Distributed Instruction vs. Massed Instruction…… The Spacing Effect What It Is and Why It Should Matter to Itinerant Early Childhood Special Education Professionals

Consultation vs. One-to-One and Small Group Instruction in Itinerant ECSE Services This is the primary consideration in current IECSE practice. Which is the more efficient approach to teaching? The adoption of a consultation model as the primary mode of intervention in IECSE services must be based on efficiency of instruction vs. traditional patterns of practice
Rationale for Consultation / Coaching in IECSE Services If periodic or episodic intervention (usually minutes per week in traditional IECSE service delivery) is as efficient as distributed or spaced instruction (or practice), then there is no need to adopt a consultation model as the primary mode of intervention, however…… If distributed, or spaced instruction or practice, is a more efficient model of learning, then adoption of a consultation approach to IECSE intervention is warranted
Rationale for Consultation / Coaching in IECSE Services If consultation is to be considered as a preferred alternative to minute, one-to-one or teacher-directed small group instruction, then the research base related to efficiency of child learning must be examined
What is the Spacing Effect? The tendency for spaced (distributed) teaching to yield much better learning than massed teaching sessions Examples of Spaced Practice or Teaching In 1 day: Study 2 hours, break, study 2 hours, break Across days: Study on Mon, Tues, Wed Example of Massed Practice “Cramming”
What is Interstudy Interval (ISI)? The interval separating different study or practice episodes of the same materials In most studies are at least 2 study or practice episodes separated by an ISI Example: Study 2 hr, ½ hr break, Study 2 hr Means ISI = ½ hour
Research with Adults - 1 Donovan & Radosevich, 1999 Reviewed 63 studies involving acquisition of a skill or information with adults Results: Distributed practice was significantly superior to massed practice
Research with Adults - 2 Cepeda, Pashler, Vul, Wixted & Rohrer, 2006 Reviewed 317 studies of verbal memory tasks with children and adults Results: Spaced learning of items consistently showed benefits over massed learning Longer Interstudy Intervals (ISI) benefited learning Most studies showed children do better with spaced practice
Research with Children - 1 Rea and Modigliani,1985 3rd graders (8.5 years) taught spelling words and math facts Students ranked as Level 1 (top half of class) or Level 2 (bottom half of class) Results: Better on spelling and math tests with spaced practice rather than massed practice Spaced practice was better for BOTH Level 1 and 2 students (ability level didn’t matter)
Research with Children - 2 Seabrook, Brown & Solity, 2005 Participants ranged from 5-yr olds to undergrads Experiment 1 Task: Ss saw a list of words (3- and 4-letter concrete nouns) and then were given a recall test. Schedule: Words were presented for study with massed practice or spaced/distributed practice. Results: All age groups benefited from increasing spaced practice
Seabrook, Brown & Solity, 2005 Experiment 2 Task: recognize words previously seen on a list under conditions that more closely resembled a classroom Schedule: massed condition = one word was presented 4 times in a row. clustered (an intermediate condition) = one word was presented 2x in a row, followed by 8 intervening items, then an additional 2 consecutive presentations of word. distributed condition = 1 word was presented 4 times, with 4 intervening items between each presentation.
Seabrook, Brown & Solity, 2005 Experiment 2 Results distributed condition produced significantly better results on the test than either the clustered or massed conditions the clustered condition resulted in performance that was not any better than in the massed condition these results held for both the children and the adults; there were no significant differences in performance between children and adults
Seabrook, Brown & Solity, 2005 Experiment 3 Task: 34 children (mean age 5 years.6 mos.) taught phonics over 2 weeks Schedule: Clustered or Massed = one, 6-minute session per day within a regular classroom setting. Distributed = three, 2-minute sessions per day within a regular classroom setting Results: Children in distributed condition had test scores 6 times greater than children in clustered condition
Research with Children - 3 Childers and Tomasello, 2002 How many times (and how many days) does a 2-yr old need to hear a word to learn it? In 2 experiments, 2 yr olds were taught novel nouns and verbs over course of one month in sessions lasting min Noun = “This is a wuggy.” Verb = “It’s dacking. See? It dacks.”
Childers and Tomasello, 2002 Experiment 1 Results: Best learning occurred when practice was distributed over 4 days regardless of number of intervening days Children learned words better if they heard word 1x/day for 4 days rather than 8x/day for I day
Childers and Tomasello, 2002 Experiment 2 only nouns 4 exposures to a new word in 1 day varied the number of days children heard the new words 1 to 4 days Varied number of intervening days (ISI) between when children last heard the new word 1, 2, 5 or 10 intervening days
Childers and Tomasello, 2002 Experiment 2 Results The more days children heard the words, the better able they were to learn the words Best = 4 days, 3 days Worst = 1 day, 2 days The number of intervening days (ISI) did not matter and was not helpful. Children did poorly with 1, 2, 5 and 10 intervening days.
Major Findings Spacing (distributing) practices benefited children and adults whether tasks were physical or conceptual. Spacing practice within the day (e.g., three 2- min sessions/day) or across days (e.g., 1x/day for 4 days) benefited children’s learning.
Implications for Education Practice Current laws state that educational practice needs to be research-based (NCLB; IDEIA, 2004) How should we schedule instruction for young children? Massed vs Spaced ? Research supports Spaced How should we schedule the Itinerant SPED teacher’s time? Direct Instruction or Consultation / Coaching? Research suggests Consultation/Coaching
