Community College Engineering Students’ Perceptions of Classroom Climate and Fundamental Engineering Skills

ABSTRACT

The purpose of this study was to examine community college engineering students’ perceptions of their classroom climate and how these perceptions are related to fundamental skills in engineering. The study was guided by the following research question: How are community college engineering students’ perceptions of their fundamental engineering skills related to their perceptions of classroom climate? Data from a 2009 National Science Foundation sponsored project, Prototype to Production: Processes and Conditions for Preparing the Engineer of 2020 (P2P), which contains information from students in 15 pre-engineering community college programs, were examined. Measures of classroom climate and fundamental skills related to engineering were first established through an exploratory factor analysis. In order to explore differences in student perceptions by individual characteristics and by institution, hierarchical linear modeling (HLM) was used. Results indicated that for community college engineering students, a warmer perception of classroom climate was associated with a higher perception of fundamental engineering skills. At community colleges, class sizes are generally smaller, especially compared to introductory courses at universities, and may provide a warmer climate for students considering beginning their engineering degrees. Given the diversity within community colleges, these institutions may provide an important pathway for underrepresented groups in engineering.     

Preservice elementary teachers' perceptions of their science laboratory instructors in a phenomena-based laboratory and how it impacts their conceptual development

Phenomena-based approaches have become popular for elementary school teachers to engage children's innate curiosity in the natural world. However, integrating such phenomena-based approaches in existing science courses within teacher education programs present potential challenges for both preservice elementary teachers (PSETs) and for laboratory instructors, both of whom may have had limited opportunities to learn or teach science within the student and instructor roles inherent within these approaches. This study uses a convergent parallel mixed-methods approach to investigate PSETs' perceptions of their laboratory instructor's role within a Physical Science phenomena-based laboratory curriculum and how it impacts their conceptual development (2 instructors/121 students). We also examine how the two laboratory instructors' discursive moves within the laboratory align with their's and PSETs' perceptions of the instructor role. Qualitative data includes triangulation between a student questionnaire, an instructor questionnaire, and video classroom observations, while quantitative data includes a nine-item open response pre-/post-semester conceptual test. Guided by Mortimer's and Scott's analytic framework, our findings show that students primarily perceive their instructors as a guide/facilitator or an authoritarian/evaluator. Using Linn's knowledge integration framework, analysis of pre-/post-tests indicates that student outcomes align with students' perceptions of their instructors, with students who perceive their instructor as a guide/facilitator having significantly better pre-/post-outcomes. Additional analysis of scientific discourse from the classroom observations illustrates how one instructor primarily supports PSETs' perspectives on authentic science learning through dialogic–interactive talk moves whereas the other instructor epistemologically stifles personally relevant investigations with authoritative–interactive or authoritative–noninteractive discourse moves. Overall, this study concludes by discussing challenges facing laboratory instructors that need careful consideration for phenomena-based approaches.     

‘Control must be maintained’: exploring teachers’ pedagogical practice outside the classroom

Drawing on qualitative data, this article presents an analysis of six secondary science teachers’ expectations and practices related to teaching outdoors during a professional development programme. Using Foucault’s and Bernstein’s theories of ‘space’, routines and set practices, I argue that participant teachers’ fear of losing control of their students when in contexts outside the classroom was constructed as place specific in terms of boundaries (or lack of), familiarity and disturbance. Teachers’ ‘fearful’ expectations when outside triggered the initial use of regulatory technologies that were frequently more assertive and controlling than their usual classroom practice, resulting in increased authoritative teaching approaches. However, once technologies of power were developed for use outside, teachers were able to translate and apply their normal dialogic teaching approaches from the classroom. The article concludes with a discussion of student self-regulation through collaborative group work as a step towards resolving the tensions between dialogic pedagogy and teaching in new contexts.     

Using a Dialogical Approach to Examine Peer Feedback During Chemistry Investigative Task Discussion

Peer feedback is an inherent feature of classroom collaborative learning. Students invariably turn to their peers for feedback when carrying out an investigative task, and this feedback is usually implicit, unstructured and may positively or negatively influence students’ learning when they work on a task. This study explored the characteristics of verbal peer feedback during a collaborative investigative chemistry task involving New Zealand Year 13 students. During the planning stage of the students’ investigation, the discussions of five pairs of students were recorded and then transcribed. Analysis of transcribed verbal data focused on interactions that involved peer feedback along two dimensions, interactive/non-interactive and dialogic/authoritative (Mortimer and Scott, 2003). The findings indicated that although students adopted a predominantly interactive/authoritative communicative approach, with peer feedback as confirmation or evaluation, they are also capable of a more interactive/dialogic exchange, characterised by elaborative peer feedback. We discuss how this dialogic perspective on peer feedback provides an alternative approach to the analysis and study of student–student interactions during science investigations. The findings should be interpreted in light of the limitations in terms of sample size, grouping and specificity of the coding scheme. Implications for teacher practice are discussed in relation to facilitating peer feedback discourse in the science classroom.     

Gritting it out: The importance of non-cognitive skills in academic mismatch

I examine the importance of non-cognitive skills in the matching process in higher education in the United States. Across two longitudinal data sources, I show that students with lower non-cognitive skills are more likely to undermatch (enrolling in less selective colleges given their academic credentials) and less likely to overmatch. The application process drives the relationship between non-cognitive skills and academic mismatch, as students with low non-cognitive skills are less likely to apply to a well-matched institution. I further show that non-cognitive skills are strong predictors of Bachelor’s degree completion. I propose an alternative definition of undermatch, which additionally considers students’ non-cognitive skills. Under this definition, a smaller share of high-achieving students undermatch in higher education.     

“But at school … I became a bit shy”: Korean immigrant adolescents’ discursive participation in science classrooms

In reform-based science curricula, students’ discursive participation is highly encouraged as a means of science learning as well as a goal of science education. However, Asian immigrant students are perceived to be quiet and passive in classroom discursive situations, and this reticence implies that they may face challenges in discourse-rich science classroom learning environments. Given this potentially conflicting situation, the present study aims to understand how and why Asian immigrant students participate in science classroom discourse. Findings from interviews with seven Korean immigrant adolescents illustrate that they are indeed hesitant to speak up in classrooms. Drawing upon cultural historical perspectives on identity and agency, this study shows how immigrant experiences shaped the participants’ othered identity and influenced their science classroom participation, as well as how they negotiated their identities and situations to participate in science classroom and peer communities. I will discuss implications of this study for science education research and science teacher education to support classroom participation of immigrant students.     

The influence of classroom climate on science process and content achievement of community college students

The effect of two specific classroom climates on learning of science process skills and content achievement in college level science classes was studied. Two classroom climates were established and designated as discovery classroom climate (DCC) and nondiscovery classroom climate (NDCC). The term discovery denotes the degree of freedom the teacher established in classroom interactions, both verbal and nonverbal. Verbal interactions were monitored with the Science Laboratory Interaction Categories. These data indicate that students in the two classroom climates achieved equally as well on learning of biological content of the course, but students in the discovery classroom climate achieved significantly higher scores in science process skills as measured by the Welch Science Process Inventory. This study, conducted in a large, suburban community college, offers some useful information to the person who has educational goals beyond, but including, the learning of science information and concepts, and possibly science process. Students in the less directive discovery climate learned as much content as those in a more directive comparison class-they lost nothing of what is traditionally sought in a college science class. In addition, the discovery climate facilitated the development of science process skills which were significantly better than the comparison class. A five-week intensive class using the discovery climate was found to provide as much content acquisition as the ten-week nondiscovery climate.     

Cases of Science Professors’ Use of Nature of Science

Study provides qualitative analysis of data that answers the following research question: how college science faculty teach science and NOS and incorporate aspects of NOS and the history of science into their undergraduate courses? Study concentrates on four cases and more specifically on three introductory science classes and on four instructors who taught those courses. These instructors were chosen as case studies to explore in greater detail what occurs inside introductory science courses in one particular higher institution in the Northeastern United States. Participants’ teaching styles are presented through a combined and detailed presentation of interview data and classroom observations supported with examples from their classroom activities. Constant comparative approach was used in the process of organizing and analyzing data. Findings revealed that participants preferred to use the traditional teacher-centered lecturing as their teaching style and whose main concern was to cover more content, develop the problem solving skills of their students, and who wanted to teach the fundamental principles of their subjects without paying special importance to the NOS aspects. The study also revealed that other variables of teaching science, such as large class size, lack of management and organizational skills, teaching experience, and instructors’ concerns for students’ abilities and motivation are more important for these scientists then teaching for understanding of NOS.     

Science learning and a Sense of Place in a Urban Middle School

This paper offers an analysis into low-income, urban middle school children's sense of place and what and how their sense of place matters in science learning by focusing on the following questions: In what ways is students' sense of place leveraged in a science classroom? How does the content and context of science class shape how students leverage their sense of place? What learning opportunities emerge when sense of place is leveraged in class? Drawing from an ethnographic investigation into an environmental statistics class in a mid-sized public middle school, we examined sense of place events from their source, process, and outcome perspectives. Our findings are presented from two aspects of sense of place events, (1) characterizing students' sense of place by exploring sources of the sense of place events, and (2) examining processes of how students' sense of place is being leveraged in the episodes. We also examine two kinds of tensions that emerge in the class when sense of place is leveraged by students and acknowledged by the teacher: epistemological tensions (related to what the students are learning) and procedural tensions (related to how they are learning).     

ENHANCING STUDENTS’ COMMUNICATION SKILLS IN THE SCIENCE CLASSROOM THROUGH SOCIOSCIENTIFIC ISSUES

Communication skills are one of the most important competencies for 21st century global citizens. Our guiding presupposition was that socioscientific issues (SSIs) could be used as an effective pedagogical tool for promoting students’ communication skills by increasing peer interactions, stimulating students’ reasoning, and in constructing shared social knowledge. We implemented a SSI program on gene modification (GM) technology to 132 9th graders in South Korea and investigated to what extent this SSI instruction contributed to enhancing students’ communication skills. Data sources included pre- and post-scores on the Communication Skills Questionnaire (CSQ), semi-structured interviews with the students and instructor, and classroom observations. The results demonstrated that SSI instruction could bring about a moderately large impact on students’ ability to understand the key ideas of others and to value others’ perspectives, as well as a marginal positive effect on developing active assertions. However, SSI instruction appeared to have a lesser impact on students’ ability to develop shared understanding. Overall, this research indicates the potential that even a limited SSI classroom could have in terms of promoting students’ communication skills in the context of their regular science class.     

When genres meet: Inquiry into a sixth‐grade urban science class

In this study, we explore oral and written work (plays and rap songs) of students in a sixth‐grade all African‐American urban science class to reveal ways affective and social aspects are intertwined with students' cognition. We interpret students' work in terms of the meeting of various genres brought by the students and teachers to the classroom. Students bring youth genres, classroom genres that they have constructed from previous schooling, and perhaps their own science genres. Teachers bring their favored classroom and science genres. We show how students' affective reactions were an integral part of their constructed scientific knowledge. Their knowledge building emerged as a social process involving a range of transactions among students and between students and teacher, some transactions being relatively smooth and others having more friction. Along with their developing science genre, students portrayed elements of classroom genres that did not exist in the classroom genre that the teacher sought to bring to the class. Students' work offered us a glimpse of students' interpretations of gender dynamics in their classrooms. Gender also was related to the particular ways that students in that class included disagreement in their developing science genre. © 2002 Wiley Periodicals, Inc.

Antecedent factors influencing ethics-related social and socio-scientific learning enjoyment

This study investigates how affective dispositions influencing students’ moral judgments can both shape their response to individual enjoyment from learning ethics (IE-LE) and predict their individual enjoyment from learning socio-scientific issues (IE-LSSI). Tenth-grade participants from southern Taiwan (n?=?770) responded to survey items that support four subscales: science classroom, news media, IE-LE and IE-LSSI. Structural equation modelling analyses of these subscales found them to be empirically separable, structurally reliable and valid for investigating how students’ affective and self-related cognitive responses can predict their self-evaluated state of IE-LE and IE-LSSI. Viewed from the impact contribution of science classroom and news media, learning enjoyment plays a pivotal role in igniting and sustaining students’ personal attention when discussing IE-LE and IE-LSSI in the classroom. The implication of this study is that by encouraging students to think ethically about issues of science and allowing them to investigate SSI-related issues from a variety of news media sources within the classroom context, teachers can provide opportunity for students to explore science issues that may be well connected to their personal enjoyment of ethics and sense of freedom to learn within a science-related classroom environment.     

Children's Reasoning as Collective Social Action through Problem Solving in Grade 2/3 Science Classrooms

Research on young children's reasoning show the complex relationships of knowledge, theories, and evidence in their decision-making and problem solving. Most of the research on children's reasoning skills has been done in individualized and formal research settings, not collective classroom environments where children often engage in learning and reasoning together to solve classroom problems. This study posits children's reasoning as a collective social activity that can occur in science classrooms. The study examined how children process their reasoning within the context of Grade 2/3 science classrooms and how the process of collectivity emerges from classroom interactions and dialogue between children as they attempt to solve their classroom problems. The study findings suggest that children's reasoning involves active evaluation of theories and evidence through collective problem solving, with consensus being developed through dialogical reasoning.     

Going beyond textbooks: a study on seamless science inquiry in an upper primary class

This paper reports an initial study on investigating inquiry-based learning in science in an upper primary class guided by an inquiry-based learning model in a seamless learning environment. Two questions are addressed: (1) how students advanced their domain knowledge?; and (2) how students developed their inquiry skills? One teacher and 27 Grade-four students from a local primary school were involved in the study. Six inquiry-based learning lessons focusing on a scientific “rustproofing” learning unit were conducted in a seamless learning environment, initiated in a digital classroom and extended to online discussions on a social network platform. Qualitative data were collected and analysed over two weeks. The results show ways that the students advanced their domain knowledge and developed their inquiry skills.     

Neighborhood Science Stories: Bridging science standards and urban students’ lives

Shelter, distribution of resources, adaptation and food sources are all key topics in teaching fifth grade students ecosystems. These terms and ideas are often presented in value neutral terms in the standard science curriculum. These terms have radically different connotations in different communities. In this paper students’ fictional narrative about the community and ecosystem provide insight into how experiences in an urban community change perceptions and understandings of science content. By analysing the students’ stories, the teacher is provided with a critical lens through which to rethink the content being taught, the examples and discussions about the content and how that content is being presented in the classroom. In this example, students’ own understanding of how resources are allocated justly in society stand in contrast to the value neutral presentation of resource distribution in the standard curriculum.     

The role of fictive kinship relationships in mediating classroom competition and supporting reciprocal mentoring

Previous research has suggested that competitive classroom environments can play a role in perpetuating race and class inequalities. However, classroom competition can also promote learning, and eliminating it could do students a disservice. This paper draws on research literature and data from a qualitative study by Konstantinos Alexakos, Jayson K. Jones, and Victor H. Rodriguez on fictive kinship in order to explore the conditions under which classroom competition could benefit students from non-dominant groups. Based on their data, I argue that competition can support the learning of students from non-dominant groups, provided that it takes place in the context of strong emotional ties and successful interaction rituals. I also discuss the role of competition in facilitating reciprocal mentoring, as students seek knowledge and skills from each other in order to participate in solidarity-building classroom interactions. In addition, I show how their study challenges a perceived dichotomy between competition and cultural orientations towards communalism.     

Making learning interesting and its application to the science classroom

Generations of students are graduating from secondary school disinterested in post-secondary study of science or pursuing careers in science-related fields beyond formal education. We propose that destabilising such disinterest among future students requires science educators to begin listening to secondary school students regarding their views of how science learning is made interesting within the science classroom. Studies on students’ interest in response to instructional strategies applied in the classroom communicate the opinions (i.e. the ‘voice’) of students about the strategies they believe make their classroom learning interesting. To this end, this scoping study (1) collects empirical studies that present from various science and non-science academic domains students’ views about how to make classroom learning interesting; (2) identifies common instructional strategies across these domains that make learning interesting; and (3) forwards an instructional framework called TEDI ([T]ransdisciplinary Connections; Mediated [E]ngagement; Meaningful [D]iscovery; and Self-determined [I]nquiry), which may provide secondary school science teachers with a practical instructional approach for making learning science genuinely interesting among their students within the secondary school science classroom context.     

Use of First‐hand and Second‐hand Data in Science: Does data type influence classroom conversations?

In this paper, we examine how students discuss and interpret data and whether these actions vary depending on the type of data they analyse. More specifically, we are interested in whether students perform differently when analysing first‐hand data, which they collect themselves, compared with second‐hand data provided to them. Our data analysis focused on two classrooms using two different curriculum units, chemistry in Grade 7 and biology in Grade 8, collected during the 2002/03 school year from a Mid‐western urban middle school in the USA. We analysed classroom videotape associated with lessons in which students discussed first‐hand and second‐hand data both in small group settings and full class discussions. We found the two types of data offer different benefits and limitations, suggesting that both types of data are important for students to work with as they develop skills in scientific inquiry practices. We discuss the characteristics of classroom discussions around different data sources as well as implications for the design of curriculum materials, instructional environments, and student learning in science.
