Overview: Bone Markings is a site that contains a PowerPoint presentation of the different types of bony projections and depressions. The presentation is 13 slides long and includes examples and definitions of each type of bony landmark. The target student population would be high school or college general education students. Student learning goals would be to identify and describe the different types of bony landmarks.
Learning Goals: Students will be able to identify the different types of bony landmarks. Students will be able to define the different types of bony landmarks.
Target Student Population: Middle school, high school, undergraduate lower division
Prerequisite Knowledge or Skills: None.
Type of Material: This is a PowerPoint presentation identifying the various bone markings
Recommended Uses: This presentation could be used in the classroom to give a lecture. It could also be assigned as a preview assignment for students to review the content of the presentation and to be prepared for class as used in the flipped classroom pedagogy.
Technical Requirements: Microsoft PowerPoint software or PowerPoint Viewer.

Evaluation and Observation

Content Quality

Rating: 3.5 stars
Strengths:
  • The content is clear and concise
  • The definitions are accurate
  • The presentation summarizes the content well
  • Specific bone markings are labeled correctly
Concerns:
  • Slide 6: the picture on the right side shows both the radius and ulna. The word “ulna” is labeled next to the radius
  • It would be helpful to specifically label the arrows of all the bony markings throughout the presentation. This gives students an example of the bony marking. For example, head of the femur on slide 4 or ramus of the mandible on slide 5
  • It would be helpful to put an arrow pointing to the sinuses in slide 11. Some students may not be familiar with the sinuses
  • Including notes or key points in the “notes” section of the PowerPoint could be useful for both students or instructors
  • There is no consistency in presenting the topic. Some bone markings are appropriately defined and identified with specific terminology (for example: mandibular fossa) while others are left as generic (for example: head, facet, etc.)

Potential Effectiveness as a Teaching Tool

Rating: 3.25 stars
Strengths:
  • The presentation is well designed and organized
  • The presentation uses both pictures and text to present the bony markings
  • A list of the different types of bone projections and bone depressions is presented for review at the end of the presentation
Concerns:
  • There were no learning objectives given
  • The presentation does not engage the learner
  • The presentation is not interactive
  • Some bones are not identified so learners can get confused as to which bone bears the bone marking presented
  • Students may not know what the word “articular” means. A glossary of words may be useful at the end of the presentation
  • The pictures of some of the bones are grainy or blurry. High quality pictures would improve the presentation.

Ease of Use for Both Students and Faculty

Rating: 4.5 stars
Strengths:
  • The presentation is easy to use and navigation is clear
  • The presentation is visually appealing
Concerns:
  • Some bone markings are defined in generic terms
  • In some images, the bones in which the markings are depicted are not identified so it can be confusing especially for learners who have not yet learned to identify the bones

Other Issues and Comments: This is a useful teaching and learning tool but it can use some improvements.
