Learner-Centered Inquiry in Undergraduate Biology: Positive Relationships with Long-Term Student Achievement

We determined short- and long-term correlates of a revised introductory biology curriculum on understanding of biology as a process of inquiry and learning of content. In the original curriculum students completed two traditional lecture-based introductory courses. In the revised curriculum students completed two new learner-centered, inquiry-based courses. The new courses differed significantly from those of the original curriculum through emphases on critical thinking, collaborative work, and/or inquiry-based activities. Assessments were administered to compare student understanding of the process of biological science and content knowledge in the two curricula. More seniors who completed the revised curriculum had high-level profiles on the Views About Science Survey for Biology compared with seniors who completed the original curriculum. Also as seniors, students who completed the revised curriculum scored higher on the standardized Biology Field Test. Our results showed that an intense inquiry-based learner-centered learning experience early in the biology curriculum was associated with long-term improvements in learning. We propose that students learned to learn science in the new courses which, in turn, influenced their learning in subsequent courses. Studies that determine causal effects of learner-centered inquiry-based approaches, rather than correlative relationships, are needed to test our proposed explanation.

Promoting Science Among English Language Learners: Professional Development for Today’s Culturally and Linguistically Diverse Classrooms

We describe a model professional development intervention currently being implemented to support 3rd- through 5th-grade teachers’ science instruction in 9 urban elementary schools with high numbers of English language learners. The intervention consists of curriculum materials for students and teachers, as well as teacher workshops throughout the school year. The curriculum materials and workshops are designed to complement and reinforce each other in improving teachers’ knowledge, beliefs, and practices in science instruction and English language development for ELL students. In addition to these primary goals, secondary goals of the intervention included supporting mathematical understanding, improving scientific reasoning, capitalizing on students’ home language and culture, and preparing students for high-stakes science testing and accountability through hands-on, inquiry-based learning experiences.

Instructional Intervention is the Key: Supporting Adolescent Information Seeking

This research sought to examine the information seeking processes employed by Canadian junior high school students from Inuvik, Northwest Territories and Beaumont, Alberta when using CD-ROM encyclopedias and when completing inquiry-based learning activities. The first study revealed that participants needed both instruction and practice to develop the skills and strategies needed for full-text searching of CD-ROM encyclopedias. The participants tended to use search terms only from the original question, had difficulty selecting topics and articles from the retrieved list, and did not read long articles as carefully as short articles. The second study revealed that students needed support throughout the inquiry-based learning experience and that using Kuhlthau's Information Search Process model as a guide for affective stages was useful. Participants needed time to explore, discuss, and read before finding a focus for their inquiry. Both studies found that participants wanted time to talk and discuss and that instruction was important to help students move forward in their searching and learning.

Using Think Alouds, Think Afters, and Think Togethers to Research Adolescents’ Inquiry Experiences

This article presents three research methods—Think Alouds, Think Afters, and Think Togethers—as ways of gathering data to describe the experiences of adolescents during instructional activities. These verbal report methods were used in two studies that examined the information-seeking processes of adolescents in Inuvik, Northwest Territories and Beaumont, Alberta. The first study revealed that participants needed both mediation (instruction and support) and practice to develop the skills and strategies needed for full-text searching of electronic encyclopedias. The second study revealed that students needed mediation (instruction and support) throughout an inquiry-based learning experience and that using Kuhlthau’s (1993) Information Search Process model as a guide for cognitive and affective mediation was useful. The Think Alouds, Think Afters, and Think Togethers allowed the researcher to collect data about the adolescents’ experiences of information-seeking; the data-gathering processes also provided the participants with a deeper understanding of their own experiences of instructional activities. I conclude the article with recommendations to enhance researchers’ use of verbal report methods with adolescents.

Neuroscience Workshops for Fifth-Grade School Children by Undergraduate Students: A University–School Partnership

The National Science Education Standards recommend that science be taught using inquiry-based approaches. Inspired by the Dana Alliance for Brain Initiatives, we examined whether undergraduate students could learn how to conduct field research by teaching elementary school children basic neuroscience concepts in interactive workshops. In an inquiry-based learning experience of their own, undergraduate psychology students working under the close supervision of their instructor designed and provided free, interactive, hour-long workshops focusing on brain structure and function, brain damage and disorders, perception and illusions, and drugs and hormones to fifth-graders from diverse backgrounds, and we assessed the effectiveness of the workshops using a pretest-post-test design. The results suggest that the workshops enhanced the children's knowledge of neuroscience concepts as measured using pre- and post-open-ended assessments. The undergraduates also found their learning experience engaging and productive. The article includes detailed descriptions of the workshop activities, procedures, the course in which the undergraduates implemented the workshops, and guidance for future university-school collaborations aimed at enhancing science literacy.

Dilemmas of Teaching Inquiry in Elementary Science Methods

Because various definitions of inquiry exist in the science education literature and in classroom practice, elementary science methods students and instructors face dilemmas during the study of inquiry. Using field notes, instructor anecdotal notes, student products, and course artifacts, science methods course instructors created fictional journal entries to represent the experiences of both the instructors and students during instruction on inquiry. Identified dilemmas were varying definitions of inquiry, the struggle to provide sufficient inquiry-based science-learning experiences, perceived time constraints, determining how much course time should be slated for science instruction versus pedagogy instruction, instructors' and students' lack of inquiry-based learning experiences, grade versus trust issues, and students' science phobia. Instructors' attempts at dealing with these dilemmas included using analogies, increased field-experience time, modeling, and detailed rubrics.

Inquiry-based learning: An instructional alternative for occupational therapy education.

An inquiry-based learning (IBL) approach was used as the model of instruction in one of three sections offered annually to large introductory occupational therapy classes in a Canadian university during 1994/5, 1995/6, 1996/7. Students' final grades in this pre-entry course form part of the grade point average on which admission to the BSc OT programme is based. The IBL model was employed to (1) increase the amount of student-directed learning, (2) increase the amount of independent problem-solving, (3) increase student-instructor interaction within the learning situation, and (4) reduce the number of in-class hours for students. This study is an evaluation of whether students from the IBL sections would subsequently do as well as those from other sections in selected junior professional courses. Students from the three IBL sections (n=47) were peer matched to students who had completed other sections of the introductory course, but were part of the same admission cohort (n=68). Their grades in three junior professional courses were compared at the end of their first year in the BSc OT programme. Results indicated that students from the IBL sections did at least as well as those from other sections where a different instructional approach was used, and those from the IBL sections in 1994/5 and 1996/7 each did significantly better on two of the junior professional courses used as the outcome measure: therapeutic occupation and assessment and evaluation techniques. Students reported that the IBL experience stimulated them to learn more about the field, helped them develop problem-solving skills in relation to occupational therapy, and enabled them to learn more about career opportunities in occupational therapy. Mature students were more positive about the IBL approach than students in their first year of university.
