The purpose of this study was twofold: Purpose 1 was to determine to what degree the desirable characteristics of a quality science program based upon the national standards as developed by the National Science Teachers Association (NSTA) were actually being achieved as perceived by the public school secondary science teachers and supervisory personnel in Tennessee. Purpose 2 was to determine to what degree the quality components of a good science curriculum based upon the national standards as developed by the National Science Teachers Association (NSTA) were considered to be desirable components of a quality secondary science program by the public school secondary science teachers and supervisory personnel in Tennessee. A random sample was taken from the target population of 1566 public, secondary science teachers and supervisory personnel, grades 9 through 12, from 125 school systems in Tennessee with the same core science offerings which if successfully completed, would allow students entrance into Tennessee Board of Regents institutions. A total of 20 research hypotheses were tested in the null format at the.05 level of significance using a two-tailed test. The Kruskal-Wallis One Way Analysis of Variance test was used to determine the difference in the ordinal data of the two independent groups. The Chi-Square test was obtained on those hypotheses dealing with ordinal and nominal data. The results of the study suggested that significant relationships existed between the perceived level of desirability of a school's science program and the perceived level of achievement of that program for all respondents in regard to the levels of: science background, general education, professional education, professional activities and development, contributions to the profession, and professional attitudes.

This population study of the certification qualifications of the secondary science teachers of the Upper East Tennessee region in 1984-85 was conducted to determine if there was a qualification shortage in any science-teaching area at the beginning of the Comprehensive Education Reform Act (CERA). Data were obtained from the Tennessee State Department of Education Preliminary Report Forms for Staff. Subject certification data and 1984-85 teaching assignment were analyzed to find percentages of infield, out-of-field teaching and the size of the internal pool of active certificated science teachers who were not teaching. Results of these analyses were presented for each system and compiled for the region. Results indicated that qualification shortages as measured by out-of-field teaching were present in all but one regional system ranging from a low of 12% for chemistry to a high of 91% for earth/space science. General science was 22%; biology was 34%; and physics was 47%. Regionally, there were wide variations of these out-of-field teaching percentages. Comparing the internal pool of teachers certificated to teach in the science areas with the number of out-of-field teachers, in all cases, except earth/space science, there was a surplus of internal pool science teachers within the region and within most of the school systems. Implications of this study for school administrators included: (1) the need for studying their science teaching populations and making any changes possible from their internal pools to alleviate any discovered qualification shortages; (2) the prediction that the pattern documented for Upper East Tennessee will be found statewide perhaps with lower in-field chemistry and higher earth/space science teaching percentages; and (3) that without statewide requirements that all teachers be certificated in all subjects they are teaching, the qualification shortage in science teachers will likely continue. Recommendations of the study include sharing the results with the school systems and others involved, setting up a position to do this on an on-going basis for the whole state, doing a follow-up study to see the effect of the science scholarship part of CERA, and publicizing need areas to prospective teachers.

Strong educators always look for different ways to excite and enthrall their students in the curriculum. The field of science education often loses student interest due to the complexities and vocabulary found in the scientific realm. Incorporating music into the classroom has shown positive results as a way to integrate student learning and a different way of facilitating students in the learning process (Brewer, 1992; Davies, 200). Resources for implementing the integration of music and science exist throughout the Internet in a variety of mediums. This study looks at the availability of said resources and the concepts they cover, for what students they are intended for, how are they intended to be used and the level of accuracy they maintain. Those resources upholding the accuracy desired for use in the classroom were then compiled onto one webpage for use by elementary science educators. The webpage is open and free to the public and may be shared.

Biochemistry has continued to be one of the most complex and important subjects in science education. The purpose of this research is to investigate active learning implementation methods in a Biochemistry I context to determine the most effective means of preparing current science undergraduates. Two Biochemistry I classes over two semesters were analyzed in this study, with class A using a variable active learning schedule and class B using a consistent active learning schedule. Four aspects were analyzed to determine active learning validity: perception of different active learning properties, standardized final exam grades, class grade, and teaching implementation. The consistent schedule of daily active learning in class B showed an increase in mean final exam score by 12.72%, significantly improved mean student grade in the class from a high C to a low B (p= 0.0038), and comparing student perception of active learning data, showed a significant decrease in student desire for passive learning (p= 0.025), increased desire for active learning (p= 0.022), and increased desire for flipped classrooms (p= 0.042) after first experiencing opposite results in the first semester of implementation which had increased desire for passive learning (p= 0.003) and teacher-centric learning (p= 0.026). A variable active learning schedule showed no significant values besides an increase in individual learning desire (p= 0.037) and a marginally significant increase in desire for passive learning (p= 0.053) both in its second semester of implementation. This research supports that a consistent, daily active learning curriculum making up approximately 40-50% of daily instruction is preferable compared to a variable lecture schedule with active learning days in between lecture days in undergraduate Biochemistry I large-class instruction given that professors perform it over multiple semesters.

The purpose of this study was to determine the effects of an experiential program on the occupational identity, access, and career maturity of Black and Latino students from low socioeconomic backgrounds. Data shows these students to be underrepresented in STEM fields. Student interest and access are noted in the literature to be amongst the reasons minorities do not pursue a career in STEM related fields. Jobs within the STEM industry pay considerably more than non-STEM related jobs, access to these jobs can help individuals transform their socioeconomic status. Lack of access and exposure to these fields for low socioeconomic minorities then becomes a social justice issue. A mixed methods approach was applied which included surveys and interviews of junior students currently in an experiential careers program with a STEM emphasis. Composites and subscales were created and checked for internal reliability and consistency. Interview responses were recorded and coded based on theories of occupational identity and emergent themes. Findings suggest that most students within the experiential careers program exhibited high levels of occupational identity. The experiential learning model works well to support continuous learning and the identity development of students from low socioeconomic backgrounds.

Improving science, technology, engineering, and mathematics (STEM) education has become a national priority and the call to modernize secondary science has been heard. A Physics First (PF) program with the curriculum sequence of physics, chemistry, and biology (PCB) driven by inquiry- and project-based learning offers a viable alternative to the traditional curricular sequence (BCP) and methods of teaching, but requires more empirical evidence. This study determined impact of a PF program (PF-PCB) on math achievement (SAT math scores) after the first two cohorts of students completed the PF-PCB program at Matteo Ricci High School (MRHS) and provided more quantitative data to inform the PF debate and advance secondary science education. Statistical analysis (ANCOVA) determined the influence of covariates and revealed that PF-PCB program had a significant (p < .05) impact on SAT math scores in the second cohort at MRHS. Statistically adjusted, the SAT math means for PF students were 21.4 points higher than their non-PF counterparts when controlling for prior math achievement (HSTP math), socioeconomic status (SES), and ethnicity/race.

The purpose of this study was to explore and analyze which fifth-grade teacher inputs were the most important predictors of future outcomes of eighth-grade math students. This quantitative study looked at mathematical achievement through the lens of an education production function. The three inputs that were analyzed were fifth-grade teachers’ background; perception of professional development; and instructional practices and the relationship of those practices to achievement in eighth-grade math. In order to find the relationship between the above variables and student achievement, descriptive statistics, multiple correlations, and multi-variable regression analysis were conducted to examine which predictors had a stronger relationship between eighth-grade math outcomes than others. Taken as a whole, fifth-grade teacher math inputs in this study seemed to explain a small part of the variance regarding eighth-grade math achievement. As a whole, the more frequently students wrote and spoke about math in fifth grade as well as used math tools effectively, the better the outcome in eighth grade.

Science instruction in the early years of a student’s education career is essential to a student successfully continuing science in their secondary and postsecondary careers. However, the amount of high-quality science instruction students receive at the elementary level has been steadily declining for two decades, resulting in an inequitable imbalance in those who pursue STEM careers, a lack of critical science literacy in the U.S. populace, and a shortage of qualified employees entering the U.S. economy. Much of the lack of science instruction can be traced to decreased training of teachers to teach science during elementary credentialing programs or the complete absence of said training. This qualitative study sought to understand, through multiple-case study analysis, what makes one university “successful” at teaching science methods to their pre-service teachers and what makes another “unsuccessful.” Through interviews, observations, and an online document review, the author found that pre-service teachers entering the elementary school classroom need to feel they have the content knowledge necessary to teach science, feel they can overcome and work within barriers to high-quality science instruction in the K-12 system, and feel ready and prepared to teach science by their chosen Teacher Preparation Program.

As students transition into middle school science courses, their interest and engagement in the subject declines. This decline is most significant among girls, particularly for topics in physical science. While several factors have been identified that contribute to the decline, one area that is emerging as a new way to help improve girls' view of science is the use of educational video games to improve engagement and interest in science content, particularly as video games have been steadily rising in popularity with girls. This study used Cultural Historical Activity Theory to understand how middle school girls engage with an educational video game designed to teach physical science concepts and how game design influences engagement. Ten participants played three games. Games were chosen to reflect diverse designs and mechanics. Participants were observed and audio recorded during the play and debriefed after the play. Games designs like open exploration, an in-game story, and gradually increasing challenges connected to content all supported engagement. Game design that used low cognitive demand, repetitive tasks, and increasing difficulty connected to game mechanics discouraged engagement. The enjoyment of the game itself increased interest in physical science topics. By better understanding the perspective of female students, these findings guide educators in selecting educative games for middle school girls and support game designers to better engage girls in the games and interest them in science.
