Chemistry as a subject is difficult to learn and understand, due in part to the specific language used by practitioners in their professional and scientific communications. The language and ways of representing chemical interactions have been grouped into three modes of representation used by chemistry instructors, and ultimately by students in understanding the discipline. The first of these three modes of representation is the symbolic mode, which uses a standard set of rules for chemical nomenclature set out by the IUPAC. The second mode of representation is that of microscopic, which depicts chemical compounds as discrete units made up of atoms and molecules, with a particular ratio of atoms to a molecule or formula unit. The third mode of representation is macroscopic, what can be seen, experienced, or measured directly, like ice melting or a color change during a chemical reaction. Recent evidence suggests that chemistry instructors can assist their students in making the connections between the modes of representation by incorporating all three modes into their teaching and discussions, and overtly connecting the modes during instruction. In this research, chemistry teachers at the community college level were observed over the course of an entire semester, to evaluate their instructional use of mode of representation. The students of these teachers were tested prior to and after a semester's worth of instruction, and changes in the basic chemistry conceptual knowledge of these students were compared. Additionally, a subset of the overall population that was pre- and post-tested was interviewed at length using demonstrations of chemical phenomenon that students were asked to translate using all three modes of representation. Analysis of the instruction of three community college teachers shows there were significant differences among these teachers in their instructional use of mode of representation. Additionally, the students of these three teachers had differential and statistically significant achievement over the course of the semester. This research supports results of other similar studies, as well as providing some unexpected results from the students involved.

Description
Sustainability is a relatively new topic that has transcended traditional disciplinary boundaries. Since faculty members have been trained in traditional disciplines, developing curriculum for and teaching sustainability presents both a great opportunity and a challenge. In order to embrace sustainability education and develop and implement new curriculum, faculty members have to expend a large amount of effort and time. Moreover, faculty members require support and help of professional development programs. All these issues and problems demonstrate a need for this research study. The purpose of this study was to analyze the processes and procedures used by a small sample of faculty members of Greenville Community College District (GCCD) to integrate sustainability into the curriculum and classroom. The diffusion of innovation was identified as the conceptual framework, and qualitative case study methodology was used. The findings revealed three major themes why faculty members were interested in sustainability education: love of nature, inherent nature of their discipline, and commitment to issues of equity. The findings revealed that sustainability is taught using pedagogical tools such as experiential learning, problem-based learning, inquiry-based learning, and a heavy focus on research. As lesson plans were developed, appropriate assessment tools were created. The participants interviewed identified several barriers for teaching interdisciplinary courses, among which time constraints and increase in workload emerged as common themes. The study found that strategies for helping mainstream faculty members embrace sustainability education were time, rewards, recognition, support and encouragement, motivation of students, and creating a network of early adopters as mentors.

The role of an art educator is characteristically dualistic and paradoxical. Not only are most art educators trained as artists, but they also receive instruction on theories and practices used in art education. The purpose of the study was to examine how community college ceramic instructors identify themselves within their dual roles as teacher-artists. I studied if and how the teacher-artist places emphasis on one position over the other, or how they successfully synthesized these positions. I also investigated the phenomenon by considering the why, how and which role they accentuated, as well as it affects and influences on their creative and teaching activities. By using a feminist theory, the research uncovered information on how gender may or may not affect their careers, as well as their identities.

ABSTRACT
Community colleges are open access institutions, striving to meet the needs of all students regardless of level of academic preparation or achievement. Community college student enrollment continues to rise; however, the success of community college students has not increased accordingly. A significant number of students begin at community colleges academically underprepared, placing into developmental level courses in English, reading, and math. Success rates for students in developmental level courses, however, lag behind success rates of students enrolled in college-level courses.
To improve course success rates and the overall success of students in developmental level courses, I designed a professional development experience to strengthen developmental education faculty members’ social capital, connecting faculty with peers who also teach developmental level courses. Twelve full-time faculty members participated in an interdisciplinary Professional Learning Network (PLN), where they engaged in shared critical dialogue and conducted and received a peer observation.
I designed a mixed methods action research study where participants completed a pre- and post-survey measuring the influence of this professional development experience on their social capital and their use of effective teaching practices. Additionally, participants completed reflective journal responses, and I interviewed six participants to determine if participation in the PLN and conducting and receiving an interdisciplinary peer observation would transform their teaching practice.
Quantitative results indicated that participation in the PLN had little influence on developing participants’ social capital and little influence on transforming teaching practice. The qualitative data indicated that participants’ confidence in their teaching practice increased. Participants’ social capital was strengthened as they developed an informal support network that grew from a sense of trust and common purpose. Furthermore, interacting with instructors from a different discipline expanded their ideas about effective teaching practices. Ultimately, participation in the PLN and conducting and receiving a peer observation led some participants to consider a transformation of individual teaching practices and in a few instances, modifications to teaching philosophy.

Description
As open-door institutions, community colleges provide access to students from a wide range of backgrounds, experiences, and cultures. Yet while enrollment of students of color in community colleges continues to increase, representation by faculty of color has not. This qualitative study investigated community college faculty search committee members' implicit and subjective observations, values, and beliefs about ethnic/racial diversity in order to gain an understanding of how they may influence the faculty hiring process. The researcher interviewed 12 subjects-- administrators and faculty members at three community colleges in a large district in the southwest region of the United States--who served on faculty search committees from 2006-2009. Findings revealed three major themes: (a) the communication of diversity; (b) search committee dynamics with the sub-themes of role of the chair, role of administration, and the issue of time; and (c) subjects' observations, values, and beliefs, with the sub-themes of conflict, the idea of a "good fit," colorblindness, self-perception of having attained enlightenment about diversity, and the blaming of applicant pools. Discussion of the results was facilitated by utilizing three critical race theory constructs: (a) the pervasiveness of racism as ordinary and normal, (b) the use of Whiteness as the normative standard, and (c) the rejection of liberalism. The findings support the literature's assertion that colleges and faculty search committees can publically claim to value diversity but engage in practices that are incongruent with such claims. Despite the best institutional rhetoric on faculty diversity, failure to address search committee members' values, beliefs, and behaviors will result in little change. Communication and effective leadership can help increase faculty of color representation at community colleges. Communication about the relevance and practical application of diversity should be strong and consistent. Additionally, search committee definitions of "qualified" need to be challenged specific to members' colorblindness and beliefs in the effectiveness of meritocracy. Moreover, leadership is needed to advocate and hold people responsible and accountable for inclusive practices. Critical race theory served as a useful theoretical framework to identify the obstacles and analyze policies and power structures that facilitate underrepresentation of faculty of color in community colleges.

Description
Health science students like students in many disciplines exhibit difficulty with transferring content from one course to another. For example, the problem explored in this study occurred when overlapping concepts were presented in introductory biology and chemistry courses, but students could not transfer the concepts to the other disciplinary course. In this mixed method action research study, the author served as facilitator/leader of a group of colleagues tasked with investigating and taking steps to resolve this student learning transfer problem. This study outlines the details of how an interdisciplinary community of practice (CoP) formed between chemistry and biology faculty members at a community college to address the problem and the benefits resulting from the CoP. Quantitative and qualitative data were obtained from transcripts of meetings of the faculty members, notes from other formal and informal meetings, classroom visits, a questionnaire containing Likert and open-ended items and interviews. Transcripts, notes, and interviews were coded to determine common themes. Findings suggested the CoP was an effective means to deal with the matter of student transfer of content across courses. In particular, the CoP agreed to use similar terminology, created materials to be used consistently across the courses, and explored other transfer specific approaches that allowed for transfer of course content. Finally, the benefits of the CoP were due in large part to the collaboration that took place among participants.
