Fall Semester, First Year
14 Units TotalThis course is a survey of the history of the United States from Pre-Columbian Peoples to the end of Reconstruction. Topics include contact and settlement of America, the movement toward independence, the formation of a new nation and Constitution, westward expansion and manifest destiny, the causes and consequences of the Civil War, and Reconstruction. This course satisfies the CSU requirement for US History (US-1). This course may be offered in a distance education format.
An introductory course in statistics designed to show the role of modern statistical methods in the process of decision making. Concepts are introduced by example rather than by rigorous mathematical theory. The following topics will be covered: measures of central tendency and dispersion, regression and correlation, probability, sampling distributions including the normal, t, and chi-square, statistical inference using confidence intervals and hypotheses testing. This course may be offered in a distance education format.
Earth is a dynamic planet, changing in response to natural processes within the atmosphere, geosphere, hydrosphere and biosphere. Modern science is now viewing the Earth system in its entirety, the sum of its parts, in an effort to understand how processes in one sphere impact those in another. This course stresses the inter-relationships of these systems and reviews natural cycles and positive and negative feedback pathways that operate over various time scales to affect global environmental change. The impact of civilization on the Earth system is also analyzed as the course considers pollution, over population, global warming, deforestation, desertification, resource depletion, and biologic extinctions along with solutions developed within sustainable concepts and practices. This course may be offered in a distance education format.
Spring Semester, First Year
17 Units TotalThis course is an introduction to the process of human communication with emphasis on public speaking. Subjects covered are audience analysis, choosing speech topics, finding and using supporting materials, arranging and outlining related points, essentials of speech delivery and evaluation. College level writing skills will be expected on all papers, outlines and short essays.
A three day, two-night field trip to Patrick's Point State Park to familiarize students with the organisms and ecological interactions occurring in the various plant communities and intertidal zones. One pre-trip introductory lecture will be held.
An introduction to the physical processes that drive Earth as a dynamic planet. Both internal and external processes are considered as well as their inter-relationships. Discussion in the course will include Earth?s internal structure, plate tectonics, minerals and rocks and their origins, surface processes, geologic structures such as faulting and folding, metamorphism, sedimentation, soil formation, geologic time including radiometric methods, geologic hazards such as earthquakes, volcanism, mass wasting, flooding, and the vital nature of Earth materials to society. Laboratory activities will focus on the application of classroom concepts and will include mineral and rock identification, geologic structures, topographic and geologic map use, use of remote imagery, recognition of landforms, geologic time, seismology, and volcanism. Lecture and laboratory will consider geologically produced and influenced natural resources, their exploitation, and concepts centered about sustainable uses. The lecture portion of this course may be offered in a distance education format.
This course accompanies ESCI 37 and represents laboratory and field activities associated with the northern California coast, inclusive of a three-day, overnight field trip along this stretch of coast. This course supports the goal of understanding the geology and geologic history of the north coast, as well as oceanographic and climatologic qualities as they converge to define habitats. Coastal sites demonstrate these relationships, and lab sessions prior to the trip will focus on the application of ESCI 37 concepts. Field exercises will be conducted at various stops.
Fall Semester, Second Year
15 Units TotalThis course is a survey of past life presented through geologic and biologic investigation. This course is interdisciplinary in nature and provides geologic background and evidence for the origination and evolution of life. Associated methodologies and concepts presented include geologic time and its measure, chemical and organic evolution, controls on evolution, cladistic analysis, ancient ecologic reconstruction, mass extinction and adaptive radiation, fossilization, and ancient geographic distributions of flora and fauna. Anatomical innovations that define major classes of organisms are traced through ancestor-descendant relationships. Laboratory exercises include processes of fossilization, fossil recognition, cladistic analysis, genetics, stratigraphy, reconstruction of ancient biologic communities, ancient geographic reconstruction through fossil information, functional morphology, mass extinction and adaptive radiation in the fossil record. The lecture portion of this course may be offered in a distance education format.
An introduction to the geologic processes that have shaped the northern Sierras into a geologically diverse setting. The course will culminate with a three-day field trip through the northern Sierras. Lecture meetings will present basic concepts in geology as well as topics specific to the northern Sierras such as continental growth, multiple mountain building and landscape development, glaciation and related geomorphology, and "mother-lode" economic geology. Field trip exercises will also be conducted at various stops. The lecture portion of this course may be offered in a distance learning format.
This course accompanies ESCI 32 and represents laboratory and field activities associated with the northern Sierras, inclusive of a three-day, overnight field trip across this region. This course supports the goal of understanding the geology and geologic history of the northern section of the Sierra Nevada mountains, as well as economic and climatologic qualities as they converge to produce important needed resources and Alpine, foothill and even wetland and desert habitats. Field sites demonstrate these relationships, and lab sessions prior to the trip will focus on the application of ESCI 32 concepts in preparation for the field trip. Field exercises will be conducted at various stops.
Spring Semester, Second Year
15 Units TotalThis course takes an interdisciplinary approach to the study of race and ethnicity in the United States. It examines social justice movements in relation to ethnic and racial groups in the United States to provide a basis for a better understanding of the socioeconomic, cultural, and political conditions among key social groups including, but not limited to, Native Americans, African Americans, Asian Americans, and Latina/o Americans. This course examines the systemic nature of racial/ethnic oppression through an examination of key concepts including racialization and ethnocentrism, with a specific focus on the persistence of white supremacy. Using an anti-racist framework, the course will examine historical and contemporary social movements dedicated to the decolonization of social institutions, resistance, and social justice. This course may be offered in a distance education format.
An introduction to United States and California government and politics, including their constitutions, political institutions and processes, and political actors. Examination of political behavior, political issues, and public policy. This course satisfies the CSU requirement in U.S. Constitution and California State and local government (US-2 and US-3). This course may be offered in a distance education format.
This course accompanies ESCI 35 and represents laboratory and field activities associated with Lassen Volcanic National Park, inclusive of a three-day overnight field trip within and around the park. This course supports the goal of understanding the geologic and climatologic history and modern ecologic character of the park through site and outcrop exposures as they demonstrate volcanic processes, volcanic and geothermal features, past glaciation and glacial features, slide hazards, faulting, and typical seasonality experienced by the park as it drives ecology. Field exercises will be conducted at various stops.
