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.     

Building learning communities with distance learning intruction

The results presented in this study represent only one of four assigned discussion board activities from only one course. However, these results are not atypical of the amount or nature of student engagement in successive discussion board assignments to these same 23 graduate students. By the final of the four on-line discussions, student engagement did decrease slightly, but still remained well above the assigned requirements. Also, similar patterns of high frequency of student involvement were found in other courses using the same type of on-line discussion board assignments. An additional anecdotal observation was completed by the course instructor; after the first on-line activity had been completed and the students re-convened on campus for class, class members appeared more comfortable and more engaged during in class discussions. In summary, the results of this study indicate that specific types of on-line instruction are capable of developing learning communities among on-line learners and creating a satisfying learning experience.     

Facilitating online discussions effectively

This article presents a synthesis of the theoretical and research literature on facilitating asynchronous online discussions effectively. Online courses need to be designed so that they provide motivation for students to engage in productive discussions and clearly describe what is expected, perhaps in the form of a discussion rubric. Additionally, instructors need to provide discussion forums for socio-emotional discussions that have the goal of nurturing a strong sense of community within the course as well as group discussion forums for content-and task-oriented discussions that center on authentic topics. In order to facilitate discussions effectively, instructors should generate a social presence in the virtual classroom, avoid becoming the center of all discussions by emphasizing student–student interactions, and attend to issues of social equity arising from use of different communication patterns by culturally diverse students [e.g., Garrison, D. R., Anderson, T., and Archer, W. (2001). Critical thinking, cognitive presence, and computer conferencing in distance education. The American Journal of Distance Education, 15(1), 7–23; Rovai, A. P. (2003). Strategies for grading online discussions: Effects on discussions and classroom community in Internet-based university courses. Journal of Computing in Higher Education, 15(1), 89–107].     

Why Should We Group Students Within-Class for Learning?

The purpose of this article is threefold. First, we bring to the attention of the European and international research community the research evidence concerning within-class grouping. In a previous quantitative review, we computed 103 independent effect sizes from studies comparing within-class instruction and whole class instruction. The mean weighted effect size (ES) of within-class versus no grouping on student achievement was 0.17, which was significantly greater than zero (p < .05). We also reported that the findings were statistically heterogeneous and explored which of 26 study features accounted for the variability. Second, we address the issues related to our research integration raised by Prais (1998, 1999). We argue that our review focused only on grouping effects on students, not other features of classroom organization or teacher outcomes. We also believe that our data suggest that Continental Education would be further enhanced by the use of small group instruction. In particular, our findings are: useful; not so variable as to be meaningless; provide evidence of beneficial effects for students of all relative abilities; are thorough and detailed; and provide a rather complete picture of the available evidence. Third, we elaborate further on the pedagogical techniques which encourage effective small group instruction. We describe cooperative learning in general, the important elements of positive interdependence and individual accountability in particular, and summarize reviews of research on its effectiveness. We remain convinced that educators should group students within-class for learning and rely on the research evidence for guidance in doing so.     

Student Teaching Supervision: Roles and Routines

The middle school years are a critical time in the physical, intellectual, and moral growth of young adolescents. This article examines how film can be used to engage students in moral-dilemma discussions to promote critical thinking and character development. The authors argue that the use of film in the classroom can challenge students to expand and analyze their own values and beliefs by examining moral dilemmas in popular films. In addition, the article provides readers with a filmography of useful character education-related films for the middle school classroom. The primary focus of this article is to provide teachers with an engaging and dynamic form of instruction to help middle school students become responsible citizens of character.     

Student affective reactions and the teaching and learning of foreign languages

This chapter argues for the recognition of the importance of student affective reactions in discussions of second language learning and teaching. It is argued that language learning is a particularly intense and ego-involving undertaking which requires a positive emotional stance on the part of the learner. The chapter reviews literature on how affective reactions — particularly motivation for language learning, foreign language anxiety, and student beliefs about language learning — impact on the language learning process and makes suggestions as to how teachers can promote positive affective characteristics. As affective variables represent the learner's willingness to engage in the activities necessary to develop second language proficiency, it is essential that teachers make the emotional needs of their students an instructional priority.     

Using internet assessment tools for health and physical education instruction

Conclusions Physical education should provide opportunities for students to participate in activities that promote fitness and well-being. Implementing best practices into the physical education curriculum can contribute to the understanding and application of a healthy lifestyle for students. Technology applied in the physical education curriculum can provide an opportunity for improved instruction and enhanced student learning in physical education. The current study showed that students not only enjoyed working with computer technology but also preferred this interactive instructional method to a lecture method of instruction. The use of technology within the physical education program seemed to motivate students to engage with the material presented. After completing the web-based activities, students also seemed to be aware of their eating and physical activity habits and the changes that they needed to make in their lifestyles. They also expressed positive attitudes toward the use of technology in their physical education class. This study supports Cradler’s (1992) observation that outcomes will be positive when the effective physical educator uses the appropriate technology with sound pedagogical strategies and applicable content in their curriculum.     

A comparison of level of understanding of eighth‐grade students and science student teachers related to selected chemistry concepts

The aim of this study is to investigate and compare level of understanding of eighth‐grade students and student teachers in their final year in the science education department related to concepts of solution, gas, and chemical change. A qualitative and quantitative methodology was used for this investigation. Open‐ended questions and group discussion methods were used for data collection. Moreover, to examine how students visualize these concepts, students were asked to make drawings. The questions were administered to 50 students in Grade 8 and 50 student teachers in the science education department. Group discussions were conducted with 6 students and 6 student teachers. There were surprisingly similar alternative conceptions by both the students and the student teachers despite more instruction on these topics in the education of the student teachers. Based on the results, some suggestions are presented. © 2005 Wiley Periodicals, Inc. J Res Sci Teach

How Good Are Our Schools

ABSTRACT

Research suggests a positive relationship between schools’ efforts to engage parents and parents’ involvement in their child's education. The authors investigated school socioeconomic status, school size, grade level, and student–teacher ratio as predictors of schools’ efforts to engage parents of students receiving special education services. The dependent variable was the Schools’ Efforts to Partner with Parents’ Scale, which has been validated for states’ use in their federal accountability systems. Mean school-level scores were calculated for 265 schools in a large southeastern state. Results indicated that student–teacher ratio was the strongest predictor of parents’ perceived school engagement efforts. Implications are drawn for ways in which all schools, including those with high student–teacher ratios, can improve their collaboration with parents of students receiving special education services.     

The Challenge of Change

A large literature establishes the benefits of discussions for stimulating student engagement and critical thinking skills. However, we know considerably less about the differential effects of various discussion environments on student learning. In this study, we assess student perceptions concerning the benefits of discussions in an upper-level political science class. We compare how students evaluated discussions in the whole-class environment, in small face-to-face discussion groups, and in online discussion groups. Overall, according to student surveys, small discussion groups elicited the highest student satisfaction and scored highest in critical thinking skills, while online discussions provided the best forum to express thoughts. While they did not favor all-class discussions, students reported that this format, too, provided benefits.     

Overcoming MSW Students' Reluctance to Engage in Research

Social work students are typically reluctant to engage in research. The research partnership model takes a service-learning approach, allowing students to work with data from a community agency and resulting in a final paper with all the sections of an empirical journal article. Use of this model in teaching social work research enhances student motivation, learning, and skills through hands-on activities within an authentic context, and by using group support with individual accountability, structured and incremental learning opportunities, and teaching from a strengths-based perspective.     

Professional development in classroom discussion to improve argumentation: Teacher and student outcomes

The purpose of this study was to examine the effects of a year-long professional development program in classroom discussion designed to improve students' argumentation skills in language arts classes. Twenty-six fifth-grade teachers and their 471 students at two research sites participated: 14 teachers in the experimental condition, who received the professional development, and 12 teachers in the comparison condition. Results showed that the professional development led to statistically significant improvements in the quality of teachers' facilitation and student argumentation during discussions, and in students' performance on individual argumentative reading and writing tasks following the discussions, at the end of the year. Findings suggest that the professional development for teachers resulted in strengthened student abilities to connect positions with relevant reasons and evidence, and that argumentation skills acquired in the discussions may have transferred to students’ individual argumentation, at least for reading outcomes.     

Effects of Peer-Led Online Asynchronous Discussion on Undergraduate Students' Cognitive Achievement

Abstract

This study investigated the effect of peer leadership on students' cognitive achievement in online asynchronous discussions. Undergraduate students from a large online course were randomly assigned into groups for four asynchronous discussions, with each group having two to three peer leaders. Results of the mixed-method analysis revealed that the quality of student leaders' lower-order cognitive achievement in online discussion was significantly better than that of student responders. Student leaders' higher-order cognitive level achievement in online discussion had at least the same quality as that of student responders. Moreover, both students' higher-order and lower-order cognitive achievement in discussions had positive and moderate correlation with students' course achievement. Further study should focus on methods to maximize student responders' cognitive achievement in online peer-led discussions.     

The effects of group composition on achievement,interaction, and learning efficiency during computer-based cooperative instruction

This study investigated the effects of cooperative group composition, student ability, and learning accountability on achievement, interaction, and instructional efficiency during computer-based instruction. A total of 125 sixth- and seventh-grade students were randomly assigned to heterogeneous or homogeneous dyads. Groups were designated as having either group or individual account-ability for mastery of lesson content. Cooperative dyads completed a tutorial on a novel symbolic mathematics topic, featuring basic symbol learning and application of the symbols. Indicators of ongoing cooperation were collected during instruction. Five days later, students completed a posttest. Low-ability students interacted more and completed the instruction more efficiently in heterogeneous than in homogeneous groups. High-ability students completed the instruction more efficiently in homogeneous than in heterogeneous groups. Cooperation was significantly related to achievement for heterogeneous ability groups, but not for either homogeneous high- or low-ability students.     

Computer-Assisted Instruction Augmented with Planned Teacher/Student Contacts

This paper discussed a study of the differences in student learning achievement and retention in a college-level statistics course taught in a variety of teaching/learning environments. Statistical test results revealed that students experiencing a CAI environment performed no differently on achievement or retention tests than students experiencing a traditional lecture/discussion environment. However, students experiencing an “enriched” CAI environment (CAI plus planned teacher/student contacts) performed significantly better on achievement tests than students experiencing any of several other environments, including: lecture/discussion, lecture/discussion supplemented with planned teacher/student contacts, PI texts, PI texts supplemented with planned teacher/student contacts, and CAI.     

What Motivates Today’s Criminal Justice Student to Become an Engaged Learner?

The use of student-centered High Impact Practices (HIPs) has become increasingly popular across university and college faculty. HIPs increase student development of critical thinking, problem solving, and communication skills. HIPs also provide students the opportunity to engage in real-world application of course knowledge. While HIPs increase student engagement and intrinsic motivation, little research has explored student perception of these concepts. This article describes a pilot course offered to upper level criminal justice students that incorporated three HIPs: undergraduate research, collaborative assignments, and service/community-based learning. Semi-structured interviews were used to facilitate individual student discussion regarding their perceptions and experiences of the course related to their level of motivation and engagement as compared to traditional classes. Results indicated student expectations for the course were exceeded; students believed the course would positively impact their future career/education plans; and the HIPs motivated the students to engage more than their traditional lecture-oriented courses.     

Is DNA Alive? A Study of Conceptual Change Through Targeted Instruction

We are involved in a project to incorporate innovative assessments within a reform-based large-lecture biochemistry course for nonmajors. We not only assessed misconceptions but purposefully changed instruction throughout the semester to confront student ideas. Our research questions targeted student conceptions of deoxyribonucleic acid (DNA) along with understanding in what ways classroom discussions/activities influence student conceptions. Data sources included pre-/post-assessments, semi-structured interviews, and student work on exams/assessments. We found that students held misconceptions about the chemical nature of DNA, with 63 % of students claiming that DNA is alive prior to instruction. The chemical nature of DNA is an important fundamental concept in science fields. We confronted this misconception throughout the semester collecting data from several instructional interventions. Case studies of individual students revealed how various instructional strategies/assessments allowed students to construct and demonstrate the scientifically accepted understanding of the chemical nature of DNA. However, the post-assessment exposed that 40 % of students still held misconceptions about DNA, indicating the persistent nature of this misconception. Implications for teaching and learning are discussed.     

The Effects of Motivational Instruction on College Students' Performance on Low-Stakes Assessment

Assessments of student learning outcomes (SLO) have been widely used in higher education for accreditation, accountability, and strategic planning purposes. Although important to institutions, the assessment results typically bear no consequence for individual students. It is important to clarify the relationship between motivation and test performance and identify practical strategies to boost students' motivation in test taking. This study designed an experiment to examine the effectiveness of a motivational instruction. The instruction increased examinees' self-reported test-taking motivation by .89 standard deviations (SDs) and test scores by .63 SDs. Students receiving the instruction spent an average of 14 more seconds on an item than students in the control group. Score difference between experimental and control groups narrowed to .23 SDs after unmotivated students identified by low response time were removed from the analyses. The findings provide important implications for higher education institutions which administer SLO assessments in a low-stakes setting.
