This replication studied the effect of two specific classroom climates on learning of science process skills and content achievement in college science classes. Two classroom climates were established and designated as discovery classroom climate (DCC) and nondiscovery classroom climate (NDCC). The term discovery denotes the degree of freedom the teacher established in classroom interactions, both verbal and nonverbal. Verbal interactions were monitored with the Science Laboratory Interaction Categories. These data indicate that students in the two classroom climates achieved equally as well on learning of biological content of the course and on scores in science process skills as measured by the Welch Science Process Inventory. This study indicates students in the less directive discovery climate learned as much content as a more directive comparison class—they lost nothing of what is traditionally sought in a college science class. Differences between the original and the replication study on the Science Process Inventory were noted.  相似文献

ABSTRACT

The purpose of this study was to examine community college engineering students’ perceptions of their classroom climate and how these perceptions are related to fundamental skills in engineering. The study was guided by the following research question: How are community college engineering students’ perceptions of their fundamental engineering skills related to their perceptions of classroom climate? Data from a 2009 National Science Foundation sponsored project, Prototype to Production: Processes and Conditions for Preparing the Engineer of 2020 (P2P), which contains information from students in 15 pre-engineering community college programs, were examined. Measures of classroom climate and fundamental skills related to engineering were first established through an exploratory factor analysis. In order to explore differences in student perceptions by individual characteristics and by institution, hierarchical linear modeling (HLM) was used. Results indicated that for community college engineering students, a warmer perception of classroom climate was associated with a higher perception of fundamental engineering skills. At community colleges, class sizes are generally smaller, especially compared to introductory courses at universities, and may provide a warmer climate for students considering beginning their engineering degrees. Given the diversity within community colleges, these institutions may provide an important pathway for underrepresented groups in engineering.  相似文献

Undergraduate college “science partners” provided content knowledge and a supportive atmosphere for K–5 teachers in a university–school professional development partnership program in science instruction. The Elementary Science Education Partners program, a Local Systemic Change initiative supported by the National Science Foundation, was composed of four major elements: 1) a cadre of mentor teachers trained to provide district-wide teacher professional development; 2) a recruitment and training effort to place college students in classrooms as science partners in semester-long partnerships with teachers; 3) a teacher empowerment effort termed “participatory reform”; and 4) an inquiry-based curriculum with a kit distribution and refurbishment center. The main goals of the program were to provide college science students with an intensive teaching experience and to enhance teachers'' skills in inquiry-based science instruction. Here, we describe some of the program''s successes and challenges, focusing primarily on the impact on the classroom teachers and their science partners. Qualitative analyses of data collected from participants indicate that 1) teachers expressed greater self-confidence about teaching science than before the program and they spent more class time on the subject; and 2) the college students modified deficit-model negative assumptions about the children''s science learning abilities to express more mature, positive views.  相似文献

Differences in classroom climate and science related attitudes were investigated among junior high school science classes and students in Taiwan. The sample consisted of 1,269 students enrolled in 40 science classes distributed equally among ten junior high schools, five metropolitan and five rural. Classes were further classified according to sex (21 boys and 19 girls classes) and ability (19 high and 21 low ability classes). Using the Learning Environment Inventory (Anderson, Walberg, & Fraser, 1982) to measure climate, science classes in metropolitan schools, more than rural, were found to be characterized by Speed, Friction, Favoritism, Difficulty, Cliqueness, and Competitiveness. No differences were found in the classroom climates of classes in which students were grouped according to sex or ability. Using the Test of Science-Related Attitudes (Fraser, 1981), students in science classes in metropolitan schools, in contrast to rural, expressed more positive attitudes toward the Social Implications of Science, Adoption of Scientific Attitudes, and Attitude to Scientific Inquiry. Boys more than girls recorded high scores on Leisure Interest in Science and Career Interest in Science. High ability students were found to have higher scores on Attitude to Scientific Inquiry than did low ability students. When examining the relationship between the 15 subscale scores of the LEI and the seven subscale scores of the TOSRA for the 40 classes, only 9 out of 105 correlations proved to be significant. Most differences in climate, attitude, and their interactions were attributed to school location rather than to student characteristics.  相似文献

Abstract

This study sought to assess the actual and ideal social climate of an undergraduate social science class for educators, and to utilize this information to structure a subsequent class on the same topic. It was hypothesized that a classroom climate more closely approaching an "ideal^ one would facilitate better course appreciation, involvement, and attendance. Modifications in course social climate as suggested by "Class A" markedly improved the social climate of "Class B" as reported by class members. Improved congruence between real and ideal climates was linked to significantly greater appreciation of class functioning, class content, overall course appreciation, and greater class attendance. As students reported similar amounts of task orientation in each class, it was argued the classroom social climate may contribute an independent and malleable feature of the classroom setting which an instructor can use to his/her advantage.  相似文献

In classrooms from kindergarten to graduate school, researchers have identified target students as students who monopolize material and human resources. Classroom structures that privilege the voice and actions of target students can cause divisive social dynamics that may generate cliques. This study focuses on the emergence of target students, the formation of cliques, and professors' efforts to mediate teacher learning in a Master of Science in Chemistry Education (MSCE) program by structuring the classroom environment to enhance nontarget students' agency. Specifically, we sought to answer the following question: What strategies could help college science professors enact more equitable teaching structures in their classrooms so that target students and cliques become less of an issue in classroom interactions? The implications for professional education programs in science and mathematics include the need for professors to consider the role and contribution of target students to the learning environment, the need to structure an equitable learning environment, and the need to foster critical reflection upon classroom interactions between students and instructors. © 2006 Wiley Periodicals, Inc.

Reading is a communication process that is crucial to students in science. Printed text materials are the most widely used teacher aids in the classroom. But reading as a major focus of science instruction has been out of favor with the mainstream of science education since the late 1950s. Despite this, few would deny the value of reading skills in a science class. The purpose of the present investigation was to determine how the use of Newsday's Science Education Series Program affected selected ninth-grade students' comprehension of science reading material. Analysis of covariance showed that students with standardized reading and mathematics scores at least two years above grade level who were taught using newspaper science articles alone had Degrees of Reading Power posttest scores higher at the 0.05 level of significance compared to students taught using Newsday's Science Education Series Program or using only the science article's content as part of class lessons. Students with standardized reading and mathematics scores on grade level taught using Newsday's Science Education Series Program had Degrees of Reading Power posttest scores higher at the 0.01 level of significance compared to students taught by either of the other methods.  相似文献

The Next Generation Science Standards (NGSS) strives to shift science learning from the teacher as a single cognitive agent, to a classroom community in which participants are working together in directing the classroom's communal knowledge to figure out questions about how phenomena occur, and building, testing, and refining their ideas to address those questions. To achieve this type of classroom environment, teachers should attend to students' knowledge and ideas and pay attention to how students are located within teacher-led interactions, such as being positioned as active discussants or designated listeners. In this study, we explore if and how this is occurring in the NGSS era. We used a naturalistic inquiry to explore how an experienced first-grade teacher used a new NGSS-aligned unit that called for students to use the science and engineering practices (SEP) to build content knowledge. We used a macro-analytic lens to answer the research question “how are class discussions shaped to address the SEP”? We used a micro-analytic lens to answer the research question “how are students positioned during these science discussions in this classroom?” Evidence suggests that the teachers' whole class discussions incorporated and involved the SEP which were specified in the unit lessons for content learning. However, on a micro-analytic level, we found that few students were positioned as active discussants. The teacher heavily relied on those students who could provide succinct and clearly relevant answers while positioning the remainder of the students as silent spectators. Implications from this research suggest that not only new NGSS curriculum materials need to focus on what students should know and do but they also need to address heuristics for teachers that show them how to position all of their students as active doers of science so all students have opportunities to build deeper, core science knowledge.  相似文献

In this study, a multiple-choice test entitled the Science Process Assessment was developed to measure the science process skills of students in grade four. Based on the Recommended Science Competency Continuum for Grades K to 6 for Pennsylvania Schools, this instrument measured the skills of (1) observing, (2) classifying, (3) inferring, (4) predicting, (5) measuring, (6) communicating, (7) using space/time relations, (8) defining operationally, (9) formulating hypotheses, (10) experimenting, (11) recognizing variables, (12) interpreting data, and (13) formulating models. To prepare the instrument, classroom teachers and science educators were invited to participate in two science education workshops designed to develop an item bank of test questions applicable to measuring process skill learning. Participants formed “writing teams” and generated 65 test items representing the 13 process skills. After a comprehensive group critique of each item, 61 items were identified for inclusion into the Science Process Assessment item bank. To establish content validity, the item bank was submitted to a select panel of science educators for the purpose of judging item acceptability. This analysis yielded 55 acceptable test items and produced the Science Process Assessment, Pilot 1. Pilot 1 was administered to 184 fourth-grade students. Students were given a copy of the test booklet; teachers read each test aloud to the students. Upon completion of this first administration, data from the item analysis yielded a reliability coefficient of 0.73. Subsequently, 40 test items were identified for the Science Process Assessment, Pilot 2. Using the test-retest method, the Science Process Assessment, Pilot 2 (Test 1 and Test 2) was administered to 113 fourth-grade students. Reliability coefficients of 0.80 and 0.82, respectively, were ascertained. The correlation between Test 1 and Test 2 was 0.77. The results of this study indicate that (1) the Science Process Assessment, Pilot 2, is a valid and reliable instrument applicable to measuring the science process skills of students in grade four, (2) using educational workshops as a means of developing item banks of test questions is viable and productive in the test development process, and (3) involving classroom teachers and science educators in the test development process is educationally efficient and effective.  相似文献

ABSTRACT

Students at open-enrollment institutions enter college with a wide range of academic preparedness and are often required to take developmental classes to increase their academic skills to be successful in higher education. Further, few students possess self-regulated learning skills to aid in their learning. Researchers posited that academically at-risk students benefit from gains in self-regulated learning skills when a modeling and scaffolding approach is used to implement self-regulated learning tools. Self-regulated skills coupled with an active learning environment like the flipped classroom provide positive synergistic effects for academically at-risk students. This study compared several iterations of the flipped classroom in a general chemistry class at an open-enrollment college where high school class rank and mathematics placement level varied significantly. The results of the multiple regression analysis indicated that mathematics level and class rank were significant when predicting overall course grade regardless of the learning environment. The results of a paired-samples t test did not reveal a significant difference upon addition of note-taking and exam wrappers in a flipped classroom learning environment. However, students graduating high school in the top third, middle third, and bottom third of their graduating class increased their overall course grades in a flipped classroom using self-regulated tools by 7%, 3%, and 6%, respectively. To enhance the quantitative results, the author provides student comments on note-taking and the use of exam wrappers.  相似文献

Science education research has recommended cooperative inquiry based science in the primary science context for more than two decades but after more than 20 years, student achievement in science has not substantially improved. This study, through direct observation and analysis, investigated content-related student interactions in an authentic inquiry based primary science class setting. Thirty-one upper primary students were videotaped working in cooperative inquiry based science activities. Cooperative talk and negotiation of the science content was analysed to identify any high-level group interactions. The data show that while all groups have incidences of high-level content-related group interactions, the frequency and duration of these interactions were limited. No specific pattern of preceding events was identified and no episodes of high-level content-related group interactions were immediately preceded by the teacher’s interactions with the groups. This in situ study demonstrated that even without any kind of scaffolding, specific skills in knowing how to implement cooperative inquiry based science, high-level content-related group interactions did occur very briefly. Support for teachers to develop their knowledge and skills in facilitating cooperative inquiry based science learning is warranted to ensure that high-level content-related group interactions and the associated conceptual learning are not left to chance in science classrooms.  相似文献

Psychological science has identified positive classroom management and climate building strategies as a key element in developing and maintaining effective learning environments. In this article, we review the literature that has identified effective strategies that build classroom climates to maximize student learning and minimize disruption. In general, these strategies indicate a shift away from reactive and punitive approaches towards an emphasis on instructional and preventive approaches, including setting clear expectations, appropriate curriculum to increase student engagement, positive acknowledgment, and building relationships between students and teachers. Emerging research has also begun to identify features of culturally responsive classroom management that can engage and build relationships for a diverse student population.  相似文献

This study involved 458 ninth-grade students from two different Arab middle schools in Israel. Half of the students learned science using project-based learning strategies and the other half learned using traditional methods (non-project-based). The classes were heterogeneous regarding their achievements in the sciences. The adapted questionnaire contained 38 statements concerning students’ perceptions of the science classroom climate. The results of the study revealed that students who learned sciences by project-based teaching strategies perceived their classroom learning climate as significantly more Satisfying and Enjoyable, with greater Teacher Supportiveness, and the Teacher–Student Relationships as significantly more positive. The differences between the experimental (project-based learning strategies) and control (non-project) groups regarding their perceptions of the science classroom learning climate could be explained by differences between the two science teaching and learning strategies.  相似文献

Study provides qualitative analysis of data that answers the following research question: how college science faculty teach science and NOS and incorporate aspects of NOS and the history of science into their undergraduate courses? Study concentrates on four cases and more specifically on three introductory science classes and on four instructors who taught those courses. These instructors were chosen as case studies to explore in greater detail what occurs inside introductory science courses in one particular higher institution in the Northeastern United States. Participants’ teaching styles are presented through a combined and detailed presentation of interview data and classroom observations supported with examples from their classroom activities. Constant comparative approach was used in the process of organizing and analyzing data. Findings revealed that participants preferred to use the traditional teacher-centered lecturing as their teaching style and whose main concern was to cover more content, develop the problem solving skills of their students, and who wanted to teach the fundamental principles of their subjects without paying special importance to the NOS aspects. The study also revealed that other variables of teaching science, such as large class size, lack of management and organizational skills, teaching experience, and instructors’ concerns for students’ abilities and motivation are more important for these scientists then teaching for understanding of NOS.  相似文献

Science consists of a body of knowledge and a set of processes by which the knowledge is produced. Although these have traditionally been treated separately in science instruction, there has been a shift to an integration of knowledge and processes, or set of practices, in how science should be taught and assessed. We explore whether a general overall mastery of the processes drives learning in new science content areas and if this overall mastery can be improved through engaged science learning. Through a review of literature, the paper conceptualizes this general process mastery as scientific sensemaking, defines the sub-dimensions, and presents a new measure of the construct centered in scenarios of general interest to young adolescents. Using a dataset involving over 2500 6th and 8th grade students, the paper shows that scientific sensemaking scores can predict content learning gains and that this relationship is consistent across student characteristics, content of instruction, and classroom environment. Further, students who are behaviorally and cognitively engaged during science classroom activities show greater growth in scientific sensemaking, showing a reciprocal relationship between sensemaking ability and effective science instruction. Findings from this work support early instruction on sensemaking activities to better position students to learn new scientific content.  相似文献

Science textbooks are dominant influences behind most secondary science instruction but little is known about teachers' approach to science reading. The purpose of this naturalistic study was to develop and validate a Science and Reading Questionnaire to assess secondary science teachers' attitudes toward science reading and their beliefs or informed opinions about science reading. A survey of 428 British Columbia secondary science teachers was conducted and 215 science teachers responded. Results on a 12-item Likert attitude scale indicated that teachers place high value on reading as an important strategy to promote learning in science and that they generally accept responsibility for teaching content reading skills to science students. Results on a 13-item Likert belief scale indicated that science teachers generally reject the text-driven model of reading, but they usually do not have well-formulated alternative models to guide their teaching practices. Teachers have intuitive beliefs about science reading that partially agree with many research findings, but their beliefs are fragmented and particularly sketchy in regard to the cognitive and metacognitive skills required by readers to learn from science texts. The findings for attitude, belief, and total scales were substantiated by further questions in the Science and Reading Questionnaire regarding classroom practice and by individual interviews and classroom observations of a 15-teacher subsample of the questionnaire respondents.  相似文献
