A practical test instrument was developed to assess students' attainment of skills associated with problem analysis and planning
experiments, collecting information, organising and interpreting information, and concluding. Students verbalised their thoughts
as they worked on the task and their performance was videotaped for analysis. Data collected from Year 7, 10 and 12 science
students illustrate the development of investigation skills and reveal important areas of student weakness.

Summer science programs held in university research facilities provide ideal opportunities for pre-college students to master new skills and renew, refresh, and enrich their interest in science. These types of programs have a positive impact on a student's understanding of the nature of science and scientific inquiry and can open a youngster's eyes to the many possible career opportunities in science. This paper describes a study of high school students enrolled in the Summer Science Academy program at the University of Rochester that investigates the program's impact on students' knowledge of laboratory skills, as well as the impact on student interest in pursuing a career in science. Students' exposure to advanced laboratory techniques and their interaction with professional scientists provided them with a very positive hands-on experience. Students who attended the program felt more confident in their ability to use sophisticated laboratory skills and that the Summer Science Academy program provided a positive influence on their performance in advanced science courses, as well as their desire to pursue a career in science. 相似文献

Two parallel versions of a Test of Science Investigation Skills were developed to assess students' application of science
investigation skills in biology and physics contexts. Repeated pilot testing and critical appraisal were used to ensure the
validity of the tests and their equivalence. Both versions of the test were administered to 112 Year 10 science students.
The results indicated a satisfactory level of test reliability, the test set in a physics context proved to be significantly
more difficult than the test set in a biology context, and mean scores for male and female students were not significantly
different.

The purpose of this study was to investigate and compare the impact of Internet Virtual Physics Laboratory (IVPL) instruction
with traditional laboratory instruction in physics academic achievement, performance of science process skills, and computer
attitudes of tenth grade students. One-hundred and fifty students from four classes at one private senior high school in Taoyuan
Country, Taiwan, R.O.C. were sampled. All four classes contained 75 students who were equally divided into an experimental
group and a control group. The pre-test results indicated that the students’ entry-level physics academic achievement, science
process skills, and computer attitudes were equal for both groups. On the post-test, the experimental group achieved significantly
higher mean scores in physics academic achievement and science process skills. There was no significant difference in computer
attitudes between the groups. We concluded that the IVPL had potential to help tenth graders improve their physics academic
achievement and science process skills. 相似文献

"Do I need to know this for the exam?" Using popular media, inquiry-based laboratories, and a community of scientific practice to motivate students to learn developmental biology 
下载免费PDF全文
下载免费PDF全文 One of the greatest challenges instructors face is getting students to connect with the subject in a manner that encourages them to learn. In this essay, we describe the redesign of our Developmental Biology course to foster a deeper connection between students and the field of developmental biology. In our approach, we created a community of scientific practice focused on the investigation of environmental impacts on embryonic development and informed by popular and scientific media, the students' own questions, and the instructor. Our goals were to engage students in meaningful ways with the material, to develop students' science process skills, and to enhance students' understanding of broad principles of developmental biology. Though significant challenges arose during implementation, assessments indicate using this approach to teach undergraduate developmental biology was successful. 相似文献

Research Findings: The purpose of this study was to investigate the factorial structure of kindergarten children's mathematics and science process skills and the impact of children's competencies in process skills on their performance on mathematics and science achievement tests in 3rd grade. A subset of the Early Childhood Longitudinal Study–Kindergarten cohort data set (n = 8,731) was analyzed using multilevel structural equation modeling. Results demonstrated that science and mathematics process skills were highly related at the construct level but not at the indicator level, as was anticipated. Kindergarten children's competency in mathematics process skills was a strong predictor of their performance on science and mathematics achievement tests in the 3rd grade. However, children's competency in science process skills was only a significant predictor of their performance on a science achievement test in the 3rd grade. Moreover, socioeconomic status and gender were statistically significant predictors of process skills and performance on achievement tests. Practice or Policy: The findings of the present study suggest that the development of children's science and mathematics process skills should be supported utilizing integrated inquiry-based science and mathematics activities to help children recognize the connection between mathematics and science and to contribute to their science and mathematics achievement in later grades. 相似文献

Many school students experience difficulty in conducting science investigations (Hackling & Garnett, 1991; Murphy, 1988).
Students in Western Australia have poorly developed skills of problem analysis, planning and carrying out controlled experiments,
basing conclusions only on obtained data, and recognising limitations in the methodology of their investigations. This paper
compares the work of 10 expert scientists and 10 Year 12 science students as they conducted a laboratory based investigation.
The results provide insights into expertise in science investigation skills.

There is an expectation that new science teachers will be able to effectively use a range of information communication technology (ICT) related resources inthe science classroom in order to enhance student learning. All school systems in Australia are in the process of providing teachers with ICT professional development and infrastructure. This paper outlines a range of initiatives designed to integrate ICT in a compulsory science education unit for students enrolled in a Graduate Diploma in Secondary Education. An action research model based on constructivist principles was used to evaluate the effectiveness of modelling, open-ended co-operative group activities and authentic assessment in enabling students to enhance their ICT skills, knowledge and pedagogical content knowledge in a science education context. Multiple sources of data were generated including a pre and post unit questionnaire that was analysed using Rasch modelling. The questionnaire determined students' perceptions of their preparedness to teach using ICT. The findings of this research suggest that some skills warranted greater attention in the unit, but students' pedagogical knowledge and knowledge and critique of ICT resources were enhanced over the duration of the unit. 相似文献

This paper reports on a study of children learning science through investigations. Because many skill-type performances depend upon knowing and understanding the relevant content, this paper addresses both the children's understanding of scientific ideas and their performance of the science process skills. Twenty-four written records of investigations conducted by Hong Kong primary school children were studied to explore children's cognitive processes in scientific investigations. The paper concludes with a model that provides useful information about aspects of children's cognitive understanding and the practical processes that are necessary for scientific investigation. 相似文献

The purpose of this study is to investigate the effects of the cooperative learning approach based on conceptual change conditions
over traditional instruction on 10th grade students' conceptual understanding and achievement of computational problems related
to chemical equilibrium concepts. The subjects of this study consisted of 87 tenth grade students from two intact classes
of a Chemistry Course instructed by the same teacher. One of the classes was randomly assigned as the experimental group,
which was instructed with cooperative learning approach based on conceptual change conditions and the other class was assigned
as the control group, which was instructed with traditional instruction. Chemical Equilibrium Concept Test (CECT) was administered
to the experimental and the control groups as pre- and post-tests to measure the students' conceptual understanding, and Chemical
Equilibrium Achievement Test (CEAT) was administered to the experimental and the control groups as a post-test to measure
the students' achievements related to computational problems. Science Process Skills Test was used at the beginning of the
study to determine the students' science process skills. Multivariate Analysis of Covariate (MANCOVA) was used to analyze
the data. The results showed that students in the experimental group had better conceptual understanding, and achievement
of computational problems related to the chemical equilibrium concepts. Furthermore, students' science process skills were
accounted for a significant portion of variations in conceptual understanding and achievements related to the computational
problems. 相似文献

This study explores effects of participation by second‐semester college general chemistry students in an extended, open‐inquiry laboratory investigation. Verbal interactions among a student lab team and with their instructor over three open‐inquiry laboratory sessions and two non‐inquiry sessions were recorded, transcribed, and analyzed. Coding categories were developed using the constant comparison method. Findings indicate that, during open‐inquiry activities, the student team interacted less often, sought less instructor guidance, and talked less about chemistry concepts than during their non‐inquiry activities. Evidence suggests that the students employed science process skills and engaged in higher‐order thinking during both types of laboratory activities. Implications for including open‐inquiry experiences in general chemistry laboratory programs on student understanding of science as inquiry are discussed. © 2007 Wiley Periodicals, Inc.

This experimental study compared an interactive computer/videodisc learning approach to the conventional laboratory approach for learning biology concepts and science process skills. Students at a large midwestern university were randomly assigned to instruction on respiration and biogeography by interactive videodisc or a traditional laboratory investigation teaching the same concepts. The videodisc delivery system consisted of a TRS-80 Model III microcomputer interfaced to a Pioneer laser disc player and a color TV monitor. Results show no statistically significant differences between the two approaches for student grades on laboratory quizzes, laboratory reports, and the laboratory final exam. However, the interactive videodisc group required approximately one-half the classroom time used by the conventional laboratory group. The two approaches appear equivalent when evaluated by traditional learning outcomes, but the interactive videodisc strategy was significantly more time efficient than a traditional laboratory approach. 相似文献

The purpose of this study is to investigate the effects of computer-assisted videodisc-based anchored instruction on attitudes toward mathematics and instruction as well as problem-solving skills among Taiwanese elementary students. Results from a t-test indicate a significant main effect on student attitudes toward mathematics. Results from a two-way Repeated Measures ANOVA show that students' problem-solving skills improve significantly with anchored instruction. Results also indicate that all the students benefit from the effects of anchored instruction on their problem-solving performance regardless of their mathematics and science abilities. The findings suggest that video-based anchored instruction provide a more motivating environment that enhanced students' problem-solving skills. This study is significant because it establishes an example of video-based anchored instruction for Taiwanese students and also provides empirical evidence of its effects on affective and cognitive responses among fifth graders in learning mathematics. This study is helpful to educators who want to help students learn to think and learn throughout technology. 相似文献

Instructional strategies and curriculum sequences aimed at teaching process skills have received considerable attention in science education. On the other hand, the teaching of domain-independent, context-free skills has been subject to criticism on the ground that important aspects of cognitive activities are functions of meaningful contexts. The intent of this study was to examine the development of integrated process skills in the context of open-inquiry laboratory sessions. The data-collection approach was qualitative and included videotapes of laboratory sessions, laboratory reports of students, and the reflective journals kept by the two teachers involved in the study. Forty-eight students from the Grade 11 introductory physics course, 29 students from the Grade 12 physics course, and 60 students from the Grade 8 general science course from an all-boys private school participated in the study. An interpretive research methodology was adopted for construction of meaning from the data. Students worked in collaborative groups during all of the open-inquiry laboratory sessions. Findings from the study indicate that students develop higher-order process skills through nontraditional laboratory experiences that provided the students with freedom to perform experiments of personal relevance in authentic contexts. Students learned to (a) identify and define pertinent variables, (b) interpret, transform, and analyze data, (c) plan and design an experiment, and (d) formulate hypotheses. Findings of this study suggest that process skills need not be taught separately. Integrated process skills develop gradually and reach a high level of sophistication when experiments are performed in meaningful context. 相似文献

The development of reasoning skills, higher-level thinking skills, and science process skills are some of the benefits students can realize by participating in inquiry in the science laboratory. We used student responses to the Alternative Assessment of Science Process Skills (AASPS) developed by the Missouri Department of Education and the Department of Educational Assessment to develop the Science Process Skills Inventory (SPSI). The SPSI was then used to analyze student efforts at writing experimental designs. Our goal was to gain insight into factors that may be related to students successfully designing experiments. The instrument guides teachers and researchers in assessing seven main components of experimental designs. Each component consists of elements unique to the specific laboratory exercise. Subsequent to its development, the instrument was used to score 364 student responses to the “design an experiment” portion of an alternative assessment instrument for science process skills. Results indicate that explicit, incremental development of the science process skills of formulating hypotheses and identifying variables, together with model examples, may be a means to facilitate student success in designing science experiments. Implications for the classroom and for research are discussed. © 1996 John Wiley & Sons, Inc. 相似文献

Laboratory work has always been the most distinctive feature of secondary science teaching and learning. With the increasing
emphasis on student centred learning and the importance of developing investigation and problem-solving skills there is value
in reflecting on the type of laboratory work that is carried out in the science curriculum. The purpose of this study was
to determine the nature of the laboratory work undertaken by lower secondary science students, and in particular, to determine
the openness to inquiry of these activities. The study also examined the factors that influence teachers in determining the
type of student investigations that occur in the science laboratory. Data from a survey of Perth lower secondary science teachers
reveal low levels of inquiry and interesting insights into teacher's perceptions about the benefits of open inquiry for students
and the difficulities for teachers. The difficulties identified by teachers represent barriers to change that must be addressed
if more open inquiry laboratory work is to be implemented in schools. 相似文献

This paper reports on an investigation into Hong Kong students' comprehension of English non-technical words used in science.
The investigation was conducted in a context in which English, a foreign language to students, is the medium of instruction,
in that textbooks and examinations are all in English but the classroom language used is mainly Chinese, with frequent Chinese-English
code-switching. A total of 4644 Secondary 4, 5 and 6 students participated in the study. Many students did not correctly comprehend
a large proportion of the words, confused them with words that were graphologically or phonetically similar, and even took
them for their antonyms. Such poor performance raises doubts as to whether the majority of Hong Kong students have attained
a ‘threshold level’ of competence in English to benefit from learning science in English.

As schools are becoming increasingly diverse in their scope and clientele, any examination of the interaction of culturally
sensitive factors of students' learning environments with learning science assumes critical importance. The purpose of this
exploratory study was to develop an instrument to assess learning environment factors that are culturally sensitive, to provide
initial validation information on the instrument and to examine associations between students' perceptions of their learning
environments and their attitudes towards science and achievement of enquiry skills. A measure of these factors of science
student's learning environment, namely the Cultural Learning Environment Questionnaire (CLEQ), was developed from past learning
environment instruments and influenced by Hofstede's four dimensions of culture (Power Distance, Uncertainty Avoidance, Individualism,
and Masculinity/Femininity). The reliability and discriminant validity for each scale were obtained and associations between
learning environment, attitude to science and enquiry skills achievement were found. 相似文献

The study examined the differences in cognitive styles between two comparable groups of students at the Grade 9 (Secondary 3) level, namely the LSS (Lower Secondary Science) group who had been exposed to the practical-based, inquiry-oriented type of science and the non-LSS group of students who had studied the more traditional type of science in the “old” science curriculum. Their differences in science achievement are measured by the common IEA Science Paper-Pencil, Multiple Choice Criterion Test and also, by the Science Process or Practical Test (which measured three levels of process skills, such as the observation/manipulation, reasoning and investigation skills). Variance in science achievement thus measured is examined against the 4 cognitive preference styles of the students, (measured by the Combined Cognitive Preference Inventory) namely the “recall”, “principles”, “applications” and “questioning” modes of thinking. The findings indicated that (a) the attainment of the science process or practical skills was characterised by the type of science curriculum (LSS or non-LSS) and it was significantly associated with the achievement level of students, (b) the cognitive preference pattern covaried according to the students' level of science achievement and the type of curriculum and (c) the weak but significant relationship between performance in the science practical skills and the students' modes of cognitive style have important implications for teachers who are concerned about the intended effects of changes in the science curriculum on the consequent learning behaviour or cognitive outcome of their students. 相似文献
