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.     

Cognitive regulation,not behavior regulation,predicts learning

Although inquiry learning has increasingly been a topic of empirical research, there has been little investigation of individual differences in this regard. What makes some students more effective inquiry learners than others? We examined two kinds of self-regulation – cognitive regulation and behavior regulation – as possible predictors of individual differences in middle-school students’ inquiry learning performance. Across two studies, one involving middle-class students (n = 135) and one involving students from a lower socioeconomic status underachieving population (n = 21), results were consistent. Cognitive regulation, but not behavior regulation, was associated with more successful inquiry learning. We discuss implications for the role of regulatory processes in inquiry learning and, more broadly, for education.     

Networking for Leadership,Inquiry, and Systemic Thinking: A New Approach to Inquiry-Based Learning

Recent changes in science education standards have mandated a prominent place for inquiry learning in science curricula. However, change from traditional teaching methods to a more inquiry-centered approach is difficult to enact. While research to date demonstrates a number of successful inquiry implementations, it also reveals a slow rate of change along with possible reasons for difficulty in adopting inquiry instructional methods. Further, inquiry reforms have failed in the past. The Networking for Leadership, Inquiry, and Systemic Thinking (NLIST) initiative, sponsored by the Council of State Science Supervisors and NASA, proposes to facilitate inquiry through systemic reform designed to avoid the mistakes of the past and incorporate new knowledge about teaching and learning. Systemic elements targeted for change include a standard conceptualization of science as inquiry, instructional materials, professional development, administrative support and leadership, facilities, community involvement, and technology infrastructure. To date, the initiative has created a detailed definition of inquiry learning and a rubric for evaluating instructional materials against this definition. This paper presents the theoretical and empirical foundations for the NLIST initiative, describes its progress, and outlines future goals.     

Collaboration modality, cognitive load, and science inquiry learning in virtual inquiry environments

Educational multi-user virtual environments (MUVEs) have been shown to be effective platforms for situated science inquiry curricula. While researchers find MUVEs to be supportive of collaborative scientific inquiry processes, the complex mix of multi-modal messages present in MUVEs can lead to cognitive overload, with learners unable to effectively process the rich information encountered in virtual space. In this study, we investigated the effect of communication modality on cognitive load and science inquiry learning in students completing a science inquiry curriculum in an educational MUVE. Seventy-eight undergraduate education majors from a large southwestern university participated in this control-treatment study. Significant positive results were found for reducing cognitive load for participants communicating through voice-based chat, although this reduction was not found to influence learning outcomes. We conclude that use of voice-based communication can successfully reduce cognitive load in MUVE-based inquiry curricula.     

PLANNING, ENACTMENT, AND REFLECTION IN INQUIRY-BASED LEARNING: VALIDATING THE MCGILL STRATEGIC DEMANDS OF INQUIRY QUESTIONNAIRE

Tools are needed to track the elements of students’ successful engagement in inquiry. The McGill Strategic Demands of Inquiry Questionnaire (MSDIQ) is a 79-item, criterion-referenced, learner-focused questionnaire anchored in Sch?n’s model and related models of self-regulated learning. The MSDIQ addresses three phases of inquiry engagement—planning, enactment, reflection—perceived as important by teachers, parents, and students before or after inquiry participation. Internal consistency and validity evidence was obtained from 205 university students with different inquiry backgrounds: teacher education years 1 and 4, continuing teacher education, and honors psychology. Separate confirmatory factor analyses of planning, enactment, and reflection generated 14 intercorrelated factors congruent with definitions of inquiry instruction and supported the hypothesized structure underlying the MSDIQ as a reliable and valid instrument for measuring inquiry engagement and valuing its building blocks.     

Examining Arguments Generated by Year 5, 7, and 10 Students in Science Classrooms

A critical component of science is the role of inquiry and argument in moving scientific knowledge forward. However, while students are expected to engage in inquiry activities in science classrooms, there is not always a similar emphasis on the role of argument within the inquiry activities. Building from previous studies on the Science Writing Heuristic (SWH), we were keen to find out if the writing structure used in the SWH approach helped students in Year 5, 7, and 10 to create well constructed arguments. We were also interested in examining which argument components were important for the quality of arguments generated by these students. Two hundred and ninety six writing samples were scored using an analysis framework to evaluate the quality of arguments. Step-wise multiple regression analyses were conducted to determine important argument components. The results of this study suggest that the SWH approach is useful in assisting students to develop reasonable arguments. The critical element determining the quality of the arguments is the relationship between the student’s written claims and his or her evidence.     

Establishing the Criterion-related,Construct, and Content Validities of a Simulation-based Assessment of Inquiry Abilities

The emphasis on scientific inquiry has increased the importance in developing the fundamental abilities to conduct scientific investigations and urged a need for valid assessments of students' inquiry abilities. We took advantage of the advanced technology to develop a simulation-based assessment of inquiry abilities (SAIA) that allowed students to generate scientific explanations and demonstrate their experimental abilities. This paper describes the validation of the assessment. Data were collected from 48 12th-grade students at a local high school who were categorized into three groups based on their program majors. Both quantitative and qualitative approaches were utilized to validate SAIA. The quantitative results showed that SAIA was aligned with a validated reasoning-skill test (criterion-related validity), discriminated variance among different groups (construct validity), and was highly suitable for examining inquiry abilities (content validity). Additionally, we utilized the think-aloud technique in order to identify the performances exhibited by students while they accomplished the SAIA tasks. The protocol analysis indicated that in general, students demonstrated the expected abilities in SAIA and that their SAIA scores accurately reflected their performance levels of inquiry abilities. The results suggested that SAIA was a valid assessment for evaluating the inquiry abilities of high school students. This study also provided systemic strategies for validating simulation-based assessments.     

Redefining our Roles as Teachers,Learners, and Leaders through Continuous Cycles of Practitioner Inquiry

ABSTRACT

Practitioner inquiry is an alternative form of professional learning that can result in significant changes in teacher practice and student learning. We share our evolution as teacher learners within our classrooms and teacher leaders within our school as we progressed through 10 years of continuous cycles of practitioner inquiry. Beginning as novice inquirers examining classroom-specific problems of practice and evolving into experienced facilitators of practitioner inquiry, we have expanded our roles as teacher leaders among our colleagues as we collaboratively lead a secondary change initiative in equitable assessment practices, a direct result of continuously making our learning through engagement in practitioner inquiry public.     

Epistemology, Science, and Moral Practice

Two features of discussions on epistemology in the social sciences and education are examined. One is the depiction of science by its critics, the other is the separation of scientific inquiry and ethics. I describe science as very human and very fallible, but also very successful. Contrary to critics, science is not a search for eternal truth or an ultimate reality, rather it is tentative, self-corrective, and growing. Other anti-science arguments are also explored.The separation of ethics from the methods and subject matter of science by critics is seem as a fatal flaw. Ethical problems arise in concrete situations so that moral choices are contextual, requiring inquiry and reflection about options and their potential consequences. Here inquiry is directed toward the most desirable outcomes available.     

Culture,democracy, and the university

This paper examines recent claims that the bodies of knowledge, the standards, and the methods of rational inquiry promulgated by the university are undemocratic, representing a hegemony of Western, middle-class, male culture. It argues that such a view is based on a social construction view of knowledge and points out several problems with this view. It further argues that democracy is not simply a matter of consensus but presupposes rational debate and such rationality is embedded in our cultural traditions of knowledge and inquiry. These traditions are not simply monolithic and static, but are arenas of controversy and debate, and their critical modes of inquiry provide the possibility for evolution and for critique of the traditions themselves. Thus even the criticisms brought forth by the critics of the traditions have grown out of and presuppose the very traditions which they seek to undermine. There is a strong case for investigating the social influences on what has been excluded from the canons of the culture, for reclaiming valuable works which have been neglected, and for critically examining the methodologies of the disciplines. Nonetheless the rejection of rational modes of inquiry seriously undermines the possibility for democracy.     

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.

A SKEPTICAL EDUCATION

A bstract .  In a turn on the familiar notion that learning is inquiry, Dennis Senchuk suggests in this essay that an otherwise exemplary educational curriculum could benefit from the inclusion of some distinctively skeptical modes of inquiry. Senchuk construes two pertinent varieties of skepticism as inquiries into inquiry — one involving an inquiry into the methodology of inquiry, and the other focused argumentatively on specific outcomes of inquiry. The author stops short of interpreting these skeptical modes as the core of critical thinking, but sees them as affording opportunities for valuable linkages between philosophy and education.     

DEWEY'S EPISTEMOLOGY: AN ARGUMENT FOR WARRANTED ASSERTIONS, KNOWING, AND MEANINGFUL CLASSROOM PRACTICE

A bstract .  In an effort to navigate the treacherous path between professionalism and social relevancy, this essay takes up an area of professional philosophy — epistemology — with the intention of reclaiming the integrative role John Dewey held for philosophy and classroom practice. Deron Boyles asserts that epistemology can and should represent an area of inquiry that is relevant and useful for philosophy of education, especially as it develops classroom practices that foster inquiry. He specifically seeks to revive Dewey's conception of warranted assertibility in an effort to show the value of fallibilist epistemology in practical and social teaching and learning contexts. By highlighting the distinctions between traditional epistemology and Dewey's conception of knowing , Boyles demonstrates that epistemology has value insofar as it highlights a more useful, instrumentalist theory of knowing that is applicable to classroom practice.     

The development of dynamic inquiry performances within an open inquiry setting: A comparison to guided inquiry setting

Dynamic inquiry learning emphasizes aspects of change, intellectual flexibility, and critical thinking. Dynamic inquiry learning is characterized by the following criteria: learning as a process, changes during the inquiry, procedural understanding, and affective points of view. This study compared the influence of open versus guided inquiry learning approaches on dynamic inquiry performances among high‐school biology students. We hypothesized that open inquiry students who engage in the inquiry process from its initial stage, participating in the decision making process of asking inquiry questions and planning all aspects of the inquiry, will outperform students who experienced guided inquiry, in terms of developing dynamic inquiry performances. Students were divided into two groups: guided and open inquiry learning approaches. Both groups were followed throughout their 2‐year inquiry learning process. The data sources included interviews, students' inquiry summary papers, logbooks, and reflections. A quantitative content analysis of the two groups, using a dynamic inquiry performances index, revealed that open inquiry students used significantly higher levels of performances in the criteria “changes during inquiry” and “procedural understanding.” However, the study's results indicated no significant differences in the criteria “learning as a process” and “affective points of view.” The implementation of dynamic inquiry performances during inquiry learning may shed light on the procedural and epistemological scientific understanding of students conducting inquiries. © 2009 Wiley Periodicals, Inc.

The Spectrum of Dynamic Inquiry Teaching Practices

The Israeli high school biology curriculum comprises the Biomind program, in which students are engaged in an open inquiry learning process. The dynamic features of open inquiry often pose challenges to teachers in implementing the Biomind program. The current qualitative research shows that facilitating students in a dynamic open inquiry process is multidimensional. Teaching practices cover a wide range of methods, from structured inquiry through guided inquiry to open inquiry. An individual teacher’s profile can be elucidated on the basis of this spectrum. In addition, we realised that teachers often encounter several difficulties in implementing open dynamic inquiry: A dearth of teachers’ scientific knowledge, students’ lack of scientific knowledge and skills, and a restrictive time-frame. This study suggests several areas which should be considered while implementing an on going professional development support for teachers who are engaged in open inquiry teaching.     

K-12 Science and Mathematics Teachers’ Beliefs About and Use of Inquiry in the Classroom

A survey instrument was developed and administered to 1,222 K-12 mathematics and science teachers to measure their beliefs about and use of inquiry in the classroom. Four variables (grade level taught, content area taught, level of support received, and self-efficacy for teaching inquiry) were significantly correlated to two dependent variables, percentage of time that students are engaged in inquiry during a typical lesson and the perceived ideal percentage of instructional time that should be devoted to inquiry. Specifically, elementary school teachers reported using inquiry-based practices more than either middle-school or high-school teachers; similarly, elementary-school teachers believed such practices should be used more often. All groups, however, reported believing in an ideal percentage of time devoted to inquiry instruction that was significantly greater than their reported percentage of time actually spent on inquiry instruction. A disordinal effect was found between grade level taught and content area taught; at the elementary level, science teachers reported both an ideal and actual percentage of time on inquiry higher than those reported by the math teachers, while at the high school level math teachers reported both an ideal and actual percentage of time on inquiry higher than those reported by the science teachers. No correlations were found between typical and ideal percentage of time devoted to inquiry and subject matter content knowledge training, gender, years of teaching experience, or maximum degree earned.

The relative effects and equity of inquiry‐based and commonplace science teaching on students' knowledge,reasoning, and argumentation

We conducted a laboratory‐based randomized control study to examine the effectiveness of inquiry‐based instruction. We also disaggregated the data by student demographic variables to examine if inquiry can provide equitable opportunities to learn. Fifty‐eight students aged 14–16 years old were randomly assigned to one of two groups. Both groups of students were taught toward the same learning goals by the same teacher, with one group being taught from inquiry‐based materials organized around the BSCS 5E Instructional Model, and the other from materials organized around commonplace teaching strategies as defined by national teacher survey data. Students in the inquiry‐based group reached significantly higher levels of achievement than students experiencing commonplace instruction. This effect was consistent across a range of learning goals (knowledge, reasoning, and argumentation) and time frames (immediately following the instruction and 4 weeks later). The commonplace science instruction resulted in a detectable achievement gap by race, whereas the inquiry‐based materials instruction did not. We discuss the implications of these findings for the body of evidence on the effectiveness of teaching science as inquiry; the role of instructional models and curriculum materials in science teaching; addressing achievement gaps; and the competing demands of reform and accountability. © 2009 Wiley Periodicals, Inc.
