Students' achievement in relation to reasoning ability,prior knowledge and gender

This study investigated students' achievement regarding photosynthesis and respiration in plants in relation to reasoning ability, prior knowledge and gender. A total of 117 eighth‐grade students participated in the study. Test of logical thinking and the two‐tier multiple choice tests were administered to determine students' reasoning ability and achievement, respectively. An analysis of covariance (ANCOVA) was conducted to assess the effect of reasoning ability on students' achievement. The independent variable was the reasoning ability (low, medium, high), the dependent variable was the scores on the two‐tier test. Students' grades in science in previous year were used as a covariate. Analysis revealed a statistically significant mean difference between students at high and low formal levels with respect to achievement. Stepwise multiple regression analysis revealed that reasoning ability, prior knowledge and gender were significant predictors of students' achievement in photosynthesis and respiration in plants, explaining 42% of the variance.     

Cognitive Style,Gender, Attitude toward Computer‐assisted Learning and Academic Achievement

This paper reports an investigation of cognitive style, gender, attitude toward using computer‐assisted learning (CAL) and academic achievement among university students. A Group Embedded Figures Test was used to assess students’ cognitive style and a questionnaire was used for the evaluation of students’ attitude toward CAL. The results revealed that students have positive attitudes toward CAL but they were not prepared to rely entirely on CAL. A 2 x 2 ANOVA was used to investigate the effect of cognitive style and gender on the attitude toward CAL. The results revealed that male students preferred using CAL significantly more than females and field dependent students were more prepared to rely entirely on CAL than field independent students. On the other hand, there was a significant difference between males and females in their achievement scores in favour of the male group. But there was no difference between field dependence and field independence groups in their achievement. The results also revealed no significant relationship between students’ attitudes toward CAL and their achievement in these courses.     

Science Achievement and Students’ Self‐confidence and Interest in Science: A Taiwanese representative sample study

The interrelationship between senior high school students’ science achievement (SA) and their self‐confidence and interest in science (SCIS) was explored with a representative sample of approximately 1,044 11th‐grade students from 30 classes attending four high schools throughout Taiwan. Statistical analyses indicated that a statistically significant correlation existed between students’ SA and their SCIS with a moderate effect size; the correlation is even higher with almost large effect sizes for a subsample of higher‐SCIS and lower‐SCIS students. Results of t‐test analysis also revealed that there were significant mean differences in students’ SA and their knowledge (including physics, chemistry, biology, and earth sciences subscales) and reasoning skill subtests scores between higher‐SCIS and lower‐SCIS students, with generally large effect sizes. Stepwise regression analyses on higher‐SCIS and lower‐SCIS students also suggested that both students’ SCIS subscales significantly explain the variance of their SA, knowledge, and reasoning ability with large effect sizes.     

The relationship among college science student achievement,engaged time,and personal characteristics

The relationships among college student science achievement, engaged time (observed and perceived), and personal characteristics of academic aptitude, reasoning ability, attitude toward science, and locus of control were investigated. Measures of personal characteristics were obtained from the subjects (N= 76) of a private, liberal arts junior college before observations began in the lecture classes for the quarter. Instruments used to measure personal characteristics were Scholastic Aptitude Test, Test of Logical Thinking, Test of Scientific Attitude, and Leven-son's Multidimensional View of Locus of Control. Based on a random selection procedure, student engaged time was observed at least ten times for 11 lectures. Achievement tests were constructed and validated for the biology classes. Data were analyzed by multiple regression procedures. The average achievement scores were positively related to academic aptitude and reasoning ability. Positive relationships were found between observed engaged time and academic aptitude and a negative relationship was found between observed engaged time and reasoning ability. Also a positive relationship was found between perceived engaged time and achievement. Pearson product-moment correlations between achievement and observed engaged time were significant as were the correlations between perceived engaged time and achievement. Measure of engaged time (observed and perceived) were also related to each other. The study's data indicate that students who were observed to be engaged were low in reasoning ability or high in academic aptitude. Those who perceived themselves as being engaged achieved more. College instructors who have knowledge of student academic aptitude and reasoning ability may use this knowledge to improve achievement. Engaged time measures were significantly related to achievement, which indicates an instructor should endeavor to keep the students as engaged as possible to enhance achievement. Students who are engaged or pay attention or perceived they are engaged or paying attention during lecture classes achieve more than students who are observed as nonengaged or perceive themselves as nonengaged.     

What are the relative effects of reasoning ability and prior knowledge on biology achievement in expository and inquiry classes?

What factor(s) influence the likelihood a student will succeed in college biology? Some researchers have found the primary determinant to be the student's prior knowledge of biology, while others have found it to be reasoning ability. Perhaps the ability of these factors to predict achievement depends on the instructional method employed. Expository instruction focuses primarily on facts and concepts. Therefore, perhaps the best predictor of achievement in expository classes is domain-specific prior knowledge. Inquiry instruction focuses more on how science is done, i.e., on scientific processes; therefore, perhaps the best predictor in inquiry classes is reasoning ability. This study was designed to test these hypotheses. Students enrolled in a nonmajors community college biology course were pretested to determine reasoning ability and prior knowledge. The number of previous biology courses was also recorded as an indicator of prior knowledge. After a semester of either expository or inquiry (learning-cycle) instruction, students took a comprehensive final examination. Reasoning ability but not prior knowledge or number of previous biology courses accounted for a significant amount of variance in final examination score in both instructional methods and with semester examination and quiz scores in inquiry classes. This suggests that reasoning ability limits achievement more than prior knowledge among these biology students, whether they are enrolled in expository or inquiry classes. Reasoning ability explained more of the variance in final examination scores for students enrolled in expository classes (18.8%) than in inquiry classes (7.2%). The reason for this is not clear, but significant improvements in reasoning were found in the inquiry but not in the expository classes. These improvements were accompanied by significant differences in achievement in the inquiry classes. Perhaps the reasoning improvement facilitated the better and more equal achievement for students in the inquiry classes, thus reducing the correlation between initial reasoning ability and final achievement. © 1998 John Wiley & Sons, Inc.

Instructional strategy change and the attitude and achievement of seventh- and eighth-grade science students

This sequential methodologic elaboration study investigated differences between the middle school and the junior high instructional strategies and the effects on adolescent attitude toward science in school and science achievement. Subjects of the quantitative phase were 570 seventh- and eighth-grade students in one school in an urban school district in the midwest United States during a transition year from junior high to middle school. Germann's Attitude toward Science in School Assessment and the school district's Benchmark Exams were employed to measure student pre- and posttest attitude and achievement. Variations within grade level, gender, race, general ability, and socioeconomic group were evaluated. Results of split plots revealed no significant differences in science attitude between the experimental middle school group and the junior high control group at this phase. However, there was significant improvement in attitude in both seventh-grade populations, but no change in attitude in either eighth-grade population. No significant differences in attitude were found between males and females, Caucasian students and students of color, or students of different ability or socioeconomic groups. Significant increases in science achievement were revealed in the seventh-grade junior high control group, the eighth-grade middle school, and the eighth-grade junior high, but not in the seventh-grade middle school. No significant differences in achievement were found between males and females. Caucasians scored significantly higher in achievement than students of color. Average and high ability students scored significantly higher pretest to posttest, but low ability students did not. High ability students scored significantly higher than both average and low ability groups. There was significant improvement in science achievement for students in the sufficient socioeconomic status group, but not in the low socioeconomic status group. These results were discussed with the five science teachers, the principal, and a university consultant in the setting, who were the informants of the qualitative elaboration phase of the study. Ethnographic methods uncovered themes explaining differences and similarities within the two instructional strategies. Teachers' feelings and stages of concern were identified. The results are discussed in terms of effectively implementing changes in instructional strategies and assessing science achievement of early adolescents.     

Self‐efficacy,reasoning ability,and achievement in college biology

This study compared the relationships of self‐efficacy and reasoning ability to achievement in introductory college biology. Based on the hypothesis that developing formal and postformal reasoning ability is a primary factor influencing self‐efficacy, a significant positive correlation was predicted between reasoning ability and degree of self‐efficacy to complete biological tasks. Further, reasoning ability was predicted to be more highly correlated with course achievement than self‐efficacy. The study involved pre‐ and posttesting 459 introductory biology students. Both self‐efficacy and reasoning ability increased during the semester. As predicted, self‐efficacy and reasoning ability were positively correlated. Depending on the nature of the achievement measure, reasoning ability accounted for some 15 to 30 times more variance in achievement than self‐efficacy. Also, as predicted, reasoning ability was a strong predictor of self‐efficacy, but self‐efficacy was not a strong predictor of reasoning ability. Self‐efficacy estimates and achievement were higher for the concrete tasks than for the formal tasks and higher for the formal tasks than for the postformal tasks. In general, students tended to overestimate their abilities to carry out the concrete, formal, and postformal tasks. Results support the study's working hypothesis that intellectual development continues for some students during the college years, that a postformal level of intellectual development exists, and that reasoning ability is a primary factor influencing both self‐efficacy and achievement. Student overestimation of their abilities may contribute to complacency, lack of effort, and to less than optimal achievement. Consequently, it may be advantageous early in the semester to provide students with particularly challenging tasks that “shock” them out of their complacency and perhaps increase their effort, their reasoning skills, and their achievement. © 2006 Wiley Periodicals, Inc.

The structural relationship between writing attitude and writing achievement in first and third grade students

This study tested three models of the structural relationship between the writing achievement of primary grade students and their attitude towards writing (defined here as an affective disposition involving how the act of writing makes the author feel, ranging from happy to unhappy). The three models tested were: (a) writing attitude influences writing achievement in a unidirectional manner, (b) writing achievement influences writing attitude in a unidirectional manner, and (c) the effects of writing attitude and achievement are bidirectional and reciprocal. The model that best fit the data was based on the assumption that writing attitude influences writing achievement. In addition, the direct path between attitude and achievement in this model was statistically significant. Although third grade students were better writers than first grade students, there was no statistical difference in younger and older students’ attitude towards writing. In addition, girls were more positive about writing than boys, but there was no statistical difference in their writing achievement related to gender. This research extends models based on the cognitive and language processes of writing to include the role of attitude, which is an affective component of motivation.     

Teaching Ecosystems and Matter Cycles with Creative Drama Activities

The purpose of this study is to examine the effect of creative drama-based instruction on seventh graders’ science achievements in the ecology and matter cycles unit and their attitudes toward science. The study is an experimental study carried out in one of the public elementary schools in Turkey during 2005–2006 schooling year. An ecological concept achievement test was developed and administered to 45 students in two classes (as control and experimental group) of an elementary school before and after the treatment. The experimental group received creative drama-based instruction and the control group received traditional instruction. A guiding instruction material which contains six lesson plans in the subject was constructed for the teacher to administer creative drama-based instruction. The topics of ecosystems and matter cycles were taught to the both of groups for 3 weeks. A science attitude test was administered to both groups before and after the treatment. The results revealed a statistically significant difference between the mean scores of the both groups with respect to achievement in the ecology concepts and median of the attitudes toward science in favour of the experimental group after the treatment.     

Student achievement and attitude in a satellite‐delivered high school science course

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.     

Effects of Toy Crane Design-Based Learning on Simple Machines

The aim of this 2-group study was to investigate the following question: Are there significant differences between scaffolded design-based learning controlled using 7 forms and teacher-directed instruction methods for the toy crane project on grade 7 students’ posttest scores on the simple machines achievement test, attitude toward simple machines, and attitude toward creativity in simple machines after adjusting for their respective pretest scores and the prior semester science grades? The study group (N = 65) consisted of grade 7 students in public middle schools in Burdur, Turkey. There were significant treatment effects favoring the first method with large effect sizes on both achievement and creative attitude scores. Teaching topics about simple machines with the design-based method increased students’ achievement and creative attitude without disadvantaging their attitude toward the topic as they constructed new knowledge through each step of the precise process.     

Gender differences in student attitudes toward science: A meta-analysis of the literature from 1970 to 1991

A meta-analysis covering the literature between 1970 and 1991 was conducted using an approach similar to that suggested by Glass, McGaw, and Smith (1981) and Hedges, Shymansky, and Woodworth (1989). This analysis examined gender differences in student attitudes toward science, and correlations between attitudes toward science and achievement in science. Thirty-one effect sizes and seven correlations representing the testing of 6,753 subjects were found in 18 studies. The mean of the unweighted effect sizes was .20 (SD = .50) and the mean of the weighted effect size was .16 (SD = .50), indicating that boys have more positive attitudes toward science than girls. The mean correlation between attitude and achievement was .50 for boys and .55 for girls, suggesting that the correlations are comparable. Results of the analysis of gender differences in attitude as a function of science type indicate that boys show a more positive attitude toward science than girls in all types of science. The correlation between attitude and achievement for boys and girls as a function of science type indicates that for biology and physics the correlation is positive for both, but stronger for girls than for boys. Gender differences and correlations between attitude and achievement by gender as a function of publication date show no pattern. The results for the analysis of gender differences as a function of the selectivity of the sample indicate that general level students reflect a greater positive attitude for boys, whereas the high-performance students indicate a greater positive attitude for girls. The correlation between attitude and achievement as a function of selectivity indicates that in all cases a positive attitude results in higher achievement. This is particularly true for low-performance girls. The implications of these finding are discussed and further research suggested.     

Effects of collaborative group composition and inquiry instruction on reasoning gains and achievement in undergraduate biology

This study compared the effectiveness of collaborative group composition and instructional method on reasoning gains and achievement in college biology. Based on initial student reasoning ability (i.e., low, medium, or high), students were assigned to either homogeneous or heterogeneous collaborative groups within either inquiry or didactic instruction. Achievement and reasoning gains were assessed at the end of the semester. Inquiry instruction, as a whole, led to significantly greater gains in reasoning ability and achievement. Inquiry instruction also led to greater confidence and more positive attitudes toward collaboration. Low-reasoning students made significantly greater reasoning gains within inquiry instruction when grouped with other low reasoners than when grouped with either medium or high reasoners. Results are consistent with equilibration theory, supporting the idea that students benefit from the opportunity for self-regulation without the guidance or direction of a more capable peer.     

How is formative assessment related to students’ reading achievement? Findings from PISA 2009

Drawing on the programme for international student assessment 2009 US data-set, this study examines the relationship between formative assessment and students’ reading achievement using a structural equation modelling approach. We find that formative assessment is positively related to students’ reading achievement directly and indirectly (through teacher–student relationship and attitude towards reading) for all students. The direct relationship between formative assessment and reading achievement is significantly stronger for Black students than for White students, whether or not student socio-economic status (SES), gender and school mean SES are controlled for. The total relationship (the direct plus the indirect relationship) between formative assessment and reading achievement also appears to be stronger for Black students than for White students; however, the difference is not statistically significant whether or not we control for covariates. No significant difference is found between White and Hispanic students in terms of the direct and the total relationship between formative assessment and reading achievement. Using a nationally representative data-set, this study provides empirical evidence that formative assessment is positively related to students’ reading achievement in general. In addition, this study provides preliminary evidence to show the potential of formative assessment to help reduce achievement gaps between Black and White students. The implications and limitations of the study are also discussed.     

Effects of 3D virtual reality of plate tectonics on fifth grade students' achievement and attitude toward science

This study examines the effects of a teaching method using 3D virtual reality simulations on achievement and attitude toward science. An experiment was conducted with fifth-grade students (N = 41) to examine the effects of 3D simulations, designed to support inquiry-based science curriculum. An ANOVA analysis revealed that the 3D group scored significantly higher on the achievement test (F = 7.03, p < .05) than the control group using traditional 2D visuals. A positive change of attitude toward science was identified in both 3D and 2D groups, but it was not statistically significant. A robust regression analysis revealed that neither gender nor ethnicity had any significant effect on achievement tests or attitude. However, prior attitude had a significant determining effect for later attitude in both groups.     

Relationships between attitude and achievement among college biology students

The purposes of this study were to (1) study changes in attitude toward science, school, and academic self among college biology students, and (2) to examine relationships between attitudes and achievement in an introductory college course in biology. The three attitude variables were assessed at the beginning and end of the study. Each of the three constructs was measured by the semantic differential and one additional instrument. One cognitive measure, biology achievement, was taken at the beginning and end of the study. This was accomplished by using the Nelson Biology Test. Another cognitive measure, grade in the course, as given by the instructor, was recorded at the end of the course. Normative data and correlation coefficients among pre- and postadministrations were calculated for each institution and the composite sample as well. An analysis of variance showed that while gains in scores on the Nelson Biology Test were significant beyond the 0.01 level of probability, changes in attitude scores were not. Correlations were calculated between the attitude and cognitive variables in this study. Relationships between academic self-concept and achievement in biology were the strongest. Data from this study show that while student cognitive behavior was changed during an introductory college biology course, selected attitudes either stayed the same or became slightly more negative. Affective as well as cognitive gains would appear to be desirable goals in college courses. As we learn more about relationships that exist between cognition and affect, science educators at all levels will become better equipped to improve learning in science.     

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.     

Correlations among Six Learner Variables and the Performance of a Sample of Jamaican Eleventh-Graders on an Achievement Test on Respiration

This study aimed at establishing if the level of performance of 500 Jamaican Grade 11 students on an achievement test on the concept of respiration was satisfactory (mean=28 or 70% and above) or not (<70%); if there were statistically significant differences in their performance on the concept linked to their gender, cognitive abilities in biology, self-esteem, school location, socioeconomic background (SEB), school-type and school location; and if there were significant relationships among the six variables and the students’ performance. The sample (n=500) consisted of 212 boys and 288 girls selected from five all-boys’ schools (119 students), five all-girls’ schools (159 students), and six coeducational schools (222 students). The students were from six rural schools (137 students) and ten urban schools (363 students), out of which 291 were from a high SEB and 209 were from a low SEB. A 40-item multiple choice test on respiration and a self-esteem questionnaire were used to collect data. The results revealed that the students’ level of performance (mean=23.44 or 58.60%, SD=6.86) was regarded as fairly satisfactory; there were statistically significant differences in the students’ performance on respiration based on their cognitive abilities, and school-type in favour of students with high cognitive ability in biology and all-boys’ schools respectively. There was a positive statistically significant but weak relationship between the students’ (a) cognitive abilities, and (b) school-type and their performance on respiration.     

Testing a model of science process skills acquisition: An interaction with parents' education,preferred language,gender, science attitude,cognitive development,academic ability,and biology knowledge

Path analysis techniques were used to test a hypothesized structural model of direct and indirect causal effects of student variables on science process skills. The model was tested twice using data collected at the beginning and end of the school year from 67 9th- and 10th-grade biology students who lived in a rural Franco-American community in New England. Each student variable was found to have significant effects, accounting for approximately 80% of the variance in science process skills achievement. Academic ability, biology knowledge, and language preference had significant direct effects. There were significant mediated effects by cognitive development, parents' education, and attitude toward science in school. The variables of cognitive development and academic ability had the greatest total effects on science process skills. Implications for practitioners and researchers are discussed.
