Keywords: child development, computer research, early child development (birth to age four), Health, High School, project, rubric
School Subject(s): Health
As a ninth grade health teacher, I have realized that some students are very weak in their ability to organize information, set up a method to approach a problem or question and then record their results or summarize their ideas in a way that is clear and concise. This has been more apparent with the low achieving and special education students. They often are not able to think about what will happen next or why something happened. Another reason may lie in the fact that for these students, they are not highly invested in learning and not motivated to think in an organized manner. To increase motivation, this unit focuses on a topic of considerable interest for many of the students – early childhood development.
The elementary science curriculum introduces the scientific method, a systematic method of approach to inquiry, and this topic is revisited in the ninth grade biology and science classes. (1)The skills of setting up a method to approach a problem or situation, to gather information, organize the information or data and to draw a conclusion from the data or evidence are components of the scientific process. This unit will focus on three skills that are related to scientific practices. They are 1) Asking Questions. Students will develop the skills to ask probing questions that will help identify the premises of the topic. 2) Planning and Carrying Out Investigations: Students will decide what data or information that they need to gather and how they will go about doing it. They will develop a scope of information that they think is important to child development. In addition, they will expand their scope to include research on subcategories for each developmental stage. 3) Analyze and Interpret Data. Students will look for patterns and overlapping characteristics in each stage of development, focusing on the changing needs of a child from birth to age 4.

The Scientific Process is a method that is easily transferred from science and science experiments to other areas of the curriculum, in this case, Health, particularly, Child Development. It has been my experience, that there are a number of students that do not know how to implement the components of the scientific method to other areas of the curriculum, and in some cases to their personal lives. This unit will focus on the steps of the scientific method. The students will brainstorm what they think should be included in the study of child development from birth through age four. Students will be asked to draw on their personal experience with children in these age groups. They will be asked to organize the responses and categorize them when applicable. Students will develop a time line of growth and development and relate activities and equipment or toys that are appropriate to the age or stage of development. This is necessary because many students are responsible for younger siblings, relatives and their own children. I chose this particular area of growth and development because I have students that are either pregnant or are parents. They are very eager to discuss areas of pregnancy and child development because it is relevant. We are seeing teenagers, fourteen years of age and even younger, having children and being responsible for their well-being. Granted, many of the teen mothers live with their families and have the support and guidance of their family, especially the teen parent’s mother and grandmother. Even with this support, the teen mother is responsible for caring for her child. It is up to her to care for and nurture her child. She is responsible for making many decisions that will affect her child. These decisions cover the areas of clothing, food, toys and activities that need to be appropriate for the child at each stage of development. As an adult mother, we have the intuition that comes from experience, knowledge and exposure to know for the most part what is the appropriate: what food to feed a child at a given age, what precautions to take when it comes to safety, the size of toy pieces etc. Teen moms often do not have the life experiences or knowledge to make these choices or decisions. There is also the influence of the lag in frontal lobe development of a teen’s brain, which can account for even older teens having a reduced ability to anticipate consequences and their ability for plan for possible safety concerns. Other components of the development of a child include social and emotional development. The dilemma a teen parent faces is that she is still growing socially and emotionally and in many cases does not recognize that this is as important as physical development. Often, the teen mom sees a temper tantrum as a time of unexpected and annoying crying, yelling or kicking without understanding the causes of the tantrum and how it possibly can be avoided. Ensuring that the child is not overly tired or frustrated often will eliminate the tantrum. Other areas of social and emotional development: recognizing familiar people, responding to facial expressions and learning how to show emotions are also occurring during a child’s first year. (2) One stage of development that students will study in this unit will cover the physical development from birth through age one. During this stage of development, the infant experiences a stage of rapid growth through approximately the fourth month. Weight is typically doubled from birth. Body length is growing by about one inch a month. By the end of the first year, it is not uncommon for body weight to be three times the birth weight and body length to continue to grow about one inch a month. With regards to weight, an infant will drop anywhere from 5 – 10% of its birth weight in the first week due mainly to a lose of water. It is during this time that the infant is no longer dependent on fluids and nourishment from its mother, and now is depending on receiving fluids/nourishment from being feed. The amount of fluid depends on the baby’s ability to suck and swallow, reflexes that are developed after birth. It is also during this time that you will see a change in the proportions of the infant’s body. At birth, the head of an infant is almost one-fourth or 25% of its length where at the age of one year, the head is only one-fifth or 20% of its length. Compare this to the size of head of an adult, which is approximately one-eighth or 12. 5% of its length (or height). The weight that is gained during the first year changes from fatty weight to muscle and bone weight. In the first several months, an infant’s weight gain is mostly fat. The fat supply is used for insulation and nourishment in case of illness or not being able to eat. (4) There is true validity in the statement that a child “grows like a weed”. Changes in motor skills also occur this time. The change from not being able to move to lifting the head and shoulders, turning over, sitting unassisted, scooting, crawling and in many cases, even walking unassisted. Along with this you will see reflexes appear and then when not needed, disappear. For example, the breathing reflex, which is necessary for survival, is present at birth and continues to develop and become stronger. Evidence of this development can be seen while observing a newborn’s breathing pattern. Initially, the breathing can be irregular with hiccups, sneezes and spitting up. These occur because the infant is trying to coordinate it’s breathing, sucking and swallowing which are needed for its intake of food. Other reflexes include motor reflexes such as the Babinski reflex, which is evident when you stroke the bottom of an infant’s foot. With this reflex, the toes spread out. You also will see a swimming reflex of the arms and legs moving when you hold an infant on its stomach horizontally. Another reflex that is very evident is the grasping reflex which develops over time from holding on until the infant loses interest to where the child is able to pick up small items using 2 fingers (pincher reflex). (4) The newborn has its first social encounter immediately after birth when the baby is given to its mother for the first time. This is not a new encounter, but a continuation of the intimate relation that was building through out the pregnancy. Communication by the infant is initially by crying or making noises. Communication continues through visual contact, making noises (dahdah, goo-goo), smiling, and laughing and then first words. (6) Between the age of twelve and twenty-four months, the child is still experiencing height and weight gain that is still considered rapid, but not as much as during the first twelve months. Walking is more coordinated and the child will learn to jump, run and climb usually by twenty-four months. The child is able to play with objects, can sort objects into categories, has longer attention span, engages in make believe, and is getting better at recalling memory for people, places and objects. Language skills begin, and by age twenty-four months the child is combining two words. Emotional and social growth includes playing with adults, siblings and peers. At approximately thirteen to eighteen months the emergence of “me” is apparent, and the child recognizing himself in the mirror, pictures and videos. This is the time where the child is beginning to be able to follow directions. From nineteen to twenty-four months the emotions related to feelings: shame, embarrassment, guilt and pride are starting to emerge as well as the vocabulary to match the emotions. The child starts to use its own name. (5) The ages of three and four (thirty-six to forty-eight months) has the child walking upstairs alternating feet and down stairs leading with one foot. The child is able to jump up off the floor using arms and can hop on the same foot several times. You will also see the child throwing a ball and can catch a ball or object by catching and holding object to its chest. This is the age where the child is able to ride a tricycle. (5) As adults, we are very open and inquisitive to learning the latest trends in parenting. We read books and articles on what to expect during pregnancy, childbirth and for each stage of our child’s development. There are many books and magazines available keep us informed. Many teen moms are still pre-occupied with being a teen and don’t take the time, nor do they really have the interest in learning more about a baby’s development. The Parent Magazine has a wealth of information for all aspects of parenting, from pregnancy information to suggestions on games to play with your one year old. This is a resource that can be found on line as well as in print. New moms to be and new mom’s find this to be a great source of information and practical ideas to help with parenting. (3)
Objectives of this unit: a typical natural science curriculum. area of child development organize the information that they have, to identify what they need to research and then develop a plan of attack. questions and where appropriate, revise their questions based on data collected. their “flour” baby.
Strategies that will be implemented in this unit include small group/cooperative learning, accessing prior knowledge, sharing out, use of technology for research as well as graphic organizers (KWL chart, T chart, contrast and comparison). Situations You Might Encounter Possible difficulties in this unit might include motivating students to think in a scientific manner, especially when the subject is health and not a science course. It may be difficult to focus on the organization of information because of the different subcategories of development (i.e. physical, social, cognitive and motor skills) and the possibilities of the overlapping of these, skills and activities. The students will learn that there is no definite skill that is acquired at a specific time or age. Another difficulty may arise; especially if your students do not have a strong understanding of the importance to organizational skills is why the organization is important, and then how to organize facts. Many students that I have had, do well if you provide detailed instructions, or work sheets that are created in an organized method, but asking the student to create an agenda of what they are going to research and then have them organize their information has been a problem. This is a skill that is necessary for success in everyday living. In this unit, students will have the opportunity to work in small groups and brainstorm ideas and ways to approach the topic. Sharing out to the whole group will give students the opportunity to hear other suggestions and ideas as well as developing their communication and public speaking skills. This will broaden their resources so that they can determine what will work best for them. Students will also be given a detailed rubric to guide their work. This rubric will be used for both formative and summative assessments. The rubric will guide the formative assessments that will not be graded. Rather, teacher/student discussions should be held throughout the unit. This will allow the student to see where he/she has made progress, met or surpassed expectations and what areas still need to be developed. The rubric is set up with expectations ranging from 4 to 1, with 4 being advanced and 1 label as “try again”. This gives the student the opportunity to revisit the areas that he/she was not able to complete at a higher degree of proficiency. Use of computers for research requires serious monitoring, as students will drift off to unrelated sites. Providing a list of sites that would be acceptable to use will reduce the time spent surfing and going to other sites such as twitter, face book and you tube. As a fall back resource, having a supply of baby and parenting magazines and books and toy and clothing catalogs. This will give students access to the same information when computers are being misused.
This unit will contain five lessons that will encompass the subject area of child development from birth to age 4. The activities will include research using the computer, gathering observational data from either younger siblings, relatives or in some case, the student’s own child. Other activities will include word searches, games and projects. Lesson One: Introduction of the components of the Scientific Process and how it will be used in the unit on Child Development. Focus will be on identifying the components of developmental stages from birth through age three. Objective: Students will identify the following scientific skills: asking questions, planning and carrying out investigations (research) and analyzing and interpreting data. Objective: Students will be able to use the scientific skill of developing questions that will help them understand the growth and development of a child, ages birth to age four. To prepare for the lesson (Do Now) the students will list three characteristics of an infant birth to three months, three to six months, six to twelve months, one-2 year old, two-3 year old and three-four year old. Activities: 1). Teacher has chart paper on wall labeled INTU (I Need To Understand). Teacher describes the unit of study for class: studying the growth and development of a childbirth to age four. Students are given a moment to think about the topic so that they can provide one area that they need to understand at the end of the unit. Teacher writes down each student’s INTU on the chart paper. (When INTU is identified by student’s name, teacher can refer back to that point as the subject area is covered. A great way to reinforce what is relevant to each student.) In order to stimulate questions, Teacher will discuss the purpose of developing questions and the role questions play in the scientific process. As students pose their question for the INTU chart, discussion between Teacher and students is directed toward the “question”. Is the question going to provoke deeper thought or can it be answered with little to no research? If we study or research this “question” will it lead to other questions, or stop with the facts that we find? This type of class discussion will help the students understand the rationale of developing higher order thought questions and how it can expand the possibility of more questions. 2) Chart paper is hung around the room and Marked “Birth to three months”, “Three – six months”, Six months – twelve months,” “One Year-Two Years” “Two Years-Three Years” and “Three Years-Four Years”. Students will do a “Gallery Walk” and write down what type of development they would expect to see at that age. These charts will be used in another lesson when students are researching activities, toys and other necessities that are relevant to that particular age group. Teacher should anticipate possible confusion when the skill can be learned or acquired at different age groups. A few of these skills can include: learning to walk, talking, temper tantrums, etc. This can provide opportunity for additional research for proficient and advanced students, or is an opportunity to discuss the reasons for the overlapping of skills in different age groups. Supplies: Chart paper, markers, rubric for the unit. Lesson Two: Developing a bank of questions that will guide their research and help the students make predictions. Students work in small groups, with each group focusing on a particular age/developmental stage. They will decide as a group what they think they will discover about that age group: the developmental milestones both physical and mental, clothing/food requirements, stimulators (toys and activities), required equipment (cribs, car seat, and clothing). This lesson can spread over two days depending on the resources that are available for information: websites, magazines, newspaper and store advertisements. Objective: Students will be able to develop their own questions that relate to the needs of their targeted age group. To prepare for the lesson (Do Now): What is the purpose of asking questions when you are going to search for information? What type of questions should you be asking, as you get ready to search for information? What are predictions? Activities: An extension activity: Provide a budget amount and have students make a plan for buying what is essential for a child in the age group they are studying. Supplies needed: computers, magazines, newspapers, advertisements, and notecards. Lesson Three: Organization skills: Research using the computer to find information on child development, stages and ages of each step and characteristics and milestones and needs of each stage. Objective: Students will develop strong organizational skills by categorizing their data for their age group. Students will learn how to use notecards as a method of recording data and sorting into categories or groups. Objective: Students will be able to analyze the differences of the uses of various graphic organizers so they can choose or develop one that will allow them to effectively organize their research findings. Students will use graphic organizers to record their findings. Teacher will provide examples of several types of graphic organizers (www.educationoasis.com/curriculum/GO/compare_contrast.htm,) and discuss the purpose of each one. Students should be encouraged to develop their own organizers. Encourage students to explain why they choose the graphic organizer that they did. Questions to ask students: After choosing their graphic organizer, did they need to modify it as they continued to gather information and if they did, why? Did you find that the graphic organizer helped you gather information? Why or why not? Do you think that there may have been a different way to organize your data? If so, describe it. Compare your process of gathering information on baby related items to that of a scientist who is gathering data for their experiment. Activities: Supplies: Variety of graphic organizers, colored pens, pencils (for students to use to help organize their data). Lesson Four: Data: Gathering data from observation. Students will observe siblings and relatives, to see if the children exhibit the developmental milestones, play with the appropriate toys/activities, what they eat, etc. They will then compare their observations to the information that they found in their research. Objective: Students will be able to collect data from observations. They will observe, collect, record and interpret data. To prepare for lesson (Do Now): How do you observe children? What will you be looking for? How will you record your information? Activity: Lesson Five Objective: Students will be able to simulate the experience of parenting by caring for a “flour” baby for two days. To prepare for the lesson (Do Now): Scope of the Project: Students will care for a “flour baby” for two days. Students will be instructed to carry their “baby” with them at all times, or arrange for a baby sitter to care for the “flour baby” when they can’t. They will record their activities as a caregiver for the two day period. Students will be given 2# bags of flour to use as their “baby”. Time can be given to design clothes, blanket and baby carriers in class. Other options can include using doll babies. Provide students with timers to set every 4 fours to simulate time frame for feeding and changing diapers. (If your have a budget to purchase “Baby Think It Over”, the experience is definitively very real. This baby operates just as a real baby does. There is a tape that tracks the time taken to change diaper, feed or just pick up the baby to try to stop the crying. Tape also records what would be considered abusive care: letting head drop, mistreating child, etc.) Lesson extension: While discussing the different developmental and activity stages, activate a floor-cleaning robot to roam around the room to simulate the activity of a toddler. Another suggestion, if you are permitted to bring in a pet dog, gives the dog free reign to roam around and interact with the students. The purpose is to imitate the activity level and constant changing of direction and attention that a toddler has. Students will observe how the robot or pet needs to be watched constantly because you don’t know what a child will do or where the robot or pet will wander off too. Lesson Six: Conclusions concerning their questions/Accepting or rejecting their predictions: Students will come to conclusions that will either support or reject their predictions on their expectations of a particular developmental stage and summarize their answers to their questions. Objective: To prepare for the lesson (Do Now): Why would a scientist decide not to accept their original predictions? What is the purpose of developing predictions? What do we use to form our conclusions? What conclusion did you come to regarding the developmental stage that you researched? Did your conclusion support your predictions? Why or why not? Activities Lesson Seven: Students will create posters that support the data and information that they have gathered. Each group will share out their questions, predictions and findings. Posters will be displayed in the classroom showing the progression of development. Objective: Students will be able to analyze the information that they have collected and present their finds in posters. Students will be able to share their findings about each age group. To prepare for lesson (Do Now): What age group do you think will be the easiest to parent? Why? What activities or toys would you recommend for this age group? Do you feel your recommendations are needed for child to successfully mature at this stage of development?
