This study examined the impact of cooperative learning activities on student achievement and attitudes in large-enrollment (>250) introductory biology classes. We found that students taught using a cooperative learning approach showed greater improvement in their knowledge of course material compared with students taught using a traditional lecture format. In addition, students viewed cooperative learning activities highly favorably. These findings suggest that encouraging students to work in small groups and improving feedback between the instructor and the students can help to improve student outcomes even in very large classes. These results should be viewed cautiously, however, until this experiment can be replicated with additional faculty. Strategies for potentially improving the impact of cooperative learning on student achievement in large courses are discussed.  相似文献

Student epistemic preferences have been found to be important in student learning and achievement. The present study proposed a new conceptualization of student epistemic preferences in the epistemic match model, assessed the match between student epistemic beliefs about chemistry and their epistemic preferences, and, most importantly, examined how this epistemic match may be associated with chemistry course achievement. We adopted latent class analysis and found three distinct profiles of epistemic preferences based on the dimensions of simple and certain knowledge, attainable truth, and alternative knowledge claims. Students in Latent Class 3 (Moderate Preferences) demonstrated the closest match between chemistry epistemic beliefs and epistemic preferences, and had more students who obtained higher grades and fewer students who had lower grades in an introductory chemistry course compared to the other two classes. Students in Latent Classes 1 (All Preferred) and 2 (Alternative-Claim Disliked), however, demonstrated certain degrees of epistemic mismatch between chemistry epistemic beliefs and epistemic preferences, and had noticeably lower achievement in the chemistry course. The study findings highlight the importance of achieving a close match between epistemic beliefs and epistemic preferences for higher achievement in a subject domain.  相似文献

We investigate the relationship between teacher licensure test scores and student test achievement and high school course-taking. We focus on three subject/grade combinations—middle school math, ninth-grade algebra and geometry, and ninth-grade biology—and find evidence that a teacher's basic skills test scores are modestly predictive of student achievement in middle school math and highly predictive of student achievement in high school biology. A teacher's subject-specific licensure test scores are a consistent and statistically significant predictor of student achievement only in high school biology. Finally, we find little evidence that students assigned to middle school teachers with higher basic-skills test scores are more likely to take advanced math and science courses in high school.  相似文献

Inquiry-based curricula are an essential tool for reforming science education yet the role of the teacher is often overlooked in terms of the impact of the curriculum on student achievement. Our research focuses on 22 teachers’ use of a year-long high school urban ecology curriculum and how teachers’ self-efficacy, instructional practices, curricular enactments and previous experience impacted student learning. Data sources included teacher belief surveys, teacher enactment surveys, a student multiple-choice assessment focused on defining and identifying science concepts and a student open-ended assessment focused on scientific inquiry. Results from the two hierarchical linear models indicate that there was significant variation between teachers in terms of student achievement. For the multiple-choice assessment, teachers who spent a larger percentage of time on group work and a smaller percentage of time lecturing had greater student learning. For the open-ended assessment, teachers who reported a higher frequency of students engaging in argument and sharing ideas had greater student learning while teachers who adapted the curriculum more had lower student learning. These results suggest the importance of supporting the active role of students in instruction, emphasising argumentation, and considering the types of adaptations teachers make to curriculum.  相似文献

Elementary teachers play a crucial role in supporting and scaffolding students’ model-based reasoning about natural phenomena, particularly complex systems such as the water cycle. However, little research exists to inform efforts in supporting elementary teachers’ learning to foster model-centered, science learning environments. To address this need, we conducted an exploratory multiple-case study using qualitative research methods to investigate six 3rd-grade teachers’ pedagogical reasoning and classroom instruction around modeling practices (construct, use, evaluate, and revise) and epistemic considerations of scientific modeling (generality/abstraction, evidence, mechanism, and audience). Study findings show that all teachers emphasized a subset of modeling practices—construction and use—and the epistemic consideration of generality/abstraction. There was observable consistency between teachers’ articulated conceptions of scientific modeling and their classroom practices. Results also show a subset of the teachers more strongly emphasized additional epistemic considerations and, as a result, better supported students to use models as sense-making tools as well as representations. These findings provide important evidence for developing elementary teacher supports to scaffold students’ engagement in scientific modeling.  相似文献

In flipped classrooms, lectures, which are normally delivered in-class, are assigned as homework in the form of videos, and assignments that were traditionally assigned as homework, are done as learning activities in class. It was hypothesized that the effectiveness of the flipped model hinges on a student’s desire and ability to adopt a self-directed learning style. The purpose of this study was twofold; it aimed at examining the relationship between two variables—students’ perceptions of the flipped model and their self-regulated learning (SRL) behaviors—and the impact that these variables have on achievement in a flipped class. For the study, 76 participants from a flipped introductory biology course were asked about their SRL strategy use and perceptions of the flipped model. SRL strategy use was measured using a modified version of the Motivated Strategies for Learning Questionnaire (MSLQ; Wolters et al. 2005), while the flipped perceptions survey was newly derived. Student letter grades were collected as a measure of achievement. Through regression analysis, it was found that students’ perceptions of the flipped model positively predict students’ use of several types of SRL strategies. However, the data did not indicate a relationship between student perceptions and achievement, neither directly nor indirectly, through SRL strategy use. Results suggest that flipped classrooms demonstrate their successes in the active learning sessions through constructivist teaching methods. Video lectures hold an important role in flipped classes, however, students may need to practice SRL skills to become more self-directed and effectively learn from them.  相似文献

This study examined the role of computer-supported knowledge-building discourse and epistemic reflection in promoting elementary-school students’ scientific epistemology and science learning. The participants were 39 Grade 5 students who were collectively pursuing ideas and inquiry for knowledge advance using Knowledge Forum (KF) while studying a unit on electricity; they also reflected on the epistemic nature of their discourse. A comparison class of 22 students, taught by the same teacher, studied the same unit using the school’s established scientific investigation method. We hypothesised that engaging students in idea-driven and theory-building discourse, as well as scaffolding them to reflect on the epistemic nature of their discourse, would help them understand their own scientific collaborative discourse as a theory-building process, and therefore understand scientific inquiry as an idea-driven and theory-building process. As hypothesised, we found that students engaged in knowledge-building discourse and reflection outperformed comparison students in scientific epistemology and science learning, and that students’ understanding of collaborative discourse predicted their post-test scientific epistemology and science learning. To further understand the epistemic change process among knowledge-building students, we analysed their KF discourse to understand whether and how their epistemic practice had changed after epistemic reflection. The implications on ways of promoting epistemic change are discussed.  相似文献

The authors examined the effects of six types of teacher professional learning activities on student achievement growth over 4 years using statewide longitudinal survey data collected from 467 middle school mathematics teachers in 91 schools merged with 11,192 middle school students' mathematics scores in a standardized assessment in Missouri. The data showed that teacher-centered collaborative activities to learn about mathematics teaching and learning (teacher collaboration and informal communication) seem to be more effective in improving student mathematics achievement than learning activities that do not necessarily involve such teacher-centered collaborative opportunities (professional development programs, university courses, individual learning activities). Teacher-driven research activities through professional conference presentation and participation were also found to be associated with student achievement growth in mathematics. The districts and schools may benefit from investing their professional development funds and resources in facilitating teacher-centered collaborative and research-based learning activities in order to improve student learning.  相似文献

This study assessed the perceptions of 146 gifted and 115 non-gifted high school biology students and investigated associations between student perceptions and cognitive achievement. The What Is Happening In this Class? (WIHIC) was used to assess perceptions of actual and preferred learning environments. Data indicated that all students preferred a more favourable environment than the one that they were currently experiencing, but gifted students perceived their actual environment more positively than non-gifted students. Statistically significant associations between the actual learning environment and achievement on a standardised biology test were found for the majority of scales. Teacher Support, Investigation and Equity were all statistically significant independent predictors of student achievement, while Student Cohesiveness had a negative association with achievement. Interviews revealed that students interpreted some WIHIC items differently from how the developers had intended.  相似文献

A key stimulus of learning efficacy for students in the classroom is active participation and engagement in the learning process. This study examines the nature of teacher–student and student–student discourse when leveraged by an interactive technology—Group Scribbles (GS) in a Primary 5 Science classroom in Singapore which supports rapid collaborative knowledge building (RCKB). We envisaged nine design principles for RCKB in the design of lessons and postulated a logic model that links and explains the effects of our design principles to the ultimate goal of learning efficacy. We presented a case study of a GS lesson which shows that GS affordances leveraged by good lesson and activity design could enable the students to have more epistemic agency. Students had opportunities to participate spontaneously in class discussions by fully expressing their ideas without inhibition. The technology effect is used to support instant formative feedback and interactions among students effectively.  相似文献

The need for supporting student writing has received much attention in writing research. One specific type of support is feedback—including peer feedback—on the writing process. Despite the wealth of literature on both feedback and academic writing, there is little empirical evidence on what type of feedback best promotes writing in online environments. This article reports on research that tries to determine what type of feedback best improves the quality of collaborative writing and what the effects of feedback are on student learning in an environment based on asynchronous written communication. The results reveal that concerning the type of feedback, epistemic feedback or epistemic and suggestive feedback best improve the quality of collaborative writing performance. The nature of the feedback-giver (whether teacher feedback or teacher and peer) makes a difference to the final text only when the feedback is epistemic, or epistemic and suggestive.  相似文献

There is an increasing use of mobile technologies in the classroom, particularly its use in supporting contextual learning, but comparative research on the effects of mobile learning in mathematics are few. The aim of this research was to examine student perceptions of using mobile technologies and their effect on mathematics achievement in a randomised controlled trial. Seventy-four Grade 5 and 6 students and three teachers participated in the study. Both groups participated in six weeks of active and collaborative learning activities on math. The experimental group used tablets to support them in their activities while the control group had similarly designed activities without the tablets. The tablets were observed to have facilitated constructivist learning activities as students moved in and out of different learning contexts. Most of the experimental group had positive evaluations but their end activity ratings were not significantly different from the control group. Gender differences were found in terms of how students perceived the mobile learning activities. There was no difference found in the groups’ post-test achievement scores following an analysis of covariance with pre-test as covariate. For items relating to student misconception, students in the experimental group performed better. Overall, the study highlights that the success of a mobile learning intervention is dependent on various factors, such as student characteristics, stability of the technology and content compatibility. Implications for practice and future research are discussed.  相似文献

Evidence of a gap in student understanding has been well documented in chemistry: the typical student holds an abundance of misconceptions. The current expectation is that educational reform will foster greater student achievement via inquiry teaching within classrooms. Using assessments involving both conceptual and algorithmic knowledge of gas behaviour, gas laws, and phase changes in chemistry, this study aims to determine the relationship between inquiry teaching and student achievement. The topics were tested in the context of a unit from a reform‐based curriculum that features inquiry, hands‐on activities, and cooperative learning. This curriculum provides step‐by‐step guidance for each lesson in the teacher materials, in order to promote quality inquiry teaching. Two schools were involved in this study, with two high school chemistry teachers from each school. Each teacher participated in professional development and implemented this curriculum with sufficient training and guidance to develop reform methods. Student achievement was found to positively correlate with the use of inquiry teaching about the assessed concepts, regardless of teacher experience or school context.  相似文献

Relations were examined between epistemic beliefs, achievement goals, learning strategies, and achievement. We sought to empirically test Muis’ [Muis, K. R. (2007). The role of epistemic beliefs in self-regulated learning. Educational Psychologist, 42, 173–190] hypothesis that epistemic beliefs influence processes of self-regulated learning via the standards students set for learning once goals are produced. Two hundred one undergraduate students from an educational psychology course completed questionnaires designed to measure the various constructs. Students’ final grades were also collected at the end of the semester. Students’ recollections of course tasks revealed that their epistemic beliefs are activated during learning. Results from structural equation modeling revealed epistemic beliefs influenced the types of achievement goals students adopted, which subsequently influenced the types of learning strategies they used in their education course, and their achievement. Moreover, achievement goals mediated relations between epistemic beliefs and learning strategies, and learning strategies mediated relations between achievement goals and achievement.  相似文献

In this study, a hypothesised model with latent variables such as socio‐economic status, students’ perception of success and interest in different subject matter areas, out‐of‐school activities, and classroom teaching learning activities in relation to science achievement of the students was tested via linear structural modelling. The data come from the Student Assessment Program—2002 conducted by the Ministry of National Education in Turkey. The results obtained in a sample of 29,911 students indicated that there were positive relationships between the socio‐economic status of the students and teacher‐centred activities in the classroom with science achievement. On the other hand, student‐centred activities did not contribute to explain achievement measures positively. There is a need to scrutinise the quality of student‐centred activities in Turkey.  相似文献

ABSTRACT

The author sought to investigate the effects of inquiry-based science instruction on science achievement and interest in science of 5,120 adolescents from 85 schools in Qatar. Results of hierarchical linear modeling analyses revealed the substantial positive effects of science teaching and learning with a focus on model or applications and interactive science teaching and learning on science achievement and interest in science. In contrast, science teaching and learning using student investigations and hands-on activities had substantial negative effects on science achievement in the context of other variables. Implications of the findings for educational policy and classroom practice are discussed.  相似文献

In a flipped classroom model, learning of basic content is shifted before class while in-class time is used for concept application. Empirical and controlled research studies are lacking on the best strategies to provide the necessary pre-class content instruction. In this study, we tested three methods of pre-class content learning—interactive online tutorials, video lectures, and textbook-style readings—while holding the content and the in-class application activities constant. Identical introductory, non-majors biology classes were manipulated at both a public, open-enrollment institution and a private, highly selective institution. We found that video lectures offer a small advantage to overall student learning over interactive tutorials or textbook-style readings. Although our two populations differed in their ability to effectively learn from pre-class activities, through a student-centered flipped classroom approach, students at both institutions demonstrated equal learning gains by the final assessment. Potential reasons for some observed differences are suggested.  相似文献

The aim of this study was to investigate the relationships between students?? epistemic beliefs in biology and their approaches to learning biology. To this end, two instruments, the epistemic beliefs in biology and the approaches to learning biology surveys, were developed and administered to 520 university biology students, respectively. By and large, it was found that the students reflected ??mixed?? motives in biology learning, while those who had more sophisticated epistemic beliefs tended to employ deep strategies. In addition, the results of paired t tests revealed that the female students were more likely to possess beliefs about biological knowledge residing in external authorities, to believe in a right answer, and to utilize rote learning as a learning strategy. Moreover, compared to juniors and seniors, freshmen and sophomores tended to hold less mature views on all factors of epistemic beliefs regarding biology. Another comparison indicated that theoretical biology students (e.g. students majoring in the Department of Biology) tended to have more mature beliefs in learning biology and more advanced strategies for biology learning than those students studying applied biology (e.g. in the Department of Biotechnology). Stepwise regression analysis, in general, indicated that students who valued the role of experiments and justify epistemic assumptions and knowledge claims based on evidence were more oriented towards having mixed motives and utilizing deep strategies to learn biology. In contrast, students who believed in the certainty of biological knowledge were more likely to adopt rote learning strategies and to aim to qualify in biology.  相似文献

We implemented a "how to study" workshop for small groups of students (6-12) for N = 93 consenting students, randomly assigned from a large introductory biology class. The goal of this workshop was to teach students self-regulating techniques with visualization-based exercises as a foundation for learning and critical thinking in two areas: information processing and self-testing. During the workshop, students worked individually or in groups and received immediate feedback on their progress. Here, we describe two individual workshop exercises, report their immediate results, describe students' reactions (based on the workshop instructors' experience and student feedback), and report student performance on workshop-related questions on the final exam. Students rated the workshop activities highly and performed significantly better on workshop-related final exam questions than the control groups. This was the case for both lower- and higher-order thinking questions. Student achievement (i.e., grade point average) was significantly correlated with overall final exam performance but not with workshop outcomes. This long-term (10 wk) retention of a self-testing effect across question levels and student achievement is a promising endorsement for future large-scale implementation and further evaluation of this "how to study" workshop as a study support for introductory biology (and other science) students.  相似文献
