Space exploration continues to expand humanity’s understanding of the universe. And, while Americans have widely favorable attitudes towards efforts to explore outer space, certain religious beliefs appear to be associated with more negative attitudes towards space exploration and the search for extraterrestrial life. The current study explored the role of religion and creationism on attitudes towards space exploration and the search for extraterrestrial life. Priming techniques were used to test whether increasing the accessibility of religious and creationist concepts led to more negative attitudes towards space exploration and beliefs about extraterrestrial life. Participants (N = 230) encountered an explicit prime of religion, creationism, or a control prior to completing a word fragment task and measures of attitudes towards space exploration and beliefs about extraterrestrial life. The results of Bayesian estimation and hypothesis testing did not support the prediction. However, exploratory analyses indicated very strong evidence of atheists having more positive attitudes towards space exploration and beliefs about extraterrestrial life than theists. These findings suggest that while priming religion and creationism did not appear to influence reported attitudes, attitudes towards space exploration and the search for extraterrestrial life may differ based on belief in god.

abstract: Affect is a domain of psychology that includes attitudes, emotions, interests, and values. My own affect influenced the choice of topics for my dissertation. After examining asteroid interiors and the Moon’s thermal evolution, I discuss the role of affect in online science education. I begin with asteroids, which are collections of smaller objects held together by gravity and possibly cohesion. These “rubble-pile” objects may experience the Brazil Nut Effect (BNE). When a collection of particles of similar densities, but of different sizes, is shaken, smaller particles will move parallel to the local gravity vector while larger objects will do the opposite. Thus, when asteroids are shaken by impacts, they may experience the BNE as possibly evidenced by large boulders seen on their surfaces. I found while the BNE is plausible on asteroids, it is confined to only the outer layers. The Moon, which formed with a Lunar Magma Ocean (LMO), is the next topic of this work. The LMO is due to the Moon forming rapidly after a giant impact between the proto-Earth and another planetary body. The first 80% of the LMO solidified rapidly at which point a floatation crust formed and slowed solidification of the remaining LMO. Impact bombardment during this cooling process, while an important component, has not been studied in detail. Impacts considered here are from debris generated during the formation of the Moon. I developed a thermal model that incorporates impacts and find that impacts may have either expedited or delayed LMO solidification. Finally, I return to affect to consider the differences in attitudes towards science between students enrolled in fully-online degree programs and those enrolled in traditional, in-person degree programs. I analyzed pre- and post-course survey data from the online astrobiology course Habitable Worlds. Unlike their traditional program counterparts, students enrolled in online programs started the course with better attitudes towards science and also further changed towards more positive attitudes during the course. Along with important conclusions in three research fields, this work aims to demonstrate the importance of affect in both scientific research and science education. / Dissertation/Thesis / Doctoral Dissertation Geological Sciences 2017

The purpose of the present study is to investigate the differences on gifted student&rsquo / s attitudes toward science and their preferred classroom climate during science classes based on gender and grade level. Two questionnaires, the Test of Science Related Attitudes (TOSRA) and the Individualized Classroom Environment Questionnaire (ICEQ), were used as survey tools in this study. A group of 163 gifted and talented students among four academic levels which are eighth grade, English prep class, ninth and eleventh grade were assigned to take part in this study. The data obtained from administration of measuring instrument were analyzed by using Two-Analyses of Variance (ANOVA). Result indicated that grade level of students had a significant effect on attitudes towards science. The study found, first, lower-grade students show more positive attitudes toward science than the students at higher-grade level. Secondly, there are significant differences were found among students in their perceptions of the science classroom environment based on their gender and grade level. Female students expected more personalization than male students, higher grade students preferred to have more independence and more differentiated classroom environment than lower grade students while they are learning.

Research has shown that interest in science often decreases in the middle-school grades for both boys and girls, but that more boys continue on the science track in high school and college, leading to males dominating the fields of science and engineering in the work place. The interpersonal interaction between teachers and students, as both individuals and as a group, comprises a large part of the classroom learning environment. Though these interactions last only a school year, they can influence student attitudes and achievement in the long term. Past research has suggested that a key factor in improving student achievement and attitudes is to create learning environments which emphasize characteristics that have been found to be linked empirically with achievement and attitudes. The purpose of this study was to use quantitative methods to validate a learning environment questionnaire (Questionnaire on Teacher Interaction, QTI), to investigate outcome-environment associations, and to compare male and female students in terms of their attitudes, classroom environment perceptions and achievement. An attitude scale, based on items from the Test of Science Related Attitudes (TOSRA), and a 48-item eight-scale version of the QTI were administered to 1228 science students in Grades 6, 7 and 8 at one middle school in South Florida. Student achievement was measured using the students’ quarterly (nine-week) science grade. / The results revealed satisfactory internal consistency reliability for the QTI, with alpha reliability coefficients ranging from 0.51 to 0.83 for different scales with the student as the unit of analysis and from 0.54 to 0.96 for class means. For the 10-item attitude scale, the alpha coefficient was above 0.80 for both the student and the class mean as the unit of analysis, demonstrating high internal consistency reliability. Overall, the results of the statistical analyses supported that the QTI questionnaire and the attitude scale are valid and reliable instruments for use with secondary science students in South Florida. A strong relationship was found between student outcomes (attitudes and achievement) and many of the eight QTI scales with either the individual or the class mean as the unit of analysis. For example, students’ attitudes towards science were more positive when teachers exhibited more leadership and understanding behaviors and science achievement was higher when teachers were friendlier and less uncertain. The use of MANOVA tentatively revealed gender differences in students’ perceptions of teacher interpersonal behavior, attitudes towards science, and science achievement. However, the differences between males and females were statistically significant only for the Helping/Friendly, Dissatisfied, and Admonishing scales of the QTI and for achievement. In general, relative to males, female students had more positive perceptions of teacher interpersonal behavior and higher academic achievement.

There has existed for many years a memory enhancement technique ("memory pegs") that although having dramatic demonstrable success in some individual cases has not been generally applied in education. The emergence of constructivist epistemology has emphasised the notion that learning occurs as a result of connecting new material with previously learnt concepts. There is, therefore, the implication that effective learning requires some previous knowledge upon which to attach new concepts - and thus realisation of the importance of learning with respect to acquiring factual information as a prerequisite to learning new processes and/or skills. This issue has focussed my attention on the need to ensure that the more physiological skills of accessing 'memory', both for learning and recall, are optimised for maximum learning. Further, there are some indications that the physiological skills of memory access (storage and retrieval) may respond favourably to training and 'exercise'. This study was designed to find out whether or not a repeated 'exercise' using a simple memory enhancement technique would lead to a determinable and statistically significant increase in overall performance in a range of cognitive skills (as indicated by science and mathematics examination results), whether learning such a technique would affect a student's attitudes towards science, whether there was a relationship between the amount of time spent practicing the technique and the degree of effect, and whether the memory technique did actually improve the ability to recall lists of objects.
