This study investigated the effectiveness of combining conceptual change text and discussion web strategies on students' understanding
of photosynthesis and respiration in plants. Students' conceptual understanding of photosynthesis and respiration in plants
was measured using the two-tier diagnostic test developed by Haslam and Treagust (1987, Journal of Biological Education 21: 203--211). The test was administered as pretest and posttest to a total of 233 eighth-grade students in six intact classes
of the same school located in an urban area. The test of logical thinking was used to determine the reasoning ability of students.
The experimental group was a class of 116 students received discussion web and conceptual change text instruction. A class
of 117 students comprised the control group received a traditional instruction. After instruction, data were analyzed with
two-way analysis of covariance (ANCOVA) using the Test of Logical Thinking and pretest scores as covariate. The conceptual
change instruction, which explicitly dealt with students' misconceptions, produced significantly greater achievement in understanding
of photosynthesis and respiration in plant concepts. Analysis also revealed a significant difference between performance of
females and that of males in the favor of females, but the interaction of treatment with gender difference was not significant
for learning the concepts. 相似文献

Abstract Ability grouping is supposedly undesirable because it leads to deficits in academic self-concept and academic achievement. However, it appears to be justifiable for its improvement of teaching and learning in schools, perhaps more so in a collectivist culture. In view of the paucity of data examining the controversy in Hong Kong, the authors collected data from 2,720 junior high school students with a random sampling procedure and obtained teachers' reports about the students' subsequent academic achievement, ability grouping, and the ability level of the class. The authors maintained students' past academic achievement as a control variable in predicting their subsequent academic achievement and self-concepts. Results revealed no significant detrimental effect caused by the ability-grouped class and the ability level of the ability-grouped class. Rather, students in classes that were more homogeneous according to past academic achievement tended to have significantly higher subsequent academic achievement and self-esteem. Results revealed no variation attributable to each student's gender and IQ in the effects of ability grouping. 相似文献

The present study compared the relative effects of hands-on and teacher demonstration laboratory methods on declarative knowledge (factual and conceptual) and procedural knowledge (problem-solving) achievement. Of particular interest were (a) whether these relationships vary as a function of reasoning ability and (b) whether prior knowledge and reasoning ability predict student achievement. Ninth-grade physical science students were randomly assigned to classes taught by either a hands-on or a teacher demonstration laboratory method. Students' reasoning ability and prior knowledge of science were assessed prior to the instruction. The two instructional methods resulted in equal declarative knowledge achievement. However, students in the hands-on laboratory class performed significantly better on the procedural knowledge test than did students in the teacher demonstration class. These results were unrelated to reasoning ability. Prior knowledge significantly predicted performance on the declarative knowledge test. Both reasoning ability and prior knowledge significantly predicted performance on the procedural knowledge test, with reasoning ability being the stronger predictor. 相似文献

This study examined 10th‐grade students' use of theory and evidence in evaluating a socio‐scientific issue: the use of underground water, after students had received a Science, Technology and Society‐oriented instruction. Forty‐five male and 45 female students from two intact, single‐sex, classes participated in this study. A flow‐map method was used to assess the participants' conceptual knowledge. The reasoning mode was assessed using a questionnaire with open‐ended questions. Results showed that, although some weak to moderate associations were found between conceptual organization in memory and reasoning modes, the students' ability to incorporate theory and evidence was in general inadequate. It was also found that students' reasoning modes were consistent with their epistemological perspectives. Moreover, male and female students appear to have different reasoning approaches. 相似文献

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.

Using a multilevel approach, this study examined the role of classroom emotional climate on students' academic achievement. Positive and negative emotions and homeroom teachers' support were used to assess the classroom emotional climate on the individual and class levels. To our knowledge, no study to date has investigated these specific aspects of the classroom emotional climate in relation to students' GPA. Data were collected from 73 classrooms in grades 7‐12 (N = 1,641, students; 53% female) across three schools in Israel. Findings revealed that aggregated levels of both positive affect and perceived homeroom teacher support were positively tied to GPA and that aggregated levels of negative affect were negatively tied to GPA. The final model included gender, teacher support, individual and class emotions and explained 14% of within‐class GPA. A central implication of this study is the relevance of having an emotionally supportive homeroom teacher for students' academic achievement. 相似文献

The purpose of this study was to explore relationships among school students' (N = 189) meaningful learning orientation, reasoning ability and acquisition of meaningful understandings of genetics topics, and ability to solve genetics problems. This research first obtained measures of students' meaningful learning orientation (meaningful and rote) and reasoning ability (preformal and formal). Students were tested before and after laboratory-based learning cycle genetics instruction using a multiple choice assessment format and an open-ended assessment format (mental model). The assessment instruments were designed to measure students' interrelated understandings of genetics and their ability to solve and interpret problems using Punnett square diagrams. Regression analyses were conducted to examine the predictive influence of meaningful learning orientation, reasoning ability, and the interaction of these variables on students' performance on the different tests. Meaningful learning orientation best predicted students' understanding of genetics interrelationships, whereas reasoning ability best predicted their achievement in solving genetics problems. The interaction of meaningful learning orientation and reasoning ability did not significantly predict students' genetics understanding or problem solving. Meaningful learning orientation best predicted students' performance on all except one of the open-ended test questions. Examination of students' mental model explanations of meiosis, Punnett square diagrams, and relationships between meiosis and the use of Punnett square diagrams revealed unique patterns in students' understandings of these topics. This research provides information for educators on students' acquisition of meaningful understandings of genetics. © 1996 John Wiley & Sons, Inc. 相似文献

Applying knowledge from one context to another is a notoriously difficult problem, both for children and adults, but lies at the heart of educational endeavors. Analogical reasoning is a cognitive underpinning of the ability to notice and draw similarities across contexts. Reasoning by analogy is especially challenging for students, who must transfer in the context‐rich and often high‐pressure settings of classrooms. In this brief article, we explore how best to facilitate children's analogical reasoning, with the aim of providing practical suggestions for classroom instruction. We first discuss what is known about the development and neurological underpinnings of analogical reasoning, and then review research directly relevant to supporting analogical reasoning in classroom contexts. We conclude with concrete suggestions for educators that may foster their students' spontaneous analogical reasoning and thereby enhance scholastic achievement. 相似文献

Cognitive foundations for science assessment design: Knowing what students know about evolution 总被引：1，自引：0，他引：1
To improve assessments of academic achievement, test developers have been urged to use an “assessment triangle” that starts with research‐based models of cognition and learning [NRC (2001) Knowing what students know: The science and design of educational assessment. Washington, DC: National Academy Press]. This approach has been successful in designing high‐quality reading and math assessments, but less progress has been made for assessments in content‐rich sciences such as biology. To rectify this situation, we applied the “assessment triangle” to design and evaluate new items for an instrument (ACORNS, Assessing Contextual Reasoning about Natural Selection) that had been proposed to assess students' use of natural selection to explain evolutionary change. Design and scoring of items was explicitly guided by a cognitive model that reflected four psychological principles: with development of expertise, (1) core concepts facilitate long‐term recall, (2) causally‐central features become weighted more strongly in explaining phenomena, (3) normative ideas co‐exist but increasingly outcompete naive ideas in reasoning, and (4) knowledge becomes more abstract and less specific to the learning situation. We conducted an evaluation study with 320 students to examine whether scores from our new ACORNS items could detect gradations of expertise, provide insight into thinking about evolutionary change, and predict teachers' assessments of student achievement. Findings were consistent with our cognitive model, and ACORNS was revealing about undergraduates' thinking about evolutionary change. Results indicated that (1) causally‐central concepts of evolution by natural selection typically co‐existed and competed with the presence of naïve ideas in all students' explanations, with naïve ideas being especially prevalent in low‐performers' explanations; (2) causally‐central concepts were elicited most frequently when students were asked to explain evolution of animals and familiar plants, with influence of superficial features being strongest for low‐performers; and (3) ACORNS scores accurately predicted students' later achievement in a college‐level evolution course. Together, findings illustrate usefulness of cognitive models in designing instruments intended to capture students' developing expertise. © 2012 Wiley Periodicals, Inc.

This study addressed the question of how to increase students' competencies for regulating their co‐construction of knowledge when tackling complex collaborative learning tasks which are increasingly emphasized as a dimension of educational reform. An intervention stressing the metacognitive, regulatory, and strategic aspects of knowledge co‐construction, called Thinking Aloud Together, was embedded within a 12‐week science unit on building mental models of the nature of matter. Four classes of eighth graders received the intervention, and four served as control groups for quantitative analyses. In addition, the interactions of 24 students in eight focal groups were profiled qualitatively, and 12 of those students were interviewed twice. Students who received the intervention gained in metacognitive knowledge about collaborative reasoning and ability to articulate their collaborative reasoning processes in comparison to students in control classrooms, as hypothesized. However, the treatment and control students did not differ either in their abilities to apply their conceptual knowledge or in their on‐line collaborative reasoning behaviors in ways that were attributable to the intervention. Thus, there was a gap between students' metacognitive knowledge about collaborative cognition and their use of collaborative reasoning skills. Several reasons for this result are explored, as are patterns relating students' outcomes to their perspectives on learning science. © 1999 John Wiley & Sons, Inc.

This study compares 183 high school chemistry students' applied and theoretical knowledge of selected concepts based on the particulate theory. The concepts are dissolution, diffusion, effusion, and states of matter. A two-form instrument called the Physical Changes Concepts Test (PCCT) was developed for this study. The application form measures students' knowlege using everyday language. The theoretical form measures students' knowledge using scientific language. Students' formal reasoning ability was measured using the Test Of Logical Thinking (TOLT). The overall results of the two forms of the PCCT indicate that more than 40% of the students displayed alternative conceptions (ACs) of the concepts covered in the PCCT. The study found that students' formal reasoning ability and their preexisting knowledge are associated with their conceptions and use of the particulate theory. The analysis of the nature of students' ACs and their use of the particulate theory revealed a significant difference between students' applied and theoretical knowledge. 相似文献

This study investigated gender inequality in biology lessons and analysed the effects of the observed inequality on students' short-term knowledge achievement, situational interest and students' evaluation of teaching (SET). Twenty-two biology teachers and 803 7th-grade students from rural and urban classrooms in China participated in the study. Each teacher was videotaped for 1 lesson on the topic blood and circulatory system. Before and after the lessons, the students completed tests and questionnaires. Chi-square analysis was conducted to compare the boys' and girls' participation rates of answering teachers' questions in the lessons. The findings revealed that in the urban classrooms the boys had a significantly higher rate of participation than did the girls, and hence also a higher situational interest. However, no such gender inequity was found among the rural students. The study also revealed that urban students answered more complicated questions compared with the rural students in general. The findings of this study suggest that the teachers should try to balance boys' and girls' participation and involve more students in answering questions in their lessons. The study also raises questions about long-term effects of students' participation in answering teachers' questions on their outcomes-knowledge achievement, situational interest and SET. 相似文献

This study explored factors predicting the extent to which high school students (N = 140) acquired meaningful understanding of the biological topics of meiosis, the Punnett-square method, and the relationships between these topics. This study (a) examined mental modeling as a technique for measuring students' meaningful understanding of the topics, (b) measured students' predisposed, generalized tendency to learn meaningfully (meaningful learning orientation), (c) determined the extent to which students' meaningful learning orientation predicted meaningful understanding beyond that predicted by aptitude and achievement motivation, (d) experimentally tested two instructional treatments (relationships presented to students, relationships generated by students), (e) explored the relationships of meaningful learning orientation, prior knowledge, instructional treatment, and all interactions of these variables in predicting meaningful understanding. The results of correlations and multiple regressions indicated that meaningful learning orientation contributed to students' attainment of meaningful understanding independent of aptitude and achievement motivation. Meaningful learning orientation and prior knowledge interacted in unique ways for each topic to predict students' attainment of meaningful understanding. Instructional treatment had relatively little relationship to students' acquisition of meaningful understanding, except for learners midrange between meaningful and rote. These findings imply that a meaningful learning approach among students may be important, perhaps as much or more than aptitude and achievement motivation, for their acquisition of interrelated, meaningful understandings of science. 相似文献

In this study, a two‐tier diagnostic test for understanding malaria was developed and administered to 314 Bruneian students in Year 12 and in a nursing diploma course. The validity, reliability, difficulty level, discriminant indices, and reading ability of the test were examined and found to be acceptable in terms of measuring students' understanding and identifying alternative conceptions with respect to malaria. Results showed that students' understanding of malaria was high for content, low for reasons, and limited and superficial for both content and reasons. The instrument revealed several common alternative conceptual understandings students' hold about malaria. The MalariaTT2 instrument developed could be used in classroom lessons for challenging alternative conceptions and enhancing conceptions of malaria. 相似文献

This study investigated the simultaneous impact of demographic, personality, intelligence, and (prior) study performance factors on students' academic achievement in a three-year academic problem-based psychology program. Information regarding students' gender, age, nationality, pre-university education, high school grades, Big Five personality traits, intelligence (i.e., numerical, verbal, spatial), observed learning activities, and self-study time was collected among almost 1800 students enrolled in this psychology bachelor program at Erasmus University Rotterdam between 2003 and 2009. Academic achievement was measured by students' yearly number of acquired credit points, a course test, and a knowledge progress test. Multiple regression analyses showed that observed learning activities, first- and second-year performance, high school grades, conscientiousness, and verbal ability were most strongly and consistently related to academic achievement in the bachelor. Other student factors also contributed to academic achievement, but their influence was less prominent and mainly restricted to the first year. These results suggest that (prior) educational achievements and observable learning activities are most important for academic success in a problem-based learning bachelor program. 相似文献

Students in a large one-semester nonmajors college biology course were classified into one of three groups (intuitive—I, transitional—T, reflective—R) based upon a pretest of scientific reasoning ability. Laboratory teams of two students each then were formed, such that all possible combinations of reasoning abilities were represented (i.e., I-I, I-T, I-R, T-T, T-R, R-R). Students worked with their assigned partners during each of the course's 14 laboratory sessions. Gains in reasoning ability, laboratory achievement, and course achievement, as well as changes in students' opinions of their motivation, enjoyment of the laboratory, and their own and their partner's reasoning abilities were assessed at the end of the semester. Significant pre- to posttest gains in reasoning ability by the intuitive and transitional students were found, but these gains were not significantly related to the laboratory partner's reasoning ability. Also, course achievement was not significantly related to the laboratory partner's reasoning ability. Students were perceptive of others' reasoning ability; the more able reasoners were generally viewed as being more motivated, having better ideas, and being better at doing science. Additional results also indicated that course enjoyment and motivation was significantly decreased for the transitional students when they were paired with intuitive students. Apparently, for students in transition (i.e., not at an equilibrium state with regard to reasoning level), it is frustrating to work with a less able reasoner. However, some evidence was found to suggest that reflective students may benefit from working with a less able partner. 相似文献

This study examined test-related experiences of enjoyment, anger, anxiety, and boredom in a sample of 2059 German school students (50% female) from grade 6, and how they relate to students' abstract reasoning ability (ARA). Emotions were assessed immediately before, during, and after a mathematics achievement test. Analysis of variance showed that emotions experienced during the test situation differed based on students' ARA level, with correspondence analysis revealing substantial differences between the emotional profiles of different ability groups. Enjoyment proved to be most prominent in students with high ARA, whereas anger and anxiety were predominant for students with low ARA. Boredom was found to be highest among students in the intermediate ARA group. Implications for research and practice are discussed. 相似文献

Prior research has shown that game-based learning tools, such as DragonBox 12+, support algebraic understanding and that students' in-game progress positively predicts their later performance. Using data from 253 seventh-graders (12–13 years old) who played DragonBox as a part of technology intervention, we examined (a) the relations between students' progress within DragonBox and their algebraic knowledge and general mathematics achievement, (b) the moderating effects of students' prior performance on these relations and (c) the potential factors associated with students' in-game progress. Among students with higher prior algebraic knowledge, higher in-game progress was related to higher algebraic knowledge after the intervention. Higher in-game progress was also associated with higher end-of-year mathematics achievement, and this association was stronger among students with lower prior mathematics achievement. Students' demographic characteristics, prior knowledge and prior achievement did not significantly predict in-game progress beyond the number of intervention sessions students completed. These findings advance research on how, for whom and in what contexts game-based interventions, such as DragonBox, support mathematical learning and have implications for practice using game-based technologies to supplement instruction.
Practitioner notes
What is already known about this topic- DragonBox 12+ may support students' understanding of algebra but the findings are mixed.
- Students who solve more problems within math games tend to show higher performance after gameplay.
- Students' engagement with mathematics is often related to their prior math performance.
- For students with higher prior algebraic knowledge, solving more problems in DragonBox 12+ is related to higher algebraic performance after gameplay.
- Students who make more in-game progress also have higher mathematics achievement, especially for students with lower prior achievement.
- Students who spend more time playing DragonBox 12+ make more in-game progress; their demographic, prior knowledge and prior achievement are not related to in-game progress.
- DragonBox 12+ can be beneficial as a supplement to algebra instruction for students with some understanding of algebra.
- DragonBox 12+ can engage students with mathematics across achievement levels.
- Dedicating time and encouraging students to play DragonBox 12+ may help them make more in-game progress, and in turn, support math learning.

This study was designed to identify and analyze possible factors that mediate the effect of gender on ninth‐grade Turkish students' misconceptions concerning electric circuits. A Simple Electric Circuit Concept Test (SECCT), including items with both practical and theoretical contexts, and an Interest‐Experience Questionnaire about Electricity (IEQ) were administered to 1,678 ninth‐grade students (764 male, 914 female) after the completion of a unit on electricity to assess students' misconceptions and interests‐experiences about electricity. Results of the concept test indicated that general performances of the students were relatively low and that many students had misconceptions in interpreting electric circuits. When the data were analyzed using MANOVA and follow‐up ANOVAs, a gender difference for males was observed on the dependent variable of total scores on the 10 practical items; however, there was no significant gender difference on the dependent variable of total scores on the six theoretical items. Moreover, when the same data were analyzed using MANCOVA and follow‐up ANCOVAs, controlling students' age and interest‐experience related to electricity, the observed gender difference was mediated on the total scores on the practical items. © 2004 Wiley Periodicals, Inc.
