The aim of this study was to compare the achievement of prospective primary science teachers in a problem-based curriculum
with those in a conventional primary science teacher preparation program with regard to success in learning about gases and
developing positive attitudes towards chemistry. The subjects of the study were 101 first year undergraduate students, who
were in two different classes and who were taught by the same lecturer. One of the classes was randomly selected as the intervention
group in which problem-based learning (PBL) was used, and the other as the control in which conventional teaching methods
were used. The data were obtained through use of the gases diagnostic test (GDT), the chemistry attitude scale (CAS), and
scales specific to students’ evaluation of PBL such as the peer evaluation scale (PES), self evaluation scale (SES), tutor’s
performance evaluation scale (TPES) and students’ evaluation of PBL scale (SEPBLS). Data were analysed using SPSS 10.0 (Statistical
Package for Social Sciences). In order to find out the effect of the intervention (PBL) on students’ learning of gases, independent
sample t-tests and ANCOVA (analysis of co-variance) were used. The results obtained from the study showed that there was a statistically
significant difference between the experimental and control groups in terms of students’ GDT total mean scores and, their
attitude towards chemistry, as well as PBL has a significant effect on the development of students’ skills such as self-directed
learning, cooperative learning and critical thinking. 相似文献

The aim of this study is to compare the effectiveness of conceptual change text instruction (CCT) in the context of energy
in chemical reactions. The subjects of the study were 60, 10th grade students at a high school, who were in two different
classes and taught by the same teacher. One of the classes was randomly selected as the experimental group in which CCT instruction
was applied, and the other as the control group in which traditional teaching method was used. The data were obtained through
the use of Energy Concept Test (ECT), the Attitude Scale towards Chemistry (ASC) and Science Process Skill Test (SPST). In
order to find out the effect of the conceptual change text on students’ learning of energy concept, independent sample t-tests, ANCOVA (analysis of covariance) and ANOVA (analysis of variance) were used. Results revealed that there was a statistically
significant mean difference between the experimental and control group in terms of students’ ECT total mean scores; however,
there was no statistically significant difference between the experimental and control group in terms of students’ attitude
towards chemistry. These findings suggest that conceptual change text instruction enhances the understanding and achievement. 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

This article reports on the influence of learning strategy instruction on student teachers’ physics achievement, attitude
towards physics, and achievement motivation. A pre-test/post-test quasi-experimental design with matching control group was
used in the study. Two groups of student teachers (n = 75) who were enrolled in an introductory physics course participated in the study. In the experimental group, questioning,
summarizing, and graphic organizers were taught. The control group did not receive any presentation on strategy learning.
Data were collected via the pre- and post-administration of the Physics Course Achievement Test, the Scale of Attitudes towards
Physics, and the Achievement Motivation Scale. Univariate and multivariate analyses of variance on the data revealed no significant
differences in the attitude and achievement motivation between the strategy and control groups. However, the strategy group
students were observed to have a tendency of more positive attitude and motivation than the control group students. Results
also showed that explicit learning strategy instruction was more effective than traditional instruction in improving physics
achievement of the participating students. The implications of these results for physics education are discussed. 相似文献

This study was designed to compare the effects of Team Assisted Individualization (TAI) and Student Teams-Achievement Divisions
(STAD) on fourth grade students’ academic achievement in and attitudes towards mathematics. Seven classes of a school were
randomly selected for this experimental study. Two of these were given instruction through TAI; two through STAD, and the
remaining three were treated as a control group. For the purpose of the data analysis regarding academic achievement, the
3 X 1 covariance analysis was used to compare the groups. As a result of this comparison, both the TAI and STAD methods were
found to have positive effects (d = 1.003 for TAI and d = 0.40 for STAD) on students’ academic achievement in mathematics. The pairwise comparisons showed that the TAI method had
a more significant effect than the STAD method. The scores for the attitude towards mathematics were analyzed by using non-parametric
statistics. As a result of this analysis, no significant difference was observed regarding students’ attitudes towards mathematics. 相似文献

This paper aims to investigate students’ likes and dislikes of the teaching that they have experienced and its effects on
students’ perceptions of the learning environment, student learning and academic performance. The study compares a lecture-based
setting to a student-activating learning/teaching environment, considering both instructional and assessment practices. Data
(N=578) were collected using the Course Experience Questionnaire (Ramsden, 1991) and by means of a standardised test. While
lecture-taught students’ evaluations of the experienced teaching were generally focused and positive, students’ perceptions
of the activating methods varied widely and both extremely positive and negative opinions were present. Also the consequences
of these (dis)likes in instruction for student learning become clear. Moreover, a significant positive linear effect of students’
(dis)likes in instruction on students’ perceptions of the learning environment (except for appropriate assessment), their
learning and their performance was found. This way, the results pinpoint the central role of teaching methods for students’
learning and caution against detrimental consequences of students’ negative appraisal of the teaching methods that they experience.
A matching strategy between a student’s teaching tastes and the teacher’s instructional interventions provides the best educational
prospects. 相似文献

The present study conducted to investigate the contribution of conceptual change texts, accompanied by concept mapping instruction
to eleventh-grade students’ understanding of cellular respiration concepts, and their retention of this understanding. Cellular
respiration concepts test was developed as a result of examination of related literature and interviews with teachers regarding
their observations of students’ difficulties. The test was administrated as pre-test, post-test, and delayed post-test to
a total of 70 eleventh-grade students in two classes of the same high school in an urban area, taught by the same teacher.
The experimental group was a class of 34 students who received conceptual change texts accompanied by concept mapping instruction.
A class of 36 students comprised the control group who received traditional instruction. Besides treatment, previous understanding
and logical thinking ability were other independent variables involved in this study. The results showed that logical thinking,
treatment, previous understanding of cellular respiration concepts each made a statistically significant contribution to the
variation in students’ understanding of cellular respiration concepts. The result also showed that conceptual change texts
accompanied by concept mapping instruction was significantly better than traditional instruction in retention of this understanding. 相似文献

This research study aims to examine the effectiveness of a problem-based learning (PBL) on 9th grade students’ understanding
of intermolecular forces (dipole–dipole forces, London dispersion forces and hydrogen bonding). The student’s alternate conceptions
about intermolecular bonding and their beliefs about PBL were also measured. Seventy-eight 9th grade students were stratified
by cognitive levels and then randomly assigned to experimental (PBL, 40 students) and control (lecture-style teaching, 38
students) groups. Following a preparatory lesson where activation and remediation of existing knowledge occur, a pre-test
was given, and no significant difference was found between the two groups of students (p > .05). After the instruction was completed, a post-test and also a questionnaire related to the quality of the problem,
the teacher’s role and group functioning were administered. Results from the post-test of both groups (p < .05) and questionnaire showed that PBL is affective on students’ achievement, remedying formation of alternate conceptions
and also social skills. 相似文献

The purpose of this study is to demonstrate that dynamic assessment based instruction increases children’s learning by using
a quasi-experimental research design in Korea. In this study, dynamic assessment is defined as a measurement method of the
zone of proximal development (ZPD) as well as the qualitative and quantitative diagnostic information for individual children.
In addition, dynamic assessment based instruction is defined as a teaching method using the diagnostic information types in
order to increase children’s learning. In this study, 59 children between the ages of 4 and 5 participated. Three types of
number concept achievement tests (pre-test, parallel test, and post-test) for each age group were developed and the content
validity, face validity, and split-half reliability were examined. After conducting the pre-test, the children of each age
group were divided into an experimental group and a control group. Dynamic assessment based instruction regarding number concepts
was undertaken only with the experimental group for 4 weeks. Both groups took a post-test after completing the 4 weeks of
classes. The ANCOVA technique wa ls used for data analysis. The result of this study shows that dynamic assessment based instruction
has a significant effect on children’s learning of number concepts (in the case of 4-year-old children, F = 12.34, p<0.01;
5-year-old children, F = 20.03, P<0.01). Therefore, dynamic assessment based instruction should be used widely for children’s
cognitive learning. 相似文献

This study aimed at experimentally investigating the moderating role of instructional conceptions on the effectiveness of
powerful learning environments (PLE) designed in line with the four-component instructional design model (4C/ID-model). The
study also investigated the influence of learning in a 4C/ID PLE on students’ instructional conceptions. To achieve its goal,
a study with a one by one by two pre-test post-test quasi-experimental design was done. Three functionally equivalent classes
of students from three similar (secondary technical) schools were randomly exposed to three different treatments. The participants
consisted of 129 (47, 41, 41) students. The treatments were one control group with a regular method of teaching, and two experimental
groups: a 4C/ID PLE with ICT, and a 4C/ID PLE without ICT. The instructional conceptions questionnaire was administered both
in the pre-and the post-test to assess students’ instructional conceptions. Pre- and post-tests contain retention and transfer
items. Technical teachers were trained to implement the interventions. In contrast to expectation, findings show no moderating
effects of students’ instructional conceptions on the learning environments. Finally, the results indicate that students’
instructional conceptions positively change after implementation of the three interventions. The theoretical, research, and
practical implications of the results for the instructional design and technology community as well as educational practice
are discussed. 相似文献

Empirical studies have shown the positive effects of combining cooperative and mastery learning methods on mathematics achievement higher order questioning skills, and originality, but little is known, at present, about the effects of cooperative-mastery learning in other subject areas or on other cognitive outcomes. The problem of this study was to explore the effects of cooperative and mastery learning methods, alone and in combination, on first and second grade students' learning and retention of basic economic concepts. A 2 X 2 (cooperative X mastery) factorial design compared the achievement of one hundred-twenty students who were individually randomly assigned (using grade level as a stratification variable) to one of four treatment conditions—instruction on basic economic concepts using (1) cooperative learning, (2) mastery learning, (3) cooperative-mastery learning, or (4) a control treatment (no cooperative or mastery learning). All subjects were administered a written pretest, post-test, and delayed post-test on their understanding of economic concepts. To further probe children's understanding of economic concepts, a randomly selected sub-sample of sixty- four students was interviewed using an oral pretest, post-test, and delayed post-test. Overall, the results support the superiority of the cooperative-mastery learning method over either method alone in promoting the acquisition and retention of economic concepts. Pretest data verified the initial equivalence of groups. The cooperative-mastery learning group outperformed (a) the control group on all post-tests and delayed post-tests and (b) the cooperative learning group on all post-tests and delayed post-tests except the written post-test. By delayed post-test on the oral measure, the cooperative-mastery learning group was also outperforming the mastery learning group. As further evidence of the superiority of the cooperative-mastery learning method, the mean score of the cooperative-mastery learning group was greater than the combined mean scores of the mastery and cooperative learning groups on the oral post-test and delayed post-test. The authors suggest that the cooperative-mastery learning method is in line with current early childhood practices and has the capacity for simultaneously boosting the conceptual development and language development of young children. This capacity is said to stem from the method's provision of (a) specific, positive feedback, (b) a social context for sustained effort and involvement in a topic, (c) child-child communication exchanges, and (d) adult-child communication exchanges. 相似文献

The purposes of this study were to investigate students’ conceptual learning outcomes and the effect of motivation on students’
conceptual learning outcomes in two different contexts: a Web-based and a classroom-based instruction, which incorporated
the Dual Situation Learning Model (DSLM). Nine classes of Grade eight students (N = 190) were involved in the study; five classes participated in a Web-based context and four classes in a regular classroom-based
context. The topic covered was chemical reaction. Students’ conceptual change outcomes were assessed using eight two-tier
pre/post conceptual tests during the instruction and the reaction rate integrated conceptual test at the end of the instruction.
Students’ motivation data were collected in the beginning and during instruction using the items from the Students’ Motivation
Toward Science Learning (SMTSL) questionnaire. The data were analyzed using ANOVA, ANCOVA, bivariate correlation, and multiple
regression analysis. Findings revealed that students’ motivational factors were correlated significantly with their conceptual
learning outcomes in both Web-based and classroom-based science teaching. In the Web-based context, students’ motivation during
the Web-based learning played a more important role on students’ conceptual learning outcomes than before learning. 相似文献

The main goal of this study was to integrate gender and group effect into bridging strategy in order to assess the effect
of bridging analogy-based instruction on sophomore students’ misconceptions in Newton’s Third Law. Specifically, the authors
developed and benefited from anchoring analogy diagnostic test to merge the effect of group and gender into the strategy.
Newton’s third law misconception test, attitude scale toward Newton’s third law, and classroom observation checklists were
the other measuring tools utilized throughout this quasi-experimental study. The researchers also developed or used several
teaching/learning materials such as gender and group splitted concept diagrams, lesson plans, gender splitted frequency tables,
make sense scales, PowerPoint slides, flash cards, and demonstrations. The convenience sample of the study chosen from the
accessible population involved 308 students from two public universities. The results of multivariate analysis of covariance
indicated that the bridging strategy had a significant effect on students’ misconceptions in Newton’s third law whereas it
had no significant effect on students’ attitudes toward Newton’s third law. 相似文献

In this study, the author implemented a problem-based learning (PBL) experience that allowed students in an advanced science
methodology course to explore differentiated instruction. Through working systematically in small, collaborative groups, students
explored the nature of differentiated instruction. The objective of the study was to examine pre-service teachers’ developing
conceptions of differentiated instruction (DI) as a way to teach for diversity. The author adopted action research as a strategy
to explore students’ perceptions of DI in the context of science teaching and learning. Several data collection methods and
sources were adopted in the study, including student-generated products, student interviews, classroom observation, and journal
writing. Outcomes report on students’ perceptions of both the potential and challenges associated with adopting a DI approach
to science teaching and learning. 相似文献

The objective of this study was to construct a teaching strategy for facilitating students’ conceptual understanding of the
boiling concept. The study is based on 52 freshman students in the primary science education department. Students’ ideas were
elicited by a test consisting of nine questions. Conceptual change strategy was designed based on students’ alternative conceptions.
Conceptual change in students’ understanding of boiling was evaluated by administering a pre-, post- and delayed post-test.
The test scores were analysed both by qualitative and quantitative methods. Statistical analysis using one-way ANOVA of student
test scores pointed to statistically significant differences in the tests and total scores (p < 0.05). Quantitative analysis of students’ responses on each test revealed different schema about changing their knowledge
system. Both qualitative and quantitative analyses suggest that the teaching activities facilitated students’ conceptual understanding.
No statistically significant differences were found between post-test and delayed post-test scores, suggesting that the teaching
strategy enabled students to retain their new conceptions in the long-term memory. 相似文献

The aim of this study was to investigate the effectiveness of instruction supplemented by conceptual change texts (CCTs) over
traditional instruction on students’ understanding of electrochemical (galvanic and electrolytic) cell concepts. The participants
of the study consisted of 64 students from the two classes of a high school located in Turkey. Classes were randomly assigned
to experimental group, which was exposed to CCTs as a supplementary material, and to control group, which was exposed to traditional
instruction. A 23-item multiple-choice test was developed assess students’ conceptual understanding of electrochemical cells.
This test was administered to both groups before and after the instruction. The results of ANCOVA indicated that students
who were instructed by using CCTs had better conceptual understanding of electrochemical cells than those experiencing traditional
instruction when their prior electrochemical cell concepts understanding was statistically controlled. The findings of this
study suggest that CCTs can be used as a cost- and resource-effective supplement to classroom instruction to promote students’
understanding science concepts. 相似文献

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 purpose of the study was to investigate the effectiveness of case-based learning instruction over traditionally designed
chemistry instruction on eleventh grade students’ epistemological beliefs and their attitudes toward chemistry as a school
subject. The subjects of this study consisted of 63 eleventh grade students from two intact classes of an urban high school
instructed with same teacher. Each teaching method was randomly assigned to one class. The experimental group received case-based
learning and the control group received traditional instruction. At the experimental group, life cases were presented with
small group format; at the control group, lecturing and discussion was carried out. The results showed that there was a significant
difference between the experimental and control group with respect to their epistemological beliefs and attitudes toward chemistry
as a school subject in favor of case-based learning method group. Thus, case base learning is helpful for development of students’
epistemological beliefs and attitudes toward chemistry. 相似文献

INVESTIGATING THE EFFECTIVENESS OF AN ANALOGY ACTIVITY IN IMPROVING STUDENTS’ CONCEPTUAL CHANGE FOR SOLUTION CHEMISTRY CONCEPTS 总被引:1,自引:0,他引:1

This paper reports on an investigation on the use of an analogy activity and seeks to provide evidence of whether the activity
enables students to change alternative conceptions towards views more in accord with scientific views for aspects of solution
chemistry. We were also interested in how robust any change was and whether these changes in conceptual thinking became embedded
in the students’ long-term memory. The study has its theoretical basis in an interpretive paradigm, and used multiple methods
to probe the issues in depth. Data collection consisted of two concept test items, one-on-one interviews, and student self-assessment.
The sample consisted of 44 Grade 9 students selected from two intact classes (22 each), from Trabzon, Turkey. The interviews
were conducted with six students selected because of evidence as to their significant conceptual change in solution chemistry.
The research findings revealed statistically significant differences in pre-test and post-test scores, and pre-test and delayed
post-test scores (p<0.05), but no differences between post-test and delayed test scores (p>0.05). This suggests that the analogy activity is helpful in enhancing students’ conceptual understanding of solution chemistry,
and that these changes may be stored in the students’ long-term memory. 相似文献

This study explored the effects of congruency between preferred and actual learning environment (PLE & ALE) perceptions on
students’ science literacy in terms of science concepts, attitudes toward science, and the understanding of the nature of
science in an innovative curriculum of High Scope Project, namely Sci-Tech Mind and Humane Heart (STMHH). A pre-/post-treatment
experiment was conducted with 34 Taiwanese tenth graders involved in this study. Participating students’ preferred learning
environment perception and pre-instruction scientific literacy were evaluated before the STMHH curriculum. Their perceptions
toward the actual STMHH learning environment and post-instruction scientific literacy were also examined after the STMHH.
Students were categorized into two groups; “preferred alignment with actual learning environment” (PAA) and “preferred discordant
with actual learning environment” (PDA), according to their PLEI and ALEI scores. The results of this study revealed that
most of the students in this study preferred learning in a classroom environment where student-centered and teacher-centered
learning environments coexisted. Furthermore, the ANCOVA analysis showed marginally statistically significant difference between
groups in terms of students’ post-test scores on scientific literacy with the students’ pre-test scores as the covariate.
As a pilot study with a small sample size aiming to probe the research direction of this problem, the result of marginally
statistically significant and approaching large sized effect magnitude is likely to implicate that the congruency between
preferred and actual learning environments on students’ scientific literacy is noteworthy. Future study of this nature appears
to merit further replications and investigations. 相似文献
