    Student’s alternative conception Student’s alternative conception Presentation Transcript

    • ALTERNATIVE CONCEPTION BIOLOGY’S CONCEPT: CELL DIVISION V(^_^)V
    • GROUP MEMBERS
      • MUHAMMAD HAFIZ BIN ABD KADIR
      • NURUL FARIHIN BINTI MOHD RADZI
      • EZZA LIYANA BINTI BADRUL HISHAM
      • MUNIRAH BINTI APANDI
      • The cell cycle, or cell-division cycle, is the series of events that takes place in a cell leading to its division and duplication
      • Cell cycle involve the interphase and the mitotic phase or also known as cell division.
      CELL CYCLE
    • Interphase is the phase in the cell cycle in which the cell spends the majority of its time and performs majority of its proposes including preparation for the cell division .
      • Cell division is the process of which parent cell divides to become 2 or more daughter cells.
      • There are two types of cell division, Mitosis and Meiosis .
      • Mitosis - divides the replicated DNA equally thus producing two identical sets of exact genetic copy of the parental nucleus.
      • Meiosis - reduction of the chromosomal number to half of the parental chromosomal numb er.
      CELL DIVISION
    • MITOSIS
    • MEIOSIS I
    • MEIOSIS II
    • TECHNIQUES
      • 2 techniques were used to detect the misconception of students in the topic of cell division:
      • 1) Student’s Drawings
      • 2) Interviews
    • BRAIN STORMING!!
      • 1) STUDENT’S DRAWINGS
      • Teacher showed a model of meiosis and mitosis to students. Then, the students were asked to draw the mitosis and meiosis without looking at the model.
    • 2. INTERVIEWS
      • The students were asked to respond to
      • questions like :
      • What would happen to organelles, such as mitochondria and chloroplast during cell division?
      • Where we can found nucleus in a cell?
      • Which phase does the replication of DNA occur?
      • What do you understand by the word interphase?
      • DNA replication takes place in which process? Meiosis or Mitosis?
      • How do chromosomes formed?
      • In mitosis, which phase does the homologous chromosome separate?
      • What would happen to the number of chromosomes in the prophase and anaphase of mitosis?
      • The example of meiosis process in human?
      • Do the chromosomes always have two chromatids?
      • Which stage the centroles replicated?
      • How diploid cells are formed?
      • During the cell division, what happen to each centriole?
      • Spindle fibres are formed from?
      • Do the centrosomes and centrioles the same thing?
      • Are sister chromatids are homologous chromosome?
    • STUDENT’S ALTERNATIVE CONCEPTION
    • 1) STUDENT’S DRAWING A MODEL OF MEIOSIS AND MITOSIS ARE SHOWN TO STUDENTS. THEN, THE STUDENTS WERE ASKED TO DRAW THE MITOSIS AND MEIOSIS WITHOUT LOOKING AT THE MODEL. WHAT HAPPEN???
    •  
    •  
    • 2)INDIVIDUAL INTERVIEWS : WERE CONDUCTED ABOUT THE DETAILED SUBJECTS WITH RANDOMLY CHOSEN STUDENTS WHO DEMONSTRATED MISCONCEPTIONS. THE PURPOSE WAS TO CHECK THE VALIDITY OF THE INTERPRETATION OF THE DRAWINGS.
    • 1) WHERE ARE THE LOCATION OF CENTRIOLES?
    • A drawing of misconception of “centrioles are found in the nucleus of a cell
    • 2 )“WHEN DOES DNA REPLICATION OCCUR IN A CELL?,”
    • A drawing of misconception of “DNA replication occurs between prophase and metaphase during cell division
    • 3)“WHAT HAPPENS TO THE CELL ORGANELLES DURING THE CELL DIVISION PROCESS?,”
    • A drawing of misconception of “interphase is the resting phase of the mitosis”.
    • 4)“HOW DO THE CHROMOSOMES ACT DURING MITOSIS AND MEIOSIS?.”
    • A drawing of misconception of “the chromosome number is doubled in the prophase of mitosis and halved in the anaphase of mitosis”.
    • 5)HOW DIPLOID CELLS ARE FORMED?
    • A drawing of misconception of “diploid cells are formed as a result of meiosis”.
    • THE END…
      • Thank you (@.@)
