This study was a mixed quantitative–qualitative research to evaluate the efficacy of a designed student-centred instructional (DSCI) program for teaching about acids and bases. The teaching innovation was designed based on constructivist, hands-on inquiry and context-based approaches and implemented in seven 45-min lessons with a class of 36 grade 11 students (experimental group) from a public senior high school in Indonesia. Another class of 38 students (comparison group) from the same school was instructed using a traditional teacher-centred approach. Data were obtained using a (1) 12-item achievement test on acids and bases that was administered to both groups as a pretest and a posttest, (2) self-evaluation 13-item questionnaire on students’ perceptions of their competence and confidence in carrying out the inquiry activities that was administered to the experimental group and (3) 3-item open-ended questionnaire on students’ perceptions of the instructional process using the DSCI that was administered to the experimental group. The results of the study showed that the teaching innovation was effective in improving students’ understanding of acid–base concepts with significant difference between the two groups on the posttest mean scores. Moreover, the effectiveness of the innovation was supported by an increase in students’ interest in learning science as indicated by their (1) positive perceptions of their engagement and competence in doing inquiry activities, (2) positive perceptions of the learning environment and (3) positive outcome expectations. The findings have implications for chemistry teaching in any institution with similar achieving students as well as for the professional development of teachers.  相似文献

The objective of this paper is to compare the Jigsaw III technique (of cooperative learning) with the instructional teacher-centered teaching method in six graders in terms of the effect of written expression on their academic success. The universe of the study consists of 71 sixth-grade students studying during 2009–2010 academic term in a primary school in the province of Erzurum. Two classes were randomly selected: one (n = 35) of which was the control group where teacher-centered teaching method was applied, the other being experimental group (n = 36) where the Jigsaw III technique was applied. In the study, one of the most common application, pretest/posttest with control group experimental design, was chosen. The data regarding the academic success of the groups were collected by means of the achievement test in Turkish course as pretest, posttest and retention test; the students’ opinions about the group works were obtained through feedback form, group work opinionnaire, and data were analyzed through 11.5 SPSS program. The results of the statistical analysis of teaching a written expression course showed that the experimental group did significantly better than the control group in terms of academic success. In addition, it can be said that the students had positive impressions on the Jigsaw III technique.  相似文献

This article introduces a set of distance education astronomy laboratory exercises for use by college students and instructors and discusses first usage results. This General Astronomy Education Source exercise set contains eight two-week projects designed to guide students through both core content and mathematical applications of general astronomy material. Projects are divided between hands-on activities and computer-aided analyses of modern astronomical data. The suite of online resources includes student and instructor guides, laboratory report templates, learning objectives, video tutorials, plotting tools, and web-based applications that allow students to analyze both images and spectra of astronomical objects. A pilot usage study indicates that distance learners using these materials perform as well as or better than a comparison cohort of on-campus students. The authors are actively seeking collaborators to use these resources in astronomy courses and other educational venues.  相似文献

One of the most intriguing questions for those who study intellectually gifted students is why some of them reach peak performances at school and others don’t. Moderator theories of giftedness assume that domain-specific gifts are transformed into achievement in a process influenced by non-cognitive and environmental variables. Thus, the current study investigates differences in the non-cognitive construct motivation (achievement goals, interest, self-concept, self-efficacy, implicit theories) and perception of classroom environment (classroom structure, class climate) between mathematically gifted high achievers (n = 66) and mathematically gifted students with non-high achievement (n = 144) using a latent variable approach. Gifted high achievers expressed higher levels of motivation than non-high achievers. Furthermore, they perceived a classroom structure that provides more tasks with a focus on learning and more autonomy.  相似文献

ABSTRACT

The purpose of this study was to investigate the effectiveness of the advance organiser model (AOM) on students’ academic achievement in learning work and energy. The design of the study was quasi-experimental pretest–posttest nonequivalent control groups. The total population of the study was 139 students of three sections in Endabaguna preparatory school in Tigray Region, Ethiopia. Two sections with equivalent means on the pretest were taken to participate in the study purposely and one section assigned as the experimental group and the other section assigned as the control group randomly. The experimental group was taught using the lesson plan based on the AOM, and the control group was taught using the lesson plan based on the conventional teaching method. Pretest and posttest were administered before and after the treatment, respectively. Independent sample t-test was used to analyse the data at the probability level of 0.05. The findings of the study showed that the AOM was more effective than the conventional teaching method with effect size of 0.49. This model was also effective to teach male and female students and objectives namely understanding and application. However, both methods were equally important to teach work and energy under the objective knowledge level.  相似文献

Teachers’ attitudes toward science, especially toward astronomy, are considered to be an important aspect of teaching and learning astronomy in school. Research findings to date remain inconclusive as to whether attitudes toward science change with the science courses taken or with increasing achievement. Therefore, preservice teacher attitudes were investigated in two contexts: the first examined how a semester-long moon phase instruction course changed preservice teacher attitudes toward astronomy, and the second considered how preservice teacher attitudes toward astronomy may change over the course of a four-year science teacher training programme. A total of 638 preservice elementary teachers participated in the study. The results indicated that a semester-long training course does not change attitudes, but the four-year programme does significantly change participant attitudes toward astronomy. Astronomy courses should be spread over the four-year programme using modules with few credit hours instead of one course with a large number of credit hours.  相似文献

This study explored the effects of a Problem-Based Computer-Assisted Instruction (PBCAI) on students' earth science achievement in Taiwan. One hundred and fifty-nine 10th grade students enrolled in four sections of a mandatory earth science course participated in this pretest–posttest control-group experiment. During a 2-week period, the experimental group students (n = 84) received the PBCAI while the comparison group students (n = 75) received a Direct-Interactive Teaching Method (DITM) accompanying with regular computer-internet usage. An analysis of covariance on the Earth Science Achievement Test posttest scores with students' IQ and pretest scores as the covariates suggested that (a) the PBCAI was more effective in promoting students' achievement than was the DITM (F = 4.91, p < .028), and that (b) students in the experimental group had significantly higher achievement scores than did students in the comparison group, especially on the knowledge (F = 7.74, p < .017) and comprehension (F = 5.73, p < .017) test items, but not on the application (F = .07, p > .017) test items.  相似文献

The present study compares the highly interactive cloud-classroom (HIC) system with traditional methods of teaching materials science that utilize crystal structure picture or real crystal structure model, in order to examine its learning effectiveness across three dimensions: knowledge, comprehension and application. The aim of this study was to evaluate the (HIC) system, which incorporates augmented reality, virtual reality and cloud-classroom to teach basic materials science courses. The study followed a pretest–posttest quasi-experimental research design. A total of 92 students (aged 19–20 years), in a second-year undergraduate program, participated in this 18-week-long experiment. The students were divided into an experimental group and a control group. The experimental group (36 males and 10 females) was instructed utilizing the HIC system, while the control group (34 males and 12 females) was led through traditional teaching methods. Pretest, posttest, and delayed posttest scores were evaluated by multivariate analysis of covariance. The results indicated that participants in the experimental group who used the HIC system outperformed the control group, in the both posttest and delayed posttest, across three learning dimensions. Based on these results, the HIC system is recommended to be incorporated in formal materials science learning settings.  相似文献

The investigation of leisure time activities through lifespan analysis has revealed the importance of such activities in the prediction of later life achievements and creative products. They may be more reliable predictors of future performance than IQs, creativity test scores or school achievement. In the present paper creative leisure time activities are considered to be creative products. A total of 192 fifteen year old academic secondary school students were involved in the study: Creative leisure time inventories were filled out, Raven Advanced Progressive Matrices administered, and school grades recorded. Results indicated that differences in leisure time inventory scores between boys and girls with high intellectual potential were smaller than those of students with average potential. Girls were overrepresented in the “schoolhouse gifted” group, but in the “creative gifted” and “intellectually gifted” groups the ratio of girls and boys was balanced.  相似文献

This study examined changes in student motivation and achievement in science during a visit to a university children’s science museum. The study was based on the pretest–posttest control comparison group design with four treatment groups: control, exhibit, lesson and exhibit/lesson. The sample consisted of 228 sixth-grade students from a Louisiana public school who were randomly assigned to one of the four experimental groups. Pretest, posttest and delayed posttest measures of intrinsic motivation and achievement in science were obtained using the Children’s Academic Intrinsic Motivation Inventory and an achievement test written to measure areas of science incorporated in the museum exhibits. The data were analysed using a one-way ANOVA, dependent t tests and Pearson r. Significant differences were found within groups for (1) the lesson group in motivation and (2) the exhibit group in achievement from pretest to posttest and from posttest to delayed posttest. A significant relationship between level of motivation and science achievement was revealed for the exhibit group on the delayed posttest. There were no other significant findings to support that the treatment led to any long-term effects on motivation or achievement within any of the four experimental groups.  相似文献

About 9,000 West German students representing the whole range of academic aptitude were examined at the beginning of their 13th school year. A general scholastic aptitude test was administered, and school marks and information on the pupils’ extracurricular interests and activities recorded. A group of highly gifted students was defined in terms of exceptional performance both in school and on the scholastic aptitude test. The extracurricular activities of this group were compared with those of the representative group. The popular hypothesis that superior cognitive giftedness and outstanding achievement in school go with an ‘impoverishment’ of extracurricular activities was not supported: In most areas a larger percentage of the highly gifted than of the reference group were actively involved. Furthermore, the range of individual activities was somewhat broader among the top students than among the representative group.  相似文献

ABSTRACT

A hands-on instructional approach with medium-achieving 10th-grade students (N = 294) successfully demonstrated the achievement of a conceptual change. Two teaching variations were applied (I-1, I-2), both dealing with a hands-on gene technology lesson in an out-of-school laboratory. I-2 additionally confronted the participants with alternative conceptions to some of the central issues involved in gene technology following a constructivist teaching model. The authors monitored the percentage of alternative conceptions by pretest, posttest, and delayed posttest. In the long term, I-2 abandoned more of students’ alternative conceptions in favor of the orthodox scientific view. Furthermore, a gender effect appeared: In the short term, more young men within I-2 were forced to shift to more scientific conceptions. Young women filed their alternative conceptions also in the long term, independently of the applied instructional method.  相似文献

ABSTRACT

The purpose of this study is to investigate the effect of MagAR, an instructional material for teaching magnetism using augmented reality and sensing technology, on students’ academic achievement and learning process, and to identify students’ views about augmented reality. An embedded mixed-method approach was employed in this study. The study’s results suggest that AR learning environments are effective in teaching physics, and facilitate learning by adding visual and textual components to the learning process. In learning activities integrated with AR, the students were observed to participate more, appeared more comfortable, were able to answer questions related to the subject more easily, had increased self-confidence and exhibited higher academic achievement levels in physics. The results suggest that AR should not be considered as an independent learning environment for the teaching of physics, but would be more effective as supplementary to the laboratory environment.  相似文献

The use of questions in the classroom has been employed throughout the recorded history of teaching. One still hears the term “Socratic method” during discussions of questioning procedures. The use of teacher questions is presently viewed as a viable procedure for effective instruction. This study was conducted to investigate the feasibility of training teachers in the use of a questioning technique and the resultant effect upon student learning. The Post-Test Only Control Group Design was used in randomly assigning teachers and students to experimental and control groups. A group of teachers was trained in the use of a specific questioning technique. Follow-up periodic observations were made of questioning technique behavior while teaching science units to groups of students. Post-unit achievement tests were administered to the student groups to obtain evidence of a relationship between the implementation of specific types of teacher questions and student achievement and retention. Analysis of observation data indicated a higher use of managerial and rhetorical questions by the control group than the experimental group. The experimental group employed a greater number of recall and data gathering questions as well as higher order data processing and data verification type questions. The student posttest achievement scores for both units of instruction were greater for the experimental groups than for the control groups. The retention scores for both units were Beater for the experimental groups than for the control groups.  相似文献

This study examined the relationship between learning style awareness and academic achievement of community college students. The study was undertaken to determine if learning style awareness alone, without a change in the manner of teaching or in the matching of student and instructor styles, would benefit community college students as evidenced by an increase in academic achievement. The sample consisted of 78 second term anatomy students at Florida Community College in Jacksonville who were taught by two instructors who used comparable content and methods. By random assignment, half the group served as a control; the treatment half was given a learning style inventory, the Productivity Environmental Preference Survey (PEPS) by Dunn, Dunn, and Price (1979). The PEPS profiles were returned at mid‐term and were interpreted for each student. Individualized study tips for using learning style preferences advantageously were provided. All students were exposed to the same classroom experiences. Summed unadjusted scores of 105 objective items of common first and second classroom tests served as pretest scores. Scores of the 105‐item comprehensive final examination were used as posttest scores. An ANCOVA was performed using the pretest scores as covariates. There was a significant difference in academic achievement in favor of the learning style awareness group (p<.05).  相似文献

Abstract

The issue of school choice and its effects on student performance have become a prevalent part of the educational landscape. This longitudinal investigation examines a group of students not typically associated with the school choice movement: high ability or “gifted” students. The study analyzed whether attending a private school through participation in the Cleveland Scholarship and Tutoring Program, which is among the longest running experimental evaluations of a school voucher program in the United States, resulted in differential performance on standardized achievement tests for topperforming students. Analyses showed that no statistically or practically significant differences were found between gifted students participating in the program and control group students who attended public schools.  相似文献

This two-group quasi-experimental study investigated the effects of the Online Advance Organizer Concept Teaching Material (ONACOM) integrated with inquiry teaching and expository teaching methods. Grade 7 students’ posttest performances on the light unit achievement and light unit attitude tests controlled for gender, previous semester science grade, and pretest scores were analyzed. No significant treatment effects were found between the inquiry and expository approaches. However, both groups demonstrated significant pretest–posttest gains in achievement and attitude. Independent from the method used, ONACOM was judged effective in both groups as students demonstrated increased achievement and attitude scores. ONACOM has a social and semantic network-aided infrastructure that can be adapted to both methods to increase students’ achievement and improve their attitude.  相似文献

Abstract

The study to determine if concepts of school law could be effectively taught, using simulated materials presented audio-tutorially, to preservice teachers. A senior class of 219 students at Iowa State University was randomly divided into two groups. One group was taught school law concepts utilizing the traditional lecture method of instruction, the other was subjected to the A-T style of instruction. A pretest and posttest was administered to each group and the growth of each group over time was determined. The experimental (A-T) group showed a significantly greater (.01 level of confidence) increase in achievement than did the traditional group. Three factors and their interactions were considered in the experiment: achievement level of the student; possible student teaching experience, and group assignment. The only significant factor was group assignment, indicating that teaching technique was responsible for the difference in the learning rate of the two groups.  相似文献

This current, longitudinal study addresses two critical issues related to underrepresented gifted: identification and programming. As a follow‐up of minority and low‐income students identified as gifted in middle school, the study provides insight into the potential predictive value of specific gifted attributes on later academic performance: high‐school graduation, matriculation in an institution of higher learning, and completion of a college degree. Findings support the value of multiple forms of identification, specifically in problem‐solving, teacher identification of leadership ability, and grade point average. The study also evaluates the impact on academic outcomes of a long‐term, university/school pre‐college partnership program for middle‐ and senior‐high‐school underrepresented gifted. Results show a significant relationship between the level of student involvement in program activities and successful achievement of academic outcomes.  相似文献
