randomly to each of two groups. In the first group, the participants were instructed to study for a test that required deep‐level cognitive processing. In the second group, the participants were instructed to study for a test that required surface‐level cognitive processing. Results of the study showed that university students do adjust their study strategies so that they are in line with the cognitive processing demands of testing. It was also found that study strategies mediated the relationship between the type of test items expected and the test performance. 相似文献

Online video-based learning has been increasingly used in educational settings. However, students usually do not have enough cognitive capacity and metacognition skills to diagnose and record their attention status during learning tasks by themselves. This study thus presents an attention-based video lecture review mechanism (AVLRM) that can generate video segments for review based on students’ sustained attention status, as determined using brainwave signal detection technology. A quasi-experiment nonequivalent control group design was utilized to divide 55 participants from two classes of an elementary school in New Taipei City, Taiwan, into two groups. One class was randomly assigned to the experimental group, and used video lectures with the AVLRM support for learning. The other class was assigned to the control group, and used video lectures with autonomous review for learning. Analytical results indicate that students in the experimental group exhibited significantly better review effectiveness than did the control group, and this difference was especially marked for students who had a low attention level, were field-dependent, or were female. The findings show that AVLRM based on brainwave signal detection technology can precisely identify video segments that are more useful for effective review than those picked by student themselves. This study contributes to the design of learning tools that aim to support independent learning and effective review in online or video-based learning environments. 相似文献

This study aimed at investigating differential effects between group counselling and group guidance in conducting a ‘Coping
with Stress Training Program’ for 24 Turkish university students. The dependent variables were coping with stress, irrational
beliefs and optimism. A 3 × 2 design (treatment sequence by repeated measures) was applied. As a result of the treatment no
significant difference was observed between the two experimental groups in any of the variables tested in the study; however,
both experimental groups differed significantly from a control group in respect to coping with stress. With regard to the
within-group comparisons, irrational belief tendencies in both experimental groups decreased significantly, while the level
of optimism of the counselling group and the problem-focused stress coping tendencies of the guidance group increased significantly.
Based on the findings, it was considered that the program for developing coping skills for stress might best be implemented
in a group guidance format especially in Turkey where there are limited physical resources, a low number of staff to run programs
and a high number of students in need of help. 相似文献

The present study compares the effects of the cooperative jigsaw II method and traditional teacher-centred teaching method on improving vocabulary knowledge and active–passive voice in English as a foreign language for engineering students and the students' attitudes towards learning English. Jigsaw is a cooperative learning model that involves small groups of 5–6 students teaching each other subject matter with success dependent upon student cooperation. Sixty-six engineering students participated in the study and a pre-test–post-test control group experimental design was employed. The students were randomly assigned into two groups: an experimental group and a control group. The experimental group used cooperative Jigsaw II as an instruction method while the control group used traditional teacher-centred instruction. The groups were administered an achievement test, as a pre-, post- and delayed post-test. The results revealed statistically significant differences in favour of the experimental group on the dependent variables of improving vocabulary knowledge and learning active–passive voice in English. The attitude scale results showed that the cooperative learning experience had a significant positive effect on engineering students' attitudes towards learning English and promoted better interactions among students as well. 相似文献

For this study the researchers designed learning activities to enhance students’ high level cognitive processes. Students learned new information in a classroom setting and then applied and analyzed their new knowledge in familiar authentic contexts by taking pictures of objects found there, describing them, and sharing their homework with peers. An experiment was carried out in which 58 junior high school students were divided into a control (n = 30) and an experimental (n = 28) group. The control group studied and completed learning activities with traditional textbooks while the experimental group used electronic textbooks and a learning system, Virtual Pen for Tablet PC (VPenTPC), in order to gauge the feasibility of the proposed approach. The post-test results show a significant difference between the control and experimental groups. In our analysis of the various approaches students took to complete the task, we were able to identify thirty cognitive and metacognitive strategies for using mobile technology, from which we selected the ten most frequently used ones. The results show that low ability students make better use of strategies than their high ability peers, resulting in significant learning gains. The results also show that most students perceive VPenTPC positively. Based on these results, we suggest some implications along with conclusions and directions for future research. 相似文献

A mastery learning strategy was used to teach undergraduate microbiology to part‐time HNC and BSc students. Their performance was cognitively assessed in terms of Bloom's taxonomy. Their changes of attitude were measured by comparison of questionnaires after the introduction to the strategy and after the return of the assessed post‐test. Two performance groups were discovered. Both groups showed positive attitude changes toward the tutor controlling the learning experience and toward the quality of the learning materials. The low group showed negative change toward the strategy and expressed a preference for more traditional teaching, whilst the high group did the reverse. The students’ conception of the academic level of the package and its level of assessment appeared to be canalised by their knowledge of their course status in the academic hierarchy and not by their performance. It was concluded that cognitive assessment more clearly detects students failing to achieve mastery whilst indicating cognitive areas needing remedial tuition and that mastery strategies should be carefully introduced to students to avoid de‐motivating their learning. The difficulty of constructing such strategies and the time taken is compensated for by their ability to teach broader academic groups. 相似文献

Long-term retention effects of two methods of instruction used one year earlier to teach field-dependent (FD) and field-independent (FI) sixth-grade students to control variables and to transfer this ability to novel tasks were investigated. The study also examined whether or not uninstructed seventh-grade students had acquired this ability on their own. Results indicated that Treatment I produced better retention over time for both FD and FI students than did Treatment II. Treatment II was more effective for FI students than for FD students. Significant main effects for treatment and cognitive style were found on each controlling variables task when the abilities of instructed and uninstructed seventh-grade students were compared. Field-dependent students who had received Treatment I significantly outperformed FD students who had received Treatment II and FD students who had received no instruction on how to control variables. Field-dependent students who had received Treatment II performed about as well as their counterparts who had received no instruction. Field-independent students who had received Treatment I significantly outperformed FI students who had received Treatment II on two of three measures and FI students who had received no instruction on all measures. Field-independent student who had received Treatment II significantly outperformed FI students who had received no instruction on two of three measures. 相似文献

AbstractThis study explored utilizing augmented reality (AR) and project-based learning (PBL) strategies to increase students’ understandings of sociological paradigms and the theorists’ motivations behind their development. Using a posttest-only quasi-experimental control group design with experimental intervention, three groups of students’ scores were compared on a post-unit assessment. The PBL-only group, the PBL-AR group, and a control group were also compared over time on the post-unit assessment, a quiz, and the midterm. PBL-AR students’ scores were higher on all three assessments. The project’s design, implementation, and findings are discussed, along with implications for future curricular redesign using novel tools and technologies. 相似文献

This study (1) explores the effectiveness of the contextualized history of science on student learning of nature of science
(NOS) and genetics content knowledge (GCK), especially interrelationships among various genetics concepts, in high school
biology classrooms; (2) provides an exemplar for teachers on how to utilize history of science in genetics instruction; and
(3) suggests a modified concept mapping assessment tool for both NOS and GCK. A quasi-experimental control group research
design was utilized with pretests, posttests, and delayed posttests, combining qualitative data and quantitative data. The
experimental group was taught with historical curricular lessons, while the control group was taught with non-historical curricular
lessons. The results indicated that students in the experimental group developed better understanding in targeted aspects
of NOS immediately after the intervention and retained their learning 2 months after the intervention. Both groups developed
similar genetics knowledge in the posttest, and revealed a slight decay in their understanding in the delayed posttest. 相似文献

A Direct Instruction approach to remedial reading (Corrective Reading Programme) was evaluated in an urban Comprehensive school over two school years. First year remedial readers were randomly allocated to one experimental and two control groups. Groups were matched for sex. A similar procedure was followed in the second study carried out with the following group of first year remedial readers.
In the first three months of the first study all groups were monitored while receiving the school's usual remedial reading programme. They made comparable gains during this baseline period. Covariance analysis indicated that in the first study the experimental group and control group I (a ‘novelty’ programme) made significantly greater gains, in accuracy and comprehension, than control group 2 (the usual remedial reading programme). Findings from the second study confirmed the suggestion that gains for the experimental group in the first study were partly due to ‘novelty’ effects. Both experimental groups developed better strategies for tackling oral reading tasks (as assessed by miscue analysis) than control groups, however. 相似文献
