Regression-based Forecast Combination Methods
Least squares combinations (Granger & Ramanathan, 1984) are an important development in the forecast combination literature. However, ordinary least squares methods often perform poorly in real application due to the variability of coefficient/weight estimations. In this work, on one hand, we propose sequential subset selections to reduce the variability during combinations. On the other hand, we propose a novel method to simultaneously stabilize and shrink the coefficient/weights estimates. The proposed methods can be applied to various combination methods to improve prediction as long as their weights are determined based on ordinary least squares.forecast combinations, least squares, sequential selection, stabilization, shrinkage
ICAP Taxonomy of Modes of Cognitive Engagement: A Learner-Centered Theory Focusing on Observable Engagement Behaviors
Historically, there have been a number of impactful education theories that used the taxonomy as a classification device, such as the Bloom taxonomy of educational objectives and Gagne taxonomy of learning outcomes. The Bloom taxonomy of educational objectives was developed in the 1950s by the U.S. Committee of College and University Examiners under the leadership of Dr. Benjamin Bloom, which categorizes educational objectives into three domains: cognitive, affective, and psychomotor. Among them, the cognitive domain (the main concern of their research) contains six major classes: knowledge, comprehension, application, analysis, synthesis, evaluation. They are arranged in a hierarchical order with the objectives in one class built on the behaviors found in the preceding classes. Its primary purpose is to provide classification of goals of the educational system for all teachers, administrators, professional specialists, and research workers who deal with curricular and evaluation problems (Committee of College and University Examiners, 1956). Gagne’s theory approaches learning from the viewpoint of the instruction. Under his taxonomy, the five categories of learning outcomes are verbal information, intellectual skills, cognitive strategies, motor skills, and attitudes, each of which requires necessary conditions to achieve and corresponds to specific principles of instructional events (Gagne, 1984)
Educational Justice: The Cornerstone of Modern Society
Educational equity, a key feature of modernized society, is the application of fundamental values of modern culture in education, such as freedom, equality, justice, and human rights (Cole, 2022). It is also a product of education modernization, as well as an essential element of the new era’s education
Parent Time Input in Teenager Education Matters More Than Shadow Education
In recent years, shadow education—paid private supplementary tutoring providing additional educational assistance for students who are preparing for a variety of examinations—has become one of the fastest growing industries in a number of countries around the world, causing concern among governments and education policymakers, who believe that shadow education exacerbates the financial burden on poor families and exacerbates education inequality (Yu & Zhang, 2022)
Flipped Learning Model: An Effective Approach to Primary School STEM Education
As early as 1986, the US National Science Board published Undergraduate Science, Mathematics, and Engineering Education, which is regarded as the initiation of STEM education (NSB, 1986). In October 2005, the National Academy of Science, National Academy of Engineering, Institute of Medicine, and National Research Center jointly submitted to the Congress of the United States Rising Above the Gathering Storm: Energizing and Employing America for a Brighter Economic Future, a report that put forward relevant recommendations to promote STEM education (Bybee, 2010). In October 2007, the US National Science Board issued A National Action Plan for Addressing the Critical Needs of the US Science, Technology, Engineering, and Mathematics Education System, proposing to expand STEM education from colleges to primary and secondary schools (NSB, 2007). In 2009, former President of the United States, Barack Obama, emphasized the need for the nation to prioritize the development of STEM education. Since then, the US federal government has heavily invested in STEM education research across all levels, from kindergarten through higher education. Educational communities in other countries have also begun researching and implementing STEM education practices. Numerous studies and extensive practice have demonstrated the potential of STEM education in promoting students’ cognitive development, enhancing their critical thinking, problem-solving, and creativity skills, as well as improving their emotional and spiritual well-being
How to Help Special Education Students?
According to UNICEF’s report, there are approximately 240 million disabled children in the world. They are typically in a disadvantaged position in terms of health, education, and safety, compared with their normal peers (UNICEF, 2021). By the end of 2018, there were 1045038 registered disabled kids aged 0-14 in China, accounting for roughly 3% of the total population with impairments (Chen, 2020). Such a huge number involves millions of families, who deserve the concern and support of the whole society
The Hope of Positive Behavior Interventions and the School Climate
Numerous factors influence educational success. Students’ learning performance and overall development are greatly influenced by their school environment. The term “school climate” refers to how instructors and students perceive the general atmosphere of the school based on their long-term interactions with it. It is directly tied to staff and student morale as well as their satisfaction with the school. As per the study by Pan et al. (2001), the psychological climate of the classroom is crucial in fostering students’ intellectual and physical development as well as personality development. The level of students’ mental health increases with an improved school climate. According to Zhou et al. (2021), the school environment can considerably increase students’ motivation to learn and their level of self-awareness and self-control. High expectations for behavior and a well-organized classroom can give children a safe place to learn in which they can cultivate good study habits and self-control, which will have a long-term effect on their overall development
A Learner-Centered Teaching Model
A teaching model is a plan or pattern that can be used to shape curriculum, to design teaching materials, and to guide instruction in the classroom and other settings. It is often developed based on specific educational philosophies and teaching theories, providing stable structures and procedures for teaching activities. Teaching models can be illustrations of instructional theories or generalizations of teaching experiences, allowing educational researchers to apply their ideas and concepts to practice, and practitioners to generalize about their instructional experiments and experience (Joyce & Weil, 1996). With the help of teaching models, educators can optimize their teaching methods and promote better learning outcomes for their students
