Integrating elements into a new structure through generating, planning, or producing is essential in higher-order thinking Bloom's Taxonomy categorizes critical thinking skills into knowledge, comprehension, application, analysis, synthesis, and evaluation, with the last three considered higher-order thinking skills The new taxonomy emphasizes the abilities to analyze, evaluate, and create as upper-level skills in the cognitive domain Therefore, critical and creative thinking are specific types of higher-order thinking skills that contrast with lower-order skills of understanding and remembering These skills are vital for university life and future careers, making it crucial for students to develop both gradually over time Educators should apply Bloom's classification as guidance to enhance the progression of students' thinking and nurture these higher-order thinking skills from early school years.

In 2015, the University of Education emphasized the importance of developing higher-order thinking skills among students These skills are crucial for enhancing critical thinking and problem-solving abilities, which are essential in today's complex world Educators should focus on teaching these skills in the classroom to prepare students for future challenges The rationale behind this approach aligns with the objectives of a master's thesis, highlighting the significant benefits that higher-order thinking skills provide for students' academic and personal growth.

Higher-order thinking processes enhance long-term memory retention compared to lower-order thinking For instance, a student who understands the derivation of a formula will retain that knowledge longer than one who merely memorizes it Additionally, students with deeper conceptual understanding are better equipped to apply knowledge in new contexts, making this a crucial benefit of higher-order thinking Knowledge gained through these processes is also more transferable, enabling students to solve new problems effectively Unfortunately, many educators overlook the importance of higher-order thinking skills, often focusing on lower-order skills that are easier to teach and assess This emphasis on lower-order skills may stem from their simplicity, as they are generally easier to understand, teach, test, and learn.

The sixth level in Bloom's revised Taxonomy – creating – represents the highest level of thinking according to Anderson's arrangement This level involves synthesizing elements into a pattern that has not existed before, making it the most challenging skill for teachers and students to achieve To succeed at this level, students must be able to synthesize their thinking and make predictions based on knowledge For students to attain this skill, they should begin practicing it from primary school Specifically, by the time students reach high school years, the majority of class assessment questions and discussions greatly enhance their ability to develop creative thinking skills.

The importance of creativity in education and life is paramount This section will discuss creative thinking skills and how to cultivate these skills for future purposes.

The importance of creativity has significantly increased in recent years, with various perspectives and approaches emerging in its study A substantial amount of management literature has focused on enhancing creativity in workplaces and educational settings to adapt to changing environments By 1999, researchers like Sternberg explored the origins of creativity, suggesting that many people believe creativity is not easily studied scientifically due to its spiritual nature However, pragmatic approaches to creativity have primarily concentrated on developing techniques to promote creative thinking within organizations Unfortunately, Sternberg indicates that these practical approaches only mention enhancing creativity without providing a clear understanding of its characteristics.

On the other hand, Stegner also refers to psychometric approaches to creativity These methods have primarily focused on developing tests to measure creativity Plucker and Genzulli (1999) differentiate four areas where psychometric methods have been applied in creativity research: creative process, personality and behavioral correlates, characteristics of creative products, and attributes of creative fostering environments The psychometric approach will be discussed in more detail later.

In 2015, the University of Education presented a thesis on the concept of creativity, which is defined by experts as the ability to engage in the creation of something new and useful This understanding emphasizes the importance of innovative thinking in academic and professional contexts.

Creativity involves selecting relevant aspects of a problem and integrating pieces into a coherent system that connects new information with what a person already knows Essentially, it encompasses a series of decision-making choices between two or more competing alternatives, each having several pros and cons associated with it.

Creativity is a habit that can be either encouraged or discouraged To foster creativity, individuals should promote creative habits and avoid treating creativity as a negative trait Strengthening suggests that creativity is not limited to the gifted; rather, it is a skill that anyone can develop His investment theory of creativity posits that anyone can be creative if they are willing to invest the necessary time and effort into the creative process This investment requires focus on six key areas to truly realize creativity.

Sƚeгпьeгǥ has proposed an investment theory of creativity to understand the nature of creativity According to this theory, creative individuals are those who are willing and able to "buy low and sell high" in the realm of ideas Creativity requires a confluence of six distinct but interrelated resources: intellectual abilities, knowledge, styles of thinking, personality, motivation, and environment Although the levels of these resources can vary among individuals, the decision to utilize them often reflects deeper individual differences.

The influence of these three abilities is crucial Analytical ability, when applied alongside the other two, leads to powerful critical thinking, though it does not inherently foster creativity Synthetical ability, in conjunction with the other two, generates new ideas that are not constrained by the stringent requirements needed to implement them Furthermore, practical-contextual ability, when combined with the other two, facilitates the transmission of ideas not merely because they are good, but because they have been effectively and compellingly presented To be creative, one must first generate new ideas, analyze them, and then communicate these ideas to others.

Knowledge about a field is essential for advancing it, but it can also lead to a closed mindset, preventing individuals from moving beyond their past experiences Therefore, one must balance utilizing past knowledge while avoiding the trap of letting it hinder future growth.

Thinking styles are essential for utilizing one's skills effectively They represent decisions on how to apply available skills Among these styles, a legislative style is particularly important for fostering creativity, as it encourages thinking in new ways This preference should be distinguished from the ability to think creatively; some individuals may prefer to think along new lines but struggle with effective thinking Additionally, being a major creative thinker requires the ability to think both globally and locally, recognizing which questions are important and which are not Research indicates that legislative individuals tend to be better students than their less legislative counterparts, especially in schools that value creativity Conversely, if schools do not value or devalue creativity, students may perform worse Students also tend to receive higher grades from teachers whose thinking styles align with their own Numerous studies have supported the significance of certain personal attributes for creative functioning, including the willingness to overcome obstacles, take sensible risks, tolerate ambiguity, and exhibit self-efficacy Specifically, being willing to sell low and buy high means defining the crowd, as one must be prepared to stand up to conventions if they wish to think creatively It is important to note that none of these attributes are fixed; individuals can choose to overcome obstacles, take sensible risks, and so forth.

Intrinsic task-focused motivation is essential for creativity Research has shown the importance of such motivation for creative work, indicating that individuals rarely engage in creative tasks unless they genuinely love what they are doing and are focused on the task at hand.

Creative thinking requires access to all necessary resources, but without some form of environmental support, such as a forum for proposing ideas, the inherent creativity within a person may never be fully expressed.

Different cultures support creativity differently and may have varying perceptions of what constitutes creativity It is essential to consider the environment when assessing creativity The influence of components emphasizes that creativity involves more than just a simple sum of a person's level on each component There may be thresholds for some components, such as knowledge, below which creativity is not possible, regardless of the levels of other components Additionally, partial compensation may occur, where strength in one component, like motivation, counteracts a weakness in another, such as the environment Interactions between components, such as intelligence and motivation, can also enhance creativity when both components are at high levels Creative ideas are both novel and valuable, and understanding creativity requires considering the broader context From an investment perspective, a creative person presents a unique idea and then attempts to convince others of its value, which increases the perceived value of the idea.

The investment in creativity involves sharing ideas with others and transitioning to new concepts People generally seek validation for their ideas, but immediate universal applause often indicates a lack of originality.

The abilities necessary for continual advancement and future achievements, as well as participation in and contribution to public and social life, stem from a synthesis of intelligence, creativity, and wisdom, collectively referred to as WIS (Wisdom, Intelligence, and Creativity) These abilities are governed by individual elements of the WIS model and their combinations Creativity is essential for the manifestation of initiative, imagination, and originality, which are crucial for scientific achievements and practical applications It plays a vital role in realizing the potential for organizational innovation and the development of creative solutions, achievements, and visionary spirit Therefore, creativity results from the simultaneous and joint functioning of all skills; without it, there is no promotion of good and useful ideas.

In education, the term "creativity" is often utilized Experts suggest that teachers encourage students to apply their creativity in project design or refer to a student's response as creative, without providing an explanation of what that entails.

The discipline of theories on creativity does not effectively frame the issue, as it often focuses on outstanding performances, thereby reinforcing the link between natural ability and creative achievements Research has shown that creative eminent individuals share several personal traits; however, this does not imply that creativity is confined to natural talent or ability Conversely, creative traits should be identified and studied to enable their duplication and teaching.

The first step towards effective learning and innovative teaching requires an understanding of the meaning of creativity in education and its implications This involves a threefold procedure: master's thesis, graduate thesis, and graduation thesis.

The definition of creativity emphasizes the process rather than the final product When we focus on the journey of creation and achievements, children are less likely to feel pressured by the outcome.

The 2015 Master's thesis from the University of Education emphasizes the importance of developing thinking skills in students, particularly when compared to adults It highlights that learning is a process that can be enhanced through creative approaches Furthermore, fostering creativity in learning necessitates adopting a process-oriented methodology This research area has been explored, particularly through the lens of various creative strategies.

Methods and techniques for creative thinking are designed to assist individuals in generating original ideas Utilizing these methods fosters attitudes and habits of mind that enable creativity Practicing creative thinking skills does not automatically translate into the transfer of such skills to other environments.

The crucial role of teachers is to select strategies that align smoothly with the developmental level of their students While many techniques, such as SAMR and brain-based learning, can be applied at almost any level, more sophisticated methods like project-based learning are best suited for students with advanced abstract thinking skills Only teachers can determine which ideas are most beneficial for their students, how they can be adapted, and which aspects of the students' lives provide the best opportunities for transfer Teachers must instruct students on general techniques that involve understanding how to use them, when to apply them, and under what circumstances they might be useful Students should practice these techniques in various contexts and discuss their applications.

Visualizing content can significantly enhance students' understanding Prior knowledge and careful guidance are essential for effectively increasing their comprehension through imagery, often referred to as guided imagery To maximize the effectiveness of this visualization technique, instructors should provide a structured, written or mental outline of the images to be processed As teachers guide students through the content, they should encourage them to sit in a comfortable position, typically with their eyes covered or closed Descriptions and suggestions must be presented slowly and clearly, allowing ample time for reflection and understanding.

Participants were asked to visualize aspects of a situation related to an animal This visualization process aimed to stimulate new ideas and perspectives Research indicated that undergraduate subjects were more successful in devising creative inventions when the task was somewhat restricted Those given a wide range of shapes to work with produced less creative responses compared to those who had a limited number of images and a specific category of objects to create from Interestingly, subjects also generated more original ideas when they created a pre-inventive form by combining images into an interesting and potentially useful shape before identifying the category of objects to be devised, rather than trying to sketch a form to fit a particular division.

Exploring research with variations on Finke's techniques would be fascinating for younger students They could be given specific geometric forms to visualize, control mentally, and use to create new ideas for inventions It may also be beneficial to consider if the notion of controlled tasks could be advantageous in teaching other creative thinking techniques.

Students engage in walking activities under a variety of circumstances, navigating through challenges such as juggling, hot sand, or going to school when their homework is incomplete Additionally, students play with a range of imaginative balls, experimenting with different types from a soft ball to a beach ball and a bowling ball.

Movement activities encompass various forms such as movement exercises, sensory-awareness exercises, pantomime, and other strength-building activities These movement exercises are primarily designed to help students gain control over their bodies and become aware of how they move Additionally, students can engage in activities that involve mimicking the movements and behaviors of animals.

Students can develop human characteristics based on certain aspects of the chosen animal Specifically, students feel compelled to be influenced by strings connected to various parts of their bodies.

Sensory awareness exercises are activities designed to boost students' awareness of their five senses Teachers may ask their students to eat imagined food, listen to imagined sounds, or feel imagined textures They may find that limiting one of the senses can enhance the others These activities can range from simple tasks to complex problem-solving scenarios More complex dramatic activities may require a planning phase as well as an acting stage.

Engaging discussions enhance the most creative dramatic activities Students can share their experiences, expressing how they felt, what worked, what didn’t, and what they might try next time These discussions clarify that creative drama is an active process They are interconnected activities that can bring insight into a variety of situations.

Techniques of creative thinking are designed to enhance students' diverse thinking or their ability to think of many different responses to a given situation The most prevalent meaning of diverse thinking includes fluency (thinking of many ideas), flexibility (thinking of different divisions or points of view), originality (thinking of unusual ideas), and elaboration (adding detail to improve ideas) The four crucial areas in this explanation indicate that fluency often serves as the basis for activities designed to improve diverse thinking Encouraging students to think of ideas that solve problems in different ways fosters flexibility Questions like “How can we build on this idea?” promote elaboration Thus, assisting students in understanding how diverse thinking fits into the whole of creative thinking is very important.

One of the easiest ways to introduce creativity in the classroom is by posing questions that, apart from knowledge of facts, require analytical and divergent thinking This approach builds self-efficacy, helps define and redefine problems, encourages idea generation, and allows for making mistakes Additionally, creativity can be stimulated by encouraging students to ask more questions during the acquisition of new scientific notions or when personal interests arise Students should also be encouraged to investigate the reasons behind their personal observations.

The Master's thesis at the University of Education in 2015 addresses solutions to various personal and social life situations and problems, emphasizing the importance of experimentation and critical thinking in safe environments.

When educators plan for teaching and learning that encourages creative thinking, they must engage in creative thinking themselves The essence of creative thinking involves questioning and challenging approaches to knowledge, along with a list of components that need to be present in a creative classroom where creative thinking takes place The creative model is viewed as a "creative ecosystem," consisting of interrelated elements.

Teachers play a crucial role in fostering creative education by promoting innovative thinking and encouraging students to express their unique ideas Educators must prepare the younger generation to think independently, enabling them to tackle new and challenging problems in our ever-changing world To be successful, individuals need to understand the process and synthesize information into unique ideas, purposes, and products In a creative education program, teachers should maintain an open-minded approach.

The Master’s thesis at the University of Education in 2015 emphasizes the importance of fostering creative solutions to problems and encourages students to engage in independent thinking It highlights the value of originality and acknowledges that multiple solutions may exist for any given issue.

Chemistry is a vital component of the school curriculum, with the potential to encourage students to think flexibly and enhance their problem-solving approaches This, in turn, contributes to the development of learners' creative capabilities The effectiveness of chemistry education in stimulating creativity relies heavily on the teaching methods employed.

I provide relative teaching plans, questions, and problem sets for experimental classes These include questions for homework assignments or discussions in small groups during class.

Using problem sets and quizzes designed to enhance problem-solving skills, ranging from easy to difficult levels, significantly impacts the development of creative thinking in writing assignments.

The experimental class consistently engages with creative questions and problems, such as imagining elements, predicting outcomes of exercises, and explaining relationships with reality in various ways Through these practices, students will develop their creative reflection and acquire valuable skills.

In the experimental class, students spend 10 to 15 minutes at the end of each lesson summarizing the content independently The class is divided into groups of four, with each group tasked to use creative methods such as mind mapping, storytelling, drawing, or picturing to remember and summarize the lesson This approach enhances the creative skills of learners, proving beneficial not only in chemistry but also in other subjects.

Standard deviation is a measure used to quantify the amount of variation or dispersion of a set of data values A standard deviation close to zero indicates that the data points tend to be very close to the mean of the set, while a high standard deviation suggests that the data points are spread out over a wider range of values.
