Computers and Traditional Teaching Practices: Factors influencing middle level students’ science achievement and attitudes about science

The purpose of this study was to examine the association of middle school student science achievement and attitudes toward science with student-reported frequency of using computers to learn science and other classroom practices. Baseline comparison data were collected on the frequency of student-centred teaching practices (e.g. the use of group experiments during science class) and traditional teaching practices (e.g. having students copy notes during science class) to learn science. The student sample was composed of 294 seventh-grade students enrolled in middle school science. Multiple regression was used to investigate the association of attitudes toward science, student-centred teaching practices, computer usage, and traditional teaching practices with science achievement. Both attitudes toward science and student-centred teaching practices were positively associated with science achievement, and student-centred teaching practice was positively associated with attitude toward science. Computer usage was found to have a negative association with student achievement, which was moderated by traditional teaching practices.     

Effectiveness of Using Computer-Assisted Supplementary Instruction for Teaching the Mole Concept

This study examined the effect of computer-assisted instruction (CAI), used as a problem-solving supplement to classroom instruction, on students' understanding of chemical formulas and mole concept, their attitudes toward chemistry subjects, and CAI. The objective was to assess the effectiveness of CAI over recitation hours when both teaching methods were used as a supplement to the traditional chemistry instruction. We randomly selected two classes in a secondary school. Each teaching strategy was randomly assigned to one class. The experimental group received supplementary instruction delivered via CAI, while the control group received similar instruction through recitation hours. The data were analyzed using two-way analysis of variance and t-test. It was found that the students who used the CAI accompanied with lectures scored significantly higher than those who attended recitation hours, in terms of school subject achievement in chemistry and attitudes toward chemistry subjects. In addition, there was a significant improvement in the attitudes of students in the experimental group toward the use of computers in a chemistry course. There was no significant difference between the performances of females versus males in each treatment group.     

A cluster analysis of high school science classroom environments and attitude toward science

This study provides a test of a theory which suggests that student perceptions of their classroom environment affect their attitudes toward science. Using the statistical technique of cluster analysis, 27 high school science classes were divided into three distinct clusters which were most distinguishable by the amount of involvement, affiliation with students, teacher support, order and organizations, and innovative teaching strategies. One of the clusters provided a classroom environment which was significantly different from the other two and the students in that environment had more positive attitudes toward science. The dimensions of the classroom environment which make a difference are those which teachers may develop and change in order to enhance the science attitudes and, possibly, the science achievement of their students.     

Learning Environment, Attitudes and Achievement among Middle-school Science Students Using Inquiry-based Laboratory Activities

This study compared inquiry and non-inquiry laboratory teaching in terms of students’ perceptions of the classroom learning environment, attitudes toward science, and achievement among middle-school physical science students. Learning environment and attitude scales were found to be valid and related to each other for a sample of 1,434 students in 71 classes. For a subsample of 165 students in 8 classes, inquiry instruction promoted more student cohesiveness than non-inquiry instruction (effect size of one-third of a standard deviation), and inquiry-based laboratory activities were found to be differentially effective for male and female students.     

A study of the perceptual orientation of community college students and their attitudes toward science as they relate to science achievement

The purpose of this study was to investigate the perceptual orientation and attitudes toward science of freshman community college students and the relationship of these characteristics toward science achievement. It was found that perceptual orientation (field independence-dependence) was related to attitudes toward science. In addition, it was found that students who were field independent and possessed a positive attitude toward science scored significantly higher on the science achievement test than students who were field dependent and possessed a negative attitude toward science.     

Influence of resequencing general science content on the science achievement,attitudes toward science,and interest in science of sixth grade students

This study was designed to determine the influence of resequencing general science content on sixth grade students' science achievement, attitudes toward science, and interest in science. Resequencing content was accomplished for experimental group students through revising the order of textbook chapters in a general science course, in order to clarify content structure and establish interrelationships among major concepts. The subjects were 203 sixth grade learners randomly assigned to the two treatment groups of resequenced content and nonresequenced content. The findings revealed that students for whom content structure was clarified through resequencing general science chapters exhibited significantly higher science achievement, significantly more positive attitudes toward science, and significantly greater interest in science than students for whom general science content was not resequenced.     

Investigation of the science achievement models for low and high achieving schools and gender differences in Turkey

A science achievement model was separately investigated for students in low and high achieving schools (LAS and HAS) in Turkey. Then, gender differences based on variables that significantly contributed to each achievement model were investigated. The student-level variables that were under investigation for multiple regression analyses include attitudes toward science, epistemological beliefs, metacognition, views on science teaching, and socioeconomic status (SES). The science achievement scores of students on a nationwide exam were used to measure science achievement. Both for LAS and HAS, two schools were selected. Results were reported for 241 and 320 students in LAS and HAS, respectively. According to the results, self-concept in science, knowledge of cognition, SES, importance of science, gradual learning, and views on lab work significantly contributed to the science achievement model in LAS. On the other hand, self-concept in science, SES, gradual learning, studying, and learning science in school significantly contributed to the science achievement model in HAS. Results also revealed that girls outperformed boys on knowledge of cognition and importance of science in LAS. Moreover, girls scored higher than boys on gradual learning and studying in HAS. According to these findings, implications for science education were discussed.     

Relationships of attitude toward classroom environment with attitude toward and achievement in science among tenth grade biology students

The purpose of the study was to examine the relationship of classroom environment to attitudes toward science and achievement in science among tenth grade biology students. An attitude instrument was administered at three times during the school year to measure student attitudes toward science and the classroom environment. The classroom environment measures examined six areas: emotional climate of the science classroom, science curriculum, physical environment of the science classroom, science teacher, other students in the science classroom, and friends attitudes toward science. Student achievement in science was measured by teacher reported semester grades. The results of the study indicated: (1) student attitudes toward the classroom environment predicted between 56 to 61% of the variance in attitudes toward science, (2) student attitudes toward the classroom environment predicted between 5 to 14% of the variance in achievement in science, (3) student attitudes toward science and attitudes toward the classroom environment predicted between 8 and 18% of the variance in achievement in science.     

Effect of a labratory manual design incorporating visual information-processing aids on student learning and attitudes

The elements of visual information-processing theory were applied to the design of a chemistry laboratory manual. The effectiveness of this approach on content learning, practical skill mastery, and attitudes of university students in a general chemistry course was assessed. Two versions of a laboratory manual were developed: an experimental version that promotes visual information processing by integrating pictures or diagrams with text, and a control version identical to the experimental version in both activities and structure, but without pictures or diagrams. Three assessment instruments were used: an achievement test to assess cognitive outcomes, an attitude survey to assess affective outcomes, and a manipulative skills observation checklist to assess psychomotor outcomes. Results showed that the manual incorporating visual information-processing characteristics helped students gain significantly higher scores on measures of achievement and psychomotor skills, and also stimulated students to develop more favorable attitudes toward the laboratory activities. © 1997 John Wiley & Sons, Inc.

Science achievement, gender differences, and experimental work in classes in Slovenia as evident in TIMSS studies

Since 1999, Slovenia has been in the process of introducing nine years of compulsory education to replace the previous eight-year system of compulsory education. Under the new system, the school entry age is six years rather than the former seven years. This reform of the system necessitated a number of other changes, such as those relating to the curriculum and teaching approaches. The purpose of this study was to compare the “new” Slovenian science curriculum with the “old” to ascertain if different relationships exist between the two in terms of achievement and gender, attitudes toward science, and the amount of experimental work undertaken by students in school. Data from the IEA TIMSS 2003 study were used to analyze these relationships. The analyses employed basic statistics and log-linear modeling of the effects of gender, school system, amount of experimental work in school, and students’ science achievement. Compared to students taught under the old curriculum, students taught under the new curriculum performed slightly better on the overall science test. A large decrease in gender differences in achievement was also apparent. The relationship between experimental work and achievement strengthened. Conducting experiments at every lesson related to lower student achievement, while conducting experiments during half of the science lessons related to higher achievement. These findings have a clear message for teachers and policymakers. A moderate amount of time devoted to student experimental work seems to raise science achievement of students as well as promote more positive attitudes toward learning science.     

Two-year study relating adolescents' self-concept and gender role perceptions to achievement and attitudes toward science

To assess the developmental relationship of perceptions of self-concept and gender role identification with adolescents' attitudes and achievement in science, a two-year longitudinal study was conducted. A battery of instruments assessing 16 dimensions of self-concept/gender role identifications was employed to predict students' achievement and attitudes toward science. Specific behaviors studied included self-concept in school and science and mathematics, attitudes toward appropriate gender roles in science activities and careers, and self-perceptions of masculine and feminine traits. One hundred and fifty-five adolescents, enrolled, respectively, in the seventh and eighth grades, participated in the study. Through Fisher z transformations of correlation coefficients, differences in relationships between these two sets of variables were studied for males and females during the two years. Results indicated that students' self-concepts/gender role perceptions were related to both achievement and attitudes toward science, but more related to attitudes than achievement. These relationships became more pronounced for students as they matured from seventh to eighth graders.     

The development and evaluation of physical science curriculum materials designed to improve student attitudes

Physical science curriculum materials designed to improve the attitudes of below-average students were developed from guidelines which reflected the strengths and weaknesses of these students. The materials were administered to ninth and tenth grade students in three average-low ability physical science classes. Students in these classes had I.Q. scores of less than 100, reading achievement below grade placement, and eighth grade science averages of C or below. A control group of three physical science classes was employed. A form of the Semantic Differential was administered as a pretest and posttest. The student who received the materials demonstrated significant improvement in attitudes toward science class and science laboratory.     

The effects of cooperative learning and learner control on high- and average-ability students

The effects of studying alone or in cooperative learning groups on high- and average-ability students were investigated. Also examined were the effects of completing computer-based instruction using either a learner- or program-control version of a lesson. A total of 175 fourth-grade students were classified as being of high or average ability and randomly assigned to paired or individual treatments stratified by ability. Students completed training to enhance small-group interaction before completing a computer-based tutorial and a posttest. Following cooperative learning, students demonstrated increased achievement and efficiency as well as better attitudes toward both the computer lesson and grouping. Students completed more practice items and examples in program-control treatments than in learner-control treatments. However, the form of lesson control did not affect students' achievement or attitudes.     

A program to improve elementary teacher preparation in science at Rollins College

Conclusion The goals of this project were to design and implement a series of courses that would better prepare elementary school teachers to teach science and would promote positive attitudes toward science and science teaching. The initial offering of the first series of courses met with moderate success. Although the courses fostered an increase in cognitive knowledge, the magnitude of the improvement was not what we had anticipated. There was no significant improvement in the attitudes of the students toward science or science teaching. The science course has been revised and is currently being offered for both preservice and inservice teachers. The revisions include lengthening the class time, so that the material can be covered at a more relaxed pace, and increasing the amount of active team teaching by the instructors to further emphasize the interrelations between chemistry and biology and to eliminate the fragmentation of the course. It is hoped that these changes will also have a positive impact on the students’ attitudes toward the course and thus toward science in general.     

Relationship among laboratory instruction,attitude toward science,and achievement in science knowledge

This study investigated the use of a hands-on laboratory program as a means of improving student attitude toward science and increasing student achievement levels in science knowledge. Using a posttest-only control group design, curriculum referenced objective examinations were used to measure student achievement in science knowledge, and a posttest Q-sort survey was used to measure student attitude toward science. A one-way analysis of variance compared the groups' differences in achievement and attitude toward science. Analysis of covariance was used to determine the effect of the laboratory treatment on the dependent achievement variable with attitude toward science as the covariable. The findings showed that students who had regular laboratory instruction (a) scored significantly higher (p < .01) on the objective examination of achievement in science knowledge than those who had no laboratory experiences; (b) exhibited a moderate, positive correlation (r = .406) between their attitude toward science and their achievement; and (c) scored significantly higher (p < .01) on achievement in science knowledge after these scores were adjusted on the attitude toward science covariable. There were no significant differences in achievement or attitude toward science for the limited English proficiency groups. It was concluded that laboratory instruction influenced, in a positive direction, the students' attitude toward science, and influenced their achievement in science knowledge. It was recommended that science instruction include a regular laboratory experience as a demonstrated viable and effective instructional method for science teachers. This model of science instruction has been shown to be effective with students of diverse backgrounds who live within large urban centers. J Res Sci Teach 34: 343–357, 1997.     

The effects of cooperative learning in a physical science course for elementary/middle level preservice teachers

Although many studies have shown the effectiveness of cooperative learning in a variety of settings in grades K–12, relatively few have focused on higher education. This study compared two physical science laboratory sections in a course for elementary/middle level preservice teachers. One section was taught in the traditional method, and the other was instructed using the Learning Together technique of cooperative learning. Comparisons between the two laboratory sections assessed any differences in student achievement and collaborative skills. In addition, the cooperative learning group completed a questionnaire that assessed their perception of the effectiveness of cooperative learning compared to more traditional methods of instruction, and their attitudes toward the laboratory section. Although no significant differences were observed in achievement, the cooperative learning group exhibited significant gains in collaborative skills. By the end of the course, cooperative learning students indicated a high comfort level for the laboratory.

Embedded Mathematics in Chemistry: A Case Study of Students’ Attitudes and Mastery

There are many factors that shape students’ attitudes toward science, technology, engineering and mathematics. This exploratory study of high school students examined the effect of enriching chemistry with math on chemistry students’ attitudes toward math and careers involving math. To measure student attitudes, a survey was administered before and after the 18-week chemistry class; results from the chemistry class were compared to survey results from students in an elective science class that did not emphasize mathematics. At the end of the 18-week period, only the chemistry students exhibited more positive views toward their abilities in mathematics and careers that involve mathematics, as compared to their views at the outset of the course. To ensure that chemistry mastery was not hindered by the additional emphasis on math, and that mastery on state end-of-course examinations reflected knowledge acquired during the math-intensive chemistry class, a chemistry progress test was administered at the start and end of the term. This exploratory study suggests that emphasizing mathematical approaches in chemistry may positively influence attitudes toward math in general, as well as foster mastery of chemistry content.     

Changes in Preservice Teacher Attitudes Toward Astronomy Within a Semester-Long Astronomy Instruction and Four-Year-Long Teacher Training Programme

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.
