Abstract

This study investigated the effect of satellite‐delivered instruction on student achievement and attitude in a high school anatomy and physiology course. The experimental group included students from seven high schools enrolled in the satellite‐delivered course. The control group consisted of students from seven high schools in which classroom teachers provided instruction. An experimental versus control matched‐pair design was used in the study. Two hypotheses were tested using the t test for dependent samples. The findings show that there was no significant difference between the experimental group and control group in attitude toward anatomy and physiology. However, on the achievement test, the mean post‐test score of the experimental group was significantly higher than that of the control group.  相似文献

Abstract

Fifth-grade students (N = 103) from 4 classrooms were administered a multiple-choice test of Piaget tasks (B. J. Wadsworth, 1996). Fifty of the students were identified as preoperational in their cognitive understanding. Two of the classrooms served as the experimental group for 24 identified students; 26 students were in 2 classrooms that served as the control group. The experimental group received special lessons and activities designed to increase abilities in concrete and abstract thinking. The school had a large Hispanic population; therefore, the students received the instruction in the language in which they demonstrated mastery. Students in the experimental group showed a significantly greater increase in concrete operations than did the control group. All the students in the 2 experimental classrooms indicated greater use of concrete operations than did the students in the 2 control classrooms.  相似文献

The study compared the effects of dynamic geometry software and physical manipulatives on the spatial visualisation skills of first‐year pre‐service mathematics teachers. A pre‐ and post‐test quasi‐experimental design was used. The Purdue Spatial Visualisation Test (PSVT) was used for the pre‐ and post‐test. There were three treatment groups. The first group (n = 34) used Dynamic Geometry Software (DGS) Cabri 3D as a virtual manipulative and the second group (n = 32) used physical manipulatives. In the control group (n = 30), the students received traditional instruction. The results of the study showed that physical manipulatives and DGS‐based types of instruction are more effective in developing the students' spatial visualisation skills than traditional instruction. In addition, students in the DGS‐based group performed better than the physical manipulative‐based group in the views section of the PSVT.  相似文献

Forty high school students participated in a study to investigate learning and remembering from physics instruction. At pretest, students received aptitude tests, an alternate form of achievement test (counterbalanced) and a word association (WA) test. Then the 40 students were divided into instruction (N = 28) and control (N = 12) groups. The control group received all subsequent tests but no instruction. The instruction group received physics instruction over five 2-hour sessions. At the end of each session, the WA test was administered; the alternate form of the achievement test was administered at the end of the last session. The instruction and control groups did not differ significantly in achievement at pretest. The instruction group showed a significant gain from pre- to posttest; no such gain was found for the control group. The instruction and control groups did not differ on the number of responses generated on the WA test at pretesting. The number of responses given by students in the instruction group increased significantly from test 1 (pretest) to test 6 (posttest). For the control group, the number of responses increased initially and then leveled out well below the instruction group data. When WA test responses were tallied for “constrained” responses (i.e., tallying only those concepts found in equations defining the stimulus word), the number of constrained responses increased consistently for the instruction group. For the control group, constrained responses showed an initial increase and then leveled out well below instruction group data. Finally, the aptitude, achievement, and WA data were intercorrelated. This analysis suggests that for students who perform well in solving problems at the end of instruction, the physics concepts became meaningful soon after they were introduced. Subsequently, these students were able to consolidate, in memory, the meaning of the concepts and the interrelations among these concepts in the form of equations. Students not able to solve problems at the end of instruction seemed to be completing the process of acquiring the meaning of the concepts.  相似文献

This study investigated the possibility of enhancing the level of preschoolers’ number sense by introducing two intervention programmes, Let’s think! and Young children with special educational needs count, too! .Forty‐five preschoolers, mean age 66.4 months, were randomly assigned to the experimental and control groups. The experimental group received instruction twice a week, for half an hour, and for a period of nine months. Pretest–postest comparison revealed that the experimental group showed enhanced number‐sense performance immediately after the instruction ended, but the between‐group difference faded after six months. There were no statistically significant differences between the groups in general mathematical thinking abilities (transfer tasks) after the intervention.  相似文献

ABSTRACT

The authors investigated the effects of a 5-week note-taking skills instructional program on note-taking and reading comprehension performance of elementary students. The participants included 349 fourth-grade students from 2 elementary schools in Taiwan. The Note-Taking Instruction group received approximately 40 min of note-taking skills instruction per week for 5 weeks in contrast to the free note-taking group and the free-recall writing group who did not receive any instruction. A note-taking evaluation task and a comprehension test were used to evaluate the effectiveness of the instruction on students’ performance in note taking and reading comprehension, respectively. The study yielded 2 findings: first, teaching students a note-taking strategy significantly improved their performance in note taking and reading comprehension, and second, poor readers showed the greatest gains in note-taking skills with instruction.  相似文献

Abstract

?Multitiered systems of reading instruction and intervention, including response to intervention, are widely used in early reading by schools to provide more intense services to students who need them. Research using randomized controlled trials has compared innovative Tier 2 interventions to business-as-usual Tier 2 approaches and established a number of important components that compose effective Tier 2 interventions in early reading. The purpose of this study was to test the impact of a Tier 2 intervention with Tier 2 compared to Tier 1 instruction alone using regression discontinuity. A cut score was used to assign first-grade students at risk for reading difficulties to Tier 2 intervention plus Tier 1 instruction. Students who missed the cut score in the control group received Tier 1 instruction only. Students in the treatment group, just below the cut score, made greater gains on the SAT10 total score and the individual subtests than students just above the cut score. Outcomes were not significant on oral reading fluency.  相似文献

Cooperative learning is an active learning approach in which students work together in small groups to complete an assigned task. Students commonly find the subject of ‘physical and chemical changes’ difficult and abstract, and thus they generally have many misconceptions about it.

Purpose

This study aimed to investigate the effects of jigsaw cooperative learning activities developed by the researchers on sixth grade students’ understanding of physical and chemical changes.

Sample

Participants in the study were 61 sixth grade students in a public elementary school in Izmir, Turkey.

Design and methods

A pre-test and post-test experimental design with a control group was used, and students were randomly assigned to the experimental and control groups. Instruction of the subject was conducted via jigsaw cooperative learning in the experimental group and via teacher-centered instruction in the control group. During the jigsaw process, experimental group students studied the subjects of changes of state, changes in shape and molecular solubility from physical changes, and acid–base reactions, combustion reactions and changes depending on heating from chemical changes in their jigsaw groups.

Results

The concept test results showed that jigsaw cooperative learning instruction yielded significantly better acquisition of scientific concepts related to physical and chemical changes, compared to traditional learning. Students in the experimental group had a lower proportion of misconceptions than those in the control group, and some misconceptions in the control group were identified for the first time in this study.

Conclusions

Jigsaw cooperative learning is an effective teaching technique for challenging sixth grade students’ misconceptions in the context of physical and chemical changes, and enhancing their motivation, learning achievements, self-confidence and willingness in the science and technology lesson. This technique could be applied to other chemistry subjects and other grade levels.  相似文献

ABSTRACT

The effects of cooperative group learning on students’ persistence, self‐regulation, and efforts to please teachers and parents were examined. Eighty‐one high school geometry students were randomly assigned to either a cooperative learning or traditional lecture group. Twenty‐seven students received cooperative group instruction for nine weeks and then received traditional classroom instruction for nine weeks. Twenty‐five students received traditional instruction for nine weeks and then received cooperative group instruction for nine weeks. Twenty nine students received traditional classroom instruction for 18 weeks. Participants completed pre, post, and post‐posttest motivation questionnaires at each phase of the project. Students in the cooperative group classrooms exhibited significantly greater gains in persistence, self‐regulation, and efforts to please their parents and teacher. The implications of these findings for motivation theory and cooperative group structures are discussed.  相似文献

Abstract

The relative effectiveness of a problem-solving-based computer-assisted instruction (PSCAI) and a lecture-Internet-discussion instruction (LIDI) were compared for Taiwan senior high school students' science achievement and attitudes toward science. A pretest-posttest control group experimental design involving 8 classes was used. Experimental-group students (n = 156) received the PSCAI; comparison-group students (n = 138) received the LIDI. Instruments included the Earth Science Achievement Test (C. Y. Chang, 2000) and the Attitudes Toward Earth Science Inventory (C. Y. Chang & S. L. Mao, 1999). A multivariate analysis of covariance suggested that (a) students taught using the PSCAI scored higher but not significantly higher than did students in the LIDI group and (b) there were statistically significant differences in favor of the PSCAI on student attitudes toward the subject matter.  相似文献

Limited research is available on the effectiveness of remedial college courses. The present study evaluated the effectiveness of two instructional approaches for developmental reading courses at a community college in the southwestern United States. The instructional approaches were traditional textbook-based instruction and strategic-reading instruction. The sample consisted of 64 participants. Half (n = 32) of the participants were in the control group (n = 32) and received traditional textbook-based instruction; the other half (n = 32) were in the experimental group and received strategic-reading instruction. All participants completed the Nelson-Denny Reading Form G at the beginning of the semester and then again 12 weeks later, at the end of the semester. The data were then statistically analyzed to identify any relationships between the type of instruction and the differences between the students’ pretest and posttest scores. The null hypotheses for H1 and H2 were rejected because the results of the paired t tests indicated that both traditional textbook-based instruction and strategic-reading instruction have a statistically significant positive effect on students’ performance on the test. A one-way ANOVA was conducted to determine whether the pretest/posttest difference scores varied based on the type of instruction. The findings showed that both methods of instruction were equally effective in improving the reading comprehension skills of community college students in a developmental reading course. Based on the findings, community college leaders are encouraged to assess the effectiveness of the instructional methods used in developmental courses to ensure at-risk community college students are receiving the most beneficial instruction.  相似文献

This study examines the impact of Disaggregate Instruction on students’ science learning. Disaggregate Instruction is the idea that science teaching and learning can be separated into conceptual and discursive components. Using randomly assigned experimental and control groups, 49 fifth‐grade students received web‐based science lessons on photosynthesis using our experimental approach. We supplemented quantitative statistical comparisons of students’ performance on pre‐ and post‐test questions (multiple choice and short answer) with a qualitative analysis of students’ post‐test interviews. The results revealed that students in the experimental group outscored their control group counterparts across all measures. In addition, students taught using the experimental method demonstrated an improved ability to write using scientific language as well as an improved ability to provide oral explanations using scientific language. This study has important implications for how science educators can prepare teachers to teach diverse student populations.  相似文献

In this study, the effect of conceptual-change-texts-oriented instruction to seventh-grade students' understanding of ecological concepts was investigated. Using information collected through interviews and related literature, the Ecology Concept Test was developed and administered to 58 elementary students in two classes of an elementary school before and after the treatment. The experimental group received conceptual-change-texts-oriented instruction and the control group received traditional instruction. Results of independent t test analysis revealed a statistically significant difference between the gain score means of the students in both groups with respect to ecological concepts in favor of experimental group after the treatment.  相似文献

Abstract

An instructional program was developed to teach elementary pupils how to parapluase dictionary defmitions into meaningful sentences. Theoretically, the learner processes the meaning of the new words, thereby improving comprehension. Children who were given the instructional program scored higher on a test of word meaning and received better rating of the sentences they composed, following a series of t1uee study-test trials, than control subjects. A second experimental group that practiced composing parapluased sentences, but who received no special training in how to do so, did not score significantly higher than control subjects, nor significantly lower than members of the instruction group.  相似文献

The present study examined the comparative effects of a prediction/discussion‐based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi‐experimental research design of the pre‐test–post‐test non‐equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion‐based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). Participants completed the genetics concept test as pre‐test, post‐test, and delayed post‐test to examine the effects of instructional strategies on their genetics understanding and retention. While the dependent variable of this study was students' understanding of genetics, the independent variables were time (Time 1, Time 2, and Time 3) and mode of instruction. The mixed between‐within subjects analysis of variance revealed that students in both prediction/discussion‐based learning cycle and CCT groups understood the genetics concepts and retained their knowledge significantly better than students in the traditional instruction group.  相似文献

Abstract

The authors examined the effects of implementing an instructional system that automates application of evidence-based components of effective instruction on student mathematics achievement and on classroom behaviors known to be related to overall student achievement outcomes. A treatment group of 157 4th- and 5th-grade students used the intervention in conjunction with the Everyday Math curriculum. Student performance was compared with a within-school control group of 61 4th- und 5th-grade students, as well as all 4th- and 5th-grade students in the district (N = 6,385). The students in the control groups received only the Everyday Math curriculum. Results indicate that the implementation of the instructional management system as an enhancement to Everyday Math resulted in an increase in the amount of time spent on classroom activities that researchers have identified as contributing to positive academic outcomes. Furthermore, students who used the Accelerated Math program demonstrated greater mathematics achievement gains than did the control groups.  相似文献

Abstract

This study evaluated the effectiveness of interactive television in teaching an MSW foundation research methods course. Specifically, the performance of distant students who received instruction via interactive television was compared with the performance of their peers who received simultaneous face-to-face instruction in an interactive television classroom on-campus and with students who took the course in a traditional classroom. This retrospective analysis of student performance, spanning a four-year period, found that students performed comparably regardless of the setting for the course. The three groups of students studied did not differ statistically on their combined midterm/final examination test scores, the required course paper, or final course grades.  相似文献

Abstract

A comparison was made of hypermedia learning environments and traditional instruction in terms of contribution to declarative, procedural, and conditional knowledge acquisition and retention in a specific subject area through a pretest-posttest control-group design. Thirty-nine 9th-grade biology students were assigned to experimental (hypermedia learning environment) and control (traditional instruction) groups through a matched-pair technique. Both groups were given pre-, post-, and retention tests. Posttest results indicated no significant difference between control and experimental groups in acquisition of declarative, conditional, and procedural knowledge. However, retention test results showed that the experimental group retained all three types of knowledge significantly better than did the control group.  相似文献

In this study we examined the benefits of computer programs designed to supplement regular reading instruction in an urban public school system. The programs provide systematic exercises for mastering word‐attack strategies. Our findings indicate that first graders who participated in the programs made significant reading gains over the school year. Their post‐test scores were slightly (but not significantly) greater than the post‐test scores of control children who received regular reading instruction without the programs. When analyses were restricted to low‐performing children eligible for Title I services, significantly higher post‐test scores were obtained by the treatment group compared to the control group. At post‐test Title I children in the treatment group performed at levels similar to non‐Title I students.  相似文献

Abstract

Twenty-four high school juniors and an equal number of middle school students were randomly assigned to either training or control groups in two settings. Students who were trained received instruction over three days on the use of text lookbacks to answer questions. After one week, trained and control subjects were tested for use of lookbacks and for question-answering accuracy. Only the younger trained students’ performance was significantly superior to that of control-group peers. Possible explanations for differential efficacy of training are discussed.  相似文献
