High school laboratory work in Western Australia: Openness to inquiry

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.     

Analysis of verbal interactions during an extended,open‐inquiry general chemistry laboratory investigation

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.

Traversing the Divide Between High School Science Students and Sophisticated Nature of Science Understandings: A Multi-pronged Approach

This study investigated the effects of a multi-pronged approach of increasing the nature of science (NOS) understandings of high school science students. The participants consist of 63 high school students: 31 in the intervention group and 32 in the control group. Explicit/reflective NOS instruction was imbedded within authentic inquiry experiences and supported by online discussions. The students in the intervention group were prompted to engage in various discussions focusing on essential tenets of NOS in an online environment that assured student confidentiality. NOS views were assessed through multiple data sources including pre- and post-intervention questionnaires as well as students’ responses to online discussion prompts. Results show that the instructional intervention used in this study which combined explicit/reflective NOS instruction with intense inquiry exposure along with ample reflective opportunities in an anonymous online discussion format led to positive learning gains in participants’ understanding the NOS aspects assessed. Implications for enhancing data collection with high school students and for promising professional development opportunities for science educators are discussed.     

Assessment of the Learning Environment of Inquiry-Type Laboratories in High School Chemistry

An inquiry-type laboratory has been implemented into the chemistry curriculum in high schools in Israel. In this study, we investigated the idea that generally the science laboratory provides a unique learning environment that differs from the learning environment that exists in classrooms in which other instructional techniques are used. Moreover, the inquiry laboratory provides students with a learning situation in which they are involved in activities that might influence some of the variables that are influencing the learning environment of such laboratories. In this study, the Science Laboratory Environment Inventory (SLEI) was used to assess the students' perceptions of their chemistry laboratory learning environment. Statistical comparison of two groups (control and inquiry) revealed significant differences between the groups regarding their actual perceptions. Moreover, it was found that the differences between the actual and preferred laboratory learning environment were significantly smaller for the inquiry group than for the control group.

Teaching About Theory-Laden Observation to Secondary Students Through Manipulated Lab Inquiry Experience

This study seeks to develop and evaluate a modified lab inquiry approach to teaching about nature of science (NOS) to secondary students. Different from the extended, open-ended inquiry, this approach makes use of shorter lab inquiry activities in which one or several specific NOS aspects are manipulated deliberately so that students are compelled to experience and then reflect on these NOS aspects. In this study, to let students experience theory-laden observation, they were provided with different “theories” in order to bias their observations in the lab inquiry. Then, in the post-lab discussion, the teacher guided students to reflect on their own experience and explicitly taught about theory-ladenness. This study employs a quasi-experimental pretest–posttest design using the historical approach as the control group. The results show that the manipulated lab inquiry approach was much more effective than the historical approach in fostering students’ theory-laden views, and it was even more effective when the two approaches were combined. Besides, the study also sought to examine the practical epistemological beliefs of students concerning theory-ladenness, but limited evidence could be found.     

Learning Environment, Attitudes and Achievement among Middle-school Science Students Using Inquiry-based Laboratory Activities

This study compared inquiry and non-inquiry laboratory teaching in terms of students’ perceptions of the classroom learning environment, attitudes toward science, and achievement among middle-school physical science students. Learning environment and attitude scales were found to be valid and related to each other for a sample of 1,434 students in 71 classes. For a subsample of 165 students in 8 classes, inquiry instruction promoted more student cohesiveness than non-inquiry instruction (effect size of one-third of a standard deviation), and inquiry-based laboratory activities were found to be differentially effective for male and female students.     

Grade 5 Students’ Online Argumentation about Their In-Class Inquiry Investigations

This study examined the extent to which fifth-grade students participate in online argumentation and the argument patterns they produced about the inquiry-based investigations completed using the Science Writing Heuristic approach in their science classes. One hundred twenty-nine students from five classes of two teachers in a Midwestern public school completed two inquiry-based investigation units, one per semester, followed by asynchronous online discussions using the Moodle forum. Among the 129 students, 107 students produced 739 notes in the plant investigation online discussion and 111 students produced 686 notes in the human health investigation online discussion. Results indicate that students were actively engaged in the online discussions about inquiry investigations with comments being focused on providing more evidence and backing for claims and negotiating evidence in both investigations. The students also engaged in challenging and querying the test procedures and reference sources as the basis for evidence. Implications are discussed for science teaching and learning and further study on argument-based inquiry in online environments.     

The effect of reflective discussions following inquiry‐based laboratory activities on students' views of nature of science

This research investigated the effect of reflective discussions following inquiry‐based laboratory activities on students' views of the tentative, empirical, subjective, and social aspects of nature of science (NOS). Thirty‐eight grade six students from a Lebanese school participated in the study. The study used a pretest–posttest control‐group design and focused on collecting mainly qualitative data. During each laboratory session, students worked in groups of two. Later, experimental group students answered open‐ended questions about NOS then engaged in reflective discussions about NOS. Control group students answered open‐ended questions about the content of the laboratory activities then participated in discussions of results of these activities. Data sources included an open‐ended questionnaire used as pre‐ and posttest, answers to the open‐ended questions that experimental group students answered individually during every session, transcribed videotapes of the reflective discussions of the experimental group, and semi‐structured interviews. Results indicated that explicit and reflective discussions following inquiry‐based laboratory activities enhanced students' views of the target NOS aspects more than implicit inquiry‐based instruction. Moreover, implicit inquiry‐based instruction did not substantially enhance the students' target NOS views. This study also identified five major challenges that students faced in their attempts to change their NOS views. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 1229–1252, 2010     

Laboratory apprenticeship through a student research project

There has been a long tradition of laboratory activities associated with science instruction. Despite constructivists' claims advocating open-ended inquiry and mentoring, little is known about what students are thinking when engaged in laboratory activities. Laboratory learning as a process of cognitive apprenticeship has been proposed as a metaphor to guide teacher practice and student learning. The viability of cognitive apprenticeship for learning science in school is discussed in relation to findings from an investigation of a research project involving high school students working in a university chemical engineering laboratory under the mentorship of a university-based scientist. Data from a variety of techniques were analyzed in an interpretive style. We found that the students were empowered to seek empirically viable knowledge claims as they became independent researchers. However, we argue that caution needs to be exercised before advocating open-ended inquiry as a general model for laboratory learning without additional studies in different contexts. © 1996 John Wiley & Sons, Inc.     

The use of wikis in a science inquiry-based project in a primary school

This study explored the use of wikis in a science inquiry-based project conducted with Primary 6 students (aged 11–12). It used an online wiki-based platform called PBworks and addressed the following research questions: (1) What are students’ attitudes toward learning with wikis? (2) What are students’ interactions in online group collaboration with wikis? (3) What have students learned with wikis in a science inquiry-based project in a primary school context? Analyses of the quantitative and qualitative data showed that with respect to the first research question, the students held positive attitudes toward the platform at the end of the study. With respect to the second research question, the students actively engaged in various forms of learning-related interactions using the platform that extended to more meaningful offline interactions. With respect to the third research question, the students developed Internet search skills, collaborative problem solving competencies, and critical inquiry abilities. It is concluded that a well-planned wiki-based learning experience, framed within an inquiry project-based approach facilitated by students’ online collaborative knowledge construction, is conducive to the learning and teaching of science inquiry-based projects in primary school.     

The Translation of Curriculum into Instruction

The justification advanced by teachers and curriculum developers for investing so much time, energy and resources in laboratory work in school science courses almost invariably includes the claim that it provides students with insight into, and experience and practice of, the methods of science. This paper traces the changing nature of laboratory work from the 1960s to the present, from discovery learning to process‐led science to contemporary constructivist approaches, and argues that each of these styles of laboratory work has seriously misrepresented and distorted the nature of scientific inquiry. Some suggestions are made for the re‐orientation of laboratory work to ensure that it projects an image of science that more faithfully reflects actual scientific practice.     

The effects of computer-supported self-regulation in science inquiry on learning outcomes,learning processes,and self-efficacy

Recently, researchers have demonstrated the benefits of technology-enhanced science inquiry activities. To improve students’ self-regulation and assist them in controlling their own learning pace through inquiry activities, in this study, a self-regulated science inquiry approach was developed to assist them in organizing information from their real-world exploration. A quasi-experimental design was conducted in an elementary school natural science course to evaluate the students’ performance using the proposed learning approach. One class assigned as the treatment group learned with the self-regulated science inquiry approach, while the other class assigned as the control group learned with the conventional science inquiry approach. The students’ learning achievement, tendency of information help seeking, tendency of self-regulation, and self-efficacy were evaluated. The results of the study revealed that the self-regulated science inquiry approach improved the students’ learning achievement, especially for those students with higher self-regulation. In addition, the students who conducted inquiry with the self-regulated learning strategy increased their tendency of information help seeking, self-efficacy, and several aspects of self-regulation, including time management, help seeking, and self-evaluation. Accordingly, this study demonstrated the effectiveness of the self-regulated learning strategy, an approach with high learner control, in terms of improving students’ learning achievement and their self-regulation.     

The Effects of Prior-knowledge and Online Learning Approaches on Students’ Inquiry and Argumentation Abilities

This study investigated the effects of students’ prior science knowledge and online learning approaches (social and individual) on their learning with regard to three topics: science concepts, inquiry, and argumentation. Two science teachers and 118 students from 4 eighth-grade science classes were invited to participate in this research. Students in each class were divided into three groups according to their level of prior science knowledge; they then took either our social- or individual-based online science learning program. The results show that students in the social online argumentation group performed better in argumentation and online argumentation learning. Qualitative analysis indicated that the students’ social interactions benefited the co-construction of sound arguments and the accurate understanding of science concepts. In constructing arguments, students in the individual online argumentation group were limited to knowledge recall and self-reflection. High prior-knowledge students significantly outperformed low prior-knowledge students in all three aspects of science learning. However, the difference in inquiry and argumentation performance between low and high prior-knowledge students decreased with the progression of online learning topics.     

Learning from inquiry‐based laboratories in nonmajor biology: An interpretive study of the relationships among inquiry experience,epistemologies, and conceptual growth

The use of inquiry‐based laboratory in college science classes is on the rise. This study investigated how five nonmajor biology students learned from an inquiry‐based laboratory experience. Using interpretive data analysis, the five students' conceptual ecologies, learning beliefs, and science epistemologies were explored. Findings indicated that students with constructivist learning beliefs tended to add more meaningful conceptual understandings during inquiry labs than students with positivist learning beliefs. All students improved their understanding of experiment in biology. Implications for the teaching of biology labs are discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 986–1024, 2003
